Abstract
A vehicle includes a body structure, a powertrain, a plurality of sensors, a hub unit, a plurality of leads, a powertrain electronic control unit, and a bus. The powertrain is supported by the body structure and includes an engine and a transmission. Each of the sensors is operable for detecting a respective parameter of the powertrain and for generating a corresponding sensor signal. The leads each couple a respective one of the sensors to the hub unit. The bus couples the hub unit to the powertrain electronic control unit. The hub unit is configured to receive the sensor signals from the sensors and, in response to the sensor signals, generate feedback signals and transmit the feedback signals over the bus to the powertrain electronic control unit. A method is also provided.
