However, when the vehicle shifts gears, there is a problem that the false triggering of the accelerator pedal cannot be identified.

[0018] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.
[0019] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs.

[0020] Based on the description of the background technology, the current accelerator pedal anti-misstepping function uses sensors to detect obstacles. When there is an obstacle in the driving direction, it determines whether it is anti-misstepping based on the accelerator pedal status. It relies heavily on sensors and is easily triggered by mistake if the driver has an aggressive driving style. In addition, when the driver accidentally steps on the accelerator pedal and there is no obstacle in the driving direction, the anti-misstepping accelerator pedal function cannot be triggered, and the vehicle will still accelerate unexpectedly, causing disturbance to the driver.
[0021] As mentioned above, how to identify the false triggering of the accelerator pedal when the vehicle shifts gears has become an important research issue.
[0022] Based on the above description, if Figure 1 As shown, the vehicle control method proposed in this embodiment includes:
[0023] Step 101, receiving an accelerator pedal request, and determining whether a gear shift request is received.
[0024] In specific implementation, the accelerator pedal request refers to the position signal of the accelerator pedal received by the vehicle control system, which is used to control the output power of the engine and the speed of the vehicle. When the driver steps on the accelerator pedal, the position sensor of the accelerator pedal sends a signal to the Electronic Control Unit (ECU), and the ECU adjusts the fuel injection amount and ignition timing of the engine according to this signal, thereby controlling the acceleration performance of the vehicle.
[0025] A gear shift request refers to a gear shift instruction issued by the driver through the operation of a gear shift mechanism (such as a gear shift lever, gear shift button, etc.) during driving. The gear shift instruction will be recognized and executed by the vehicle's control system to adapt to different driving needs and road conditions.
[0026] When the accelerator pedal request is received, it indicates that the driver has stepped on the accelerator pedal. After receiving the accelerator pedal request, it is determined whether a gear shifting request is received, thereby determining whether a gear shifting operation is performed after the driver has stepped on the accelerator pedal.
[0027] In some scenarios, the driver needs to step on the brake pedal when performing a gear shift operation. Therefore, after the driver steps on the accelerator pedal, by judging whether the driver performs a gear shift operation, it is judged whether the driver accidentally steps on the accelerator pedal when he wants to step on the brake pedal to perform a gear shift operation.
[0028] Step 102, in response to determining that a gear switching request is received, and the target gear to which the gear switching request switches is a driving gear, it is determined that the accelerator pedal is falsely triggered, and the vehicle is controlled not to respond to the accelerator pedal request.
[0029] In specific implementation, the target gear is the gear to which the gear switching request is switched. The driving gear is the gear that controls the vehicle's driving, and the driving gear includes: forward gear (D gear), reverse gear (R gear), low speed gear (L gear) and sports mode (S gear). The non-driving gear is the gear that controls the vehicle's parking, and the non-driving gear includes: parking gear (P gear) and neutral gear (N gear).
[0030] After receiving the accelerator pedal request, a gear shift request is received and the target gear to be switched to is the driving gear. In this scenario, the driver wants to step on the brake pedal to shift gears, but mistakenly steps on the accelerator pedal to shift gears. Therefore, this scenario is determined to be a false trigger of the accelerator pedal, and the vehicle is controlled not to respond to the accelerator pedal request, thereby avoiding unexpected acceleration of the vehicle and ensuring the safety of the driver and passengers.
[0031] Through the above embodiment, an accelerator pedal request is received, and it is determined whether a gear switching request is received. When a gear switching request is received, and the target gear to which the gear switching request is switched is a driving gear, it is determined that the accelerator pedal is falsely triggered, and the vehicle is controlled not to respond to the accelerator pedal request. In this way, after the accelerator pedal request is received, the gear switching request is received and the target gear to which the gear is switched is a driving gear, indicating that the driver wants to trigger the brake pedal to perform a gear shift operation, and the accelerator pedal is falsely triggered, so that the false triggering of the accelerator pedal when the vehicle is shifting gears can be accurately identified, and unexpected acceleration can be avoided by controlling the vehicle not to respond to the accelerator pedal request, thereby ensuring the safety of the driver and passengers.
