Abstract:
1. An adaptive cruise control for a motor vehicle, comprising: a sensor system for locating preceding vehicles; a controller to regulate at least one of a speed of the motor vehicle and a clearance from a preceding vehicle, based on specified control parameters; a traffic jam detection device, wherein the output of the traffic jam device indicates one of: a) a traffic jam and b) no traffic jam, wherein, the output is calculated from an integrated variable indicating a probability of a traffic jam, wherein a value of the integrated variable is a) decreased, if the speed of the motor vehicle is above an upper limiting speed, and the value of the integrated variable is above a lower threshold, b) held constant, if the speed of the motor vehicle is below a lower limiting speed, c) increased if the speed of the motor vehicle is between the upper limiting speed and the lower limiting speed, and the value of the integrated variable is below an upper threshold; and a specification device to adjust the control parameters for a detected traffic jam situation.
