  • Patent number: 11933238
    Abstract: 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.

  • Publication number: 20190164359
    Abstract: A diagnostic apparatus is configured to relay diagnostic communication between a maintenance terminal and a vehicle. The maintenance terminal is used to perform maintenance-management of the vehicle. The diagnostic apparatus includes a control processor configured to: read out, from the vehicle, identification information unique to the vehicle connected to the diagnostic apparatus before wireless connection between the maintenance terminal and the diagnostic apparatus is set up; and transmit the identification information unique to the vehicle to the maintenance terminal. The identification information serves as information for identifying the diagnostic apparatus to which the maintenance terminal is wirelessly connected when the wireless connection between the maintenance terminal and the diagnostic apparatus is set up.

  • Patent number: 8368350
    Abstract: A vehicle-side connector included at one end of a cable through which a power source outside a vehicle feeds a power storage device, includes a signal pin, a resistive element R2 connected to the signal pin at one end, a switch connected in series to the resistive element R2 at one end and grounded at the other end, and a resistive element R3 connected in parallel to the switch. The switch changes from an ON state to an OFF state upon depression of a depression portion located on the vehicle-side connector. The vehicle includes a resistive element R4 whose one end is connectable to the signal pin and other end is grounded and a control device which determines a state of connection of the cable on the basis of a signal voltage value input from a signal line electrically connected to the signal pin.

  • Patent number: 7566289
    Abstract: A shift control ECU includes the steps of storing a position of a shift lever; starting a count-up timer when the shift lever comes to a neutral position; and recognizing a driver's request for the neutral position when a count-up timer value attains TN(1) if the stored shift lever position is a home position and when a count-up timer value attains TN(2) if the stored shift lever position is not the home position. Here, TN(1) is set to be smaller than TN(2).
