Abstract: PROBLEM TO BE SOLVED: To ensure desirable braking force reliably without needless energy loss even when the braking force generation efficiency of braking force generating mechanisms lowers. SOLUTION: The braking-based temperature increases Δθinf and Δθinr of the brake rotors of a left front wheel and left rear wheel are computed in S120, S130. The heat-radiation-based temperature decreases Δθdef and Δθder of the brake rotors of both wheels are computed in S140, S150. The temperatures Trf and Trr of the brake rotors of both wheels are computed in S160. From the temperatures Trf and Trr, the coefficients of friction μf and μr between the brake pads and brake rotors of both wheels are calculated in S170. The smaller one of the two coefficients of friction μf and μr is set as a coefficient of friction μ for control in S180. A standard value Pal0 for the lower limit Pal of the accumulator pressure and a standard value Pah0 for the upper limit Pah thereof are corrected with the value μ0/μ in S190, S200.

Abstract: PROBLEM TO BE SOLVED: To satisfy the braking demand of a driver positively even if the demand is generated at the time of parking and stopping on a slope or the like. SOLUTION: This electronically-controlled brake device for vehicle, which is provided with a braking device and an electronic controller for controlling the braking device electrically according to the operation of a brake pedal by a driver, judges a braking demand by a driver based on the stroke of the brake pedal detected by a stroke sensor (S40, 90), judged the parking and stopping conditions of the vehicle based on the condition of an ignition switch (S30, 70, 80), and judged whether or not such a condition as the vehicle is in a parking or stopping condition without a braking demand by a driver has continued for a prescribed time (S60, 110). After such a condition as the vehicle is in the parking or stopping condition without a braking demand by the driver has continued for the prescribed time, the operations of the electronically- controlled brake device and the respective sensors are released (S120, 130).

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.
