Abstract
An electronic control unit (ECU) is coupled to a vehicle network, such as a controller area network (CAN), which network can be either encrypted or non-encrypted. The ECU includes input and output ports (at least one) which provides a non-encrypted access into the vehicle network. The electronic control unit, also referred to as a specialized ECU or as an enhanced gateway module, in one embodiment includes at least one port for configuring the ECU through a personal computer or other computing device. The ECU in one embodiment includes multiple input/output ports which can interface with vehicle subsystems either through or separate from the CAN. The ECU, in one embodiment, includes a non-encrypted serial data port which allows for communication between the ECU and subsystems provided by a third-party for interfacing into an OEM vehicle network, and especially an encrypted network.
