Abstract

A speed control for motor vehicles having an input device for the input of a desired speed by the driver, and having a plurality of operating modes which are able to be activated in different speed ranges and differ in their functional scope. A decision unit is provided which automatically undertakes the switchover of the operating mode in the light of the actual speed of the vehicle.

Claims

1-7. -7. (cancelled).

8. A speed control for a motor vehicle comprising:

an input device for input of a desired speed by a driver;

a plurality of operating modes which are able to be activated in different speed ranges and differ in functional scope; and

a decision unit configured to automatically undertake a switchover of the operating mode as a function of an actual speed of the vehicle.

9. The speed control as recited in claim 8, further comprising:

a display device to display the operating mode.

10. The speed control as recited in claim 8, further comprising:

a signal device configured to signal to the driver a change in the operating mode.

11. The speed control as recited in claim 8,

wherein one of the operating modes is an operating mode for higher vehicle speeds that is able to be activated only above a limiting speed, and another of the operating modes is an operating mode for lower vehicle speeds which has a function for the automatic braking of the vehicle to a standstill and is able to be activated in a speed range whose upper limit is at least equal to the limiting speed.

12. The speed control as recited in claim 11, further comprising:

a decision unit configured to automatically cause a change from the mode for higher speeds into the mode for lower speeds when the actual speed of the vehicle is less than the limiting speed.

13. The speed control as recited in claim 11, wherein the decision unit causes a change from the mode for lower speeds into the mode for higher speeds when the actual speed is greater by h than the limiting speed, where h is a nonnegative value.

14. The speed control as recited in claim 11, wherein the decision unit activates the mode for greater speeds if, in response to the input of the desired speed the actual speed of the vehicle is greater than the limiting speed and the decision unit activates the mode for lower speeds if, in response to the input of the desired speed the actual speed of the vehicle is less than or equal to the limiting speed.
