    Abstract: A taxi vehicle management method includes: evaluating, based on DR contribution history information, a degree of contribution to demand response for energy management by a driver of a taxi vehicle, the DR contribution history information indicating a history of contribution to the DR by the driver using a power storage device of the taxi vehicle; and determining a calculation formula of a fare of the taxi vehicle driven by the driver, using a result of evaluation of the degree of contribution by the driver. The determining the calculation formula of the fare includes determining the calculation formula of the fare such that the fare becomes lower as the degree of contribution to the DR by the driver becomes higher.

    Abstract: The vehicle includes a driving operation member that is operated by an operator to perform steering, acceleration, and deceleration, a stop maintaining device that maintains a stop state, and a control device. In the remote control mode, the control device communicates with the remote operation target vehicle, transmits information reflecting the operation amount of the driving operation member to the remote operation target vehicle, and presents information received from the remote operation target vehicle to the operator. When the stop state of the vehicle is not maintained by the stop maintaining device, the control device prohibits the remote control mode.
