摘要： A vehicular power steering system has on/off control means for controlling a hydraulic fluid pump in accordance with steering effort applied on a steering wheel. On the other hand, a sensing means senses vehicle speed. Judging means is connected with the on/off control means and the vehicle speed sensing means, and produces an actuating signal when the control means produces a control signal to drive the fluid pump and at the same time the sensed vehicle speed is below a predetermined speed. A solenoid valve is connected with the judging means. The solenoid valve is arranged to open and close a bypass passage which allows an air fuel mixture to bypass a throttle valve for an intake air flow control of the engine. Thus, the supply of an air fuel mixture to the engine is increased in response to the actuating signal, and the engine idling speed is stabilized.

摘要： An anti-skid brake control system is capable of optimizing vehicular braking characteristics in order to minimize the braking distance. The anti-skid brake control system takes a feature of the vehicle speed dependent wheel slippage threshold. For this, the anti-skid brake control system of the invention employs a wheel slippage threshold deriving means which derives a wheel slippage threshold on the basis of a vehicle speed. The wheel slippage threshold is compared with an actual wheel slippage detected on the basis of a vehicle speed and a wheel speed. Brake pressure in a wheel cylinder is reduced when the detected wheel slippage is increased across the wheel slippage threshold.
