Abstract: A basic pulse time setting section determines a basic pulse time for initial invalid stroke elimination by applying current values of oil temperature and throttle opening to the basic pulse time map. A subtraction time setting section determines a subtraction time by applying current values of oil temperature and clutch oil pressure to the subtraction time map. A pulse time determining section determines a predetermined initial invalid stroke elimination pulse time by subtracting the subtraction time from the basic pulse time. An initial invalid stroke elimination permission/inhibition determination section, at a starting timing of initial invalid stroke elimination, inhibits this-time initial invalid stroke elimination if the elapsed time from the execution timing of the preceding initial invalid stroke elimination is within the predetermined inhibition period.
