Here, RenhotecIC will tell you about improving vehicle noise through active noise reduction, thereby improving vehicle safety and driving experience.

　　First Road Noise Elimination Product in New Sensor Series.It has been proved that the product can reduce noise, weight and cost.

　　The design period is shortened, the sensor can be installed flexibly, and the engineering design is simplified.

　　Cooperation to Promote the Construction of Automobile Ecosystem.


　　Road noise reduction (RNC) sensor based on accelerometer is the first product in the new series of vehicle active noise reduction (ANC) sensors. These sensors will play a key role in noise reduction and can help eliminate harmful road noise, wind noise and automotive HVAC noise, as well as low frequency sound, thereby reducing driving fatigue.

　　Advances in electronics have enabled ANC technology to change the way carmakers respond to traffic noise. ANC is usually used for high-end headset noise reduction. ANC sensors do not need to install expensive and bulky sound-absorbing materials to protect the interior from excessive driving noise. Design, the ANC sensor is installed on the chassis of the car to obtain more accurate and effective data. But the equipment installed on the wheel cabin and frame must be able to adapt to the worst environment.

　　With the rapid transition to electrified vehicles, reducing road noise will become crucial, and now road noise has been masked by internal combustion engine noise. With the rapid transition to electrified vehicles, reducing road noise will become crucial, and now road noise has been masked by internal combustion engine noise.

　　Electrification, connection and sensor technology in the automotive field are among the most important innovations. How to run electronic devices and software in extreme cases is an obstacle to innovation.

　　Excellent performance in harsh conditions

　　Ensure that high fidelity audio signals are provided while significantly reducing wiring complexity, cost, and weight. the noise signal is transmitted to the processing unit in less than two milliseconds by Molex the sensor with the A2B network. The sensor includes integrated connectors and chrysanthemum chains that simplify integration and reduce cable weight (up to 30% reduction in weight).Safer, more optimized driving experience

　　The combination of hardware and software in a wide frequency band (from 20 Hz to 1 kHz) can eliminate up to 90% of the harmful noise and improve the comfort, safety and happiness of the passengers. In particular, the buzzing noise between the road and the tire is eliminated, and the hypnotic effect and driver fatigue effect are significantly reduced.

　　Experience is essential

　　Network connectivity has a long history and has gained a long reputation in terms of product quality and customer collaboration to meet the growing demands of consumers on the entire automotive ecosystem, which involves electrification, advanced driver assistance systems (ADAS), automotive high-speed networks, vehicle antenna systems, Zhaopin automotive solutions, and vehicle-to-external communications (V2X).
