Description

[Technical field]

[0001] The present invention relates to the technical field of safe driving of automobiles, and in particular to a safe driving support system for new energy automobiles. [Background technology]

[0002] With the development of vehicle technology, more and more people are traveling by car. When driving, drivers may not be able to concentrate or may become careless, leading to the vehicle straying from the lane and causing accidents such as collisions and rear-end collisions. Therefore, lane departure warning systems have been developed, which can effectively reduce the driver's fatigue when the vehicle is traveling at high speed.

[0003] A conventional lane departure warning system will prompt the driver to make road corrections by sound or vibration of the steering wheel when it determines that the vehicle is about to depart from the target lane. However, when the driver needs to make a normal lane change, the vehicle warning will affect the driver's vehicle operation. In addition, when the vehicle is traveling at high speed, the constant sound or steering wheel vibration warning time may not be enough for the driver to timely correct the road, which may even cause an accident and damage to the vehicle and passengers. Therefore, a safe driving support system for new energy vehicles is proposed to solve the above problems. Summary of the Invention [Problem to be solved by the invention]

[0004] The objective of the present invention is to propose a safe driving support system for new energy vehicles to solve the shortcomings existing in the prior art. [Means for solving the problem]

[0005] In order to achieve the above object, the present invention employs the following technical means.

[0006] A new energy vehicle safe driving support system including a control unit, a vehicle capture module bidirectionally connected to the control unit, a speed monitoring module, and a data processing module, wherein the control unit collects road image sequences, and sequentially performs gradation, filtering, and binarization processes on each collected frame image to extract lanes, an axis line acquisition module acquires the axis line of the vehicle and identifies the position of the vehicle within the lane, a warning module and a turn signal lamp module alarm when the vehicle deviates when the turn signal lamp is turned off, and times the alarm time of the warning module, and realizes vehicle capture by cooperating with the speed monitoring module.

[0007] In a preferred embodiment of the present invention, the data processing module is for receiving data collected by the image collection unit and the center axis acquisition module, calculating the distance between the center axis and both lane boundary lines, and comparing it with a set threshold value.

[0008] In a preferred embodiment of the present invention, the vehicle interdiction module is an automated vehicle driving system for interdicting a vehicle that has wandered out of its lane so as to provide the driver with more time to correct the deviation from the travel lane.

[0009] In a preferred embodiment of the present invention, the setting threshold in the speed monitoring module is 60km / h, and the setting threshold in the timing module is 2s, and when the vehicle speed is greater than 60km / h, the vehicle will be automatically impounded in 2s.

[0010] In a preferred embodiment of the present invention, the vehicle further includes a route planning unit bidirectionally connected to the control unit, and the route planning unit plans a driving route at an intersection when the vehicle deviates from its lane, virtually docks with an oncoming lane, and generates a target route.

[0011] In a preferred embodiment of the present invention, the route planning unit is provided with a map positioning module therein for acquiring vehicle position information.

[0012] In a preferred embodiment of the present invention, the vehicle further includes a display module mounted on a central control panel of the vehicle for displaying the vehicle's driving position, lane markings, and the vehicle's center line.

[0013] In a preferred embodiment of the present invention, the warning module is a sound announcer or a vibration motor mounted inside the steering wheel. In a preferred embodiment of the present invention, when traveling on a road having lanes, the monitoring steps include: S1, collecting a road image sequence as meta data, and sequentially performing gradation, filtering and binarization processes on each collected frame image to extract lane boundary lines; S2, obtaining the vehicle axis line, calculating the distance between the vehicle axis line and both lane boundary lines and comparing it with a distance threshold; S3, issuing an alarm to the driver via a warning module if the distance threshold is exceeded and no signal to turn on the vehicle's turn signal lamp is received; and S4, seizing the vehicle and turning on the autonomous driving mode if the driver does not correct the vehicle deviation after a certain period of warning.

[0014] In one preferred embodiment of the present invention, when traveling through an intersection that does not have lanes, the monitoring steps include: S1, collecting a road image sequence, and sequentially performing gradation, filtering, and binarization on each collected frame image to extract lane boundaries, virtually extend the existing lane boundaries, and dock them with the oncoming lane; S2, obtaining a vehicle center axis, calculating the distance between the vehicle center axis and the virtual lane boundaries on both sides, and comparing it with a distance threshold; S3, if the distance threshold is exceeded and a signal to turn on the vehicle's turn signal lamp is not received, issuing an alarm to the driver via a warning module; and S4, if the driver does not correct the deviation of the vehicle after a certain period of warning, seizing the vehicle and turning on the autonomous driving mode. Effect of the Invention

[0015] 1. In the present invention, when a vehicle is changing lanes normally, the data processing unit identifies whether the turn signal lamp is on. If the turn signal lamp is on, the warning module is turned off to avoid warning when the vehicle is changing lanes normally, and facilitates the driver to control the normal operation of the vehicle. 2. When the warning module is activated, the device's speed monitoring module and timing module will work together to determine the time for vehicle seizure. If the vehicle speed is higher than 60km / h, the vehicle will be automatically seized within 2 seconds and the vehicle will be slowed down, giving the driver more time to correct lane departure and reduce the occurrence of accidents. 3. When a vehicle enters an intersection and cannot monitor the lanes, the present invention can virtually extend the existing lane and make it merge with the oncoming lane before the vehicle leaves the lane boundary, which is convenient for warning whether the vehicle is leaving the lane at an intersection without lane boundary.

