Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In an embodiment of the present disclosure, the vehicle may be, for example: power-assisted electric vehicles, electric bicycles, balance cars, electric scooters, electric vehicles, and the like.
Fig. 1 is a flowchart illustrating a driving reminding method according to an exemplary embodiment, and as shown in fig. 1, the method includes the following steps:
in step S101, when it is detected that the driving speed of the vehicle is less than the preset speed threshold, the road condition information in front of the vehicle is acquired.
In one embodiment of the present disclosure, a sensor assembly (e.g., a vehicle speed sensor) in a vehicle may detect the travel speed of the vehicle in real time. Wherein the preset speed threshold value can be set according to the requirement, for example, set to 3 km/h.
In an embodiment of the present disclosure, the traffic information in front of the vehicle may include, for example: road obstacle information in front of the vehicle, a road type of a road on which the vehicle is currently traveling, intersection information in front of the vehicle, road marking information in front of the vehicle, and the like. Wherein the road obstacle information may include a distance between the vehicle and a pedestrian or other vehicle ahead of the vehicle; the road type of the current driving road may include: express way, main road, secondary road, branch road, path, etc.; the intersection information in front of the vehicle may include: whether an intersection (such as a crossroad) exists in front of the vehicle, the distance between the vehicle and the intersection in front, and the like; the road identification information in front of the vehicle may include: road traffic signs, road traffic markings, etc.
In the present disclosure, the road condition information in front of the vehicle may be acquired in different manners. Next, various ways of acquiring the road condition information in front of the vehicle will be described in detail through specific embodiments.
In a possible implementation manner, the image acquisition device can acquire the road condition image in front of the vehicle, and the road condition image is identified to acquire the road condition information in front of the vehicle. For example, a series of processing such as gray level transformation, smooth filtering, binarization, feature extraction and matching can be performed on the acquired road condition image, so that obstacles such as pedestrians and other vehicles in front of the vehicle are identified, and the distance between the vehicle and the obstacle in front is acquired according to the depth information of the road condition image. Road condition information such as intersection information and road identification information in front of the vehicle can be obtained through the acquired road condition images.
It should be noted that the image capturing device may be disposed on a vehicle (e.g., a wide-angle vehicle event data recorder installed on a windshield of the vehicle), or may be disposed on other terminal devices (e.g., a portable terminal such as a mobile phone of a driver of the vehicle).
In another possible implementation, the current geographic position of the vehicle may also be recorded by a positioning component (e.g., a GPS positioning device) built in the vehicle, and an inquiry request carrying the current geographic position is sent to a cloud server by the cloud server that establishes a communication connection with the vehicle, and the cloud server determines a current driving road of the vehicle from stored map data according to the current geographic position, inquires road condition information (e.g., road condition information in front of the vehicle, road identification information, etc.) in front of the vehicle on the current driving road, and returns the information to the vehicle.
In another possible implementation, a detection device (e.g., a radar) built in the vehicle may also be used to transmit a detection signal and receive an echo signal of the detection signal after reflection, and the road condition information may be obtained according to the detection signal and the echo signal. For example, the distance between the vehicle and the obstacle in front of it can be determined from the time interval between the emission instant of the probe signal and the reception instant of the echo signal and the propagation speed of the emitted signal in the air.
In step S102, it is determined whether the traffic information in front of the vehicle satisfies a predetermined condition.
The vehicle needs to keep a certain safety distance from pedestrians, other vehicles, etc. during driving, and needs to pay special attention to pedestrians, vehicles, etc. suddenly appearing in the field of view when driving on a small road or preparing to pass through an intersection, a pedestrian crossing, etc., and thus, the preset conditions may be set accordingly. Specifically, when the road obstacle information in front of the vehicle indicates that an obstacle (such as a pedestrian or other vehicle) exists in a first preset range in front of the vehicle, it may be determined that the road condition information in front of the vehicle meets a preset condition; or, when the road type of the current driving road of the vehicle is a preset road type (such as a small road), it may be determined that the road condition information in front of the vehicle meets a preset condition; or when the intersection information in front of the vehicle indicates that the intersection exists in a second preset range in front of the vehicle, determining that the road condition information in front of the vehicle meets the preset condition. The first preset range and the second preset range may be set as required, for example, the first preset range may be set as a circular area with a vehicle as a center and a radius of 10m, and the second preset range may be set as a circular area with a vehicle as a center and a radius of 30 m.
In step S103, when the traffic information in front of the vehicle satisfies the preset condition, the warning information is output.
When the road condition information in front of the vehicle meets the preset conditions, the safety accidents easily occur due to the fact that the road condition in front of the vehicle is complex, and at the moment, the warning information can be output to prompt pedestrians and other drivers in front of the vehicle to notice avoidance. The form of the warning message may include a sound, a light, or a combination of the two, which is not limited in this disclosure.
By the driving reminding method, when the driving speed of the vehicle is detected to be smaller than the preset speed threshold value and the road condition information in front of the vehicle meets the preset conditions, the warning information is output to remind a pedestrian or other vehicle drivers in front of the vehicle to avoid, so that the vehicle can output the warning information only under the necessary condition, and the interference of the warning information to the pedestrian and other drivers is reduced.
In another exemplary embodiment of the present disclosure, as shown in fig. 2, the method further includes:
in step S104, when the road condition information does not satisfy the preset condition, the output of the warning information is stopped.
After the warning information is output, the road condition information in front of the vehicle can be obtained in real time, and when the road condition information in front of the vehicle is detected not to meet the preset condition, the warning information is stopped being output, so that the situation that the warning information is continuously output to pedestrians and other vehicle drivers and the like to cause interference is avoided.
