1. A gearshift to transmission controller interface comprising:
- a controller area network;
operator transmission controls;
a shift controller coupled to the operator transmission controls and to the controller area network, the shift controller including logic means for determining operator selections input through the operator transmission controls and memory accessible by the logic means storing a library matching possible operator selections with message types and for sending messages identifying operator selections over the controller area network; and
a transmission control module coupled to the controller area network for receiving messages identifying operator selections and programmed to respond thereto, and for generating transmission status signals and sending the transmission status signals over the controller area network.

Abstract
A gearshift to transmission controller interface is based on a controller area network and a gearshift interface interposed between the gearshift and associated displays and the network bus. The shift controller can be made universal to all transmission types of automated manual transmissions by incorporation of a library program relating to a transmission type.

7. A mobile vehicle comprising:
-
a manual transmission; a controller area network data bus; a plurality of vocational controllers connected for communication over the controller area network data bus, the plurality of vocational controllers including a transmission control module also coupled to the manual transmission for the control thereof; a transmission status display; operator instrumentalities for control of the manual transmission; and a shift controller connected to the transmission status display for providing indications of transmission status to an operator and further connected to the operator instrumentalities for receiving operator inputs and still further connected to the controller area network for transmitting and receiving messages from at least one of the plurality of vocational controllers, the shift controller providing an interface between the operator instrumentalities and the automated manual transmission controller with the shift controller including a library of message types categorized by transmission type for generating controller area network messages responsive to the operator instrumentalities where the shift controller determines the transmission type from the transmission control module over the controller area network. - View Dependent Claims (8, 9, 10, 11, 12)
