    摘要： A method of authenticating an automotive device connected to an engine control system that stores an authentication code in memory of the automotive device that is generated by an encryption algorithm using an identification code of the automotive device as a seed value. The engine controller determines a verification code using a complementary encryption algorithm that also uses the identification code received from the automotive device as a seed value. The engine controller compares the authentication code to the verification code, and indicates that the automotive device is not authentic if the authentication code does not correspond to the verification code. Advantageously, authenticating the automotive device will be done autonomously by the engine controller without prompting by a technician using special equipment such as a laptop computer.

    摘要： A method/system for measuring cylinder pressures of an internal combustion engine includes a crank angle sensor utilized to generate pressure readings at known angular intervals. Additional time-based pressure measurements are taken in selected angular windows between a pair of the angle-based pressure readings. Because the angle-based pressure measurements and the time-based pressure measurements occur at known times, the pressure as a function of the crank angle for the time-based pressure measurements can be determined. The cylinder pressure measurements can be utilized to calculate combustion parameters used for closed-loop engine control of fuel supply or other engine inputs.
