Passenger state estimation system and in-vehicle apparatus

A passenger state estimation system, comprising:

• an in-vehicle apparatus configured to include
• a crash determination unit configured to determine whether a crash has occurred to a vehicle having the in-vehicle apparatus installed, by using an in-vehicle sensor,
• a recording execution unit configured,
• if the crash determination unit determines that a crash has occurred to the vehicle, to have an in-vehicle recording medium record data of at least one of passenger information, vehicle operation information, and a degree of the crash, the data having been generated when the crash occurs, and
• a transmitter unit configured to transmit the data externally;
• and
• a center configured to include
• a receiver unit configured to receive the data transmitted from the transmitter unit of the vehicle, and
• a passenger estimation unit configured to estimate a state of a passenger of the vehicle, based on the data received by the receiver unit,
• wherein if the crash determined to have occurred to the vehicle by the crash determination unit is a crash requiring airbag deployment, and crashes including a crash not requiring airbag deployment have been determined to have occurred prior to the crash requiring airbag deployment within a predetermined time period, by the crash determination unit, the transmitter unit transmits the data generated when the crash requiring airbag deployment has occurred, and the data generated when the crashes including the crash not requiring airbag deployment have occurred, to the center,
• wherein the passenger estimation unit estimates the state of the passenger of the vehicle, based on the data generated when the crash requiring airbag deployment has occurred, and the data generated when the crashes including the crash not requiring airbag deployment have occurred.
