Automotive relay plays a vital role in automotive circuits. It is an "automatic switch" that uses small current to control large current. It is mainly responsible for functions such as automatic adjustment, safety protection, circuit conversion and control. Specifically, the relay controls the on and off of the device through its contacts, which can realize the on and off control of the circuit, thereby ensuring the normal operation of the automotive circuit. At the same time, the relay itself has a protection function, which can effectively protect the automotive circuit.
2. Specific application in automated driving assistance system
Circuit control and protection: In automated driving assistance system, automotive PCB relay is responsible for controlling the on and off of the circuits of various sensors, controllers and actuators. When the system requires a certain device to work, the relay closes the contacts to allow current to pass through the device; when the system does not require the device to work, the relay opens the contacts to cut off the current, thereby protecting the device from damage. Relays also have overload and short-circuit protection functions. When the current exceeds the set threshold, the relay automatically opens and closes the circuit, thereby protecting the main components of the electrical system from damage due to overload and short circuit.
Signal amplification and transmission: In the automatic driving assistance system, the signals collected by the sensor are often weak and need to be amplified before they can be recognized and processed by the processor. The relay can amplify these low-power signals to a sufficiently high current to drive the corresponding device, thereby ensuring the accurate transmission and processing of the signal.
Realize complex circuit conversion and control: The automatic driving assistance system involves multiple complex circuits and control logic. By combining multiple relays, complex circuit conversion and control can be achieved to meet the system's needs for different working conditions and scenarios.
3. Improve the performance and safety of the automatic driving assistance system
Improve system reliability: The automotive PCB relay has the characteristics of high reliability and long life, and can operate stably in harsh automotive environments. This helps to improve the overall reliability of the automatic driving assistance system and reduce system failures and maintenance costs.
Enhance system safety: The role of relays in circuit control and protection helps prevent safety accidents caused by electrical system failures. At the same time, by precisely controlling the on and off of the circuits of each device, the relay can also ensure that the autonomous driving assistance system can respond quickly and take measures in an emergency to ensure the safety of the driver and passengers.
In summary, the automotive PCB relay plays multiple roles in the autonomous driving assistance system, including circuit control and protection, signal amplification and transmission, and realization of complex circuit conversion and control. These roles jointly improve the performance and safety of the autonomous driving assistance system and provide strong support for the development of intelligent driving technology.