[0032] In some embodiments, step 102 includes:
[0033] Step 1021, receiving a gear shift request within a preset time after receiving an accelerator pedal request, and obtaining a current vehicle speed.
[0034] Step 1022, in response to determining that the current vehicle speed is less than a preset vehicle speed threshold, and the target gear to which the gear switching request is switched is a forward gear or a reverse gear, it is determined that the accelerator pedal is falsely triggered.
[0035] In specific implementation, in general scenarios, the driver will perform a gear shift operation within a short period of time after stepping on the brake pedal. Therefore, in order to accurately determine whether the driver performs a gear shift operation after stepping on the accelerator by mistake, the time of receiving the accelerator pedal request and the gear shift request are compared to determine whether the gear shift request is received within a preset time after receiving the accelerator pedal.
[0036] If a gear shift request is received within a preset time after the accelerator pedal request is received, it means that the driver wants to perform a gear shift operation after stepping on the brake pedal but accidentally steps on the accelerator pedal, and the accelerator pedal is determined to be mistriggered. If a gear shift request is received after a preset time after the accelerator pedal request is received, it means that the driver accidentally triggers a gear shift operation while controlling the normal driving of the vehicle, and the gear shift is determined to be mistriggered.
[0037] For example, the preset duration is 5 seconds. After receiving the accelerator pedal request, start timing, and determine whether a gear switching request is received within 5 seconds after the start of timing. If the gear switching request is received 3 seconds after receiving the accelerator pedal request, it is determined that the accelerator pedal is falsely triggered. If the gear switching request is received 7 seconds after receiving the accelerator pedal request, it is determined that the gear switching is falsely triggered.
[0038] In general, gear switching can only be performed when the vehicle speed is low. Therefore, in order to more accurately determine whether the driver has accidentally stepped on the accelerator when trying to shift gears, it is determined whether the current vehicle speed is less than a preset vehicle speed threshold.
[0039] If a gear shift request is received within a preset time after an accelerator pedal request is received, the current vehicle speed is less than a preset vehicle speed threshold, and the target gear to which the gear shift request is switched is a forward gear (D gear) or a reverse gear (R gear), it means that the driver wants to step on the brake to perform a gear shift operation, but accidentally steps on the accelerator pedal during this process, thereby determining that the accelerator pedal is falsely triggered. If a gear shift request is received within a preset time after an accelerator pedal request is received, and the current vehicle speed is greater than or equal to a preset vehicle speed threshold, it means that the driver mistakenly triggers a gear shift operation when the gear shift conditions are not met, thereby determining that the gear shift is falsely triggered.
[0040] In summary, if a gear switching request is received within a preset time after receiving an accelerator pedal request, the current vehicle speed is less than a preset vehicle speed threshold, and the target gear to which the gear shift request is switched is a forward gear (D gear) or a reverse gear (R gear), then the accelerator pedal is determined to be falsely triggered. If a gear switching request is received after a preset time after receiving an accelerator pedal request, or the current vehicle speed is greater than or equal to a preset vehicle speed threshold, then the gear switching is determined to be falsely triggered.
[0041] The preset vehicle speed threshold is a critical value for determining whether the vehicle is at a lower speed. For example, the preset duration is 5s, and the preset vehicle speed threshold is 8km / h. If a gear switching request is received 3s after receiving the accelerator pedal request, the current vehicle speed is 5km / h, and the target gear to which the gear shift request is switched is the forward gear (D gear) or the reverse gear (R gear), then the accelerator pedal is determined to be falsely triggered. If a gear switching request is received 7s after receiving the accelerator pedal request, or the current vehicle speed is 10km / h, then the gear switching is determined to be falsely triggered.
[0042] Through the above scheme, when a gear switching request is received within a preset time after receiving an accelerator pedal request, it is possible to accurately identify that the driver wants to step on the brake pedal to perform a gear switching operation but accidentally steps on the accelerator pedal. On this basis, by judging the current vehicle speed, it is possible to more accurately identify whether the driver has the intention to perform a gear shift operation, thereby more accurately identifying whether the driver accidentally steps on the accelerator pedal when performing a gear shift operation. When a gear switching request is received within a preset time after receiving an accelerator pedal request, the current vehicle speed is less than a preset vehicle speed threshold, and the target gear to which the gear switching request is switched is a forward gear (D gear) or a reverse gear (R gear), it is possible to accurately identify that the driver accidentally steps on the accelerator pedal when performing a gear shift operation, thereby determining that the accelerator pedal is falsely triggered.
