Abstract
A hybrid vehicle capable of efficiently regenerating a battery when the driving route is previously defined and of decreasing exhaust gases. A controller calculates a battery stored residual charge from the output of a battery current voltage detection sensor, sets a target value for the battery residual charge in accordance with road information and information of the present location of the vehicle, received from a navigation processor, and adjusts the outputs of a motor and an engine to cause the actual battery residual charge to approach the target value.
Claims7
A hybrid vehicle, comprising:
- a motor;
- an internal-combustion engine;
- storage means for transferring electric power by supplying power to drive said motor and by receiving electric power generated by said motor;
- storage residual charge detection means for detecting a residual charge of said storage means;
- present location detection means for detecting a present location of the vehicle;
- memory means for memorizing road information including energy information related to residual charge required for the storage means at previously defined points on a driving route;
- target value setting means for setting a target value for the residual charge of said storage means at one of said previously defined points ahead of the detected present location based on said energy information stored in said memory means and the present location detected by the present location detection means;
- and
- output adjustment means for adjusting outputs of said motor and said engine to bring the residual charge of said storage means to the target value upon reaching said one previously defined point.
