Abstract

The invention provides a control method and system for remote driving of an electric vehicle. The method is applied to an entire vehicle controller of the electric vehicle. The control method comprises the following steps: obtaining a running state of each component of the electric vehicle when a remote driving function of the electric vehicle is judged to be in an on state; acquiring a first current vehicle speed when an electronic stability controller of the electric vehicle fails or at least one device of a hydraulic brake and an electronic caliper of the electric vehicle is in a faulty state; outputting a first control signal toa drive motor controller if the current speed is not zero, allowing the drive motor controller to control a drive motor to output the maximum braking torque, and outputting a second control signal to a parking gear controller when the vehicle speed is reduced to zero, and allowing the parking gear controller to control the parking gear parking mechanism to be locked. The braking redundancy control is provided, and the safety and reliability of the braking of remote driving of the vehicle are improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a control method and system for remote driving of electric vehicles. Background technique [0002] Remote driving refers to a driving mode in which the user controls the forward / backward / steering of the vehicle within a certain distance outside the vehicle by operating the remote control device. Since the driver is usually located outside the vehicle during remote control driving, he cannot control the driving of the vehicle in a timely manner. When the conventional brake fails, he cannot make an emergency stop by stepping on the brake pedal, which is prone to problems in the vehicle control system. Sometimes, especially when there is a problem with the braking and parking system of the vehicle in remote control driving, uncontrollable driving accidents will occur. Contents of the invention [0003] Embodiments of the present invention provide a control method and system f...
