Abstract
A braking system for a mobile medical diagnostic device having forward support wheels operatively associated with proportional electromechanical brakes and a single central steerable wheel assembly at the rear of the device. Means are provided for generating throttle command signals and actual velocity signals and for comparing the two and for applying current to the proportional brakes to a degree which is proportional to the difference in those two signals. When this difference exceeds a predetermined level, a motor brake is further actuated to augment the proportional braking system. Also included is a means for automatically reducing the throttle command signal in proportion to the degree that the steerable wheel assembly is turned from the straight-ahead position.
