[0039] In the present disclosure, when a specific component is described as being located between a first component and a second component, there may or may not be an intervening component between the specific component and the first component or the second component. When a specific component is described as being connected to another component, the specific component may be directly connected to the other component without an intervening component, or may not be directly connected to the other component but have an intervening component.

It should also be understood that terms defined in, for example, general dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or highly formal sense, unless explicitly defined herein.

[0041] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0042] The current technical solution is only applicable to the vehicle's starting phase and only outputs warning information about accidental accelerator pedaling. The scenario coverage is not high and it cannot control the vehicle to reduce collision losses.

[0043] like Figure 1 and Figure 2 As shown, the low-speed accelerator accidental pressing suppression method provided by this embodiment includes the following steps in actual implementation:

[0044] Step S1: Collect obstacle information in front of and behind the vehicle.

[0045] In one embodiment of the method for suppressing accidental low-speed accelerator pedaling of the present invention, step S1 may specifically include:

[0046] Step S11: Utilize multiple ultrasonic radars arranged in front of the vehicle to sense obstacle information in front of the vehicle.

[0047] Step S12: Utilize multiple ultrasonic radars arranged at the rear of the vehicle to sense obstacle information behind the vehicle.

[0048] The number of ultrasonic radars at the front and rear of the vehicle is four. It should be noted that the present invention does not specifically limit the number and distribution of ultrasonic radars at the front and rear of the vehicle. The present invention uses four ultrasonic radars at the front and four ultrasonic radars at the rear to provide full coverage monitoring of the vehicle's front and rear areas, obtaining information on the locations of obstacles in front and behind the vehicle. Ultrasonic radars have high obstacle recognition accuracy at the near end and are effectively applicable to low-speed vehicle scenarios.

[0049] Step S2: Collect the vehicle's throttle opening information and vehicle speed information.

[0050] Specifically, the vehicle's throttle opening information and vehicle speed information are collected through CAN signals.

[0051] Step S3: determining whether a starting accelerator accidental depression suppression condition or a low-speed driving accelerator accidental depression suppression condition is satisfied based on the obstacle information, the accelerator opening information, and the vehicle speed information.

[0052] In one embodiment of the method for suppressing accidental low-speed accelerator pedaling of the present invention, step S3 may specifically include:

[0053] Step S31: Determine whether the obstacle is within a set distance range D based on the obstacle information.

[0054] Step S32: If yes, the distance between the obstacle and the vehicle satisfies the distance condition;

[0055] Step S33: determining whether the throttle opening is greater than a preset throttle opening threshold T based on the throttle opening information;

[0056] Step S34: If yes, the throttle opening satisfies the depth condition;

[0057] Step S35: determining, based on the vehicle speed information, whether the vehicle speed is lower than the starting speed V1 or whether the vehicle speed is greater than the starting speed V1 and less than the vehicle low-speed driving speed V2;

[0058] Step S35: If the distance between the obstacle and the vehicle satisfies the distance condition, the throttle opening satisfies the depth condition, and the vehicle speed is lower than the starting speed V1, then the starting throttle mis-operation suppression condition is satisfied.

[0059] Step S36: If the distance between the obstacle and the vehicle satisfies the distance condition, the throttle opening satisfies the depth condition, and the vehicle speed is greater than the starting speed V1 and less than the low-speed driving speed V2, then the low-speed driving throttle accidental pressing suppression condition is met.

[0060] Step S4: If the starting accelerator accidental pressing suppression condition or the low-speed driving accelerator accidental pressing suppression condition is met, the vehicle is controlled to stop.

[0061] Based on the obstacle information, throttle opening information, and vehicle speed information, it is determined whether the starting throttle accidental depression suppression conditions or low-speed driving throttle accidental depression suppression conditions are met, that is, it is determined whether there is a collision risk during the starting phase and low-speed driving. When there is an obstacle collision risk, the throttle accidental depression suppression is implemented in low-speed scenarios, thereby avoiding vehicle collision losses and protecting the user's life and property safety. In one embodiment of the low-speed throttle accidental depression suppression method of the present invention, the step S4 may specifically include:

[0062] Step S41: The controller requests the braking system to decelerate, issue a warning message, and request EPB parking.

[0063] Step S42: The brake system increases the master cylinder pressure, applies brake pressure, and pulls up the EPB to park the vehicle.

[0064] Specifically, the braking system increases the master cylinder pressure through the Electronic Stability Control System (ESC), brakes to maintain pressure, and pulls up the EPB to park.

[0065] Step S43: Prompt warning information through the instrument.

[0066] The controller controls the instrument to remind the warning information. Specifically, the controller controls the instrument to remind the warning information in voice or text.

[0067] The method for suppressing accidental accelerator pedaling at low speeds provided in an embodiment of the present invention determines whether the starting accelerator pedaling accidental suppression conditions or the low-speed driving accelerator pedaling accidental suppression conditions are met based on obstacle information, accelerator pedal opening information and vehicle speed information; if so, the vehicle is controlled to brake to avoid collision, and a warning message is provided to the user to suppress accidental accelerator pedaling in low-speed scenarios, thereby avoiding vehicle collision losses and protecting the user's life and property safety; the ultrasonic radar is used to accurately sense obstacles near the vehicle in low-speed scenarios, and based on the accelerator pedal opening status, it is determined whether the user has made a mistake in operation, and emergency intervention is performed to avoid collision risks.
