  • Patent number: 11499466
    Abstract: A method is for route identification that is conducive for successful diagnosis of an exhaust gas treatment system of a vehicle. In the method, an ECU in the vehicle receives a value of GPS coordinates from a GPS module, and the ECU retrieves a value of day, date, and time from an ECU clock. The ECU monitors a value of engine operating conditions with reference to the received value of GPS coordinates and the retrieved value of day, date, and time. The ECU identifies a segment of GPS coordinates for successful diagnosis of an exhaust gas treatment system based on the monitored value. Upon the identification, the segment of GPS coordinates is stored in ECU memory.

  • Patent number: 11486343
    Abstract: In an electromagnetic fuel injection valve, a plurality of recess parts are provided in an attracted face of a movable core, the recess parts dividing a taper face of the movable core into a plurality of sections along a peripheral direction of the movable core. Accordingly, a fuel oil film present in an engaged part between an annular projection of a fixed core and the taper face is sectioned at a plurality of locations, thereby suppressing a sticking phenomenon of the engaged part caused by the fuel oil film. Therefore, when energization of a coil is cut off, a delay in detachment of the movable core from the fixed core is eliminated, thus contributing to improvement of valve-closing responsiveness.

  • Patent number: 11473546
    Abstract: A starter assembly which includes a switch for energizing a solenoid. Energizing the solenoid biases a starter gear into engagement and energizes the starter motor. A thermally responsive switch is positioned to absorb heat generated by operation of the electric motor and is disposed in an electrical line controlling operation of the switch controlling the solenoid wherein opening of the thermally responsive switch results in the opening of the solenoid switch. The use of such a thermally responsive switch de-energizes the electric motor when the electric motor is subjected to elevated operating temperatures that might otherwise cause damage to the electric motor. The starter assembly may also include control circuitry that includes a microprocessor wherein the control circuitry is operably coupled with the switch controlling the solenoid. The control circuitry is programmed to de-energize the solenoid upon the satisfaction of predetermined conditions to thereby prevent damage to the electrical motor.

  • Patent number: 11465607
    Abstract: A vehicle includes an engine, a second MG for running, a battery that supplies and receives electric power to and from the second MG, and an ECU. The ECU is configured to control the engine and the second MG and to execute intake air amount learning. When the SOC of the battery exceeds a second threshold value that is higher than a first threshold value while the vehicle is running using the second MG with the engine in a stopped state, the ECU maintains the engine in the stopped state and maintains the second MG in a driven state, and then does not execute the intake air amount learning. When the SOC of the battery takes a value between the first threshold value and the second threshold value, the ECU starts the engine, drives the second MG with constant torque, and executes the intake air amount learning.

  • Patent number: 11428185
    Abstract: A control device for an internal combustion engine includes an information acquirer, a first computing unit, and a second computing unit. The information acquirer acquires information on a state amount that changes depending on the operation state of the internal combustion engine. A region determiner determines whether the state amount falls within a set region. The first computing unit uses an in-region state amount within the set region, as an input value to compute a control amount of the internal combustion engine by a neural network. The second computing unit selects a reference state amount within the set region, based on the out-of-region state amount, uses the selected reference state amount as an input value to compute a reference control amount by the neural network, and computes the control amount corresponding to the out-of-region state amount based on the computed reference control amount.
