An embodiment of the present invention provides a method for controlling an accelerator pedal of a vehicle, and referring to fig. 2, fig. 2 is a schematic flowchart of a first embodiment of a method for controlling an accelerator pedal of a vehicle according to the present invention.
In the present embodiment, the vehicle accelerator pedal control method includes the steps of:
step S10: when the displacement of an accelerator pedal of a target vehicle is detected, the displacement opening information and the displacement change information of the accelerator pedal are acquired.
It should be noted that, when the displacement of the accelerator pedal of the target vehicle is detected, in order to effectively prevent the accelerator pedal of the vehicle from being abnormally stepped by the driver, the present embodiment obtains the displacement opening information and the displacement change information of the accelerator pedal, and determines whether the displacement state of the accelerator pedal is abnormal according to the displacement opening information and the displacement change information, so as to accurately monitor the displacement of the accelerator pedal, and control the target vehicle according to the displacement state determination result, so that the target vehicle can be timely controlled when the accelerator pedal is abnormally stepped, thereby effectively avoiding the safety problem that the output power of the target vehicle is too large due to the abnormal stepping of the accelerator pedal, and greatly improving the safety performance of the vehicle.
It should be understood that the executing body of the method of the embodiment may be a vehicle accelerator pedal control device with data processing, network communication and program running functions, such as an on-board controller, or other devices or devices capable of implementing the same or similar functions, and is described here by taking the vehicle accelerator pedal control device (hereinafter referred to as pedal control device) as an example.
It should be noted that the accelerator pedal may be an accelerator pedal of the target vehicle, that is, a pedal that controls the power output of the target vehicle. The displacement opening degree information may be information related to an opening degree displacement stroke of the accelerator pedal, and for example, the displacement opening degree information may be a ratio of the displacement stroke of the accelerator pedal, a total displacement stroke of the accelerator pedal, or the like. The displacement change information may be information related to a speed of change of the displacement of the accelerator pedal, and for example, the displacement change information may include an acceleration of the displacement of the accelerator pedal.
It should be understood that, in order to accurately obtain displacement information of an accelerator pedal of a target vehicle, the pedal control device of the present embodiment collects a displacement voltage signal value of the accelerator pedal in real time, and when the displacement of the accelerator pedal of the target vehicle is detected, compares the collected voltage signal value with an electrical characteristic curve of the accelerator pedal, and calculates displacement opening information and displacement change information of the current pedal displacement in the entire accelerator pedal.
For example, the pedal control device acquires a displacement voltage signal value of an accelerator pedal in real time, compares the acquired voltage signal value with an electrical characteristic curve of the accelerator pedal when the displacement of the accelerator pedal of the target vehicle is detected, and calculates a driving occupation ratio and displacement acceleration of the current pedal displacement in the whole displacement of the accelerator pedal.
Step S20: and judging whether the displacement state of the accelerator pedal is abnormal or not according to the displacement opening information and the displacement change information.
It should be noted that the displacement state may be a current displacement condition of the accelerator pedal, for example, the displacement state may be a normal displacement state or an abnormal displacement state.
It should be understood that, in order to accurately monitor the displacement state of the accelerator pedal and thus accurately determine whether the acceleration state of the accelerator pedal is abnormal, the pedal control apparatus of the present embodiment determines the total displacement stroke of the accelerator pedal according to the displacement opening information, determines the displacement change rate of the accelerator pedal within a preset time according to the displacement change information, and determines whether the displacement state of the accelerator pedal is abnormal according to the total displacement stroke and the displacement change rate.
For example, the pedal control device compares the collected voltage signal value with an electrical characteristic curve of the accelerator pedal, calculates whether the proportion of the current pedal displacement to the whole accelerator pedal stroke exceeds k%, calculates whether the displacement change rate of the accelerator pedal exceeds j% within the first 0.5s of acceleration if the proportion exceeds k%, and judges that the displacement state of the accelerator pedal is abnormal if the proportion exceeds j%.
