Existing road traffic is complex, for example, vehicles often have the need to traverse narrow and curved road segments during travel. For example, a narrow road in a rural area. When a road has pedestrians on one or both sides, the field of view is disturbed, especially by novice drivers. For example, when the road curves to the right and there is a pedestrian in front of the left of the vehicle, the driver's field of vision may be disturbed in two ways, and the road condition in front of the right of the vehicle may be lost due to the hood obstruction. Secondly, the driver can preferentially choose to pay attention to the pedestrian in the front left at any time so as to avoid colliding with the pedestrian, and therefore the driver neglects the road condition in the front right of the vehicle. Under the influence of the two aspects, the right front wheel of the vehicle is easy to run out of the edge of the road, so that the condition that the vehicle holds the bottom is caused. The existing driving safety system cannot effectively deal with the situations, so that the application aims to provide the driving safety system capable of overcoming the defects.

Detailed Description

The invention will be further described with reference to the accompanying drawings, without limiting the scope of the invention to the following:

example 1

As shown in fig. 1 and 2, the present application provides a driving safety system including at least a rearview assembly 100 and a display assembly 200. The rearview assembly 100 includes at least a first rearview assembly 1 and a second rearview assembly 2. The first rearview assembly 1 is adapted to be mounted to a first side of a vehicle to facilitate a driver's view of a first environmental condition of the first side of the vehicle. The second rearview assembly 2 is adapted to be mounted to a second side of the vehicle to facilitate a driver's view of a second environmental condition of the second side of the vehicle. The display assembly 200 is installed in the cab to facilitate the driver to observe a third environmental state directly behind the vehicle. The first rear view assembly 1 and the second rear view assembly 2 are both connected to the vehicle by means of separate drive assemblies 4. A control assembly 5 is provided in the vehicle, the control assembly 5 being communicatively coupled to the drive assembly 4. The driver can manually control the driving assembly 4 to work through the control assembly 5, and then the state of the first rear-view assembly 1 and/or the second rear-view assembly 2 is changed. For example, when the driver needs to adjust the field of view of the first rearview assembly 1, the control assembly 5 can send a control command to the driving assembly 4, and the driving assembly 4 can change the state of the first rearview assembly 1 after generating corresponding actions. Or the control unit 5 may automatically send a control command to the drive unit 4 according to a predetermined program set therein. For example, when the control assembly 5 detects that the vehicle is turned off, it automatically sends a control command to the driving assembly 4, and the first and second rearview assemblies 1 and 2 will be switched from the folded state to the unfolded state.

Preferably, each of the first and second rearview assemblies 1 and 2 includes at least a housing 1a and a mirror body 1 b. The mirror bodies 1b are all arranged in the shell 1a, the driving assembly 4 is arranged on a vehicle, the driving assembly 4 is coupled to the mirror bodies 1b, and when the driving assembly 4 works, the driving assembly can drive the mirror bodies 1b to generate form changes such as left-right rotation, up-down rotation and the like, so that the purpose of changing the visual field range of the mirror bodies 1b is achieved. Display assembly 200 includes at least a display 3a, a second image collector 3b and a first image collector 3 c. First image capturer 3c and second image capturer 3b are each communicatively coupled to display 3 a. The first image collector 3c is disposed on the housing 1a and is configured to collect first environmental status data around the vehicle. The second image collector 3b is configured to collect second environmental status data behind the vehicle. The first environmental status data and the second environmental status data may be real-time image data. The display 3a is capable of receiving the first environmental status data and the second environmental status data and visually displaying them.

Preferably, the first environmental status data includes at least image data of a left front wheel of the vehicle and a right front wheel of the vehicle. Image data of the left front wheel of the vehicle can be acquired by the first image acquirer 3c of the first rearview assembly 1. Image data of the right front wheel of the vehicle can be captured by the first image collector 3c of the second rearview assembly 2. The first and second rearview assemblies 1 and 2 further include a radar detector 1 d. The radar detector 1d is used to detect whether an obstacle exists within a set distance in front left and right of the vehicle. In the case where the radar detector 1d detects that an obstacle exists in the front left and/or right of the vehicle, the first image collector 3c transmits image data of the front left wheel and/or the front right wheel of the vehicle to the display 3a for display. The display 3a may have at least two display areas, different display areas being used for displaying different image data. For example, the left display area is used to display the image data of the left front wheel, and the right display area is used to display the image data of the right front wheel.

