Abstract
The steering movement of a motor vehicle is translated into an electrical signal which increases as the steering wheel rotates in one direction and decreases as the steering operation is reversed. This signal is applied to a minimum value detecting and storage circuit and a maximum value detecting and storage circuit, each including a storage capacitor, a switching diode for controlling the charge or discharge of the capacitor, and a bypass switching circuit connected across the diode. The diode of the minimum detector is connected such that it allows the capacitor to be discharged, while the diode of the maximum detector allows the capacitor to be charged. The bypass switching circuit of the minimum detector provides a charging path to the capacitor, while the bypass circuit of the maximum detector provides a discharging path to the capacitor. The voltages developed across the two capacitors are measured and compared with a reference voltage. A reset signal will be produced when the difference voltage exceeds the reference voltage. The reset signal is used to operate the two bypass switching circuits simultaneously to reset either of the stored values depending upon the instantaneous values of the electrical signal.
