and screening the driving data according to the effective detection range to obtain target driving data corresponding to the effective detection range.
It should be noted that: in the prior art, a single sensor and a plurality of sensors acquire data; the perception of a single sensor can be influenced by surrounding environment, such as weather, illumination, road types, road arrangement, ground identification and other factors, more false detections can be generated in a complex scene, and more false detections are generated particularly in special scenes, such as tunnels or underground garages; the scheme of arranging multiple sensors can greatly increase the difficulty and cost of the development of the automatic driving technology, which means that a large amount of sensor data and more redundant data need to be processed in real time, higher bus bandwidth is needed, and a chip with higher performance is adopted, so that the production cost is obviously increased; in order to solve the above problem, in this embodiment, based on a mapping relationship between pre-stored scene information and an effective detection range of the distance sensor, an effective detection range corresponding to the target scene information is determined, and then based on the distance sensor, driving data of the vehicle in an actual detection range is acquired; the driving data are screened according to the effective detection range to obtain target driving data corresponding to the effective detection range, so that the data processing amount of the vehicle in judging road condition information is reduced, the influence of invalid driving data on automatic driving of the vehicle can be avoided, and the false detection rate of the road condition information is increased due to the fact that the invalid driving data are processed; the vehicle can also improve safety and stability of automatic driving only by processing the target running data.
It should also be noted that: the embodiment also reduces the number of the sensors, avoids using a plurality of sensors to cause more redundant data, and reduces the production cost to a certain extent.
