Abstract

Method for operating a longitudinal driver assistance system (13) of a motor vehicle (12) which is designed to regulate the speed of the motor vehicle (12) to a control speed, wherein—depending on environment data describing the operating environment in which the motor vehicle (12) is currently operated—the control speed can be changed from a desired speed (3) provided by a driver to a target speed (5) (which is provided for an upcoming operating environment (2) and/or can be determined from the environment data), wherein, when there is a change of the desired speed (3) to a new target speed (5) for an upcoming operating environment (2), for a predetermined time period and/or a predetermined distance in the upcoming operating environment (2), an intermediate speed (6) deviating from the target speed (5) in the direction of the current speed of the motor vehicle (12) is initially regulated to, which intermediate speed (6) is between the current speed of the motor vehicle (12) and the target speed (5), before the target speed (5) is regulated to after the time period expires or before the distance is traversed.

Claims

1. A method, comprising:

operating a longitudinal driver assistance system of a motor vehicle which is designed to regulate the speed of the motor vehicle to a control speed, wherein—

depending on environment data describing the operating environment in which the motor vehicle is currently operated—

the control speed can be changed from a desired speed provided by a driver to a target speed (which is provided for an upcoming operating environment and/or can be determined from the environment data), when there is a change of the control speed to a new target speed for an upcoming operating environment, for a predetermined time period and/or a predetermined distance in the upcoming operating environment, an intermediate speed deviating from the target speed in the direction of the current speed of the motor vehicle is initially regulated to, which intermediate speed is between the current speed of the motor vehicle and the target speed, before the target speed is regulated to after the time period expires or before the distance is traversed.

2. The method according to claim 1, wherein an offset speed for the operating environment is adjustable by the driver, wherein—

after selection of an offset speed in the operating environment the target speed plus the offset speed is selected as a control speed instead of the target speed.

3. The method according to claim 1, wherein the intermediate speed is determined from a tolerance interval around the target speed as a corresponding limit of said target speed, and/or the intermediate speed is adjustable by the driver, especially in the form of a tolerance interval.

4. The method according to claim 1, wherein the intermediate speed is selected depending on the and/or additional environment data, and/or on the target speed and/or the current speed, and/or on other operating data of the motor vehicle.

5. The method according to claim 1, characterized in that wherein the intermediate speed is regulated to only from the side facing toward [sic] the current speed of the motor vehicle at the beginning of the regulation to the intermediate speed, or that a speed interval that is formed from the intermediate speed and the target speed is preferably regulated to.

6. The method according to claim 1, wherein the regulation to the intermediate speed takes place only after selection of a corresponding control option by the driver.

7. The method according to claim 1, characterized in that wherein the achievement of the intermediate speed is regulated upon reaching a boundary of the upcoming operating environment.

8. A motor vehicle comprising a longitudinal driver assistance system having a control unit designed for implementing a method according to claim 1.
