Method for preventing accelerator from being mistakenly and suddenly stepped on for pure electric light truck

Abstract

The invention discloses a method for preventing an accelerator from being mistakenly and suddenly stepped on for a pure electric light truck. The method comprises the following steps that S1, a VCU judges whether the gear of the whole truck is a reverse gear or a forward gear; s2, if the gear of the whole vehicle is the reverse gear and meets the conditions at the same time, it is judged that the accelerator is mistakenly stepped on, a VCU does not send a torque request signal to an MCU, torque output is forbidden, the VCU sends an accelerator mistakenly stepped signal to an ICM through TBOX, and the ICM gives an accelerator mistakenly stepped on prompt; s3, if the gear of the whole vehicle is a forward gear, firstly, the VCU judges whether the whole vehicle is located on a ramp through the MCU, if yes, torque output suppression is not carried out, if not and conditions are met at the same time, it is judged that the accelerator is mistakenly and suddenly stepped, the VCU sends the suppressed torque and torque loading rate to the MCU, acceleration suppression is carried out, the VCU sends an accelerator mistakenly and suddenly stepped signal to the ICM through the TBOX, and the ICM gives an accelerator mistakenly and suddenly stepped prompt; when the vehicle speed is larger than a third set vehicle speed threshold value or smaller than the third set vehicle speed threshold value and the accelerator depth is smaller than a second set accelerator threshold value, acceleration suppression is quitted; according to the method, the driving safety of the driver is well guaranteed.
