Embodiment 1

[0084] see figure 1 , figure 1 It is a schematic flowchart of a control method for automatically avoiding special vehicles disclosed in an embodiment of the present invention. Wherein, the method shown in the embodiment of the present invention is applied to the vehicle-mounted system, the vehicle-mounted system is installed on the intelligent driving vehicle, and at least three sound sensing devices are respectively installed in different directions of the intelligent driving vehicle. Such as figure 1 As shown, the control method for this automatic avoidance special vehicle may include the following steps:

[0085] 101. The vehicle-mounted system determines the first location information of the special vehicle according to the sound receiving time when any three of the at least three sound sensing devices receive the alarm sound signal of the special vehicle.

[0086] In the embodiment of the present invention, the vehicle-mounted system detects the alarm sound signal of t...

Embodiment 2

[0099] see figure 2 , figure 2It is a schematic flowchart of another control method for automatically avoiding special vehicles disclosed in the embodiment of the present invention. Wherein, in addition to at least three sound sensing devices installed in different directions of the intelligent driving vehicle, there is at least one image sensing device installed on the intelligent driving vehicle. Such as figure 2 As shown, the control method for this automatic avoidance special vehicle may include the following steps:

[0100] 201. The vehicle-mounted system judges whether any one of the at least three sound sensing devices receives an alarm sound signal of a special vehicle. If yes, execute step 202; otherwise, end this process.

[0101] As an optional implementation manner, before performing step 201, the vehicle-mounted system can pre-process the alarm sound signals of special vehicles received by at least three sound sensing devices, such as sampling, quantificati...

Embodiment 3

[0127] see image 3 , image 3 It is a schematic flowchart of another control method for automatically avoiding special vehicles disclosed in the embodiment of the present invention. Such as image 3 As shown, the control method for this automatic avoidance special vehicle may include the following steps:

[0128] 301-307. Wherein, steps 301 to 307 are the same as steps 201 to 207 described in Embodiment 2, and will not be repeated in this embodiment of the present invention.

[0129] 308. The in-vehicle system obtains the first probability value that the special vehicle is located at the target position according to the alarm sound signal of the special vehicle; and obtains the second probability value that the special vehicle is located at the target position according to the target image of the special vehicle.

[0130] 309. The vehicle-mounted system obtains a second target probability value that the special vehicle is located at the target position according to the fi...

Abstract

The embodiment of the invention relates to the technical field of intelligent driving vehicles and discloses a control method for automatically yielding special vehicles and a vehicle-mounted system.The control method for automatically yielding the special vehicles is applied to the vehicle-mounted system; the vehicle-mounted system is mounted on the intelligent driving vehicle; at least three sound sensing equipment are correspondingly mounted in different azimuths of the intelligent driving vehicle; and the control method for automatically yielding the special vehicles comprises the steps of determining first position information of the special vehicle according to a sound receiving time at which any three sound sensing equipment in the at least three sound sensing equipment receive analarming sound signal of the special vehicle, determining a running path of the special vehicle according to the first position information of the special vehicle, judging whether the intelligent driving vehicle is on the running path or not, and if the intelligent driving vehicle is on the running path, controlling the intelligent driving vehicle to adopt an yielding measure to yield to the special vehicle. According to the control method for automatically yielding special vehicles and the vehicle-mounted system, disclosed by the embodiment of the invention, drivers can identify and automatically yield to the special vehicle in time, and meanwhile, requirements of laws and regulations are satisfied, and the traveling efficiency of the special vehicles are enhanced.

Description

technical field [0001] The invention relates to the technical field of intelligent driving vehicles, in particular to a control method and a vehicle-mounted system for automatically avoiding special vehicles. Background technique [0002] Special vehicles (such as police cars, fire trucks, ambulances or engineering rescue vehicles, etc.) enjoy the priority of road traffic when performing emergency tasks, and can use sirens, signs, and lamps, and they are not allowed to drive under the premise of ensuring safety. Restrictions on routes, direction of travel, speed of travel and signal lights. When encountering a special vehicle that is performing an emergency task, other vehicles should give way. [0003] Nowadays, with the popularity of intelligent driving (also known as autonomous driving) vehicles, it has become a daily phenomenon for intelligent driving vehicles to drive on the road as a means of transportation. In practice, it has been found that when an intelligent dri...
