摘要： A brake system includes a reservoir and a master cylinder operable to provide a brake signal responsive to actuation of a brake pedal connected thereto. A power transmission unit is configured for selectively providing pressurized hydraulic fluid for actuating at least one of the pair of front wheel brakes and the pair of rear wheel brakes in a normal non-failure braking mode. A plurality of iso/dump valve arrangements are each hydraulically interposed between the power transmission unit and a corresponding one of the wheel brakes. A plurality of two-position three-way valves are each hydraulically connected with the master cylinder, the power transmission unit, and at least a selected wheel brake of the pair of front wheel brakes. The three-way valves selectively control hydraulic fluid flow from a chosen one of the master cylinder and the power transmission unit to the corresponding one of the front wheel brakes.

摘要： An operation quantity detector detects an operation quantity. Hydraulic passage systems provide connection between hydraulic chambers of a tandem type master cylinder and wheel cylinders. A hydraulic pressure source in the hydraulic passages can pressurize the hydraulic passages based on the operation quantity. Cutoff valves each is installed in each of the hydraulic passages, between the master cylinder and the hydraulic pressure source. The hydraulic pressure detectors detect hydraulic pressures of the hydraulic passages. In the opening command state, a first mutual diagnosis based on the hydraulic pressures and the operation quantity and a second mutual diagnosis based on the hydraulic pressures are performed. In the closing command state, the first and second mutual diagnoses are performed. A failure is detected in the cutoff valves and the hydraulic pressure detecting units based on results of the first and second mutual diagnoses in the opening closing command states.

摘要： A failure check apparatus for a control apparatus of a vehicle such as ABS. When the failure check apparatus performs initial check for the ABS, it successively activates each of solenoid valves and a motor provided in the ABS, one at a time, for a predetermined time so as to determine whether a failure has occurred in the ABS. At that time, activation of the motor is started when a certain delay time elapses after the end of activation of the last solenoid valve. The delay time is a time which the vibration generated in the control apparatus upon activation of the last solenoid valve converges. Thus, interference between a vibration wave (sound wave) generated upon actuation of the solenoid valves and a vibration wave (sound wave) generated upon actuation of the motor, which differ in nature of vibration, is prevented.

摘要： In a method of monitoring an output module to which a number of inductive loads are connected and in which the current flowing through these inductive loads is regulated by clocked driving of the output stages, the current created in the blocked phases of the output stages by the inductively stored energy is partially or temporarily conducted across a common current measuring device and evaluated for testing the output stages, including the inductive loads.

摘要： A device monitors an automatic braking process by using a fault-detecting, operational testing method which takes place via an automatic braking process lasting only briefly, typically about 50 ms. The method is initiated by a test control device and can take place during different vehicle states. If, for example, current through a solenoid valve does not lie within specific acceptable limit values or pedal travel which results from the actuation is not determined at the brake pedal, the device concludes that an operational fault has occurred

摘要： A vehicle brake system of the previously known type has a rear wheel brake booster, between a brake pressure source and an anti-skid apparatus associated with the rear wheels of the vehicle; the brake booster can be switched on by an electrically controllable switchover device. However, switching on of the rear wheel brake booster is effected at the onset of braking only if the anti-skid apparatus is in an operative functional condition. The complex structure of the switchover device in the form of a 3/2-way magnetic valve is a disadvantage. For simplification and economy, the switchover device is provided with an electrically controllable 2/2-way valve and a 2/2-way valve that is mechanically controllable by the stepped piston of the rear wheel brake booster and is built into this brake booster. An electrically controllable 2/2-way valve, which is a component of the anti-skid apparatus, is likewise triggered to activate the rear wheel brake booster.