Step S30: and controlling the target vehicle according to the displacement state judgment result.
The pedal control device may determine whether the accelerator pedal is in an abnormal displacement state according to the displacement state determination result, and if so, control the target vehicle to perform emergency braking or deceleration; if not, the displacement of the accelerator pedal is responded.
Further, in order to accurately control the target vehicle, the step S30 further includes:
when the displacement state is in an abnormal state, determining a braking strategy according to the displacement state, and performing braking control on the target vehicle based on the braking strategy;
and when the displacement state is not in an abnormal state, controlling the target vehicle to output torque according to the displacement opening information and the displacement change information.
It should be noted that the brake strategy may be a control strategy that controls the subject vehicle to perform emergency braking or deceleration.
It should be understood that, in order to accurately control the target vehicle to improve the user experience and the vehicle safety performance, if the pedal control device of the embodiment determines that the displacement state is the abnormal state, the pedal control device prohibits the response to the current accelerator pedal opening value and controls the target vehicle to brake; and if the displacement state is judged to be the normal state, responding to the opening value of the current accelerator pedal to output torque.
In the embodiment, when the displacement of the accelerator pedal of the target vehicle is detected, the displacement opening information and the displacement change information of the accelerator pedal are acquired, whether the displacement state of the accelerator pedal is abnormal or not is judged according to the displacement opening information and the displacement change information, and the target vehicle is controlled according to the displacement state judgment result; when the displacement of the accelerator pedal of the target vehicle is detected, in order to effectively prevent the accelerator pedal of the vehicle from being abnormally stepped by a driver, the embodiment acquires the displacement opening information and the displacement change information of the accelerator pedal, judges whether the displacement state of the accelerator pedal is abnormal according to the displacement opening information and the displacement change information, thereby accurately monitoring the displacement of the accelerator pedal, and controls the target vehicle according to the displacement state judgment result, so that the target vehicle can be timely controlled when the accelerator pedal is abnormally stepped, the safety problem that the output power of the target vehicle is overlarge due to the fact that the accelerator pedal is abnormally stepped is effectively avoided, and the safety performance of the vehicle is greatly improved.
Referring to fig. 3, fig. 3 is a flowchart illustrating a second embodiment of a method for controlling an accelerator pedal of a vehicle according to the present invention.
Based on the first embodiment, in this embodiment, the step S10 includes:
step S101: acquiring current opening information of an accelerator pedal of a target vehicle;
step S102: when the accelerator pedal is detected to be displaced, acquiring displacement opening information of the accelerator pedal;
step S103: and determining displacement change information according to the current opening information and the displacement opening information.
It should be noted that the current opening degree information may be a current opening degree value of the accelerator pedal, that is, a different angle of the accelerator pedal with respect to the initial position, for example, the pedal control apparatus acquires the current opening degree information of the accelerator pedal of the target vehicle, determines that the current angle of the accelerator pedal with respect to the initial angle is C degrees according to the current opening degree information, and determines that the accelerator pedal is displaced when it is detected that the current angle of the accelerator pedal is changed.
The displacement opening degree information may be information related to an opening degree displacement stroke of the accelerator pedal, and for example, the displacement opening degree information may be a ratio of the displacement stroke of the accelerator pedal, a total displacement stroke of the accelerator pedal, or the like. The displacement change information may be information related to a speed of change of the displacement of the accelerator pedal, and for example, the displacement change information may include an acceleration of the displacement of the accelerator pedal.
It should be understood that, in order to accurately obtain displacement information of an accelerator pedal of a target vehicle, the pedal control device of the present embodiment collects a displacement voltage signal value of the accelerator pedal in real time, and when the displacement of the accelerator pedal of the target vehicle is detected, compares the collected voltage signal value with an electrical characteristic curve of the accelerator pedal, and calculates displacement opening information and displacement change information of the current pedal displacement in the entire accelerator pedal.
