Embodiment Construction

[0021] The embodiment of the present invention provides a kind of automatic driving method, it comprises the following steps:

[0022] Obtain the speed, distance and lane data of vehicles within a certain range around; the lane data in this embodiment includes two lanes, one is an overtaking lane, and the other is an ordinary lane;

[0023] According to the state of the own vehicle and the state data of the vehicles within a certain range, determine the driving operation that the vehicle can perform. distance, and the speed and distance of vehicles in front of and behind vehicles in the overtaking lane;

[0024] Specifically, the following driving operations are included:

[0025] Keep the original lane driving: When the speed of the vehicle ahead in the same lane is higher than that of the vehicle, the vehicle will keep the original speed;

[0026] Overtaking driving: When the speed of the vehicle within a certain distance ahead of the same lane is lower than that of the ve...

Abstract

The invention provides an automatic driving method. The method includes the following steps of obtaining the speeds of surrounding vehicles within a certain range, the distances between a host vehicle and the surrounding vehicles, and lane data; and judging driving operations which can be executed by the host vehicle according to the state of the host vehicle and the obtained state data of the surrounding vehicles within a certain range, wherein the driving operations specifically include continuing driving on an original lane, overtaking driving, lane changing driving and deceleration driving. By means of the automatic driving method provided by the invention, the actions of lane changing, overtaking and the like can be completed under the condition that safety is guaranteed to the maximum extent, safety of front and rear vehicles is guaranteed, and a good technical foundation is provided for full-automatic driving.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an automatic driving method. Background technique [0002] With the rapid growth of the number of motor vehicles, the traffic pressure that cities are facing is also increasing. However, the widening of roads is limited by urban planning and the building environment, and it is difficult to achieve linear growth with the growth rate of motor vehicles, making traffic congestion an inevitable problem for large and medium-sized cities. Therefore, how to improve road traffic capacity under the current road conditions has become a key research direction of current motor vehicle technology and traffic development. The motor vehicle train technology based on automatic driving and intelligent assisted driving technology can effectively increase the capacity and flow of motor vehicles on the road, thereby ensuring the smoothness of the road. Moreover, the automatic driving tech...
