Prototype design of EDR (event data recorder) on motorcycle

摘要

An Events Data Recorder (EDR) is a unit that record movement parameter of a vehicle mainly used for accident analyzes purposes. Many of EDR has designed for automobile, however they have to be physically connected to sensors integrated with the car's engine and system. That is why it is not easy deploy and very high cost. In this research, we present preliminary design of a simple low cost EDR prototype which utilize only external sensors, i.e. IMU, GPS and Compass information, therefore, this EDR can be banded easily and cheap to be used even on a motorcycle. Some important movement parameters are recorded including geo-position, roll and pitch orientation and velocity. The functionality of this EDR prototype is investigated using a mobile robot and a motorcycle as well under simulation condition. All tested parameters are successfully extracted from the EDR and able to indicate properties of impact in the accident simulation. A 3D GUI is used to animate the motorcycle movements on PC according to the EDR data. This research will be continued in the near future by researching new features such as data compression, security, low energy, signal behavior and also advance testing of this EDR performance and reliability.
