A system and method for determining the speed and direction of rotation of a wheel in a vehicle are provided. The system includes a tone wheel configured for rotation with the vehicle wheel and a wheel speed sensor facing the tone wheel. The sensor generates different pluralities of phase-shifted signals responsive to rotation of the tone wheel depending on the direction of rotation of the vehicle wheel. A controller receives one of the pluralities of phase-shifted signals from the sensor, receives a direction signal indicative of the direction of rotation of the vehicle wheel from a source other than the sensor, and associates the plurality of phase-shifted signals with the direction of rotation of the vehicle wheel indicated by the direction signal in a memory.

A braking controller and method in a towing vehicle towing one or more towed vehicles as a combination vehicle provides brake control of the one or more towed vehicles based on a level of braking force applied to the towing vehicle. A non-enhanced braking mode applies a first level of braking force to the towed vehicles in a predetermined reduced proportion relative to the level of braking force applied to the towing vehicle, and an enhanced braking mode applies a second level of braking force to the towed vehicles greater than the first level of braking force. The enhanced braking mode strategy is used unless trailer capability information reported by one or more the trailers fails to match against expected trailer capability information.
