Abstract

A distance regulating system is disclosed for the automatic adjusting of a distance of a motor vehicle to a motor vehicle travelling ahead. At least one sensor detects the distance to the motor vehicle travelling ahead. A route detector detects a route section lying ahead. A control unit is equipped in order to transmit acceleration commands to a drive of the motor vehicle, to accelerate with a preset acceleration upon increasing distance to the motor vehicle travelling ahead or during open straight-ahead travel. The control unit can determine a. transverse acceleration to be expected and adjust a longitudinal acceleration as a function of the transverse acceleration to be expected when a curve lying ahead is detected by the route detection.

First claim

1 - 9 . (canceled)

10 . A distance regulating system for the automatic adjusting of a distance of an own vehicle to another vehicle travelling ahead of the own vehicle, the distance regulating system comprising:
at least one sensor for detecting the distance to the other motor vehicle travelling ahead; a route detection system for determining a route section lying ahead of the own vehicle; and a control unit configured to communicate an acceleration command to a drive of the own vehicle; wherein the acceleration command is communicated to the drive based on a preset acceleration for accelerating the own vehicle with a preset acceleration when the distance to the other vehicle is greater than a set distance and the route section is straight-ahead; and wherein a transverse acceleration is determined when the route section includes a curve lying ahead and the acceleration command is communicated to the drive based on the longitudinal acceleration as a function of the transverse acceleration.

11 . The distance regulating system according to claim 10 , wherein the route detection system comprises a camera for capture a road image, and the control unit is configured to determine the route section from the road image.

12 . The distance regulating system according to claim 10 , wherein the control unit is configured to adjust the longitudinal acceleration in such a manner that it corresponds to a revised preset acceleration which is reduced as a function of the transverse acceleration.

13 . The distance regulating system according to claim 10 , wherein the control unit is configured to communicate the acceleration command is based on a constant total acceleration.

14 . The distance regulating system according to claim 10 , wherein the control unit is configured to use a circle of forces model for adapting the longitudinal acceleration.

15 . The distance regulating system according to claim 10 , wherein the control unit is configured to communicate the acceleration command for accelerating the own vehicle up to a speed target.

16 . A motor vehicle comprising a vehicle having a drive and a distance regulating system according to claim 10 in communication with the drive.

17 . A computer program product with a non-transitory computer-readable storage medium having commands embedded therein which when executed by a control unit comprises:
a distance regulating system for communicating acceleration commands transmittable to a drive of a motor vehicle; wherein the acceleration command is communicated to the drive based on a preset acceleration for accelerating the own vehicle with a preset acceleration when the distance to the other vehicle is greater than a set distance and the route section is straight-ahead; and wherein a transverse acceleration is determined when the route section includes a curve lying ahead and the acceleration command is communicated to the drive based on the longitudinal acceleration as a function of the transverse acceleration.

18 . The computer program product according to claim 17 , wherein the distance regulating system is configured to use a circle of forces model for adapting the longitudinal acceleration.
