摘要： A method for determining road surface conditions in a system with at least one vehicle and a data processing device. The vehicle exchanges data with the data processing device wirelessly. The vehicle has at least one sensor for determining measured values describing a road surface friction coefficient, and a computing unit. The data processing device includes a database, containing a road map having a plurality of route sections. The method includes determining measured values for a route section by the sensor, determining a first friction coefficient for the route section by the vehicle's computing unit, sending a data record, containing measured values and/or the first determined friction coefficient and a piece of information identifying the route section, to the data processing device, determining an average friction coefficient for the route section, sending the average friction coefficient determined for the route section to the vehicle, and determining the road surface condition.

摘要： A method and system for promoting a uniform driving style. A longitudinal speed of a motor vehicle and a route section curvature radius lying ahead of the vehicle are determined when the vehicle approaches the route section. An expected lateral acceleration is determined from the curvature radius and longitudinal speed as the route section is driven through. The lateral acceleration is compared with a permanently predefined lateral acceleration limiting value which can be predefined by the driver. In the event the expected lateral acceleration is greater than at least one of the lateral acceleration limiting values, the longitudinal speed is lowered by an optical, acoustic and/or haptic request to the driver and/or by autonomous braking intervention. If the expected lateral acceleration is 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.

摘要： A method and device for driver assistance in the event of aquaplaning on a road surface on which a vehicle is traveling, wherein a check as regards whether aquaplaning is presently occurring is performed on the basis of at least one driving dynamics variable, and, in the event of aquaplaning being identified, an intervention for a change in direction is performed at a rear-wheel brake, wherein the brake pressure is set in a manner dependent on a driver steering demand.

摘要： A device for stabilizing a vehicle after a collision against a lateral carriageway boundary, includes a lane recognition system, with which information relating to the course of the lane is determined or detected. A collision detection unit identifies a collision of the vehicle 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. The device also includes a steering actuator for steering a steering system and a brake actuator for controlling one or more wheel brakes. A target path determination unit determines a target path for the vehicle on the basis of the course of the lane determined or detected before or at the time of the collision. A controller guides the vehicle onto the target path and/or stabilizes the vehicle via a steering intervention and/or individual wheel brake interventions.
