Referring to fig. 2, a control device 300 according to an embodiment of the present disclosure includes:

an acquisition module 310 for periodically acquiring a current position of the key 200 relative to the car 100;

a confirmation module 320 for determining a functional area where the key 200 is currently located based on the current position, the functional area being an area divided around the automobile 100;

a control module 340 for setting the functional area where the key 200 is located in the same functional area for more than a predetermined number of times as a target functional area; and is used for controlling the automobile 100 to execute the preset function corresponding to the target functional area.

The automobile 100 according to the embodiment of the present application includes a memory 10 and a controller 20, and the controller 20 is configured to execute a calculation program stored in the memory 10 to implement the control method according to the embodiment. Or the controller 20 is used to periodically acquire the current position of the key 200 relative to the car 100; and a function area for determining the current location of the key 200 based on the current location, the function area being an area divided around the automobile 100; and for counting the number of times the key 200 is respectively located in different functional areas within a predetermined number of cycles in each cycle; and a function area for setting the number of times the key 200 is located in the same function area to be greater than a predetermined number of times as a target function area; and is used for controlling the automobile 100 to execute a preset function corresponding to the target function area.

In the control method, the control device 300 and the automobile 100 according to the embodiment of the application, when the control device 300 realizes the control method to enable the key 200 to be located near the boundary line of different functional areas of the automobile 100, the automobile 100 is controlled to execute the preset function of the corresponding functional area only when the preset number of times is exceeded in a preset number of cycles, and therefore frequent random switching of the preset functions of adjacent functional areas is reduced, and the loss of the execution parts of the automobile 100 is reduced.

Specifically, the vehicle 100 may be a new energy vehicle, a fuel vehicle, a hybrid vehicle, or the like. The key 200 of the automobile 100 may be a device used to enter the automobile 100, lock the automobile 100, or perform some function on the automobile 100. The key 200 may be a remote control key, a key to which various wireless technologies are applied, or a digital key in an electronic device such as a mobile phone. For example, the key 200 may be a UHF key fob, a UWB digital key, and the like. The vehicle 100 may include a controller 20 and a memory 10, and the vehicle 100 may implement a control method through the controller 20 and the memory 10.

In the control method, the controller 20 may periodically acquire the key 200 with respect to the automobile 100 and the current position, and the periodic acquisition may be acquisition of a period duration or acquisition of a number of periods, in which the control method may be implemented as step S10. The obtaining mode may adopt positioning technologies such as a positioning calculation system of the automobile 100 to the key 200, for example, the positioning calculation system may include visual auxiliary positioning at the automobile end, relative positioning of an accelerometer at the key 200 end, and the like; the coordinates of the key 200 relative to the coordinate system of the car 100 itself can be obtained by positioning the key 200 by the car 100, and the current position between the car 100 and the key 200 can be obtained.

Step S20 may be further taken, and based on the current position obtained in step S10, the functional area where the key 200 is located may be confirmed. The confirmation mode may be to determine whether the key 200 or the user carrying the key 200 is in the functional area through the relative relationship between the current position of the key 200 and the automobile 100 and by combining a positioning technology.

As shown in fig. 3, it should be understood that the functional area of the automobile 100 may be divided according to different positions around the automobile 100, a distance range outside the outer contour line of the automobile 100 may be divided into the main functional area 30, and a specific value of the distance range may be selected to be about 0 m to 2 m. The distance range outside the main functional area 30 of the automobile 100 can be divided into a plurality of secondary functional areas 40, and the specific value of the distance range of the plurality of secondary functional areas 40 can be selected to be divided into a plurality of distance segments from about 2 meters to about 30 meters.

The main functional area 30 may be divided into a plurality of functional blocks according to different components of the automobile 100, for example, the main functional area 30 of the automobile 100 is divided into 6 functional blocks, including a front left door functional block 31, a rear left door functional block 32, a front right door functional block 33, a rear right door functional block 34, a rear left door functional block 35 and a rear right door functional block 36. When the key 200 is located in each functional block, the automobile 100 may unlock the corresponding functional block, for example, unlocking the front left door, unlocking the rear left door, and the like. When the key 200 leaves each functional block, the car 100 may implement the lock-down of the corresponding functional block, for example, the lock of the front left door, the lock of the rear left door, and so on. Of course, the specific functions of the functional blocks may be set to other functions.

