Abstract
A sobriety ignition interlock system including an engine control device and a method for managing available vehicle engine power using the sobriety ignition interlock system. The engine control device includes an engine control processor (ECP) that is electronically connected in between an engine control unit (ECU), an engine sensor assembly, and a sobriety processor. The sobriety processor determines a sobriety level of a vehicle driver and sends a corresponding sobriety signal to the ECP. The ECP intercepts an engine signal transmitted from the engine sensor assembly to the ECU and manipulates the engine signal according to the sobriety signal, in order to manage the available power of the vehicle engine.
Claims17
A method of managing available vehicle engine power, the method comprises the steps of:
- providing a vehicle engine, an engine control processor (ECP), a sobriety processor, an engine control unit (ECU), and an engine sensor assembly;
- calculating, by the sobriety processor, a sobriety level for a vehicle driver;
- comparing, by the sobriety processor, the sobriety level to a sobriety threshold in order to produce a sobriety signal;
- sending, by the sobriety processor, the sobriety signal to the ECP;
- intercepting, by the ECP, an engine signal transmitted from the engine sensor assembly to the ECU;
- manipulating, by the ECP, the engine signal according to the sobriety signal;
- transforming, by the ECP, the engine signal into a modified engine signal, if the sobriety level is above the sobriety threshold;
- sending, by the ECP, the modified engine signal to the ECU;
- and
- retarding, by the ECU, an ignition timing of the vehicle engine in response to the modified engine signal.
