Problems solved by technology

[0004] However, the conventional platooning assisting device is based on the premise of using magnetic markers to determine the lateral displacement of vehicles on the road surface, so there is a problem that platooning can only be controlled on a limited road where magnetic markers are buried on the driving road.
In addition, there is a problem that the position of the vehicle cannot be determined with high precision

Embodiment approach 1

[0019] figure 1 It is a configuration diagram showing the platooning assistance device in Embodiment 1 according to the present invention. figure 1 It shows a state in which a plurality of vehicles 10 form a platoon and automatically travel on the road 100 , and behind the leading vehicle 10 a traveling at the head of the platoon, subsequent vehicles 10 b and 10 c sequentially travel in sequence. In addition, the number of vehicles forming the platoon may be two, or four or more.

[0020] The front vehicle 10 a is equipped with the sensor unit 1 , the road-to-vehicle communication device 7 , the vehicle-to-vehicle communication device 3 for transmission, and the processor unit 11 . The subsequent vehicle 10 b is equipped with a vehicle-to-vehicle communication device 3 for transmission, a vehicle-to-vehicle communication device 4 for reception, a processor unit 12 , and a sensor unit 2 . The following vehicle 10 c is equipped with a transmitting vehicle-to-vehicle communicat...

Abstract

The present application relates to a train-of-vehicle travel support device comprising: a reference data distribution device (15) adapted to distribute reference data including a three-dimensional position and data of a shape of a road surface; a preceding-vehicle-mounted sensor unit (1) obtaining road line shape data including a three-dimensional position and data of a shape of a feature on the road surface; a preceding-vehicle-mounted processor unit (11) obtaining running control data of a preceding vehicle (10a) based on comparison of the road line shape data showing the three-dimensional position and the shape of the feature obtained by the preceding-vehicle-mounted sensor unit (1) and in the reference data which is stored in the preceding-vehicle-mounted processor unit (15); an inter-vehicle communication device (3) transmitting the running control data of the preceding vehicle (10a) obtained by the preceding-vehicle-mounted processor unit (11) to a following vehicle (10b); and a following-vehicle-mounted processor unit (12) obtaining running control data of the following vehicle (10b) based on the running control data of the preceding vehicle (10a) transmitted by the inter-vehicle communication device (3).

Description

technical field [0001] The invention relates to a platoon driving assistance device for assisting the running of a plurality of vehicles traveling in platoon. Background technique [0002] Conventionally, there is known a platoon driving assisting device as follows: a magnetic mark is buried in the center of the road on which the vehicle travels, a magnetic sensor of the vehicle detects the magnetism of the magnetic mark to determine the lateral displacement of the vehicle on the road surface, and the vehicle is automatically steered along the magnetic mark, thereby Control the platoon travel of multiple vehicles. The platoon driving assisting device exchanges data such as vehicle identification numbers and speeds by using wireless communication and optical communication between the vehicle in front and the following vehicle, so that automatic speed control and braking control can be performed on the following vehicle following the vehicle in front (such as , refer to Paten...
