The invention relates to a method for monitoring tyre-pressure monitoring systems in a motor vehicle. Said motor vehicle comprises an indirect measuring tyre-pressure monitoring system, which identifies a tyre-inflation pressure loss based on wheel-speed information and a direct measuring tyre-pressure monitoring system (TPMS), which identifies a tyre-inflation pressure loss using tyre-inflation pressure values that are measured directly on the vehicle tyres by means of pressure modules. According to the invention, a warning that is emitted by a pressure module of the direct measuring tyre-pressure monitoring system (TPMS) relating to a tyre-inflation pressure loss is only transmitted to the vehicle driver, if said tyre-inflation pressure loss is confirmed by the indirect measuring tyre-pressure monitoring system or by all pressure modules that are still operating correctly. The invention also relates to a computer programme product.

Disclosed are a method and an device for assisting drivers in the event of aquaplaning on a road surface on which a vehicle travels; at least one variable relating to vehicle dynamics is used to verify whether an aquaplaning event is occurring, and if if an aquaplaning event is acknowledged, an intervention is performed on a rear wheel brake (42, 46) in order to change directions, the brake pressure being adjusted in accordance with a steering maneuver desired by the driver.

The invention relates to a method for promoting a uniform driving style in which a longitudinal speed of a motor vehicle (11, 21, 302) and a curvature radius of a route section (13) lying ahead of the motor vehicle (11, 21, 302) are determined when the motor vehicle approaches the route section (13), wherein an expected lateral acceleration is determined from the curvature radius and the longitudinal speed as the route section (13) is driven through, and said lateral acceleration is compared with a permanently predefined lateral acceleration limiting value which can be predefined by the driver, and wherein in the event of the expected lateral acceleration being greater than at least one of the lateral acceleration limiting values, the longitudinal speed is lowered by means of an optical and/or acoustic and/or haptic request to the driver and/or by means of an autonomous braking intervention, until the expected lateral acceleration reaches the lower of the two lateral acceleration limiting values. The method is defined by the fact that in the event of the expected lateral acceleration being smaller than or equal to the lower of the two lateral acceleration limiting values the lowering of the longitudinal speed is reduced by decreasing the engine drag torque. The invention also relates to a corresponding system.

The invention relates to a device for stabilising a vehicle, in particular after a collision against a lateral carriageway boundary, comprising a lane recognition system (1), with which information relating to the course of the lane (K act ) is determined or detected, a collision detection unit, which identifies a collision (T crash ) of the vehicle, in particular against the lateral lane carriageway boundary, on the basis of signals from at least one sensor or on the basis of a driving state variable (ay, ax, V veh ), determines an, in particular electrically controllable, steering actuator for steering a steering system, and an, in particular electrically controllable, brake actuator for controlling one or more wheel brakes, a target path determination unit, which determines a target path (K ref ) for the vehicle, on the basis of the course of the lane determined or detected before or at the time of the collision, and a controller (2), which causes a guiding of the vehicle onto the target path and/or a stabilisation of the vehicle via a steering intervention, in particular a control of the steering actuator, and/or using individual wheel brake interventions, in particular a control of the brake actuator, and a method for stabilising the vehicle.

The invention relates to a method for improving the driving stability of a motor vehicle, wherein driver-independent braking interventions are triggered when a critical driving situation is expected on the basis of route information and current position data of the motor vehicle. The invention also relates to a corresponding system. According to the invention, the driver specifies information on the friction coefficient to be maximally used via a human-machine interface, said friction coefficient being used as the basis for the prediction of a critical driving situation.

The application relates to a device and a method for increasing the safety of a motor vehicle. A first sensor unit (2) senses the surroundings, in particular in order to detect free spaces and objects (0), and the position and movement thereof. A second sensor unit (20) senses the state of the surroundings, a third sensor unit (30) senses the state of the vehicle, and a fourth sensor unit (40) senses the driver's commands. The data are merged and a driving safety coordinator (6) determines at least one reliable driving corridor (K1, K2, K3, K4 to Kn) predictively and situationally in order to determine the operational safety. The driver's command can be limited to the driving corridor (K1, K2, K3, K4 to Kn) by means of components (9) which can be actuated actively and/or the motor vehicle (1) can be kept in the driving corridor (K1, K2, K3, K4 to Kn) by means of the components (9) which can be actuated actively.

The invention relates to a method for carrying out an avoidance manoeuvre of a motor vehicle. In a first method step, an object in the surroundings of the motor vehicle, with which the motor vehicle is on a collision course, is detected. A warning is then output to the driver of the vehicle to the effect that the motor vehicle is on a collision course, and the steering activity of the driver of the vehicle is detected. An externally actuable rear-wheel steering device is subsequently switched in such a way that the front wheels and the rear wheels of the motor vehicle are steered in the same direction. Furthermore, the invention relates to a device for carrying out an avoidance manoeuvre. So that the driver of the vehicle continues to be able to control an avoidance manoeuvre with front and rear wheels which are steered in the same direction, the invention provides that the vehicle movement dynamic effects of the externally actuable rear-wheel steering device which is actuated in the same direction are compensated. For this purpose, a further warning is output to the driver of the vehicle in order to prompt the driver of the vehicle to carry out a greater degree of steering activity which is necessary as a result of the externally actuable rear-wheel steering device being actuated in the same direction.
