Problems solved by technology
[0002] Self-driving vehicles generally drive at a preset speed during driving, but the set speed is not necessarily safe. For example, in foggy days, the sensors on self-driving vehicles have a certain degree of inaccuracy At this time, if the self-driving vehicle is still driving at the speed of a sunny day, accidents are likely to occur
[0003] At present, although the general weather conditions in local areas can be obtained through the weather forecast or the meteorological department, it is difficult to be accurate within a few hundred meters or even tens of meters around each self-driving vehicle. For the fog that suddenly comes from the mountains or the industrial area The erratic smog is even more difficult for self-driving vehicles

The invention discloses an autonomous vehicle and a vehicle speed adjusting method thereof, and relates to the field of unmanned vehicles (or automatic driving or unmanned driving). The autonomous vehicle comprises a vehicle body, and a visibility detection part and a vehicle speed adjusting part which are arranged on the vehicle body; the visibility detection part is used for detecting the current visibility of the environment where the autonomous vehicle is located and generating a visibility detection signal; and the vehicle speed adjusting part is used for adjusting the traveling speed ofthe autonomous vehicle according to the received visibility detection signal. Automatic speed limiting of the autonomous vehicle is achieved when the fog or smoke concentration of the environment where the autonomous vehicle is located is too high, and the driving safety of the autonomous vehicle in foggy days is improved.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of vehicles, and in particular to an automatic driving vehicle and a method for adjusting the vehicle speed thereof. Background technique [0002] Self-driving vehicles generally drive at a preset speed during driving, but the set speed is not necessarily safe. For example, in foggy days, the sensors on self-driving vehicles have a certain degree of inaccuracy At this time, if the self-driving vehicle is still driving at the speed of a sunny day, accidents are prone to occur. [0003] At present, although the general weather conditions in local areas can be obtained through the weather forecast or the meteorological department, it is difficult to be accurate within a few hundred meters or even tens of meters around each self-driving vehicle.
