US 2026/0264651 A1 · CONTROL METHOD AND APPARATUS

Abstract

A control method is provided, and includes: obtaining an electric regenerative braking torque of a front axle and an electric regenerative braking torque of a rear axle of a vehicle, where a ratio of the electric regenerative braking torque of the front axle to the electric regenerative braking torque of the rear axle is less than a preset distribution ratio; when hydraulic braking torque compensation is triggered, determining a hydraulic braking torque of the front axle based on the electric regenerative braking torque of the front axle and a braking torque determined based on the electric regenerative braking torque of the rear axle and the preset distribution ratio; and controlling, based on the hydraulic braking torque of the front axle, a hydraulic brake of the front axle to work. The control method avoids premature triggering of an EBD function in a vehicle braking process.
