Abstract: Vehicle keyless start control function is one of the comprehensive applications of wireless identification technology and vehicle network technology. Although it improves the safety and convenience of vehicle use, its control signals are complex and diverse. In order to reveal the working principle of the keyless start control system, comply with the sequence action law of digital signals, take the keyless start control system of Mercedes Bens C200 as an example, this paper uses the logic analysis method to fully expatiate “five major” function of the start control system, deeply analyze the transmission path of control signal in vehicle network, gradually unravel the start control logic mechanism, thoroughly rationalize the realization processs of keyless start control function. It not only provides empirical help for automotive electronic product designers to apply keyless start control technology, but also provides a theoretical basis for automotive electronic control technology teaching and experimenters to analyze keyless start control function.
