    摘要: When a brake switch is switched from OFF to ON, current is applied to a brake ECU, and a command to switch a master cylinder from a second state to a first state is issued after a lapse of preparation time, so that switching-time change suppression control is performed. A reservoir shutoff valve is closed, and duty control is performed on a communication control valve. The duty ratio is set to 1 when a switching-time control duration expires, and the communication control valve is placed in an open position, to establish the first state. Thus, since the communication control valve is duty-controlled during switching from the second state to the first state, change in the hydraulic pressure of an input chamber is suppressed, and change of the operating feeling is suppressed.

    摘要: In a hydraulic brake system including a cylinder device that includes a front chamber and a rear chamber located on front and rear sides of a pressurizing piston, respectively, presence or absence of liquid leakage from a brake line is detected based on a hydraulic pressure in the rear chamber. Where a state in which a subtraction value obtained by subtracting an actual rear hydraulic pressure from a target rear hydraulic pressure is larger than a first malfunction determination threshold value has continued for a time not shorter than a first malfunction determination time, and then an increase of the actual rear hydraulic pressure at a rate not lower than a set rate has caused the subtraction value to become smaller than a return determination threshold value, it is determined that the pressurizing piston has been bottomed due to liquid leakage from the front chamber.

    摘要: A device for controlling the slip between driving wheels and a road surface during a start and an acceleration of a vehicle is maintained at a level which ensures a good acceleration and straight line running stability. The device determines a target speed of the rotation of the driving wheels, and controls a drive torque of the driving wheels in such a manner that the actual speed of the rotation of the driving wheels coincides with the target speed. Also, the device detects a friction coefficient between the driving wheels and the road surface, and the slippage of the driving wheels is controlled on the basis of the friction coefficient. Further, the device determines the reliability of the detected friction coefficient, and uses the detected friction coefficient only when the detected friction coefficient is determined to be reliable.

    摘要: An on-board camera is disposed, behind a neighboring member that is located above a steering column, on the steering column that can move forward at the time of a collision of a vehicle in which the on-board camera is installed. The on-board camera includes: a camera portion; and a support mechanism. The support mechanism supports the camera portion in such a manner that the camera portion can move in a direction away from the neighboring member when the neighboring member and the camera portion are brought into contact with each other because of a forward movement of the steering column at the time of the collision.
