The invention relates to a method for controlling a motor vehicle, in particular a traction-slip control system (TCS), wherein a diagonal axle twist is detected and evaluated as a regulating variable.

Method for controlling a vehicle

The invention provides a method of detecting a defective condition on a pressure switch arrangement which at least assumes a defective condition on the said pressure switch assembly whenever a signal arrives at an input of an electronic computing unit which cannot be associated either to the opened or to the closed condition of the pressure switch. Moreover, a defective condition on the pressure switch arrangement mounted in the brake system of a vehicle is assumed, once the pressure switch signal refers to an actuated brake although the vehicle is significantly accelerated. Conversely, a defective condition is also assumed if the vehicle significantly decelerates although the pressure switch signal refers to a lack of brake pressure. Also, an appropriate pressure switch arrangement is provided which, with the pressure switch closed, generates a rectangular signal and, with the pressure switch opened, generates a high level on the input II of an electronic computing unit. With an incoming low level, an error on the pressure switch arrangement is assumed.

Method and apparatus for detecting a defective pressure switch

A process of testing individual components of a system in an automotive vehicle, wherein the system comprises at least one software-operated controller and the controller is adapted to be connected to an input station, with software being adapted to be uploaded to the input station from the controller and a test software being uploaded from the input station to the controller prior to a check of the components of the system.

Process for inspecting the components of a system in a motor vehicle

The present invention discloses a method for use in automotive vehicles with an electronically controlled brake system (for example, ABS), wherein for controlling the braking pressure (re)increase during a control operation the rotational behavior of the individual wheels is measured and evaluated to determine braking pressure control signals, and wherein during a braking pressure control operation the braking pressure reduction in the previous cycle (,) is taken into account for the control of the braking pressure reincrease (,). According to the present invention, a braking pressure rise gradient (G) is calculated on the basis of the braking pressure increase in the preceding braking pressure increase phase (,), and the braking pressure increase or the variation of the braking pressure increase is calculated and predetermined on the basis of the rise gradient (G) and the calculated wheel cylinder pressure (P2) at the commencement of the current braking pressure increase phase (,) and on the basis of the current calculated locking pressure level (N3).

Method and brake system for control of brake pressure build-up during a control process

A method of electronic brake force distribution is applied to contribute to vehicle stability even in the event of failure of the system that detects failure of the front-axle brake circuit (,) in a vehicle (,). The method involves initiating a pressure maintenance or pressure reduction phase only after the standards with respect to a minimum vehicle deceleration upon brake circuit failure are met. This way, it is ensured that the standards are observed, on the one hand, and locking of the rear wheels (,) before the front wheels (,) is prevented with great likelihood, on the other hand. Thus, electronic brake force distribution (EBD) is switched over to less sensitive criteria. This makes allowance for both possibilities in the event of a failure of a pressure switch (,), i.e., that the front-axle brake circuit (,) is intact or that it is defective.

A circuit configuration for improving the driving behavior of an automotive vehicle tending to oversteering, which vehicle is equipped with an anti-lock control system, causes the slip and deceleration thresholds, decisive for the onset of control at the front wheel on the outside of the bend, to be raised upon the occurrence of a cornering identification signal.

A circuit configuration for a brake system with anti-lock control and/or traction slip control including circuits (4) for improving the control during cornering. In the presence of a wheel rotational behavior typical of cornering when during a control action the wheel slip, that means the deviation of the wheel speed from the vehicle reference speed, exceeds the slip threshold (SO), this wheel rotational behavior lasting despite reduction of the braking pressure and the deceleration-responsive/acceleration-responsive control thresholds not being attained, the wheel slip is augmented by an offset (.DELTA.SO) for an invariably preset period of time or a period of time which is dependent on the further wheel rotational behavior, on the braking pressure variation and/or other control criteria.
