Abstract
There are provided as drive sources an engine 2, a front motor 3 provided on a front wheels 8 side of the vehicle and a rear motor 4 provided on a rear wheels 9 side of the vehicle, and in executing a regeneration of deceleration energy when braking, a regeneration capacity of the front motor 3 and a regeneration capacity of the rear motor 4 are calculated, respectively, so that the regeneration is executed with either of these motors 3, 4 which can provide a larger regeneration capacity.
Claims6
A driving force control system for a hybrid vehicle, comprising:
- an engine,
- a primary electric motor,
- a secondary electric motor, wherein
- either front wheels or rear wheels are driven by the engine and the primary electric motor and the other of the front wheels and rear wheels are driven by the secondary electric motor, and
- in performing a regeneration of deceleration energy when braking, a regeneration capacity of the primary electric motor and a regeneration capacity of the secondary electric motor are calculated, respectively, so that the regeneration is performed with either of the electric motors which can provide a larger regeneration capacity;
- and
- a member for determining whether the primary electric motor or the secondary electric motor performs the regeneration based on the regeneration capacities of the primary and secondary electric motors.
A driving force control system for a hybrid vehicle comprising:
- an engine,
- a primary electric motor provided on a front wheel side of the vehicle,
- a transmission for transmitting driving force of the engine and the primary electric motor to front wheels of the vehicle,
- a secondary electric motor provided on a rear wheel side of the vehicle,
- a rear differential for connecting the secondary electric motor to rear wheels of the vehicle,
- regeneration possibility determination means for determining whether or not a regeneration in the primary electric motor and the secondary electric motor is possible,
- regeneration capability calculation means for calculating a regeneration capability of the primary electric motor and the secondary electric motor,
- regeneration capability comparing means for comparing the regeneration capability of the primary electric motor with the regeneration capability of the secondary electric motor, and
- regeneration executing means for making either of the electric motors which can provide a larger regeneration capability execute a regeneration.
