Driver assistance system for maintaining speed or distance to ahead-driving vehicle, has controller, where constant moment is made during transition to condition and moment corresponding to actual moment before transition to condition

摘要

#CMT# #/CMT# The system has an electronic controller controlling a drive system and/or a brake system based on control of an offset related to speed or distance of an ahead-driving vehicle. Exceedance of the distance to a lower offset limit is changed depending on defined driving conditions in a consumption-optimized traction mode with increased offset. Constant drive moment is made during transition to consumption-optimized condition, where the moment corresponds to an actual drive moment before transition to the consumption condition. #CMT# : #/CMT# An independent claim is also included for a method for keeping given speed or given distance to the ahead-driving vehicle constant in a motor vehicle. #CMT#USE : #/CMT# Driver assistance system for use in a motor vehicle, for maintaining speed or distance to an ahead-driving vehicle. #CMT#ADVANTAGE : #/CMT# The design of the system reduces fuel consumption of the motor vehicle in an improved manner and ensures consumption-optimized control of the system, thus exactly maintaining speed of the vehicle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view illustrating a process of vehicle speed verses time in economic operation mode during speed regulation to target vehicle speed.'(Drawing includes non-English language text)'.
