The information processing device includes: an acquiring unit that acquires vehicle information including an acceleration of a vehicle and a detection time at which the acceleration is detected; a deriving unit that derives an amount of change of the acceleration per unit time using the vehicle information; a setting unit that sets a threshold value of the amount of change corresponding to an interval at which the acceleration is detected using the detection time; and an extracting unit that extracts the vehicle information corresponding to the amount of change as target data when the amount of change is equal to or larger than the threshold value.

Information processing device, information processing method, and storage medium

A wheel state obtaining system configured to obtain a wheel state that is a state of at least one of a plurality of wheels of a vehicle includes: a wheel speed detection device configured to detect a wheel speed of each of the plurality of wheels; a traveling state detection device configured to detect a traveling state of the vehicle; and a controller. When the traveling state of the vehicle detected by the traveling state detection device is a predetermined set state, the controller obtains a wheel speed difference of two of the plurality of wheels based on the wheel speeds of the plurality of wheels detected by the wheel speed detection device. The controller determines whether at least one of the two wheels is in an abnormal state based on the wheel speed difference.

Wheel state obtaining system and wheel state obtaining method

After the air pressure of the tire of the vehicle has decreased to a predetermined abnormal value, the system management server determines that the vehicle has returned to a normal value without performing a tire replacement operation or a tire repair operation (for example, there is a driver that continuously drives the vehicle by replenishing air without performing a tire replacement even if the tire is punctured), and transmits abnormality notification information to the administrator terminal device. Thus, the warning information is provided to the current driver of the vehicle by the operation of the administrator terminal device by the administrator.

Vehicle state grasping system

A vehicle air conditioning system, including: a vehicle interior environmental information acquisition unit that acquires environmental information of a vehicle interior; a vehicle exterior environmental information acquisition unit that acquires environmental information of surroundings of the vehicle; a sensible temperature prediction unit that predicts a sensible temperature of an occupant of the vehicle after a predetermined amount of time has elapsed, based on the environmental information acquired by the vehicle cabin interior environmental information acquisition unit and the vehicle cabin exterior environmental information acquisition unit; and an air conditioner controller that controls an air conditioner based on information regarding a future sensible temperature of the occupant which has been predicted by the sensible temperature prediction unit and a comfortable sensible temperature of the occupant which is stored in a storage unit.

Vehicle air conditioning system and air conditioner control method

A road surface damage detection device is configured to calculate, for each of road sections, a maximum variation rate that is a maximum value of a variation amount of a wheel speed per unit time in each of vehicles. The device is configured to periodically select, for each of the road sections, a maximum value from the maximum variation rate of each of the vehicles in a prescribed period, set the selected maximum value as a section maximum variation rate, and determine whether or not the road surface damage has occurred by comparing a determination target value with a positive threshold, the determination target value being obtained by subtracting a comparison value, based on at least one of the section maximum variation rates set before last time, from the section maximum variation rate that is set latest.

Road surface damage detection device, road surface damage detection method, and program

A road surface condition estimation apparatus () is provided with a collecting device () for collecting, from vehicle (), behavior information relating to a behavior of the vehicle; a determining device () for determining on the basis of the behavior information whether or not an abnormality condition is satisfied, the abnormality condition being set on the basis of a specific behavior that is expected to be taken by the vehicle when the vehicle encounters a road surface abnormality; and an estimating device () for estimating a condition of the road surface on the basis of a determined result of the determining device.
