Abstract: In an automatic braking procedure which can be terminated whenever the brake pedal is moved in the direction of its rest position, a braking pressure which is higher than would correspond to the pedal position of the brake pedal is generated where it is established by a triggering criterion that an emergency braking is in force. The invention ensures that an automatic braking procedure can always be aborted by the driver by the fact that, on the belt lock of the safety belt for the driver, a switching element is actuated when the locking tongue of the safety belt is engaged in the belt lock. It is thereby established whether the driver is belted-up. If the driver is not belted-up, then the execution of the automatic braking procedure is suppressed. An automatic braking procedure can only take place if the driver is belted-up. If high deceleration forces occur, then the driver is held by the safety belt and does not have to brace himself or herself.

Abstract: The invention relates to a method for defining the initiation sensitivity of an automatic braking procedure, in which method the threshold value for the initiation of an automatic braking procedure is reduced as a function of the pedal distance which has been traversed. The object of the invention is to ensure that in the event of actuation of the brake shortly after the automatic braking procedure has terminated, the automatic braking procedure is again initiated rapidly and easily. For this purpose, the initiation threshold value for the automatic braking procedure is reduced within a time period after the satisfaction of the interruption criterion.

Abstract: The invention relates to a method for carrying out an automatic braking process for motor vehicles with an anti-lock brake system. An automatic braking process is triggered when it is detected by the anti-lock brake system that at least one wheel of an axle of the vehicle reaches the locking limit. The brake pressure for the axle of this wheel starts to be controlled by the anti-lock brake system. However, a further increase in brake pressure at the wheels of the other axles of the vehicle is possible since, because of the load distribution of the vehicle and because of the distribution of braking force, the locking limit of the said wheels is not yet reached. According to the invention, a further increase in the brake pressure at the other axles takes place during the automatic braking process.

Abstract: 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.

Abstract: A method for terminating an automatic braking process improves an automatic braking process by assuring that reliable termination of the braking process always takes place. Breaking-off criteria, which are independent of the actuation force of the brake pedal, are provided for the automatic braking process. The variables relating to the dynamics of vehicle movement or the activation time of the automatic braking process, if appropriate also as a function of variables relating to dynamics of vehicle movement, are used as the breaking-off criteria. Thus, automatic braking process is terminated as a function of vehicle behavior. In addition, the gradient of the braking pressure is determined as a function of the activation time and/or as a function of the switch-off criteria when the automatic braking process is terminated.

Abstract: A method for correcting the rotational speeds of vehicle wheels determined by wheel sensors, a measurement of wheel speeds of the wheels of a vehicle being carried out, with specific driving conditions being that the vehicle is being neither accelerated nor braked and has no transverse acceleration. In a first part of the method, a matching of the measured wheel speeds is carried out under the specific driving conditions when the condition that the vehicle speed is below a first threshold value is satisfied. The matching of the measured wheel speeds is carried out by determining a matching factor for each of the two vehicle sides, so that, for example for the left vehicle side, matched wheel speeds are obtained from the measured wheel speeds.

Abstract: A steering control system executes an automatic intervention in the steering of the rear axle when a .mu.-split condition is detected, in order to stabilize the tracking of the vehicle. The steering always takes place in the direction of the vehicle side on which the higher braking torque is generated; this applies also to cornering, irrespective of whether the lower .mu.-value is on the inside of the bend or on the outside of the bend and, furthermore, irrespective of whether the vehicle is being braked or accelerated.
