Abstract

Abstract A platoon running control system which is able to recognize the position of a vehicle within a platoon and to appropriately respond to a change, for example, when another vehicle leaving the platoon. If the vehicle is not in a platoon running mode, a communication control ECU assigns an ID = 1 to the vehicle, and a vehicle control ECU operates the vehicle in an auto-drive mode based on a signal such as from a magnetic sensor or a CCD camera. During platoon-running mode, a light receiver receives data including ID information from a preceding vehicle, and the controlled vehicle is assigned an ID according to a rule in which the ID of the vehicle = ID of the preceding vehicle + 1 . Then, the vehicle starts platoon running using data from the preceding vehicle. When the system received information that the preceding vehicle will leave the platoon, platoon-leaving data is transmitted to the vehicle, which then transmits such data to the following vehicle. The vehicle changes its ID to 1 when it does not receive any more data from the preceding vehicle. In a case where its ID has been changed to 1 from 3 or greater, the vehicle accelerates so as to re-form the platoon.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 137 words
A running control system for controlling platoon-running installed on a vehicle, the system comprising: (a) receiving means for receiving data which is transmitted from a preceding vehicle; (b) transmitting means for transmitting data to a following vehicle; (c) identification code setting means for assigning to the vehicle an identification code indicating that it is a leading vehicle if the receiving means has not received data from the preceding vehicle, and an identification code obtained by converting the identification code of the preceding vehicle contained in the received data according to a predetermined rule, if the receiving means has received the data; and (d) control means for controlling vehicle running based on the identification code of the vehicle provided by the identification code setting means, wherein the identification code indicates the position of the vehicle within the platoon.
Claim 2
Dependent Claim 43 words
The running control system according to claim 1, wherein the identification code indicative of the leading vehicle is 1, and the predetermined rule is expressed by the following expression: Identification code of the vehicle = Identification code of the preceding vehicle + 1.
Claim 3
Dependent Claim 47 words
The running control system according to claim 1, wherein the control means controls the vehicle on the basis of the data from the preceding vehicle received by the receiving means, if the identification code of the vehicle is not the identification code indicative of the leading vehicle.
Claim 4
Dependent Claim 60 words
The running control system according to claim 1, wherein the control means controls the vehicle to accelerate and catch up with a currently preceding vehicle if the present identification code of the vehicle is indicative of the leading vehicle and the previous identification of the vehicle indicates that it was running in the third or later position within the platoon.
Claim 5
Dependent Claim 28 words
The running control system according to claim 1, further comprising: (e) communication control means for superimposing platoon-leaving information onto the data to be transmitted to the following vehicle.
Claim 6
Dependent Claim 40 words
The running control system according to claim 1, wherein the identification code setting means also assigns to the vehicle the identification code indicative of the leading vehicle, if the receiving means has received the platoon-leaving information from the preceding vehicle.
Claim 7
Dependent Claim 64 words
The running control system according to claim 1, wherein the control means determines whether or not the preceding vehicle which has left the platoon was the leading vehicle based on the previous identification code of the vehicle, and controls the vehicle to accelerate and catch up with a currently preceding vehicle if the vehicle which has left the platoon was not the leading vehicle.
