ABSTRACT:
There is provided a starting clutch control apparatus which is capable of controlling transmission torque of a starting clutch according to changes in accelerator operated amount without preparing a plurality of data maps of torque coefficients in advance. A clutch controller determines a clutch instruction torque based on torque coefficient, engine speed, and engine speed correction amount, and controls the engagement state of the starting clutch according to the clutch instruction torque. Therefore, it is possible to control the engagement state of the starting clutch in response to sudden operation of an accelerator, and to finely control the degree of engine blow-up according to an accelerator operated amount. Only one data map for determining the torque coefficient according to a rotational speed ratio of a clutch input shaft to a clutch output shaft is required to be stored in a data storage section, and hence it is possible to prevent an increase in the amount of data stored in the data storage section.
