    • A microprocessor-based electronic voltage regulation system for controlling the charging of the battery in a vehicle. The conventional voltage regulator is eliminated and the intelligence of the microprocessor already present on the vehicle for controlling engine operation is used to regulate the output of the alternator. The battery temperature signal from a temperature transducer and a battery voltage signal from a sense line connected directly to the positive terminal of the battery are supplied to the microprocessor through an analog-to-digital converter. The microprocessor is programmed to ascertain from the battery temperature signal the desired set point voltage based upon an inverse first order relationship between battery temperature and desired battery voltage with preset maximum and minimum voltage set point levels. Energization of the field windings is controlled in accordance with a comparison between the desired set point voltage and the battery voltage signal on the battery sense line and is implemented in response to a control signal from the microprocessor by a solid-state power switching circuit which interfaces with the alternator field windings. In addition, the microprocessor is provided with additional feedback information relating to various driving conditions, such as vehicle deceleration, throttle position, engine RPM, and elapsed time since ignition, and is further programmed to modify the desired voltage set point or modify engine RPM in accordance with such driving conditions. Overcurrent protection for the logic circuitry and improved diagnostic capabilities are also provided.

    • A regulated power supply for supplying DC output voltage and current to an electronic control system of an internal combustion engine, designed especially for automotive applications and cold cranking conditions encountered therein, is disclosed. The power supply has a series switching regulator section having a transformer provided with two windings, and a shunt switching regulator section that shares the transformer with the series regulator section. When normal battery voltages are available, the power supply through its series regulator section operates in a voltage dropping mode, intermittently passing current through the primary winding of the transformer to maintain the desired output voltage. When low battery voltages are encountered, such as during cold cranking conditions, the shunt regulator section of the power supply operates in a voltage boosting mode to maintain the desired output voltage. The voltage boosting function is accomplished by intermittently shunting current from the primary winding towards ground, and utilizing the resultant magnetic energy stored in the core of the transformer to boost the voltage available to the load. Mutual inductance between the primary and secondary windings allows energy stored in the core of the transformer as a result of current flowing through the primary winding to be beneficially delivered through the secondary winding to the output of the power supply during both modes of power supply operation, thereby improving overall power supply efficiency and reducing power supply cost and complexity.

    • A method of and apparatus for controlling the energization of an electromagnetic fuel injection valve in response to the production of an injector control pulse in an electronic fuel injection system. The driver circuit operates a current regulating power transistor into saturation until the current through the solenoid coil of the injector valve attains a predetermined peak current value. A comparator circuit deactivates the power transistor to stop the build-up of current through the coil. A switched free-wheeling circuit is enabled, remains activated, and starts conducting when the power transistor is deactivated by the comparator circuit so that some current continues to be supplied to the solenoid coil when the power transistor is off, thereby causing the current through the coil to decay slowly. When the solenoid current has decayed to a predetermined hold current level, the comparator circuit reactivates the power transistor and thereafter, due to hysteresis in the comparator circuit, cycles the power transistor on and off to substantially maintain the current through the coil at the predetermined hold current level. At the end of the injector control pulse, both the current regulating power transistor and the switched free-wheeling circuit are deactivated. Then, through multiple power dissipation pathways momentarily activated by the avalanching of a zener diode in series with the injector's solenoid coil, the energy stored in the solenoid coil and the current through the coil diminish rapidly to zero.
    • 一种用于响应于在电子燃料喷射系统中产生喷射器控制脉冲来控制电磁燃料喷射阀的通电的方法和装置。 驱动器电路使电流调节功率晶体管进入饱和状态,直到通过喷射阀的螺线管线圈的电流达到预定的峰值电流值。 比较器电路停用功率晶体管,以阻止电流通过线圈的积聚。 当功率晶体管被比较器电路停用时,切换续流电路被启用,保持激活,并且开始导通,使得当功率晶体管截止时,一些电流继续提供给螺线管线圈,从而使电流通过 线圈慢慢衰减。 当螺线管电流衰减到预定的保持电流电平时,比较器电路使功率晶体管再激活,此后由于比较器电路中的滞后,使功率晶体管开启和关闭,以基本上保持在预定保持时通过线圈的电流 当前水平。 在喷射器控制脉冲结束时,电流调节功率晶体管和切换续流电路都被去激活。 然后,通过与注射器的螺线管线圈串联的齐纳二极管的雪崩瞬间激活的多个功率消耗路径,存储在螺线管线圈中的能量和通过线圈的电流迅速减小到零。
