Control system and method for preventing reversing of blade electric vehicle during starting

Abstract

The invention provides a control method for preventing reversing of a blade electric vehicle during starting. The method comprises the following steps that if the electric blade vehicle is started and is in a forward gear and when a motor is in the negative rotating speed, a whole vehicle controller detects the state of the electric vehicle, and if the state of the electric vehicle meets the stall condition, the whole vehicle controller sends a signal to a motor controller to request the motor controller to carry out control of the zero rotating speed, the motor rotating speed is kept at zero, and the vehicle is kept still; and if not, a voice prompting system is started, and a driver is reminded to pay attention to driving. The invention further provides a control system for preventing reversing of the blade electric vehicle during starting. Driving of a user is facilitated, and the starting safety is guaranteed.

Description

technical field [0001] The invention relates to a control method and system for anti-reversing when starting a pure electric vehicle. Background technique [0002] At present, pure electric vehicles use motors to drive the vehicle forward. When parking on a ramp, it needs to be assisted by a handbrake to prevent the vehicle from going backwards. It is difficult to drive and has potential safety hazards. The disadvantages of the existing technology are: [0003] 1. When an electric vehicle starts on a slope, it takes a certain amount of time for the accelerator signal to be input to the motor torque output, so the driver is required to use the handbrake to assist the start. When the operation is not stopped, the vehicle is prone to reverse, which poses a safety hazard; [0004] 2. Frequent use of the handbrake to assist starting will not only easily cause the brake pads to wear and heat, but also waste electric energy. Contents of the invention [0005] The technical probl...
