The invention discloses a steering wheel assistance intelligent control method and system based on the vehicle speed. The method comprises the steps that the real-time vehicle speed V is obtained; according to the speed interval where the real-time vehicle speed V is located, the value of power-assisted steering F is set; whether the duration t of the real-time vehicle speed V in the same speed interval is larger than a time threshold t1 or not is judged, and if yes, the next step is executed; if not, returning to execute the step of acquiring the real-time vehicle speed V; and the absolute value of the difference value before and after the steering assistance is set, so that the steering assistance is changed to the set steering assistance F within the set time. Different steering assistance can be matched according to the vehicle speed when the vehicle runs, it is guaranteed that the vehicle has good driving comfort at different vehicle speeds, and traffic accidents are avoided.
本发明公开了一种基于车速的方向盘助力智能控制方法及系统,包括:获取实时车速V;根据实时车速V所处的速度区间,设定转向助力F的取值;判断实时车速V处在同一个速度区间内的持续时间t是否大于时间阈值t1,若是,则进入下一步;若否,则返回执行获取实时车速V的步骤;根据转向助力设定前后差值的绝对值,使得转向助力以设定的时间变化到设定的转向助力F。本发明能够根据车辆行驶时的车速匹配不同的转向助力,保证车辆在不同车速时都拥有很好的驾驶舒适性,避免了交通事故的发生。
