The purpose of my work was the functional development of a video-based adaptive tempomat with the tools ensured by Robert Bosch Ltd. As a result of this, the completed software was expected to be capable of faultless transmission on the CAN communication network of a test car. Within the scope of this work, the most common modern driver assistance systems were reviewed, with special emphasis on the variants of the adaptive tempomat according to sensors and functionality. The requirements of the automotive software development and the most important related standards and practices were also presented.

After detailing the software and hardware parts existing initially, the problems coming from the CAN communication structure and the operation of the test car were revealed with the possible solutions. Following the regulation of the communication and the implementation of the first operable software, the planning and development steps leading to the second, final goal were discussed. Herein the calibration of the sensor and the implementation of a new, AUTOSAR standard compatible component and the creation of its test environment were reviewed. Along this process, the reason for the usage of different software variants and the changes between them was handled with priority.

The finished software was tested in several stages, in real and simulated environments. The tests were then analysed and the possible faults were corrected based on this.
