Abstract
A driving condition evaluation device is provided. The device includes a vehicle speed detection portion configured to detect a vehicle speed. A driving force estimation portion is configured to estimate driving force for driving a vehicle generated in accordance with a driving operation performed by a driver. A threshold value setting portion is configured to set a threshold value of the driving force based on the vehicle speed detected by the vehicle speed detection portion. A driving force information informing portion is configured to inform the driver of a relationship between the driving force estimated by the driving force estimation portion and the threshold value set by the threshold value setting portion.
Claims10
A driving condition evaluation device comprising:
- a vehicle speed detection portion configured to detect a vehicle speed;
- a driving force estimation portion configured to estimate a not-yet-generated driving force for driving a vehicle generated in accordance with an accelerator opening before a driving force is actually generated;
- a threshold value setting portion configured to set a threshold value of the not-yet-generated driving force based on the vehicle speed detected by the vehicle speed detection portion;
- and
- a driving force information informing portion configured to inform a driver before the driving force is actually generated of a relationship between the not-yet-generated driving force estimated by the driving force estimation portion and the threshold value set by the threshold value setting portion.
A method for evaluating a driving condition of a vehicle, the method comprising:
- detecting a vehicle speed;
- estimating a not-yet-generated driving force for driving a vehicle in accordance with an accelerator opening before a driving force is actually generated;
- setting a threshold value of the not-yet-generated driving force based on the detected vehicle speed;
- and
- informing a driver before the driving force is actually generated of a relationship between the estimated not-yet-generated driving force and the set threshold value.
