In today’s cars, radar and video-based emergency braking systems (AEB) are gaining ground, with the aim of avoiding accidents caused by human inattention. According to researchers, 38% of accidents could be avoided, if all vehicles were equipped with emergency braking systems.
These emergency braking systems are tested by the NCAP. According to the newest protocol (2018 v2.0.1), lateral overlapping tests are required with the accuracy down to 5 cm. This is difficult to achieve relying only on the driver’s eyes.
My job was to design a compact device that can be used to verify the emergency braking systems within the required accuracy even at the development phase.
First I will outline the requirements and then I will present the devices, technologies, and solutions used today. During the design phase, I will present the work I have made based on my decisions. Then I will present the schematic diagrams, the PCB design and the firmware I developed based on an embedded operating system. Furthermore, the controller’s tuning and implementation will be presented too.
