  • Patent number: 11433871
    Abstract: An ECU is configured to control an SOC control center of a battery and perform an engine torque suppression control. The engine torque suppression control is a control that suppresses output of an engine during a predetermined period of time after starting a system, and causes motor generators to output torque supplementing the suppressed output of the engine. When a deposition amount of PM on a filter exceeds a first specified amount, the ECU raises the SOC control center by controlling the motor generators before stopping the system as compared to when the deposition amount of PM is lower than a specified amount, and performs the engine torque suppression control at a next start after stopping the system.

  • Patent number: 11391331
    Abstract: A controller executes a method to manage an engine connect/disconnect decision in a powertrain having an engine, transmission, electric machine, and a battery pack and power inverter module (“TPIM”). In response to vehicle ground speed being less than a calibrated maximum electric vehicle accelerator pedal signal (“EVAPS”) level, the controller calculates a delta APS (“?APS”) value by subtracting a scaled APS value from the actual APS level. The scaled APS value is a scaled variant of a maximum EVAPS value selected from a maximum EVSAPS table, the latter populated based on inverter temperature, state of charge of the battery pack, and ground speed. When the ?APS value exceeds a threshold, the controller connects the engine to the transmission via an engine disconnect clutch. The engine is disconnected based on acceleration of the vehicle and the above-noted factors.

  • Patent number: 10486688
    Abstract: When a temperature of a catalyst in an exhaust emission control device mounted in an exhaust system of an engine is equal to or higher than a predetermined temperature at a time of a request for stopping the engine, a hybrid vehicle including the engine and a motor continues fuel injection of the engine until satisfaction of a predetermined condition and stops fuel injection of the engine on satisfaction of the predetermined condition. When the temperature of the catalyst is lower than the predetermined temperature at the time of the request for stopping the engine, on the other hand, the hybrid vehicle immediately stops fuel injection of the engine.

  • Patent number: 10449965
    Abstract: A driver assistance device for a motor vehicle with a drive assembly, which can be connected to a drivetrain via a clutch that can be activated by an actuator. The clutch being a component of an electronically controlled clutch system, in which a clutch pedal sensor detects an actuation of a clutch pedal on the driver's side and in which an analysis unit determines, in a first control mode on the basis of the detected clutch pedal actuation, a clutch torque and actuates the clutch with a corresponding clutch signal. For an adjustment of the clutch response on the driver's side, the analysis unit is associated with an input unit, for the actuation of which, on the driver's side, it is possible to shift between the first control mode and at least one second control mode.

  • Patent number: 10407049
    Abstract: The disclosure relates to a process for route-dependent control of an energy storage device of an at least partially electrically operated motor vehicle, for example a mild-hybrid passenger vehicle, which is implemented by a charge state control device. In this process, said device receives at least one information-containing data value, which relates to a driving situation to be expected on a route section of a driving route. A prediction of the energy requirement of a first device of an onboard network on the route section takes place using the information received. When a predetermined lower threshold value of the predicted energy requirement of the first device is not met, a control signal is generated that causes an energy quantity of an energy reserve of the energy storage device reserved for the first device of the onboard network to be allocated at least partially to a second device of the onboard network.

  • Patent number: 10364770
    Abstract: The vehicle is a hybrid vehicle capable of traveling using motive power of at least one of an engine and a motor generator. The vehicle includes: a fuel pump; an injection valve injecting fuel supplied from the fuel pump to the engine; a fuel pressure sensor detecting a supply pressure of the fuel generated by the fuel pump; and an engine ECU. The engine ECU performs a fuel pressure increasing process of increasing the supply pressure of the fuel generated by the fuel pump, and conducts a fault diagnosis of the fuel pressure sensor based on a value detected by the fuel pressure sensor during the fuel pressure increasing process. The engine ECU conducts the fault diagnosis of the fuel pressure sensor in a case where the engine is being stopped and a vehicle speed is higher than a threshold value.
