Driving assistance system and driving assistance method
First Claim
1. A driving assistance system comprising:
- a computer programmed to;
acquire operations by a driver, a vehicle behavior, a state of the driver, and information regarding an environment surrounding a vehicle as driving information from an in-vehicle network, an imaging device installed in front of a driver'"'"'s seat and a ranging sensor;
acquire vehicle location information from an in-vehicle navigation system;
generate statistical information by statistically processing the driving information as a time-series pattern;
calculate a transition probability from a temporally preceding driving information pattern to a temporally following driving information pattern, and generate map information by associating the statistical information and the transition probability with the vehicle location information at the time of the acquisition of the driving information;
reference and read the map information based on the transition probability and the location information;
perform driving assistance based on the map information; and
transceiver that transmits and receives information to and from a communication device outside the vehicle,wherein the information acquired by the transceiver is provided as the driving information for using the information acquired by the transceiver as the driving information and generating the statistical information, andwherein the computer generates a driving operation amount, that comprises at least one of a steering wheel amount, an accelerator amount, and a brake amount, from the statistical information and presents the driving operation amount to the driver.

Abstract
A driving assistance system has a driving information acquisition unit that acquires any of an amount of operations by a driver, a vehicle behavior, a state of the driver, and information regarding the environment surrounding a vehicle as driving information, a vehicle location information acquisition unit that acquires vehicle location information, a statistical information generation unit that generates statistical information by statistically processing the driving information as a time-series pattern, an information associating unit that associates the statistical information with the vehicle location information at the time of the acquisition of the driving information, an information reference unit that references and reads the statistical information based on the location information acquired by the vehicle location information acquisition unit, a driving assistance unit that performs driving assistance based on the statistical information read by the information reference unit, and a communication unit.