For example, the pedal control device acquires a displacement voltage signal value of an accelerator pedal in real time, compares the acquired voltage signal value with an electrical characteristic curve of the accelerator pedal when the displacement of the accelerator pedal of the target vehicle is detected, and calculates a driving occupation ratio and displacement acceleration of the current pedal displacement in the whole displacement of the accelerator pedal.
Further, in order to accurately acquire the displacement variation information of the accelerator pedal, the step S103 may include:
step S1031: determining an opening degree change parameter of the accelerator pedal according to the current opening degree information and the displacement opening degree information;
step S1032: acquiring the current displacement duration of the accelerator pedal;
step S1033: and determining displacement change information according to the current displacement duration and the opening change parameter.
The opening degree change parameter may be a change parameter between an opening degree value after displacement of the accelerator pedal and an opening degree value before displacement, and for example, if the opening degree value after displacement of the accelerator pedal is X and the opening degree value before displacement is Y, the opening degree change parameter is X-Y.
The current displacement time period may be a total time period of displacement of the accelerator pedal, for example, when the displacement time period of the accelerator pedal from the Y opening to the X opening is 0.5s, the current displacement time period is 0.5s.
Further, in order to improve the accuracy of the displacement variation information, the step S1033 may include:
step S1133: determining a first displacement acceleration of the accelerator pedal in the current displacement duration according to the current displacement duration and the opening change parameter;
step S1233: generating a displacement line graph of the accelerator pedal according to the first displacement acceleration, the current displacement duration and the opening change parameter;
step S1333: and determining displacement change information according to the displacement line graph.
It should be noted that the first displacement acceleration may be a displacement acceleration of the accelerator pedal in a current displacement duration, for example, the accelerator pedal is displaced from the position a to the position B, and the pedal control apparatus determines the first displacement acceleration of the accelerator pedal in the current displacement duration according to the current displacement duration and the opening degree variation parameter by acquiring the current displacement duration during which the accelerator pedal is displaced from the position a to the position B and the opening degree variation parameter between the position a and the position B. The displacement line graph may be a displacement characteristic graph of an accelerator pedal.
In the embodiment, the current opening information of an accelerator pedal of a target vehicle is acquired, when the accelerator pedal is detected to be displaced, the displacement opening information of the accelerator pedal is acquired, and displacement change information is determined according to the current opening information and the displacement opening information; according to the invention, the current opening information of the accelerator pedal of the target vehicle is obtained, when the current opening information is detected to be changed, the accelerator pedal is judged to be displaced, the displacement opening information of the accelerator pedal is obtained, and the displacement change information is determined according to the current opening information and the displacement opening information, so that the displacement of the accelerator pedal is monitored in real time.
Referring to fig. 4, fig. 4 is a flowchart illustrating a third embodiment of a method for controlling an accelerator pedal of a vehicle according to the present invention.
Based on the first embodiment, in this embodiment, the step S20 includes:
step S201: and determining the opening amplitude of the accelerator pedal according to the displacement opening information.
It should be noted that the displacement opening degree information may be a displacement duration of the accelerator pedal during the displacement, and the opening degree amplitude of the variation value of the displacement opening degree may be a maximum value of the pedal opening degree of the accelerator pedal during the displacement, for example, the accelerator pedal is detected to be displaced within 1 second, and the opening degree amplitude may be a maximum opening degree value of the accelerator pedal within 1 second.
Step S202: and judging whether the opening amplitude exceeds a preset opening threshold value or not.
It should be noted that the preset opening degree threshold may be a preset threshold for determining whether the displacement opening degree of the accelerator pedal is abnormal, for example, if the opening degree amplitude of the accelerator pedal is j, and the preset opening degree threshold is k, where j is greater than k, it is determined that the opening degree amplitude exceeds the preset opening degree threshold, that is, it is determined that the displacement opening degree of the accelerator pedal is too large.
