摘要： An electric control apparatus for a four-wheel steering system is designed to calculate a rear wheel steering angle on a basis of a control rule corresponding with a steering mode selected from a plurality of rear wheel steering modes thereby to steer a set of dirigible rear road wheels at the calculated steering angle. The electric control apparatus is further designed to calculate a difference between new and old steering angles calculated when the selected steering mode has been changed to another one of the steering modes and immediately after change of the selected steering mode, to gradually decreasing an absolute value of the calculated difference at a predetermined time interval, to correct the new steering angle in accordance with the absolute value of the calculated difference until the absolute value becomes zero after change of the selected steering mode and to control an actual steering angle of the rear road wheels in accordance with the corrected new steering angle.

摘要： In an electric control apparatus for a four-wheel steering system including an electric motor the rotary angle of which is electrically controlled in accordance with a target steering angle of rear road wheels, and a hydro-mechanical tracer mechanism having a fluid control valve the valve element of which is drivingly connected to the electric motor to be displaced in proportion to the rotary angle of the electric motor, the tracer mechanism being arranged to steer the rear road wheels in proportion to a displacement amount of the valve element, the target steering angle is converted into a control value for rotation of the electric motor, and a drive signal indicative of the control value is applied to the electric motor. The electric control apparatus is designed to greatly change the control value to and from zero when the target steering angle is less than a predetermined small angle and to change the control value in proportion to the target steering angle when the target steering angle is more than the predetermined small angle.

摘要： In a hydraulic active suspension system, a plurality of actuators having working fluid chambers are provided corresponding to vehicle wheels. Each actuator is adapted to increase and decrease vehicle height as the results of the supply and the discharge of working fluid to and from its working fluid chamber, respectively. Supplying and discharging devices supply working fluid to and discharge from the working fluid chamber. Vehicle height sensors detect the vehicle heights at the locations corresponding to the vehicle wheels. A control device is further provided. The control device controls the supplying and discharging devices so that the pressure within the working fluid chamber in each actuator may be a value corresponding to the sum of a basic pressure determined according to the running conditions of the vehicle and a compensating pressure determined based upon the integral value of the difference between a standard vehicle height and an actual vehicle height. When the integral value of the difference is larger in magnitude than a predeterminate value, it is reduced in magnitude by the control device so as to prevent the control with the compensating pressure from overriding the control with the basic pressure.

摘要： A suspension controller is provided to effectively absorb a sporadic shock by appropriately altering a suspension characteristic. Especially, when a sporadic shock is detected, which is caused by riding-through a dip or riding-over a bump of the front wheels, the suspension controller of the invention can alter the rear suspension characteristic before the rear wheels ride through the dip or over the bump. The suspension controller of the invention particularly includes restoration means for restoring the altered suspension characteristic when a predetermined delay time interval has elapsed from a time point at which a vehicle height data was determined to be out of a predetermined range by determination means, and for starting the recount of the predetermined delay time interval if the vehicle height data is again determined to be out of the predetermined range by the determination means before the predetermined delay time interval elapses from the first determination.

摘要： According to the present invention, as soon as the sporadic protrusion or sinking of a road surface is detected at the front wheel of the vehicle during its running on the road surface, the air chambers of the air suspensions for the right and the left rear wheels of the vehicle are connected to each other to alter the spring constant of the rear suspensions to `soft` when the rear wheel passes over the sporadic protrusion or sinking of the road surface, so that the feel of ride of the vehicle and the controllability and stability thereof are kept good. After the rear wheel moves over the sporadic protrusion or sinking, the characteristic of the rear suspensions is returned to the original state appropriate to the normal running state of the vehicle. Detectors for the sporadic protrusion or sinking of the road surface may be provided for the right and the left front wheels of the vehicle, respectively. The rear suspensions of the vehicle can be more appropriately controlled by that.