[0016] As described above, the present invention warns the driver of lane departure only when the turn signal lamp is off, facilitating the driver to operate the vehicle normally; at the same time, on roads with lanes and intersections without lanes, the vehicle can be seized within a certain period of time when it deviates from the lane, providing the driver with more time to correct the lane departure, and effectively reducing the occurrence of unintentional lane departure accidents caused by driver fatigue, carelessness, etc. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Hereinafter, the technical aspects of the embodiments of the present invention will be clearly and completely described with reference to the drawings in the embodiments of the present invention. However, obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] As shown in Fig. 1-2, the new energy vehicle safe driving support system includes a control unit, a vehicle capture module bidirectionally connected to the control unit, a speed monitoring module, and a data processing module. The vehicle capture module is an automatic vehicle driving system for capturing a vehicle that has run out of a lane so as to provide the driver with more time to correct the deviation from the driving lane, and the vehicle capture module captures a vehicle that has unintentionally run out of the lane, thereby reducing vehicle accidents. The control unit circumscribes an image collection unit, a center axis acquisition module, a warning module, a turn signal lamp module, and a timing module. The image collection unit is a 360° panoramic camera, which collects a road image sequence, and each collected frame image is used to perform gradation, filtering, and binarization processing in sequence to extract lanes, and further includes a display module mounted on the central control panel of the vehicle for displaying the vehicle's driving position, lane boundary lines, and the center axis line of the vehicle.

[0020] The center axis acquisition module is used to acquire the center axis of the vehicle and identify the position of the vehicle within the lane, and the data processing module is used to receive the data collected by the image collection unit and the center axis acquisition module, calculate the distance between the center axis and the lane boundary lines on both sides, and compare it with a set threshold, the threshold being half the distance between the lanes on both sides.

[0021] In the warning module and turn signal lamp module, the warning module issues an alarm when the vehicle deviates from the normal course when the turn signal lamp is turned off, thereby reducing the impact on the driver. The warning module is an audio announcer or a vibration motor mounted inside the steering wheel, and issues a warning to the driver when the vehicle deviates from the normal course by audio announcement or by vibrating the turn signal lamp.

[0022] The timing module is used to measure the alarm time of the warning module, and cooperates with the speed monitoring module to realize vehicle impoundment, where the setting threshold of the speed monitoring module is 60km / h, the setting threshold of the timing module is 2s, and when the vehicle speed is greater than 60km / h, the vehicle is automatically impounded in 2s.

[0023] The vehicle control system further includes a route planning unit bidirectionally connected to the control unit, which plans a driving route at an intersection when the vehicle deviates from a lane, virtually docks with an oncoming lane, and generates a target route. A map positioning module is provided inside the route planning unit to obtain position information of the vehicle. Working Example

[0024] When monitoring whether the vehicle deviates from the lane, first, the image collection unit collects a road image sequence, and each collected frame image is processed by gradation, filtering and binarization in order to extract the lane. At the same time, the center axis acquisition module acquires the center axis of the vehicle, calculates the distance between the center axis of the vehicle and the lane boundary lines on both sides, and compares it with the distance threshold. If the distance threshold is exceeded and the signal to turn on the turn signal lamp of the vehicle is not received, the warning module issues a warning to the driver. If the driver does not correct the vehicle deviation after a certain period of warning, the vehicle is seized and the automatic driving mode is turned on. It provides the driver with more time to correct the lane deviation, effectively reducing the occurrence of unintentional lane deviation accidents caused by driver fatigue, carelessness, etc. When driving to an intersection, before the vehicle deviates from the lane, the existing lane is virtually extended and docked with the oncoming lane, which is convenient for warning whether the vehicle is deviating from the road at an intersection without lanes; on roads with lanes and intersections without lanes, the vehicle can be seized within a certain period of time while it is deviating from the lane, providing the driver with more time to correct the lane deviation, effectively reducing the occurrence of unintentional lane deviation accidents caused by driver fatigue, carelessness, etc.

[0025] The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Within the disclosed technical scope of the present invention, any technician who makes equivalent substitutions or modifications based on the technical solutions of the present invention and the concept of the invention should be included in the protection scope of the present invention.
