Problems solved by technology

Drivers only decelerate through air pressure braking when driving traditional vehicles. Most drivers have no concept of electric braking when they start driving pure electric vehicles. They will brake in the same way as driving traditional vehicles. This system For pure electric buses, the brake force will be too large and the recovered braking energy will be reduced.

Embodiment Construction

[0027] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as figure 1 As shown, the system for assisting the driver in adapting to the brake control of pure electric vehicles in the present invention includes a brake pedal detection sensor, which detects the brake pedal opening and the rate of change of the brake pedal opening, and cooperates with the collected motor speed signal, through the vehicle The computer analyzes the above-mentioned three-way signals, outputs the analysis results to the display screen, evaluates and judges the driver's braking behavior in the form of graphics and voice prompts, guides the driver's driving behavior, and better controls the brakes through the motor. more braking energy back to the battery.

[0029] Such as figure 2 Shown is the flow chart of the method for assisting the driver to adapt to the braking control of the pure electric vehicle in the p...

Abstract

The invention discloses a method for assisting a driver to adapt to brake control of a battery electric vehicle. When the brake is performed, the signals of the openness of a brake pedal, the openness change rate of the brake pedal and the rotating speed of a motor are detected, the detection values of the three signals are compared with preset values, and evaluation results are output to prompt the driver to perform the improvement. When the driver, who is used to drive a traditional passenger car, drives a battery electric passenger car, the method can evaluate the braking behavior of the driver during the vehicle braking, guide the braking behavior of the driver, help the driver to adapt to driving of the vehicle as soon as possible, use the motor for braking to the greatest extent, and improve the recovery rate of braking energy.

Description

technical field [0001] The invention relates to a method for assisting a driver to adapt to braking control of a pure electric vehicle. Background technique [0002] Braking energy recovery is one of the important technologies of modern electric vehicles and hybrid vehicles, and it is also an important feature of them. In general internal combustion engine vehicles, when the vehicle decelerates and brakes, the kinetic energy of the vehicle is converted into heat energy through the braking system and released to the atmosphere. In electric vehicles and hybrid vehicles, this wasted motion energy can be converted into electrical energy through braking energy recovery technology and stored in the battery, and further converted into driving energy. [0003] Toyota's energy regenerative braking system is characterized by the coordinated control of braking energy recovery and hydraulic braking. The principle of coordinated braking is to first ensure the stability and safety of veh...
