Abstract
A system for a vehicle and a trailer connected to the vehicle is provided. The system includes a trailer brake output circuit configured to output a trailer brake output signal, and an electronic control unit. The electronic control unit is configured to determine whether a value of a yaw rate of the trailer connected to the vehicle becomes greater than a threshold value, change a yaw rate oscillation counter in response to determining that the value of the yaw rate of the trailer becomes greater than the threshold value, instruct the trailer brake output circuit to output the trailer brake output signal to the trailer in response to the yaw rate oscillation becoming a first value, and activate trailer sway control in response to the yaw rate oscillation becoming a second value. The second value is greater than the first value.
