Problems solved by technology
[0003] However, due to natural conditions such as actual road traffic and weather, there will be emergencies, such as earthquakes, heavy rainfall, severe water accumulation in various depressions, mudslides, sandstorms, etc., which will hinder the safe driving of self-driving vehicles. In related technologies, self-driving cars often only It can sense in a limited range, cannot give early warning for emergencies in time, and is not convenient for the adjustment of the follow-up path of the self-driving car, which greatly reduces the safety and reliability of driving

The invention discloses a disaster early warning prompting method and system for an automatic driving vehicle as well as an automatic driving vehicle. The method comprises the following steps: acquiring meteorological data and / or disaster information; acquiring the driving state of each road in a current driving path of the automatic driving vehicle according to the meteorological data and / or thedisaster information; and generating an alarm signal of the current driving path according to the driving state of each road in the current driving path in order to give an early warning prompt according to the alarm signal. Through adoption of the method, a judgment of whether driving is suitable or not can be made according to the meteorological data and / or the disaster information on the current driving path so as to send out an early warning in time, thereby facilitating subsequent path adjustment and making automatic driving safer and more reliable.
Description
technical field [0001] The present invention relates to the technical field of self-driving vehicles, in particular to a disaster warning and prompting method and system for an self-driving vehicle and the self-driving vehicle. Background technique [0002] In related technologies, self-driving cars sense the traffic environment in a limited range through various environmental perception sensors equipped with the vehicle, such as lidar, camera and millimeter-wave radar, and determine their real-time location information through the combination of GPS and inertial navigation. To carry out path planning, combined with controlling the motion state of the vehicle to realize the automatic driving of the vehicle. [0003] However, due to natural conditions such as actual road traffic and weather, there will be emergencies, such as earthquakes, heavy rainfall, severe water accumulation in various depressions, mudslides, sandstorms, etc., which will hinder the safe driving of self-d...
