Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] figure 1 It is a flowchart of a method for adjusting vehicle speed provided by an embodiment of the present invention. see figure 1 , the method includes:

[0032] 101. Acquire dynamic information of a first target, where the first target is a target within a specified range around the vehicle obtained through detection by the vehicle.

[0033] The first target refers to the target within the designated range around the vehicle obtained by the vehicle through detection, wherein the designated range refers to the detectable range of the distance sensor, specifically, the designated range can be determined by the range of the lateral azimuth angle and the range of the longitudinal distance to make sure. For example, the detect...

Abstract

The invention discloses a method, device and system for adjusting the running speed of a vehicle, belonging to the technical field of vehicles. The method includes: acquiring dynamic information of a first target, the first target is a target within a specified range around the vehicle obtained by the vehicle through detection; according to the dynamic information of the first target, determining A second target in the same lane; adjusting the driving speed of the vehicle according to the dynamic information of the second target. The present invention automatically acquires the dynamic information of the second target in the own lane, and automatically adjusts the driving speed of the vehicle according to the dynamic information of the second target, reduces the manpower operation in the process of adjusting the driving speed of the vehicle, and further improves the speed of adjusting the driving speed of the vehicle. degree of automation.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a method, device and system for adjusting the driving speed of a vehicle. Background technique [0002] With the continuous development of economy and society, the use of vehicles has become more and more common. While vehicles bring convenience to people's lives, they also create a series of problems. For example, traffic accidents occur frequently due to reasons such as traffic jams or inattention of drivers, which cause great losses to people's lives, health and property safety. [0003] At present, when the distance between vehicles is relatively short, the driver usually needs to use visual inspection to roughly understand the information of the vehicle in front in the lane, such as the distance between the vehicle in front and the vehicle in front, and the speed of the vehicle in front. Then the driver adjusts his own vehicle speed according to the acquired infor...
