摘要： PURPOSE:To make it possible to carry out the precise control of antiskid, and as well to obtain the interchangeability of antiskid devices, by compensating deviations in the speed of vehicle rear wheels. CONSTITUTION:When a vehicle runs straightforward at a constant speed more than a predetermined speed within predetermined acceleration and deceleration in the condition of no braking, a compensating factor for the speed of rear wheels is calculated in accordance with the speeds of wheels 29, 30 detected by sensors 1 through 3. Further, the detected rear wheel speed is compensated by multiplying the rear wheel speed with a factor which is obtained by integrating and averaging the compensating factors. Thus, the detected rear wheel speed is compensated by the compensating factor which is automatically calculated so that precise speed data are obtained, thereby precise brake control is carried out.

摘要： PURPOSE:To prevent the traveling posture of an automobile from getting worse by varying the damping force of a shock absorber for a set time by the control signal for shift-up or shift-down which the electronic controller of an automatic speed change gear generates. CONSTITUTION:A coil 16 is installed in the upper part of the upper movable part 15 of a shock absorber 14, and a rink-shaped core 18 set at the upper edge of a connecting rod 17 fitted into a piston rod 20 is moved upward through the electric conduction of the above-described coil 16. The lower edge of the connecting rod 17 is connected to a flow-rate control valve 19 accommodated in slidable manner in a piston 21 integrally formed with the piston rod 20. Oil circulation between the upper and the lower oil chambers 22 and 23 are carried-out relatively smoothly by deenergizing the coil 16 in ordinary case and setting the flow-rate control valve 19 at the position shown in the figure, and the weakly damped state is maintained. While, when a speed-change instruction signal is output, the coil 16 is brought into conduction, and the passage 25 is closed for a prescribed time by the flow-rate control valve 19, and a strong damped state is formed.

摘要： PURPOSE:To facilitate three-stage control by bringing both end surfaces of a stopper hole into collision with a roller to stop the rotation of a sector gear, and bringing the roller into collision with a concave portion of the stopper hole to stop the sector gear when an electric current flows through a solenoid in a 3- position rotation control actuator. CONSTITUTION:In an actuator 2 having a sector gear 3 engaged with a pinion 2, when an electric current is applied to a micro-motor to rotate the pinion 2 in direction of an arrow 25, the sector gear 3 is rotated in direction of an arrow 26, so that the sector gear 3 is stopped by a roller 8. When an electric current is applied to a coil of a solenoid portion, the roller 8 collides with a cushion 3g at the central concave portion 3a of a stopper hole to stop the sector gear. In this arrangement, the need of a detecton switch for 3-position rotation control is eliminated to simplify the structure.

On the basis of the result, the neutral position omega CENT of a steering gear is calculated. Then, said circuit 1 judges the degree of rolling phenomenon to generate required damping force intensifying signals to drive circuits 10-13 of shock absorbers 6-9 for controlling shock absorbers 6-9.

In this case, a means (f) for varying the period to permit starting calculation of wheel speed is provided in the control circuit (e). The means (f) for varying the period is adapted so that the period to permit starting calculation of wheel speed is elongated with the increase of calculated wheel speed over a range from the low speed region to the high speed region of calculated wheel speed.
