Abstract
An engine knock control system that can be digitally reconfigured to operate in different knock signal processing modes. The system includes a knock detection circuit that processes an incoming knock signal produced by a vibration or pressure sensor on the engine. The circuit includes a plurality of circuit devices that are capable of being interconnected in different circuit topology configurations to thereby process the knock signal in a selected one of a plurality of different modes. The circuit includes hardware and software for forming a selected interconnection configuration of the circuit devices in response to a coded data signal input to the circuit.
