Abstract
The device has a first detecting device for detecting a running speed of the vehicle, a second detecting device for detecting a specific point of time during a starting period of the vehicle, and a judging device for comparing the running speed of the vehicle detected by the first detecting device, with a predetermined threshold value, when the specific point of time is detected by the second detecting device. The judging device determines that the vehicle is on the uphill road, if the detected running speed is lower than the predetermined threshold value.
