摘要： A process for calculating estimated vehicle speeds on the basis of wheel speeds of the vehicle wheels and a value resulting from addition of an offset value corresponding to an output error including a dispersion component and a slope component of an output from a longitudinal acceleration/deceleration sensor to a detection value detected by the longitudinal acceleration/deceleration sensor. In a condition in which it is determined that a vehicle is traveling at a substantially constant speed for a relatively long period of time, a first correction amount is calculated from an average value of variations in wheel speeds and an average value of outputs from the longitudinal acceleration/deceleration sensor during the long period of time. In a condition in which it is determined that the vehicle is traveling at a substantially constant speed for a relatively short period of time, a second correction amount is calculated from the average value of variations in wheel speeds and the average values of outputs from the longitudinal acceleration/deceleration sensor during the short period of time. An amount of correction of the zero point of the longitudinal acceleration/deceleration sensor is determined by the first correction amount, and the correction of the offset value is determined by the second correction amount.

摘要： A vehicle brake apparatus in which a self-locked state of a cut-off valve is quickly relieved if the valve becomes stuck in the self-locked state. The vehicle brake apparatus comprises a master cylinder to have wheel cylinders generate a braking force, master cut-off valves of a normally open type, a slave cylinder electrically driven to apply a braking force to the wheel cylinders. The apparatus also includes pressure sensors for detecting brake fluid pressures generated by the master cylinder and the slave cylinder, and out-valves through which the brake fluid pressure on the wheel cylinders is reduced. If the brake fluid pressure corresponding to a depressing stroke of a brake pedal becomes higher than a valve openable pressure on the master cut-off valves while the brake pedal is being operated, the brake fluid pressure on the wheel cylinders is reduced through the out-valves.

摘要： 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.

摘要： Under a normal condition, brake fluid pressure generated by a slave cylinder (23) that operates according to operation of a brake pedal (12) is fed to a wheel cylinder (16, 17; 20, 21) to perform braking, while under a fault condition of the slave cylinder (23), brake fluid pressure generated by a master cylinder (11) for backup that operates by the operation of the brake pedal (12) is fed to the wheel cylinder (16, 17; 20, 21) to perform braking. In the latter case, brake fluid fed by a pump (64) is fed to the wheel cylinder (16, 17; 20, 21), before the brake fluid is fed from the master cylinder (11) to the wheel cylinder (16, 17; 20, 21) by a driver depressing the brake pedal (12). Accordingly, without leading to an increase in the stroke of the brake pedal (12), a required amount of brake fluid can be fed to the wheel cylinder (16, 17; 20, 21) to thus ensure a sufficient braking force.

摘要： Systems and methods to prevent dragging of a fluid pressure type disk brake system are described herein. Brake fluid pressure generated by a master cylinder during a braking operation is transmitted to a wheel cylinder via a VSA system. The VSA system includes a low pressure accumulator and an out-valve disposed between the wheel cylinder and the low pressure accumulator. Temporarily opening the out-valve during a braking operation allows part of the brake fluid that would otherwise be supplied to the wheel cylinder to be supplied to the low pressure accumulator. After the braking operation by the driver is completed, brake fluid supplied to the wheel cylinder is returned to the master cylinder. Thus, a piston of the wheel cylinder is withdrawn by an extra amount corresponding to the amount of brake fluid supplied to the low pressure accumulator, thus reliably prevents disk pad dragging in the disk brake system.

摘要： A brake system includes a master cylinder which generates brake fluid pressure by a braking operation of a driver, an electric motor-driven slave cylinder which generates brake fluid pressure based on an electric signal responsive to a braking operation of a driver, and a wheel cylinder for braking a wheel by the brake fluid generated in the master cylinder or slave cylinder. During normal operation of the brake system, the brake fluid generated in the slave cylinder is transferred to the wheel cylinder. During abnormal operation of the brake system, the brake fluid generated in the master cylinder is transferred to the wheel cylinder. The brake system also includes an opening and closing valve in a fluid passage connecting the slave cylinder to the wheel cylinder. When a problem occurs with the slave cylinder, the opening and closing valve is closed for a predetermined amount of time.
