  • Publication number: 20180365998
    Abstract: In a driving assistance apparatus, a driving condition estimator estimates the condition of a driver in a host vehicle and generates driving condition information. A risk information generator detects risky behavior taken by the driver, and generates risk information in which a risky point at which the risky behavior is detected is associated with driving condition information that is generated by the driving condition estimator in a prescribed zone located back from the risky point in a traveling direction, for recordation of the risk information into a server. A presentation determination unit compares driving condition information generated by the driving condition estimator in the prescribed zone located back in a traveling direction from a risky point of the risk information, with driving condition information included in the risk information received from the server, thereby to determine whether to present the risk information.

  • Patent number: 9576061
    Abstract: An arithmetic operation unit receives a request to update a first data group during restoration using first history information and generates second history information indicating a history of updates. The arithmetic operation unit predicts a time taken until completion of restoration using the second history information on the basis of an amount of the second history information. The arithmetic operation unit compares the predicted time with a threshold and limits at least part of updates of the first data group during the restoration using the second history information on the basis of the comparison result.
