IPC: B60L50/16
Filed: 2000-07-06
Abstract: PROBLEM TO BE SOLVED: To provide a control device for a front- and rear-wheel-drive vehicle capable of suitably suppressing the gear-changing shock even when the inertia of a first prime mover is different. SOLUTION: When the change of the working condition of the prime mover, for example, the change between the two-wheel-drive condition and the four- wheel-drive condition is judged by a prime mover working condition change judging means, the change transition time T0 of the prime mover working condition is set by a change switching means to be the longer as the inertia of the first prime mover comprising an engine 14 and an MG 16 becomes the larger. For example, the output torque change period of a RMG 70 functioning as a second prime mover is prolonged adaptable to the first prime mover with the prolonged output torque change period due to the large inertia, the deviation in the torque increasing/decreasing speed of the front and rear wheels in the change transition period T0 is reduced, and the changing shock is suitably suppressed.
