Description

Reversing lighting method, reversing lighting equipment, vehicle and storage medium Technical Field The application relates to the technical field of automobiles, in particular to a reversing lighting method, reversing lighting equipment, a vehicle and a storage medium. Background When reversing operation is performed at night or in a dim-light environment, a driver often faces the potential safety hazard of unclear vision. At present, the main scheme for improving the reversing vision mainly has the following limitations that firstly, a reversing image system is relied on, but the image quality is poor under the low illumination condition, the visual range is limited, and secondly, a 360-degree panoramic image system is adopted, so that a more comprehensive surrounding environment view can be provided, but the system is complex and the cost is high. On the other hand, the brightness of the backup lamp of the vehicle is generally low, and the illumination range is concentrated in a narrow area right behind, and it is difficult to sufficiently illuminate the side rear area. In order to substantially improve the reversing lighting effect, the prior art has a scheme of adding special auxiliary lights, but the cost and the wiring complexity of vehicle hardware are obviously increased, and the vehicle is difficult to popularize and apply to entrance-level or economic vehicle types pursuing cost control. Disclosure of Invention In view of the above, the present application is directed to providing a reversing lighting method, a device, a vehicle and a storage medium, which can effectively reduce side rear lighting blind areas during reversing without adding additional lighting hardware, and greatly reduce implementation cost while remarkably improving reversing safety at night, thereby being beneficial to wide application in low-profile vehicle types. According to a first aspect of the application, a reversing lighting method is provided, and the reversing lighting method comprises the steps of obtaining image information of a driver of a target vehicle when the target vehicle is in a reversing mode and in a low-illumination environment, judging whether the driver has an intention of observing the rear of the target vehicle or not based on the image information, and generating a first vehicle lamp control instruction if the driver has the intention of observing the rear of the target vehicle, wherein the first vehicle lamp control instruction is used for lighting a target vehicle lamp which is arranged behind the target vehicle and does not comprise a reversing lamp of the target vehicle. Through multiplexing current lamps and lanterns such as back fog lamp, brake lamp, can provide more extensive, brighter side rear illumination for the driver than traditional reversing light to effectively compensatied the visual field blind area that leads to jointly by low illumination environment and the limited irradiation range of standard reversing light, promoted the environmental perception ability and the security of reversing operation. Secondly, because the target car lights such as the steering lights, the rear fog lights and the like bear other specific functions in the conventional driving scene, if the target car lights are continuously lightened without distinction, the dazzling interference to other surrounding traffic users or the transmission of wrong car state signals are very easy to happen. By the control logic of on-demand lighting, unnecessary lighting time of the non-backup lamp lamps in the reversing process is obviously shortened, so that continuous glare interference to other road users outside the vehicle is avoided to the greatest extent while effective light supplementing is realized, wrong vehicle state signals possibly transmitted due to irregular lighting of the lamp light are prevented, and balance between lighting effect and driving safety is achieved. Optionally, the target car lamp comprises at least one of a rear fog lamp, a brake lamp and a rear steering lamp. Optionally, the judging whether the driver has the intention to observe the rear of the target vehicle comprises judging whether the driver has the intention to observe the rear of the target vehicle according to the fact that the driver has the intention to observe the rear of the target rearview mirror or not, and the generating a first vehicle lamp control instruction if the driver has the intention to observe the rear of the target vehicle comprises generating a first vehicle lamp control instruction for lighting a first target vehicle lamp if the driver has the intention to observe the rear of the target vehicle, wherein an illumination coverage area of the first target vehicle lamp is overlapped with a target observation area, and the target observation area is an area observed by the driver of the target vehicle through the target rearview mirror. The intention of the driver for observing the rear view mirror of the target is
