regarding the existing Antilock braking system example model.

In the existing Antilock braking system example model.The wheel speed output is mentioned in unit m/s and vehicle speed output is in rad/sec .But actually when i calculated the wheel speed the output unit is rad/sec only . how did m/sec came ,there is no any block or logic near wheel speed discrete function block that converts rad/sec into m/sec . Then why there is a m/sec .The wheel speed and vehicle speed value goes into slip ratio calculation with mismatched units ,won;t this impact the accuracy of the model.please kindly provide a clarification on this.

Click the block masked as "?" to bring up the help document. It explains the unit of vehicle/wheel speed. There is a Gain block "1/Rr" involved to make the conversion.

Gain block is there "1/Rr" only in vehicle speed subsystem .But in wheel speed subsystem there is no such kind of block or conversion happening as observed and help document does not have that detail.This answer didn't clarify my doubt.Inside the wheel speed discrete integrator block parameter there is a gain,but it is not 1/Rr and the initial condition of that block is V0/Rr ,does those got anything to do with unit conversion
