Core Points - Xiaomi Automotive Technology Co., Ltd. has recently published a patent for a "vehicle overspeed alert method, device, vehicle, storage medium, and program product" aimed at enhancing driving safety [1] - The patent involves using sensors to collect information about objects in the vehicle's environment and determining the relative speed of the vehicle compared to these reference objects [1] - The Ministry of Public Security has drafted a national standard plan focusing on safety conditions for motor vehicle operation, addressing issues related to rapid acceleration in new energy vehicles [1] Summary by Category Patent Development - The newly published patent by Xiaomi involves technology that alerts drivers when they exceed a preset speed threshold, thereby improving road safety [1] - The system utilizes sensors to gather environmental data and assess the vehicle's speed relative to other objects [1] Regulatory Changes - The draft national standard plan includes new technical requirements for passenger vehicles, mandating that vehicles should default to a state where the acceleration time to 100 km/h is no less than 5 seconds after each ignition [1] - It also requires electric and plug-in hybrid vehicles to have a pedal misapplication acceleration suppression feature, which detects and mitigates unintended acceleration while providing clear signals to the driver [1]

Core Viewpoint - The report highlights significant rainfall and severe weather conditions affecting various regions in China, leading to potential hazards for transportation and travel safety [1][3][4]. Weather Impact on Transportation - Major areas affected by heavy rainfall include western and southern Sichuan Basin, central and western Yunnan, southern Shaanxi, eastern and southern Shanxi, northern and western Henan, central and southern Hebei, northeastern Shandong, central and southeastern Liaoning, southeastern Jilin, most of Hainan Island, southwestern Guangdong, and southern Guangxi [1]. - Specific highways and routes impacted by heavy rain include G2, G3, G4, G5, G1113, and G1212, with localized severe weather warnings issued for these areas [3][4][5]. Safety Recommendations - Drivers are advised to monitor weather updates and road conditions, especially in areas prone to landslides and flooding, and to avoid high-risk zones [1]. - In adverse weather, it is crucial to reduce speed, avoid sudden maneuvers, and maintain a safe distance from other vehicles to prevent accidents [7][8][10][12]. - It is recommended to avoid using high beams and hazard lights in rain, and to use appropriate lighting based on visibility conditions [14]. - Planning routes to avoid low-lying areas and flooded roads is essential, and caution should be exercised when encountering water on the road [15].

Core Points - A BYD Song PLUS EV was struck by lightning three times during a thunderstorm in Beihai, Guangxi, but the female driver remained unharmed and continued her journey as planned [1] - The core components of the vehicle, including the battery, motor, and electronic control, were reported to be intact after the incident [3] - The vehicle's exterior showed no significant damage apart from two burn marks on the roof, and it was confirmed that there were no short circuit signs in the main components [5][8] - The incident highlighted BYD's commitment to safety, reinforcing the idea that electric vehicles can provide protection during thunderstorms [10]
