detailed description

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.

The present invention will be described in detail below with reference to the drawings and embodiments.

FIG. 1 is a flowchart of a method for reminding a vehicle according to an embodiment of the present invention.

As shown in FIG. 1 and combined with FIG. 2, a method for reminding a vehicle according to an embodiment of the present invention includes the following steps:

S101: Detect whether the turn signal is on. For example, it is determined whether the turn signal is turned on and whether the left turn signal is turned on or the right turn signal is turned on according to a signal corresponding to the action of the steering lever.

S102: If the turn signal is on, further obtain navigation information and / or image information in front of the vehicle.

Among them, the image information of the front of the vehicle can be collected by a vehicle camera. For example: capture images of the road in front of the vehicle.

S103: Determine a driving intention of the vehicle according to the navigation information and / or image information in front of the vehicle.

Specifically, the steering or overtaking may be determined based on the navigation information; and / or the presence or absence of an intersection ahead may be identified based on the image information in front of the vehicle, and the steering or overtaking may be determined according to the recognition result.

For example: After the vehicle turns on the turn signal, if there is navigation information, you can determine whether the road ahead has an intersection based on the navigation information, and you can determine whether the vehicle needs to turn into the intersection based on the navigation information (that is, turn), and if so, determine the vehicle The driving intention is to turn, that is, the purpose of turning on the turn signal at this time is to turn. On the contrary, if it is determined according to the navigation that the front intersection does not need to turn, or there is no intersection ahead, it is determined that the purpose of turning on the turn signal of the vehicle at this time is usually to overtake. Of course, there is also the possibility of changing lanes or parking on the side. At this time, it can be further determined whether there are vehicles near the side where the turn signal is turned on. If not, it may be changing lanes or parking on the side.

Another example: After the vehicle turns on the turn signal, you can also determine whether there is an intersection on the road ahead based on the image information in front of the vehicle. If there is an intersection and it is usually safe to drive near the intersection, overtaking will not be performed. Therefore, the vehicle can be determined to be driving The intention is to turn (ie, turn into an intersection), that is, the purpose of turning on the turn signal at this time is to turn. On the contrary, if it is determined that there is no intersection in front of the vehicle according to the image in front of the vehicle, it is determined that the purpose of turning on the turn signal of the vehicle at this time is to overtake. Of course, there is also the possibility of changing lanes or parking on the side. At this time, it can be further determined whether there are vehicles near the side where the turn signal is turned on. If not, it may be changing lanes or parking on the side.

Of course, the navigation information and the image information in front of the vehicle can also be used to determine whether the driving intention is steering or overtaking.

S104: If the driving intention is to turn, a steering icon is projected on the road in front of the vehicle, and if the driving intention is to overtake, a passing icon is projected on the road in front of the vehicle.

For example, there is an intersection ahead, and the vehicle needs to turn. At this time, when approaching the intersection, a steering icon can be projected on the road in front of the vehicle to remind the driver of the need to steer, to avoid the driver unfamiliar with the road and to miss the intersection. It can act as a warning to other vehicles or pedestrians and improve driving safety.

Further, the method further comprises: identifying whether a road is prohibited from driving according to the navigation information and / or image information in front of the vehicle; if so, projecting a prohibition icon onto a road surface in front of the vehicle. Therefore, the driver can be prompted in advance to respond in advance, such as changing the driving route.

In addition, the vehicle reminding method further includes: determining whether there is a pedestrian at the intersection according to the image information in front of the vehicle; and if so, projecting a steering icon under the pedestrian's feet when the vehicle turns.

For example, projecting the turning icon to the foot of a pedestrian includes tracking the pedestrian so that the turning icon projected to the foot of the pedestrian moves with the movement of the pedestrian. Among them, pedestrians can be identified based on the collected images, thereby tracking the pedestrians.

As shown in FIG. 3, during the driving of the vehicle, the vehicle terminal can transmit the navigation information to the main controller according to the vehicle navigation information. The main controller recognizes the navigation information. When the navigation information needs to turn, the main controller transmits a signal to Projection module, the projection module projects the corresponding turn indicator (turn icon) on the road in front of the driver to achieve the purpose of reminding the driver and pedestrians in the surrounding vehicles, and can also project corresponding icons to remind based on navigation, forbidden traffic and other road conditions Driver.

