| 摘要 |
The invention concerns a device for longitudinally guiding a motor vehicle (10), comprising a speed sensor (12) for measuring the vehicle running speed, a distance sensor (14) for measuring the distance relative to an obstacle located more or less in front of the vehicle (10), and a regulator acting on the driving system and the braking system (20, 22) of the vehicle and adjusting the running speed, in a closed regulating loop, as the case may be, on the basis of the distance relative to the obstacle, insofar as the running speed is greater than a specific speed. The invention is characterized in that it comprises a control device (18) which operates so as to control the driving and braking systems (20, 22) in case the running speeds are lower than the threshold speed.
