摘要： PURPOSE: To enable the easy correction of deviation of a vehicle caused by braking force difference between lateral wheels even in the case of an anti-skid device being actuated when the lateral wheels are on the road surface with different friction coefficients. CONSTITUTION: A power steering electrical control unit 27 receives an anti-skid operating signal AS from an anti-skid electrical control unit 17 and detection signals, indicating braking oil pressure PL, PR to be supplied to wheel cylinders 14a, 14b for lateral front wheels 15a, 15b, from oil pressure sensors 29a, 29b so as to detect that an anti-skid device is in operation and that the braking force difference between the lateral front wheels is large. Upon detection, oil pressure supplied to reaction adjusting mechanism 25 in a control valve 21 is controlled by controlling a solenoid valve 26 so as to reduce steering reaction imparted to the operation of a steering wheel 22 by the reaction adjusting mechanism 25.

摘要： PURPOSE:To obtain a brake device which supplies the hydraulic pressure of a hydraulic pressure source to a wheel cylinder through the control to the hydraulic pressure corresponding to the operation force of a brake operating member, electrically control the hydraulic pressure and provides high reliability. CONSTITUTION:The hydraulic pressure supplied from an accumulator 46 is adjusted to the nearly equal level to the hydraulic pressure of a master cylinder 12 by the first hydraulic pressure control valve 42. The piston which receives the master cylinder hydraulic pressure of the first hydraulic pressure control valve 42 is sealed by a sealing member, and the leak of the brake liquid is prevented. The hydraulic pressure adjusted by the first hydraulic pressure control valve 42 is supplied to the second hydraulic pressure control valve 44, and is used as the pilot hydraulic pressure for controlling the hydraulic pressure of the accumulator 46. Even if the brake liquid supplied from the first hydraulic pressure control valve 42 leaks into the second hydraulic pressure control valve 44, the liquid is supplied from the accumulator 46, no trouble is generated.

摘要： PURPOSE:To provide a driving device which can move a member to be driven even in the case where an ultrasonic motor can not be rotated. CONSTITUTION:An ultrasonic motor 60 is provided in a device main body 64 fixed to a caliper 32. A nut 84 is engaged with a rotor 78 of the ultrasonic motor 60 so that it can not be rotated relatively, and a screw shaft 94 is screwed to the nut 84. The rotation of the screw shaft 94 in relation to the device main body 64 is hindered by fitting a stopper plate 118 in a slit 114 and a notch 116. At the time of operating a parking brake, current is supplied to the ultrasonic motor 60, and a piston 44 pushes an inner pad 14 to a friction surface 12 with an ahead of the screw shaft 94. In the cafe where the current can not be supplied to the ultrasonic motor 60, a cover 112 is removed, and the stopper plate 118 is removed to rotate the screw shaft 94 and make the piston go backward.

摘要： PURPOSE:To improve the controllability of antilock control by constituting the braking force of a control means on one side to be zero at a time when a control means on the other is in the antilock control, in the controller of an electric automobile with two system braking means. CONSTITUTION:An electric automobile 1 runs after driving four wheels 3 to 6 by motors (regenerative braking) 7 to 9, while it has two system braking means, namely, four hydraulic brakes 16 to 19 and these motors (regenerative braking) 7 to 9. An antilock controller is so constituted that only either control means executes antilock control in response to a wheel lock state. In brief, in the hydraulic brakes 16 to 19, by way of example, when antilock control is started by a hydraulic brake electronic control unit, the motors (regenerative braking) 7 to 9 or control means on the other are controlled so as to make the braking force become zero by a motor control electronic control unit. Accordingly, the antilock control by the control means on one side is not affected by the control means on the other, so that controllability is thus improved.

摘要： PURPOSE:To obtain a disc brake which perform braking by driving a motor and has a parking brake mechanism. CONSTITUTION:A spline hole 48 is formed on a cylinder part 38 of a caliper 36 for fitting an ultrasonic motor 50 being incapable of relatively rotating and capable of axially moving. By operating the ultrasonic motor 50 by means of a torque according to an operation amount of a braking pedal, a piston 46 screwed with a screw rod 62 is moved forward, and a disc brake is in an action condition. When a parking brake operation lever is operated, a parking lever and a shaft 122 are rotated. The rotation is converted into axial movement of a push rod 142 and a movable member 140 by means of a cam surface 144. The movable member 140 moves the ultrasonic motor 50 forward accordingly, and the piston 46 is also moved forward in a united form bringing about the action condition of the disc brake.

摘要： PROBLEM TO BE SOLVED: To improve the practical use of a steering system for a vehicle equipped with a steering force transmission device having a mechanism transmitting rotation while changing the rotational phase difference between two shafts.
SOLUTION: In place of or in addition to turning assistance control causing a turning assisting device to generate force as assisting force corresponding to steering force transmitted by the steering force transmission device, operating amount-based control can be executed for causing the turning assisting device to generate force based on the operating amount when the operating amount of a steering operation member is smaller than a predetermined operating amount. By the operating amount-based control, for example, force for actively turning wheels can be generated, and thereby the deterioration of operational feeling caused by the presence of a clearance between an engaging part and a guide passage can be suppressed when operating in the vicinity of the neutral operating position during traveling of the vehicle.

摘要： PROBLEM TO BE SOLVED: To provide a steering device capable of performing a large tilt operation while suppressing the deterioration of a commodity property.
SOLUTION: A universal joint 14 for connecting a second steering shaft 122 with a third steering shaft 123 receives a biasing force so as to set to a prescribed rotating position in a direction around a shaft by a plate spring 15 mounted in the third steering shaft 123. The prescribed rotating position is set to the rotating position where the second steering shaft 122 can rock (a tilt operation) at an angle wider than a prescribed angle with respect to the third steering shaft 123, which allows a large tilt operation. Even when the universal joint 14 receives the biasing force of the plate spring 15 to be rotated, at this time, a steering wheel 11 is prevented from being rotated by bringing the first electromagnetic clutch 13 in a disengagement. Therefor, the steering device can perform the large tilt operation while suppressing the deterioration of a commodity property.

摘要： PROBLEM TO BE SOLVED: To provide a vehicular steering device capable of facilitating the driving of a vehicle by taking into consideration the degree of familiarity of a driver to a steering characteristic of the steering device. SOLUTION: An electronic control unit 36 inputs a detection value from each sensor in a Step S11. In a Step S12, a coefficient Nk_0 of familiarity for indicating the degree of familiarity to the steering characteristic of a driver is determined by using the input detection value. In a Step S16, when the coefficient Nk_0 is close to "0", a small target turning angle δd is calculated, and when the coefficient Nk_0 is close to "1", a large target turning angle δd is calculated. In a Step S17, when the coefficient Nk_0 is close to "1", a time constant τ of a turning actuator 21 is set to be a large value, and when the coefficient Nk_0 is close to "1", a small time constant τ is set. In a Step S18, when the coefficient Nk_0 is close to "0", large reaction force torque Tz is calculated, and when the coefficient Nk_0 is close to "1", small reaction force torque Tz is calculated.
