Abstract
A trailer oscillation and stability control device including an accelerometer and an angular rate sensor. An oscillation detection discriminator detects oscillatory lateral trailer motion in response to trailer displacement data derived from inputs from the angular rate sensor and acceleration signals received from the accelerometer, and then generates corresponding oscillatory event data. A brake controller generates a braking control signal in response to oscillatory event data received from the oscillation detection discriminator.
