  • Publication number: 20230140698
    Abstract: A power supply system includes a vehicle equipped with a battery, a power supply device, and a control device that controls power supply from the power supply device to the vehicle. The vehicle includes an engine and a motor that receives the power supplied from the battery to generate traveling drive force. When the power supply by the power supply device is requested from the vehicle, the control device (a) acquires a remaining amount of fuel for the engine from the vehicle, (b) outputs an instruction to urge the vehicle to shorten a charging time when the remaining amount of fuel is larger than a reference value, and (c) sets at least one of a unit price for charging power or a unit price for fuel lower when a response to accept the instruction is received from the vehicle compared with when the instruction is not accepted.

  • Publication number: 20230083650
    Abstract: A communication device acquires schedule information in which a schedule of a user who uses a hybrid electric vehicle is recorded. The schedule information includes a traveling schedule for causing the hybrid electric vehicle to travel in a predetermined period. The predetermined period is a period from when fuel of an engine is refueled to a predetermined deterioration time. When a traveling distance in a long-distance traveling schedule is a first distance, an ECU increases a usage ratio of the engine in the predetermined period than when the traveling distance is a second distance that is longer than the first distance. The long-distance traveling schedule is a schedule included in the traveling schedule and in which the hybrid electric vehicle travels for a predetermined distance or longer.

  • Publication number: 20220291003
    Abstract: A ridesharing management system which enables a plurality of users using a ridesharing service to share a vehicle as passengers, wherein the vehicle is comprised of a hybrid vehicle, and a boundary is established between the inside of an engine restricted zone in which operation of an internal combustion engine is restricted and the outside of the engine restricted zone. It is predicted whether the SOC amount of the battery will become less than a setting value during travel in the engine restricted zone if traveling through a stop in the engine restricted zone and a stop outside the engine restricted zone due to a pick-up request or drop-off request from a user. A route order that does not result in the SOC amount of the battery becoming less than the setting value during travel in the engine restricted zone is suggested.
