Improved Embedded Vehicle Safety System With STM32

According to the present situation, road accident is a dangerous threat of our day to day life. We don’t feel safe while travelling because of this dangerous Problem. To confront this issue, we have come up with a real-time vehicle safety system which can reduce the rate of accident using an emergency braking system and also can be used to reduce the problem of traffic jam. The concept of embedded system is used to build the module. An STM32 IC is used along with different sensors like IR Sensor, Sonar Sensor. The sensors detect the presence of obstacles in front of the vehicle and send the sensed value to STM32 IC. According to that, the STM32 IC activates the braking system. A GSM module is also connected to STM32 IC to find the alternative route when the road is highly crowded. We also used arduino instead of STM32 to check the difference in the performance of the module. We observed that the accuracy of braking and object detection system is 100 percent for the device with STM32 whereas that is 60 percent for the device having arduino. There is a noticeable difference in terms of load carrying capacity and the device with STM32 leads in that case also. By doing so we come up with a conclusion that STM32 is better than arduino. A motor driver shield (l293d) is used for both STM32 and arduino to control the motors of the car. For controlling the car, an application named bluetooth rc controller is used for both the module with STM32 and arduino.
