A system includes: a server configured to transmit map data of each of areas; and a vehicle including a storage device. In a case where map data of an area to which a current position of the vehicle belongs is not stored in the storage device, the vehicle transmits, to the server, an acquisition request to acquire map data of an acquisition area including at least the area and stores the map data of the acquisition area that is transmitted in response to the acquisition request in the storage device. In a case where a frequency index value is equal to or less than a predetermined threshold, when a predetermined condition is established, the vehicle deletes the map data of the acquisition area. In a case where the frequency index value is larger than the threshold, the vehicle maintains the map data of the acquisition area to be stored.

Map data usage system, map data usage method, and program

An electronic control unit is a control device for controlling a vehicle including a vehicle speed sensor. The electronic control unit is configured to identify a section from start to stop of the vehicle using a vehicle speed detected by the vehicle speed sensor, determine whether the number of times of a low-speed section is more than a prescribed number of times, the low-speed section being the identified section where a representative value of the vehicle speed is less than a prescribed speed, and determine that the vehicle is in a specific situation where low-speed travel is inevitable, when it is determined that the number of times of the low-speed section is more than the prescribed number of times.

Control device, control method, and vehicle

A vehicle control apparatus includes an engine configured to drive a vehicle; a starter configured to start the engine; a headlamp configured to radiate light in front of the vehicle; a battery configured to supply driving electric power to the starter and the headlamp; a brightness detection unit configured to detect a physical quantity corresponding to brightness around the vehicle; and a control unit configured to have the engine stop automatically when a predetermined stopping condition is satisfied, and to have the engine start automatically when a predetermined starting condition is satisfied. The control unit inhibits the engine from stopping automatically when the headlamp is lighted, and the physical quantity detected by the brightness detection unit is less than or equal to a predetermined threshold.

Vehicle control apparatus

A fuel control apparatus for a vehicle, having an electric pump configured to have electric power supplied, to supply fuel from a fuel tank to an injector of an internal combustion engine through a fuel pipe, and a control unit configured to have the internal combustion engine stop automatically when a first predetermined condition is satisfied, and after having the internal combustion engine stop automatically, start automatically when a second predetermined condition is satisfied, includes an operation unit configured, when the control unit has the internal combustion engine stop automatically, to supply electric power from a predetermined electric power supply apparatus to the electric pump, to have the electric pump operate.

Fuel control apparatus for vehicle and fuel control method for vehicle

A vehicular control apparatus performs control of enabling idle operation of an internal combustion engine that generates a motive power applied to a driving wheel of a vehicle if a vehicle speed of the vehicle is lower than a predetermined vehicle speed that is set in advance, and disabling idle operation of the internal combustion engine if the vehicle speed of the vehicle is equal to or higher than the predetermined vehicle speed, when the vehicle is in a state other than an acceleration running state. Accordingly, the vehicular control apparatus achieves an effect of making it possible to suppress the consumption of fuel.
