The speed of a vehicle and the distance of the vehicle from at least one other vehicle are autonomously controlled. When the driver is inattentive and at least one other criteria is fulfilled, at least one measure increasing driving safety is introduced.

Method for operating a distance and speed regulating function of a vehicle and driver assistance system for carrying out the method

In a method for regulating the distance between a vehicle and another vehicle traveling ahead, vehicle state variables, vehicle characteristic variables are determined together with the distance from and velocity of at least one other vehicle in the vicinity. The distance from the other vehicle and the vehicle's own velocity are set to permitted limiting values. To increase driving safety, the vehicle's own velocity or the setpoint distance from the other vehicle traveling directly ahead are determined as a function of the vehicle velocity of at least one other vehicle traveling to the side, or of the distance between a plurality of other vehicles traveling to the side.

Method for regulating the distance between a vehicle and another vehicle traveling ahead and a distance-regulating system

A vehicle guidance system for assisting a driving lane change includes an object detection unit for detecting objects in a laterally adjacent rearward side space area of the vehicle. An analysis unit receives signals from the object detection unit and determines whether an object is situated in a dead angle section (blind spot) of the monitored rearward side space, or whether any such object in a section of the monitored rearward side space which is rearward beyond a dead angle section is moving forward at a higher speed than the system vehicle. If so, and if, in addition, it detects at the same time a lane change request pertaining to the corresponding side area, it activates a warning indicating unit for emitting a warning signal. According to the invention, a position detection device is provided which determines path data of the obstacle vehicle and the road geometry data, as well as the position of the system vehicle on the road. When the object detection unit detects an obstacle vehicle which is following in the rearward side space, corresponding to the covered distance recorded by the position detection device and the road geometry, a position assignment of the vehicle which is following is determined relative to the road.

A process for detecting and reporting traffic situation data of a road system via a respective sample vehicle is provided, in which case an automatic position determination is carried out in the respective sample vehicle at definable points in time and, as a function thereof, pertaining traffic situation data are detected and reported. The road system, together with drive duration data concerning the drive duration to be expected for partial routes of the road system, is stored in the sample vehicles. After a respective position determination, the partial route travelled since the preceding position determination and the pertaining actual drive duration are detected, and via the stored drive duration data, the position to be expected for the actual drive duration and/or the drive duration to be expected for the determined position is determined. Then the deviation is determined between the actual position or drive duration and the expected position or drive duration, after which a traffic situation data reporting operation is triggered only if the deviation is larger than a definable threshold value. The process can be used for obtaining traffic situation data for a highway system.
