In order to make the technical solutions and advantages of the present application clearer, the following will describe the embodiments of the present application in further detail with reference to the accompanying drawings.
Referring to fig. 1, a signal transmission schematic diagram of a vehicle door anti-pinch reminding system provided by an embodiment of the present application is shown. With reference to fig. 1, it can be seen that the vehicle door anti-pinch reminding system comprises a vehicle body controller 1, an anti-pinch sensor controller 2, an anti-pinch sensor 3 and an instrument panel 4.
The vehicle body controller 1 is used for detecting the state of a vehicle door and sending a vehicle door state signal to the anti-pinch sensor controller 2, and the vehicle door state signal indicates the opening and closing state of the vehicle door. Prevent pressing from both sides sensor controller 2 and be used for receiving door status signal, when door status signal instructs the door to close, control prevents pressing from both sides sensor 3 and gets into operating condition to and receive and prevent pressing from both sides sensor 3 and detect the signal of preventing pressing from both sides that obtains to door department. The anti-pinch sensor controller 2 is further configured to send a mis-pinch reminder signal to the instrument panel 4 in response to the received anti-pinch signal satisfying the reminder condition. The instrument panel 4 is used for carrying out anti-pinch reminding when receiving the mistaken-pinch reminding signal.
For convenience of understanding, the implementation logic of the anti-pinch reminding of the vehicle door anti-pinch reminding system is simply introduced by combining the schematic diagram of the implementation logic of the anti-pinch reminding of the vehicle door anti-pinch reminding system shown in fig. 2.
In the vehicle door anti-pinch reminding system, when the power mode of the whole vehicle is in an ON gear (namely after the whole vehicle is electrified), the vehicle body controller 1 detects the vehicle door state (namely step 101) and sends a vehicle door state signal to the anti-pinch sensor controller 2 (namely step 102). The detection process may be periodic, such as the body controller detecting a door state every first unit time and sending a door state signal to the anti-pinch sensor controller every second unit time. The detection of the door state by the body controller may be achieved by receiving a signal transmitted from a sensor installed at the door. The signal may be a high-low level signal, for example, when the door is in a closed state, the sensor periodically sends a high level signal to the body controller, and when the door is in an open state, the sensor periodically sends a low level signal to the body controller. The first unit time and the second unit time may be the same or different, and the unit time may be 1 second or 5 seconds, etc.
After the anti-pinch sensor controller 2 receives the door status signal sent by the vehicle body controller 1, the open/close state of the door can be determined according to the door status signal (i.e., step 103). For example, the anti-pinch sensor controller 2 determines that the received door status signal is at a high level, such as 1, to determine that the door is in a closed state, and determines that the received door status signal is at a low level, such as 0, to determine that the door is in an open state. If the anti-pinch sensor controller 2 determines that the vehicle door is in the closed state, a control signal is sent to the anti-pinch sensor 3 to control the anti-pinch sensor to enter the working state (i.e., step 104). When preventing pressing from both sides direct integrated on-off element who prevents pressing from both sides sensor 3 in the sensor controller 2, prevent pressing from both sides this on-off element closure of sensor controller 2 also can direct control, and then give and prevent pressing from both sides the power supply of sensor 3, make and prevent pressing from both sides sensor 3 and get into operating condition. Therefore, the anti-pinch sensor can enter a working state after the vehicle door is closed, so that whether mistaken pinching occurs at the position of the closed vehicle door or not is detected in a targeted mode.
After the anti-pinch sensor 3 enters the working state, whether the mistaken pinch occurs at the door can be detected (i.e., step 105). The detection principle of whether mistaken clamping occurs at the position of the car door is different according to different anti-clamping sensors. When preventing pressing from both sides the sensor for optical sensor, can press from both sides the clothing with the help of the door mistake and whether the mistake is pressed from both sides the difference such as light propagation path or light intensity when not pressing from both sides the clothing by mistake and detect and take place the mistake and press from both sides. When preventing pressing from both sides the sensor for pressure sensor, can detect whether the mistake presss from both sides the clothing based on the door mistake presss from both sides the clothing and not the pressure variation of door department when mistake presss from both sides the clothing. When preventing pressing from both sides the sensor for image sensor, can be through monitoring the picture to door department to discern the image and judge whether the door wrongly presss from both sides the clothing. The anti-pinch sensor 3 may periodically send the detected anti-pinch signal to the anti-pinch sensor controller 2, or send the anti-pinch signal to the anti-pinch sensor controller 2 only when certain conditions are met (i.e., step 106). Specific conditions can prevent for example that sensor controller 2 sends interrogation signal to preventing pressing from both sides the sensor, or prevent that the anti-pinch signal that sensor 3 detected satisfies sending conditions (if prevent that pinch signal strength is greater than minimum intensity threshold value, or be less than the maximum intensity threshold value, minimum signal strength when minimum intensity threshold value instructs to prevent pinching sensor normal work, maximum signal strength that can export when maximum intensity threshold value instructs to prevent pinching sensor normal work, wherein, signal strength can have multiple measurement mode, if can be signal amplitude or signal transmission success rate etc.), can guarantee the validity of the signal of transmission like this, avoid invalid signal transmission, extravagant communication resource.
