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 and system and a vehicle. The vehicle control method comprises the steps of: detecting if pedestrians are in front of the vehicle; if so, judging if projection conditions are met according to the state of the vehicle; if so, projecting pedestrian indicating lines to the areas of the pedestrians to guide priority passing of the pedestrians; and performing the speed limiting control on the vehicle to prevent acceleration of the vehicle when the pedestrian indicating lines are projected to the areas of the pedestrians. The vehicle control method canproject the pedestrian indicating lines to guide the pedestrians for priority passing through highways when the pedestrians are in front of the vehicle and the projection conditions are met, and meanwhile, performs the speed limiting control on the vehicle to improve the safety of the pedestrians and the vehicle.

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...