Step S203: and determining a second displacement acceleration of the accelerator pedal in a preset sampling period according to the displacement change information.
It should be noted that the preset sampling period may be a preset period for adopting the displacement acceleration of the accelerator pedal, and for example, the preset sampling period may be 0.5s or 1 s. The second displacement acceleration may be a displacement variation acceleration of the accelerator pedal within a preset sampling period, for example, the second displacement acceleration may be a displacement variation acceleration of the accelerator pedal within 0.5s.
Step S204: and judging whether the second displacement acceleration exceeds a preset acceleration threshold value.
It should be noted that the preset acceleration threshold may be preset to determine whether the second displacement acceleration during the displacement of the accelerator pedal in the preset sampling period is abnormal, that is, the preset acceleration threshold is used to determine whether the accelerator pedal is suddenly stepped on by the driver.
Step S205: and judging whether the displacement state of the accelerator pedal is abnormal or not according to the acceleration judgment result and the opening judgment result.
In a specific implementation, the pedal control device compares the acquired voltage signal value with an electrical characteristic curve of an accelerator pedal, determines whether the opening amplitude of the accelerator pedal exceeds k, calculates whether the previous accelerator pedal is within the first 0.5s of acceleration if the opening amplitude of the accelerator pedal exceeds k, and determines that the displacement state of the accelerator pedal is abnormal if the second displacement acceleration of the accelerator pedal exceeds j.
Further, in order to accurately determine the displacement state of the accelerator pedal, step S205 may include:
step S2051: acquiring image information of a running environment where the target vehicle is currently located;
step S2052: determining obstacle information in the driving environment according to the image information;
step S2053: determining the current running condition of the target vehicle according to the obstacle information;
step S2054: and judging whether the displacement state of the accelerator pedal is abnormal or not according to the current running condition, the acceleration judgment result and the opening judgment result.
It should be noted that the driving environment may be a road surface environment where the target vehicle is currently driving, for example, the driving environment may be an expressway driving environment, an urban road driving environment, a rural road driving environment, or the like. The obstacle information may be position information, shape information, and the like of an obstacle in front of and to the side of the traveling environment. The current driving condition may be a driving scene of the target vehicle in the current driving environment, for example, the current driving condition may be a high-speed driving condition, a tour driving condition, a crowded road driving condition, or the like.
It should be understood that, in order to determine whether the accelerator pedal is in an abnormal displacement state in the current driving scene in combination with an actual scene, in this embodiment, the pedal control device acquires image information of a driving environment in which the target vehicle is currently located, extracts obstacle information in the driving environment from the image information, determines whether an obstacle exists in the current driving environment according to the obstacle information, and determines a current driving condition of the target vehicle according to the obstacle information, so as to determine whether the target vehicle is in a high-speed driving scene according to the current driving condition, and if the target vehicle is in the high-speed driving scene, when the accelerator pedal displacement opening is too large, determines that the accelerator pedal is in a normal displacement state; if the vehicle is not in the high-speed driving scene, when the accelerator pedal displacement opening is too large, it is determined that the accelerator pedal is in an abnormal displacement state.
In the embodiment, the opening amplitude of the accelerator pedal is determined according to the displacement opening information, whether the opening amplitude exceeds a preset opening threshold value is judged, a second displacement acceleration of the accelerator pedal in a preset sampling period is determined according to displacement change information, whether the second displacement acceleration exceeds a preset acceleration threshold value is judged, and whether the displacement state of the accelerator pedal is abnormal is judged according to an acceleration judgment result and an opening judgment result; according to the embodiment, the displacement state of the accelerator pedal is accurately judged by judging whether the opening amplitude exceeds the preset opening threshold value and judging whether the second displacement acceleration exceeds the preset acceleration threshold value, so that the condition that the accelerator pedal is in an abnormal displacement state cannot be timely detected is effectively avoided, and the safety performance of a vehicle is improved.