It should be noted that, under the condition that the navigation is not turned on, the driver can recognize the road condition in front of the camera configured on the vehicle, and the projection module will project the corresponding icon according to the identified information. At the same time, the driver can manually turn the steering lever to transmit the steering signal to the main controller, which is output to the projection module after being processed by the main controller, and the projection module projects the corresponding steering mark.

As shown in FIG. 4, the steering mark projection area is an area (n + 1) meters ahead of the driver, and the projection position can be adjusted within the area. The normal default projection is (n + 1) meters. When pedestrians need to be reminded, the icon can be projected under the pedestrian's feet according to the pedestrian information identified by the camera. Among them, n is the distance of the driver's blind zone.

In addition, you can use the navigation information and / or the image information in front of the vehicle to identify the road ahead. When a forbidden sign is recognized, for example, the corresponding prohibited sign will be projected. When the navigation is turned on, the navigation will also provide prohibited information. The driver provides this information to the driver as he enters the lane.

When the vehicle goes straight normally, it will frequently change lanes. When the lane is changed, the steering mark projection will not be performed. When the navigation is turned on, the vehicle position is determined based on the navigation information, whether or not a turn is needed, and the steering projection is not performed when it is far from the intersection. When the navigation is not turned on, the sensor will recognize the road conditions in front of the vehicle and whether there is an intersection to determine whether the vehicle needs to project a turning sign.

When passing through an intersection on a highway, it will determine whether a turn is needed based on the navigation. If a turn is needed, when it is about to reach the intersection, a steering sign is projected to remind the driver to turn. In this scenario, the camera can be used with navigation. When the two types of recognized information are inconsistent, the navigation information is mainly used. In order to prevent the camera from detecting that the intersection is not an intersection that requires a turn, the driver may go in the wrong direction.

In the scene of overtaking to remind the preceding vehicle, for example: during normal driving, overtaking often occurs, especially in the case of oversized trucks. In the related technology, only the horn can be used to remind, the surrounding environment is chaotic, or the vehicle When the volume of other sounds such as internal music is relatively large, there will be situations in which the vehicle in front cannot be alerted, and there is a large hidden danger in driving safety. In the embodiment of the present invention, as shown in FIG. 5, at the beginning of overtaking, a turning icon projected in a direction to go beyond the vehicle is projected in front of the own lane, which is about to overtake the left front of the vehicle. When driving to the parallel state of the vehicle's head, a lane-changing trajectory (ie, the overtaking icon) will be projected to remind the driver on the right that his vehicle's next driving intention can be prepared in advance.

As shown in FIG. 6, when the vehicle normally turns to the intersection and needs to turn, there is a pedestrian passing in front of the intersection that needs to turn. At this time, the steering in the related art will not be able to effectively remind the pedestrian. In the embodiment of the present invention, the sensor Pedestrian information is recognized, a turn sign is projected under the pedestrian's feet, and the icon will flash. Can effectively remind pedestrians in front to avoid vehicles in time.

The method for reminding a vehicle of the present invention can enable a pedestrian or a person in a surrounding vehicle to accurately determine whether the vehicle turns on a turn signal to turn or overtake, and other vehicles or pedestrians can understand the driving intention of the vehicle in time, so that other vehicles can Or pedestrians play a warning role to improve driving safety.

Further, the method also determines the driving intention without turning on the turn signal. In this way, when the vehicle needs to turn, a steering icon is projected on the road in front of the vehicle in advance, so as to remind the driver of the vehicle on the one hand , To avoid the driver being unfamiliar with the road and missing the intersection, on the other hand, it can serve as a warning to other vehicles or pedestrians and improve driving safety.

For example, if the turn signal is not turned on, when it is determined that the driving intention of the vehicle is to turn based on the navigation information and / or image information in front of the vehicle, a steering icon is projected on the road surface in front of the vehicle in advance. On the one hand, it reminds the driver of the vehicle to prevent the driver from unfamiliar with the road and miss the intersection; on the other hand, it can serve as a warning to other vehicles or pedestrians and improve driving safety.
