摘要： Systems, methods and devices are described for controlling a vehicle electrical generator. A regulator for controlling a generator in response to an input signal received from a control module suitably includes a discriminator module, a processing module and a switching circuit. The discriminator determines whether the regulator is operating in voltage or torque control mode. If the input signal is a voltage control, the output generator produces a modulation signal to produce a desired voltage between two battery terminals. If the input signal is a torque control, the output generator produces one or more modulation signals (e.g. pulse width modulation signals) to control the torque of the generator. The modulation signals are applied across a field coil or other controllable element of the generator by a switching circuit that applies positive and/or negative voltage from the battery terminals as appropriate.

摘要： An engine control system for use in connection with vehicles and the like allows the engine speed to be modified using the torque load from the electrical generator. The engine is subject to a torque load from a generator coupled to the engine. The controller compares the desired speed to the actual speed of the engine to determine an error value, and the torque load of the generator is modified (increased/decreased) based on the error value such that the absolute value of the error value is reduced. The generator control is combined with and arbitrated with respect to traditional spark control methods, thus reducing the need for spark timing that is substantially retarded from the mean best timing (MBT) setting. The electrical generator can operate in either voltage control mode or field duty cycle control mode, depending upon various conditions.

摘要： A circuit that detects if contacts in an HV contactor have been welded or stuck closed. The circuit includes a controller that generates a short duration pulse signal that closes a driver switch and allows current flow through a coil in the HV contactor. The current flow is converted to a voltage by a sensor, where the voltage is received by the controller. The controller uses the voltage, such as by comparing the voltage to a stored representative voltage of the coil current for when the HV contactor is open, to determine whether the HV contactor is closed, and possibly welded or stuck closed, or partially closed. The sensor can be the driver switch or another device, such as a resistor.

摘要： A system and method for managing faults occurring in a power steering system in a vehicle is disclosed that has particular application for an MRHPS system to provide reliable functioning of the power steering system. The method includes detecting a fault condition in the MRHPS system and selecting a safe mode from a plurality of predetermined safe modes based on the fault condition. The plurality of predetermined safe modes include a normal operation mode, an engine speed follow mode, a manual mode, a fixed duty cycle mode and a voltage control mode. If a fault condition is detected, the method applies the safe mode to manage the fault condition.

摘要： A method of controlling a magneto-rheological power steering coupling is provided. The method is to be employed by a controller and is initiated upon engine start-up. The method includes initializing calibration parameters and reading a plurality of input values. Subsequently, a hand wheel angle rate value is calculated from one of said plurality of input values. A pump speed command value is calculated as a function of at least the hand wheel angle rate value. A pump speed error value is then calculated, and a proportional-integral-derivative calculation is performed acting on the pump speed error value to determine a pulse width modulation duty cycle value. The duty cycle value is then output to a power driver to provide a control signal to the magneto-rheological power steering coupling. Also provided is control system and apparatus operable to perform the functions described hereinabove.

摘要： A linear actuator associated with an actuator system for a device includes a wire cable fabricated from an active material. The linear actuator couples to the device and to the moveable element. The active material induces strain in the linear actuator in response to an activation signal. The linear actuator translates the moveable element relative to the device in response to the induced strain. An activation controller electrically connects to the linear actuator and generates the activation signal. A position feedback sensor monitors a position of the moveable element.

摘要： Cathode-anode voltage across free-wheeling diodes in an active rectifier is used in the determination of switching points when the free-wheeling diode is forward biased. Hysteretic switching is accomplished through the selection of conductive and non-conductive switching threshold. The switching thresholds are further selected to prevent voltage oscillations at zero current crossings and reduce delays during deactivation to prevent cross-conduction.
