Abstract
A control system (202) can directly or indirectly measure force applied between a trailer (112) and a prime mover vehicle (102) coupled to the trailer. Based on the measured force, the control system can determine an operational state of one or more features of the trailer. For example, static resistance, rolling resistance, and/or acceleration rate of the trailer can be measured while applying a specific braking actuation level to the service air brakes of the trailer. Based at least in part on the measured static resistance, rolling resistance, and/or acceleration rate, an operational model (206) for actuation of the service air brakes can be applied. In some examples, the control system can be part of the prime mover vehicle, for example, an autonomous vehicle.
