Abstract: PURPOSE:To improve the accuracy of the numerical value of an odometer by providing an EEPROM additionally and writing only the high-order digits of run distance in respective address as data, and displaying the low-order digits by utilizing the addresses themselves. CONSTITUTION:The odometer on a vehicle counts a signal from a run distance sensor which generates a signal regarding the number of rotation of a shaft, etc., and then displays integral run distance. In this case, the output pulse signal of the run distance sensor is inputted to a CPU to count the number of pulses, and writing to the EEPROM and display output of a display device are performed at specific intervals of distance. Then when the high-order digits (high-order four digits when six digits, i.e. 100km) of the integral run distance are written in respective addresses 00-99 of the EEPROM and rewriting is performed at every 100km, that there are only two kinds of data in the respective addresses in principle. Then, the data in the addresses, i.e. integral run distance consisting of the high-order four digits and two digits of their addresses is displayed on the display device. Therefore, the update of the EEPROM is reduced by the utilization of the addresses and the data is discriminated securely.

IPC: H02M1/08
Filed: 1978-04-19
Abstract: PURPOSE: To give a digital controller, which controls the ignition phase of a thyristor converter by using a control computer, a fail-safe function in the method of stopping the supply of an ignition pulse when the controller gets out of order.  
     CONSTITUTION: A state signal indicates a normal operation with logic "1" and a failure with "0"; in case that the control computer gets out of order, no signal is applied to load terminal L of counter 24 and the output of divider circuit 20 is to clock input C 1 . As a result, counter 24 counts up and according to it, an ignition pulse to thyristor converter 2 increases in phase angle. With the discrete value at its maximum, a carry signal is outputted to reset flip-flop 25. Consequently, no logical condition between ANDs 14 and 15 is established and the supply of the ignition pulse stops, so that the thyristor converter will stop safely.
