摘要： Methods for transitioning a braking system between primary and fallback modes are provided. A method in accordance with the present disclosure may include identifying a failure in the functionality of the primary braking system, and, upon identifying the failure, mitigating an abrupt increase in a pedal travel distance required to brake or otherwise decelerate the vehicle so as to provide smooth transition from a primary braking mode to a fallback braking mode. The mitigating the increase in the pedal travel distance may include initiating a transition to the fallback braking mode, activating at least one of a plurality of transition braking modes, and gradually increasing the pedal travel distance by deactivating at least one of the previously activated transition braking modes.

摘要： A vehicle motion control device which detects an abnormality of an automatic hydraulic pressure generator having a master cylinder, a booster which boosts the master cylinder and a booster actuator which actuates the booster irrespective of brake pedal operation and performs an appropriate transaction upon detecting the abnormality. The vehicle motion control device includes the automatic hydraulic pressure generator, a hydraulic pressure control valve disposed between the automatic hydraulic pressure generator and a wheel cylinder, and a controller performing the automatic pressure increase control by actuating the hydraulic pressure control valve and the booster actuator according to the vehicle running condition. By calculating a master cylinder hydraulic pressure based on a variable state of the booster actuator and comparing the calculated value with the master cylinder hydraulic pressure detected by a hydraulic pressure sensor, an abnormality of the automatic hydraulic pressure generator is detected during non-operation of the brake pedal.

摘要： A method and apparatus control target deceleration of a vehicle in response to a master cylinder pressure and the like. A controlled braking mode in which the pressure in each wheel cylinder is controlled based on the target deceleration, and a driver braking mode in which the pressure in each wheel cylinder is directly controlled by a master cylinder. When an abnormality in the braking control is detected, the ratio of the wheel braking force to the amount of driver's braking operation is gradually adjusted closer to the ratio set for the driver braking mode.

摘要： A circuit arrangement for a safety-critical control system, such as ABS, TCS, ASMS, brake-by-wire, etc., has a dual-circuit or multiple-circuit design, and each circuit includes a complete microprocessor system that processes the input data redundantly and delivers an error identification signal (FAIL) when an error or a discrepancy between the redundantly produced data processing results occurs. Upon error detection, there is a transition to an emergency operation mode where either a circuit is disconnected or the actuator activation of both circuits is assumed by the intact microprocessor system. Each of the two systems is equipped with peripherals of its own, comprised of signal detection, actuator activation, and energy supply.

摘要： An anti-lock braking system for a two-axle all-wheel drive vehicle having two intra-axle differentials and an engageable central inter-axle differential comprises a wheel sensor associated with each of the wheels for determining the rotational behavior of each of the wheels, and a four-channel electronic control circuit for providing individual wheel regulation. The electronic control circuit also detects whether the central differential is engaged or not and whether a malfunction has occurred in one of the channels. If one of the regulating channels has a malfunction and the central differential is not engaged, the electronic control circuit switches off regulation only in the malfunctioning channel. If, however, the central differential is engaged when a malfunction in one of the regulating channels has occurred, then the electronic control circuit switches off both the malfunctioning channel as well as an intact channel associated with a diagonally opposite wheel.
