Abstract
A method of controlling a trailer brake system using a trailer brake controller positioned within a passenger vehicle is provided. The method includes obtaining intended braking inputs and developing an effective baseline trailer brake controller output profile based thereon. The method scales the effective baseline trailer brake controller output profile in response to an adjustable gain setting set by an operator. The wheel speed is determined at a plurality of wheel locations and vehicle acceleration is calculated. The vehicle acceleration is utilized to selectively choose one of the wheel speed. The vehicle velocity is based on the selectively chosen wheel speed. The vehicle velocity is used to calculate a correction factor to the effective baseline trailer brake controller output profile. The effective baseline trailer brake controller output profile is then adjusted using the correction factor to generate a corrected trailer brake controller output signal.
