Patent Images
1. A control system for a vehicle comprising:
- a speed sensor generating a vehicle speed signal;
a sway detection sensor generating an oscillation signal in response to trailer oscillations in a predetermined frequency range for at least a predetermined period of time;
at least one vehicle brake;
a brake control coupled to said at least one vehicle brake and associated with at least one trailer brake;
a stability control system coupled to said speed sensor, said sway detection sensor, and said brake control; and
a controller coupled to said stability control system and braking at least one of said at least one vehicle brake and said at least one trailer brake and in response to said oscillation signal.

Abstract
A control system for a vehicle includes a speed sensor that generates a vehicle speed signal. A sway detection sensor generates an oscillation signal. A brake control is coupled to a vehicle brake and is associated with a trailer brake. A controller is coupled to a stability control system and brakes one or more of the vehicle brake and the trailer brake and in response to the oscillation signal.

20. A control system for a vehicle comprising:
-
a sway detection sensor generating an oscillation signal in response to detecting trailer oscillations within a predetermined frequency range for at least a predetermined period of time; at least one vehicle brake; a brake control coupled to said at least one vehicle brake and associated with at least one trailer brake; a stability control system coupled to said sway detection sensor and said brake control; and a controller coupled to said stability control system and applying a proportionally greater braking force with said at least one trailer brake than said at least one vehicle brake in response to said oscillation signal. - View Dependent Claims (21, 22, 23, 24)

25. A method of controlling a stability control system of a vehicle that is pulling a trailer comprising:
-
generating a vehicle speed signal; generating an oscillation signal indicative of a trailer swaying relative to the vehicle, said oscillation signal being generated on the vehicle only and in response to detecting trailer oscillations within a predetermined frequency range for at least a predetermined period of time; braking at least one trailer brake when said vehicle speed signal is greater than a predetermined speed and in response to said oscillation signal. - View Dependent Claims (26, 27)
