A method for determining a dynamic inter-vehicle distance between a following vehicle and a preceding vehicle in a group

摘要

The present invention is a method for determining a dynamic inter-vehicle distance Ayn between a group of subsequent vehicles FF and a preceding vehicle VF, and wirelessly transmits a V2V signal S1 between the following vehicle FF and the preceding vehicle VF. The method of determining at least the current maximum subsequent vehicle deceleration zMax_FF of the following vehicle FF and the time to transmit information to the subsequent vehicle FF that the preceding vehicle VF has started the emergency brake N. A transmission time of the vehicle, a step of determining the current maximum preceding vehicle deceleration zMax_VF of the preceding vehicle VF, and a step of determining the dynamic inter-vehicle distance Ayn from the difference sB between the transmission distance s and the braking distance. The transmission distance s represents the distance traveled by the succeeding vehicle FF between the start of the emergency brake N by the preceding vehicle VF and the start of the emergency brake N by the succeeding vehicle FF. This transmission distance s depends on the transmission time from time to time, and this braking distance difference sB is determined by the preceding vehicle braking distance w_VF given by the maximum preceding vehicle deceleration zMax_VF and the following vehicle braking distance w_FF given by the maximum succeeding vehicle deceleration zMax_FF. Represents the difference between.
