Abstract

A control apparatus for a hybrid vehicle that includes front and rear wheels, a battery, a first driving source that drives one of the front and the rear wheels, a second driving source that drives the other of the front and the rear wheels, the second driving source being operated by an electric energy stored in an electricity storing unit, an electric motor that collects a kinetic energy during deceleration of the vehicle to charge the electricity storing unit, includes: a deceleration state detecting unit that detects a deceleration state of the vehicle; a turning state detecting unit that detects a turning state of the vehicle, wherein a regenerated power by the electric motor is calculated according to the deceleration state detected by the deceleration state detecting unit and the turning state detected by the turning state detecting unit, and the electric motor is controlled according to the regenerated power.

Claims

1. A control apparatus for a hybrid vehicle that comprises front and rear wheels, a battery, a first driving source that drives one of the front and the rear wheels, a second driving source that drives the other of the front and the rear wheels, the second driving source being operated by an electric energy stored in an electricity storing unit, an electric motor that collects a kinetic energy during deceleration of the vehicle to charge the electricity storing unit, comprising:

a deceleration state detecting unit that detects a deceleration state of the vehicle;

a turning state detecting unit that detects a turning state of the vehicle,

wherein a regenerated power by the electric motor is calculated according to the deceleration state detected by the deceleration state detecting unit and the turning state detected by the turning state detecting unit, and the electric motor is controlled according to the regenerated power.

2. A control apparatus for a hybrid vehicle according to claim 1, wherein the vehicle comprises a steering unit, wherein the turning state detecting unit comprises a steering angle detecting unit that detects a steering angle of the steering unit, and wherein the regenerated power by the electric motor is decreased as the steering angle detected by the steering angle detecting unit is increased to the direction to which the steering angle rotates.

3. A control apparatus for a hybrid vehicle according to claim 2, wherein the electric motor drives the rear wheels, and the regenerated power by the electric motor is set to zero when the steering angle detected by the steering angle detecting unit is increased to a predetermined value or greater.

4. A control apparatus for a hybrid vehicle according to claim 2, wherein when the steering angle is decreased after the regenerated power by the electric motor is decreased with an increase in the steering angle detected by the steering angle detecting unit, the regenerated power by the electric motor is set to a regenerated power at a maximum detected steering angle.

5. A control apparatus for a hybrid vehicle according to claim 4, wherein when the vehicle begins to travel straight ahead from a turn, the regenerated power by the electric motor is no more set to the regenerated power at the maximum detected steering angle.

6. A control apparatus for a hybrid vehicle according to claim 1, wherein the turning state detecting unit determines the turning state of the vehicle based on the steering angle and an operation direction of the steering unit and a yaw rate.
