Description
[0001] The present disclosure claims the priority of the Chinese patent application filed on September 3 0 th, 2018 by Great Wall Motor Company Limited with the application number of 201811159925.5 and the title of "PROMPTING METHOD AND SYSTEM FOR VEHICLE, AND VEHICLE".
[0002] The present disclosure relates to the technical field of cars, and particularly relates to a method and system for alerting by a vehicle, and a vehicle.
[0003] In the related art, the headlamps of vehicles merely have a simple function of illumination. When it is required to steer or to overtake, the driver lightens the turn light by operating a steering driving lever, to alert pedestrians and surrounding vehicles.
[0004] That has a problem. Because, when the driver lightens the turn light by operating the steering driving lever, pedestrians or the on-board persons of surrounding vehicles, when seeing the light, cannot clearly know whether it will steer or will overtake, or, in other words, pedestrians or surrounding vehicles cannot exactly know whether the vehicle intends to steer or intends to overtake, the risk of a traffic accident exists.
[0005] In view of the above, the present disclosure provides a method for alerting by a vehicle. The method for alerting by a vehicle can enable a pedestrian or an on-board person in a surrounding vehicle to accurately determine whether the vehicle is intending to steer or to overtake when turning on a turn light, whereby the vehicle or the pedestrian can timely know the travelling intention of the vehicle, so the vehicle or the pedestrian can be alerted, to improve the safety in driving.

[0035] It should be noted that, subject to the avoiding of any conflict, the embodiments and the features of the embodiments of the present disclosure can be combined.
[0036] The present disclosure will be described in detail below with reference to the drawings and the embodiments.
[0037] Fig. 1 is a flow chart of the method for alerting by a vehicle according to an embodiment of the present disclosure.
[0038] As shown in Fig. 1, and referring to Fig. 2, the method for alerting by a vehicle according to an embodiment of the present disclosure comprises the steps of:
[0039] S101: detecting whether a turn light has been turned on. For example, it is judged, according to a signal corresponding to the action of a steering driving lever, whether a turn light has been turned on, and whether a left turn light has been turned on or a right turn light has been turned on.
[0040] S102: if the turn light has been turned on, acquiring navigation information and/or image information of front of the vehicle.
[0041] The image information of front of the vehicle may be obtained by collecting by using an on-board camera. For example, an image of the road in front of the vehicle is collected.
[0042] S103: according to the navigation information and/or the image information of front of the vehicle, determining a travelling intention of the vehicle.
[0043] Particularly, this step may comprises, according to the navigation information, determining to steer or to overtake; and/or, according to the image information of front of the vehicle, identifying whether there is an intersection in front, and according to the identification result, determining to steer or to overtake.
[0044] For example, after the vehicle has turned on a turn light, if navigation information exists, this step may, according to the navigation information, judge whether there is an intersection in the road in front, and may, according to the navigation information, judge whether the vehicle requires to turn into the intersection (i.e., steering); if yes, determine that the travelling intention of the vehicle is steering, or, in other words, the purpose of turning on the turn light at the moment is in order to steer; and if no, if it is determined, according to the navigator, that steering is not required at the intersection in front, or that there is no intersection in front, determine that the purpose of turning on the turn light at the moment of the vehicle is usually in order to overtake. Certainly, the purpose might also be lane changing or pulling over, in which case, this step may further determine whether there is a vehicle adjacent to the side where the turn light is turned on, and if no, determine that the purpose might be lane changing or pulling over.
[0045] As another example, after the vehicle has turned on a turn light, this step may also, according to the image information of front of the vehicle, determine whether there is an intersection in the road in front; if there is an intersection, because, adjacent to an intersection, for the safety of travelling, acceleration and overtaking are usually not performed, may determine that the travelling intention of the vehicle is steering (i.e., turning into the intersection), or, in other words, the purpose of turning on the turn light at the moment is in order to steer; and if no, if it is determined, according to the image of front of the vehicle, that there is no intersection in front, determine that the purpose of turning on the turn light at the moment of the vehicle is in order to overtake. Certainly, the purpose might also be lane changing or pulling over, in which case, this step may further determine whether there is a vehicle adjacent to the side where the turn light is turned on, and if no, determine that the purpose might be lane changing or pulling over.
[0046] Certainly, this step may also judge whether the travelling intention is steering or overtaking by using both of the navigation information and the image information of front of the vehicle.
[0047] S104: if the travelling intention is steering, projecting a steering pattern onto a road surface in front of the vehicle, and if the travelling intention is overtaking, projecting an overtaking pattern onto the road surface in front of the vehicle.
[0048] For example, if there is an intersection in front and the vehicle requires to steer, at this point, when approaching the intersection, the vehicle may project the steering pattern onto the road surface in front of the vehicle, which, on one hand, alerts the driver the necessity of steering, to avoid missing the intersection due to the unfamiliarity of the road of the driver, and, on the other hand, alerts the other vehicles or pedestrians, to improve the safety in driving.
[0049] Optionally, the method further comprises: according to the navigation information and/or the image information of front of the vehicle, identifying whether a road is restricted from travelling; and if yes, projecting a travelling-restriction pattern onto the road surface in front of the vehicle. That can prompt the driver in advance, to react beforehand, for example, changing the driving route.
[0050] Optionally, the method for alerting by a vehicle further comprises: according to the image information of front of the vehicle, determining whether there is a pedestrian at an intersection; and if yes, when the vehicle is steering, projecting the steering pattern under a foot of the pedestrian.
