Embodiment Construction

[0021] figure 1 An example scenario is shown in which the method according to the invention can be used. Immediately in front of the ego vehicle 10 there are two vehicles 11 , 12 on the lane C, which are each equipped with a device for vehicle-to-vehicle communication and for carrying out a platoon start by means of an electronic traction system. To this end, the vehicle 11 transmits the wireless signal S 11 And the vehicle 12 transmits the wireless signal S 12 Sent to ego vehicle 10. It is also given to vehicle 11 by means of driving direction indicator 6 that vehicle 11 intends to make a (permitted) turning process to the right. Between the traffic light system 1 and the ego vehicle 10 there is a distance d which is ascertained by means of environmental sensors (not shown) and by means of a localization analysis in conjunction with a digital road map of the ego vehicle 10 . Wireless signal S of signal lamp device 1 1 The vehicles 10 , 11 , 12 , 20 , 21 , 22 , 30 , 31 , ...

Abstract

A forward movement, a device and a method for accelerating a vehicle (10) at a signal light device (1) at the start of a queue are proposed. The method includes the following steps: determining the probability that a predefined vehicle (10) can pass the traffic light device (1) during a real-time or upcoming green light phase, as long as the probability is greater than a predefined threshold, corresponding to the electronic The signals (S1, S11, S12, S22) of the traction system accelerate the vehicle (10) and to a correspondingly lesser extent as long as the probability is smaller than a predefined threshold.

Description

technical field [0001] The present invention relates to a forward motion, device and method for accelerating a vehicle when starting at a signal light arrangement. In particular, the invention relates to performing traffic light activation as comfortably and energy-efficiently as possible with an electronic traction system. Background technique [0002] Distance adjustment systems belong to the prior art and can be used in many vehicles at the same time. Furthermore, these systems (so-called stop-start systems) can sometimes slow down to a standstill and start again from a standstill. When starting automatically at a traffic light, the number of vehicles passing the traffic light during the green phase also depends on how quickly those vehicles move. The lower the acceleration and the longer the reaction time, the fewer vehicles will be able to pass the traffic light within a given duration of the green phase. Against this background, the so-called "electronic traction" (...
