摘要： A slip determination system for a vehicle, which is capable of improving the determination accuracy by avoiding erroneous determination of excessive slip of wheels when a state of the wheels, driven/braked by motors, is switched. In the slip determination system according to the present invention, when first and second motor rotational speeds NMOT1 and NMOT2, which are rotational speeds of rear motors which brake/drive rear wheels WRL and WRR, reach a reference rotational speed NMREF set based on wheel rotational speeds NWFL, NWFR, NWRL, and NWRR, it is determined that excessive slip has occurred in the rear wheels WRL and WRR. When the sign of a target torque TROBJ of the rear motors is inverted, the reference rotational speed NMREF is changed to a value more difficult to be reached by the first and second motor rotational speeds NMOT1 and NMOT2, or the excessive slip determination is inhibited.

摘要： A vehicle driving system includes: a left wheel driving system having a first motor and a first speed changer; a right wheel driving system having a second motor and a second speed changer; a motor controller which controls the first motor and the second motor, a rotation restricting unit which can be shifted between a released state and an applied state; and a rotation restricting unit controller which controls the rotation restricting unit. When the rotation restricting unit controller shifts the rotation restricting unit from the applied state to the released state, the motor controller controls the first motor and the second motor so that a torque sum of the first motor and the second motor approaches zero while maintaining a torque difference between the first motor and the second motor.

摘要： A vehicle drive system, that can improve drive efficiency while maintaining vehicle stability, includes a step (S3, S105) in which a switch is made from 2WD to AWD on the basis of a cumulative slip point; a step (S12, S303) in which a switch is made from 2WD to AWD on the basis of a calculated lateral G; a step (S13, S109, S111) in which a switch is made from AWD to 2WD after the step (S3 or S105) under a first switching condition; and a step (S13, S306, S308) in which a switch is made from AWD to 2WD after the step (S12 or S303) under a second switching condition. The first switching condition and the second switching condition differ from one another.
