    Abstract: A drive system and a method of driving a vehicle, wherein the drive system includes a combustion engine, a motor control function, a gear box, an electric machine, an energy storage and a planetary gear. A control unit receives information concerning the charge level of the energy storage and determines if the charge level is lower than a limit level such that the energy storage needs charging. If this is the case, the motor control function is controlled such that the combustion engine increases rotation speed in relation to the rotation speed when the energy storage does not need charging.

  • Patent number: 9043065
    Abstract: A vehicle is supplied by a first electrical energy storage unit on board the vehicle, and a ground electrical network providing an energy supply by application of a supply voltage through electrical distribution. The first energy storage unit is controllable under a generator regime or a receiver regime. The supply voltage is adjusted, in the generator regime, by applying an algebraically additive supply voltage originating from the first electrical storage unit to the distribution, to maintain a supply voltage above a minimum threshold. In the receiver regime, if a surplus of supply voltage originating at least partially from a second storage unit in the generator regime is detected above the minimum threshold, this surplus is channeled energetically to the first energy storage unit of the vehicle if it is required for operating the vehicle and enables maintaining the supply voltage below a maximum threshold and above the minimum threshold.

  • Publication number: 20150120108
    Abstract: Methods and systems are provided for improving air intake system hydrocarbon trap purging during engine-off time in a hybrid electric vehicle. One method includes opening the throttle during vehicle motion under battery operation and allowing airflow through the trap to purge its contents into the fuel canister via the canister purge valve. Upon transition into the engine-on mode, fuel vapors are released from the canister into the engine intake.

  • Publication number: 20150120115
    Abstract: An electronic control unit executes throttle torque reduction control for decreasing an engine torque by reducing a throttle opening degree during an upshift of an automatic transmission with respect to the throttle opening degree before a start of the upshift. During the upshift of the automatic transmission, the electronic control unit actuates a waste gate valve in a closing direction with respect to a position of the waste gate valve before the start of the upshift in parallel with execution of the throttle torque reduction control. Thus, a decrease in supercharging pressure due to execution of the throttle torque reduction control is suppressed during the upshift, and the engine torque that has been temporarily decreased in an inertia phase of the upshift recovers immediately after the upshift, so it is possible to suppress deterioration of drivability.

  • Publication number: 20150120122
    Abstract: A hybrid vehicle having a power-transferable combination of an engine and a motor-generator is controlled to prevent a vehicle vibration while preventing an over-revolution of the engine when the engine is started. In such control, while the engine is determined to be in a starting state, an instruction value correction is performed for correcting a per-unit-time change amount of an actuator instruction value, such as a target air intake amount and/or a target air load amount, according to a target output of the engine so that a steep increase of the engine revolution speed is prevented. With such a correction of the instruction value, an air intake amount of the engine and the engine revolution speed is gradually increased, thereby preventing the over-revolution of the engine and a steep increase of a load torque of the motor-generator, which prevents vehicle vibration when the engine is started.

  • Publication number: 20150120104
    Abstract: A system and a method for a hybrid vehicle for pre-charging the battery. A hybrid vehicle includes a battery having a state of charge (SOC), an engine configured to charge the battery, an actuation device having an on state and an off state, and a processor configured to activate the engine to charge the battery when the actuation device is switched to the on state until the SOC reaches a required SOC. The required SOC may be input by a driver and may exceed a normal maximum SOC utilized by the hybrid vehicle. The pre-charge feature can override the normal hybrid vehicle battery management logic. The required SOC allows the driver to perform reverse maneuvers without running out of battery power.

  • Patent number: 9020676
    Abstract: A method and a system that control a drive torque of a vehicle in which there is a change in a torque of a predetermined magnitude when drive power of the vehicle enters a zone in which a predetermined maximum output is generated to allow a driver to feel that the drive power of the vehicle enters the maximum output zone during traveling. The method may include calculating, by a controller, a drive request torque of a vehicle and calculating drive power displayed on a drive power gauge of an instrument cluster based on the calculated drive request torque. In addition, the method may include adding, by the controller, a predetermined additional torque to the drive request torque when the calculated drive power displayed on the drive power gauge enters a predetermined zone of the drive power gauge.

  • Patent number: 9020673
    Abstract: A hybrid vehicle includes an internal combustion engine (22), a motor (MG2), and a secondary battery (50), and travels in an electric-powered travel mode and in a hybrid travel mode. In the hybrid vehicle, an execution travel mode is set to one of two travel modes including an electric-powered travel priority mode where the hybrid vehicle travels with priority being given to the electric-powered travel mode over the hybrid travel mode, and a hybrid travel priority mode where the hybrid vehicle travels with priority being given to the hybrid travel mode over the electric-powered travel mode. When the execution travel mode is switched while the internal combustion engine (22) is being operated, the internal combustion engine (22) and the motor (MG2) are controlled so that charging/discharging electric power for charging or discharging the secondary battery (50) is gradually changed and the hybrid vehicle travels in the switched execution travel mode (S750 to S800).

  • Publication number: 20150112522
    Abstract: A vehicle includes an engine, an electric machine, a battery, and at least one controller. The vehicle may further comprise a port for supplying power to a load external to the vehicle. The controller is programmed to operate the engine at a power level based on a difference between a battery voltage and a reference voltage such that a power output by the electric machine reduces the difference. The power level may define an engine operating point that minimizes fuel consumption. The operating point may be an engine torque and an engine speed. The power level may be further based on a state of charge of the battery. The electric machine may be operated to cause the engine to rotate at an engine speed corresponding to the selected power level. The difference may be caused by varying power drawn by a load external to the vehicle.
