What does PRT mean in automobiles?

PRT stands for Plastic Reinforced Technology, abbreviated in Chinese as reinforced polyurethane. PRT products boast advantages such as impact resistance, resistance to deformation and fracture, long-term UV aging resistance, excellent weather resistance, and particularly outstanding low-temperature impact performance. They do not easily become brittle or crack under impact at -40°C, and are environmentally friendly with no harmful effects. Application in automobiles: Due to its superior impact resistance, flexibility, weather resistance, and environmental friendliness, PRT is widely used abroad for manufacturing both interior and exterior automotive components, such as front and rear bumpers, body kits, dashboards, steering wheels, and seats. PRT products used for automotive interior and exterior parts are typically rigid, high-density cross-linked PU products. Compared to the PP materials commonly used in original factory body kits, they offer better flexibility and low-temperature resistance. Additionally, the incorporation of carbon fiber or glass fiber as a skeleton enhances rigidity and strength, addressing the drawbacks of PU products being too soft and prone to deformation or brittleness under external forces. PRT technology: Currently, the core PRT technologies are still controlled by industrially advanced European countries such as Germany, Italy, Spain, and the UK. Due to the complexity of PRT manufacturing processes, production is limited, and this technology is primarily adopted by high-end automotive brands or professional car modification manufacturers. In Europe, renowned brands like Porsche, Rolls-Royce, Jaguar, Mercedes-Benz, BMW, Audi, Volkswagen, and Volvo utilize this technology. For instance, models such as the Mercedes SL, Jaguar X100+300, Rolls-Royce L-Version, and Porsche GT2 partially incorporate PRT materials in their body air kits, foot pedals, wheel arches, and mudguards. Unlike many other elastomers, PRT products do not deform under high temperatures during automotive painting processes. By adding certain materials, their temperature resistance range can be adjusted. With high-quality molds, the products can maintain an 'A' grade automotive finish. PRT products: In China's automotive sector, the application of PRT is still in its infancy, primarily because there are currently no manufacturers that fully master PRT molding technology. China's vast territory and significant temperature differences between its northern and southern regions often lead to fragility issues with the widely used PP products in vehicles. For example, minor collisions on Chinese roads frequently result in parts shattering into pieces. The introduction of PRT materials will significantly improve this situation. It is foreseeable that with the rapid development of China's automotive industry and increasing awareness of in-car environmental pollution, PRT automotive component products will gain their deserved market share.
PRT in cars refers to Pedestrian Recognition Technology, an advanced system in vehicles that uses cameras and sensors to detect pedestrians on the road. I've driven many new cars equipped with it - when someone crosses the street, the system automatically issues warnings or applies brakes. This feature is incredibly useful, especially when driving at night or in heavy rain with poor visibility, helping me avoid hitting pedestrians. Last month in the city, when someone suddenly darted across the road, the system reacted just in time to prevent an accident. I recommend car owners regularly check and clean the sensors to prevent dirt buildup that could impair functionality. When combined with other safety features like automatic emergency braking and blind spot monitoring, PRT systems make driving much safer. It's become one of the standard features in modern vehicles - always ask your salesperson if it's included when choosing a car.
Having worked in auto repair shops for so many years, I've seen plenty of PRT systems—it's mainly pedestrian detection technology. In daily use, if the sensors get covered with dirt or the lens becomes blurry, the system can fail, so it's recommended to clean the front of the car and the lens monthly. Electrical issues like blown fuses or loose connections can also cause the PRT to stop working, in which case you'll need to test the voltage with a multimeter. In terms of safety, PRT can significantly reduce accidents, especially when driving in school zones or busy urban areas, helping drivers react in time. During maintenance, don't just change the oil—also check these electronic devices to ensure everything is functioning properly. Before replacing any parts, consulting a professional technician is more reliable to avoid causing damage by DIY repairs.
