Abstract
A vehicle speed is determined from a detected signal, e.g., pulses produced by a rotation sensor for detecting rotation of the output shaft of a transmission, which signal corresponds to rotation of road wheels. Then, the deceleration of the vehicle speed is calculated from the detected vehicle speed, and then a rate of change of the deceleration is calculated from the calculated deceleration. If the rate of change of the deceleration is larger than a predetermined value, thereby indicating a panic braking condition of the vehicle, an automatic clutch incorporated in the transmission is disengaged to prevent stalling of the vehicle engine.
