Abstract:
A system functionally testing an automotive engine management system (EMS), prior to installation in an automobile comprising:(a) means for generating a series of EMS input signals which are equivalent to input signals generated by an automobile;(b) means for applying the EMS input signals to the EMS in a manner which simulates that of the inputs from an automobile;(c) a series of loads connected to outputs from the EMS, the loads being electronically equivalent to the loads imposed by systems within an automobile under control of the EMS;(d) sensors for measuring the EMS outputs;(e) means for coordinating, in real time, application of the EMS inputs and measurement of EMS outputs in parallel comprising an embedded controller with a real time operating system;(f) a VXI backplane for the various functional elements of the system; and(g) means for analyzing the measured output signals to assess EMS function.
