Control Means Selectively Operates Engine Energy Input And Brake Patents (Class 477/27)
  • Patent number: 11152653
    Abstract: A system and method for managing thermal energy of a vehicle having a battery and an electric propulsion system are provided. The system monitors a current battery temperature, calculates an actual average battery temperature, and compares the calculated actual average battery temperature to a target lifetime battery temperature. If the actual average battery temperature is greater than the target lifetime battery temperature, and the current battery temperature is greater than the target lifetime battery temperature, the system cools the battery to below the current battery temperature. However, if the actual average battery temperature is less than the target lifetime battery temperature, and the current battery temperature is greater than the target lifetime battery temperature, the system delays cooling the battery. Therefore, the system may avoid expending energy to cool the battery in certain conditions.

  • Patent number: 10910966
    Abstract: A motor control system is provided. The system includes an inverter that adjusts a stator current applied to a stator coil of a wound-rotor drive motor and a rotor current applied to a rotor coil of the drive motor. When an abnormal starting of the drive motor is detected and a movement of the vehicle is restricted by electronic parking brakes (EPB), a motor controller adjusts the rotor current through the inverter to cancel an abnormal starting torque caused by the abnormal starting.

  • Patent number: 8876658
    Abstract: In an electrically driven vehicle propelled by an electric machine (motor)equipped with a collaborative braking system of regenerative and frictional braking capacities, in order to achieve the “rollback prevention” at starting on an sloping road, when the regenerative braking is not available due to charging restriction to battery, frictional braking is used instead of regenerative braking and wheels are (automatically, i.e. not manually by driver) braked with friction to prevent the rollback. Moreover, in addition to braking wheels by frictional braking, further control is performed to adjust and match the magnitude of frictional braking force to a braking force in accordance with the starting operation. Thus, at the time of rollback prevention by the frictional braking as well, the similar prevention of rollback will be possible as the prevention by way of regenerative braking such that the effect of rollback prevention may be achieved without a feel of discomfort.

  • Patent number: 8831842
    Abstract: A system for simulated shifting for a hybrid vehicle, the system includes a plurality of wheels, an engine, a sensor, a transmission, a memory for storing target engine speeds and deceleration torques for a plurality of simulated gears, and a processor. The engine provides a torque to the plurality of wheels. The sensor detects a requested deceleration torque. The transmission simulates a current simulated gear by delivering an applied torque, which corresponds to the requested deceleration torque, to the plurality of wheels and an engine speed corresponding to the simulated gear. The processor simulates a downshift by increasing an engine speed of the engine without changing the applied torque to the plurality of wheels when the requested deceleration torque exceeds a deceleration torque of a lower simulated gear.

  • Patent number: 8267350
    Abstract: An actuator, comprises a housing, a first prime mover for producing rotary motion, a first gearbox arranged to convert in use the rotary motion from the first prime mover into rotary motion having higher torque and lower speed. The first gearbox comprises a casing mounted for rotation relative to the housing of the actuator and a second gearbox arranged to convert rotary motion of the casing of the first gearbox into rotary motion having lower torque and higher speed. A brake is arranged to act on the rotary motion having lower torque and higher speed from the second gearbox. In use when the first gearbox is not jammed, the brake may be applied to resist relative rotation between the casing of the first gearbox and the housing of the actuator. When the first gearbox is jammed, the brake may be released thereby allowing the casing of the first gearbox to rotate relative to the housing of the actuator. The actuator may thereby be jam-tolerant. A second motor may also be provided.

  • Patent number: 8190317
    Abstract: The present invention provides a mode change control method of a hybrid vehicle, which can improve driving performance and power performance and provide a more stable vehicle behavior control during a mode change from an EV mode to a HEV mode. For this purpose, a transmission input speed is compared with an engine idle speed. If the transmission input speed is lower than the engine idle speed, the pressure of a clutch is open-loop controlled so that an optimal engine torque of operation point determination circuit can be transferred to the clutch. On the other hand, if the transmission input speed is equal to or higher than the engine idle speed, the clutch pressure is feedback-controlled so that a delta RPM follows a target delta RPM profile.

    Abstract: The present invention provides a torque control method for an HEV, the method comprising: detecting an operation failure of an integrated starter-generator (ISG); calculating a driver demand torque based on a current accelerator position sensor (APS); controlling the hydraulic pressure and operation of a clutch so as to increase an engine speed to convert the driving mode of the vehicle from electric vehicle (EV) mode to hybrid electric vehicle (HEV) mode in the event that an operation failure of the ISG is detected and the driver demand torque is out of a predetermined range; and compensating the driver demand torque to a desired level based on a transfer torque from the clutch to a motor. The method can improve driving performance and power performance of HEV, in the event of ISG failure, by performing a hydraulic control for a clutch and calculating a driver request torque and a transfer torque from the clutch to a motor to compensate the drive request torque to a desired level.
