Abstract: 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.

Abstract: A vehicle controller includes processing circuitry configured to execute a counter updating process, first and second starting processes, and a resetting process. The resetting process includes resetting the crank counter when a crank counter has a value outside of a range corresponding to a tooth-missing portion in a case in which a magnitude of a difference obtained by subtracting a value of a pre-update crank counter from the value of the crank counter that was increased by receiving the pulse signal in the counter updating process is greater than a first threshold value corresponding to a specified angle. The resetting process further includes resetting the crank counter when the crank counter has a value within the range corresponding to the tooth-missing portion in a case in which the magnitude of the difference is greater than a second threshold value that is greater than the first threshold value.

Abstract: The electronic control unit performs a retarding process of retarding the ignition timing when the fuel pressure decreases, and lowers the peak of the combustion pressure in the cylinder, thereby suppressing the inflow of the combustion gas to the injector. Further, the electronic control unit performs an increasing process of increasing the injection amount of the hydrogen gas together with the retarding process, thereby suppressing the torque decrease of the engine due to the retard of the ignition timing.

Abstract: An internal combustion engine uses hydrogen as fuel. The internal combustion engine includes a coupling passage that connects a crankcase and a surge tank to each other. A controller executes a control of causing an air-fuel ratio of an air-fuel mixture to be lower when a target output of the internal combustion engine is relatively high than when the target output is relatively low. The controller executes a pressure reduction process of reducing a pressure in an intake passage when the target output is less than a specific value. The pressure reduction process is a process of reducing the pressure in the intake passage to be lower than that before the execution of the pressure reduction process.

The pattern determining section determines a target deactivation interval as a subsequent deactivation interval when the difference between a current deactivation interval and the target deactivation interval is less than or equal to X cylinders, and determines, as the subsequent deactivation interval, an interval closer to the target deactivation interval than the current deactivation interval by X cylinders when the difference between the current deactivation interval and the target deactivation interval exceeds X cylinders. The value of X is a natural number and a variable value that varies in accordance with the operating state of the engine.

The method includes, when setting N to an integer greater than or equal to 1, repeatedly performing a cylinder deactivation in a pattern in which combustion is consecutively performed in N cylinders in the order of cylinders entering a combustion stroke, and then a subsequent cylinder is deactivated. The method further includes changing the combustion cylinder ratio by changing the pattern such that the value of N is changed by one at a time.

Abstract: A port injection valve injects fuel to an intake passage. In multiple injection processing, a demanded injection quantity of the fuel is divided into a synchronous injection quantity and a non-synchronous injection quantity in accordance with at least one of: the load, which is a physical quantity having a correlation with the amount of air to be filled; and the temperature of an internal-combustion engine. The fuel is injected through intake non-synchronous injection and intake synchronous injection in this order. In the intake synchronous injection, the fuel is injected synchronously with a valve-open period of an intake valve. In the intake non-synchronous injection, the fuel is injected at a timing more advanced than in the intake synchronous injection.
