Virtual Turn sensor for electric motor

Code dedicated to the electric motor and its disengagement in the event of an error accumulating on the setpoint.

Define a new virtual steering wheel rotation sensor that can be adjusted in the AgOpenGPS parameters.

During self-steering, the WAS evaluates the error in the WAS setpoint (wheel angle sensor): If the error is maintained or reduced, this can be considered normal. But if the error increases more and more, it is an abnormal situation: such as the steering wheel being taken over manually or the steering sensor having a problem.

This code checks the evolution of the error and accumulates an index according to the abnormal situation.
The result is that it stops the autosteer if the value of the steering wheel rotation sensor is greater than the index.

Depending on the quality of the AgopenGPS response and the hardware, we can set the value of the turn sensor between 30 and 60.

Because it is based of number of error the autosteer will be disengaged with 0.6-1.2s and it will be link according your electric motor and reactivity setting

In case you are not satisfied you can set off turn sensor to cancel the function

if you can test it can you report your setting ? or report that it is not good

Due to my experiance I think the most dificult is on line with very few modification … that probbably we can add 1-0.5% error comparaison

File available

for Switch mode and autosteer stop (code from @m_elias ) permit to use Switch in this case


Note the compiled HEX is NOT up to date on my repo

Small update and first feed back

Probably not the best but give a level more of safety in case of
need to adjut steering more aggresif on the line than soft to try to control the steering

In 24V the time to disconnect can be burn the fuse if you use voltage transformer
so less agressivity with max load for that can be a solution
