Document Type and Number:
Japanese Patent JP2014133495
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve hill-climbing performance after a driving wheel on a first axle side slips and a motor to enter a motor lock state, and the driving wheel recovers from the slip thereafter.SOLUTION: If a front wheel slips when a rear wheel-side motor enters a motor lock state, a power supply time ts which is shorter than when the front wheel does not slip is set, and a small decrease rate Rd is set (S150, S160). Then the motor is controlled so as to decrease in torque at a decrease rate Rd from the timing which is the power supply time ts after the motor enters the motor lock state. Consequently, the total driving force of the vehicle after the slip of the front wheel is removed can be made larger.
