DRIVING ASSISTANCE INFORMATION GENERATION SYSTEM, DRIVING ASSISTANCE INFORMATION PROVISION APPARATUS, DRIVING ASSISTANCE INFORMATION GENERATION METHOD, AND COMPUTER READABLE MEDIUM
First Claim
1. A driving assistance information generation system to generate driving assistance information to be provided to a driver of a vehicle, comprising:
- a storage unit to store event data indicating a geographical position and one or more events that have occurred at that position in the past; and
a control unit to predict a position to be passed through by the vehicle at a future time point, based on a position of the vehicle and a speed of the vehicle, to set, as a geographical range of a size corresponding to the speed of the vehicle, a range to be passed through by the vehicle from the future time point onward, based on the position predicted and the speed of the vehicle, to extract, from the event data stored in the storage unit, information on one or more of the events that have occurred within the geographical range, and to aggregate the information extracted, thereby generating the driving assistance information.

Abstract
A danger information notification system (10) is a system to generate danger information (70) to be provided to a driver of a vehicle. A storage unit (23) of a server apparatus (20) stores danger reports (50) each indicating a geographical position and an event that has occurred at that position in the past. A control unit (21) of the server apparatus (20) extracts, from the danger reports (50) stored in the storage unit (23), information on one or more danger events that have occurred in a geographical range of a size corresponding to a speed of the vehicle, and aggregates the information extracted, thereby generating the danger information (70). This danger information (70) is transmitted to a vehicle-mounted apparatus (40) from the server apparatus (20) through a network (30), and is output by an information presentation unit (46).

19. A driving assistance information provision apparatus to provide driving assistance information to a driver of a vehicle, comprising:
-
a control unit to perform control to display the driving assistance information generated by aggregating, from event data indicating a geographical position and one or more events that have occurred at that position in the past, information on one or more of the events that have occurred within a geographical range of a size corresponding to a speed of the vehicle, wherein a position to be passed through by the vehicle at a future time point is predicted based on a position of the vehicle and the speed of the vehicle, and a range to be passed through by the vehicle from the future time point onward is set based on the position predicted and the speed of the vehicle, the geographical range being the range that is set.

20. A driving assistance information generation method of generating driving assistance information to be provided to a driver of a vehicle, comprising:
by a computer including a storage unit to store event data indicating a geographical position and one or more events that have occurred at that position in the past, predicting a position to be passed through by the vehicle at a future time point, based on a position of the vehicle and a speed of the vehicle, setting, as a geographical range of a size corresponding to the speed of the vehicle, a range to be passed through by the vehicle from the future time point onward, based on the position predicted and the speed of the vehicle, extracting, from the event data stored in the storage unit, information on one or more of the events that have occurred within the geographical range, and aggregating the information extracted, thereby generating the driving assistance information.

21. A non-transitory computer readable medium storing a driving assistance information generation program of generating driving assistance information to be provided to a driver of a vehicle, the program causing a computer including a storage unit to store event data indicating a geographical position and one or more events that have occurred at that position in the past to execute:
a control process to predict a position to be passed through by the vehicle at a future time point, based on a position of the vehicle and a speed of the vehicle, to set, as a geographical range of a size corresponding to the speed of the vehicle, a range to be passed through by the vehicle from the future time point onward, based on the position predicted and the speed of the vehicle, to extract, from the event data stored in the storage unit, information on one or more of the events that have occurred within the geographical range, and to aggregate the information extracted, thereby generating the driving assistance information.
