专利汇可以提供Controlling of automobile专利检索,专利查询,专利分析的服务。并且PURPOSE: To eliminate the pulsation of input signal and perform controlling based on the correct value of the input signal, filtering the input signal sampled at a constant period.
CONSTITUTION: Various kinds of analogue signals ocrredsponding to the running conditions of automobile are detected at a constant period and converted into digital signals by an A/D converter. Actuators for controlling the engine are controlled depending on data calculated by a microprocessor on the ground of the digital signals. The digital signals are filtered by a simple arithmetic mean process or exponential smoothing process, as shown in Fig., thereby eliminating the pulsation of the input signals. The signal y represented by the dotted line in Fig. has been filtered. The processing flow chart indicates the exponential smoothing process