Preferably, in the case that it is detected that an obstacle exists on the left front side and/or the right front side of the vehicle, the rearview assembly 100 collects environmental status data of vehicle wheels and transmits the environmental status data to the display assembly 200 for display, wherein in the case that the vehicle wheels at least include a left front wheel and a right front wheel of the vehicle, the display assembly 200 displays the different environmental status data in a manner of having a priority level, so as to reduce the environmental status data that a driver needs to pay priority attention to in the case that the vehicle has a safety hazard. Specifically, the display 3 is configured to display image data as follows:

s1, the display 3a preferentially displays the image data of the front right wheel of the vehicle when the radar detector 1d detects that an obstacle is present on the front left wheel of the vehicle, or the display 3a preferentially displays the image data of the front left wheel of the vehicle when the radar detector 1d detects that an obstacle is present on the front right wheel of the vehicle.

Specifically, the priority display may be implemented by a single display, a display performed before the time is advanced, a side-by-side highlight display, or the like. For example, when there is an obstacle in the left front of the vehicle, the display 3 may display the image data of the right front wheel alone, or may display both the image data of the right front wheel and the image data of the left front wheel, and at this time, the image data of the right front wheel is displayed with priority, and the image data of the left front wheel is displayed after the image data of the right front wheel has been displayed for a set time of, for example, 3 seconds. Or the image data of the right front wheel is highlighted in a highlighted manner. Vehicles often have a need to traverse narrow and curved road sections during travel. For example, a narrow road in a rural area. When a road has pedestrians on one or both sides, the field of view is disturbed, especially by novice drivers. For example, when the road curves to the right and there is a pedestrian in front of the left of the vehicle, the driver's field of vision may be disturbed in two ways, and the road condition in front of the right of the vehicle may be lost due to the hood obstruction. Secondly, the driver can preferentially choose to pay attention to the pedestrian in the front left at any time so as to avoid colliding with the pedestrian, and therefore the driver neglects the road condition in the front right of the vehicle. Under the influence of the two aspects, the right front wheel of the vehicle is easy to run out of the edge of the road, so that the condition that the vehicle holds the bottom is caused. This application is when using, and the image data of right front wheel passes through display 3a and demonstrates for the driver directly perceivedly, and the driver only needs adjust the position of right wheel according to the image data of the right front wheel of vehicle right this moment, avoids the right wheel to roll off road border, because road width can satisfy the automobile body usually and a small amount of pedestrian is parallel, consequently, the driver only needs to guarantee that the right front wheel does not roll off road border and then can ensure that the pedestrian of left front side can not be collided to the left front wheel. In the process, most of the attention of the driver is concentrated on the right front wheel, the problem of distraction of the driver cannot occur, and the driving safety can be improved.

S2, when the radar detector 1d detects that there is an obstacle on both the left and right front sides of the vehicle, the radar detector 1d determines a first real-time distance between the obstacle on the left front side of the vehicle and a second real-time distance between the obstacle on the right front side of the vehicle and the vehicle, and when the first real-time distance is smaller than the second real-time distance, the display 3a displays image data on the right front wheel of the vehicle, or when the first real-time distance is larger than the second real-time distance, the display 3a displays image data on the left front wheel of the vehicle. Specifically, when the driver drives the vehicle across the width-limited road, the radar detector 1d detects that an obstacle exists on both the front left side and the front right side of the vehicle. In the prior art, the image data of the periphery of the vehicle is generally displayed to the driver, and the attention of the driver is excessively dispersed. When the vehicle width limiting device is used, the width of the width limiting road is larger than that of a vehicle, and whether the vehicle can safely drive through the width limiting road can be judged only by observing the state of the side of the vehicle. Therefore, when the first real-time distance is smaller than the second real-time distance, the image data of the right front wheel of the vehicle is displayed to remind the driver of driving to the right, and then the driver only needs to observe the image data of the right front wheel of the vehicle all the time, so that the driver can safely pass through the width-limited road. Through the above setting mode, can reach following technological effect at least: first, through the image data that display 3a shows, the driver drives the vehicle and moves towards corresponding one side in advance, and then avoids appearing and producing the risk of colliding with the too little distance from the barrier. For example, when the display displays the image data of the right front wheel, the display is moved to the right side. Alternatively, when the display displays the image data of the left front wheel, the display is moved to the left side. In the driving process, a driver only needs to keep track of image data of one side of the vehicle all the time, and therefore the situation that the attention of the driver is dispersed can be avoided.

