Title:
LINEAR SOLENOID VALVE CURRENT CONTROL METHOD
Document Type and Number:
Japanese Patent JP2017180768
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a linear solenoid valve current control method capable of making PWM period variable and after this processing, capable of realizing a superior hydraulic control.SOLUTION: A linear solenoid valve current control method modulating a coil current with pulse width for driving linear solenoids of linear solenoid valves [107a, 107b] for adjusting pressure of working oil of hydraulic type clutches [CL1, CL2] for disconnecting or connecting rotational driving force transmitted from a power force source of a vehicle to a driving wheel is operated in such a way that a period of the pulse width modulation is set to be short as a connection degree from a disconnected state of the hydraulic clutches [CL1, CL2] becomes large [S31, S32, S33]. In this case, it is also applicable that the period of pulse width modulation is set in response to a variation in duty ratio corresponding to the hydraulic pressure corresponding to the connection degree.SELECTED DRAWING: Figure 11
