该博客介绍了一种用于电动助力车辆转向系统的控制单元，该单元包含两个微处理器控制器，用于监控车速和转向柱扭矩，以计算助力电机的工作周期。通过车速和扭矩输入的响应可以调整，四个控制开关设置在车辆仪表板上进行调整。每个微处理器不仅计算最佳电机激励，还监控电机性能。如果电机性能偏离预期范围，将移除助力，并采取校正措施。EEROM存储用于计算激励序列的常数和控制单元性能指标，辅助诊断问题。
摘要：
A power steering control unit for use with an electric motor assisted vehicle power steering system. The control unit includes two microprocessor controllers that monitor vehicle speed and a torque applied through a vehicle steering column in calculating a duty cycle for the assist motor. The response to the speeed and torque inputs can be adjusted by setting a group of four control switches on the vehicle dashboard. Each microprocessor not only calculates an optimum motor energization but also monitors motor performance. In the event this performance deviates from an expected range the assist is removed and in some cases corrective steps taken to correct the unit's performance. An electrically erasable read only memory coupled to the microprocessors stores constants needed in calculating an energization sequence. The EEROM also stores indicators of the control unit performance to aid in diagnosing difficulties.