The anti-pinch sensor controller 2 receives the anti-pinch signal and determines whether the anti-pinch signal satisfies a prompt condition (i.e., step 107). When the anti-pinch signal meets the reminding condition, the anti-pinch sensor controller 2 sends a mistaken-pinch reminding signal to the instrument panel 4 (i.e. step 108). When the instrument panel 4 receives the mis-pinching warning signal, it performs anti-pinching warning (i.e., step 109). The reminding condition here refers to a condition for issuing an anti-pinch reminder to the user.
In some embodiments, when the anti-pinch sensor is an optical sensor, the reminding condition may be that the signal intensity value of the anti-pinch signal does not fall within the first range. Wherein, when first scope was closed for the door and the door did not miss article such as press from both sides the clothing, the amplitude scope of preventing pressing from both sides the signal that the sensor detected is prevented pressing from both sides. Therefore, no matter the mistakenly clamped clothes reflect or absorb light, namely, the anti-clamping signal detected by the anti-clamping sensor is in the right side or the left side of the first range, and the mistaken clamping of the vehicle door is determined, so that the detection accuracy is guaranteed.
To sum up, the warning system is prevented pressing from both sides by the door that this application embodiment provided detects the door state by automobile body controller to preventing pressing from both sides sensor controller and sending door status signal, preventing pressing from both sides sensor controller and confirming the door according to door status signal and closing the back, the sensor is prevented pressing from both sides in control and is located to detect the door. Prevent pressing from both sides sensor controller can receive and prevent pressing from both sides the signal of preventing that the sensor sent to when responding to and preventing that the signal of pressing from both sides satisfies the warning condition, send the mistake to the panel board and press from both sides the warning signal, make the panel board remind the user, realized closing the back at the door and whether automatic mistake double-layered clothing of door department detects, and remind the user when judging the door mistake and press from both sides the clothing. Therefore, the user can know the mistaken clamping event at the automobile door more quickly, and then remove clothes at the automobile door more timely, so that the clothes are prevented from being damaged, and the driving safety can be improved.
In some embodiments, the anti-pinch sensor controller 2 may periodically send a mis-pinch warning signal to the dashboard only when the anti-pinch signal is determined to satisfy the warning condition, and the mis-pinch warning signal may be a high level. And when the anti-pinch sensor controller 2 judges that the anti-pinch signal does not meet the reminding condition, the signal is not sent to the instrument panel.
Or, when judging that the anti-pinch signal meets the reminding condition, the anti-pinch sensor controller 2 sends a wrong-pinch reminding signal to the instrument panel, wherein the wrong-pinch reminding signal can be high level, and at the moment, the instrument panel carries out anti-pinch reminding; and when the anti-pinch signal is judged not to meet the reminding condition, a non-mistaken-pinch reminding signal is sent to the instrument panel, the non-mistaken-pinch reminding signal can be at a low level for example, and the instrument panel does not carry out anti-pinch reminding at the moment. In this process, the mis-clamping reminding signal or the mis-clamping reminding signal can also be sent periodically.
That is to say, when preventing pressing from both sides sensor controller and judging that present door mistake and pressed from both sides article such as clothing, send the mistake and press from both sides reminder signal for the panel board prevents pressing from both sides the warning to the user, and then effectually reminds the user.
In one embodiment, the body Controller 1, the anti-pinch sensor Controller 2, and the dashboard 4 are nodes in a vehicle Controller Area Network (CAN), and are in signal communication with each other in the form of CAN signals. Through setting up to a node in the CAN system with preventing pressing from both sides sensor controller 2, CAN guarantee to prevent pressing from both sides and remind relevant signal transmission's high reliability, real-time and flexibility, and then guarantee to prevent pressing from both sides validity, accuracy and the promptness of reminding. The anti-pinch sensor 3 can send an anti-pinch signal to the anti-pinch sensor controller in a hard line signal mode so as to ensure low cost of the vehicle door anti-pinch reminding system.
