Abstract:
1. A clutch controlling apparatus, comprising: a shift change transmission having a plurality of gear trains between a main shaft on an input side and a countershaft on an output side; and a clutch configured to selectively control transmission of power between said shift change transmission and an engine between engagement and disengagement, wherein the clutch controlling apparatus is configured to automatically control said clutch upon shift change of said shift change transmission, wherein an input/output power ratio (R) is calculated as a ratio between a rotation of the engine and a rotation of the countershaft, and wherein if the input/output power ratio exceeds a predetermined value in a direction of a rise of the rotation of said engine during shift change of said shift change transmission, then a target control amount of said clutch is corrected in a clutch engagement direction, wherein if elapsed time after shift change of said shift change transmission is started exceeds predetermined time, then the degree by which a correction in the clutch engagement direction is carried out is increased, and wherein the predetermined time has a value obtained by multiplying shift change completion time by a predetermined coefficient, wherein a clutch shift change torque is calculated by subtracting an engine torque estimated value from a target clutch capacity upon starting of the shift change, wherein
