  • Patent number: 11458950
    Abstract: A drive force control system configured to reduce a total energy consumption of a hybrid vehicle. The drive force control system calculates: an output power of the engine which can optimize a thermal efficiency given that the engine is operated at a best fuel point; and a required electric power to be supplied from a battery or to be generated by a control motor, which can adjust the drive power established by the output power of the engine to the required power. A power exchange between the control motor and the battery is interrupted if the required electric power to be supplied from the electric storage device or to be generated by the control motor is less than a first predetermined electric power.

  • Patent number: 11267454
    Abstract: A control system for a hybrid vehicle that can prevent an overcharging of a battery even if a wheel speed drops abruptly. The hybrid vehicle comprises: an engine; a generator that is driven by the engine; a drive motor that generate a drive torque; and a battery. The electric power generated by the generator is supplied directly to the battery or the drive motor. A controller is configured to determine whether the drive wheel will be locked, and to reduce the electric power generated by the generator less than an acceptable input power to the battery if the drive wheel is expected to be locked.

    Abstract: A control system of a hybrid vehicle includes an internal combustion engine loaded on a vehicle, an electric motor loaded on the vehicle, and connected to wheels via a power transmission mechanism, a battery storing power that drives the electric motor, and a control device that controls engine torque generated by the internal combustion engine, and motor torque transmitted to the wheels by the electric motor. The control device calculates an outputable power of the battery based on a temperature and a state of charge of the battery. The control device is configured to make a torque change amount of the engine torque larger when the calculated outputable power belongs to a predetermined low power region than when the outputable power belongs to a high power region with higher power than the low power region.

  • Patent number: 10954876
    Abstract: A vehicle system includes: an internal combustion engine including an electronically-controlled throttle valve configured to change throttle opening degrees in a step-wise manner among at least three selectable opening degrees, and being mounted on a vehicle; and a control device configured to control the vehicle. The control device includes a required throttle opening degree setting component and a first throttle opening degree selecting component. The first throttle opening degree selecting component is configured to: select, at the time of acceleration of the vehicle, a first throttle opening degree that is greater than the required throttle opening degree and is the closest to the required throttle opening degree; and select, at the time of deceleration of the vehicle, a second throttle opening degree that is smaller than the required throttle opening degree and is the closest to the required throttle opening degree.

  • Patent number: 10940644
    Abstract: In a state in which an insert (310) is embedded in an embedding opening of a panel (300) and a nozzle (211) of a dispenser (210) is located above an injection hole of the insert, an air cylinder (230) presses an edge of a discharge port (212) of the nozzle on an edge of the injection hole of the insert. Subsequently, the dispenser discharges an adhesive from the discharge port of the nozzle. The adhesive is injected from the injection hole of the insert, and fills a gap between the insert and the panel. Therefore, the insert is fixed to the panel.

  • Patent number: 10718276
    Abstract: A failure diagnosis apparatus according to the present disclosure is applied to a variable compression ratio mechanism that can switch the compression ratio of an internal combustion engine between at least a first compression ratio and a second compression ratio lower than the first compression ratio. When the variable compression ratio mechanism is controlled so as to set the compression ratio of the internal combustion engine to the second compression ratio, the failure diagnosis apparatus advances the ignition timing of one cylinder to a knock inducing ignition timing more advanced than the MBT that does not lead to the occurrence of knock if the actual compression ratio of that cylinder is the second compression ratio but leads to the occurrence of knock if the actual compression ratio of that cylinder is the first compression ratio and diagnoses failure of the variable compression ratio mechanism on the basis of whether knock occurs or not.
