Abstract

The invention provides a braking control method and device and an electric vehicle. The braking control method comprises the following steps: obtaining a braking mode when a vehicle is braked and a working state of an anti-lock braking system of the vehicle; switching a braking mode of the vehicle to hydraulic braking when the braking mode of the vehicle is electric braking and the working state of the anti-lock braking system is an activated state, maintaining the working state of the anti-lock braking system as an activated state, and braking the vehicle through the anti-lock braking system.The method switches the braking mode to the hydraulic braking when the vehicle is in the electric braking and the anti-lock braking system is in the activated state, thereby avoiding the problems that the braking distance is increased and the braking is instable due to the direct withdrawal of the electric braking.

Description

technical field [0001] The invention relates to the field of electric vehicle braking, in particular to a braking control method and device and an electric vehicle. Background technique [0002] With the increasing number of vehicles, the environmental pollution caused by vehicle exhaust is also becoming more and more serious. In order to reduce the pollution of vehicles to the environment, the application of electric vehicles has become more and more extensive. The anti-lock braking system is a safety braking system that is installed on most electric vehicles at present. It is used to automatically control the braking force when the electric vehicle brakes to prevent the wheels from locking. [0003] Generally, if an electric vehicle activates the anti-lock braking system under the electric braking state, it generally adopts the method of directly exiting the electric braking to solve the instability of the braking system caused by excessive electric braking.
