摘要： A control system for an engine throttle valve actuator uses an actuator position feedback loop with a compensation factor which applies a reverse voltage having an amplitude based on actuator momentum to a DC motor to effectuate an electrical braking action to achieve high speed response with positional accuracy. A separate position limiting feedback loop is used to prevent excessive actuator excursions. The engine throttle valve is controlled to a selected position by using a throttle valve position feedback loop and a compensation factor to provide a feedback signal to a summing junction.

摘要： A viscous clutch (10) is typically employed in a fan drive mechanism within a truck or automobile. A shaft (18), driven by the engine (12), rotates a clutch member (42) within the fan drive. The clutch member is arranged for fluid engagement with a body member (60) for the transmission of torque thereto when fluid is disposed in an operating chamber (100) defined by complimentary shear surfaces in the clutch and body members (48,98), respectively. An actuator assembly (30) operates to displace a valving element (196) within the clutch to control the torque transmission therethrough and thus the speed of the output shaft and fan (34) thereof. The actuator is electrically powered by a generator (222) made up of an armature (224) carried by the body member and a plurality of field generating magnets carried by clutch member (42) for rotational interaction therebetween. The clutch is tetherless and receives a slip speed demand signal by an optical or other non-contacting data link to provide tight control of fan speed and engine outlet coolent temperature.

摘要： A viscous fan clutch (10) is typically employed in a fan drive mechanism within a truck or automobile. A shaft (18), driven by the engine (12), rotates a clutch member (42) within the fan drive. The clutch member is arranged for fluid engagement with a body member (60) for the transmission of torque thereto when fluid is disposed in an operating chamber (106) defined by complimentary shear surfaces in the clutch and body members (48 and 98), respectively. A tether assembly (30) operates as an actuator to displace a valving element (196) within the clutch to control the torque transmission there through and thus the speed of the output shaft and fan (34) thereof. Fan speed is regulated by variable current signal applied to a coil (174) within assembly (30) to selectively variably frictionally engage valve element assembly (196) with a grounded thrust surface or reaction member (190) to effect limited displacement of a valve element (198) in response thereto. A fan speed feedback signal is generated by teeth (164) passing in close proximity to a magnetic pick-up (166) is integrated within tether housing (122) and output to control circuit (222) via a conducting path (173 or 183).

摘要： A drivetrain (48) for an electric passenger vehicle (10) includes a battery (40) for energizing a single-phase A.C. traction motor (18) which drives a ground engaging wheel (12) through a multi-speed transaxle (20). The motor is characterized by an external ferrite permanent magnet rotor (26) drivingly engaging an input shaft (32) of the transaxle. The motor is controlled by an inverter circuit (44) and a control circuit (46) which generates switch command signals to reciprocally actuate power transistors (56 and 62) within the inverter circuit as a function of operator demand, rotor position and rotor speed. The control circuit includes a motor positioning circuit (442) which toggles the motor current when the rotor speed falls below a predetermined level to dither the rotor about a park position for a predetermined period. A pre-start rotor positioner (224) is provided to mechanically lock the rotor in its park position to ensure the availability of a high electrical starting torque. Finally, a minimum starting speed circuit (599) provides for motor startup from other than the normal rotor park position.

摘要： An inverter (34) which provides power to an A.C. machine (28) is controlled by a circuit (36) employing PWM control strategy whereby A.C. power is supplied to the machine at a preselectable frequency and preselectable voltage. This is accomplished by the technique of waveform notching in which the shapes of the notches are varied to determine the average energy content of the overall waveform. Through this arrangement, the operational efficiency of the A.C. machine is optimized. The control circuit includes a micro-computer which calculates optimized machine control data signals from various parametric inputs and during steady state load conditions, seeks a best V/HZ ratio to minimize battery current drawn (system losses) from a D.C. power source (32). In the preferred embodiment, the present invention is incorporated within an electric vehicle (10) employing a 144 VDC battery pack and a three-phase induction motor (18).

摘要： A hybrid powertrain system is provided that includes a first prime mover having a rotational output, a second prime mover having a rotational output, and a transmission having a main shaft supporting at least two main shaft gears thereon. The transmission includes a first independent countershaft drivingly connected to the first prime mover and including at least one ratio gear supported thereon that meshes with a respective main shaft gear. A second independent countershaft is drivingly connected to the second prime mover and includes at least one ratio gear supported thereon that meshes with a respective main shaft gear. The ratio gears on the first and second countershafts cooperate with the main shaft gears to provide at least one gear ratio between the first and second countershafts and the main shaft. A shift control mechanism selectively engages and disengages the first and second countershafts for rotation with the main shaft.
