Automotive PCBs: The Unsung Heroes Behind Safety and Comfort

In modern vehicles, automotive PCBs are everywhere. They not only support the operation and safety of the vehicle but also bring comfort and intelligent experiences to drivers and passengers. Whether in traditional fuel vehicles or today’s new energy and smart cars, automotive PCBs remain the fundamental backbone of electronics.

As a trusted automotive PCB manufacturing and assembly service provider, HOYOGO has been deeply engaged in the automotive field for many years, offering professional and reliable circuit board products to global automakers. Let’s take a closer look at the value of automotive PCBs in different vehicle systems.

1. Power Control Devices

In power control equipment, automotive PCBs play a crucial role. For battery management, the PCB acts as a precise connection hub, providing a stable connection platform for parameter acquisition circuits and charge/discharge control circuits. Key parameters such as battery voltage, current, and temperature are collected by sensors, then accurately transmitted via PCB circuits to the control chip. After processing, the control chip sends charging and discharging commands through PCB circuits to the actuators, ensuring precise control of the battery state and preventing overcharging or over-discharging.

At the same time, PCBs also support the smooth operation of motor drive control equipment, ensuring the stable and reliable transmission of signals related to motor speed and torque. This allows precise power regulation, guaranteeing the overall stability of the power system.

2. Safety Systems

The effective operation of safety systems also relies on automotive PCBs. In ABS devices, signals collected by the wheel speed sensors are quickly transmitted through PCB circuits to the control unit. The unit then processes the data and sends braking commands via the PCB to the actuators, enabling timely adjustment of braking pressure and effectively preventing wheel lockup.

In ESP devices, PCBs aggregate information from multiple sensors, such as body acceleration and steering angle. With PCB support, this information is accurately transmitted to the control chip, which analyzes the data and issues intervention commands through the PCB to maintain vehicle stability.

For airbag control systems, collision signals are instantly transmitted through PCBs, ensuring airbags deploy at the critical moment to protect passengers.

3. Intelligent Driving Systems

In intelligent driving systems, domain controllers for autonomous driving are built on automotive PCBs. They enable efficient transmission of data from multiple sensors, including millimeter-wave radar, LiDAR, and cameras, while also providing a stable operating platform for high-performance processors. This ensures the rapid computation of massive datasets, supporting advanced functions such as adaptive cruise control and automatic emergency braking.

4. Infotainment and Body Electronics

In infotainment and body electronics, automotive PCBs support the processing and transmission of various signals, such as images, audio, navigation, allowing passengers to enjoy high-definition video, quality music, and accurate navigation. For control devices like lighting and power windows, PCBs serve as the carrier for command transmission and action control, ensuring precise and convenient operation such as light switching and window lifting, thereby enhancing overall driving comfort.
