    摘要: A vehicle maneuvering control device is disclosed. A curve of a road is detected to calculate curve data including a distance between a vehicle and the curve, and a physical quantity indicating a degree of the curve. An allowable deceleration is set at which the vehicle can travel in accordance with conditions of the road. An allowable lateral acceleration is set at which the vehicle can travel in accordance with the conditions of the road. An allowable approaching speed is set at which the vehicle can approaches the curve based on the physical quantity and the lateral acceleration. A deceleration judging speed is calculated for judging whether a present speed at which the vehicle is traveling should be decreased based on the distance, the allowable deceleration and the allowable approaching speed. And, the present speed is decreased when it is higher than the deceleration judging speed.

    摘要: In a motor vehicle having a vehicle height adjusting device, wherein the height of each suspension is controlled so as to attain a set reference vehicle height, reaction forces of respective suspensions are detected and a difference between the detected reaction forces is calculated according to a formula, while the vehicle is stationary or is being driven straight. When the difference exceeds a predetermined value, it is determined that there are imbalances of the road surface contact loads of the wheels. Upon the determination of imbalances, the reference vehicle height is increased for some suspensions and decreased for other suspensions to eliminate the imbalances. The determination of imbalances is made when a value given by a formula including the integrated values for the suspensions exceeds a predetermined value, and then reference vehicle height is increased and decreased for the suspensions to eliminate the imbalances.

    摘要: An apparatus for adjusting height of a vehicle includes an incremental-type rotary encoder operated as a sensor for sensing the height of the vehicle. The incremental-type rotary encoder comprises a rotary disc having two sets of slits positioned at circumferential portions having different radii each other and different phase of 90.degree. in a rotating direction of the rotary disc. The incremental-type rotary encoder is further provided with a slit having a semi-circular shape disposed along a circumferential periphery thereof. A neutral position of an operation range of the rotary disc is determined as a boundary of the location of the semi-circular slit. The semi-circular slit is detected to discriminate whether height of the vehicle is above or below the neutral position of the rotary disc. A height adjusting mechanism is displaced in a vertical direction according to data from a detector. The apparatus controls the rotating direction and the amount of the rotation of the rotary disc.

    摘要: The present invention provides a vehicle dynamic control system which alters characteristics of respective vehicle movement controllers so that they can function properly against coming and foreseeable running conditions and current running conditions, recognizing beforehand details of an emerging curve on the road to be traveled. The system comprises a vehicle movement control alterant and at least one among vehicle movement controllers, i.e., a brake controller, a left/right wheel differential limiter controller and power distribution controller. When the vehicle is approaching the curve, the vehicle movement control alterant alters characteristics of a braking controller, the left/right wheel differential limiter controller and the power distribution controller to those favorable to turning for driving through a curve appropriately. When the vehicle is approaching the curve end, the alternate alters characteristics of the left/right differential controller to those favorable to stabilizing running so that the vehicle can pass the curve end and go into straight road appropriately.
