Abstract

Modern vehicles use onboard computers to control driving systems, including braking and airbag deployment. The computers are connected to sensors throughout the vehicle and send the sensor data to EDR (Event Data Recorder aka Vehicle Black Box). But these EDRs have limitation, such as this EDR itself went wrong during the crash event. As a result the data that was stored is not good enough to figure out whether the car or the driver is to blame. Some of the stand-alone Digital Video/Audio Recorders that are currently in the market are used primarily for security purpose and thus are not going to help to analyze a crash event. The aim of this project is to design a next generation Vehicle Black Box (EDR), named as E-Crashcorder (Enhanced Crash Data Recorder).E-crashcorder records the value of accelerator pedal position, brake pedal position, steering wheel angle, crash severity, vehicle direction, wheel speed, transmission gear position, airbag deployment data, audio and video snapshot, when there is a change in 3-Axis MEMS Accelerometer. This data is used to find the actual accelerator and brake level applied by the driver, angle of steering wheel, direction and speed of the vehicle, vehicle status and location of the vehicle during the crash. These values are used for crash investigation.