Example 2

This embodiment is a further improvement of embodiment 1, and repeated contents are not described again.

Preferably, the radar detector 1d is configured to be able to collect environmental state data around the vehicle to determine whether an obstacle is present around the vehicle. For example, the radar detector 1d can be provided on a roof of a vehicle, which can emit sound waves to the surroundings to enable detection of an obstacle. In the case where the radar detector 1d detects that an obstacle exists around the vehicle, the radar detector 1d can determine the state of the obstacle. The state of the obstacle may include, but is not limited to, a stationary state and a moving state. Specifically, when the vehicle is in a stationary state, the radar detector 1d can monitor the distance between the vehicle and the obstacle in real time, and when the distance remains unchanged, it is determined that the obstacle is in the stationary state, and when the distance changes, it is determined that the obstacle is in a moving state. When the vehicle is in a moving state, the radar detector 1d can monitor the distance between the vehicle and the obstacle in real time, judge that the obstacle is in a stationary state when the distance keeps increasing or decreasing at a substantially constant speed, and judge that the obstacle is in a moving state when the distance increases or decreases at an uneven speed.

Preferably, in a case where the radar detector 1d detects that a moving object is present around the vehicle and the real-time distance of the moving object from the vehicle gradually decreases, the radar detector 1d determines whether the moving object has a collision tendency with the vehicle. Specifically, if the real-time distance between the moving object and the vehicle gradually decreases, it indicates that the moving object is approaching the vehicle, and at this time, the radar detector 1d can acquire the speed of the moving object relative to the vehicle, and when the real-time distance between the moving object and the vehicle is smaller than a first set threshold value and the speed of the moving object relative to the vehicle is greater than a second set threshold value, it can be determined that there is a collision tendency between the moving object and the vehicle. For example, in a normal state, when the vehicle is at a speed of 100Km per hour, the limit braking distance is 900 to 1000m, and when the distance between the vehicle and the moving object is less than 900m and the speed per hour of the vehicle is greater than 100Km, the vehicle immediately brakes and cannot avoid collision with the moving object, in this case, the first set threshold may be 900m, and the second set threshold may be 100 Km/h. The radar detector 1d can determine the azimuth angle of the moving object with respect to the vehicle, and thus confirm the collision position. For example, when the moving object is located behind the vehicle, the collision location may be the rear of the vehicle. In the case where the moving object has a collision tendency with the vehicle, the display assembly 200 is configured to display a collision site, and the rearview assembly 100 is turned on in advance to acquire image data of the collision site. The existing vehicle usually collects images of an area in front of the vehicle by installing a vehicle-mounted automobile data recorder, and the automobile data recorder can record image data of a left front cover and a right front cover of the vehicle, for example, the image collecting area is limited, and further the following problems exist: 1. when the parts which cannot be monitored by the automobile data recorder collide, the liability determination difficulty is increased due to the lack of necessary image evidence. 2. When a vehicle collision occurs, it is usually necessary to stop the vehicle immediately to record the situation of the first accident site, and at this time, some of the offenders may have behaviors maliciously destroying the first accident site, for example, the offender still continues to travel a short distance when the collision occurs, so that the first accident site is destroyed, and the difficulty of determining the blame is further increased. The first image collector 3c and the second image collector 3b may be 360 ° panoramic image collectors, and the first image collector 3c may collect images of all areas of the front side, the left side, the right side, and the like of the vehicle. An image of the rear region of the vehicle can be captured by the second image capture device 3 b. When the vehicle collision monitoring system is used, the image video data of the vehicle collision position can be collected and stored through the first image collector 3c and the second image collector 3b, and then the whole process of collision can be recorded. Through the mode, at least the following technical effects can be achieved: the driver can observe the damage condition of the collision part in the vehicle, the vehicle damage condition can be directly evaluated, the collision occurrence process is recorded, when the hit-and-run vehicle escapes, the driver can drive the vehicle to a safe position and then park the vehicle, secondary traffic accidents caused by the fact that the vehicle is damaged are prevented from getting off and the road jam degree caused by the traffic accidents can be reduced. In addition, the display assembly 200 displays the image data of the collision part in real time, so that the driver can implement some risk avoiding operations in advance to avoid collision, and further the purpose of active risk avoidance is achieved. The three image data of the collision part are recorded and stored, so that a basis can be provided for judging traffic responsibility in the later period, and the purpose of reducing responsibility determination difficulty is achieved.

