摘要: 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.

摘要: 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.

摘要: A method of controlling an automotive vehicle is disclosed whereby a steering characteristic of the vehicle is automatically adjustable to a feature of the driver's steering the vehicle. The feature of the driver's steering the vehicle is detected in terms of a driver's technique or habit in manipulating a steering wheel or a motion characteristic of the vehicle such as a yaw rate or a lateral acceleration resulting from a driver's manipulating the steering wheel. A pair of steerable road wheels, such as a pair of front road wheels, are steered through an angle which is proportioned to an angle through which the steering wheel is manually turned at a ratio which is variable with variation in the feature of the driver's steering the vehicle.

摘要: A swing arm suspension for automotive vehicle has a suspension arm pivotably connected to a suspension member for rotation about a substantially horizontal pivot axis. A lateral rod is connected to the suspension arm at one end thereof via a bushing and to a suspension member at the other end via another bushing. The position where the lateral rod is connected to the suspension member and to the vehicle body are offset from the pivot axis of the suspension arm. The position is chosen such that the lateral rod serves to provide roll compensating force for the suspension to satisfactorily and successfully restrict roll or compliance steering effects in the toe-out direction and to prevent positive camber. The lateral rod is adapted to be connected to the suspension member at such a position as to cause toe-in and/or negative camber.
