The main task of this work was to design and applicate an electronic brake sys-tem to a hybrid drive racing go-kart.

The eBrake system will complete the original hydraulic brake system on the go-kart, that’s why even if the electronic control unit damages, there will remain one work-ing brake system on our go-kart. The Driver Assistance functions such as Adaptive Cruise Control, Automatic Emergency Braking and Automatic Parking will use the elec-tronic brake system.

The idea and the construction of this brake system come from me and my me-chanical engineer trainee collegue, Szegedi Sándor. We searched the existing automotive solutions and found out if the construction can be implemented to our racing go-kart, naturally with modifications.

I have to design a PCB for the task. The eBrake ECU will communicate with the other ECUs on the go-kart, for that communication we will use the Controller Area Network (CAN). That’s why I need to choose a microcontroller with CAN controller and also solve the power supply of the board. The speed of the CAN will be 500 kbaud and the reference voltage of the microcontroller is 3.3 V.

I have to also solve to measure the speed of the go-kart with some kind of wheel speed sensor.
