BME Formula Racing Team participate in the internathional Formula Student competiton since 2007. Teams from different countries compete with each other by building a race car. It is useful for the car developer team to make a lap time measurement system. In this document, I present the construction of a system.

In the first section, I give an overview of the professional lap time measurement systems aviable on the market. Later I examine the principle of the suitable sensors to detect the pass over of the car. I explain how I chose the sensors, which problems come up, and the solutions of the problems. Afterwards, I present the hardware compontents: the microcontroller, the radio and the display module.

Later, I deal with with the softwave architecture. I demonstrate the functionality of the software modules. I present the principles of the embedded operations system which I chose for the software modules integration.

At the final section I give an overview of the achived results, and what can be inproved in the future.
