Vehicle drive system |
摘要 |
An object of the present invention is to provide a vehicle drive system that is capable of appropriately continuing four-wheel drive according to driver's intention and road conditions. The vehicle drive system includes a motor 5 which drives rear wheels 15R and 15L, and a 4WDCU 6 for controlling the electric energy inputted to the motor to control the motor drive. When the driver issues a request command for continuing four-wheel drive or when the road condition of the vehicle changes, a control logic 200 of the 4WDCU 6 continues a four-wheel drive mode in which the rear wheels are driven by the motor 5 and the front wheels by an internal combustion engine 1. |
