Abstract
In a vehicle and a vehicle control method, when conditions i) and ii) are satisfied, an electronic control unit is configured to control an internal combustion engine so as to delay starting of the internal combustion engine, which is based on a condition where a vehicle request power is greater than a start threshold value, in a first mode than that in a second mode. The condition i) is a condition in which the driving mode is the first mode and the condition ii) is a condition in which the vehicle request power requested by the vehicle is greater than the start threshold value. The start threshold value is a value with which the internal combustion engine in a stopped state is started.
Claims8
A vehicle comprising:
- a rotary electrical machine configured to generate a drive force for the vehicle;
- an internal combustion engine configured to generate the drive force for the vehicle;
- a power storage device configured to supply electric power to the rotary electrical machine;
- and
- an electronic control unit configured to control the rotary electrical machine and the internal combustion engine in any one driving mode out of a plurality of driving modes, the plurality of driving modes including a first mode and a second mode, the first mode being a mode in which the vehicle travels using the electric power of the power storage device without sustaining a state of charge of the power storage device, and the second mode being a mode in which the vehicle travels while sustaining the state of charge of the power storage device,
- when conditions i) and ii) are satisfied, the electronic control unit being configured to control the internal combustion engine so as to delay starting of the internal combustion engine, which is based on a condition where a vehicle request power is greater than a start threshold value, than that in the second mode:
- i) a condition in which the driving mode is the first mode;
- and
- ii) a condition in which the vehicle request power requested to the vehicle is greater than the start threshold value, wherein the start threshold value is a value with which the internal combustion engine in a stopped state is started.
A vehicle control method, in which the vehicle comprises a rotary electrical machine, an internal combustion engine, a power storage device, and an electronic control unit the rotary electrical machine and the internal combustion engine generate a drive force for the vehicle, and the power storage device generates a drive force for the rotary electrical machine, the vehicle control method comprising:
- controlling, by the electronic control unit, the rotary electrical machine and the internal combustion engine in any one driving mode out of a plurality of driving modes, the plurality of driving modes including a first mode and a second mode, the first mode being a mode in which the vehicle travels using the electric power of the power storage device without sustaining a state of charge of the power storage device, the second mode being a mode in which the vehicle travels while sustaining the state of charge of the power storage device;
- and
- controlling, by the electronic control unit, the internal combustion engine so as to delay starting of the internal combustion engine, which is based on a condition where a vehicle request power is greater than a start threshold value, than that in the second mode when conditions i) and ii) are satisfied:
- i) a condition in which the driving mode is the first mode;
- and
- ii) a condition in which the vehicle request power requested to the vehicle is greater than the start threshold value, wherein the start threshold value is a value with which the internal combustion engine in a stopped state is started.
