specific Embodiment 1

[0119] (1) The VCU (Vehicle Control Unit, vehicle controller) first conducts a self-check, and the self-check conditions include but are not limited to: the vehicle is in a power-on ready state, and there is no ABS (Anti-locked Braking System, anti-lock braking system) failure. , there is no ESC (Electronic Stability Control, electronic stability control system) fault, the value of the remote power-on signal sent by the BCM (body control module, body control system) is 1, and the VCU is allowed to respond to the ADAS (Advanced Driving Assistance System) if the above conditions are met. ), indicating that ADAS mode is available.

[0120] (2) The ACC (Adaptive Cruise Control) mode can be entered when the ADAS mode is available and the following conditions are met at the same time: (a) The driver has no intention to take over (the accelerator pedal is not depressed, and the brake pedal is not depressed). (b) No limp fault; (c) No speed fault; (d) No zero torque fault; (e) The veh...

Abstract

The invention discloses an auxiliary driving control method, a vehicle and a computer readable storage medium. The method comprises the steps that an auxiliary driving mode currently activated by an auxiliary driving system is determined; the auxiliary driving system is controlled to send a theoretical guide value corresponding to the auxiliary driving mode to a vehicle control unit; the vehicle control unit is controlled to receive the theoretical guide value, and target torque corresponding to the theoretical guide value is determined; and controlling a motor to rotate according to the target torque so as to guide the vehicle to run according to the theoretical guide value. According to the invention, the decision response speed of the auxiliary driving system is improved.

Description

technical field [0001] The present invention relates to the technical field of assisted driving, in particular to a control method for assisted driving, a vehicle and a computer-readable storage medium. Background technique [0002] In recent years, with the gradual increase in the configuration rate of the Advanced Driving Assistance System (ADAS) for electric vehicles, the current assisted driving control method for electric vehicles is: under the condition that the assisted driving system is activated, the electronic stability controller ( Electronic Stability Control, referred to as ESC) receives the speed, acceleration and other requests of the assisted driving system, and converts it into a torque request through calculation, and sends the torque request to the vehicle controller (Vehicle Control Unit, referred to as VCU), and the vehicle controller responds The torque request of the electronic stability controller is input to the motor controller, so that the motor co...
