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.

Claims

1. A driving assistance system comprising:

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 that transmits and receives information to and from a communication device outside the vehicle,

wherein the driving information acquisition unit provides the information acquired by the communication unit to the statistical information generation unit as the driving information for using the information acquired by the communication unit as the driving information.

2. The driving assistance system according to claim 1,

wherein the driving information acquisition unit acquires more than one of the amount of operations by the driver, the vehicle behavior, the state of the driver, and the information regarding the environment surrounding the vehicle, and

wherein the driving assistance system further comprises:

an integrated pattern generation unit that associates the time-series patterns calculated using the driving information acquired by the driving information acquisition unit, as the time-series pattern acquired in the same environment.

3. The driving assistance system according to claim 1, wherein the statistical information generation unit divides the driving information for each section on a map, and calculates the time-series pattern for each section by using the driving information divided for each section.

4. The driving assistance system according to claim 1,

wherein the statistical information generation unit calculates the time-series pattern of the driving information regardless of sections on the map,

wherein the driving assistance system further comprises:

a pattern determination unit that determines to which one of a plurality of preset time-series patterns the time-series pattern calculated by the statistical information generation unit corresponds, and

wherein the information associating unit associates the driving information with the time-series pattern determined by the pattern determination unit.

5. The driving assistance system according to claim 1, further comprising:

an attribute provision unit that provides attributes to the driving information acquired by the driving information acquisition unit,

wherein the statistical information generation unit statistically processes the driving information as the time-series pattern, for each of the attributes provided by the attribute provision unit.

6. A driving assistance method comprising:

acquiring 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, and acquiring vehicle location information;

generating statistical information by statistically processing the driving information as a time-series pattern;

associating the statistical information with the vehicle location information at the time of the acquisition of the driving information;

referencing and reading the statistical information based on the acquired vehicle location information;

performing driving assistance based on the read statistical information; and

providing the information acquired by a communication unit configured to transmit and receive information to and from a communication device outside the vehicle as the driving information at generating the statistical information for using the information acquired by the communication unit as the driving information.
