Abstract
A control system for a vehicle that is towing a trailer, the control system including a lateral acceleration sensor coupled to the vehicle for determining a lateral acceleration of the vehicle caused by the trailer swaying and generating a lateral acceleration signal based on the lateral acceleration of the vehicle and a transmission controller for receiving the lateral acceleration signal from the lateral acceleration sensor, comparing the lateral acceleration signal to a threshold, and prohibiting a gear switch signal from being transmitted to a transmission of the vehicle when the lateral acceleration signal exceeds the threshold.
