US 2025/0026206 A1 · METHOD FOR CONTROLLING ELECTRIC VEHICLE

Abstract

A method for controlling an electric vehicle may include receiving driving information including a requested driving torque, a requested braking torque, and a steering angle of a driver, from a detection unit, distributing a driving torque or a braking torque to a left wheel and a right wheel of the vehicle based on a predetermined reference yaw moment, to follow the requested driving torque or the requested braking torque, determining whether a vehicle state is a braking state, distributing a driving torque to a front wheel and a rear wheel of the vehicle according to an optimal total power loss curve minimizing a power loss of the vehicle, when the vehicle state is a driving state, and distributing a braking torque to the front wheel and the rear wheel by comparing a minimum tire slip curve and an ideal braking force distribution curve, when the vehicle state is the braking state.
