Promoting the Robustness of Calibration-Based Computations

Calibration parameters are extensively used in complex automotive Engine Control Units (ECUs), including ECUs for the engine, transmission, Anti-lock Braking System (ABS), and Electronic Stability Control (ESC). Calibration engineers can set the exact values of calibration parameters for a given software application after the ECU software is built. Such parameters also enable a single set of software to control multiple hardware variants, for example 4-cylinder and 6-cylinder engine variants, or turbo and non-turbo variants. In an ECU, there are often hundreds and sometimes tens of thousands of calibration parameters, some of which are multidimensional tables. With this level of complexity, ensuring that the ECU software using the values from these tables will not encounter an overflow operation, divide by zero condition, or illegal memory access run-time error can be a significant challenge.
