Coursework 1 : Vehicle safety systems: Radar Based Collision warning

The aim of this Coursework 1 is to study deeply a concrete automotive system. Using as a reference a list of possible topics given, we have chosen the “Radar Based Collision Warning System”.
In this report are included all key factors of this safety system. They are explained during different sections,from economic and performance factors to the impact of this system in the vehicle and where it is located. There is also a little historical introduction in order to put all the information into context and a future view of what is planned for the next years.
Teamwork has been essential in this Coursework 1, combining individual work of each member in the group with group meetings.
