Abstract
In recent years, electric vehicles have come to be widely used. The braking force of electric vehicle is the sum of mechanical brake force and regenerative brake force. The mechanical brake force is proportional to the treadless force on the brake pedal. On the other hand, the regenerative brake force produced by the driving motor. The regenerative brake force with the braking conditions, for example, the degree of deceleration, rotation speed of tires, body speed and charging level of the battery. Then it is important for the stability of the electric vehicle in braking motion that the actual brake force distribution decided by the mechanical brake force and the regenerative brake force are maintained in the front tire lock region. In this report, the effect of ABS is researched when the road surface condition is different in a right and left tires. The further more effects of ABS and regenerative brake force on a stability of a small electric vehicle in braking motion are clarified.