In the sub-functional area 40, the boundary of the main functional area 30 to the plurality of sub-functional areas 40 may be a circular block, as shown by the sub-functional areas 40 of the circular block surrounded by two phases. When the key 200 is located in the annular block, the automobile 100 may be controlled to perform one or more of the functions of turning on a courtesy light, adjusting a seat, turning on an air conditioner, remotely parking, or automatically following. Further, the function of the sub-functional area 40 can be customized according to the actual or user requirement of the automobile 100.

It should be further understood that, because the position of the key 200 obtained by the positioning technology such as the positioning calculation system is output by a random probability distribution centered on the actual position of the key 200, when the key 200 is located near the function dividing boundary, the position coordinates of the key 200 output by the positioning calculation system will randomly fall into the function area adjacent to the boundary; if not, it will happen that the functional area will frequently and randomly execute the preset function; a phenomenon similar to this is commonly referred to as a ping-pong effect of the functional zone boundaries.

Therefore, step S30 may be taken to count the number of times the key 200 is located in different functional zones for a predetermined number of cycles per cycle. The predetermined number of cycles may be a specific number of cycles set in advance for the key 200 acquired in step S10 with respect to the current position of the automobile 100, and the predetermined number of cycles may be 5 cycles, 10 cycles, or the like. After each cycle in the predetermined number of cycles has been completed to confirm the functional zone in which the key 200 is located in step S20, the number of times the key 200 is located in the different functional zones for the entire predetermined number of cycles is counted.

Then, step S40 may be taken, in which the number of times of falling in each functional area is counted in a predetermined number of cycles, and each functional area is provided with a predetermined number of times, and when the number of times of falling in a certain functional area by the key 200 in the predetermined number of cycles is greater than the predetermined number of times, the controller 20 may regard the functional area satisfying the requirement as the target functional area.

Step S50 may be performed, and after the target functional area is determined, the controller 20 may control the automobile 100 to implement a preset function of the target functional area, where the preset function may be unlocking of the corresponding functional area, or turning on light of the corresponding functional area.

Referring to fig. 4, in some embodiments, the current position of the key 200 relative to the automobile 100 is periodically obtained (step S10), which includes:

s11, periodically acquiring the current distances between a plurality of UWB anchor modules 50 on the automobile 100 and the key 200 respectively, wherein the UWB anchor modules are positioned at different positions of the automobile 100;

s12, calculating the current position of the key 200 relative to the automobile 100 based on the plurality of current distances.

The acquiring module 310 is configured to periodically acquire current distances between the UWB anchor modules 50 on the automobile 100 and the key 200, respectively, where the UWB anchors are located at different positions of the automobile 100; the calculation module 330 is configured to calculate a current position of the key 200 relative to the automobile 100 based on the plurality of current distances.

The controller 20 is configured to periodically obtain current distances from the key 200 to a plurality of UWB anchor modules 50 of the automobile 100, respectively, the plurality of UWB anchor modules being located at different positions of the automobile 100; and for calculating the current position of the key 200 relative to said car 100 based on a plurality of current distances.

In this manner, a more accurate current location of key 200 may be obtained by the plurality of UWB anchor modules 50 of vehicle 100, which may in turn be a more accurate determination of the functional zone in which key 200 is located.

Specifically, the UWB technology based on the related standards such as 802.15.4z, also called as a security enhanced ultra-wideband technology, may be mainly applied to the digital key 200 system of the automobile 100, and has the technical characteristics of relay attack prevention, high ranging and positioning accuracy; the key 200 can be identified inside and outside the vehicle and positioned accurately outside the vehicle functionally. The precision can reach +/-6-10 cm under the non-shielding condition, and the precision can reach +/-30 cm under the shielding condition.

The digital key 200 system using UWB technology can provide functions such as a non-inductive unlock, a non-inductive start-up ignition, and the like with good user experience. Exemplarily, by adopting a security enhanced UWB technology, a low power consumption Bluetooth (BLE) technology and a Near Field Communication (NFC) technology based on 802.15.4z, electronic devices such as mobile phones can be used to realize the non-inductive unlocking and starting of the vehicle, the remote sharing of the digital key 200 can be conveniently performed, the vehicle can be conveniently shared with family members, and friends can also be authorized to use the vehicle in a short time.

To implement step S10, step S11 may be taken, and the controller 20 may periodically acquire the current distance between each UWB anchor module 50 of the plurality of UWB anchor modules 50 on the automobile 100 and the UWB module on the key 200, wherein the plurality of UWB anchor modules 50 may be disposed at different positions of the automobile 100, for example, may be disposed near four corners (left front/left rear/right front/right rear) of the automobile 100 and near front and rear doors of the automobile 100.

