  • Patent number: 11407316
    Abstract: A vehicle travel control device includes: a control section controlling operation of a motor generator and a power storage device. The control section performs SOC reduction control based on determination that while the own vehicle is traveling on a travel scheduled route, a section is present in which a predetermined amount of regenerative power generation by the motor generator in the own vehicle exceeds an SOC upper limit value. The SOC reduction control reduces a current SOC of the power storage device by setting an SOC lower limit value as a lower limit, to recover all electric power generated by the regenerative power generation. The control section performs efficiency priority travel based on determination that the predetermined amount of regenerative power generation is not actually expected to be available. The efficiency priority travel places priority on vehicle fuel economy or electric power efficiency.

    Abstract: An update process updates relationship defining data by inputting, to a predetermined update map, a state of a vehicle obtained by a state obtaining process, a value of an action variable used to operate an electronic device, and a reward corresponding to an operation of an electronic device. A range in which an operation process uses, as the action variable, a value different from a value that maximizes an expected return related to the reward is defined as a return non-maximizing range. In a case in which a degree of deterioration of the vehicle is greater than or equal to a predetermined degree, a changing process changes the return non-maximizing range to a side on which the return non-maximizing range is expanded as compared to a case in which the degree of deterioration is less than the predetermined degree.

  • Patent number: 11035301
    Abstract: A method for preventing an engine air flow calculation error applied to an engine system may classify an engine operation area of an engine into a sensor measurement deviation generation area, medium/high load areas, and a low load area by an ECU, and classify an air flow calculation applied to a cylinder charging amount of the engine as one of an air flow calculation control applying a compensation measurement air flow to the sensor measurement deviation generation area, an air flow calculation control applying a measurement pressure to the medium/high load areas, and an air flow calculation control applying a measurement air flow to the low load area, excluding influence of an HFM sensor error causing a change in a fresh air charge and inaccuracy of an exhaust gas recirculation (EGR) air flow modeling/active purge air flow modeling in the entire operation area of the engine.

  • Patent number: 11008930
    Abstract: When an incremental amount of a steering angle exceeds a reference incremental amount, an ECU 60 executes vehicle attitude control of reducing an output torque of an engine, and, in a given operating range, drives a spark plug 16 to allow an air-fuel mixture to be self-ignited at a given timing, thereby executing SPCCI combustion. When there is a request for an additional deceleration from the vehicle attitude control (#12: YES) and the SPCCI combustion is performed (#13: YES), the ECU 60 prohibits ignition retardation and performs torque reduction for the vehicle attitude control, by fuel amount reduction control of reducing the amount of fuel to be supplied into a cylinder 2 (#14). On the other hand, when the SPCCI combustion is not performed (NO in #13), the ECU 60 performs the ignition retardation to attain the torque reduction for the vehicle attitude control (#15).

  • Patent number: 10995725
    Abstract: A control device for the selective control of a multiplicity of actuators of an internal combustion engine is provided. The control device includes a central control unit, and a multiplicity of actuators associated with the multiplicity of actuator controls, which are connected to the central control unit. Each actuator control, of the multiplicity of actuator controls, includes an address, so that the actuator controls are selectively controllable by the central control unit by means of the address. Also, each actuator control includes a comparator, which is configured to compare a signal, preferably a voltage or current signal, emitted by the central control unit with the address. The comparator also emits an activation signal via an activation line, if the comparison has resulted in a match of the signal with the address of the respective actuator control within a window, preferably a voltage window (?V).

  • Patent number: 10982607
    Abstract: Methods and systems are provided for diagnosing a vehicle fuel system for a presence or absence of undesired evaporative emissions. In one example, a method comprises evacuating the fuel system of a vehicle to a variable vacuum target as a function of a volatility of fuel in a fuel tank positioned in the fuel system and a loading state of a fuel vapor storage canister configured for capturing and storing fuel vapors from the fuel tank. In this way, analysis of a pressure-bleedup portion of the diagnostic may be more reliable and completion rates of the diagnostic may be improved, while conducting the test in an environmentally fashion.

  • Patent number: 10975796
    Abstract: A fuel injection apparatus for injecting fuel to an engine having cylinders, includes: injectors corresponding to the cylinders; a regulator for fuel pressure supplied to the injectors; and a processor. The processor performs: deciding to start a deposit removal for removing deposits adhering to injector-nozzles; and controlling each injector to inject fuel in a single injection mode for injecting one time or a divided injection mode for injecting multiple times in one combustion cycle and control the regulator based on engine operation condition. The controlling includes, when controlling each injector to inject fuel in the divided injection mode based on the engine operation condition, sequentially controlling each injector to reduce injection number in one combustion cycle when the deposit removal is decided to be started, and then controlling the regulator to increase fuel pressure.

  • Patent number: 10977583
    Abstract: In some implementations, a system is capable of generating and distributing access credentials to users that access a rental property for a limited time period. Users can be provided with access to the rental property through an application or webpage portal without creating a new user account or user login for the application. For example, a user can be granted access to control electronic devices associated with a monitoring system of a rental property without creating a new user account with the monitoring system. Techniques described herein enable such users to more easily access, for example, rental property information that is associated with a monitoring system of the rental property. In this manner, access credentials can be distributed to users through any suitable means, e.g., through email or SMS, and used to temporarily authenticate users.

  • Patent number: 10947914
    Abstract: Methods and apparatuses for calibration and control of various engine subsystems using a target value approach. Under the target value approach, the control of each engine subsystem is separated or decoupled to include a set of target values, or a reference value set. A subsystem has a corresponding target determiner, which provides a target value set, or reference value set, in response to a basis variable set and optionally an overall subsystem target. The basis variable set includes parameters selected to robustly characterize the variables that affect the operation of the particular subsystem. The target determiner is optionally calibrated to provide a reference value set within specifications of the subsystem. A physical subsystem controller operates in response to the reference value set.

  • Patent number: 10934965
    Abstract: A method of controlling combustion in an internal combustion engine includes measuring parameters of combustion in a cylinder of the engine during a combustion phase of the cylinder, after igniting an air/fuel charge in the cylinder, and calculating the heat release of combustion in the cylinder based on the measured parameters. An auto-ignition event of the air/fuel charge is identified based on the calculated heat release, and, based at least in part on the identified auto-ignition event, at least one of ignition timing in the cylinder for the next combustion phase of the cylinder or an amount of exhaust gas supplied to the cylinder for the next combustion phase of the cylinder is controlled to cause an auto-ignition event of the air/fuel charge in the next combustion phase to shift toward a specified crank angle.
