AI Technical Summary

Problems solved by technology

However, vehicles that use the L2 car-following function often lose the car-following target vehicle and miss the high-speed ramp due to the driver's inattention during driving, which reduces the efficiency of people's travel and wastes valuable leisure time
[0005] At the same time, the car-following function of mass-produced vehicles can only be realized at low speeds, and the small-angle car-following and lane-changing operations can be performed at low speeds and without lane lines by using the front millimeter-wave radar to track the position of the vehicle in front, which cannot be realized at low speeds. Steady following function on urban express roads or highways

Embodiment

[0064] figure 1 It is a schematic flow chart of a vehicle automatic car-following control method provided by an embodiment of the present invention. This specification provides the method operation steps as described in the embodiment or flow chart, but based on routine or non-creative work, it may include more or more Fewer operating steps. The sequence of steps enumerated in the embodiments is only one of the execution sequences of many steps, and does not represent the only execution sequence. When an actual system or server product is executed, the methods shown in the embodiments or drawings may be executed sequentially or in parallel (for example, in a parallel processor or multi-thread processing environment). specific as figure 1 As shown, the method may include:

[0065] S100: Acquire the following target vehicle according to the first image information in front of the own vehicle.

[0066] In some feasible implementation manners, the ego vehicle may acquire video...

Abstract

The invention discloses a vehicle automatic car-following control method, device and equipment. The method includes: acquiring a car-following target vehicle according to the first image information in front of the vehicle; acquiring the second image information in front of the vehicle in real time and judging the second image information Whether there is a car-following target vehicle in the second image information; if there is no car-following target vehicle in the second image information, then obtain the road condition information around the self-vehicle in real time and control the self-vehicle to change lanes according to the road condition information; the second image information ahead and judge whether there is a car-following target vehicle in the second image information; Generate car-following control information of the self-vehicle; control the self-car to follow the car-following target vehicle according to the car-following control information. By adopting the invention, stable car following on urban express roads and expressways can be realized.

Description

technical field [0001] The invention relates to vehicle automatic driving technology, in particular to a vehicle automatic car-following control method, device and equipment. Background technique [0002] The Advanced Driving Assistant System (ADAS) uses various sensors installed on the vehicle to sense the environment around the vehicle at any time during the driving process, collect data, and carefully identify and detect static and dynamic objects. Combined with the map data of the navigator, the system performs calculation and analysis, so that the driver can be aware of possible dangers in advance, and the comfort and safety of the vehicle can be effectively increased. With the mature application of advanced driving assistance system functions, current mass-produced vehicles have realized driving assistance functions such as lane keeping, intelligent navigation, highway assistance, and traffic jam assistance, alleviating the physical and mental stress caused by long-ter...
