Title:
THREE-MOTOR ELECTRIC VEHICLE COMPOSITE BRAKE CONTROL METHOD AND APPARATUS, DEVICE AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/016859
Kind Code:
A1
Abstract:
A three-motor electric vehicle composite brake control method, comprising: determining a current brake pedal stroke of an electric vehicle; determining an electric braking force and a hydraulic braking force of the electric vehicle according to the brake pedal stroke, a total braking demand curve of the electric vehicle and a first pedal braking characteristic curve; proportionally distributing the hydraulic braking force to front wheels and rear wheels of the electric vehicle according to a first distribution rule; and distributing all of the electric braking force to the rear wheels of the electric vehicle according to a second distribution rule. A three-motor electric vehicle composite brake control apparatus is further comprised. An electronic device for executing the three-motor electric vehicle composite brake control method is further comprised. A medium for executing the three-motor electric vehicle composite brake control method is further comprised. According to the three-motor electric vehicle composite brake control method and device, and the electronic device and medium for executing the three-motor electric vehicle composite brake control method, the recovery efficiency of braking energy is increased to the maximum extent while ensuring the stable operation of the vehicle.