[0051] For example, the step of projecting the steering pattern under a foot of the pedestrian comprises: tracking the pedestrian, to enable the steering pattern projected under the foot of the pedestrian to move with the pedestrian. The pedestrian may be identified according to the collected image, thereby tracking the pedestrian.
[0052] As shown in Fig. 3, the method may comprise, in the travelling of the vehicle, according to the navigation information of the vehicle, transmitting by a vehicle terminal the navigation information to a main controller, identifying by the main controller the navigation information, if the navigation information indicates that it is required to steer, transmitting by the main controller a signal to the projecting module, and projecting by the projecting module a corresponding steering identifier (steering pattern) onto the road surface in front of the driver, to alert the driver and surrounding vehicles and pedestrians. Moreover, road conditions such as restriction from travelling may be identified according to the navigator, and corresponding patterns may be projected, to alert the driver.
[0053] It should be noted that, in a case in which the navigator is not started up, the driver may identify the road condition in front by using a camera provided at the vehicle, and the projecting module projects the corresponding pattern according to the identified information. Moreover, the driver may manually operate the steering driving lever, to transmit a steering signal to the main controller, the main controller processes the signal and outputs the signal to the projecting module, and the projecting module projects the corresponding steering identifier.
[0054] As shown in Fig. 4, the projection area of the steering identifier is the area in front of the driver with a distance no less than (n+1) meters, and the projection position may be freely adjusted within the area. Normally, the projection is defaulted to be at the position of (n+1) meters. When it is required to alert, for example, when there is a pedestrian, a pattern may be projected under the feet of the pedestrian according to the pedestrian information identified by a camera. N is the distance of the blind area of the driver.
[0055] In addition, the method may comprise identifying the road condition in front by using the navigation information and/or the image information of front of the vehicle, and, if, for example, a travelling-restriction identifier is identified, projecting a corresponding travelling-restriction identifier. If the navigator has been started up, the navigator will also provide the travelling-restriction information, and the information may be provided to the driver when the driver is entering the lane.
[0056] Vehicles, in normal straight travelling, frequently change lane, and, in lane changing, when the steering driving lever is operated, the steering identifier will not be projected. If the navigator has been started up, it is determined according to the navigation information the position of the vehicle and whether to steer, and if the distance from an intersection is large, steering projection is not performed. If the navigator is not started up, a sensor identifies the road condition in front of the vehicle and whether there is an intersection, to determine whether the vehicle requires to project the steering identifier.
[0057] When crossing an intersection in an expressway, the vehicle judges, according to the navigator, whether it is required to steer, and if it is required to steer, when the intersection will be immediately reached, projects the steering identifier, to alert the driver to steer. In such a scene, a camera may be used to cooperate with the navigator, and if the results of the identification of them are not consistent, the navigation information prevails, to prevent that the intersection detected by the camera is not the intersection where steering is required, which results in an erroneous turning of the driver.
[0058] A scene of alerting a vehicle ahead for overtaking will be described below. For example, in normal travelling, overtaking frequently happens. In overtaking, especially in overtaking a very-large-size truck, in the related art, the alerting can merely be performed by using a loudspeaker, and if the ambient environment is complicated, or music or another sound inside the vehicle has a large volume, the vehicle ahead might not be able to be alerted, which causes a large hidden danger of the safety in driving. In an embodiment of the present disclosure, as shown in Fig. 5, when the overtaking has been just started, the steering pattern is projected in the direction of the vehicle that is intended to be overtaken, and it is projected in front of the current lane, i.e., the left front of the vehicle that is to be overtaken. When the two vehicles have travelled to the condition that the heads of the vehicles are parallel, a lane changing trajectory (i.e., the overtaking pattern) is projected, to alert the vehicle on the right the travelling intention of this vehicle, for it to prepare in advance.
[0059] As shown in Fig. 6, if, when the vehicle has been normally travelling to an intersection and requires to steer, and exactly now a pedestrian is passing in front through the intersection where the turning is to be made, at this point, in the related art, the steering cannot effectively be alerted to the pedestrian. The embodiments of the present disclosure can, according to the pedestrian information identified by the sensor, project the steering identifier under the feet of the pedestrian, and the pattern can flicker, which can effectively alert the pedestrian in front to timely avoid the vehicle.
[0060] The method for alerting by a vehicle according to the present disclosure can enable a pedestrian or an on-board person in a surrounding vehicle to accurately determine whether the vehicle is intending to steer or to overtake when turning on the turn light, whereby the vehicle or the pedestrian can timely know the travelling intention of the vehicle, so the vehicle or the pedestrian can be alerted, to improve the safety in driving.
[0061] Further, the method can determine the travelling intention when the turn light is not turned on, and, accordingly, the method can, if the vehicle requires to steer, project in advance the steering pattern onto the road surface in front of the vehicle, which, on one hand, alerts the driver of the vehicle to avoid missing the intersection due to the unfamiliarity of the road of the driver, and, on the other hand, alerts the other vehicles or pedestrians, to improve the safety in driving.
[0062] For example, the method may comprises, if the turn light has not been turned on, when, according to the navigation information and/or the image information of front of the vehicle, determining that the travelling intention of the vehicle is steering, projecting in advance the steering pattern onto the road surface in front of the vehicle, which, on one hand, alerts the driver of the vehicle to avoid missing the intersection due to the unfamiliarity of the road of the driver, and, on the other hand, alerts the other vehicles or pedestrians, to improve the safety in driving.
[0063] Fig. 7 is a structural block diagram of the system for alerting by a vehicle according to an embodiment of the present disclosure.
