Immobilizer Engine Control Unit (ECU) Using Radio Frequency Module

Automotive applications are increasingly influenced by the safety requirement. Yet their complexity and costs should not increase. Thus, this paper introduces the conceptual understanding and strategy of Radio Frequency Module application to be deployed in vehicle security system. Due to that, an Immobilizer Engine Control Unit (ECU) using Radio Frequency Module application innovated that utilizes the uses of microcontroller to provide the safety functions in any vehicle. This system analyzes the input receive at the Radio Frequency receiver from Radio Frequency transmitter to connect the power supply to the engine ignition part before cranking the starter motor. The wireless characteristics of Radio Frequency Module enhance the system to be unreachable by the vehicle thieves and where cost are not more being a problem to the community upon their vehicle safety.
