Abstract:
The present teaching aims to provide: a cam angle sensor fault diagnosis apparatus for straddled vehicle, capable of detecting a fault of a cam angle sensor installed in a straddled vehicle and guessing a fault place; an engine system; and a straddled vehicle. A cam angle sensor fault diagnosis apparatus for straddled vehicle includes: a cam signal receiving unit connected to a signal output line through which a cam angle sensor outputs a cam signal in accordance with the rotation angle, the cam signal receiving unit being configured to receive a cam signal via the signal output line; a state determination unit that determines one or two fault states of the cam angle sensor from a disconnection state, a power supply fault state, and a ground fault state, distinguishably from the other fault states, in accordance with a signal level of a cam signal received by the cam signal receiving unit; and a signal output unit that outputs a fault signal representing the one or two fault states determined by the state determination unit, in such a manner that the fault signal representing the one or two fault states is different from a fault signal representing the other fault states.

Claim (Index 8):
The cam angle sensor fault diagnosis apparatus for the straddled vehicle according to  claim 1 , wherein\n when the cam angle sensor is not in any of the disconnection state, the power supply fault state, and the ground fault state, the cam signal receiving unit receives the cam signal from the cam angle sensor such that a high signal level holding period in which the cam signal having a high signal level is received and a low signal level holding period in which the cam signal having a low signal level is received alternately and continuously appear and such that the sum of one high signal level holding period and one low signal level holding period that are continuous with each other substantially matches a period of 720 crank angle degrees in the engine or is shorter than the period of 720 crank angle degrees, in the high signal level holding period and the low signal level holding period that alternately and continuously appear, the state determination unit repeats a determination of a fault state based on the length of the high signal level holding period and a determination of a fault state based on the length of the low signal level holding period so as to satisfy all of requirements (i) to (iii) that: (i) a fault state determined based on the length of the high signal level holding period and a fault state determined based on the length of the low signal level holding period are different from each other; (ii) a fault state determined based on the length of the high signal level holding period is distinguished from a fault state other than the fault state determined based on the length of the high signal level holding period; and (iii) a fault state determined based on the length of the low signal level holding period is distinguished from a fault state other than the fault state determined based on the length of the low signal level holding period, and the signal output unit outputs the fault signal so as to satisfy all of requirements (I) to (III) that: (I) the fault signal representing the fault state determined based on the length of the high signal level holding period and the fault signal representing the fault state determined based on the length of the low signal level holding period are different from each other; (II) the fault signal representing the fault state determined based on the length of the high signal level holding period is distinguished from the fault signal representing the fault state other than the fault state determined based on the length of the high signal level holding period; and (III) the fault signal representing the fault state determined based on the length of the low signal level holding period is distinguished from the fault signal representing the fault state other than the fault state determined based on the length of the low signal level holding period.
