摘要:
In a brake-by-wire vehicle brake system using a feedback control unit (12a, 12b, 31, 36, 45) for producing a brake fluid pressure according to a brake input, a response restricting unit (26, 39, 48) restricts a response property of the feedback control unit when an extraneous brake fluid control operation is detected. Thereby, the control unit is prevented from excessively reacting to changes in the brake fluid pressure caused by the extraneous brake fluid control operation, and the vehicle brake system can provide a highly responsive property and a resistance to changes in the brake fluid pressure at the same time.

Upon occurrence of a change in the load versus fluid loss property, the braking force for the given brake pedal operation amount is changed so that the vehicle operator is enabled to perceive the change in the load versus fluid loss property. In a vehicle brake system comprising a motor actuated cylinder, wheel cylinders, a stroke sensor for detecting a brake pedal operation amount, a target value setting circuit for setting a target stoke of the motor actuated cylinder, and a fluid pressure compensating circuit for correcting the target stoke upon detection of a deviation between a brake fluid pressure reference value corresponding to the brake pedal operation amount and an actual brake fluid pressure in a direction to reduce the deviation, a stroke limiting circuit restricts a compensation value produced by the fluid pressure compensation circuit according to the brake pedal operation amount.

A vehicle brake mechanism includes a master cylinder operated with a brake pedal. A first fluid channel connects a first hydraulic chamber of the master cylinder to a first-circuit wheel cylinder. A second fluid channel connects a second hydraulic chamber of the master cylinder to a second-circuit wheel cylinder. A master cut valve is provided in the first fluid channel and is capable of hindering communication between the first hydraulic chamber and the first-circuit wheel cylinder. A slave cylinder is connected to the second fluid channel and is driven by an actuator to generate a hydraulic pressure. A third fluid channel is provided downstream of the master cut valve and the slave cylinder and connects the first fluid channel and the second fluid channel to each other. A connection control valve is provided in the third fluid channel to close the third fluid channel.

A photo-sensitive resin composition is provided which contains (1) a particulate polymer of a carboxy-group-containing-diene having a cross-linked structure; (2) a polymer having two or more photo-polymerizable unsaturated groups at its molecular chain terminals, and, optionally, a photo-polymerizable unsaturated group, carboxyl group, hydroxy group, amino group, or epoxy group in side chains, or (2') a non-diene-type polymer having a photo-polymerizable unsaturated group, carboxyl group, hydroxy group, amino group, or epoxy group in side chains, or a low molecular weight linear diene-type polymer; (3) a photo-polymerizable unsaturated monomer; (4) a polymer containing an amino group; and (5) a photo-polymerization initiator. The photo-sensitive resin composition has excellent water-developing capability and shows almost no swelling in water, causing minimal reduction in strength and only minimal dimensional changes during development. Resin plates prepared from the composition possess excellent strength after exposure to light, excellent elongation at break, impact resilience and superb transparency, providing a good characteristic balance of properties.
摘要:
A brake fluid pressure electrically generated by a slave cylinder (23) in accordance with an operation amount by a brake pedal (12) is supplied via a VSA system (24) to wheel cylinders (16, 17; 20, 21) provided respectively for wheels. This enables smooth braking by the wheel cylinders (16, 17; 20, 21) by using a brake fluid pressure pressurized by the slave cylinder (23) and including little pulsation. When the VSA system (24) is to individually control the brake fluid pressures supplied respectively to the wheel cylinders (16, 17; 20, 21) to control vehicle behavior, the slave cylinder (23) generates a brake fluid pressure corresponding to a total of the brake fluid pressures required for the wheel cylinders (16, 17; 20, 21). This configuration allows the slave cylinder (23) to generate a brake fluid pressure in just proportion.
