The working principle of the car engine indicator light?
Usually, the relationship between vehicle speed and throttle opening when the car is running on a flat road is stored in the ROM of the cruise control system ECU. The cruise control system automatically maintains the car at a constant speed according to the target speed.
When the car is cruising at a constant speed when the car speed drops, the ECU increases the throttle opening to increase the engine power and torque, and the car speed reaches the set speed. Conversely, reduce the throttle opening.
When the vehicle speed is below 40 km/h and above 160 km/h, the cruise system does not work. Of course, the upper and lower limits are slightly different depending on the model.
If the control line is made to be in a vertical state, the speed fluctuation (control error) is reduced to zero. In this way, small changes in driving resistance will cause changes in the throttle opening. Due to the excessive sensitivity of the response, it is easy to cause running. Therefore, it is necessary to comprehensively consider the control error and the problem of traveling, and select the appropriate control line slope.
Once the sensor of the system fails, or the control signal circuit is cut off because there is no vehicle speed signal, the low-speed limit circuit will consider the vehicle speed to be zero and stop the cruise control system.
What color can the car engine indicator light be?
Car engine indicator light There are five regular colors of red, yellow, blue, green, and white. If customers need special colors, we can also customize them.
What voltes can the car engine indicator light be?
Indicator light the voltage can be 3V 6V 12V 24V 110V 220V 380V and so on.
Indicator lights the warranty period of the indicator lamp is 5 years. If FILN Car engine indicator light has quality problems or damage during its use within 5 years, FILN company promises to replace Car engine indicator light free of charge.
What certification does Car engine indicator light have?
FILN LED engine indicator light has obtained many international certifications, including UL certification in the United States, VED certification in Germany, CE certification in the European Union, ROSH certification, etc., and it has also obtained ISO9001 quality management system certification.
How to distinguish a good car engine indicator light?
- Whether the material of the car engine indicator light (especially LED) and resistance are used properly, if the quality and resistance of the car engine indicator light are not good, the car engine indicator light will be bad. When designing the indicator light, it will test the withstand voltage of the indicator light. The performance of temperature, life, method, and other aspects ensure the stability of the index quality.
- Whether the production process of car engine indicator light is consistent depends on the experience and professional level of the car engine indicator light factory. When the conventional car engine indicator light factory produces a new car engine indicator light, it will first make a process flow chart and display the lighting process card, indicator light work instructions, and indicator light inspection.
