Information processing device, vehicle, and information processing system
A brake ECU executes a process including the steps of: acquiring input information; determining whether predetermined conditions are met; when the predetermined conditions are met, acquiring vehicle speed data; updating a vehicle speed frequency distribution using the acquired vehicle speed data; and sending the updated vehicle speed frequency distribution to a data center.
1 . An information processing device that calculates an amount of characteristic relating to a driving characteristic of a driver of a vehicle, the information processing device comprising:
an electronic control unit that includes a processor, the electronic control unit being configured to:
acquire an amount of operation of the vehicle;
identify a predetermined driving state during travel of the vehicle using the amount of operation that has been acquired; and
calculate the amount of characteristic in the predetermined driving state, wherein
the predetermined driving state includes a driving state in which the vehicle is steered while moving straight ahead, and
the amount of characteristic includes a time-integrated value of a difference between a first steering amount that is estimated from a behavior of the vehicle and a second steering amount that is an actual amount steered.
2 . The information processing device according to claim 1 , wherein the electronic control unit is further configured to calculate a frequency distribution of the time-integrated value.
3 . A vehicle comprising the information processing device according to claim 1 .
4 . An information processing system comprising:
the information processing device according to claim 1 ; and
a server that manages information sent from the information processing device.
5 . The information processing device according to claim 1 , wherein the electronic control unit acquires data of the amount of operation of the vehicle from at least one sensor provided on the vehicle.
6 . The information processing device according to claim 1 , wherein the electronic control unit acquires data of the amount of operation of the vehicle from a memory in which is stored the data of the amount of operation of the vehicle obtained from at least one sensor provided on the vehicle.
7 . An information processing device that calculates an amount of characteristic relating to a driving characteristic of a driver of a vehicle, the information processing device comprising:
an electronic control unit that includes a processor, the electronic control unit being configured to:
acquire an amount of operation of the vehicle;
identify a predetermined driving state during travel of the vehicle using the amount of operation that has been acquired; and
calculate the amount of characteristic in the predetermined driving state, wherein
the predetermined driving state includes a driving state until the vehicle that is traveling is stopped, and
the amount of characteristic includes a difference between a peak value of a brake oil pressure and a mean value of the brake oil pressure after a peak.
8 . The information processing device according to claim 7 , wherein the electronic control unit is further configured to identify to which class the difference corresponds among a plurality of classes that is divided in order of a magnitude of the difference.
9 . A vehicle comprising the information processing device according to claim 7 .
10 . An information processing system comprising:
the information processing device according to claim 7 ; and
a server that manages information sent from the information processing device.
11 . The information processing device according to claim 7 , wherein the electronic control unit acquires data of the amount of operation of the vehicle from at least one sensor provided on the vehicle.
12 . The information processing device according to claim 7 , wherein the electronic control unit acquires data of the amount of operation of the vehicle from a memory in which is stored the data of the amount of operation of the vehicle obtained from at least one sensor provided on the vehicle.
