Abstract
Methods, apparatus, systems and articles of manufacture are disclosed for automatic calibration of electronic trailer brake gain. An example apparatus includes a trailer brake gain calibration module programmed to compare a calculated trailer brake torque to at least one of a first or second threshold, adjust a gain value based upon satisfaction of at least one of the first or second threshold, and apply a pressure to a trailer brake based on the gain value.
Claims17
An apparatus comprising:
- a threshold comparator to compare a calculated trailer brake torque to at least a first or a second threshold;
- a gain adjustment manager to:
- adjust a gain value based upon the calculated trailer brake torque satisfying at least one of the first or second thresholds;
- increase the gain value when the calculated trailer brake torque is less than the first threshold;
- decrease the gain value when the calculated trailer brake torque is greater than the second threshold;
- and
- set the gain value as a calibrated gain value when the calculated trailer brake torque is greater than the first threshold and less than the second threshold;
- and
- a brake signal applicator to generate a signal corresponding to a pressure to apply to a brake of a trailer based on the gain value.

A method comprising:
- comparing a calculated trailer brake torque to at least a first threshold or a second threshold;
- adjusting a gain value based upon the calculated trailer brake torque satisfying at least one of the first threshold or the second threshold;
- in response to determining the calculated trailer brake torque is less than the first threshold, increasing the gain value;
- in response to determining the calculated trailer brake torque is greater than the second threshold, decreasing the gain value;
- and
- in response to determining the calculated trailer brake torque is greater than the first threshold and less than the second threshold, setting the gain value as a calibrated gain value;
- and
- applying a pressure to a brake of a trailer based on the gain value.
