METHOD AND SYSTEM FOR ADAPTIVE CRUISE CONTROL AND VEHICLE

摘要

A method for adaptive cruise control of a host vehicle (2): A host vehicle (2) includes at least one acceleration device (8), at least one retardation device (10), a control unit (14) for acting upon the acceleration device (8) and the retardation device (10), a calculating unit (16) for determining at least one parameter related to a lead vehicle (6) and a distance sensor (12) for determining a distance from the host vehicle to the lead vehicle (6). The method includes the steps of: setting a first predetermined time distance between the host vehicle (2) and the lead vehicle (6), maintaining the first predetermined time distance, evaluating a parameter that characterizes velocity changes of the lead vehicle in order to optimize a time distance between the host vehicle (2) and the lead vehicle (6), changing the first predetermined time distance to a second predetermined time distance if the parameter that characterizes velocity changes reaches a threshold value, and maintaining the second predetermined time distance. A system, a vehicle, a computer program product and a computer program for the method are further described herein.

1. A method for adaptive cruise control of a host vehicle (2), which host vehicle (2) comprises at least one acceleration device (8), at least one retardation device (10), a control unit (14) for acting upon the acceleration device (8) and the retardation device (10), a calculating unit (16) for determining at least one parameter related to a lead vehicle (6), and a distance sensor (12) for determining a distance to the lead vehicle (6) wherein the method comprises the steps of:
setting (100) a first predetermined time distance between the host vehicle (2) and the lead vehicle (6) in the control unit (14), and maintaining (102) the first predetermined time distance by acting upon the acceleration device (8) and the retardation device (10) by means of the control unit (14), characterized in that the method further comprises the steps of: evaluating (104), in the calculating unit (16), a parameter that characterizes velocity changes of the lead vehicle (6) while maintaining the first predetermined time distance in order to optimize a time distance between the host vehicle (2) and the lead vehicle (6), changing (106) the first predetermined time distance to a second predetermined time distance between the host vehicle (2) and the lead vehicle (6) in the control unit (14) if the parameter that characterizes velocity changes reaches a threshold value, and maintaining (108) the second predetermined time distance by acting upon the acceleration device (8) and the retardation device (10) by means of the control unit (14).
