摘要： An AC motor control based on an iterative computation of the motor load and method of accurately determining motor load. At the initiation of motor operation, the load term (%LOAD) is initialized to zero, and the motor is energized in accordance with a predetermined voltage and frequency schedule for producing motor rotation. During the starting interval the power loss term LOSSES and the load term (%LOAD) are iteratively computed as a function of the input voltage and current (V.sub.bus, I.sub.bus) and the motor inverter frequency (IF). When a predetermined motor speed has been achieved, the run mode is initiated. At this point, the load is known based on the iterative load calculations performed during starting, and the motor voltage and inverter frequency are scheduled as a function of motor speed and load. The iterative computation of losses and load continue during the run mode so that changes in the motor load are taken into account.

摘要： A motor vehicle suspension control includes a solenoid actuator having an actuating coil connected in series with a transistor across an electric power source and circuit protection apparatus for the transistor. The voltage across the transistor is monitored, after a short time delay following turn-on, as a signal indicative of excessive current therethrough. If the signal so indicates, the transistor is turned off for a period of time and then turned on again for another try. This continues for a predetermined maximum number of attempts. Specific clocked digital circuitry is disclosed for controlling the operation and producing the different required time delays or counts.

摘要： Power antenna control apparatus is disclosed for a vehicle having an ignition switch with off, run and start positions, engine start means responsive to the ignition switch in its start position, a radio receiver effective to generate an extend signal when activated and a retract signal when deactivated and means effective to deactivate the radio receiver with the ignition switch in its off and start positions. The control comprises control means responsive to the extend and retract signals to activate the drive means toward, respectively, fully extended and retracted antenna positions and further comprises control means responsive to the ignition switch in its start position to deactivate the drive means at least in the extend direction and for at least a predetermined period of time deemed sufficient for engine starting, whereby reversal of antenna extension during engine starting is prevented. The last control means may be deactivated when the antenna is in its fully extended position to permit immediate antenna retraction when the ignition switch is turned off.

摘要： A power antenna control for a motor vehicle comprises a Hall effect device responsive to motor armature rotation to generate pulses for equal predetermined increments of antenna travel. These pulses are applied to both position and stall counters. In extension, the antenna drive is stopped when the position counter reaches a number corresponding to a predetermined extended position, which may be full extension or some lesser extension. In retraction, the stall counter is used with a clock to indicate stall which, when detected, causes the antenna drive to be stopped. Automatic current limiting for drive torque limitation during stall is activated only when the position counter indicates a limited position range near full retraction. Further during retraction, if the antenna is stopped within a small position range of full rectraction, it is reset to a count indicating full retraction. The system eliminates the need for hard stall sensing reaction switches and thus reduces antenna drive cable fatigue.
摘要翻译：用于机动车辆的功率天线控制器包括响应于电机电枢旋转的霍尔效应装置，以产生等于天线行进的预定增量的脉冲。这些脉冲施加到位置和停止计数器。在扩展中，当位置计数器达到对应于预定延伸位置的数字时，天线驱动器停止，该预定延伸位置可以是完全扩展或者较小的延伸。在收回时，停止计数器与时钟一起使用以指示停止，当被检测到时，使天线驱动器停止。只有当位置计数器指示接近完全缩回的有限位置范围时，才会激活停止期间驱动转矩限制的自动限流。进一步在缩回过程中，如果天线在完全向下的小位置范围内停止，则将其重置为指示完全缩回的计数。该系统消除了对硬停止感测反应开关的需要，从而减少了天线驱动电缆的疲劳。

摘要： Motor control apparatus is disclosed for a motor driven vehicle power window mechanism including a flexible drive element, such as a drive tape, adapted to drive the window in a predetermined direction by being placed in tension by the motor. The tension of the flexible drive element is relieved by automatically reversing motor direction for a short time when the window reaches the desired position. The reverse motor rotation is accurately controlled to an amount sufficient to relieve drive tension but insufficient to produce unwanted reverse movement of the window by detecting the pulses of the armature ripple current as the successive commutator bars pass the brushes during reverse motor rotation, integrating these pulses and stopping the reverse motor operation when the integrated value reaches a predetermined reference.

摘要： A resistor (having a resistance of Rs) is connected in series with an inductor whose inductance and/or resistance is desired to be determined. An alternating voltage (such as a sinusoidal voltage) is applied across the series-connected resistor and inductor, wherein the alternating voltage has a frequency ω, a unique maximum or minimum value Vm, an average value and a unique crossover of the average value. The voltage Vr is measured across the resistor when the alternating voltage is at its maximum or minimum value. The voltage Vl is measured across the resistor when the alternating voltage is at its average value. The resistance RL of the inductor is calculated from an equation in which RL is a function of Vm, Vr, Rs and Vl. The inductance L of the inductor is calculated from an equation in which L is a function of Vl, Rl, Rs, Vr and ω.

摘要： A voltage regulating control system for vehicle systems which includes a power supply providing electrical power to the system and having a predefined maximum voltage. A controller controls an actuator performing a vehicle system function and the electrical load in the system wherein the controller has a first predefined minimum operating voltage. A voltage regulator communicates with the controller and the power supply and senses a system input voltage in the system. In response to a sensed voltage dip in excess of a predetermined value, the regulator changes an effective electrical impedance of the system to maintain the system voltage at a predefined minimum voltage greater than the first predefined minimum operating voltage required by the controller.