Step S12 may then be taken, the relative position of the key 200 and the automobile 100 is located based on the plurality of current distances acquired in step S11, and then the functional region where the key 200 is located may be confirmed by calculating the relative position.

Illustratively, as can be further understood in conjunction with fig. 5, during the signal connection and positioning process between the key 200 based on UWB technology and the automobile 100, the automobile body may be provided with an ultrasonic module and a vision-aided module, and the key 200 may be provided with a module for positioning, such as a UWB module, a bluetooth low energy module, a GPS module, etc., which may include corresponding chips and modules; the bluetooth low energy module in the key 200 and the bluetooth low energy module in the car 100 can realize wireless communication, and the UWB module in the key 200 and a plurality of UWB anchor modules 50 distributed in the car 100 carry out ToF range finding to can acquire the current distance of the key 200. Then, the ToF distance and the received signal strength information between each of the UWB anchor modules 50 at the end of the vehicle 100 and the UWB module of the key 200 may be sent to the controller 20 of the vehicle 100 to perform the position calculation of the key 200, so as to obtain the relative position of the key 200, and the information obtained by the ultrasonic module and the visual module of the vehicle body may also be used for assisting the calculation of the relative position of the key 200. The controller 20 then further determines the functional zone in which the key 200 is located based on the relative position of the key 200 with respect to the vehicle 100.

Referring to fig. 6, in some embodiments, the counting the number of times that the key 200 is respectively located in different functional areas within a predetermined number of cycles (step S30) includes:

s31, counting the functional area where the key 200 is located once in each period;

and S32, confirming the times that the keys 200 are respectively positioned in different functional areas according to the counting result in a preset period.

The calculation module 330 is configured to count the functional area where the key 200 is located once in each cycle; and a number of times for confirming that the key 200 is located in the different functional areas, respectively, according to the result of the counting within a predetermined number of cycles.

The controller 20 is configured to count the functional region in which the key 200 is located once per cycle; and the number of times for confirming that the keys 200 are respectively located in different functional areas according to the counted result within a predetermined number of cycles.

Thus, the number of times that the key 200 is located in different functional areas in the cycle can be recorded by adopting a counting mode, so that the key 200 can be conveniently positioned between different functional areas for comparison, and the judgment of subsequent steps is facilitated.

Specifically, the controller 20 performing step S30 may first take step S31, count the functional region where the key 200 confirmed in step S20 is located once in each of the predetermined number of cycles, and then count the corresponding number of times the key 200 is located in the different functional regions confirmed in the predetermined number of cycles.

As will be further understood in conjunction with the embodiment of fig. 7, taking the left front door functional block 31 and the left rear door functional block 32 shown in fig. 3 as an example, the controller 20 in the automobile 100 may execute step S30 when the key 200 is located at different positions from the boundary line of the two functional blocks. The number of times that the automobile 100 calculates in the predetermined number of cycles may adopt a sliding window counting manner in software logic, taking a sliding window shift register set as an example:

when the key 200 is located in the left front door functional block 31, the sliding window shift register set in the left front door functional block 31 can receive the confirmation message and record in the manner of 0 and 1, and the falling left front door functional block 31 is marked as 1 (shaded unit of the shift register set in the figure), otherwise, it is marked as 0 (blank unit of the shift register set in the figure). The length of the sliding window shift register set can be regarded as a predetermined number of cycles, and the predetermined number of cycles in the figure is 10; each sliding window shift register group is accompanied with a counting accumulator which is used for calculating the number of '1' in the sliding window shift register group;

when the key 200 is at a certain distance from the boundary line in the left front door functional block 31, the position of the key 200 is determined to be close to the normal distribution curve of the left front door functional block 31. At this time, the sliding window shift register set in the front left door functional block 31 confirms that the key 200 falls into the front left door functional block 31 for 9 times within 10 predetermined number periods, wherein the number of times accumulated by the corresponding count accumulator is 9. Meanwhile, the sliding window shift register set in the left back door functional block 32 only confirms that the key 200 falls into the left front door functional block 31 for 1 time within 10 predetermined number periods, wherein the number of times of accumulation of the corresponding count accumulator is 1.

The predetermined number of times is selected to be 7 times, and the number of times accumulated by the counting accumulator in the left front door functional block 31 is greater than 7 times. Therefore, the left front door functional block 31 may be determined as the target functional area according to the step S40, and then the automobile 100 may be controlled to execute the preset function corresponding to the target functional area. For example, unlocking of the left front door.

In this manner, the predetermined number of cycles being the latest predetermined number of times from the present time ensures that the confirmation and counting of the functional zone in which the key 200 is located is in the latest state.

