发明名称 Control unit and method to operate a vehicle
摘要 A control unit of a motor vehicle for activating a form-locking shift element of a transmission of the motor vehicle in such a way that a defined rotational speed difference is defined, between an input-side component of the form-locking shift element and an output-side component of the form-locking shift element, in order to engage the form-locking shift element. The control unit monitors the rotational speed gradient of the rotational speed of the output-side component of the form-locking shift element from an activation time of the form-locking shift element, at which the engagement process of the form-locking shift element begins. The control unit generates a control signal for a drive assembly in order to increase the torque, at a drive assembly, in the event that the control unit determines that the monitored rotational speed gradient falls below a lower limit.
