PROBLEM TO BE SOLVED: To provide a reduction gear capable of carrying out proper vehicle behavior control while solving the problem of making a driver feel a sense of incongruity by suddenly reducing speed as a deviation occurs on target car speed and actual car speed and automatic speed reduction equivalent to the deviation is applied in releasing operation of an acceleration pedal in turning, etc. SOLUTION: A target yaw rate is computed from yaw rate detection output, a lateral acceleration limiting value depending on car speed limiting from an acceleration detection value and a car speed detection value, the target car speed is computed from a target lateral acceleration limiting value, a target lateral is computed, target car speed is computed from the target lateral acceleration value and a target yaw rate value, target speed reduction is computed from this target car speed, target brake pressure is computed in accordance with this computed result, target engine torque is computed in accordance with the target deceleration value, target brake pressure computation is changed in accordance with the acceleration detection value, and a rising or lowering degree of the target brake pressure is limited.
