Abstract:
1. A power transmission control device for a vehicle, which is to be used for a vehicle comprising a first power source and a second power source, the power transmission control device comprising: a transmission including an input shaft for inputting a power from an output shaft of the first power source and an output shaft for outputting the power to a drive wheel of the vehicle, the second power source having an output shaft connected to the input shaft or the output shaft; a friction clutch interposed between the output shaft of the first power source and the input shaft of the transmission, for realizing a fully engaged state in which the power is transmitted without a slip when a clutch operation member to be operated by a driver is not operated and for realizing a partially engaged state in which the power is transmitted with the slip in accordance with an operation amount of the clutch operation member or a fully disengaged state in which the power is not transmitted; first detection means for detecting an operation amount of an acceleration operation member for accelerating the vehicle, the acceleration operation member being to be operated by the driver; second detection means for detecting the operation amount of the clutch operation member; and control means for controlling a first torque corresponding to a driving torque for the output shaft of the first power source and a second torque corresponding to a driving torque for the output shaft of the second power source, wherein the control means comprises: wherein the control means is configured to adjust the second torque to a second torque final reference value corresponding to a smaller one of the determined second torque reference value and the determined second torque limit value, wherein the control means is configured to, in a case where the first torque is maintained to zero by stop of the first power source, and the vehicle runs by drive of the second power source by using only the second torque which is generated by the second power source, when the friction clutch transitions from the fully engaged state through the partially engaged state, the fully disengaged state, and the partially engaged state to return to the fully engaged state by the operation of the clutch operation member for a shift operation of the transmission, detect a timing at which the friction clutch transitions from the partially engaged state to the fully disengaged state based on the detected operation amount of the clutch operation member so as to adjust the second torque to a value shifted from the second torque final reference value in synchronization with the detected timing.
