Abstract
Regulation of a longitudinal acceleration of a main vehicle (10), particularly a truck, includes: detecting a driving behavior of vehicles traveling in front of a preceding vehicle that is traveling immediately in front of the main vehicle (10), regulating the longitudinal acceleration of the main vehicle (10) based on an evaluation of the driving behavior of the vehicles in such a way as to minimize energy consumption of the main vehicle (10).
Claims8
A method for regulating longitudinal direction acceleration of a main vehicle, the method comprising:
- detecting driving behavior of a procession of vehicles traveling in front of a preceding vehicle,
- wherein the preceding vehicle is traveling immediately in front of the main vehicle, and the procession of vehicles comprises a first vehicle remote from the main vehicle and at least one additional vehicle between the first vehicle and the main vehicle;
- determining future driving behavior of the preceding vehicle based on a statistical model that describes or models the driving behavior of the procession of vehicles in front of the main vehicle,
- wherein the statistical model includes statistical data obtained from headway distances between the first vehicle and the at least one additional vehicle;
- and
- regulating, according to the determining of the future behavior of the preceding vehicle, the longitudinal acceleration of the main vehicle by minimizing a frequency of stopping processes of the main vehicle in which the main vehicle comes to a complete stop.
A device for regulating longitudinal acceleration of a main vehicle, the device comprising:
- a sensor configured to detect driving behavior of a procession of vehicles traveling in front of a preceding vehicle that is traveling immediately in front of the main vehicle, the procession of vehicles comprising a first vehicle remote from the main vehicle and at least one additional vehicle between the first vehicle and the main vehicle;
- a controller configured to determine future driving behavior of the preceding vehicle based on a statistical model that describes or models the driving behavior of the procession of vehicles in front of the main vehicle,
- wherein the statistical model includes statistical data obtained from headway distances between the first vehicle and the at least one additional vehicle;
- and
- the controller configured to regulate, according to the determined future behavior of the preceding vehicle, the longitudinal acceleration of the main vehicle by minimizing a frequency of stopping processes of the main vehicle in which the main vehicle comes to a complete stop.
