Due to the space limitation on the driving tire, small electric vehicles employed mechanical braking system rather than hydraulic braking system. For the same reason, anti-lock braking system (ABS) which is a basic skid control method is difficult to install on the driving tire. Although the mechanical braking system is compact, the rigidness and the response performance of the mechanical braking system is lower than hydraulic braking system. During braking on an icy road or in an emergency braking, the possibility of an accident is increased. To improve the safety and stability of the small electric vehicle, our past research has done a simulation model of hydraulic-mechanical hybrid brake system with ABS and regenerative brake control. The simulation result shows that ABS and regenerative brake control can prevent tire locked during braking on an icy road. To validate the simulation result, in this paper, we present the experimental method to control the motor on the slip condition. The experimental result shows that the skidding phenomenon can be prevented by controlling the rotation speed of the motor.
