The vehicle control device includes an arithmetic processing circuit configured to estimate a deterioration degree of a power transmission system component provided in a power transmission path between a drive source and wheels of a vehicle. The arithmetic processing circuit is configured to execute torque limit control that reduces an upper limit value of output torque of the drive source based on a scheduled maintenance date of the vehicle after a current date and an estimated value of the deterioration degree.

Vehicle control device

An information processing device includes: a communication unit configured to communicate with a vehicle used by a user; and a control unit configured to receive user information on the user via the communication unit, determine a usage mode of the vehicle according to a use purpose of the vehicle, the use purpose being estimated based on the user information, and send usage mode information on the usage mode to the vehicle via the communication unit.

Information processing device, information processing method, and non-transitory recording medium storing program

A control device of a vehicle with a stepped automatic transmission has: a gradient acquiring part; a driving force calculating part; a future change estimating part; and a shift control part. The shift control part prohibits change of the gear stage when the speed of change of the speed or acceleration of the vehicle in the future if the maximum driving force applied, is within a reference range of speed of change where the occupants would not notice a change in speed or acceleration, and permits change of the gear stage when the speed of change of the speed or acceleration of the vehicle in the future if the maximum driving force applied, is outside the reference range of speed of change.

Control device of vehicle

Automatic transmission control system and control method have the functions or steps of: controlling shifting of an automatic transmission installed on a vehicle, in one of an automatic shift mode in which shifting of the automatic transmission is carried out based on a shift diagram, and a manual shift mode in which shifting of the automatic transmission is manually carried out; detecting at least one shift command of an upshift command for shifting up the automatic transmission and a downshift command for shifting down the automatic transmission, the shift command being manually entered; measuring a shift command time for which the shift command is detected; and switching from the automatic shift mode to a shift inhibition mode in which shifting of the automatic transmission is inhibited, without switching to the manual shift mode, based on the measured shift command.
