  • Publication number: 20250109720
    Abstract: A controller and a control method for an internal combustion engine are provided. The internal combustion engine uses hydrogen as fuel. A base value of a fuel injection amount is calculated based on a requested torque. A smaller one of an upper limit value of the fuel injection amount and the base value is set as a target value. The upper limit value corresponds to an engine load factor. A NOx concentration difference is a difference between a NOx concentration in exhaust gas and a reference value for the NOx concentration. When the NOx concentration difference is greater than or equal to a threshold value, a relationship between the engine load factor and the upper limit value is corrected such that the upper limit value decreases.

  • Patent number: 12122353
    Abstract: A control device starts supply of electric power to a catalyst device when a state of charge of a main battery decreases to a value which is equal to or less than an optimal power-supply state of charge set based on a travel load while a vehicle is traveling in an EV travel mode. The control device corrects input electric power of the catalyst device to a value less than the value at the time of starting of supply of electric power when the travel load decreases after the supply of electric power has been started.

  • Patent number: 11795884
    Abstract: A control device is applied to an internal combustion engine equipped with an electric heating catalyst system provided with an EHC. The control device executes a preheating process to warm up an exhaust gas reduction catalyst prior to a start of the internal combustion engine by supplying electric power to the EHC, when the control device determines that a temperature of the exhaust gas reduction catalyst is lower than an activation temperature. The control device executes a determination process for determining whether water is adhered to a catalyst carrier. The control device starts the internal combustion engine without executing the preheating process when the control device determines by the determination process that water is adhered to the catalyst carrier, even when the control device determines that the temperature of the exhaust gas reduction catalyst is lower than the activation temperature.

  • Patent number: 11492941
    Abstract: A controller is applied to an internal combustion engine in which an electrically heated catalyst that is heated when supplied with electric power is installed in an exhaust passage. The controller is configured to perform a preheating process of warming up a first exhaust catalyst by supplying electric power to the electrically heated catalyst through control over a power supply before a start of the internal combustion engine. The controller is configured to, when an insulation resistance of the electrically heated catalyst at a start of the preheating process is lower than a threshold, perform the preheating process while decreasing a voltage supplied to the electrically heated catalyst.

  • Patent number: 11148635
    Abstract: An inclination controlling mechanism of a seatbelt device is provided with: a pulley that converts an advancing/retracting movement of a cable of the cable advancing/retracting mechanism; a drive gear mounted around a pivot shaft of the pulley and synchronized with rotation of the pulley; and a driven gear mounted around a pivot shaft of a sensor housing so as to move in conjunction with a rotation of the sensor housing. The drive gear and driven gear engage with each other in a condition where a rotational track surface of the drive gear and rotational track surface of the driven gear intersect at a predetermined angle. As a result, an inertial body supporting surface serving as a sensor reference plane can be accurately maintained horizontally even at an arbitrary seatback recline angle, and thus the accuracy of the acceleration sensor can be improved.
