Abstract

The present invention provides a driving force control unit for a vehicle having an accelerator opening degree detecting unit for detecting accelerator opening degree, a driving condition detecting unit for detecting engine driving condition, a driving force setting unit for setting a driving force indication value according to a plurality of different driving force characteristics based on the accelerator opening degree and the engine driving condition, a selector for selecting a driving force characteristic from the plural of different driving force characteristics by manipulation. The driving force setting unit setting the driving force indication value according to the selected driving force characteristic.

Claims

1. A driving force control unit for a vehicle, comprising;

an accelerator opening degree detecting unit for detecting accelerator opening degree;

a driving condition detecting unit for detecting engine driving condition;

a driving force setting unit for setting a driving force indication value according to a plurality of different driving force characteristics based on said accelerator opening degree and said engine driving condition; and

a selector for selecting a driving force characteristic from said plural of different driving force characteristics by manipulation,

wherein said driving force setting unit setting said driving force indication value according to said selected driving force characteristic.

2. The driving force control unit according to claim 1, wherein

said driving force setting unit memorizes a plurality of mode maps, said each of mode maps having a different driving force indication value based on said accelerator pedal opening degree and said engine operating condition,

said selector selects one mode map from said plurality of mode maps by manipulation, and

said driving force setting unit sets said driving force according to said selected mode map.

3. The driving force control unit according to claim 1,

said engine operating conditions includes engine rotational speed speed.

4. The driving force control unit according to claim 2,

said driving force setting unit includes first and second mode maps,

said first mode map has a normal driving characteristic suitable for normal driving,

said second mode map has a suppressed driving force characteristic.

5. The driving force control unit according to claim 2,

said driving force setting unit includes first, second and third mode maps,

said first mode map has a normal driving characteristic suitable for normal driving,

said second mode map has a suppressed driving force characteristic, and

said third mode maps has a emphasizing driving force characteristic.

6. The driving force control unit according to claim 2, further comprising:

a temporary change over switch for changing the mode map to another mode map temporarily.

7. The driving force control unit according to claim 2, further comprising;

a display provided to the instrument panel,

said driving force setting unit controls said display so as to display a characteristic line for driving force and change said characteristic line according to the operation of the accelerator pedal.