Preferably, in the case where the moving object has a collision tendency with the vehicle, the rearview assembly 100 is further configured to:

and S1, synchronously acquiring driving operation data of the driver and characteristic data of the moving object, wherein the driving operation data at least comprises image data operated by the driver and vehicle driving parameter change data caused by the operation of the driver, and the characteristic data at least comprises identity data of the moving object and moving state data of the moving object.

Specifically, the driving operation data of the driver includes at least image data of the driver's operation and vehicle running parameter variation data caused by the driver's operation. For example, rearview assembly 100 also includes a third image collector 6. The third image collector 6 may be disposed in the cab, and it may collect at least the hand motion of the driver. The vehicle driving parameter variation data includes, but is not limited to, variation data of a driving speed of the vehicle, variation data of a driving route. For example, a GPS positioning module may be provided on the vehicle, and the running speed and the running route of the vehicle can be monitored and recorded in real time through the GPS positioning module. When the driver performs a risk avoidance operation such as braking, acceleration, lane change, turning, etc. according to the image data of the collision portion displayed by the display assembly 200, the third image collector 6 can collect and record the action of the driver when performing the risk avoidance operation. The change of the driving speed after braking or acceleration and the change of the driving route after lane changing or turning can be recorded by the GPS positioning module.

Preferably, the characteristic data includes at least identification data of the moving object and movement state data of the moving object. The identification data of the moving object may be a face image (when the moving object is a pedestrian) and a license plate image (when the moving object is a vehicle). The moving state data of the moving object is used for representing the moving state of the moving object, and includes, but is not limited to, speed, motion state and the like of the moving object. For example, when the vehicle runs in the reverse direction, the running state thereof is the reverse direction. When the vehicle runs across the road, the motion state of the vehicle is the road-crossing driving. When the vehicle turns around, the motion state is the turning around driving. When the vehicle is running at a rapid deceleration, the running state is the deceleration running. That is, when a collision occurs, the state of the moving object can be monitored through the moving state data, so that whether the moving object has an illegal driving behavior or not can be conveniently judged. Through the above setting mode, can reach following technological effect at least: when a traffic accident occurs, the hit-and-run vehicle escapes, and the problem that the hit-and-run vehicle cannot find the hit-and-run vehicle can be avoided by collecting the identity data of the moving object. In the case of a collision, the driver's operation and the moving state of the causing vehicle can be recorded, and further, detailed evidence for assignment division can be provided, and the efficiency of assignment processing can be improved.

S2, matching time labels for the driving operation data and the feature data so that the driving operation data and the feature data are in the same time dimension.

Specifically, the time tag is used for representing the generation time of the driving operation data and the characteristic data, and the driving operation data and the characteristic data can be ensured to be in the same time dimension by matching the time tag. For example, existing tachographs and in-vehicle displays often suffer from time mismatch. That is, the time displayed by the drive recorder and the time displayed by the in-vehicle display are different from each other. The driving operation data is generated by the driver after performing the driving operation. The feature data is generated by the movement of the moving object. By matching the time labels with the driving operation data and the characteristic data, the states of the driver and the moving object at the same time can be determined, and the problem that the driving operation data and the characteristic data are disordered and cannot be used as a basis for determining responsibility can be avoided.

