Problems solved by technology

This method considers the opening of the accelerator pedal and the brake pedal and controls the energy feedback in combination with the vehicle speed. However, during driving, the opening of the pedal alone cannot accurately reflect the driver's driving intention, and cannot provide the driver with Personal energy feedback mode selection
[0005] That is to say, the current relevant capacity feedback methods mainly have the following disadvantages: if the vehicl

Abstract

The invention provides a vehicle control method and system and a vehicle. The vehicle control method comprises the following steps that when the vehicle meets the energy feedback condition, the vehicle speed and the brake pedal state are monitored; if the vehicle speed is higher than the first preset vehicle speed, the brake pedal opening degree and the brake pedal opening degree change rate are determined according to the brake pedal state; the brake feedback coefficient is determined according to the vehicle speed, the brake pedal opening degree and the brake pedal opening degree change rate; and the brake feedback torque is obtained according to the brake feedback coefficient and the maximum feedback power of a motor, and energy feedback is conducted according to the brake feedback torque. Through the vehicle control method, a personalized energy feedback mode selection can be provided for a driver, accordingly, energy feedback of the vehicle is more reasonable, and meanwhile, the energy feedback effect is improved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a vehicle control method, a control system and the vehicle. Background technique [0002] With the gradual upgrade of energy saving and emission reduction requirements, the braking energy feedback function is becoming more and more important in pure electric vehicles or hybrid vehicles. The energy feedback function should adjust the feedback state and feedback torque in real time according to the working state of the vehicle on the premise of ensuring the driving safety of the vehicle. [0003] Despite the rapid development of technology today, battery technology is still the biggest bottleneck restricting the development of pure electric vehicles, unable to meet the battery life requirements of users. If the energy recovery efficiency can be maximized, it is of great significance for extending the cruising range of pure electric vehicles. At the same time, it ...
