Problems solved by technology

[0003] However, in the process of implementing the present invention, the inventors of the present invention found that: when the current unmanned vehicle is driving in the driving lane, when it needs to change lanes to the target lane, it will usually be at the nearest trigger target that triggers the lane change demand. It is possible to merge into road sections for lane change, but when the length of the nearest road section that can be merged into is too short, it is easy to cause unmanned vehicles to fail to merge.

Embodiment 1

[0026] see figure 1 , figure 1 It is a schematic flowchart of a method for driving a vehicle provided by an embodiment of the present invention, and the method includes the following steps:

[0027]Step S101 , according to the preset driving route of the unmanned vehicle, determine whether the unmanned vehicle needs to change lanes, and if so, execute step S102 .

[0028] Wherein, if the unmanned vehicle does not need to change lanes, it is only necessary to control the unmanned vehicle to drive on the current driving lane, and after the preset time, step S101 is executed, that is, after the preset time, the Determine whether the driverless vehicle needs to change lanes.

[0029] When the user uses the driverless vehicle, a preset driving route from the origin to the destination will be generated. The preset driving route may be a driving route recommended by the unmanned vehicle according to the driving time, starting point, destination and the user's driving habits, or ma...

Embodiment 2

[0115] see Figure 9 , Figure 9 It is a schematic diagram of a device for driving a vehicle provided by an embodiment of the present invention. The device 400 includes: a first judgment module 401, an acquisition module 402, a second judgment module 403, a first control module 404, a third judgment module 405, a A second control module 406 , a fourth judgment module 407 and a third control module 408 . Wherein, the first judgment module 401 is used for judging whether the unmanned vehicle needs to change lanes according to the preset driving route of the unmanned vehicle; the obtaining module 402 is used for if the unmanned vehicle needs to change lanes If there is a lane change requirement, the target lane corresponding to the lane change requirement is obtained; the second judgment module 403 is used for when the target lane has the first non-merging road section, a first mergeable road segment, a second non-mergeable road segment, a second mergeable road segment, a third...

Embodiment 3

[0124] see Figure 10 , Figure 10 It is a schematic diagram of the hardware structure of the unmanned vehicle provided by the embodiment of the present invention. The unmanned vehicle 500 includes: one or more processors 501 and a memory 502, Figure 10 Take a memory as an example.

[0125] The processor 501 and the memory 502 may be connected through a bus or in other manners. In this embodiment of the present invention, the connection through a bus is used as an example.

[0126]As a non-volatile computer-readable storage medium, the memory 502 can be used to store non-volatile software programs, non-volatile computer-executable programs and modules, such as programs corresponding to the method for driving a vehicle in the embodiment of the present invention Directives / modules (e.g. attached Figure 9 modules shown). The processor 501 executes various functional applications and data processing of the device for driving the vehicle by running the non-volatile software ...

Abstract

The embodiment of the invention discloses a vehicle driving method. The method comprises the steps of judging whether an unmanned vehicle has a lane changing demand or not; if yes, obtaining a target lane corresponding to the lane changing demand; judging whether the length of a first mergeable road section is greater than or equal to a first preset threshold value; if yes, controlling the unmanned vehicle to merge on the first mergeable road section; if not, judging whether the length of a second mergeable road section is greater than or equal to the first preset threshold value; if yes, controlling the unmanned vehicle to merge on the second mergeable road section; if not, judging whether the length of a third mergeable road section is greater than or equal to a second preset threshold value; and if yes, controlling the unmanned vehicle to merge on the third mergeable road section. The unmanned vehicle can merge into the target lane on the road section which is closest to the triggering target of the lane changing demand and has the length larger than the first preset threshold value, and therefore successful lane merging of the unmanned vehicle can be achieved, and the driving time of the unmanned vehicle is guaranteed.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of unmanned vehicles, in particular to a method and device for driving a vehicle, and an unmanned vehicle. Background technique [0002] An unmanned vehicle is a kind of intelligent car, also known as a wheeled mobile robot. A vehicle that requires a driver to start, drive, and stop. Its smart pilot includes high-precision maps, positioning and perception, and more. The emergence of unmanned vehicles will undoubtedly bring unprecedented experience to people's travel. [0003] However, in the process of implementing the present invention, the inventors of the present invention found that: when the current unmanned vehicle is driving in the driving lane, when it needs to change lanes to the target lane, it will usually be at the nearest trigger target that triggers the lane change demand. It is possible to merge into road sections for lane change, but when the length of the nearest roa...