[0043] In some embodiments, step 1022 includes:
[0044] Step 1022A, in response to determining that the current vehicle speed is less than a preset vehicle speed threshold, and the gear switching request is to switch from a forward gear to a reverse gear, it is determined that the accelerator pedal is falsely triggered.
[0045] Alternatively, in step 1022B, in response to determining that the current vehicle speed is less than a preset vehicle speed threshold, and the gear switching request is to switch from a reverse gear to a forward gear, it is determined that the accelerator pedal is falsely triggered.
[0046] During specific implementation, in some scenarios, when the gear switching request is to switch from a non-driving gear to a driving gear, since the vehicle will not accelerate in the non-driving gear, therefore, when the vehicle's gear switching request is to switch from a non-driving gear to a driving gear, there will be no safety hazard even if the accelerator pedal is mistakenly triggered. Therefore, the situation where the accelerator pedal is mistakenly triggered when switching from a non-driving gear to a driving gear can be ignored, that is, the situation of switching from the parking gear (P gear) and neutral gear (N gear) to the forward gear (D gear) and reverse gear (R gear) is not considered.
[0047] If a gear switch request is received within a preset time after receiving the accelerator pedal request, the current vehicle speed is less than the preset vehicle speed threshold, and the gear switch request is to switch from the forward gear (D gear) to the reverse gear (R gear), it is determined that the accelerator pedal is falsely triggered.
[0048] If a gear switch request is received within a preset time after receiving the accelerator pedal request, the current vehicle speed is less than the preset vehicle speed threshold, and the gear switch request is to switch from the reverse gear (R gear) to the forward gear (D gear), it is determined that the accelerator pedal is falsely triggered.
[0049] For example, the preset duration is 5s, and the preset vehicle speed threshold is 8km / h. If a gear switching request is received 3s after receiving the accelerator pedal request, the current vehicle speed is 5km / h, and the gear switching request is to switch from the forward gear (D gear) to the reverse gear (R gear), then it is determined that the accelerator pedal is triggered by mistake. Alternatively, if a gear switching request is received 3s after receiving the accelerator pedal request, the current vehicle speed is 5km / h, and the gear switching request is to switch from the reverse gear (R gear) to the forward gear (D gear), then it is determined that the accelerator pedal is triggered by mistake.
[0050] Through the above scheme, if a gear switching request is received within a preset time after receiving an accelerator pedal request, the current vehicle speed is less than a preset vehicle speed threshold, and the gear switching request is to switch from the forward gear (D gear) to the reverse gear (R gear) or the gear switching request is to switch from the reverse gear (R gear) to the forward gear (D gear), it is possible to accurately identify the driver's accelerator pedal mis-triggering when performing a gear shift operation. In addition, without considering the situation of switching from the parking gear (P gear) and the neutral gear (N gear) to the forward gear (D gear) and the reverse gear (R gear), the amount of calculation when identifying the accelerator pedal mis-triggering can be reduced, so that the accelerator pedal mis-triggering when the driver performs a gear shift operation can be identified more quickly.
[0051] In some embodiments, step 102 includes:
[0052] Step 1023, controlling the vehicle brakes by not responding to the accelerator pedal request until the vehicle stops, activating the electronic parking brake system after the vehicle stops, and providing an accelerator pedal mis-triggering prompt.
[0053] Step 1024, obtaining the state of the accelerator pedal in real time after the vehicle stops, and determining whether the accelerator pedal is in a triggered state based on the state of the accelerator pedal.
[0054] Step 1025, in response to determining that the accelerator pedal is not in a triggered state, stopping the accelerator pedal false triggering prompt.
[0055] In a specific implementation, the vehicle brakes are controlled by not responding to an accelerator pedal request, and it is determined whether the vehicle is in a parked state; in response to determining that the vehicle is in a stopped state, the electronic parking brake system is activated, and a false accelerator pedal trigger prompt is given.
