Abstract: PURPOSE: To properly perform antiskid control without delay even in a low speed area by providing a low speed time antiskid control performing means to perform antiskid control when a condition is judged as a low speed condition and a slip condition where a differential value of wheel acceleration is smaller than a prescribed value. CONSTITUTION: When a condition 13 judged as a low speed condition and a slip condition where a differential value of wheel acceleration is smaller than a prescribed value by an ABS computer 14, low speed time antiskid control is performed by an ABS actuator (an antiskid control means) 16. When a wheel is ready to be locked when antiskid control is actuated, A three-position solenoid valve 18 cuts off the master cylinder 26 side by a control signal from the ABS computer 14, and communicates respective wheel cylinders 28a and 28b and a reservoir 22 with each other, and an oil liquid of the respective wheel cylinders 28a and 28b is sent to the reservoir 22, and pressure reducing control is performed.

Abstract: PURPOSE:To restrain rolling at the time of quick steering by operating target roll rigidity from a vehicle-speed and a steering angle so as to change roll rigidity, and making damping force larger and as well reducing the target roll rigidity to correct when this rate of change is more than a defined rate. CONSTITUTION:A control means M4 operates target roll rigidity from a vehicle- speed and a steering angle detected by a vehicle-speed detecting means M2 and a steering angle detecting means M3 so that roll rigidity is altered to a target value in an adjusting means M1. At this time, the rate of change of the target roll rigidity is calculated by a rate of change calculating means M6. A judging means M7 compares it with the defined rate of change, and when it is more than the defined rate of change, it is judged quick steering so as to give instruction for changing damping force to a changing means M8. The changing means M8 instructs a damping force adjusting means M5 to change the damping force highly. A correcting means M9 reduces the target roll rigidity to correct at the time of outputting this changing instruction simulta neously. With this structure, rolling at the time of quick steering can be restrained.

Abstract: PURPOSE:To always perform a proper control by deciding a detection value of car speed not to accurately reflect the actual value and interrupting a change of a stabilizer into its target torsional amount when each rotary condition of a driving wheel and an idling wheel is different from each other exceeding a predetermined correlation. CONSTITUTION:A means M1 adjusts a torsional amount of a stabilizer in accordance with an instruction from the outside. While a means M2 detects a rotary condition of a driving wheel further a means M3 detects a steering angle of a vehicle. A means M4 outputs a changing instruction to a target torsional amount set being based on a car speed and the steering angle, controlling the means M1. In this device, a means M5 detects a rotary condition of a driven wheel. While a means M6 decides whether or not the driving and idling wheels are in a mutually different no-correlation exceeding the predetermined correlation. When the driving and idling wheels are placed in the no-correlation, the changing instruction, output to the means M1 from the means M4, is interrupted in a means M7.

Abstract: PURPOSE:To prevent steering flatter by controlling the valve opening area of a solenoid valve on the basis of the signal supplied from a control circuit, when the traveling speed of a car is in a steering flatter region, and the steering angle is in a minute range. CONSTITUTION:A control circuit 50 is equipped with an analogue/digital coverter 51 which converts the electric signals outputted from a car speed sensor 40 and a steering angle sensor 41 into the respective digital signals, microcopmputer 52 which supplies electric current into the coil of a solenoid valve 34 on the basis of the electric signals supplied from the converter 51, and D/A converter 53 which supplies the electric current corresponding to the signals supplied from the microcomputer 52 into the solenoid valve 34. The rigidity K of a steering operation system is varied below an allowable value of the flatter level by switching the electric current supplied into the solenoid valve 34 to the mode 1 or mode 2 on the basis of the signals outputted from the control circuit 50.

Abstract: PROBLEM TO BE SOLVED: To continue a braking force control by a brake-by-wire even in a decreasing situation of a power supply voltage for controlling a pressure control device. SOLUTION: This brake control device has solenoid opening/closing valves 50FL to 50RR and 60FL to 60RR for controlling the pressure of a working fluid supplied from high pressure liquid supply sources 36 and 38 to wheel cylinders 22FL to 22RR. The solenoid valves of a left front wheel and a right back wheel are controlled by a first control device 76, the solenoid valves of a right front wheel and a left back wheel are controlled by a second control device 84, and the respective control devices have a first power supply 82 and a second power supply 90 for driving the corresponding solenoid valves or the like. It is determined whether a decrease of the power supply voltage may disturb a normal and continuous braking force control by one control device (S20 to 40, 50 to 80). When the voltage may disturb it, solenoid opening/closing valves 64F and 64R are opened to interconnect right and left wheel cylinders, and the other control device (S120 to 250, 320 to 380) controls pressure in the corresponding wheel cylinder.

Abstract: PURPOSE:To prevent engine stall and obtain a small-sized hydraulic pump for controlling a stabilizer by suspending the adjustment for the torsion quantity of the stabilizer, when the number of revolution of an engine mounted onto a vehicle is below a prescribed value. CONSTITUTION:A means M1 determines the torsion quantity of a stabilizer M0 for jointing the lower member of the right and left springs of a vehicle, based on at least the car speed and steering angle. Further, a means M2 adjusts the stabilizer M0 so that the determined torsion quantity can be obtained. While, a means M3 detects the number of revolution of an engine mounted onto the vehicle. When the detected number of revolution is less than a prescribed value, a means M4 stops the adjustment of the torsion quantity detected by the means M2. Therefore, when the load of the engine increases, engine stall can be prevented even if idle-up is not executed. Therefore, a hydraulic pump for controlling the stabilizer interlocked with other hydraulic pump, and the hydraulic pump can be made small-sized.

Abstract: PURPOSE:To improve the responsiveness of rolling suppression control by determining a rapid steering condition of a vehicle when a change rate of a target roll stiffness in the vehicle exceeds a predetermined value, and changing a damper force of the vehicle to a high value. CONSTITUTION:Means M1 adjusts a roll stiffness of a vehicle according to an external command. Means M2 and M3 detect a vehicle speed and a steering angle, respectively. Means M4 outputs to the means M1 a command for changing the roll stiffness to a target roll stiffness decided according to the vehicle speed and the steering angle. Means M5 adjusts a damper force of the vehicle according to an external command. Means M6 calculates a change rate of the target roll stiffness. Means M7 determines whether or not the vehicle is in a rapid steering condition where the change rate of the target roll stiffness exceeds a predetermined value. If it is determined that the vehicle is in the rapid steering condition, means M8 outputs to the means M5 a command for changing the damper force to a high value.
