Cruise control system and method for vehicles
First Claim
1. A vehicle cruise control system for consumption-oriented control of a vehicle speed within a predefined desired speed range, the system comprising:
- an operating element for activating consumption-oriented speed control;
a control unit operatively coupled with the operating element, the control unit controlling the vehicle speed within the predefined desired speed range while taking into consideration a predefined maximum allowed energy consumption rate value when the consumption-oriented speed control is activated;
wherein the control unit is operatively configured such that an actual energy consumption rate value when the vehicle speed is within the predefined speed range does not exceed the predefined maximum allowed energy consumption rate value only as long as the vehicle speed is maintainable within the predefined desired speed range without exceeding the predefined energy consumption rate value.

Abstract
A vehicle cruise control system and method for consumption-oriented control of the vehicle speed within a predefined desired speed range includes an operating unit for activating the consumption-oriented speed control and a control unit, which controls the vehicle speed within the predefined desired speed range while taking into consideration a predefined maximum energy consumption value when the consumption-oriented speed control is activated. The vehicle speed is controlled in such a way that the predefined maximum energy consumption value is not exceeded only as long as a vehicle speed that lies within the predefined desired speed range is adjustable while taking into consideration the predefined energy consumption value.

13. A method of operating a vehicle cruise control system for consumption-oriented control of vehicle speed within a predefined desired speed range, the method comprising the acts of:
-
receiving an activation signal from an operating unit for activating the consumption-oriented speed control; receiving a signal indicative of a vehicle speed at a control unit; and controlling the vehicle speed with the control unit within the predefined desired speed range based upon a predefined maximum energy consumption rate value such that an actual energy consumption rate value when the vehicle speed is within the predefined speed range does not exceed the predefined maximum allowed energy consumption rate value only as long as the vehicle speed is maintainable within the predefined desired range without exceeding the predefined maximum energy consumption rate value. - View Dependent Claims (14, 15, 16, 17)
