초록

This study investigates the effects of various Throttle Position Sensor (TPS) signal anomalies and throttle body defects on automotive acceleration and safety by experimentally reproducing and analyzing eight distinct fault scenarios. The results demonstrate that the Electronic Control Unit (ECU) consistently detects signal anomalies and activates fail-safe modes, limiting throttle response and engine output to maintain automotive control. In all fault conditions, sudden unintended acceleration was effectively prevented, and braking performance remained unaffected. These findings underscore the robustness of the throttle control system against electrical and mechanical defects and offer valuable insights for the design of safer drive-by-wire systems.
