What are the applications of automotive relays in safety systems?

The application of automotive relays in safety systems mainly includes the following aspects:

Anti-lock braking system (ABS): Automotive relays play a key role in the ABS. By controlling the distribution and pressure regulation of brake fluid, they ensure that the vehicle can remain stable during emergency braking, prevent wheel locking, and improve braking effect and driving safety.

Battery short circuit protection device: The relay can sense abnormal conditions in the circuit, such as short circuit or overload, and cut off the circuit when necessary to protect the battery and other electrical components from damage, ensuring the stable operation of the vehicle's electrical system.

Control of turn signals and indicator lights: The relay is used to control the switch of turn signals and indicator lights to ensure that the relevant indicator lights can light up accurately and timely when the vehicle turns or uses lights, improving driving safety.

Safety guarantee in emergencies: In emergencies, the relay can quickly cut off the fuel supply or other key circuits to prevent accidents such as fire and ensure the safety of vehicles and personnel.

Mechanism of action of relays in safety systems:

Automatic control: The relay controls the opening and closing of contacts through electromagnetic force to ensure accurate current control and prevent overload or short circuits. ‌Safety protection‌: Relays can sense and respond to abnormal situations, cut off circuits in time, and avoid safety accidents such as electrical system damage or fire. ‌Circuit segmentation management‌: Relays can divide complex electrical systems into multiple parts, control large currents through small currents, simplify circuit management, and improve system stability and reliability. ‌In summary, automotive relays play a vital role in safety systems, ensuring the safe operation of vehicles under various working conditions by precisely controlling and protecting circuits.
