摘要： A traction control device in an engine which has an intake passage. A throttle valve and a flow control valve are arranged in series in the intake passage. Where acceleration of the motor vehicle is carried out, when the speed of rotation of the driven wheel or acceleration of the speed of rotation of the driven wheel exceeds a predetermined level, the flow control valve is closed. When the speed of rotation of the driven wheel becomes lower than a predetermined level or deceleration of the speed of rotation of the driven wheel becomes larger than a predetermined level, the flow control valve is opened.

摘要： A wheel slip controlling system is provided to immediately control the rotation of the drive wheels by controlling the output power of an internal combustion engine as well as by controlling the brake mechanism of the drive wheels when a slippage is detected during the process of braking or acceleration. The brake mechanism is an anti-skid control system which uses a pressure change-over valve to accurately control the braking force. The wheel slip controlling system also includes a second throttle valve responsive to a traction control mechanism for controlling the amount of intake air of the internal combustion engine such that the speed of the driven wheels can be slowed when slipping occurs.

摘要： A wheel slip controlling system according to the present invention comprises braking actuator operable by a driver of a car for braking rotation of wheels at least including driving wheels, slip detector for detecting a slipping condition of the wheels to output a slip signal indicative of the slipping condition, anti skid controller for receiving the slip signal and for controlling, in response to the slip signal received, the pressure to be imparted from the braking actuator with a self-contained pressure source to control braking slips of said wheels at least including the driving wheels and traction controller responsive to the slip signal during acceleration of the car for controlling the driving wheels with the self-contained pressure source for control acceleration slips at least of the driving wheels. Since the system makes use of the pressure of a hydraulic source of a conventional anti skid brake system and controls a braking system, quick responsiveness can be obtained without the necessity of extensive modification of the conventional anti skid brake system. When a driver carries out a braking operation to exhibit his own braking will, the braking operation will have a priority so that the slip control can be attained without deterioration of the treadling feeling of a brake pedal. If any other controlling technique such as priority of stabilized brake hydraulic pressure with a hysteresis is used in combination for selection of traction control, more stabilized acceleration slip control can be attained.

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.
