Abstract: An anti-skid brake control system comprises anti-skid brakes fitted to respective drive wheels of an automotive vehicle. When the anti-skid brakes are operated and the rotation of the driven wheels subsequently starts restoration, the inertia moment of a power train drivingly coupled with such driven wheels tending to hamper the restoration is reduced. In other words, until the rotation of the drive wheels is restored, the inertia moment of the power train acts to avoid any possible abrupt drop of the wheel speed of at least one of the driven wheels tending to be locked.

Abstract: When a slip value of the driven wheel on a road surface reaches a predetermined value, the slip control is implemented to apply a braking force to the driven wheel as well as to decrease torque to be generated by the engine. When the brake is operated manually, or when a foot brake is stepped down, only the slip control by application of the braking force to the driven wheel is inhibited.

Abstract: A slip control mechanism of a car has a hydraulic booster for driving a master cylinder for providing hydraulic pressure to a first brake provided for each driven wheel, a second brake provided for each driving wheel, a slip detection device for detecting the slip of driving wheels, a slip control device for operating the second brake, based on signals from the slip detecting device, by using the operating oil of the hydraulic booster as operating oil of the second brake so as to reduce the slip of the driving wheels, the control device comprising a pressure control valve for controlling hydraulic pressure of the operating oil of the second brake, including a pressure reducing valve for reducing the hydraulic pressure of the operating oil of the second brake, detection device for detecting completion of the slip control by the operation of the second brake, and a release device for opening the pressure reducing valve for a predetermined time so as to release the operating oil of the second brake on the occasi

Abstract: A vehicle includes: a power unit, at least a pair of driving wheels rotated by an output from the power unit, fluid pressure cylinders, inserted between a vehicle body and the driving wheels, for adjusting a vehicle height of the vehicle body at a side where the driving wheels are arranged, a fluid pressure source for supplying a high-pressure working fluid to the fluid pressure cylinders, a flow control mechanism for controlling supply and discharge of the high-pressure working fluid to and from the fluid pressure source, a slip detection device for detecting a driving force slip of the driving wheels, a brake device for decreasing a rotating force of the driving wheels, a slip suppressing device for, when the slip detection device detects a slip of the driving wheels, operating the brake device to suppress the slip, and a suspension control device for controlling the flow control mechanism to increase the vehicle height of the vehicle body of the side where the driving wheels are arranged while the slip sup

Abstract: Slip control is carried out so as to reduce torque applied to the driven wheels by reducing torque generated by the engine when a slip value against the driven wheels on pavement is larger than a predetermined value. A shift characteristic of the automatic transmission interposed between the engine and the driven wheels is set as a first shift characteristic which is a basic characteristic at the time of ordinary running where no slip control is carried out and as a second shift characteristic set so as to become at least unlikely to cause downshifting during slip control compared with said first shift characteristic. As the slip control terminates, a return of the first shift characteristic is prohibited when the torque generated by the engine is large (for example, when a degree of operation of an accelerator is not zero) or when downshifting is caused if based on the first shift characteristics.

Abstract: When the driven wheel of the vehicle slips against the road surface to a large extent, such a large slip of the driven wheel can be converged by reducing torque to be applied to the driven wheel by slip control, i.e., by control the throttle valve for adjusting a load of the engine in a direction of forcibly closing the throttle valve prior to operation of the accelerator. In a region of the opening angle of the accelerator nearby its full open region, for example, accounting for 75% or more, a control-unreactive region is provided which is unreactive to slip control, thereby preventing the throttle valve from lowering a given opening angle, for example, 25%. This arrangement can retain the opening angle of the accelerator nearby its full open position even if slip control cannot work normally, thereby ensuring an open state of the throttle valve and allowing the vehicle to run at least to a tune-up factory nearby.
