Abstract
A wheel slip controlling apparatus uses a temperature assuming apparatus to assume a temperature of a brake pad by calculating an increase in temperature of the brake pad due to regular braking operations and braking operations performed for controlling an acceleration slip of a driving wheel. An increase in temperature of a brake pad due to normal braking operations is calculated. This increase in temperature responds to braking deceleration. An increase in temperature of the brake pad due to a braking operation for controlling the acceleration slip of the driving wheel is calculated. This increase in temperature responds to a braking force and a rotational speed of the driving speed. A decrease in temperature of the brake pad when a braking operation is not performed is calculated. This decrease in temperature responds to a rotational speed of the driving wheel. A temperature of the brake pad is assumed in accordance with determinations of vehicle operations. A braking operation is controlled to reduce an acceleration slip of a driving wheel during acceleration in accordance with the assumed temperature of the brake pad.
