The Application of RFID in the Automotive Market

The application of RFID (Radio Frequency Identification) technology in the automotive market has covered the entire industry chain, playing an important role from production and manufacturing to terminal management. The following are the main application scenarios and technical features:

1、 Production and manufacturing process

1. Vehicle tracking and process optimization

In welding, painting and other processes, each vehicle is embedded with high temperature resistant and corrosion-resistant RFID tags. Real time vehicle data is obtained through a reader, and process parameters (such as welding strength and coating thickness) are automatically called to avoid quality problems such as color mixing. SAIC Audi Intelligent Manufacturing Base adopts RFID tags to achieve fully automatic process control, with 60 scanning points to ensure traceability of production data.

2. Component management

RFID technology is used to track the location of components on the production line, improve assembly efficiency, and reduce manual inventory errors.

2、 Logistics and sales process

1. Vehicle transportation tracking

In logistics, RFID tags locate transport vehicles in real-time, optimize route planning, and monitor the status of goods.

2. Inventory and Customer Management

The sales process utilizes RFID to achieve automated management of vehicle inventory and supports efficient scheduling of customer appointment services.

3、 Terminal vehicle management

1. Smart key system

The keyless entry system using RFID technology automatically unlocks when the owner approaches the vehicle, and when starting, the smart card is detected and recognized inside the car, without the need for a physical key (such as a Tesla RFID induction card).

2. Tire lifecycle management

Tire RFID tags record production, usage, refurbishment, and other data, achieving full cycle traceability and solving the problem of traditional labeling being prone to wear and tear.

3. Electronic toll collection and traffic management

Windshield or car light tags are used for ETC and automatic toll collection in parking lots, supporting seamless high-speed passage (RFID technology). Car light labels can avoid interference from windshield film and improve recognition stability.

4、 Innovative applications

Modular vehicle recycling: Composite electric vehicles embedded with RFID tags optimize the disassembly process through digital twin technology, increasing recycling efficiency by more than 70% compared to traditional processes.

Supply chain finance: Anti tamper RFID tags are used for asset tracking to reduce financial risks.

RFID technology significantly improves the efficiency and intelligence level of the automotive industry through non-contact data collection, and has enormous potential in the fields of vehicle networking, smart transportation, and more in the future.
