Abstract

A vehicle, with an engine, includes an engine control unit configured to control the engine in a circuit mode in which a traveling performance of the vehicle is improved, on a basis of a request transmitted from a portable terminal, when the portable terminal operated by a user of the vehicle determines that a current position of the vehicle equipped with the engine is in a circuit, wherein the engine control unit is configured to reject switching to the circuit mode regardless of the request, when the engine control unit determines that a part of combustion conditions among all combustion conditions for stable combustion of fuel supplied to the engine in the circuit mode is not satisfied.

Claims (21)

1 . A vehicle with an engine, the vehicle comprising

an engine control unit configured to control the engine in a circuit mode m which a traveling performance of the vehicle is improved, on a basis of a request transmitted from a portable terminal, when the portable terminal operated by a user of the vehicle determines that a current position of the vehicle equipped with the engine is in a circuit,

wherein the engine control unit is configured to reject switching to the circuit mode regardless of the request, when the engine control unit determines that a part of combustion conditions among all combustion conditions for stable combustion of fuel supplied to the engine in the circuit mode is not satisfied, and

the engine control unit is configured to turn off the circuit mode, after the vehicle stops so as to stabilize behavior of the vehicle, in a case where the engine control unit determines that the part of the combustion conditions is not satisfied while the engine is controlled in the circuit mode and the vehicle is traveling.

2 . A vehicle with an engine, the vehicle comprising

an engine control unit configured to control the engine in a circuit mode in which a traveling performance of the vehicle is improved, on a basis of a request transmitted from a portable terminal, when the portable terminal operated by a user of the vehicle determines that a current position of the vehicle equipped with the engine is in a circuit; and

a display control unit configured to control display of a display device provided in a vehicle cabin of the vehicle,

wherein the engine control unit is configured to reject switching to the circuit mode regardless of the request, when the engine control unit determines that a part of combustion conditions among all combustion conditions for stable combustion of fuel supplied to the engine in the circuit mode is not satisfied,

the display control unit is configured to output a display requesting the vehicle to stop to the display device, on a basis of an instruction transmitted from the portable terminal, when the portable terminal determines that the current position of the vehicle is outside the circuit, and

the engine control unit is configured to turn off the circuit mode, after the vehicle stops so as to stabilize behavior of the vehicle.

3 . A vehicle with an engine the vehicle comprising

an engine control unit configured to control the engine in a circuit mode in which a traveling performance of the vehicle is improved, on a basis of a request transmitted from a portable terminal, when the portable terminal operated by a user of the vehicle determines that a current position of the vehicle equipped with the engine is in a circuit; and

a communication control unit provided in the vehicle and configured to control communication between the portable terminal and the engine control unit,

wherein the engine control unit is configured to reject switching to the circuit mode regardless of the request, when the engine control unit determines that a part of combustion conditions among all combustion conditions for stable combustion of fuel supplied to the engine in the circuit mode is not satisfied, and

the engine control unit is configured to turn off the circuit mode, when the engine control unit does not receive a signal transmitted from the communication control unit.

4 . A vehicle with an engine the vehicle comprising

an engine control unit configured to control the engine in a circuit mode in which a traveling performance of the vehicle is improved, on a basis of a request transmitted from a portable terminal, when the portable terminal operated by a user of the vehicle determines that a current position of the vehicle equipped with the engine is in a circuit,

wherein the engine control unit is configured to reject switching to the circuit mode regardless of the request, when the engine control unit determines that a part of combustion conditions among all combustion conditions for stable combustion of fuel supplied to the engine in the circuit mode is not satisfied,

the engine control unit is configured to exclude determination related to fail-safe control for the engine during a period from a first time to a second time,

the first time is a time when a starter for starting the engine is turned on, and

the second time is a time when a predetermined time elapses from a time when the starter is turned off.
