TRAILER SWAY CONTROL WITH REVERSE SENSORS
First Claim
Patent Images
1. A method of trailer sway control, comprising:
- the steps of;
taking proximity sensor readings to sense proximity between a trailer and a towing vehicle that is towing the trailer;
sensing a turning of a steering wheel of the towing vehicle to provide steering wheel turn readings; and
braking to counter trailer sway in a manner that furthers stabilization by taking into account the proximity sensor readings and the steering wheel turn readings.

Abstract
Reverse proximity sensors are used to determine an angle between a towed trailer and the towing vehicle. The trailer sway control determines a trailer angle of sway based upon proximity sensor readings from the reverse proximity sensors and from a sensor reading of an angle of turn of a steering wheel of the towing vehicle. Provided the determined trailer angle of sway exceeds a range that can be tolerated, a controller sends instructions to apply necessary braking to the vehicle or trailer to mitigate the trailer sway.

14. An apparatus suited for trailer sway control, comprising:
-
at least one proximity sensor configured and arranged to sense proximity between a trailer and a towing vehicle that tows the trailer so as to provide proximity sensor readings; at least one detector arranged to sense a turning of a steering wheel of the towing vehicle to provide steering wheel turn readings; and a trailer sway control system configured to direct braking to counter trailer sway in a manner that furthers stabilization by taking into account the proximity sensor readings and the steering wheel turn readings. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
