A method for determining an output torque in a drive system capable of being power shifted in a vehicle includes providing the drive system having a drive unit for transmitting the drive torque, a dual clutch having a first clutch and a second clutch, and a power shift transmission. The power shift transmission has a first gear with a first gear ratio and a second gear with a second gear ratio. The method also includes measuring a first torque transmitted by the first clutch, calculating a distribution of the drive torque to the first clutch and the second clutch using the first torque, and determining the output torque from the distribution of the drive torque.

A method (200) for the open-loop control of a gearbox (100) that includes a first and a second proportionally controllable shift element (A-F) is provided. The method includes disengaging (215) the first shift element (A-F) according to a first control profile and engaging (220) the second shift element (A-F) of the gearbox (100) according to a second control profile. The first control profile includes a first variable portion which is determined as a function of a temperature of the gearbox (100).

A drive-train of a vehicle which at least includes a drive motor (1) and a transmission (2). The drive-train has at least one torque sensor (6, 6A) which is provided for the purpose of controlling a drive component of the drive-train. The torque sensor (6, 6A) is integrated in a transmission component in order to determine, at the time, the torque applied to the transmission component.

A method for determining a clutch engagement ratio for a vehicle having at least a front wheel and a rear wheel, a motor, a transmission, and a clutch coupling the motor to the transmission. The method may include receiving, at a controller, an output transmission speed. The method may include receiving, at the controller, an input transmission speed. The method may include calculating, with the controller, a transmission speed ratio by comparing the output transmission speed to the input transmission speed. The method may include receiving, at the controller, a currently engaged gear in the transmission. The method may include extracting, with the controller, a gear speed ratio associated with the currently engaged gear. The method may compare the transmission speed ratio to the gear speed ratio. The method may extrapolate a clutch engagement ratio. The method may determine a clutch condition.
