A method and system for providing maximum trailer braking during a high pressure demand, such as during autonomous emergency braking (AEB), for tractor-trailers is provided. The system can include a brake controller of the trailer that uses only tractor anti-lock brake system (ABS) data from the tractor wheels, without using any trailer ABS information, to estimate the surface friction and generate a high or low pressure command to be sent to the trailer based on only the tractor ABS data. The estimation of surface friction may be accomplished using the ABS information from the tractor and the pressure being demanded to determine a percent reduction of pressure requested by the tractor that may be compared to a threshold percentage to differentiate between high and low mu surfaces in real time.

An embodiment vehicle includes a transmission configured to set a travel direction of the vehicle, an indoor camera configured to capture a driver of the vehicle, a cluster configured to display information while the vehicle is in operation, and a main controller configured to, in response to the transmission being shifted to reverse, identify whether a gaze of the driver captured by the indoor camera is directed to a rear of the vehicle and, in response to a determination that the gaze of the driver is not directed to the rear, control to display a warning message.