Specifically, still taking the 10 predetermined cycles selected in fig. 7 as an example, when the confirmation information received by the sliding window shift register set is more than 10 times, for example, 13 times, the sliding window shift register set should take the 10 times that the current time is the latest cycle as the predetermined cycles.

Referring to fig. 8, in some embodiments, the control method further includes:

and S60, in the case that the number of times that the key 200 is located in the same functional area is less than or equal to the preset number of times, keeping the function currently executed by the automobile 100.

The control module 340 is configured to maintain the function currently performed by the vehicle 100 if the key 200 is located in the same functional zone less than or equal to the predetermined number of times. The controller 20 is configured to maintain the function currently performed by the vehicle 100 in a case where the number of times the key 200 is located in the same functional zone is less than or equal to a predetermined number of times.

In this way, in the case that the number of times that the key 200 is located in the same functional zone is less than or equal to the predetermined number of times, maintaining the function currently performed by the automobile 100 may reduce the frequent switching of the performing functional zone of the automobile 100 caused by the ping-pong effect of the key 200 being located in the boundary line.

Specifically, the controller 20 may perform step S60 when the control method goes to step S30 and step S40 is not satisfied, and maintain the function currently performed by the automobile 100 in a case where the keys 200 are located in the same functional zone less than or equal to the predetermined number of times.

As will be understood from fig. 9, when the key 200 is close to the boundary line in the left front door functional block 31, the position of the key 200 is determined to be a normal distribution curve close to the boundary line. At this time, the sliding window shift register set in the front left door functional block 31 confirms that the key 200 falls into the front left door functional block 31 7 times within 10 predetermined number periods, wherein the number of times accumulated by the count accumulator is 7. Meanwhile, the sliding window shift register set in the left back gate functional block 32 only confirms that the key 200 falls into the left front gate functional block 31 3 times within 10 predetermined number periods, wherein the number of times accumulated by the corresponding count accumulator is 3.

The predetermined number of times is selected to be 7, the number of times accumulated by the counting accumulator in the front left door functional block 31 is equal to 7, and the number of times accumulated by the counting accumulator in the rear left door functional block 32 is less than 7. Therefore, according to step S60, if the target function block executed by the vehicle 100 is the unlocking of the left front door function block 31, the vehicle 100 can maintain the unlocked state of the left front door function block 31.

As can be further understood with reference to fig. 10, when the position of the key 200 is moved to the boundary line between the front left door functional block 31 and the rear left door functional block 32, the position of the key 200 is determined to be a normal distribution curve centered on the boundary line. At this time, the sliding window shift register set in the front left door functional block 31 confirms that the key 200 falls into the front left door functional block 31 5 times within 10 predetermined number periods, wherein the number of times accumulated by the corresponding count accumulator is 5. At the same time, the sliding window shift register set in the left back door functional block 32 confirms that the key 200 falls into the left front door functional block 31 5 times within 10 predetermined number periods, wherein the number of times the corresponding count accumulator is accumulated is 5 times.

The predetermined number of times is selected to be 7 times, and the number of times accumulated by the counting accumulator in the front left door functional block 31 and the number of times accumulated in the counting accumulator in the rear left door functional block 32 are equal to each other and are less than 7 times. Therefore, according to step S60, if the target function block executed by the vehicle 100 is the unlocking of the left front door function block 31, the vehicle 100 can maintain the unlocked state of the left front door function block 31.

Thus, a value of the predetermined number of times greater than half the value of the predetermined number of cycles may make the confirmation of the key 200 function area by the automobile 100 realistic.

Specifically, the value of the predetermined number of times is set to be greater than half of the value of the predetermined number of cycles, i.e., the value of the predetermined number of times is 50% or more of the value of the predetermined number of cycles, and preferably, the value of the predetermined number of times may be 60% or more of the value of the predetermined number of cycles.

Referring to fig. 11, in some embodiments, the control method includes:

and S70, controlling the automobile 100 to stop executing the functions corresponding to the other functional areas under the condition that the automobile 100 executes the preset functions corresponding to the target functional areas.

In this way, the automobile 100 can be prevented from conflicting with functions performed by other function areas when performing the preset function of the target function area.

Specifically, referring to the functional areas of the automobile 100 in fig. 3, when the controller 20 of the automobile 100 executes the control method and confirms that the execution target functional area is the unlock function of the front left door functional block 31, the automobile 100 stops controlling the functions executed by the other functional areas except the target functional area, such as the rear left door functional block 32, the front right door functional block 33, the rear right door functional block 34, the rear left door functional block 35, and the rear right door functional block 36.
