车上不太会坏的ACC，为啥每年都会“失灵”？

Core Viewpoint - The article discusses a recent incident involving a car with malfunctioning adaptive cruise control (ACC) and brakes, emphasizing the reliability of modern automotive systems and the importance of driver knowledge in emergency situations [1][3][19]. Group 1: Incident Overview - A driver experienced a failure of both the adaptive cruise control and brakes while driving a gasoline-powered car at high speed, resulting in a 490 km journey before the vehicle ran out of fuel [3]. - Emergency services effectively managed the situation, ensuring no accidents or injuries occurred during the incident [3]. Group 2: System Reliability - The ACC system, while potentially malfunctioning, is designed with multiple safety checks and redundancies, making complete failure highly unlikely [8][10]. - The ACC monitors over 30 vehicle and driver parameters, ensuring that it disengages under unsafe conditions, such as when the driver applies the brakes or shifts gears [9][10]. Group 3: Driver Response - In the event of a loss of control, drivers can safely stop a gasoline vehicle by disengaging the engine from the transmission or applying the brakes forcefully [16][18]. - Historical incidents of alleged brake failure often stem from driver error or external factors rather than actual vehicle malfunctions [19][21]. Group 4: Market Insights - The adoption rate of ACC in new vehicles has reached 57.5%, with a higher rate of 71.6% in electric vehicles, indicating a growing reliance on this technology in the automotive market [12].
