Abstract
A vehicle includes an internal combustion engine, a catalyst provided in an exhaust passage of the internal combustion engine, and an electronic control unit. The electronic control unit is configured to control an engine torque such that a first torque change amount of the engine torque when the temperature of the catalyst belongs to a predetermined low temperature region to be lower than a second torque change amount of the engine torque when the temperature of the catalyst belongs to a high temperature region. The high temperature region is a region having a temperature higher than the low temperature region.
Claims8
A vehicle comprising:
- an internal combustion engine;
- a catalyst that is provided in an exhaust passage of the internal combustion engine;
- and
- an electronic control unit,
- the electronic control unit being configured to control an engine torque such that a first torque change amount of the engine torque to be lower than a second torque change amount of the engine torque,
- the first torque change amount being a torque change amount when a temperature of the catalyst belongs to a predetermined low temperature region, the second torque change amount being a torque change amount when the temperature of the catalyst belongs to a high temperature region, and the high temperature region being a region having a temperature higher than the low temperature region.
A control method of a vehicle,
- the vehicle including an internal combustion engine, a catalyst provided in an exhaust passage of the internal combustion engine, and an electronic control unit,
- the method comprising:
- controlling, by the control unit, an engine torque such that a first torque change amount of the engine torque to be smaller than a second torque change amount of the engine torque,
- the first torque change amount being a torque change amount when a temperature of the catalyst belongs to a predetermined low temperature region, the second torque change amount being a torque change amount when the temperature of the catalyst belongs to a high temperature region, and the high temperature region being a region having a temperature higher than the low temperature region.
