I have some Odometry data taken from a Volkswagen Passat which gives the position. This is calculated using wheel ticks and in addition, I also have data which gives me the number of wheel impulses at each wheel. But unfortunately, I'm confused as to what they actually are. My question is, what are wheel ticks and wheel impulses?
I wasn't able to get much information online other than a whole set of references to wheel speed sensors and hence, posting on this site. Does that mean, wheel impulses give the wheel speed? (rpm)
