HYBRID VEHICLE

摘要

When a starting point water temperature Twst is equal to or lower than a threshold value Twref1, catalyst warm-up control is executed, and when a cooling water temperature Tw becomes higher than the threshold value Twref1 or an operation time top of an engine becomes equal to or higher than a threshold value topref1, the control of the engine is shifted from the catalyst warm-up control to normal control. When the starting point water temperature Twst is higher than the threshold value Twref1 and is equal to or lower than a threshold value Twref2, PN suppression control is executed, and when the cooling water temperature Tw of the engine becomes higher than the threshold value Twref2 or the operation time top of the engine becomes equal to or higher than a threshold value topref2, the control of the engine is shifted from the PN suppression control to the normal control.

主权项

1. A hybrid vehicle by comprising:
an engine and a motor for driving; a battery that exchanges power with the motor; a controller configured to control the engine and the motor so that the engine is driven depending on a required output for driving while being intermittently operated, wherein the control controller, executes normal control in which the engine is controlled so that a target output of the engine according to the required output is output from the engine when a starting point water temperature that is a cooling water temperature at the start of the operation of the engine is higher than a second predetermined temperature higher than a first predetermined temperature, executes first control in which the engine is controlled so that an output of the engine is limited to a first predetermined output or lower and a catalyst of an exhaust gas control apparatus of the engine is warmed up when the starting point water temperature is equal to or lower than the first predetermined temperature, and then shifts to the normal control when the cooling water temperature becomes higher than the first predetermined temperature or when a first predetermined time has lapsed from the start of the operation of the engine, and executes second control in which the engine is controlled so that the output of the engine is limited to a second predetermined output or lower that is greater than the first predetermined output and a discharge amount of particulate matter from the engine is suppressed when the starting point water temperature is higher than the first predetermined temperature and is equal to or lower than the second predetermined temperature, and then shifts to the normal control when the cooling water temperature becomes higher than the second predetermined temperature or when a second predetermined time has lapsed from the start of the operation of the engine.
