Abstract

PURPOSE:To detect shift timing without delay by comparing a value of torque on the driving side with a value of torque on the absorber side which can be calculated as described. CONSTITUTION:Let the transfer factor by means of a torque converter 8 be equal to f(N1, 2H2), then Trq2=Trq1Xf(N1, alphaH2)XalphaH2/H2 where Trq1=value of transfer torque of drive system alpha=gear ratio of transmission gearing N2= rpm of absorbers such as flywheel, etc. Trq2=value of torque of absorber 5 Thus, the shift timing can be detected by comparing a value of torque on the driving side Trq1 with a value of torque on the absorber side Trq2 which can be calculated using the equation above.
