Claim Text:
1. A trailer brake control method, comprising: determining, based on information from a vehicle speed sensor, a current vehicle speed of a vehicle; regardless of the current vehicle speed, determining, using a processing unit, a minimum trailer brake control value (MTBCV) based on the equation MTBCV=R1−Cth root(the current vehicle speed)/R2, wherein the minimum trailer brake control value corresponds to a minimum braking force based on the current vehicle speed, R1 is a real number less than 1.0, C is an integer greater than 2, and R2 is a real number greater than 1.0; determining, using the processing unit, a trailer brake command signal based on the minimum trailer brake control value; and operating brakes of a trailer connected to the vehicle at or above the minimum braking force by transmitting the trailer brake command signal from the vehicle to a trailer.
