Trouble countermeasure method using change of target shape

摘要

A target to be mounted on a camshaft has a high portion of 180 degrees and a low portion of 180 degrees. The rotation of the target tooth is read from the face sensor, and the ECU Reads the signal from the phase sensor and starts at the point Pn when the CAS signal fails and judges whether Pn-1 = 0 and outputs t_pn= t_pn-1And judges whether t'pn = t_pn/ 2, it is input to the ECU to output the ignition and injection signals. After that, when n = n + 1, CAS confirms that the failure has occurred and repeats the above procedure if NO, / RTI
