摘要： An electromagnetic valve has a plunger as an armature of an electromagnetic actuator and a ball as a movable valve member. The plunger and the ball are separated to permit the ball to move freely in response to a pressure difference between an inlet and an outlet when the coil attracts the plunger. If the plunger undesirably moves by a pressure difference between both ends of the plunger, the ball can keep a closing condition during a suction pressure that is higher than a pressure in the inlet. Therefore, an undesired communication between a master reservoir and a pump is avoided.

摘要： A brake squeal control device is proposed which carries out squeal control by specifying travel state and temperature conditions in which brake noise tends to be produced. The brake squeal control device is adapted to feed detection signals from a sensor group that indicates the travel state of the vehicle from a stepping force sensor or wheel speed sensors, and a sensor group that indicates the temperature state from an engine cooling water temperature sensor, a car compartment temperature sensor, a caliper temperature sensor or an outer air temperature sensor to a control circuit. If conditions corresponding to an “in-the-cold” and “first-in-the-morning” states are detected by computing in the control circuit, a solenoid valve is turned on and off to suppress brake squeals.

摘要： A vehicle emergency brake system has a second brake for braking a vehicle by increasing the frictional resistance with the road surface, a millimeter wave radar for detecting any obstacle in an advancing direction, a pedal speed sensor for detecting the step-in speed of a brake pedal for actuating a first brake, and a controller for actuating the second brake. If hard braking by the first brake is detected by the pedal speed sensor, the controller determines whether the vehicle is going to crash into an obstacle detected by the radar. If a determination is made that it will collide, the second brake is actuated. Thus, it is possible to reliably actuate the second brake in an emergency.

摘要： An actuator installed in a vehicle controls brake fluid pressures applied respectively to a first wheel cylinder for a front wheel and a second wheel cylinder for a rear wheel. The actuator includes a first pump for the front wheel, a second pump for the rear wheel, and a motor for driving the first pump and the second pump. The first pump sucks brake fluid and discharges the brake fluid to the first wheel cylinder. The second pump sucks brake fluid and discharges the brake fluid to the second wheel cylinder. In addition, a discharge volume of the first pump is larger than a discharge volume of the second pump.

摘要： An emergency determination mechanism determines whether the necessity of an emergency stop of a vehicle is high. If the emergency determination mechanism determines that the necessity of the emergency stop is high, a granular object sprinkling device sprinkles granular objects on a road surface in front of a vehicle in a running direction. At the same time, when the granular object sprinkling device is operated to sprinkle the granular objects, an ABS control device changes the setting of a target slip ratio as a target value in ABS control from a relatively small first value to a relatively large second value.

摘要： A leaf spring for urging a spool toward a flange part of a yoke is provided between a guide fixed to a housing and the spool. Owing to the urging force of the leaf spring, the spool is pressed against the flange part of the yoke, and the yoke can be pressed against the cover through the spool. Thus it is possible to prevent the spool and the yoke from loosening. Further because the leaf spring is provided for each magnet valve, the leaf spring can be commonly used for respective modes of a fluid control apparatus and thus the cost can be reduced.
