Abstract
There is provided a control device for vehicles which can improve quietness and fuel economy, while maintaining high responsiveness to acceleration of a vehicle. Therefore, the control device 100 for vehicles includes a gear ratio control unit 10 that controls a gear ratio of a vehicle V, and a determination unit 20 that determines whether or not there is an acceleration limit of the vehicle V. The gear ratio control unit 10 is configured to limit an increase in gear ratio Rt, when the determination unit 20 determines that there is an acceleration limit.
Claims14
A control device for vehicles that is mounted on a vehicle,
- the control device comprising:
- a gear ratio control unit that controls a gear ratio of the vehicle;
- a prediction unit that predicts acceleration of the vehicle;
- and
- a determination unit that determines whether or not there is an acceleration limit of the vehicle,
- wherein the gear ratio control unit limits an increase in the gear ratio, when the determination unit determines that there is an acceleration limit, and
- wherein the gear ratio control unit increases the gear ratio, when the prediction unit predicts acceleration of the vehicle and the determination unit determines that there is no acceleration limit.
A control device for vehicles that is mounted on a vehicle, the control device comprising:
- a gear ratio control unit that controls a gear ratio of the vehicle;
- a determination unit that determines whether or not there is an acceleration limit of the vehicle;
- and
- an engine control unit that controls a rotational speed of an engine of the vehicle,
- wherein the gear ratio control unit limits an increase in the gear ratio, when the determination unit determines that there is an acceleration limit, and
- wherein the engine control unit controls the rotational speed of the engine to be equal to or lower than a preset setting rotational speed, until the determination unit switches the determination that there is an acceleration limit to the determination that there is no acceleration limit, and the gear ratio control unit increases the gear ratio.
