Embodiment Construction

[0028] Embodiments of the invention with further developments described hereinafter are to be considered as examples only and in no way limit the scope of protection offered by the patent claims.

[0029] The invention relates to a method for enabling at least one function stored in a vehicle communication system in a heavy vehicle or working machine. Hereinafter, a heavy vehicle or working machine will be referred to as a "vehicle". The invention also relates to a vehicle communication system and a vehicle with an actuator. Hereinafter, actuators will be referred to as "input devices" and may include switches, rotary switches, joysticks or any other device in a vehicle for user-assisted control of functions.

[0030] Even though the detailed description substantially describes methods performed by systems and input devices, those skilled in the art will recognize that systems and input devices suitable for performing these method steps are also disclosed in the specification...

Abstract

The present invention relates to a method for enabling at least one function being stored in a vehicle communication system in a heavy vehicle or working machine. The system comprises information about each function and information about a respective output signal relating to each function, The system further comprises information about a respective function identity code unique for each function, the method comprising the steps of: - a master Electronic Control Unit, ECU, in the system, receives (17) an actuator identity code which relates to an actuator connected to the system, - the master ECU compares (18) the received actuator identity code with the function identity codes, - the master ECU assigns (19) a function with a function identity code that corresponds with the actuator identity code so that the actuator is enabled to control the output signal relating to the assigned function.

Description

technical field [0001] The invention relates to a method for enabling at least one function stored in a vehicle communication system in a heavy vehicle or working machine. The invention also relates to a vehicle communication system and a heavy vehicle or working machine employed for the same purpose. Background technique [0002] A heavy vehicle or work machine, such as a truck or wheel loader, can serve many different functions. A function can be any output in an electrical control unit (ECU) in a cruise control or vehicle communication system. The ECU can in turn control a relay to activate a hydraulic oil pump to a crane or similar. Each function is implemented by a system consisting of one or more electrical control units (ECUs). The same ECU is often used for other functions as well, so the software supports several different functions. [0003] Many heavy vehicles delivered to customers first go to a bodybuilder that assembles additional features, such as a dump b...
