Relevant Knowledge

The instrument panel is an interactive interface between humans and cars, providing drivers with the necessary information such as car operating parameters, faults, mileage, etc. It is an essential component of every car.

The intuitive and beautiful display of the instrument panel not only makes driving a necessity for transportation, but also a part of comfortable life. The accuracy and reliability of parameter transmission are directly related to the safety of car driving.

Provide the driver with the required vehicle operating parameters, faults, mileage, and other information. The dashboard of a car is a device that reflects the working conditions of various systems in the vehicle. Common ones include fuel indicator light, cleaning fluid indicator light, electronic throttle indicator light, front and rear fog light indicator light, and alarm light.

The following is the relevant content of instrument lights:

1. Indicator lights: The most common indicator lights for driving, such as light signals, turn signals, parking lights, etc., are used to indicate the status of various functions of the vehicle;

2. Warning light: With warning functions, such as fuel indicator light, door status indicator light, seat belt indicator light, etc. The general warning light goes out after the driver takes corresponding actions, such as the seat belt indicator light. When we fasten the seat belt, the seat belt indicator light will go out;

3. Fault indicator light: It is also the most important indicator light, such as generator fault indicator light, gearbox fault indicator light, etc. These fault indicator lights rarely light up in normal times, or when starting the engine, they will light up for a moment and then go out. If the fault indicator light remains on and accompanied by a warning sound, it indicates that the vehicle has experienced a malfunction or abnormality.

The most prominent feature of modern instruments is the modularization of functions. Usually, a single instrument needs to be assembled, and only a few functional modules need to be combined on the basis of customized PCBs to obtain a complete system. The pointer instruments of Chang'an and other economic vehicles are generally independent modules, and the indication/alarm function is completed by a small light bulb on the PCB. The SANTANA series pointer is driven by a cross coil on the printed circuit board, Reminder/alarm lights are all the main data, sources, and corresponding display methods displayed on the dashboard of light-emitting diodes cars.

Display method

It can be seen that automotive instruments are still mainly mechanical, while communication methods are mainly wire harnesses. The biggest drawback of this model is its excessive reliance on wire harnesses, which leads to complex systems. With the rapid development of the automotive industry, the automotive electronics market with great potential is increasingly receiving attention from major automotive manufacturers and electronic product suppliers, including clean energy vehicles that are still in the development and experimental stage The advantage of using electronic instrument panels over traditional instruments for automotive instruments, such as in car computer information terminal devices and various in car electronic control units, such as engine electronic control units, ABS, buses, and new electronic instruments, is that the use of electronic instrument panels, which occupy the world market leader position in Japan, is the software based hardware functions.

With the development of microelectronics technology, the processing speed of microprocessors is becoming faster and higher, with high real-time requirements. The functions originally completed by hardware can be achieved by programming microprocessors.
