Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Example one

The embodiment of the invention provides a car lamp control method, which is applied to the situation that a car is driven at night, for example, the car speed is faster on an expressway, or the surrounding is darker on a rural road or a plurality of intersections. In these cases, the driver has low sensitivity to the intersection to be turned, and is likely to miss the intersection to be turned.

The present invention provides a vehicle lamp control method, as shown in fig. 1, including:

s101, acquiring navigation information of a vehicle running at night;

s102, acquiring intersection position information of a direction to be turned based on the navigation information;

s103, determining a reminding road section for the driver based on the intersection position information;

s104, generating at least two intersection reminding instructions when the vehicle runs to the reminding road section;

and S105, controlling the vehicle lamp on the side of the direction to be turned of the vehicle to point to the intersection position to remind the driver of turning at the intersection position each time the intersection reminding instruction is received.

In S101, navigation information of the vehicle driving at night is obtained, which may be obtained by a navigation system (e.g., beidou navigation system) integrated in the vehicle, or obtained by a navigation subsystem installed on a mobile terminal of the driver, where the mobile terminal and the vehicle may share the navigation information.

The navigation information may be a route selected or preset by the driver, and is not limited herein.

The navigation information comprises detailed map information, intersection positions, high-definition images of intersections, information of current positions of vehicles and the like.

Next, in S102, intersection position information of the direction to be turned is acquired based on the navigation information.

Specifically, during the driving of the vehicle, a plurality of intersections to be turned, for example, A, B, C, D intersections to be passed in turn as shown in fig. 2, are experienced. The intersection position information is obtained from the navigation information.

Then, S103 determines a warning link to the driver based on the intersection position information.

The reminding road section is a preset road section in front of the intersection position of the direction to be turned, and can be set according to reminding times. For example, the distance is 1km or 2km from the direction to be turned, which is not limited herein. If the reminding times are more, the reminding road section is set to be longer.

Next, in S104, when the vehicle travels to the reminding link, at least two intersection reminding instructions are generated.

When the vehicle runs to the reminding road section, the vehicle is indicated to turn, therefore, in the process of reaching the intersection position in the direction to be turned, namely the reminding road section, the reminding can be carried out for multiple times, and therefore, at least two intersection reminding instructions are generated. The at least two intersection reminding instructions are separated by time, for example, reminding every 5 minutes. The reminding may also be performed at intervals of a distance, for example, at intervals of 500 meters, and is not limited herein. The reminding instruction can be used for reminding the driver of preparing for turning.

Finally, when S105 is executed, each time an intersection reminding instruction is received, the lamp on the side of the vehicle to be turned is controlled to point to the intersection position to remind the driver to turn at the intersection position, as shown in fig. 3.

Under the night condition, light is darker, and crossing degree of recognition is lower, consequently, treats the directional crossing position of car light of turning direction side through the vehicle, and the opposite side car light still keeps original direction for the driver not only can see clearly the road of current direction of traveling, also can see clearly the crossing position of treating the turning direction in addition, and then reminds the driver to prepare the turn at the directional crossing position of this car light.

Wherein, control vehicle treats that the car light of turning direction side points to the crossing position, because the vehicle is driven on the road, the position of vehicle is changed promptly, treats that the crossing position of turning direction is fixed, can detect this crossing position of treating the turning direction by the detection device on the vehicle, and this detection device includes: the vehicle angle detector, the radar, the camera and the like further obtain the deflection direction of the vehicle lamp according to the intersection position and the position of the vehicle, and the deflection direction is changed along with the movement of the vehicle.

When an intersection reminding instruction is received each time, whether light rays of a vehicle lamp at the side of a to-be-turned direction of the vehicle pointing to the intersection position are blocked by an obstacle needs to be judged firstly based on a detection structure of a radar; if not, controlling the vehicle lamp on the side of the vehicle to be turned to point to the intersection position so as to remind the driver of turning at the intersection position.

Specifically, the radar detects according to the direction of the vehicle lamp on the side of the vehicle to be turned to the intersection, and the radar detects to judge whether the obstacle exists or not, so that the situation that when other vehicles exist between the vehicle and the position of the intersection pointed by the vehicle lamp on the side of the vehicle to be turned is avoided, the direction of the vehicle lamp is blocked, other vehicles are interfered, and the intersection cannot be identified by a driver.

When the influence of the obstacle is eliminated, the vehicle lamp on the side of the vehicle to be turned is controlled to point to the intersection position so as to remind the driver of turning at the intersection position.

In an alternative embodiment, each time an intersection reminding instruction is received, a vehicle lamp on the side of the vehicle to be turned is controlled to point to an intersection position, the vehicle lamp is controlled to flicker, and a same-side steering lamp behind the vehicle is turned on to remind a driver of turning at the intersection position.

By means of the method for deflecting the direction of the vehicle lamp, the driver can be reminded of turning at the position of the intersection in time, and pedestrians at the intersection can be reminded of avoiding in time by controlling the vehicle lamp to flicker. Meanwhile, the same-side steering lamp behind the vehicle is turned on to remind the vehicle and the pedestrian behind the vehicle that the vehicle is about to turn and please drive cautiously.

In an optional embodiment, each time an intersection reminding instruction is received, a lamp on the side of the vehicle to be turned is controlled to point to the intersection position to remind the driver to turn at the intersection position, and the method further comprises the following steps:

sending a voice query to the driver; judging whether a voice response of the driver is received or not; and if so, controlling the vehicle lamp to recover to the driving direction.

If not, namely the voice response of the driver is not received, the vehicle lamp is controlled to return to the driving direction, and meanwhile the next intersection reminding is started.

In a specific implementation manner, the above-mentioned car light that needs to control the pointing direction may be a lighting lamp specifically, or an indicator light that is set separately, and if the light is an indicator light, the indicator light is a light with a marking color, for example, a red or green laser light color, so that the driver can distinguish more easily.

The generated at least two intersection reminding instructions can be three times or four times, and intersection indication continuity is improved by increasing the times of the reminding instructions.

One or more technical solutions in the embodiments of the present invention have at least the following technical effects or advantages:

the invention provides a vehicle lamp control method, which comprises the following steps: acquiring navigation information of a vehicle running at night; acquiring intersection position information of the direction to be turned based on the navigation information; determining a reminding road section for a driver based on the intersection position information; when the vehicle runs to the reminding road section, generating at least two intersection reminding instructions; when an intersection reminding instruction is received each time, the vehicle lamp on the side of the to-be-turned direction of the vehicle is controlled to point to the intersection position so as to remind a driver to turn at the intersection position, and therefore the intersection condition can be accurately identified through at least two times of reminding, and turning preparation can be made in time.