In one embodiment, the instrument panel 4 performs anti-pinch reminders, including at least one of: popping up reminding characters and making reminding sound. In a specific implementation, the pop-up reminder text may include "the clothes are caught by the door", and the reminder text may be displayed in the reminder interface popped up from the dashboard or in any blank area of the dashboard.
In one embodiment, the anti-pinch reminding is stopped when the duration of the anti-pinch reminding performed by the instrument panel 4 reaches a first duration, wherein the first duration is a duration threshold of the anti-pinch reminding performed by the instrument panel; or, in the process of the anti-pinch reminding performed by the instrument panel 4, if other safety prompting signals are received, the anti-pinch reminding is stopped, and the other safety prompting signals indicate that other safety problems exist in the vehicle and the user needs to be prompted.
In concrete implementation, after the warning signal is pressed from both sides to mistake is received to panel board 4, can continuously prevent pressing from both sides and remind, stop after long reaching first time, can guarantee like this that the panel board prevents pressing from both sides and reminds stopping after a period of time, avoid reminding always to cause too much interference to the user. The first time period may be set according to actual requirements, and may be 3 seconds or 5 seconds.
Or in the process of anti-pinch reminding by the instrument panel, if other safety reminding signals are received, the anti-pinch reminding is stopped. Other safety warning signals include, for example, a door is not closed, a seat belt is not fastened, and the like. When the instrument panel receives such safety prompting signals, the safety problems can be prompted preferentially. That is, the dashboard may classify response priorities of the received various signals, and when receiving the safety prompt signal whose response priority is higher than the erroneous clamping prompt signal, the dashboard may override the response to the erroneous clamping prompt signal with the response to the safety prompt signal whose response priority is higher.
It should be noted that, in the above embodiment, only one example of the first duration, the reminding character, and the like is given, and in a specific application, a specific numerical value of the first duration, content of the reminding character, a display mode, content and size of the reminding sound, and the like may be adjusted according to preferences of different users for the door anti-pinch function, or these settings may be preset by different manufacturers according to requirements before the vehicle leaves the factory.
In one embodiment, the anti-pinch sensor controller 2 is further configured to: after controlling the anti-pinch sensor 3 to enter the working state, if the received vehicle door state signal indicates that the vehicle door is closed, the anti-pinch signal received in the second time length after the vehicle door is closed is responded, the anti-pinch signal received after the second time length after the vehicle door is closed is stopped responding, and the second time length is a time length threshold value when the anti-pinch sensor controller 2 responds to the anti-pinch signal. The second time period may be a time required for the vehicle to perform self-inspection after the entire vehicle is powered on, such as 40 to 60 seconds.
With reference to fig. 3, the logic for implementing anti-pinch reminder in this embodiment further includes the following processes. The anti-pinch sensor controller 2 controls the anti-pinch sensor 3 to enter the working state and receives the anti-pinch signal sent by the anti-pinch sensor 3 (i.e. step 104 and step 106). Before responding to the anti-pinch signal, the anti-pinch sensor controller 2 may determine the closing state of the door again according to the received door state signal (i.e., step 107), if the door state information indicates that the door is closed, respond to the received anti-pinch signal within a second time period from the time of confirming that the door is closed (step 108), and stop responding to the received anti-pinch signal after the second time period has elapsed from the time (step 111); if the door status information indicates that the door is open, step 108 is continued until it is determined that the door is closed, and then a response to the received anti-pinch signal is not made (i.e., step 112). Based on above-mentioned logic, can guarantee to prevent that the sensor controller of pressing from both sides in time controls after the door is closed and prevent that the sensor gets into operating condition to only respond to preventing pressing from both sides the signal in the second time after the door is closed really, can avoid the user to close the door back and open the door again under the state to the mistake clamp incident of door department and carry out invalid detection, improve the pertinence that the mistake pressed from both sides the detection, the time length control of while detection is long for the second, guarantees can not cause too much interference to the user.
In some embodiments, when the anti-pinch sensor controller 2 directly integrates the switch element of the anti-pinch sensor 3, the above steps 108 and 111 can also be implemented by controlling whether to energize the anti-pinch sensor. That is, the anti-pinch sensor controller 2 may energize the anti-pinch sensor during a second time period from the time the door is determined to be closed and respond to the anti-pinch signal, and stop energizing the anti-pinch sensor after the second time period is reached, and then stop detecting the mis-pinch event at the door.
