Abstract: A shift safety device for a manual transmission having a gear shift shaft that rotates to select shift gates and moves to shift gears. The device has a blocking element which, during selector motion towards a shift gate, is driven by the gear shift shaft, against a spring, from a starting position into a blocked position, in which the device blocks further selector motion of the gearshift shaft, and which, during subsequent shifting motion of the gearshift shaft, is released and returned back to the starting position, by the spring, thereby permitting further selector motion. A driver arm, disposed on the gear shift shaft, moves the blocking element tangential to the arc traversed during selector motion by the driver arm between the starting and blocking positions. The blocking element moves in the linear track traversed during shifting of the driver arm and is pretensioned toward the starting and center positions.

Abstract: A method of operating a motor vehicle having a drive aggregate, a transmission and a hydraulic system. The transmission has shift elements and, for each gear, only a portion of the elements are engaged while a remainder are disengaged. The hydraulic system has main pump driven by the drive aggregate and an auxiliary pump. The method tests the functionality of the auxiliary pump. The drive aggregate and the main pump are insufficiently driven such that the shift elements can not engage. The auxiliary pump is driven to provide required pressure such that all but one of the shift elements fully engages. The remaining shift element is then first engaged up to its engagement point and then either engaged beyond its engagement point or another unengaged shift element is engaged beyond its engagement point. The functionality of the auxiliary pump is determined based on changes in the drive aggregate's rotational speed.

Abstract: A method for operating a transmission of a vehicle drivetrain. A transmission ratio can be automatically changed during an operating state depending on a comparison of current operating state parameters with operating parameters stored in a control unit, and can be manually changed depending on a driver's request. Accordingly when the driver requests a change of the transmission ratio, the transmission ratio changes, and a timer starts. If the driver continues the ratio change from an actual transmission ratio value toward a larger or smaller transmission ratio value, the current operating parameters are compared with the stored operating parameters. Upon this comparison, the transmission shifts to higher ratios in comparison to the operating parameters stored in a control device at higher vehicle speeds, and/or a delay between sequential, cyclical transmission ratio changes varies depending on a vehicle deceleration and/or braking pressure in the region of a vehicle brake.
