    • A wheeled vehicle is equipped with a feedforward steering control system which steers the vehicle through front or rear road wheels in accordance with a driver's steering input such as an angular displacement of a steering wheel, and a negative feedback system which senses a turning behavior of the vehicle such as a yaw rate or a lateral acceleration, and steers the vehicle through the front or rear wheels in such a negative direction as to reduce the turning behavior. The feedforward system may control the angular direction of the front or rear wheels in accordance with a linear combination of the steering input and the time derivative of the steering input, or may control the angular directions of both of the front and rear wheels in accordance with different transfer functions between the steering input and the front and rear wheel angles. The negative feedback system is combined with the feedforward system in various ways to provide desired characteristics of the turning behavior. The negative feedback quantity determined by the negative feedback system may be proportional to the sensed turning behavior, or may be determined in accordance with the difference between the sensed turning behavior, and the reference turning behavior calculated from the vehicle speed and steering input.
    • 轮式车辆配备有前馈转向控制系统,其根据驾驶员的转向输入(例如方向盘的角位移)和负反馈系统,通过前车轮或后车轮转向车辆,以及负反馈系统,其感测车轮的转向行为 车辆,例如偏航率或横向加速度,并且以如此减小转弯行为的方向使车辆通过前轮或后轮。 前馈系统可以根据转向输入和转向输入的时间导数的线性组合来控制前轮或后轮的角度方向,或者可以根据转向输入的时间导数来控制前轮和后轮的角度方向 转向输入与前轮和后轮之间的转换功能不同。 负反馈系统与前馈系统以各种方式结合,以提供所需的转向特性。 由负反馈系统确定的负反馈量可以与感测到的转向行为成比例,或者可以根据感测到的转向行为与根据车速和转向输入计算的参考转弯行为之间的差来确定。

    • An automatic vehicle height-adjusting system is applied to a vehicle including a sprung mass and an unsprung mass in contact with a road surface, the sprung mass being supported on the unsprung mass via a spring or the like. The system includes a sensor, which senses the distance between the sprung mass and the road surface and generates a distance signal indicative thereof. In response to the distance signal, a first discriminator or comparator determines whether or not the distance is less than a first predetermined value, and generates a first comparison signal indicative thereof. In response to the distance signal, a second discriminator or comparator determines whether or not the distance is greater than a second predetermined value, and generates a second comparison signal indicative thereof. The second predetermined value is chosen to be greater than the first predetermined value. In response to the first and second comparison signals, a control mechanism increases the height of the sprung mass with respect to the unsprung mass when the distance is less than the first predetermined value, and decreases the height of the sprung mass with respect to the unsprung mass when the distance is greater than the second predetermined value.
    • 将自动车高调整系统应用于包括与路面接触的悬挂质量和簧下质量的车辆,簧簧通过弹簧等支撑在簧下的质量上。 该系统包括感测弹簧质量与路面之间的距离的传感器,并产生指示其的距离信号。 响应于距离信号,第一鉴别器或比较器确定距离是否小于第一预定值,并产生指示其的第一比较信号。 响应于距离信号,第二鉴别器或比较器确定距离是否大于第二预定值,并且产生指示其的第二比较信号。 第二预定值被选择为大于第一预定值。 响应于第一和第二比较信号,当距离小于第一预定值时,控制机构增加悬挂质量相对于簧下质量的高度,并且减小簧上质量相对于簧下的高度 当距离大于第二预定值时。
