Design Of The Intelligent Electronic Warning System At Automobile Maintenance

The intelligent electronic early warning system of vehicle maintenance is the use of electronic control technology to detect the vehicle operating conditions and to show the warning and instructions for vehicle maintenance in accordance with the data flow of technical state of vehicles running. This design reflects the contemporary concept which gives emphasis on vehicle maintenance rather than repair.The design for the intelligent electronic early warning system of vehicle maintenance makes use of the self-diagnosis function in the automotive engine electronic control system (ECD) in which the automotive fault diagnostic apparatus is connected to the computer, and dashboards are to be improved into the form of a combination including both the instrument panel of driving and maintenance and computer screen. the technology of the intelligent electronic early warning system of vehicle maintenance is original from the recording function for car failures in the operation in the self-diagnosis system, which can determine the car's maintenance warning according to the range of data stream provided by the automotive fault diagnostic apparatus .The fault warnings will display on the car dashboard or car computer screen in the form of a text shining. The technology can make the computer screen in the ca to display a variety of dynamic datum such as: speed, distance, total mileage, engine rpm, engine temperature, fuel consumption, fuel pressure, oil pressure, oil consumption , parking, ABS, EBD, STOP, VAC (vacuum warning), BAT (battery fluid volume), ST (start), BELT (seat belt alarm display), AC (air conditioning), DOOR (door warning light), Warranty tips, but also can display the technical parameters of the vehicle operating conditions, and provide technical data and maintenance basis for the 4S professional and technical personnel, also can remind drivers of the maintenance projects such as: they should change the oil, clutch oil ,Brake hydraulic oil, hydraulic power steering oil, coolant, replace the air filter, oil filter, fuel filter and so on.Car computer screen can also be developed into ulti-purposes, such as playing a role in navigation connected it with the navigation device, and playing a role in reversing tips connected it with the reversing radar. with the development of the Internet , car computer can be also connected to the Internet, providing early warning maintenance projects for the vehicles with the help of automobile manufacturing technical service center online. To make sure the car life-long trouble-free and avoid to be the overhaul , technically realize the concept that maintenance is more important than repair.A key device of the design for the intelligent electronic early warning system of vehicle maintenance is the cost of the computer of the automotive fault diagnostic apparatus, because the device is a single the decoding system of the vehicle , the cost can be reduced down. Early warning system is mainly maintained by monitoring the car ignition timing , cylinder pressure , the mechanical wear parts, environmentally friendly vehicle indicators, etc., to complete maintenance of the vehicles by the intelligent electronic early warning system.The design for the intelligent electronic early warning system of vehicle maintenance includes both the self-diagnostic system of the vehicle electronic control system and computer failure diagnostic apparatus to read self-diagnostic system .From the point of view of control theory, The technical model are mainly composed of three components , the sensors of the electronic control system, ECU And the actuator. The sensor can be aware of information, which function is to provide automotive ECU and engine operating conditions and other conditions. ECU receives information from the sensors, the processed information issues the appropriate control commands to the actuators. The actuator is the component of implementation, which function is the implementation of special orders from the ECU to complete control purposes.The design for the intelligent electronic early warning system of vehicle maintenance will convey the operating parameters of the engine and power train control systems, automatic speed control system, ABS and traction control system to the car drivers through processing search by electronic early warning system of computer processor (ECU)and displaying on actuator instrument panel ,so that car drivers can make timely and accurate real-time maintenance of the car, making car-free disassembly for life overhaul.
