Description

Vehicle control method, device, vehicle, storage medium, and program product Technical Field The present application relates to the field of vehicle technologies, and in particular, to a vehicle control method, a device, a vehicle, a storage medium, and a program product. Background With the improvement of the electric and intelligent levels of the automobile, the power and the dynamic response speed of the driving system of the automobile are obviously enhanced. The accelerator pedal is used as a central control input of the vehicle, and the functional safety of the accelerator pedal directly relates to the safety of the vehicle. Any unintended acceleration or abnormal stall due to an error in the accelerator pedal signal may cause a serious safety accident. Hardware redundancy design is currently commonly adopted to improve vehicle safety. Specifically, the accelerator pedal sensor is typically equipped with two separate signal acquisition circuits, including a separate power supply, a sensing unit, and a signal transmission path. When one of the signals fails due to hardware faults such as circuit breaking, ground short circuit and the like, the system can be automatically switched to the other normal signal, so that the basic acceleration control function is maintained. However, the above-described method cannot cope with a complicated failure mode such as a short power supply. For example, in the case where one signal continues to output a high level due to a short power failure and the other signal is normal, simple signal switching logic may erroneously determine a failed high level as a valid driving instruction, resulting in unintended acceleration of the vehicle, constituting a significant safety hazard. Therefore, there is a need for a vehicle control scheme to improve vehicle safety in complex failure modes. Disclosure of Invention Embodiments of the present application provide a vehicle control method, apparatus, vehicle, computer-readable storage medium, and computer program product, capable of avoiding unexpected acceleration that may be caused by directly switching signals and blindly trusting an effective signal at a fault moment, thereby improving vehicle safety in complex fault modes such as a short power supply.

In one possible implementation manner, the determining the control state of the accelerator pedal by the driver based on the magnitude relation between the third voltage currently corresponding to the effective signal and the voltage threshold includes: determining the control state as the driver releasing the accelerator pedal in the case where the third voltage is less than or equal to the voltage threshold; And determining the control state as the driver does not release the accelerator pedal when the third voltage is greater than the voltage threshold. In one possible implementation, after the determining the control state of the accelerator pedal by the driver, the method further includes: and setting the opening degree of the accelerator pedal to a first value under the condition that the control state is that the driver does not release the accelerator pedal, and returning to execute the magnitude relation between the third voltage currently corresponding to the effective signal and the voltage threshold value to determine the control state of the accelerator pedal by the driver until the control state is that the driver releases the accelerator pedal, wherein the first value is used for interrupting the power output of the vehicle. In one possible implementation manner, the obtaining, based on the valid signal, the target opening degree generated by the driver pressing the accelerator pedal again when the control state is that the driver releases the accelerator pedal includes: Acquiring a fourth voltage generated by the driver pressing the accelerator pedal again based on the effective signal when the control
