Embodiment Construction

[0037] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0038] The driving method provided by the embodiment of the present invention is implemented in an unmanned vehicle, and is used for the autonomous cruising of the unmanned vehicle in the automatic driving mode. The method flow chart is as follows figure 1 shown, including the following steps:

[0039] Step 110, the vehicle control unit acquires driving route information;

[0040] Specifically, an unmanned vehicle includes a vehicle control unit and a perception unit. Wherein, the vehicle control unit can be understood as a control module for controlling the driving of the vehicle. The perception unit can be understood as a module that perceives the surrounding environment of the vehicle. The perception unit includes a positioning module, a radar module and a camera module. The positioning module is used to obtain ...

Abstract

The embodiment of the present invention relates to a driving method, including: the vehicle control unit analyzes the driving route information to obtain the cruise start position and the cruise end position; when the actual position of the vehicle has reached the cruise start position, the vehicle control unit detects The unit obtains the actual road environment information; and, the vehicle control unit monitors the road gradient data through the sensor in the vehicle; the vehicle control unit determines the first driving speed control parameter corresponding to the road gradient data according to the road gradient data; and, the vehicle control unit according to the The actual road environment information determines the lane characteristic data, and determines the second driving speed control parameter corresponding to the lane characteristic data according to the fixed lane characteristic data; according to the first driving speed control parameter, the second driving speed control parameter and the preset vehicle speed The data obtains target travel speed data.

Description

technical field [0001] The invention relates to the field of automatic driving, in particular to a driving method. Background technique [0002] With the development of the economy and the rise of artificial intelligence technology, self-driving cars are getting more and more attention from the market. Self-driving cars refer to relying on the cooperation of artificial intelligence, visual computing, radar, monitoring devices and global positioning systems, so that computers can automatically and safely operate motor vehicles without any active human operation. The market predicts that the popularization of self-driving cars can reduce the incidence of traffic accidents, reduce traffic congestion, reduce the cost of investing in transportation infrastructure, and reduce environmental pollution. [0003] But at present, the relevant technologies in the field of autonomous driving are not yet mature, making it impossible for autonomous vehicles to drive on actual roads. Espe...
