What's the buzz of Buick Angkor driving?

On the other hand, Buick Angkewei vehicles are equipped with low-speed collision avoidance system (LSCMB). If it is detected that the vehicle or obstacle in front meets the function trigger conditions mainly for speed and distance comparison during driving, EBCM sends an instruction to the module motor to start the motor and brake according to the response of the valve body. At this time, you may hear the sound of module motor starting and brake fluid flowing. Angkor's high-profile models are equipped with full-speed adaptive cruise system (FSACC), which will adjust its speed according to the vehicle speed and distance during operation. First, use the engine throttle to adjust the speed. If the throttle is not adjusted in time, the electrically adjustable movable module may intervene, resulting in noise. At the same time, Angkor also uses ANC active noise reduction technology to monitor the engine noise actually felt by passengers through three microphones in the car. According to its waveform characteristics, the inverse waveform is calculated by the processing chip, and the inverse sound wave is emitted by the high reduction speaker and cancelled, so as to achieve the comfort of the vehicle. However, when the engine switches between low speed and gear, there will be a rumbling sound of exhaust gas flow. Due to the engine calibration, the airflow with fluctuating exhaust gas output will collide with the muffler bag of the exhaust pipe, resulting in * * * vibration and noise. This kind of sound appears in a specific rotation range and situation, which has a certain impact on driving comfort. To sum up, Buick Angkewei has adopted various technical means to reduce the noise inside the car, but there will still be some noise under certain circumstances.
