GEAR-SHIFT CONTROL DATA GENERATION METHOD, GEAR-SHIFT CONTROL DEVICE, AND GEAR-SHIFT CONTROL SYSTEM

A gear-shift control data generation method executed by an execution device in a state where relational regulation data used for regulating a relationship between a state of a vehicle and an action variable associated with an operation of a transmission (26) is stored includes a process for acquiring the vehicle state, a process for operating the transmission (26), a process for assigning, based on the vehicle state, a higher reward when a characteristic of the vehicle satisfies a criterion than when the characteristic does not satisfy the criterion, and a process for updating the relational regulation data by inputting, to an update mapping, the vehicle state, a value of the action variable, and a reward corresponding to the operation. The update mapping outputs the relational regulation data that is updated to increase an expected profit for the reward when the transmission (26) is operated according to the relational regulation data.
