Abstract
An apparatus on an integrated circuit provides a real-time flexible interface between inputs from a vehicle components and outputs to the vehicle control components. The functions comprises of a programmable interconnection matrix, engine sensors and a control interface. Both engine sensors and control functions comprise of fixed hardwired functions and a customization hardware area. The apparatus therefore provides means for flexible powertrain events control target for the next generation of low-polluting power trains of vehicles.
