  • Patent number: 10801497
    Abstract: A controller that controls an electric compressor, which is mounted to a vehicle and configures a two-stage compression refrigeration cycle device, has a deceleration section, an operation stop section, and a restart section. The deceleration section reduces a rotational speed of an electric motor by controlling an AC current which is output to the electric motor, when a two-stage compression mode, in which an intermediate-pressure refrigerant flows into the electric compressor from an intermediate-pressure port, is performed and an operation stop request to stop the electric compressor is made. The operation stop section stops the electric motor after the deceleration section reduces the rotational speed of the electric motor. The restart section restarts the electric compressor when the operation stop request is canceled after the operation stop section stops the electric compressor.

  • Patent number: 10030656
    Abstract: A variable displacement vane pump has a pressure controlled valve moveable between first and at least second valve positions based on an output pressure of the pressurized lubricant delivered through the outlet. The pressure controlled valve provides an integrated fail safe function to the pump when an electrical valve fails. The pressure controlled valve is inactive in the first position for an output pressure below a threshold level, allowing an electrical valve (current, solenoid, pulse width modulation (PWM) valve) to selectively control pressure in the control chamber under normal operation of the pump. In fail safe regulation mode, the electrical valve function is disabled and the pressure controlled valve is active in its second position, controlling pressure in the control chamber. Channels and vents in the pump can be opened and closed based on selective movement of the valve when the outlet pressure is at or above a threshold level.

  • Patent number: 8622711
    Abstract: A fan control circuit of a computer includes a fan interface connected to a connector of a fan, a fan controller, a NOT gate, and an electronic switch. The fan controller outputs a PWM signal to the fan interface to control the operation of the fan, and includes a GPIO interface to output a voltage control signal to the NOT gate to switch the electronic switch on or off. A signal output of the electronic switch is connected to the fan interface. The voltage control signal is high level at the start up moment of the computer, and thus does not turn on the fan via the electronic switch. After a preset delay period, the voltage control signal is turned low by the fan controller so that the fan interface receives the PWM signal.

  • Publication number: 20130280095
    Abstract: Systems and methods of the invention may overcome a higher than normal starting torque for in a reciprocating, electric motor driven air compressor for a vehicle. A detection component can be configured to detect a stall condition for a reciprocating compressor based on a force from compressed air being compressed into a reservoir of the reciprocating compressor. Based upon the detected stall condition, a controller can reverse direction or increase torque to alleviate the stall condition. In the reverse direction mode, the controller component can change a direction of a piston rotation. In the torque increase mode, the controller increases a number of poles for the motor, a line voltage, or a volt/hertz.

    Abstract: A system and method for a compressor includes a compressor connected to a condenser, a discharge line temperature sensor that outputs a discharge line temperature signal corresponding to a discharge line temperature of refrigerant leaving the compressor, and a control module connected to the discharge line temperature sensor. The control module determines a saturated condenser temperature, calculates a discharge superheat temperature based on the saturated condenser temperature and the discharge line temperature, and monitors a flood back condition of the compressor by comparing the discharge superheat temperature with a predetermined threshold. The control module increases a speed of the compressor or decreases an opening of an expansion valve associated with the compressor when the discharge superheat temperature is less than or equal to the predetermined threshold.

  • Patent number: 8483898
    Abstract: A vehicle includes a clutch set, a tank with fluid, an auxiliary battery, an electric fuel pump, and a controller. The electric fluid pump delivers some of the fluid from the tank to a designated oncoming clutch of the clutch set. The controller calculates a predicted flow value for the oncoming clutch during the shift event, and selectively controls the speed of the pump using the predicted flow value during the shift event. The controller controls the pump using an actual flow value when the vehicle is not executing a shift event, i.e., when holding torque. The speed of the electric fluid pump is increased to a first calculated speed determined using the predicted flow value when the shift event is initiated and before filling of the oncoming clutch commences, and is reduced to a second calculated speed determined using the actual flow value when the shift event is complete.
