Title:
ELECTRO-HYDRAULIC COMPOSITE BRAKING CONTROL METHOD AND SYSTEM FOR ELECTRIC VEHICLE, AND ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/045323
Kind Code:
A1
Abstract:
The present invention provides an electro-hydraulic composite braking control method and system for an electric vehicle, and an electric vehicle. The method comprises: acquiring a braking signal of a vehicle, and for the braking signal, obtaining different braking working conditions according to braking strength; according to the braking working conditions corresponding to the braking signal, distributing braking force to obtain a front axle braking control signal and a rear axle braking control signal; acquiring a motor working condition and battery working condition information; and according to the front axle braking control signal, the braking signal, the motor working condition, and the battery working condition information, acquiring a front axle regenerative braking control signal and a front axle hydraulic braking control signal. The present invention can achieve staged control of braking force distribution in an electro-hydraulic composite braking process, fully utilizes the regenerative braking of a motor, and can improve the recycling efficiency of battery energy while ensuring that the vehicle has enough braking efficiency.
