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.

Device for determining whether a motor vehicle is on an uphill road upon

An anti-slip control device for a drive wheel of a vehicle, for preventing an excessive amount of slip of the drive wheel during acceleration of the vehicle, by lowering a speed of the drive wheel when the amount of slip of the drive wheel exceeds a predetermined value. The control device includes a target-speed determining device for determining a target speed of the drive wheel based on a detected speed of the vehicle and the detected speed of the drive wheel. The control device further includes an uphill-road determining device for determining whether the vehicle is on an uphill road, and a low-speed detecting device for detecting that a detected running speed of the vehicle is lower than a predetermined threshold value. If the vehicle is on an uphill road and the vehicle speed is lower than the threshold value, the target speed determining device is operated in an uphill-road mode such that the determined target speed is lower than that determined in a flat-road mode.

Anti-slip control device for drive wheels of automotive vehicle

A control apparatus of a throttle valve in an internal combustion engine having a manually operable accelerator pedal. The control apparatus comprises a spring biasing the throttle valve in the opening direction, a first operating mechanism including an accelerator link mechanically connected to the accelerator pedal and a second operating mechanism including an electric motor. The first and second operating mechanisms can operate the throttle valve against the spring and independently of each other, the first operating mechanism thereby defining an upper limit of the degree of opening of the throttle valve in a predetermined relationship with the degree of depression of the accelerator pedal, and the second operating mechanism defining the degree of opening of the throttle valve within that upper limit.
