This study analyzes the automotive behavior and its impact on driving safety when the Micro controller Unit (Micom), a core component of the automotive Engine Control Unit (ECU), is exposed to high temperatures. The automotive behavior was observed with and without the ECU housing cover under thermal exposure, and the temperature of the Micom was determined using heat transfer principles. The results showed that with the housing cover in place, a thermal equilibrium was maintained at approximately 160[°C], and the Micom's temperature was about 73[°C], which is within its guaranteed operating limits and did not affect the automotive behavior. When the housing cover was removed, the engine stoped to operate at approximately 220[°C], and it is presumed that the Micom's internal circuitry was damaged. These findings can provide useful quantitative data for future reliability assessments of ECUs and for investigations into sudden unintended acceleration phenomena.
