Abstract
An engine having a throttle valve, a filter for collecting an exhaust particulate matter from the engine, and a control device are provided, and the control device includes an acquisition unit for acquiring a temperature of the engine, a regeneration control unit for increasing an opening degree of the throttle valve as the temperature increases, and executing a regeneration control of the filter by a fuel cut. A vehicle comprising: a retard amount control unit that increases a retard amount of an ignition timing at a time of returning from the fuel cut as the temperature increases.
Claims2
A vehicle comprising:
- an engine including a throttle valve;
- a filter that collects an exhaust particulate matter from the engine;
- a motor provided on a power transmission path between the engine and a drive wheel;
- a torque converter including a lock-up clutch provided on the power transmission path between the motor and the drive wheel;
- and
- a processor, wherein
- the processor is configured to
- acquire a temperature of the engine,
- execute regeneration control of the filter through a fuel cut by increasing an opening degree of the throttle valve as the temperature increases, the regeneration control including (i) normal regeneration control for executing the fuel cut by engaging the lock-up clutch and (ii) auxiliary regeneration control for assisting rotation of the engine by the motor while executing the fuel cut by disengaging the lock-up clutch,
- increase a first opening degree of the throttle valve in the auxiliary regeneration control more than a second opening degree of the throttle valve in the normal regeneration control, and
- increase retard amount of an ignition timing at a time of returning from the fuel cut as the temperature increases.
