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 method is provided for determining a battery's state-of-health. An initial battery voltage is measured after a first voltage drop during an initiation of an engine cranking phase. A battery voltage is monitored during the remainder of the engine cranking phase. A lowest battery voltage is determined during the remainder of the engine cranking phase. A determination is made if a voltage difference between the lowest battery voltage and the initial battery voltage at the initiation of the engine cranking phase is less than a voltage threshold. A low battery state-of-health is identified in response to the voltage difference being less than the voltage threshold.
