Abstract:
A drive force control system for vehicles, comprising:an engine, a generator connected to the engine, a front wheel drive motor and rear wheel drive motor which are supplied power from the generator, and a microprocessor programmed to: compute a target drive force of the vehicle based on an accelerator depression amount and vehicle speed, compute a target front wheel drive force and a target rear wheel drive force by dividing the target vehicle drive force, compute a power required to drive the generator based on the target vehicle drive force, compute the target rotation speed of the generator based on the power required to drive the generator and vehicle speed, compute a target torque of the engine based on the power required to drive the generator and rotation speed of the generator, control the front wheel drive motor and rear wheel drive motor based on the target front wheel drive force and target rear wheel drive force, and control the engine and generator based on the target engine torque and target generator rotation speed.
