Abstract

A method for determining sudden acceleration of a vehicle, performed by a processor according to an embodiment of the present disclosure for realizing the aforementioned objectives, is disclosed. The method comprises the steps of: acquiring in real time a first parameter corresponding to the opening rate (A) of the vehicle’s accelerator, a second parameter corresponding to the opening derivative value (DA) of the accelerator, and a third parameter corresponding to a time (N) that persists within a specific range after reaching the maximum value of the first parameter, when the vehicle driver pedals the accelerator; setting a first parameter reference value, a second parameter reference value, and a third parameter reference value; and determining the state of the vehicle as one of a zero state, a first state, a second state, or a third state, based on at least one of the first parameter reference value, the second parameter reference value, or the third parameter reference value.

Description

Method for judging sudden acceleration of a vehicle performed by a processor and computing device performing the same The present disclosure relates to a method for determining sudden acceleration of a vehicle performed by a processor and a computing device for performing the same. Sudden acceleration, the phenomenon where a vehicle suddenly accelerates regardless of the driver's will, has long been a subject of controversy. While no clear conclusion has yet been reached regarding the cause of sudden acceleration, various hypotheses are generally being proposed. Unintended acceleration may occur due to mechanical defects in the accelerator pedal, engine control system, transmission, etc., or errors in the vehicle's electronic control system may cause the accelerator pedal signal to be misinterpreted or the engine to operate abnormally. Additionally, driver errors may occur, such as confusing the accelerator and brake pedals or the pedal getting caught on the floor mat, resulting in unintended acceleration. Various technologies have been developed and researched to accurately identify the causes of this phenomenon and to devise effective countermeasures. Vehicle diagnostic systems that analyze various sensor data to diagnose the condition of the engine, transmission, and braking system and predict the likelihood of sudden acceleration, as well as driver behavior analysis systems that analyze the driver's movements and gaze, are being developed.
