Abstract

A trailer brake control system which includes a variable frequency oscillator, an electromagnetic inertial sensor adapted to detect either lateral acceleration or longitudinal deceleration of a trailer and to vary the output frequency of the oscillator in accordance therewith, and a circuit for applying trailer brakes as a function of such frequency variation either to correct a trailer sway condition indicated by lateral trailer acceleration or when tractor brakes have been applied as indicated by longitudinal deceleration of the tractor/trailer combination.