Preferably, the driving safety system further comprises an acousto-optic reminder 6. The acousto-optic alarm 6 is coupled to the radar detector 1 d. In the case that the radar detector 1d determines that the moving object and the vehicle have a collision trend, the radar detector 1d sends a control command to the acousto-optic reminder 6 to remind the surrounding of the vehicle. Specifically, a chain rear-end collision often occurs on a highway, and the root causes of the chain rear-end collision are as follows: too small following distance, too fast speed, too late time for finding the following car, and the like. For example, A, B, C three vehicles travel in sequence at a certain distance. When A brakes suddenly, the driver of the B vehicle does not find the sudden braking condition of the A vehicle in time, so that the B vehicle and the A vehicle are in rear-end collision. In the process of rear-end collision, the vehicle B finds that the deceleration time of the vehicle A is too late, and at the moment, the vehicle B reminds the rear vehicle of being too late by stepping on a tail lamp when braking, so that the risk degree of rear-end collision between the vehicle C and the vehicle B is improved. This application is when using, when B car detects to have the collision trend with A car, then reminds the C car through reputation reminiscences 6 immediately, owing to remind the time in advance for the C car has sufficient reaction time, and then can avoid the C car to take place to knock into the back with the B car.

Preferably, in the case of detecting that an obstacle exists on the left front side of the vehicle, the driving assembly 4 controls the first rearview assembly 1 to be switched from the unfolded state to the folded state, and the rearview assembly 100 collects the environmental state data to be transmitted to the display assembly 200 for display. When two vehicles are staggered in opposite directions, the left first rearview component 1 is switched to a folded state from an unfolded state, more staggered space can be vacated, meanwhile, the first image collector 3c collects the position image of the right front wheel, and the first image collector 3c collects the position image of the left front wheel and displays the position image of the left front wheel through the displayer 3 a. The display 3a may be located on the right side of the driver, where the user's head only needs to be held in the right twist to see all the states. By the mode, the problem that the difficulty of the wrong vehicle is increased due to repeated observation of the driver left and right when the wrong vehicle is driven can be avoided.

Preferably, when it is detected that an obstacle exists on the rear side of the vehicle in the night driving state and the distance between the obstacle and the vehicle is smaller than a set value, the driving assembly 4 operates to adjust the included angle α between the mirror body 1b and the vehicle, so that the distance between the boundary of the area that can be observed by the mirror body 1b and the vehicle can be increased. When driving at night, when the rear vehicle is too close to the front vehicle, the light of the rear vehicle is easily transmitted to the eyes of the driver through the mirror body, so that the dazzling condition is caused, the driver is very uncomfortable, and the risk degree of safety accidents is increased. When the glasses are used, the included angle alpha between the glasses body 1b and a vehicle can be increased, and light does not dazzle a driver any more. Meanwhile, when the rear vehicle changes lane and overtakes, the distance between the regional boundary of the visual field of the mirror body 1b and the vehicle is increased, so that a driver can see the lane changing condition of the rear vehicle in time, and the driving safety degree is further improved.

Example 3

This embodiment is a further improvement of the foregoing embodiment, and repeated contents are not described again.

