Abstract

The electric vehicle is an exciting object on which to apply "advanced motion control" technique. As an electric vehicle is driven by electric motors, it has three advantages: (1) motor torque generation is fast and accurate, (2) motors can be installed in 2 or 4 wheels, and (3) motor torque can be known precisely. These advantages enable us to easily realize (1) high performance antilock braking system (ABS) and traction control system (TCS) with minor feedback control at each wheel, (2) chassis motion control like direct yaw control (DYC), and (3) estimation of road surface condition. "UOT Electric March II" is our novel experimental EV with four in-wheel motors. This EV is made for intensive study of advanced motion control of an electric vehicle, which can be firstly realized by electric vehicle
