modelMinimalChassis3
Basic chassis model with rigid connection between all 4 wheels, uses chassisFrame connection, includes wheel bearings
Extends from MinimalChassis2 (Basic chassis model with rigid connection between all 4 wheels, uses chassisFrame connection).
Information
Single degree-of-freedom chassis model with mass and speed dependant drag model. Uses MultiBody wheelHub connections and positions these relative to the vehicle body position.
