Problems solved by technology

Unless the vehicle actually drives on such a road, the need for attention or ease of driving during the actual driving of the vehicle cannot be fully grasped
[0007] In other words, there is a risk that the above-mentioned navigation system may deviate from the actual environment and determine a road that cannot actually be considered as an easy-to-drive road as an easy-to-drive road
If such an incorrect determination result is used for vehicle control or route search, it may negatively affect vehicle driving characteristics, or may worry the driver

Abstract

A vehicular drive assist system that analyzes information collected from a vehicle and sends a result of analysis to the vehicle and / or another vehicle, including a vehicle-mounted apparatus (101) mounted in the vehicle, and a communication center (102) that communicates with the vehicle-mounted apparatus (101). The vehicle-mounted apparatus (101) detects a present position of the host vehicle, detects a vehicular state of the host vehicle, and sends the present position and the vehicular state at the position detected to the communication center (102). The communication center (102) performs statistic processing of the vehicular state received, separately for each predetermined area on a road, by using the present position, calculates a tendency of the vehicular state separately for each predetermined area, evaluates ease of travel on the road in the predetermined area from the tendency calculated, and sends a result of evaluation to the vehicle and / or another vehicle.

Description

Technical field [0001] The present invention relates to a vehicle driving assistance system that analyzes information collected from a vehicle and sends the analysis result to the vehicle and / or another vehicle, and in particular to a vehicle driving assistance system that improves the driving characteristics of the vehicle and the sense of safety of the vehicle driver System and vehicle driving assistance method. Background technique [0002] There are known systems and the like for predicting traffic congestion conditions based on the position information sent from the vehicle to the communication center (for example, see Japanese Patent Application Publication Nos. JP-A-2002-251698 and JP-A-2003-302229) . [0003] A navigation system that searches for a route while considering the ease of road driving is also known (for example, see Japanese Patent Application Publication No. JP-A-2003-279365). [0004] The above-mentioned system for predicting traffic congestion is a system t...
