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.

11. 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 driving force for driving a vehicle actually generated in accordance with a driving operation performed by a driver; a threshold value setting portion configured to set a threshold value of the driving force based on the vehicle speed detected by the vehicle speed detection portion; and a driving force information informing portion 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, wherein the driving force estimation portion is adapted to estimate not-yet-generated driving force before the driving force is actually generated. - View Dependent Claims (12, 13, 15, 17, 18, 19)

20. A method for evaluating a driving condition of a vehicle, the method comprising:
-
detecting an accelerator opening and a vehicle speed; estimating actually generated driving force that makes the vehicle advance forward based on the accelerator opening; setting a threshold value based on the vehicle speed; comparing the estimated driving force with the set threshold value; informing a driver of a relationship between the estimated driving force and the set threshold value; and estimating not-yet-generated driving force before the driving force is actually generated.
