Abstract

A system for assisting vehicle driving includes a processor executing a process of assisting vehicle driving; and a memory. The process includes communicating with vehicles to obtain the travel information, storing the travel information in the memory; estimating a target stop position where the vehicle should stop based on the travel information; transmitting the target stop position to the vehicles-obtaining an index indicating at least one of repeatability of driving behavior of a driver, proximity of the behavior to an average value of others, and fuel consumption, determining a first driver corresponding to the index indicating a value less than a value determined based on the travel information of others; and eliminating a stop position information form the travel information stored in the memory, the stop position information indicating a stop position based on the travel information of the vehicle driven by the first driver.

First claim

The invention claimed is:

1. A system for assisting vehicle driving, the system comprising:
a central server; and
a plurality of vehicles including a first vehicle,
wherein the central server includes:
a first processor,
a memory, and
a server communication device,
wherein each of the plurality of vehicles includes:
a second processor,
a car navigation system,
variable sensors, and
a vehicle communication device;
wherein the first processor and the second processor of each of the plurality of vehicles are configured to cooperate together to determine one or more target stop positions of the first vehicle, and wherein the system is configured to:
obtain, with the second processor, a travel information of the each of the plurality of vehicles by using the variable sensors, the travel information being an information in which a location indicated by a positional information obtained by the car navigation system is in association with an driving operation performed at the location,
collect the travel information, with the first processor, from each of the plurality of vehicles via the vehicle communication device and the server communication device and store the collected travel information into the memory,
refer to, with the first processor, the travel information obtained from the plurality of vehicles at one or more predetermined locations,
eliminate, with the first processor, the travel information related to a certain driver at the one or more plural predetermined locations from the memory in a case where at least one of following three conditions is satisfied:
when values indicating a driving operation performed by the certain driver vary more than a predetermined amount;
when a value indicating the travel information a vehicle of the certain driver differs from an average value of the travel information of the vehicles of other drivers by a predetermined amount or more; and
when a value indicating a fuel consumption of the vehicle of the certain driver is higher than an average value of the fuel consumption of the vehicles of the other drivers by a predetermined amount or more,
calculate, with the first processor, the one or more target stop positions for the first vehicle at the one or more predetermined locations based on the travel information stored in the memory, and
transmit, with the first processor, the calculated one or more target stop positions to the first vehicle as a drive assist information.

2. The system for assisting vehicle driving according to claim 1 , wherein the second processor of the first vehicle is configured to assist vehicle driving of the first vehicle based on the one or mere target stop positions received from the first processor.

3. The system for assisting vehicle driving according to claim 1 , wherein the driving operation includes an acceleration pedal operation and a brake pedal operation.
