Abstract
An information processing device calculates a feature related to driving of a driver. The information processing device includes: a processor that calculates the feature; and a transmission unit that transmits the calculated feature to an outside. The processor identifies whether there is a predetermined situation in which a risk in relation to a preceding vehicle occurs, and calculates, as the feature, information related to a behavior of the driver for reducing the risk when the predetermined situation is identified.
Claims7
An information processing device configured to calculate a feature related to driving of a driver, the information processing device comprising:
- one or more processors configured to calculate the feature;
- a reception unit configured to receive input information including at least one of information on driving operation of a vehicle, information on an operating state of driver assistance of the vehicle, and information on a behavior of the vehicle;
- and
- a transmission unit configured to transmit the calculated feature to an outside server,
- wherein the one or more processors are configured to:
- monitor an inter-vehicle time obtained by dividing an inter-vehicle distance from a preceding vehicle by a velocity related to a host vehicle;
- detect a change of the inter-vehicle time from being within a first predetermined range to being in a second, shorter predetermined range;
- identify, based on the detected change, that a predetermined situation in which a risk in relation to the preceding vehicle occurs, the predetermined situation occurring when the inter-vehicle time has reduced into the second range and continuing to occur only while the inter-vehicle time remains in the second range;
- and
- upon a determination that the predetermined situation is identified, calculate, as the feature, information related to a behavior of the driver for reducing the risk in the predetermined situation, the calculation being performed using only the input information received during a period beginning after the detected change of the inter-vehicle time into the second range and continuing while the inter-vehicle time remains in the second range.
A vehicle including an information processing device configured to calculate a feature related to driving of a driver, wherein:
- the information processing device includes
- one or more processors configured to calculate the feature;
- a reception unit configured to receive input information including at least one of information on driving operation of a vehicle, information on an operating state of driver assistance of the vehicle, and information on a behavior of the vehicle;
- and
- a transmission unit configured to transmit the calculated feature to an outside server;
- and
- the one or more processors are configured to:
- monitor an inter-vehicle time obtained by dividing an inter-vehicle distance from a preceding vehicle by a velocity related to a host vehicle;
- detect a change of the inter-vehicle time from being within a first predetermined range to being in a second, shorter predetermined range;
- identify, based on the detected change, that a predetermined situation in which a risk in relation to the preceding vehicle occurs, the predetermined situation occurring when the inter-vehicle time has reduced into the second range and continuing to occur only while the inter-vehicle time remains in the second range;
- and
- upon a determination that the predetermined situation is identified, calculate, as the feature, information related to a behavior of the driver for reducing the risk in the predetermined situation, the calculation being performed using only the input information received during a period beginning after the detected change of the inter-vehicle time into the second range and continuing while the inter-vehicle time remains in the second range.
An information processing system including a vehicle and an outside server, the vehicle including an information processing device configured to calculate a feature related to driving of a driver, wherein:
- the information processing device includes
- one or more processors configured to calculate the feature;
- a reception unit configured to receive input information including at least one of information on driving operation of a vehicle, information on an operating state of driver assistance of the vehicle, and information on a behavior of the vehicle;
- and
- a transmission unit configured to transmit the calculated feature to an outside server;
- and
- the one or more processors are configured to:
- monitor an inter-vehicle time obtained by dividing an inter-vehicle distance from a preceding vehicle by a velocity related to a host vehicle;
- detect a change of the inter-vehicle time from being within a first predetermined range to being in a second, shorter predetermined range;
- identify, based on the detected change, that a predetermined situation in which a risk in relation to the preceding vehicle occurs, the predetermined situation occurring when the inter-vehicle time has reduced into the second range and continuing to occur only while the inter-vehicle time remains in the second range;
- and
- upon a determination that the predetermined situation is identified, calculate, as the feature, information related to a behavior of the driver for reducing the risk in the predetermined situation, the calculation being performed using only the input information received during a period beginning after the detected change of the inter-vehicle time into the second range and continuing while the inter-vehicle time remains in the second range;
- and
- the outside server is configured to execute a predetermined process on the calculated feature.
