During vehicle operation, noises such as engine noise, tire road noise, and wind noise can greatly affect the in-cabin entertainment experience and also cause driver fatigue, impacting safety. Traditional NVH (Noise, Vibration, and Harshness) technology uses material soundproofing to isolate noise, but this significantly increases cost and vehicle weight. RNC (Road Noise Cancellation) active road noise cancellation technology captures road noise reference signals through sensors or microphones, and through DSP (Digital Signal Processing) high-performance computing, generates an anti-phase source to cancel out the in-vehicle noise, thereby improving the driving experience and ride comfort. EOC (Engine Order Cancellation) engine noise control technology models the order noise of the engine or range extender engine, generates a cancellation signal, and reduces engine noise.
