Abstract: A method and device for identifying and classifying objects, electromagnetic radiation being emitted by a sensor, the radiation components reflected on objects being received by the sensor, the received signals being analyzed by comparison with stored characteristic values and the class of the reflecting object being deduced on the basis of the analysis. To this end, an analyzer is provided for analyzing the received signals, a memory is provided for storing characteristic patterns, its stored patterns being compared with the analyzed signals and thus the class of the reflecting objects being deducible on the basis of the comparison.

Abstract: A method and a device for controlling automatic emergency braking of a motor vehicle to reduce the severity of a collision of a vehicle with an object, the position and/or speed of the object with respect to the host vehicle being determined via an object detection device, and this information being sent to a collision detection device which ascertains whether a collision with an object is imminent and, on detecting a collision, triggers emergency braking and ascertains a collision instant, emergency braking being terminated after the period of time until the determined collision instant has elapsed.

Abstract: Described is a data transmission path including a device for checking the data integrity of data transmitted from the sender side to the receiver side of the data transmission path, in a motor vehicle in particular, having a first data modification device on the sender side and a second data modification device on the receiver side which each have the same transmission function and a comparator for comparing the output data of the data modification devices. Input data are modified into output data on the sender side and transmitted to the receiver side, and identical input data are transmitted to the receiver side and modified there into output data. Moreover, a method for checking the data integrity is described.

Abstract: A method and a device for warning the driver of a motor vehicle. An object detector is provided, which detects preceding vehicles and ascertains their distance and relative velocity with respect to the host vehicle and supplies these to an evaluation device. The evaluation device assumes that the preceding vehicle would perform a deceleration and ascertains as a further function of the variables measured by the object detector and the driver's reaction time and the host vehicle's maximum possible deceleration whether a collision with the preceding vehicle would be avoidable. If an unavoidability of a collision is recognized, then a driver warning device is activated.

Abstract: A method and a device for warning the driver of a motor vehicle about a traffic situation involving an increased collision risk are provided. For this purpose, signals of at least one object detector representing motion quantities of detected objects and signals of at least one motion sensor system of the host vehicle are suppliable to an analyzer device. The computing device precalculates all possible motion trajectories for all detected objects and for the host vehicle, taking into account maximum acceleration or deceleration values and maximum change in acceleration or deceleration values over time and, when an imminent collision is recognized, issues a warning to the driver that higher acceleration or deceleration values and/or change in acceleration or deceleration values are needed to avoid a collision.
