摘要： A circuit and method are provided for heating a dual heater oxygen sensor. One resistance element is of relatively low resistance such that the oxygen sensor is heated quickly and the other element is of relatively high resistance such that the oxygen sensor is heated and maintained at an optimal operating temperature. The circuit and associated method turn on a low resistance start heater that is in communication with the oxygen sensor given start-up conditions. Once the oxygen sensor has reached an operating temperature range a high resistance operating temperature heater is turned on and the start heater is turned off.

摘要： A method for pulse width modulating a resistance element of an oxygen sensor. The method quickly heats the resistance element of the oxygen sensor soon after start of the engine with a relatively high duty cycle yielding wide pulse widths. During a mid oxygen sensor temperature range, the method decreasing the duty cycle and thereby the pulse width modulation. And, upon the oxygen sensor reaching peak operating temperature range, the method decreases the pulse width modulated voltage signal supplied to the oxygen sensor to relatively short duty cycled pulses.

摘要： A multi-function apparatus and a method for performing the functions of a starter, alternator and engine stabilization system for an engine of a motor vehicle. The apparatus comprises a rotor, a stator and a switching/detection system associated with the stator. The stator comprises three independent stator sectors which each comprise a plurality of independent stator coils. The rotor comprises a plurality of rotor poles about its periphery. The rotor is secured to the flex plate of the engine and the stator sectors are secured to the bell housing of the vehicle's power train. The stator coils each protrude through opening formed in the bell housing such that the rotor poles are closely adjacent the stator coils without contacting the stator coils as the rotor rotates. The switching/detection system is used to detect the positions of the rotor poles relative to the stator coils and selectively energizes various groups of stator coils for very brief, predetermined time intervals to cause movement of the rotor and therefore assist in starting of the engine. In the alternator mode energy generated in the stator coils is returned to the vehicle's battery. In the engine stabilization mode selected groups of stator coils are periodically energized to assist in smoothing out the idle of the engine of the vehicle at low idle speeds. The apparatus and method can also be used to propel the vehicle for distances determined by the energy stored in the vehicle battery, to act as a supplemental "power booster" and as a brake for effecting powertrain braking.
摘要翻译：一种用于执行机动车辆的发动机的起动器，交流发电机和发动机稳定系统的功能的多功能装置和方法。该装置包括转子，定子和与定子相关联的开关/检测系统。定子包括三个独立的定子区段，每个独立的定子区段包括多个独立的定子线圈转子包括围绕其周边的多个转子磁极。转子被固定到发动机的挠性板上，并且定子部分被固定到车辆动力传动系的钟罩上。定子线圈各自突出形成在钟形壳体中的开口，使得当转子旋转时，转子极紧靠定子线圈而不接触定子线圈。切换/检测系统用于检测转子磁极相对于定子线圈的位置，并且选择性地给定组线圈定出非常短暂的预定时间间隔，以引起转子的移动，从而有助于启动发动机。在交流发电机模式下，定子线圈产生的能量返回到车辆电池。在发动机稳定模式中，选定的定子线圈组被周期性地通电，以帮助在低怠速下平滑车辆发动机的怠速。该装置和方法还可以用于推动车辆由存储在车辆电池中的能量确定的距离，以用作补充“动力助力器”，并用作用于实现动力系制动的制动器。
