Vehicle trailer detection
First Claim
Patent Images
1. A vehicle comprising:
- an accelerometer;
an electronic stability control unit to;
detect, with the accelerometer, signals indicative of axles traversing a bump;
when at least three axle signals are detected, generate a profile based on a speed of the vehicle and timing of the signals;
based on the profile, determine whether a trailer is connected to the vehicle; and
when the trailer is connected, control vehicle stability based on the trailer being connected.

Abstract
Method and apparatus are disclosed for vehicle trailer detection. An example vehicle includes an accelerometer and an electronic stability control unit. The electronic stability control unit (a) detects, with the accelerometer, signals indicative of axles traversing a bump (b) when at least three axle signals are detected, generates an axle profile based on a speed of the vehicle and timing of the signals, (c) based on the axle profile, determines whether a trailer is connected to the vehicle, and (d) when the trailer is connected, controls the vehicle stability based on the trailer being connected.
