Problems solved by technology

[0002] When there are no traffic signs, guide lines, zebra crossings, or on ordinary highways, the driver's driving intention cannot be understood by the surrounding pedestrians. Sometimes, the driver's polite behavior is not easy to be noticed by pedestrians in time. , so it may cause traffic accidents due to pedestrians and vehicles rushing, or traffic jams and other problems
[0003] In related technologies, sensors such as cameras or millimeter-wave radars can be used to identify pedestrians and road information. For example, when pedestrians are detected in front, corresponding pedestrian guidance signs are projected according to road conditions. However, there are the following problems: when pedestrians After the guidance sign is projected, it may be due to the driver's misoperation, for example: the accelerator is used as a brake, and pedestrians see that the pedestrian guide sign is giving priority to passing, therefore, it may cause traffic accidents

Embodiment Construction

[0031] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0032] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0033] figure 1 is a flowchart of a vehicle control method according to an embodiment of the present invention.

[0034] Such as figure 1 As shown, the vehicle control method according to one embodiment of the present invention includes the following steps:

[0035] S101: Detect whether there is a pedestrian in front of the vehicle.

[0036] It is possible to detect whether there is a pedestrian in front of the vehicle through the sensor for detecting pedestrians and the distance sensor set on the vehicle, and calculate the position of the pedestrian in front of the vehicle and the distance between the pedestrian and the vehicle through the corresponding algorithm, and can detect the ...

Abstract

The invention provides a vehicle control method, system and vehicle. Among them, the control method of the vehicle includes the following steps: detecting whether there is a pedestrian in front of the vehicle; if there is, judging whether the projection condition is met according to the state of the vehicle; Passage; while projecting pedestrian indicator lines to the area where pedestrians are located, speed limit control is performed on vehicles to avoid vehicle acceleration. The vehicle control method of the present invention can project a pedestrian indicator line to guide pedestrians to pass the road first when a pedestrian passing in front of the vehicle is detected and meets the projection conditions, and at the same time control the speed limit of the vehicle, thereby improving the safety of the vehicle and pedestrians.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle control method, system and vehicle. Background technique [0002] When there are no traffic signs, guide lines, zebra crossings, or on ordinary highways, the driver's driving intention cannot be understood by the surrounding pedestrians. Sometimes, the driver's polite behavior is not easy to be noticed by pedestrians in time. , so it may cause traffic accidents due to pedestrians and vehicles rushing, or traffic jams and other problems. [0003] In related technologies, sensors such as cameras or millimeter-wave radars can be used to identify pedestrians and road information. For example, when pedestrians are detected in front, corresponding pedestrian guidance signs are projected according to road conditions. However, there are the following problems: when pedestrians After the guide sign is projected, it may be due to the driver's misoperation, for example: using...
