Problems solved by technology

Since with increasing speed the danger of a wrong reaction becomes greater and the consequences of such a wrong reaction become more serious, the underspeed function is only useful below a defined limit speed

Embodiment Construction

[0014] figure 1 Shown is an ACC control module 10, which forms the core component for speed and distance control in a motor vehicle, the functions of which are performed, for example, by one or more suitable programmable microprocessors. Via the input device 12 arranged on the dashboard or steering wheel of the vehicle, the driver can input various commands in order to activate or deactivate various functions of the ACC control module 10 and in particular to input the desired speed in freewheeling. The controller 14 compares the desired speed with the actual vehicle speed V measured by a speed sensor (not shown) and intervenes via the output unit 16 in the drive system 18 and, if necessary, also in the braking system 20 of the vehicle in order to Adjust the speed to the desired speed.

[0015] A localization system 22 , for example in the form of an angle-resolving radar sensor, determines the position of stationary and moving objects in the vehicle's front area and reports t...

Abstract

Device for controlling speed and distance in a motor vehicle, with a positioning system (22) for determining the orientation of an object in the area in front of the vehicle, and a controller for selecting an object whose orientation is determined as a target object for controlling the distance (14) and selection means (24) with a low-speed travel function useful only below the limit speed (V_limit), in which the selection means (24) classifies objects of an expanded category as possible obstacles , characterized by a recognition device (26) for recognizing following travel, wherein a vehicle traveling in front is followed as a target object, and a determination device for determining a limit speed (V_limit) according to the driving state recognized by the recognition device (28).

Description

Background technique [0001] The invention relates to a device for controlling speed and distance in a motor vehicle, with a positioning system for determining the orientation of an object in the front area of ​​the vehicle, for selecting an object whose orientation has been determined as a target object for controlling the distance The regulator and selection device, and with the low-speed driving function which is only useful below the limit speed, in this function, the selection device classifies an expanded category of objects as possible obstacles. [0002] This device is also known as Adaptive Speed ​​Control, or ACC (Adaptive Navigation Control) and, for example, when driving on the highway, the speed of the car can be adapted in such a way that, in following driving, with a suitable safety Distance to follow the car driving ahead. For this purpose, during free driving, ie when the position of the vehicle driving ahead is not detected in the own lane, the desired speed ...
