Abstract
Method for operating a longitudinal driver assistance system (2) of a motor vehicle (1), which controls, in a pure follow mode, the speed of the motor vehicle (1) such that a distance to a vehicle in front as the control object remains constant, and which, in a free travel mode, controls the speed to a desired speed, a likelihood of the vehicle (14) in front of pulling out being determined depending on sensor data of at least one ambient sensor. The control with respect to the vehicle (14) in front and/or the control in the free travel mode is modified or ended directly after termination of the follow mode depending on the pulling-out likelihood.

16. A method for operating a longitudinal driver assistance system of a motor vehicle, wherein the driver assistance system controls a speed of the motor vehicle in an exclusive follow mode so that a distance to a preceding vehicle representing a control object remains constant, and the driver assistance system controls the speed of the motor vehicle in a free-driving mode at a desired speed, the method comprising:
-
determining a pulling-out probability of the preceding vehicle as a function of sensor data of at least one environment sensor, and modifying control of the speed in relation to the preceding vehicle or in free-driving mode immediately upon termination of the follow mode depending on the pulling-out probability by at least one of reducing a control distance to the preceding vehicle and adding a positive acceleration value to an acceleration request determined by the driver assistance system in follow mode, when the pulling-out probability exceeds a preparation threshold value and when a speed of the preceding vehicle is lower than the desired speed, or by terminating the follow mode depending on the pulling-out probability by at least one of changing more quickly from braking to driving and requesting a greater acceleration than with another object deplausibilization, when the pulling-out probability exceeds a situation threshold value upon termination of the follow mode. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A motor vehicle comprising:
-
at least one environment sensor, and a longitudinal driver assistance system with a controller configured to control a speed of the motor vehicle in an exclusive follow mode so that a distance to a preceding vehicle representing a control object remains constant, and to control the speed of the motor vehicle in a free-driving mode at a desired speed, to determine a pulling-out probability of the preceding vehicle as a function of sensor data from the at least one environment sensor, and to modify or terminate control of the speed in relation to the preceding vehicle or in free-driving mode immediately upon termination of the follow mode depending on the pulling-out probability.
