The hybrid electric vehicle includes an engine, a motor generator, a clutch arranged between a crankshaft and the motor generator, and a catalyst arranged in an exhaust passage. The controller includes first processing circuitry that executes a catalyst warming process that warms the catalyst under a situation in which the hybrid electric vehicle is at a standstill and second processing circuitry configured to control the clutch and the motor generator. The first processing circuitry requests the second processing circuitry to prohibit disengagement of the clutch when the catalyst warming process is executed.

Hybrid electric vehicle controller and method for controlling hybrid electric vehicle

A controller controls a hybrid electric vehicle. The hybrid electric vehicle includes an engine, a motor arranged in a power transmission path between the engine and a drive wheel, and a clutch arranged in the power transmission path between the engine and the motor. The controller idles the engine in accordance with a target engine rotation speed and operates the motor in accordance with a target motor rotation speed when the clutch is in a disengagement state. When the clutch is in the disengagement state and the engine is idling, the target motor rotation speed is less than the target engine rotation speed.

Controller for hybrid electric vehicle and method for controlling hybrid electric vehicle

When a start request for an internal combustion engine is made with 1) a clutch disconnected, 2) a crankshaft rotating at a specified rotation speed or greater, and 3) fuel injection by an injector stopped, a controller for a vehicle executes: a first process that identifies, from the cylinders, a target cylinder that is in a compression stroke when the request is made; a second process that calculates a requested injection position based on the rotation speed; a third process that calculates, as a start crank position, a rotation position of the crankshaft advanced from the requested injection position by a specified rotation amount; and a fourth process that outputs a command signal that instructs a target injector to inject fuel at the crank position only if the rotation position of the crankshaft obtained when the request is made is advanced from the crank position.

Controller for vehicle and control method for vehicle

When the vehicle is stopped and removal of deposits is not required, and forced charging of a power storage device is not being performed, the controller controls the fuel supply device so that a supply fuel pressure is at the first fuel pressure. When the vehicle is stopped and the removal of deposits is required, and the forced charging of the power storage device is being performed, the controller controls the fuel supply device so that the supply fuel pressure is at a second fuel pressure higher than the first fuel pressure. When the vehicle is stopped and the removal of deposits is required, and the forced charging of the power storage device is not being performed, the controller controls the fuel supply device so that the supply fuel pressure is at a third fuel pressure higher than the first fuel pressure and lower than the second fuel pressure.

An internal combustion engine includes a port injection valve, a direct injection valve, and a forced-induction device. A ratio of an amount of fuel injected from the port injection valve with respect to a total amount of fuel supplied for one fuel combustion in the cylinder is defined as a port injection ratio. The internal combustion engine is controlled such that, in a case in which a condition is satisfied that the forced-induction device is in an operation of performing forced induction and the internal combustion engine is in an engine operation region in which a valve overlap period is greater than zero, the port injection ratio is set to be small and a start timing of fuel injection from the port injection valve is delayed as compared with a case in which the condition is not satisfied.

Controller and control method for internal combustion engine

A control device for a hybrid electric vehicle includes an electronic control unit. The electronic control unit is configured to perform a start-up control of shifting the connection and disconnection clutch to a coupled state at the time of starting the internal combustion engine to rotate the internal combustion engine by the driving torque of the electric motor, and starting the first fuel injection mode using the direct injection injector. The electronic control unit is configured to switch from the first fuel injection mode to a second fuel injection mode for using the port injector prior to an end of the start-up control when the number of times of combustion cycles of the internal combustion engine with the first fuel injection mode reaches a predetermined first target number of times.

Control device for hybrid electric vehicle

A vehicle controller includes processing circuitry. The processing circuitry is configured to perform an intermittent stop of an engine in accordance with a traveling state of a vehicle, cause the engine to restart by self-sustaining resumption when restart of the engine is requested in a state in which the engine is rotating during the intermittent stop, and perform a retarded injection control that retards, in a combustion cycle of the engine, a starting time of a first fuel injection at the time of the restart of the engine by the self-sustaining resumption as compared to a starting time of a second fuel injection.

Vehicle controller and vehicle control method

A controller and a control method for an internal combustion engine, and a memory medium are provided. In a first combustion cylinder, first combustion is caused by control circuitry when the engine is restarted from a state where fuel combustion in cylinders is suspended. An automatic stopping process suspends the fuel combustion in the cylinders and controls a throttle valve to a closed state when a predetermined condition is satisfied. A first calculation process calculates an amount of fuel injected into the first combustion cylinder based on a position of the piston in the first combustion cylinder in a case where a rotation speed of a crankshaft obtained when the restart was requested is zero. A second calculation process calculates the injection amount based on the rotation speed in a case where the rotation speed obtained when the restart was requested is higher than zero.
