摘要： PURPOSE:To secure the stability of a vehicle while improving the turning ability by providing a steering condition detecting means for detecting the steering condition, a running condition detecting means for detecting a vehicle speed or a lateral acceleration added to the vehicle, and a wheel controlling means. CONSTITUTION:A wheel control means steers rear wheels in the inverse phase through a rear wheel steering means when a detected value by a running condition detecting means is less than a predetermined value in response to signals from a steering condition detecting means and the running condition detecting means for detecting the steering condition, and the vehicle speed or lateral acceleration respectively at the time of turning. When the detected value is more than a predetermined value, wheel braking forces are set different between the inner side and outer side in the turning direction to produce a yaw moment for assisting this turn corresponding to the turning condition for the inner and outer wheels in the turning direction. The improvement of turning ability can thus be realized by reduction of an understeer tendency by inverse phase steering of rear wheels in a range where the vehicle speed or lateral acceleration is less than predetermined value, while if it is more than predetermined, it can be achieved by utilizing the differential braking force for braking the wheels. The stability is also secured.

摘要： PURPOSE:To increase the yaw rate generated on a vehicle and improve the turning round and turning performance of the vehicle by increasing the braking force of the inside wheel in the steering direction than that of the outside wheel in response to the sideslip angle of a steering wheel when a driver performs steering. CONSTITUTION:When a steering handle is steered, the braking force of the inside wheel in the steering direction of at least one of front wheels and rear wheels is increased than that of the outside wheel in response to running conditions. The sideslip angle of a steering wheel is detected by a means A. The steering direction of the steering wheel is judged by a means B. The braking force is calculated so that the braking force of the inside wheel in the steering direction of at least one of front wheels and rear wheels is increased than that of the outside wheel based on the sideslip angle of the steering wheel, and a braking force control signal is outputted by a means C based on the calculated braking force. The braking force of the wheel is changed by a means D in response to the outputted braking force control signal.

摘要： PURPOSE:To enhance the cornering performance of a car by furnishing a brake liquid pressure control means to make adjustment so that the brake liquid pressure supplied to either of the left and right wheels becomes smaller than the brake liquid pressure supplied to the other wheel in compliance with increasing stamp force on a brake pedal when the car is put under control. CONSTITUTION:When a car is in cornering brakes, a changeover means 20 is operated to select one of the left and right wheels, and thereupon adjustment is made by control means 13, 14 so that the brake liquid pressure supplied to the outer wheel viewed in the turning direction will become smaller than the brake liquid pressure supplied to the inner wheel. Accordingly a yaw-rate peculiar to the car body is generated on the basis of the synergism of a yaw- moment, which originates from unbalance of brake liquid pressures supplied supplied to the left and right wheels under covering, and a sideways force resulting from operation of the steering wheel. The understeer tendency of the car is offset with this yaw-rate. The steering characteristic of car is transferred temporarily to the oversteer tendency.

摘要： PURPOSE:To make it possible to obtain an inexpensive traction control device by adding an on-off valve and a check valve to an antiskid control device so that a pump and a 3-positional valve of the antiskid control device can also be used respectively as a pressure source and a pressure control valve of the traction control device. CONSTITUTION:When slip occurs at a driven wheel and traction control is necessary, an on-off valve 30 is closed to shut off a passage between a hydraulic brake line portion on a master cylinder side and the master cylinder 6. When a pump 17 on an exhaust pressure line is then driven, the pump 17 sucks and delivers brake fluid from a reservoir tank 33a of the master cylinder 6 via a check valve 33 and pressure-feeds the brake fluid to a 3-positional valve 10a. The 3-positional valve 10a directs the pressure-fed brake fluid controlled to a specified pressure from the pump to driven wheels, while the 3-positional valve is positionally controlled between a pressure increasing position, a pressure retention position, and a pressure decreasing position, to perform the traction control to a minimum extent necessary for eliminating the driving slip of the wheels.

摘要： PURPOSE:To ensure ride-in comfortableness in the time of low speed and stable running in the time of high speed by changing an amplification degree of an amplifier, which amplifies a vertical speed detection value of a car body, in accordance with a car speed detection value, in the case of a control device which outputs an instruction value to a pressure control valve of a hydraulic cylinder. CONSTITUTION:Each control part 34FL-34RR is equipped with an amplification degree- variable type amplifier 35 amplifying each vertical acceleration detection signal from each detector 30FL-30RR by a gain Km, integrator 36 integrating each vertical acceleration detection signal to calculate a vertical speed value, amplification degree-variable type amplifier 37 amplifying this integrated value by a gain Kn, adder 38 adding each output signal from both the amplifiers 35, 37 and a comparator 39 outputting to each pressure control valve 17 an instruction value in accordance with a deviation between a reference value corresponding to a target car height value and an output signal from the amplifier 38. Here the gain Kn of the one amplifier 37 is changed in accordance with a car speed detection signal from a detector 31. For instance, the gain is set so as to proportionally increase in accordance with an increase of a car speed value.