[0056] Among them, the Electronic Park Brake (EPB) system is also called an electronic handbrake. EPB controls the parking brake through electronic circuits. Its working principle is similar to that of a traditional mechanical handbrake, which controls the parking brake through the friction between the brake disc and the brake pad, but the control method has changed from a mechanical pull rod to an electronic button. When the vehicle is stationary, pull down the EPB switch, the indicator light comes on, and manual parking is completed.
[0057] When the accelerator pedal is triggered incorrectly, the driver can be prompted to "release the accelerator pedal". For example, after the vehicle stops, the electronic parking brake system EPB is activated, the EPB indicator light comes on, and the driver is prompted to "release the accelerator pedal".
[0058] After the vehicle stops, the accelerator pedal status is obtained in real time, and the accelerator pedal is judged to be in the triggered state according to the accelerator pedal status, so as to judge whether the driver has released the accelerator pedal. When the accelerator pedal is not in the triggered state, it means that the driver has released the accelerator pedal, and the accelerator pedal false trigger prompt is stopped, so as to avoid the problem of the accelerator pedal false trigger prompt after the driver releases the accelerator pedal, which affects the user experience.
[0059] Through the above scheme, when the driver identifies that the accelerator pedal is falsely triggered during a gear shift operation, the vehicle can be prevented from unexpected acceleration by controlling the vehicle brakes without responding to the accelerator pedal request until the vehicle stops, thereby ensuring the safety of the driver and passengers. After the vehicle stops, the electronic parking brake system is activated to keep the vehicle parked, further ensuring the safety of the driver and passengers. After the vehicle stops, a false accelerator pedal trigger prompt is issued to facilitate the driver to understand the reason for the vehicle's stop and release the accelerator pedal in time. After the vehicle stops, the accelerator pedal status is obtained in real time, and the accelerator pedal can be accurately judged whether it is in a triggered state according to the accelerator pedal status, thereby accurately judging whether the driver has released the accelerator pedal, so that after the driver releases the accelerator pedal, the accelerator pedal false trigger prompt is stopped, avoiding long-term accelerator pedal false trigger prompts that affect the user experience.
[0060] In some embodiments, step 1023 includes:
[0061] Step 1023A, obtaining the current position of the vehicle, and determining whether the current position satisfies a preset parking condition.
[0062] Step 1023B, in response to determining that the current position satisfies a preset parking condition, controlling the vehicle to brake at the current position until the vehicle stops by not responding to the accelerator pedal request.
[0063] Step 1023C, in response to determining that the current position does not satisfy the preset parking condition, determine a target position that satisfies the preset parking condition, control the vehicle to travel to the target position, and control the vehicle to brake at the target position by not responding to the accelerator pedal request until the vehicle stops.
[0064] In a specific implementation, in the process of controlling the vehicle's brakes by not responding to the accelerator pedal request until the vehicle stops, in order to avoid the problem of the vehicle braking on the driving section affecting driving safety, it is determined whether the current position meets the preset parking condition. Specifically, it is determined whether the current position is the vehicle driving section. Among them, the preset parking condition is not the vehicle driving section.
[0065] When the current position is not a driving section of the vehicle, it is determined that the current position meets the preset parking condition. In this scenario, the vehicle is controlled to brake at the current position until the vehicle stops by not responding to the accelerator pedal request. In this way, when the driver accidentally triggers the accelerator pedal during a gear shift operation, the vehicle is controlled to brake at the current position of the vehicle until the vehicle stops, which can quickly control the vehicle to stop, thereby ensuring the safety of the driver and passengers.
[0066] When the current position is a section where the vehicle is traveling, it is determined that the current position does not meet the preset parking conditions. In this scenario, in order not to affect driving safety, the vehicle is controlled to start the automatic driving mode, and a target position that meets the preset parking conditions is determined. The vehicle is controlled to travel to the target position through the automatic driving mode, and the vehicle is controlled to brake at the target position until the vehicle stops by not responding to the accelerator pedal request. In this way, when the accelerator pedal is mistakenly triggered during the driver's gear shift operation, the vehicle is controlled to brake at the target position that meets the preset parking conditions until the vehicle stops, which can ensure the safety of the driver and passengers without affecting driving safety.
