Abstract: In an automotive vehicle brake system with an arrangement (rear-axle ABS) which controls or regulates the braking pressure or the brake force on the rear wheels and prevents locking of the rear wheels, the front wheels and the rear wheels are individually equipped with rotational speed sensors. Further, the distribution of the brake force to the front and rear axle (EBD function) is controlled or regulated on the basis of the rotational speed sensor signals and by means of the arrangement (rear-axle ABS) which prevents locking of the rear wheels. In addition, there is provision of an indicator and/or alarm device which signals the imminent locking of a front wheel or the second front wheel to the driver.

Abstract: A braking force distribution control device is provided in which wheel speeds of respective wheels of a vehicle are detected. On the basis of the detected wheel speeds, slopes of coefficients of friction &mgr; between the wheels and a road surface are estimated as road surface &mgr; slope values of the respective wheels. On the basis of the estimated road surface &mgr; slope values of the respective wheels, braking forces of the respective wheels are controlled such that the braking forces among the respective wheels are adjusted.

Abstract: A vehicle brake control wherein a driver generated braking prompt signal is compared with a measured deceleration signal and, according to which, a correction signal is generated. The correction signal is processed with the braking prompt signal into an output signal. The correction signal is constantly maintained over one or more clock pulses when the value of the deceleration signal lies within a given value range or tolerance band. However, the correction signal is changed from one plus to the next when the instantaneous deceleration lies outside said tolerance band.

Abstract: An anti-lock brake control method or device which maintains the vehicle stability even if the vehicle drives onto the &mgr; split road surface from a normal road surface. The anti-lock brake control method or device comprises a means to determine the hydraulic pressure in the wheel cylinder of the right and left wheels and a means to change the threshold value which lowers the threshold value for the wheel cylinder of the front wheel with the higher hydraulic pressure to be switched into the pressure reduction mode when the hydraulic pressure difference between the wheel cylinders of the right and left front wheels reaches or exceeds the predetermined hydraulic pressure.

Abstract: A method and device for detecting the lockup of a transport device wheel. The rotating of the wheels is detected using sensors. Data about the rotating of the wheels is relayed to a control unit which monitors the rotating of the wheels for a predetermined control period. If the control unit detects, on the basis of the information received from the sensors, that at least one of the wheels is locked up, the control unit sends an alarm unit a command for raising an alarm. When the alarm unit receives the command, it raises an alarm to warn the driver that one or more wheels are locked up.

Abstract: A controller for an electric brake system in a vehicle. The brake system utilizes switched reluctance electric motors to apply braking force to wheels. Such motors have non-ideal torque-speed characteristics, wherein excessive amounts of time and current are required to change torque delivered. The invention reduces the times, and currents, by adjusting the phase angle, and durations, of current pulses delivered to the coils of the motor. The adjustment is based on several parameters, including presently demanded torque, speed of the electric motor, deviation of vehicle system voltage from a norm, and deviation of motor temperature from a norm.

Abstract: An automotive brake control system with an ABS system employing a hydraulic modulator, wheel-speed sensors, and a skid control unit. A vehicle deceleration &Dgr;Vi is calculated on the basis of a first speed V0 corresponding to the pseudo vehicle speed calculated at a time when the vehicle starts to decelerate and a second speed Vp corresponding to the pseudo vehicle speed calculated at a time when the pseudo vehicle speed is changed from an increasing state to a decreasing state at each cycle of the skid control, from a predetermined expression &Dgr;Vi=(V0−Vp)/T, where T denotes a derivative time.

Abstract: An antiskid brake controller which utilizes measured wheel speed in order to provide brake control for a vehicle such as an aircraft. The measured wheel speed is differentiated to determine the deceleration of the wheel, and the controller then compares the deceleration to a predefined deceleration threshold. If the wheel decelerates faster than the deceleration threshold, the controller reduces the command pressure provided to the brakes by a scaling factor. Full command pressure may eventually be applied otherwise. The controller is capable of operating based only on measured wheel speed.

Abstract: A device for detecting electromagnetic stray effects in systems with at least two inductive sensors which provide an essentially periodic output signal, performs a signal evaluation for evaluating signals of the sensors, a test for detecting an electromagnetic stray effect, whether periods of the signals to be evaluated lie within a period length of expected stray effects, a test, if applicable, whether detected signal progressions have at least a progression typical for stray pick-up, plausibility tests by means of at least one further detected signal in which a signal to be checked is compared with parallel measured other signals, and detecting a stray effect only if all tested conditions provide a result which is typical for stray effects.

Abstract: An improved control system for antilock brake control for an automotive vehicle which includes an excessive brake pedal-depressed force alarm unit. The control system determines a slip ratio and a slip ratio variation of a wheel to derive slippage conditions of the wheel, and provides an alarm to a driver when a brake pedal-depressed force exerted on a brake pedal is too great, causing wheel slippage to occur, especially during traveling on a slippery road surface such as a snowy road.

Abstract: An information lamp flashes when instability is detected, whether the system is switched on, off or limited in its functional scope. When the traction control system is switched off or limited in its functional scope and no instability is detected, the lamp lights up continuously.
