Remote Control for Mobile Machine, In Particular for Public Works Machine, Agricultural or Load-Handling Machine

A method of checking the operation of a processing unit of a mobile machine remote control, in particular for public works machine, agricultural or load-handling machine, intended to generate control signals towards a client device, by way of communication means, the remote control comprising:

• a movable control handle that can move according to at least one degree of freedom with respect to the body of the remote control,
• at least one sensor of the position of the control handle,
• a unit for processing the signals emitted by the at least one sensor,
• an actuator, intended to transmit control signals, processed by the processing unit to the client device,
• method comprising the steps consisting in,
• at the level of a client device:
• emitting a test signal destined for the processing unit,
• at the level of the remote control:
• producing a signal derived from the test signal emitted by the client device
• introducing the derived signal as input for the processing unit,
• processing the signal derived from the test signal as a sensor signal at the level of the processing unit,
• emitting an information set, comprising at least one response signal corresponding to the processing by the processing unit, of the signal derived from the test signal, towards the client device,
• at the level of the client device:
• comparing the test signal and the response signal.
