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.

摘要： An engine system includes an engine, an alternator, a load, and a controller that communicates with the engine, the alternator, and the load. The controller signals the engine to drive the alternator when the engine idles. When a load increase on the engine is detected, the controller reduces an alternator load on the engine in response to the load increase. Air flow into the engine is adjusted to compensate for the load increase, and concurrently the alternator load is increased. When a load decrease is detected, the alternator load is increased, and the air flow is subsequently adjusted while decreasing the alternator load. In another embodiment, spark timing of the engine is adjusted to compensate for the load decrease.

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 regulator voltage control includes measuring a current of a battery, determining a state of charge (SOC) of the battery based on the current, and determining a nominal optimum charging voltage as a function of the SOC of the battery. The nominal optimum charging voltage is converted to a % duty cycle, and a generator is operated relative to the % duty cycle for charging the battery. The nominal optimum charging voltage is reduced when either a battery charge current is below a predetermined value, or a current drawing accessory is turned on.

摘要： In a fuel composition sensor in which a fast step voltage is applied to a capacitive voltage divider comprising a sensor capacitance and a reference capacitance in series, a padding capacitor is connected in parallel with the sensor capacitor to produce a more linear output across the full range of fuel composition. The value of the padding capacitor is sufficient to produce a capacitance ratio of the voltage divider substantially less than one and, in particular, less than two thirds.

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.
