Problems solved by technology
[0005] According to the control system related to the above-mentioned prior art, since the throttle opening of the following vehicle changes synchronously with the throttle opening of the leading vehicle, for example, even if the leading vehicle performs an inappropriate accelerator operation, the running state of the following vehicle will be changed. The driving state will also change according to the inappropriate accelerator operation, and the inappropriate driving state will spread among vehicles like a wave, which may cause traffic jams

Embodiment Construction
[0049] Next, an embodiment of the synchronized driving assistance device of the present invention will be described with reference to the drawings.
[0050] The synchronized driving assistance device 10 of the present embodiment is installed in, for example, a plurality of vehicles 2 to constitute a synchronized driving assistance system 1 .
[0051] The vehicle 2 can, for example, directly perform two-way communication with other vehicles 2 through inter-vehicle communication, or indirectly perform two-way communication with other vehicles 2 through wireless communication through a wireless communication network system such as a roadside communication device or a base station. .
[0052] In addition, the vehicle 2 can perform two-way communication with the server device 3 by, for example, road-to-vehicle communication (communication between the road side and the vehicle side) through roadside communication equipment or wireless communication with a wireless communication netw...

The synchronous driving assisting device according to the present invention has: a first acceleration power spectrum obtaining means which obtains a first acceleration power spectrum obtained from the acceleration of the first vehicle; a second acceleration power spectrum obtaining means which obtains a first acceleration power spectrum obtained from the acceleration of the second vehicle. The second acceleration power spectrum obtained by acceleration; the cross power spectrum calculation mechanism, which uses the first acceleration power spectrum and the second acceleration power spectrum to calculate the cross power spectrum between the first vehicle and the second vehicle; coherence A correlation calculation means calculates a coherence based on the cross power spectrum; a correlation evaluation means evaluates the correlation of the synchronous driving of the first vehicle and the second vehicle based on the coherence.
Description
technical field [0001] The invention relates to a synchronous driving assistance device and a synchronous driving assistance system. [0002] This application claims the priority of Japanese Invention Patent Application No. 2012-04176 filed on January 12, 2012 and Japanese Invention Patent Application No. 2012-089364 filed on April 10, 2012, and the contents thereof are cited here. Background technique [0003] In the prior art, a control system is known which controls the output of the following vehicle based on, for example, the information on the throttle opening of the leading vehicle, and the output of the two is controlled between the leading vehicle and the following vehicle. The power output changes are synchronized so that the inter-vehicle distance is kept constant (for example, refer to Patent Document 1). [0004] Patent Document 1: Japanese Invention Patent Laid-Open Publication No. 2008-155740 [0005] According to the control system related to the above-ment...
