Hi,

 

Regarding the driver state device:

 

 

 

 

  1. How is the error(t) scaled, do we give input for this? Is this the same with device.driverstate.errorState?

 

  1. Default value for speedDifferenceErrorCoefficien is 0.15, what is the range for this?

 

 

 

Before, I asked about the definition and range of the "device.driverstate.errorState" parameter. The answer that I got was this: ErrorState gives the magnitude and direction of the relative error in gap estimation. The state tends toward 0 in the long run but there is no limit to how far it may deviate from 0.

 

  1. My questions are: Does it affect only the gap estimation? Why it tends to zero over the time, does it represent something in real life? With what rate it tends to zero? (I want to see the mathematical calculation, for example when I set errorState to 10 how much the real gap and faulty one are different).

 

Btw, I have checked "MSDriverState" file but could not find the answer for my questions.

 

 

 

Best regards,

Mehdi
