Pre-Crash External Airbag Deployment with Auto-Emergency Braking
- 0 Collaborators
Over the past few decades, there have been many studies proving the advent of airbags that have done wonders to protect cars’ fragile flesh-and-blood cargo when vehicles go smash. A Lot of people especially those who've been protected from injury or death by an airbag deployment must have wondered: What if we put the same technology on the outside of the car? With that vision in mind, we aim at developing a model that will assist the driver and prevent them from any kind of mishap. This project is a idea borrowed from the recent pre-carsh external airbag deployment - a concept by ZF Motors. This system aims at developing a model consisting of a Lidar sensor that will determine distance and control motor speed for immediate anti - braking conditions. Also demonstrate Flex CAN handling capabilities of S32K144 EVB Boards to manipulate the incoming data traffic and thereby control motor speed. ~ IoT Collaboratory Lab, IUPUI https://www.repairerdrivennews.com/2018/12/07/zf-talks-future-of-airbags-including-exterior-side-units/ ...learn more

Overview / Usage
The Logic responds to three test cases;
Case 0 :
Airbag Deployed
This is when crash distance is minimal (about 20 cm).
Case1 :
Automatic Braking will be applied (about a distance of 30 cm)
Case 2 :
Motor will run with its normal speed.
Methodology / Approach
The system thus consists of two S32k144EVB boards (master and slave), a Garmin Lidar Lite V3HP sensor, and a BLDC motor. Lidar will be used to measure the distance and control the rpm of the motor. Here are the steps to be followed – Get the Lidar data from S32k144EVB masters using I2C, process the data and send it over CAN to another S32k144EVB acting as a slave and thus, control the speed of the motor based on the data coming through CAN. We will also deploy sample hardware to showcase airbag activation when the two vehicles reach a certain threshold distance.
