  • Patent number: 11568688
    Abstract: A system is described that can include a first database, a simulator, and a second database. The first database can store data indicating operation of at least one module within a computing device of an autonomous vehicle. The simulator can receive the stored data from the first database. The simulator can generate, based on the received data, a simulation of the operation of the at least one module. The simulator can identify at least one portion of the simulation that indicates a deviation between the collected data and the simulated operation of the autonomous vehicle. The simulator can analyze the at least one portion of the simulation to generate metrics for the at least one portion of the simulation. The metrics can be used to avoid another deviation between the collected data and the simulated operation of the autonomous vehicle. The second database can store the metrics.

  • Patent number: 11536628
    Abstract: Time required by a crankshaft to rotate 30° CA from a compression top dead center is defined as time T30. A CPU calculates a rotation fluctuation amount ?T30 related to a cylinder subject to determination of a misfire by subtracting a value related to a cylinder in which a compression top dead center occurred immediately before the cylinder subject to the determination from a value related to the subject to the determination. The rotation fluctuation amount ?T30 that corresponds to a cylinder in which a combustion operation is stopped is used as a reference value ?T30ref. When a combustion operation is performed, it is determined that there is a misfire if the absolute value of the difference between the rotation fluctuation amount ?T30 and the reference value ?T30ref is less than or equal to a determination value ?th.

  • Patent number: 11512658
    Abstract: An engine device includes: an engine; and a control device that executes a return rich control that controls the engine so that an air-fuel ratio becomes rich over a predetermined period after the engine returns from the fuel cut. When the engine is intermittently stopped during the execution of the return rich control, the return rich control is executed for a period shorter than the predetermined period after the engine is restarted. Thus, when the engine is intermittently stopped during the execution of the return rich control and the engine is restarted thereafter, it is possible to suppress a total period of the return rich control from becoming long. As a result, it is possible to suppress an increase in the amount of hydrocarbons in the exhaust gas and suppress deterioration of emissions.

  • Patent number: 11495064
    Abstract: The disclosure includes embodiments for providing value-based sensor data suppression in a cooperative perception message transmission by an ego vehicle. A method includes ascertaining, by a processor of the ego vehicle, a mounting height of a first sensor of the ego vehicle. The method includes calculating a value of sensor data recorded by the first sensor based on the mounting height. The method includes determining a satisfaction state of a threshold based on the value. The method includes determining to transmit the cooperative perception message without the sensor data based on the satisfaction date of the threshold so that value-based sensor data suppression is achieved. The sensor data is suppressed because it is not included in a payload of the cooperative perception message. The suppression is value-based because the sensor data is suppressed responsive to the threshold for value not being satisfied.

  • Patent number: 11479236
    Abstract: A control system for a hybrid vehicle configured to suppress a temperature rise in a transmission while achieving a required driving force without modifying a cooling system. If a temperature in the transmission is lower than a threshold level during propulsion in a hybrid mode, a controller operates an engine at an optimally fuel efficient point. If the temperature in the transmission system is equal to or higher than the threshold level during propulsion in a hybrid mode, the controller shifts the operating point of the engine to the point at which the heat generation in the transmission system can be suppressed.
