<P>PROBLEM TO BE SOLVED: To provide a wheel-slip controller for preventing each driving wheel from being locked, by appropriately determining the locking tendency and then unlocking tendency of each driving wheel, when an electric vehicle is driven at a reduced speed. <P>SOLUTION: Upon detecting that the driving wheels (16, 18) are in the tendency of locking, on the basis of a wheel speed change rate (ΔVw) as a change rate of a wheel rotation speed (Vw) of the driving wheels (16, 18) and a slip rate (Sw) of the driving wheels (16, 18), a vehicle ECU (24) causes a motor (6) to work as a motor to impart driving torque of a motor (6) to the driving wheels (16, 18); and upon detecting that the locking tendency of the driving wheels (16, 18) is being reduced on the basis of the wheel speed change rate (ΔVw) and the slip rate (Sw), the vehicle ECU makes the motor (6) work as a generator and impart a regenerative braking torque of the motor (6) to the driving wheels (16, 18). <P>COPYRIGHT: (C)2011,JPO&INPIT |
