Abstract

An eAWD(Electronic All-Wheel Drive) system is a powertrain structure with engine for front-wheel drive and twin motor unit for rear-wheel drive. In this paper, wheel-slip based control is used to improve traction and braking of vehicle, utilizing the characteristic of eAWD powertrain. When over-slip or steering event occur, target wheel speed is generated based on target wheel slip and steering wheel angle. Target torque is calculated from sliding mode controller. The torque is converted into proper value considering actuator characteristic. The proposed algorithm is verified in various road condition scenarios by using commercial simulation software CarMaker and MATLAB/Simulink.
