Hi Marcus, Thanks a lot for your email ! With setting "tau" to the value 0, my vehicle ignores the yellow traffic light ;-) exactly what I wanted ! Many thanks !!
I hope you'll find a solution for your simulations, Best Regards and good luck ;-) Marie-Ange 2014-09-03 20:49 GMT+02:00 Marcus Müller <[email protected]>: > Hi Marie, Hi guys, > > > > I’m sorry to say, but I still was not successful on getting this „*speed > mode*“ bits set.
