Abstract:
1. A device for adaptive distance and speed control in a motor vehicle, comprising: a sensor device to measure a distance and a relative speed of a target object located in front of the vehicle; a regulating device having a distance control function to regulate to a specific distance to the target object, the regulating device configured to output temporally changeable actuating variables to actuating elements of at least one of a drive system and a brake system of the vehicle; a torque dampener configured to limit at least one of: i) the actuating variables, ii) the temporal changes of the actuating variables; and a dynamic device configured to detect a sudden change in a traffic situation ascertained by the sensor device and to restrict a function of the torque dampener according to the situation, maintaining distance and speed control; wherein the dynamic device is configured to receive the actuating variables conveyed to the torque dampener and to detect a switch of actuating elements as criterion for the sudden change in the traffic situation based on the actuating variables.
