Embodiment Construction

[0018] figure 1 A schematic diagram of a motor vehicle 1 according to the invention is shown. The motor vehicle now initially has an ACC system 2 with a control device 3 designed to carry out an embodiment of the method according to the invention. Motor vehicle 1 also has an emergency braking system 4 which also includes a control device 5 for carrying out a further embodiment of the method according to the invention.

[0019] The two control devices are connected, in particular via the CAN bus, to other vehicle systems, in particular environmental sensors, from which they acquire the data necessary for their function and communicate with the system to be controlled, in particular the braking system and / or motor connection. Other vehicle systems can also include communication device 6 , which can be integrated, for example, in the radio system of motor vehicle 1 . Data from an external, stationary transmitter 7 , which is part of the server 8 , can be received via the commu...

Abstract

Method for operating a longitudinal driver assistance system of a motor vehicle (1), especially of an ACC system (2), which is designed to control the speed of a motor vehicle (1) to a desired speed in a free travel mode and/or keeps a controlled distance to a vehicle in front as the control object in a follow mode, at least one control parameter influencing control being adapted depending on at least one item of traffic information that describes traffic conditions on the currently traveled route, especially in the further course of the route, said information being received from an external transmitter (7,9).

Description

technical field [0001] The invention relates to a method for operating a longitudinally guided driver assistance system of a motor vehicle, in particular an ACC system, which is designed to control the speed of the motor vehicle to Desired speed and / or speed for controlling the motor vehicle in follow-up operation in order to maintain a control distance to a vehicle driving ahead as control target. Furthermore, the invention relates to a motor vehicle having such a driver assistance system. Background technique [0002] A longitudinally guided driver assistance system for a motor vehicle, which is known in various configurations, therefore essentially automatically controls the speed of the motor vehicle. The simplest embodiment of such a longitudinally guided driver assistance system is often referred to as a speed control arrangement (GRA) or a speed controller. Here, the speed of the motor vehicle is controlled to a desired speed which can be selected by the driver. Th...
