The Design and Implementation of Start Stop System with Multi-Protocol in Automotive Smart Key System

The researches on the start stop system, which stops the engine on idle, have been briskly carried out around the automobile makers before the appearance of the alternative energy along with the growing needs for the low energy consumption technology and the strengthening vehicle environmental regulations. In addition, the automobile makers are trying to make the start stop system general and encourage purchasing by combining the system to the popular smart key system to not only provide the convenience but reduce the energy consumption as well. In this paper, we designed and implemented the start stop system with multi-protocol that is capable of providing both an eco-friendly start stop system and a convenient smart key system on a single electronic control unit. For performance evaluation, we gathered the necessary data with a software tool for monitoring the vehicle’s network, installed the proposed system on a real vehicle, measured the calculated worst case response time of the multi-protocol on the idle state control module, and compared the results with the benchmark data from the society of automotive engineers. The results show that the proposed system satisfies every time restriction that is related with the proposed system.
