Method for Controlling a Gear Change in the Case of a Non-Synchronized Dog-Shift Transmission

A control apparatus for controlling a gear change in a non-synchronized dog-shift transmission having at least one shift fork which is controllable via a selector drum, comprising:

• a position sensor on the selector drum;
• an electronic control unit that receives an input from the position sensor, wherein
• the electronic control unit comprises a program function module executable by a processor to:
• detect a rotational position of the selector drum by way of a position sensor on the selector drum;
• transmit the detected rotational position to an electronic control unit that controls a drive engine;
• determine, via the detected rotational position, whether the shift fork is situated in an intermediate position in which neither of two possible gears assigned to the shift fork is engaged;
• and
• if the shift fork is determined to be in the intermediate position, regulating, via the electronic control unit, the rotational speed of the drive engine to a mean value between target rotational speeds of the two possible gears when a clutch between the drive engine and the dog-shift transmission is open.

An electronic control unit that executes a method to control a gear change in a non-synchronized dog-shift transmission having at least one shift fork which is controllable via a selector drum, the electronic control unit comprising a non-transitory computer readable medium having stored thereon program code that, when executed, carries out the acts of:

• detecting a rotational position of the selector drum by way of a position sensor on the selector drum;
• transmitting the detected rotational position to an electronic control unit that controls a drive engine;
• determining, via the detected rotational position, whether the shift fork is situated in an intermediate position in which neither of two possible gears assigned to the shift fork is engaged;
• and
• if the shift fork is determined to be in the intermediate position, regulating, via the electronic control unit, the rotational speed of the drive engine to a mean value between target rotational speeds of the two possible gears when a clutch between the drive engine and the dog-shift transmission is open.
