Auburn Hills, Michigan – DaimlerChrysler has announced that the all-new 2007 Chrysler Aspen will be in the industry’s first full-size SUV to offer standard trailer sway control technology, which improves trailer stability and increases towing safety.

The system reduces trailer sway (an alternating yaw of the vehicle) and improves handling in adverse towing conditions caused by crosswinds and traffic. Software monitors the vehicle’s movement relative to the driver’s intended path, and the vehicle yaw sensor recognizes sway. Once the system determines the sway is not caused by the driver’s steering input, it applies brake pressure on one front wheel to counteract the yaw induced by the trailer, and applies brake pressure to all four wheels to slow the vehicle. As the trailer sways to the other side, the system will increase pressure to the opposite side of the vehicle. It will continue to apply alternating brake pressure and reduce engine torque until the trailer is under control.

The Aspen is based on the Dodge Durango, which will also offer Trailer Sway Control for model year 2007.
