Abstract
A driving force control apparatus is provided to optimize the acceleration performance and improve the energy efficiency of a vehicle. Preferably, the front wheels are driven by the internal combustion engine, while the rear wheels are driven by the electric motor. The electric motor is driven by electrical power generated by the generator. The generator is driven by the engine. When acceleration slippage occurs in the front wheels, the generator is controlled so as to produce a generation load torque corresponding to the acceleration slippage magnitude.
Claims40
A driving force control apparatus for a vehicle having front and rear wheels with at least one of the front and rear wheels being a drive wheel driven by an internal combustion engine that drives a generator, said driving force control apparatus comprising:
- a drive wheel slippage estimating section configured to estimate if acceleration slippage is occurring in the drive wheel;
- and
- a generator control section configured to control a generation load torque of the generator to substantially correspond to an acceleration slippage magnitude of the drive wheel, when said drive wheel slippage estimating section estimates acceleration slippage occurring in the drive wheel.
A driving force control apparatus for a vehicle having front and rear wheels with at least one of the front and rear wheels being a drive wheel driven by an internal combustion engine that drives a generator, said driving force control apparatus comprising:
- drive wheel slippage estimating means for estimating if acceleration slippage is occurring in the drive wheel driven by the internal combustion engine;
- and
- generator control means for controlling a generation load torque of the generator to substantially correspond to an acceleration slippage magnitude of the drive wheel, when said drive wheel slippage estimating means estimates acceleration slippage occurring in the drive wheel.