[0067] Through the above scheme, when the current position meets the preset parking conditions, the vehicle can be quickly controlled to stop by not responding to the accelerator pedal request and controlling the vehicle to brake at the current position until the vehicle stops, thereby ensuring the safety of the driver and passengers. When the current position does not meet the preset parking conditions, the automatic driving mode is turned on and the target position that meets the preset parking conditions is determined. The vehicle is controlled to travel to the target position through the automatic driving mode, and the vehicle is controlled to brake at the target position by not responding to the accelerator pedal request until the vehicle stops, thereby ensuring the safety of the driver and passengers without affecting driving safety.
[0068] In some embodiments, step 1023 includes:
[0069] Step 1023a, obtaining the accelerator pedal opening.
[0070] Step 1023b, in response to determining that the accelerator pedal opening is greater than a preset first opening threshold and less than or equal to a preset second opening threshold, a false triggering prompt of the accelerator pedal is displayed on the vehicle screen, and a false triggering alarm is issued.
[0071] Step 1023c, in response to determining that the accelerator pedal opening is greater than a preset second opening threshold, a false triggering prompt of the accelerator pedal is provided through a vehicle-mounted screen display and a voice broadcast, and a false triggering alarm is issued.
[0072] In a specific implementation, during the process of providing the accelerator pedal false triggering prompt, the accelerator pedal false triggering prompting mode is determined according to the accelerator pedal opening, thereby more accurately prompting the driver of the accelerator pedal false triggering.
[0073] When the accelerator pedal opening is greater than the preset first opening threshold and less than or equal to the second opening threshold, it means that the accelerator pedal opening stepped on by the driver is small, and the accelerator pedal false triggering prompt is displayed on the vehicle screen, and a false triggering alarm is issued to help the driver realize the accelerator pedal false triggering. Among them, the first opening threshold is less than the second opening threshold.
[0074] For example, when the accelerator pedal opening is greater than a preset first opening threshold and less than or equal to a second opening threshold, "Please release the accelerator pedal" is displayed on the vehicle screen and an error trigger alarm is issued.
[0075] When the accelerator pedal opening is greater than the second opening threshold, it means that the accelerator pedal opened by the driver is relatively large, and the accelerator pedal mis-triggering prompt is given through the vehicle-mounted screen display and voice broadcast, and a mis-triggering alarm is issued, so as to remind the driver of the accelerator pedal mis-triggering to the greatest extent, so that the driver can quickly realize the accelerator pedal mis-triggering.
[0076] For example, when the accelerator pedal opening is greater than a preset first opening threshold and less than or equal to a second opening threshold, "Please release the accelerator pedal" is displayed on the vehicle screen, "Please release the accelerator pedal" is announced by voice, and an error trigger alarm is issued.
[0077] Through the above scheme, when the accelerator pedal opening is greater than the preset first opening threshold and less than or equal to the second opening threshold, it means that the accelerator pedal opened by the driver is small, and the accelerator pedal false trigger prompt is displayed on the vehicle screen, and a false trigger alarm is issued, so that the driver can easily realize the false trigger of the accelerator pedal. When the accelerator pedal opening is greater than the second opening threshold, it means that the accelerator pedal opened by the driver is large, and the accelerator pedal false trigger prompt is displayed on the vehicle screen and voice broadcast, and a false trigger alarm is issued, so as to remind the driver of the false trigger of the accelerator pedal to the greatest extent, so that the driver can quickly realize the false trigger of the accelerator pedal.
[0078] In some embodiments, after step 102, the method further includes:
[0079] Step 102A, in response to determining that the target gear to which the gear switch request is switched is the parking gear or the neutral gear, determining that the gear switch is falsely triggered, controlling the vehicle not to respond to the gear switch request, and providing a gear switch false trigger prompt.
[0080] In specific implementation, under general scenarios, during normal driving of the vehicle, the driver switches the vehicle gear to the parking gear (P gear) or the neutral gear (N gear), indicating that the driver mistakenly triggered the gear shift operation while controlling the normal driving of the vehicle, and the gear switch is determined to be mistakenly triggered.
