Remote operation method, remote operation device, and non-transitory computer-readable recording medium

A remote operation device that remotely operates a vehicle in accordance with an operation of a remote operation member by an operator, wherein

• a first operation amount is an operation amount of the remote operation member by the operator,
• a first maximum operation range is a maximum operation range of the remote operation member, and
• a second maximum operation range is a maximum operation range of an operation member of the vehicle,
• the remote operation device comprising one or more processors programmed to execute:
• transmitting information of a second operation amount corresponding to the first operation amount to the vehicle via communication, wherein the vehicle is operated in accordance with the second operation amount;
• based upon a determination that the first maximum operation range is not equal to the second maximum operation range,
• a first adjustment process that, when the first maximum operation range is smaller than the second maximum operation range, adjusts a correspondence relationship between the first operation amount and the second operation amount such that the second operation amount becomes larger than the first operation amount;
• and
• a second adjustment process that, when the first maximum operation range is larger than the second maximum operation range, adjusts the second operation amount to be in the second maximum operation range, wherein
• a first maximum operation amount is a maximum operation amount in the first maximum operation range,
• a second maximum operation amount is a maximum operation amount in the second maximum operation range, and
• the first adjustment process includes adjusting the correspondence relationship between the first operation amount and the second operation amount such that the second operation amount corresponding to the first maximum operation amount is equal to the second maximum operation amount.
