STM32 Microcontroller-Based Voice-Activated Anti-Throttle Mis-Stepping System

Aiming at the problem of drivers mistakenly stepping on the throttle as the brake, this paper summarizes the advantages and shortcomings of the existing related designs and proposes a design scheme for an intelligent control system for automotive throttle mis-stepping without changing the original operation structure. This paper proposes a throttle mis-stepping judgment model, which uses the voice recognition bundle to identify the screaming sound of the car owner, while judging whether the throttle acceleration is greater than the threshold value, so as to determine whether the throttle is mis-stepped. This paper also uses the model to design a throttle mis-stepping hardware system with STM32 microcontroller as the main control, which consists of a voice signal processing module and an execution module, and Bluetooth is used for information transmission between the modules. The hardware system designed in this paper has high real-time and intelligence, which can assist the driver to drive safely and finally achieve the purpose of ensuring driving safety.