[0081] If a gear switch request is received within a preset time after receiving the accelerator pedal request, and the target gear to which the gear switch request switches is the parking gear (P gear) or the neutral gear (N gear), it is determined that the gear switch is falsely triggered.
[0082] After the mis-triggering of the gear shift is identified, the vehicle is controlled not to respond to the gear shift request, thereby preventing the vehicle from switching gears during normal driving and affecting the safety of the driver and passengers. The mis-triggering prompt of the gear shift makes it easier for the driver to be aware of the mis-triggering of the gear shift.
[0083] When the gear shift mis-triggering prompt is performed, the driver may be prompted to "Please stop the vehicle before shifting gears". For example, after the gear shift mis-triggering is identified, the vehicle is controlled not to respond to the gear shift request, and the driver is prompted to "Please stop the vehicle before shifting gears".
[0084] Through the above scheme, if a gear switching request is received within a preset time after receiving an accelerator pedal request, and the target gear to which the gear switching request switches is the parking gear (P gear) or the neutral gear (N gear), it can accurately identify that the driver has mistakenly triggered the gear shift operation during the normal driving of the vehicle. After identifying the mis-triggering of the gear switching, the vehicle is controlled not to respond to the gear switching request, thereby avoiding the gear switching of the vehicle during normal driving and affecting the safety of the driver and passengers. By providing a mis-triggering prompt for the gear switching, the driver can be easily aware of the mis-triggering of the gear switching.
[0085] Through the above embodiment, an accelerator pedal request is received, and it is determined whether a gear switching request is received. When a gear switching request is received, and the target gear to which the gear switching request is switched is a driving gear, it is determined that the accelerator pedal is falsely triggered, and the vehicle is controlled not to respond to the accelerator pedal request. In this way, after the accelerator pedal request is received, the gear switching request is received and the target gear to which the gear is switched is a driving gear, indicating that the driver wants to trigger the brake pedal to perform a gear shift operation, and the accelerator pedal is falsely triggered, so that the false triggering of the accelerator pedal when the vehicle is shifting gears can be accurately identified, and unexpected acceleration can be avoided by controlling the vehicle not to respond to the accelerator pedal request, thereby ensuring the safety of the driver and passengers.
[0086] It should be noted that the embodiments of the present disclosure may be further described in the following manner:
[0087] Step 1: Determine if you accidentally stepped on the accelerator pedal
[0088] (1) When the vehicle speed is greater than 0 km / h and less than 8 km / h in D gear (at this speed, the brake pedal must be pressed to switch to DR gear). If the driver presses the accelerator pedal for T and the target gear is detected to be R gear, it is determined that the accelerator pedal is pressed incorrectly;
[0089] (2) When the vehicle speed in R gear is greater than 0 km / h and less than 8 km / h (at this speed, the brake pedal must be pressed to switch to RD gear). If the driver presses the accelerator pedal for a period of time T before the target gear is detected to be D gear, it is determined that the accelerator pedal is pressed incorrectly;
[0090] (3) In the D or R gear and the vehicle is stationary, if the driver presses the accelerator pedal for a period of time T and the target gear position requested by the driver is detected to be D or R gear, it is determined that the accelerator pedal was pressed incorrectly.
[0091] In addition, when switching gears, the brake pedal needs to be pressed only when switching between PD / R / N, low-speed ND / R, low-speed RD, and low-speed DR. However, when switching between PD / R / N and low-speed ND / R, the vehicle gear is in P / N gear when the accelerator pedal is accidentally stepped on, and no torque will be generated. Therefore, there is no need to consider this working condition, and only low-speed RD switching and low-speed DR switching need to be considered.
[0092] Step 2, when it is determined that the accelerator pedal is accidentally pressed, the vehicle positive torque is cleared, the vehicle is controlled to brake to a stop, the EPB is automatically pulled up after the vehicle stops, and an accelerator pedal accidental pressing alarm is issued.
[0093] Step 3: When the vehicle stops and the driver releases the accelerator pedal, the judgment that the accelerator pedal was accidentally pressed is cancelled and the vehicle resumes normal function.
