A method for determining a kiss point is disclosed. A drive unit having one or more motors with a motor output shaft is provided. One or more actuation profiles are ran and an amount of motor current and motor shaft position data is measured. The data measured is filtered and one or more motor current vs. motor shaft position plots having one or more curves with a high force and high current region are generated. A derivative is calculated over the curves and a slope of the high force and high current region is determined. A relative slope threshold is determined by multiplying the slopes by a predetermined percentage. One or more lines having a slope substantially equal to the relative slope threshold are plotted. The kiss point is determined based on the position of the motor shaft where the derivative of the curves equals the slope of the lines plotted.

A method determines the biting point of a hybrid disconnect clutch of a hybrid vehicle. The hybrid disconnect clutch disconnects or connects an internal combustion engine and a first electric motor, which is arranged on the output side. A second electric motor, which is arranged on the internal combustion engine side and is rigidly connected to the internal combustion engine, is operated at a constant rotational speed during electric travel by means of the first electric motor. The hybrid disconnect clutch is moved from the open state toward the closed state and the load on the second electric motor is monitored. When the load on the second electric motor reaches a predefined load threshold value, it is determined that the biting point has been reached.

A method of setting a clutch control reference value may make it possible to more accurately learn the VKP of a hydraulic multi-plate clutch controlled by a solenoid valve, improving the accuracy of clutch control, and furthermore, to improve the quality of shifting a vehicle by the precise control of a transmission provided with such a clutch.

The present invention teaches an apparatus for consistent and accurate on-site readings of fluorescence signals of coronavirus test result, with which a user directly reads a fluorescent light qualitatively instead of using electronic sensors. The fluorescent light is excited from a fluorescent source in a site of interest in a target assay. The device comprises a light source for generating an excitation light for exciting the fluorescent source of the target assay to generate a fluorescent light, a component for accurately transmitting the excitation light and the fluorescent light with less noise or reflection, a component for consistent detecting of the fluorescent source by bare eyes with minimal health risks, and a user control system that requires minimal training.

Disclosed is a clutch control reference value setting method including generating a current-hydraulic pressure model, setting a temporary VKP to a current causing a maximum difference between a model hydraulic pressure and a measured hydraulic pressure, determining that the temporary VKP is valid when a deflection amount calculated from a difference integral value acquired by integrating differences between the model hydraulic pressure and the measured hydraulic pressure while increasing the current is greater than a first reference value under a condition that the first target pressure is applied to the clutch, determining that the temporary VKP is appropriate when a deflection amount calculated from a difference integral value acquired by integrating differences between the model hydraulic pressure and the measured hydraulic pressure while increasing the current is proper under a condition that a second target pressure is applied to the clutch.
