摘要： A method of controlling a power steering device controls the output from the power steering device in accordance with a vehicle speed and a steering angle. According to this method, the output from the power steering device is caused to be inversely proportional to the steering angle when the vehicle speed exceeds a predetermined vehicle speed and the steering angle is below a given angle and the output from the power steering device is caused to be proportional to the steering angle when the steering angle exceeds the given angle.

摘要： A control device for a power steering apparatus for controlling a torque applied to the power steering apparatus in accordance with a travel condition. A travel condition determining unit generates a travel condition signal in accordance with an average steering angle value and an average velocity value. A load determining unit generates a load signal in accordance with a sensed load condition. A correction signal generating unit generates a correction signal in accordance with the travel condition signal and the load signal. A memory stores a single reference control characteristic for the power steering apparatus. A correcting unit corrects the reference control characteristics in accordance with the correction signal to provide optimal power steering control.

摘要： PURPOSE:To make brake pressure rise more quickly than the brake pressure rise due to a low mu pattern when the second step-on of a brake pedal has been performed after once returning the brake pedal in such a state that anti-skid brake control due to the low mu pattern has started according to the first step-on of the brake pedal, in a brake operation through a double step-on of the brake pedal. CONSTITUTION:When a brake pedal is stepped on during running on a low muroad, brake pressure rises. When a wheel speed drops quickly, pressure reducing control starts. When the wheel speed has recovered, pressure increasing control starts on the basis of the low mu pattern. When the second step-on of the brake pedal has been performed in this state, the pressure increasing control is changed over from the low mu pattern to the high mu pattern. By this changing over, the brake pressure rises stepwise quickly.

摘要： PURPOSE:To eliminate the precipitous feeling which effects during large angle steering operation, by making the output of a steering angle PS device inversely proportional to the steering angle of a vehicle when the vehicle speed exceeds a predetermined value and the steering angle is below a certain angle, and by making the output of the steering angle PS device proportional to the steering angle when the steering angle exceeds the certain angle. CONSTITUTION:When the vehicle speed exceeds a predetermined value such as, for example, 30km/hr, data taken on registers, 4, 5 have less values as the steering angle increases up to a steering angle theta1. At this time a polarity reversing unit 8 delivers an input data thereof as it is since the output of a subtractor 6 is in the direction in which the steering angle increases, and is therefore positive. Accordingly, a subtracter 9 subtracts the result of computation by the subtracter 6 from a value read out from a ROM 3 one clock pulse before. Further, a multiplier 10 converts the value into a solenoid current, and therefore, the output of the PS device is inversely proportional to the steering angle until the steering angle increases to the value of theta1 when the vehicle speed exceeds 30km/hr.

摘要： PURPOSE:To prevent the both splines from being damaged, by temporarily reducing the shaft force after the completion of synchronization of a shift sleeve and quietly attaching the splines each other. CONSTITUTION:When a shift sleeve 30 is synchronized, the relation P1=P2 is established, and the timer in a controller 36 starts,and a solenoid valve 15 is controlled to OFF-state for (t) sec only. Therefore, the compressed air in a pressure chamber is discharged outside, and the shift force of a piston rod is sharply reduced. Therefore, a sleeve spline and a gear spline quietly are brought into contact with each other during the time when the shift force is weak end, and the both splines can be prevented from being damaged.

摘要： PURPOSE:To obtain a power steering equipment with a stable steering force by using the load data detected while parking or running at an extremely low speed as the load data during the travel. CONSTITUTION:The load level at the time when a state is judged that the car speed is not generated for a predetermined time or longer and the load is not changed for a predetermined time or longer is stored in memory, and this value is used during the travel to control a power steering device. The steering force is prevented from being changed by apparent load changes due to the ruggedness of the road surface, and also no time delay is generated to follow the steering force. A load sensor is constituted with link mechanism 103, 104, a clyinder 106, photo-interrupters 3a, 3b, etc.

摘要： PURPOSE:To make it possible to a constant steering force even on uneven road surfaces, by detecting an averaged load in every predetermined period so that the flow rate of oil in a power steering unit is controlled in accordance with the detected averaged load. CONSTITUTION:Since the level of a vehicle body lowers upon heavy load, a shaft 105 moves downward. Meanwhile no substantial change is appreciated in the position of an axle 101 so that a lever 104 rotates about its connecting point with respect to a link 103, and therefore, the shaft 105 rotates in the direction of the arrow. Accordingly, a cylinder 106 also rotates in the same direction as that of the shaft 105 so that a photo-interrupter 61 is aligned with a notch in the cylinder 106, and therefore, light emitted from the light emitting section of the photo-interrupter 61 becomes unshielded by the peripheral edge of the cylinder 106, and is received by the light receiving section of the photo-interrupter 61 which is therefore energized. Upon running of low load a photo-interrupter 62 is energized, and upon running of intermediate load it is deenergized.