Preferably, the display module 200 is able to process the environmental state data to generate a driving strategy, which is able to act on the vehicle to change at least the driving direction and the driving speed of the vehicle, wherein, in case the driver inputs a first control command for changing the driving direction and/or the driving speed according to the environmental state data, the display module 200 is able to modify the first control command according to the driving strategy, such that the first control command can be suppressed or gained. Specifically, the data such as the real-time distance and the relative speed between the vehicle and the surrounding object can be acquired through the environmental state data. The driving strategy aims to avoid collision of the vehicle with objects in its surroundings. For example, when the vehicle is running on a highway, it can detect the real-time distance and the relative speed with the preceding vehicle, when the real-time distance is less than the set threshold value and the relative speed is greater than the set threshold value, the vehicle and the preceding vehicle will generate a collision risk, and at this time, the generated running strategy may be to reduce the vehicle speed or change lanes. The generated driving strategy may be transmitted to, for example, an ECU driving computer of the vehicle through the display module 200 to directly act on a deceleration system or a steering system of the vehicle. When the driver judges that the vehicle and the front vehicle have collision risks according to the environmental state data, the driver can input a first control command in the modes of stepping on a brake or an accelerator, rotating a steering wheel and the like so as to achieve the purpose of changing the driving direction and the driving speed of the vehicle. However, most drivers with new hands have insufficient driving experience, and the problems that sudden braking of the vehicle is caused by overlarge stepping brake force or the vehicle is turned over due to overlarge rotation angle of the steering wheel and the like can occur. In this case, the driving strategy can correct the first control command. The first control command being suppressed means that the output feedback it produces is attenuated. The first control command is gained in the sense that the output feedback it produces is enhanced. For example, the first control command input by the driver generates output feedback that the steering wheel is rotated by 90 °, and the rotation angle of the steering wheel may be reduced to, for example, 70 ° after the first control command is suppressed by the driving strategy, or may be increased to, for example, 100 ° after the first control command is gained. Through the mode, the measures of the novice driver during emergency treatment can be corrected, so that the aim of improving the driving safety is fulfilled.

Preferably, in the case where the driving strategy includes at least two operational instructions that can be executed, the display component 200 can sort the at least two operational instructions based on the environmental state data to determine a priority level of execution, and the at least two operational instructions can be displayed distinctively by the display component 200 based on the priority level, wherein the operational instructions can be executed in a suppressed manner to automatically act on the vehicle in the case where the first control command is not input by the driver, or the operational instructions can modify the first control command in the case where the first control command is input by the driver. In particular, the implementation of a driving strategy usually requires the implementation of multiple operators to be fully implemented. For example, when the vehicle travels in the middle lane of the bidirectional three lanes, if the vehicle and the front vehicle have a rear-end collision risk, the travel strategy is to change lanes. At this time, the lane change may be divided into, for example, a first operation command to turn on the turn signal, a second operation command to decelerate or accelerate, a third operation command to turn the steering wheel, a fourth operation command to return the steering wheel to the normal position, and the like. The display assembly 200 is capable of determining whether a vehicle is present on the rear left and right sides of the vehicle, the speed of the vehicle, the real-time distance, etc., based on the environmental status data, and thus, for example, the exact value of turning on the left or right turn signal, adjusting the speed of the vehicle, the steering wheel rotation angle. Subsequently, the display component 200 can determine a priority level of the operation instruction. For example, the priority of the third operation instruction is larger than the second operation instruction when the left rear side vehicle is at a longer distance from the traveling vehicle, or the priority of the third operation instruction is smaller than the second operation instruction when the left rear side vehicle is at a shorter distance from the traveling vehicle. Through the mode, the driver can correspondingly input the first control command according to the priority level of the operation instruction so as to realize corresponding operation. For example, the turn signal lamp deflector rod can be moved to turn on the turn signal lamp, a novice driver can be guided to execute correct emergency operation through the guidance of the driving strategy, and meanwhile, the driving strategy can correct the operation of the driver so as to achieve the aim of driving safety. Further, in a case where the driver does not input the first control command, the operation instruction can be executed to automatically act on the vehicle in a suppressed manner. For example, when the vehicle is running on a highway, the vehicle may be in a constant-speed cruise mode, the driver is inattentive to result in a risk of a frontal collision that he ignores, at which time the operation command can be executed. When the vehicle is executing the operation command, the driver may suddenly wake up to execute the first control command to avoid the collision, and the superposition of the first control command and the execution of the operation may cause excessive feedback, for example, an excessive increase in the vehicle speed, resulting in the occurrence of an accident. In the application, the operation command is restrained, and the phenomenon that the operation command is overlapped with the first control command to form overlarge feedback can be avoided.