In one embodiment, the anti-pinch sensor controller 2 is further configured to perform an anti-pinch reminder in response to the received anti-pinch signal satisfying a reminder condition. Prevent pressing from both sides sensor control ware 2 through setting up and prevent pressing from both sides when the signal satisfies the warning condition of preventing pressing from both sides received and remind, realized preventing pressing from both sides when the warning at the panel board, prevent pressing from both sides sensor control ware and also prevent pressing from both sides in step and remind, give the more obvious warning of user for the user knows the mistake of door department more easily and presss from both sides the incident.
In some embodiments, prevent pressing from both sides sensor controller 2 and include the speaker, prevent pressing from both sides sensor controller 2 and prevent pressing from both sides and remind, include: and controlling the loudspeaker to emit reminding sound. In this embodiment, directly integrated speaker in preventing pressing from both sides the sensor control ware, when door department mistake presss from both sides the clothing, prevent pressing from both sides the sensor control ware and can directly control the speaker and send and remind sound to it prevents pressing from both sides the warning to more direct quick realization.
In some embodiments, the anti-pinch sensor 3 is mounted in the vehicle rocker panel. Settle in vehicle threshold backplate through preventing pressing from both sides the sensor, can guarantee that the automobile body surface does not have extra arch, and pleasing to the eye degree is higher, and ensures to prevent pressing from both sides the validity that detects, improves the accuracy that detects.
In some embodiments, the anti-pinch sensor is an optical sensor and the upper surface of the vehicle rocker panel has a light transmissive region for transmitting light emitted or received by the anti-pinch sensor. In this embodiment, set up to optical sensor with preventing pressing from both sides the sensor, detect the door and locate the change of light propagation path or intensity and carry out the mistake and press from both sides and detect. In order to ensure that the optical sensor normally emits light and receives light, a light-transmitting area is arranged on the upper surface of the vehicle doorsill guard plate, and the light-transmitting area corresponds to the arrangement area of the optical sensor.
In some embodiments, the vehicle rocker panel may include a light-transmitting cover, a lower case, and a Circuit Board (PCB), where the light-transmitting cover and the lower case together form a case having a cavity structure inside, the Circuit Board is disposed in the case, the anti-pinch sensor is disposed on the Circuit Board, and the disposing manner may be set according to actual requirements, for example, may be a snap-fit manner. This printing opacity cover can see through and prevent that the clamp sensor sends or the light of receiving. Therefore, the vehicle doorsill guard plate can transmit light rays in a large range, and the anti-pinch sensor is large in detection range.
In some embodiments, referring to fig. 4, the anti-pinch sensor 3 includes an infrared light emitting device 31 and an infrared receiving device 32. The infrared light emitting device 31 is for emitting infrared light; the infrared receiving device 32 is used to receive infrared light reflected by an object at the door of the vehicle. The object is the obstacle shown in fig. 4, light emitted from the infrared light emitting device 31 is incident on the surface of the obstacle, the obstacle reflects part of the light, and the reflected light is received by the infrared receiving device 32, so that the infrared receiving device 32 outputs a corresponding electrical signal.
The infrared receiving device 32 here may be an optoelectronic proximity sensor. When the reflected light rays with different intensities are received, the photoelectric proximity sensor can output electric signals with different amplitudes.
Specifically, when no obstacle such as clothes exists in a certain distance range above the infrared receiving device, the infrared receiving device can only receive light reflected by the lower surface of the vehicle door, the intensity of the light at the moment can be calibrated, the amplitude range of the output electric signal corresponding to the light intensity which can be received by the infrared receiving device when the vehicle door is closed and the clothes are not clamped by mistake is determined, and the range is determined as a first range. When clothes are mistakenly clamped by the vehicle door within a certain distance range above the infrared receiving device, the light intensity of the light received by the infrared receiving device is different from the light intensity of the light reflected by the lower surface of the vehicle door independently, and then the electric signal with the amplitude value not within the first range can be output. Or, when an obstacle exists in a certain distance range above the infrared receiving device and the obstacle approaches or leaves (the distance between the clothes and the infrared receiving device may change due to various actions of the user), the light intensity of the light received by the infrared receiving device changes accordingly, and then an electric signal with continuously changing amplitude is output.
