Abstract
Methods, apparatus, systems and articles of manufacture are disclosed for automatically calibrating electronic trailer brake gain. An example apparatus includes a trailer brake gain calibrator programmed to modulate a trailer brake gain value based upon a derivative of a trailer hitch force and apply a pressure to a brake of a trailer based on the gain value.
Claims17
An apparatus comprising:
- a hitch force derivative calculator to calculate a derivative of a hitch force of a trailer coupled to a vehicle;
- a gain adjustment manager to adjust a gain value based upon the derivative of the hitch force;
- a brake pressure applicator to apply a pressure to a brake of the trailer based on the gain value;
- a data interface to receive status information of the vehicle, the status information including at least one of anti-lock brake data, traction control data, vehicle stability control data, moisture data, temperature data, hitch force data, or key cycle data;
- and
- a gain calibration initializer to initialize adjustment of the gain value based upon the status information of the vehicle.

An apparatus comprising:
- a trailer brake gain calibrator programmed to modulate a trailer brake gain value based upon a derivative of a trailer hitch force and apply a pressure to a brake of a trailer based on the gain value;
- and initialize a gain calibration routine based on status information of a vehicle including at least one of anti-lock brake data, traction control data, vehicle stability control data, moisture data, temperature data, hitch force data, or key cycle data.
A method comprising:
- calculating a derivative of a hitch force;
- adjusting a gain value based upon the derivative of the hitch force;
- modulating a pressure applied to a trailer brake based upon the gain value;
- and initializing a gain calibration routine based upon status information of a vehicle, wherein the status information of the vehicle further includes at least one of anti-lock brake data, traction control data, vehicle stability control data, moisture data, temperature data, hitch force data, or key cycle data.
