Abstract: The degradation of a feeling of ride is prevented by preventing engagement/disengagement (sudden engagement/disengagement) of a motorcycle hydraulic clutch due to a lack of hydraulic pressure. Before a hydraulic sensor issues a hydraulic pressure-lowering detection signal Sx, an oil level sensor issues an oil level-lowering warning signal Sf in a state wherein a sufficient oil quantity is such so as not to bring an neutral drive switching clutch into a disengagement state is present even if hydraulic pressure lowers resulting from an inclined oil level due to sudden deceleration, sudden start, drive in a slope, or the like. Thus, the neutral drive switching clutch can be prevented from disengaging or engaging (suddenly disengaging or engaging).

Abstract: A system for verifying fuel cap engagement utilizes a transducer coupled to a purge line of a fuel vapor recovery system to generate an electrical signal corresponding to one of the vapor pressure and the vapor flow rate in the purge line. A monitor receives the electrical signal and estimates the vapor pressure when the electrical signal corresponds to the vapor flow rate. The monitor likewise estimates the vapor flow rate when the electrical signal corresponds to the vapor pressure. The monitor also correlates the electrical signal and the estimate to generate a dataset relating vapor pressures to corresponding vapor flow rates at predetermined time intervals, computes a linear approximation of pressure versus flow rate, and computes a curve approximation of pressure versus flow rate. An indicator is actuated by the monitor when the difference between the computed linear and curve approximations is less than a predetermined threshold value.

Abstract: Method for monitoring an electrohydraulic braking system. The volume uptake is determined by the elasticity within the wheel brake that is subjected to certain fluctuations, on the one hand, and to a much greater degree by the clearance that is present, on the other hand. To make a reliable statement relating to the air charge, an estimation of the current clearance is first made, taking three ranges into consideration. If there is a normal clearance, a top evaluation threshold is taken as a basis, which assumes the clearance lies at the upper end of the normal range. When said evaluation threshold is exceeded, an alarm is triggered. If the clearance is assumed to lie at the bottom limit of the normal range, a bottom evaluation threshold applies, however, an alarm is only triggered in this case this situation has occurred several times in succession.