Correspondingly, prevent pressing from both sides sensor controller 2 and realize preventing pressing from both sides through following logic and remind: when the anti-pinch signal received by the anti-pinch sensor controller 2 is unchanged and is within the first range, the fact that the vehicle door does not clamp clothes by mistake is confirmed, and anti-pinch reminding is not performed; when the anti-pinch signal received by the anti-pinch sensor controller 2 is unchanged and does not belong to the first range, the anti-pinch sensor controller determines that the vehicle door mistakenly pinches clothes, and performs anti-pinch reminding; when the anti-pinch signal received by the anti-pinch sensor controller 2 changes, it is determined that obstacles such as clothes and the like are likely to move at the car door, and anti-pinch reminding is not performed. The anti-pinch signal output by the anti-pinch sensor is a digital signal obtained by analog-to-digital conversion (ADC).
In the process, the anti-pinch sensor controller 2 CAN periodically send a CAN signal to the instrument panel 4, wherein when the anti-pinch signal is unchanged and is within a first range and the anti-pinch signal continuously changes, the CAN signal is a non-mistaken-pinch reminding signal, if the CAN signal CAN be a low level, and when the instrument panel receives the non-mistaken-pinch reminding signal, the anti-pinch reminding is not carried out; when the anti-pinch signal is unchanged and does not belong to the first range, the CAN signal is a mistaken-pinch reminding signal, if the CAN signal CAN be a high level, when the instrument panel receives the mistaken-pinch reminding signal, anti-pinch reminding is carried out.
In some embodiments, the amplitude range of the anti-pinch signal can be calibrated to obtain a second range when clothes exist within a certain distance range above the anti-pinch sensor. Furthermore, when the anti-pinch signal received by the anti-pinch sensor controller 2 is unchanged and belongs to a second range, the mistaken clothes clamping of the vehicle door is confirmed; when the anti-pinch signal is not changed and does not belong to the second range, the vehicle door is determined not to clamp the clothes by mistake (if the first range and the second range do not intersect, the vehicle door can be further determined not to clamp the clothes by mistake when the anti-pinch signal is not changed and belongs to the first range). Wherein, the calibration process may include: and when clothes made of different materials are arranged in a certain distance range above the infrared light-emitting device and the infrared receiving device, the amplitude of an electric signal output by the infrared receiving device is obtained, and a range formed by the minimum value and the maximum value of the amplitude is used as the second range.
In some embodiments, the anti-pinch sensor 3 may be provided in a plurality of sets, such as 6 or 8, disposed in the vehicle rocker panel along the length of the vehicle rocker panel. Multiple sets of anti-pinch sensors disposed in the vehicle sill guard may collectively form a strip. Referring to fig. 5, an arrangement of at least two sets of anti-pinch sensors 3 and anti-pinch sensor controllers 2 is shown, where each set of anti-pinch sensors 3 has the same input voltage Vcc, and all sends the output electrical signal to the anti-pinch sensor controllers 2. In some embodiments, the anti-pinch sensor controller 2 may process the output electrical signals of at least two sets of anti-pinch sensors 3 as anti-pinch signals, such as averaging or weighted summation.
In some embodiments, a vehicle rocker panel with an anti-pinch sensor can be mounted on at least one of a primary driving side, a secondary driving side, a rear left side, or a rear right side.
In some embodiments, the door anti-pinch reminder system can also include a vehicle terminal. Can show the switch controlling part of preventing pressing from both sides warning function on this vehicle-mounted terminal, the display state of this switch controlling part is used for instructing the operating condition who prevents pressing from both sides sensor 3. Through the information interaction between the vehicle-mounted terminal and the anti-pinch sensor controller, the anti-pinch reminding function can be started or closed. Specifically, a user can change the on-off state of the anti-pinch reminding function by pressing or touching the switch control, and when the vehicle-mounted terminal detects the triggering operation of the switch control, a switching control signal is sent to the anti-pinch sensor controller; when the anti-pinch sensor controller receives the switching control signal, the working state of the anti-pinch sensor is switched; when the anti-pinch sensor controller switches the working state of the anti-pinch sensor, a feedback signal is sent to the vehicle-mounted terminal; and after the vehicle-mounted terminal receives the feedback signal, updating the display state of a switch control of the anti-pinch reminding function, wherein the display state of the switch control comprises an opening state and a closing state.
Can show on the on-vehicle terminal that the switch controlling part of reminding the function is prevented pressing from both sides by main driving side, vice driving side prevent pressing from both sides the switch controlling part of reminding the function, the switch controlling part of reminding the function is prevented pressing from both sides in back row left side and the back row right side prevent pressing from both sides at least one of the switch controlling part of reminding the function, guarantee that the user can select to open the anti-pinch of the door department that easily appears the mistake clamp incident according to actual conditions by oneself and remind the function, and then improve the flexibility and the pertinence that the door prevented pressing from both sides and reminds.
