자동차의 제어성 개선 방법은 바퀴 슬립 제어기의 도움으로 결정되고 조정되는 소망 슬립 값을 기재하고 있다. 아래의 값이 측정되며; 편요률(φ) 스티어링값(δ) 바퀴 속도(V) 입구 압력 혹은 바퀴 브레이크 압력 엔진속도 드로롤 밸브값 아래의 값이 평가된다; 횡방향 차량 속도(V) 횡방향 차량 가속도(V) 바퀴 슬림값(λ) 횡방향 힘(F) 타이어 힘(F) 종방향 속도(V) 소망 슬립값(λ)은 간단한 차량 모델의 도움으로 이들로부터 결정된다. PROBLEM TO BE SOLVED: To improve running stability and vehicle maneuverability by high order running maneuverability control when driving force and braking force are simultaneously controlled. SOLUTION: The improvement method of maneuverability of automobile is provided, and a target value of slip is calculated and controlled by using a wheel control unit. Variables to be measured are: yaw speed ψ', steering angle δ, wheel speed VRi , supply pressure or wheel brake pressure, engine speed, and throttle valve angle. Variables to be estimated are: longitudinal speed of the vehicle VX, longitudinal acceleration of the vehicle VX', wheel sliding value λ1 , longitudinal force FB, tire force FR, and side direction speed VY. he target value λ(i) * can be calculated with these values by using a simple vehicle model.
