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.
It should be noted that all actions of acquiring signals, information or data in the present application are performed under the premise of complying with the corresponding data protection regulation policy of the country of the location and obtaining the authorization given by the owner of the corresponding device.
When more than two vehicles arrive continuously at the side rear part of the vehicle, the early warning system in the related art can not distinguish and early warn one vehicle. When a relatively close vehicle drives away from a collision risk area, a driver may think that there is no danger and an emergency lane change occurs, or a passenger may think that there is no danger and an emergency door opening occurs, which is highly likely to cause a traffic accident. In view of this, the inventor thinks of a vehicle early warning method, which can prompt for multi-target approach behind a vehicle.
FIG. 1 is a flow chart illustrating a vehicle warning method according to an exemplary embodiment. Referring to fig. 1, the method includes the following steps.
In step S11, the moving object behind the vehicle is monitored.
Fig. 2 is a diagram illustrating a scenario of monitoring a moving object according to an exemplary embodiment. As shown in fig. 2, the vehicle a is a vehicle, and there are two vehicles (vehicle B and vehicle C) in front and rear in a predetermined range (within a dashed line frame) in the rear left of the vehicle a. When the driver or the left passenger of the vehicle a opens the door while the vehicle a is parked at the roadside, the vehicle a easily collides with the vehicles B and C. In the related art, only one vehicle is monitored, but not two vehicles, and when the vehicle B is driven away from the vehicle a, the passenger may assume that there is no vehicle, and it is dangerous to open the door.
Specifically, a moving object (e.g., a vehicle) behind can be monitored using a speed sensor, a distance sensor, or the like mounted outside the vehicle. The monitoring may be performed using millimeter wave radar, for example. Millimeter wave radars are particularly sensitive to the radial velocity of a target, and can accurately distinguish rear moving objects with different velocities (relative to the speed of the vehicle) by using ultrahigh Doppler resolution. For example, the radar may determine the number of moving objects from a different plurality of velocities determined from the return signals. And multiple vehicles behind can be determined by utilizing an image intelligent identification technology, the speed of each vehicle is obtained, and data obtained by monitoring different sensors are fused to obtain the final speed of the vehicle behind.
It will be understood by those skilled in the art that the speed referred to in the present embodiment, without specific reference, is a relative speed with respect to the speed of the vehicle.
In step S12, when it is detected that at least two moving objects approach the vehicle, a first prompt message indicating that there is a multiple object approach is output.
The first prompt message may be a light, a flashing light, a voice, a beep, etc. For example, outputting the first prompting message may include one or more of: controlling an indicator light on the outer rearview mirror to light or flash; an indicator light on the door handle is controlled to light up or flash; the first audio message is output.
According to the technical scheme, the moving objects behind the vehicle are monitored, and when at least two moving objects are monitored to be close to the vehicle, a first prompt message for indicating that multiple targets are close is output. Thus, the driver or the passenger can know the number of the rear moving objects according to the first prompt message indicating that the multiple objects are close to the vehicle, so that necessary measures can be actively taken, accidents caused by the fact that the rear moving objects are close to the vehicle are avoided, and driving safety is improved.
FIG. 3 is a flow chart illustrating a vehicle warning method according to another exemplary embodiment. As shown in fig. 3, the step S12 of outputting the first prompt message indicating the approach of multiple targets when it is detected that at least two moving objects approach the vehicle on the basis of fig. 1 includes the following steps.
In step S121, the velocity of each moving object is acquired.
In step S122, a moving object having a speed greater than a preset threshold is determined as a target object.
In step S123, when the number of the objects is 2 or more, a first prompt message indicating that there is a plurality of objects approaching is output.
The moving object with the speed greater than the preset threshold value can be considered to have certain threat to the safety of the vehicle. For example, when the vehicle opens, the rear vehicle (moving object) traveling at a high speed may cause a collision injury to the door of the vehicle and even a person who gets off the vehicle, and when the vehicle turns, the rear vehicle traveling at a high speed may cause a collision to the vehicle. The preset threshold may be a speed that is determined experimentally or empirically in advance.
If the speed of the moving object is not greater than the preset threshold, it may be determined that the moving object does not threaten the safety of the vehicle, and may not be determined as the target object.
In this embodiment, the moving object is divided into a target object having a security threat to the vehicle and other objects having no threat by the speed of the moving object, and a first prompt message indicating that multiple targets are close to the moving object having the security threat is output, so that the prompt message has a more obvious prompt function.
In yet another embodiment, the method may further comprise: the moving objects are monitored in the rear left and right of the vehicle, or in the rear side of the execution side, which is the side where the door is opened or turned, when one side of the vehicle is determined as the execution side.
Specifically, in the foregoing embodiment, the detection may be performed using a speed detection device provided behind the vehicle, resulting in the speed of the moving object behind the vehicle. When the moving object reaches the vehicle lateral rear (left rear or right rear), detection may be performed using a speed detection device provided on the vehicle lateral side.
The execution side is the side that opens the door or turns to. For example, when the driver or passenger presses an unlock key of the left door, indicating that the left door is unlocked, the left side is the actuating side, or when the driver turns a left turn signal, the left side is the actuating side; alternatively, when the driver turns the steering wheel to the left, the left side is the actuation side. When the left side of the vehicle is determined as the execution side, only the moving object behind the left side may be monitored, and when the right side of the vehicle is determined as the execution side, only the moving object behind the right side may be monitored, or the moving objects behind both the left and right sides may be monitored simultaneously.
And when the number of the target objects behind the vehicle, behind the left side and behind the right side is greater than or equal to 2, outputting a first prompt message.
In this embodiment, it is possible to detect a moving object laterally behind the vehicle, or to monitor only a moving object laterally behind the execution side, so that the protection of the vehicle is more accurate.
In yet another embodiment, the method may further comprise: and when only one moving object is detected to approach the vehicle, outputting a second prompt message for indicating that a single object approaches.
When only one moving object is detected to approach the vehicle, the output second prompt message is different from the first prompt message. The second prompting message can also be a light, a light flashing, a voice, a buzzer, etc. For example, when one vehicle is monitored on the left rear side of the vehicle and the moving speed is greater than the speed threshold value, one indicator lamp on the door handle on the left side of the vehicle is controlled to be turned on, and when two vehicles are monitored on the left rear side of the vehicle and the moving speeds are greater than the speed threshold value, two indicator lamps on the door handle on the left side of the vehicle are controlled to be turned on. When the passenger sees that both lamps are on, more than one vehicle behind the passenger sees that the door is opened after seeing the clear situation.
Outputting the second prompting message may include one or more of: controlling a plurality of indicator lights on the external rearview mirrors on the sides of the plurality of moving objects to be turned on or flash; controlling a plurality of indicator lights on a door handle on the side where a plurality of moving objects are located to be turned on or to flash; and outputting the audio message. The first cue message and the second cue message may be audio messages of different frequencies. For example, the first alert message may be more frequent than the second alert message, indicating a greater urgency and danger of the situation.
In the embodiment, the prompt message of single target approach and the prompt message of multi-target approach are distinguished, so that a user can easily distinguish the danger caused by a rear moving object, and a safety measure can be taken in time.
In yet another embodiment, the method further comprises:
determining the current running state of the vehicle;
when the number of the objects is 2 or more, the current running state of the vehicle is running, and the objects are on the execution side of steering, the steering damping of the steering wheel is increased to a predetermined damping.
The running state of the vehicle may include running and stopping. For example, when the current vehicle speed is greater than a predetermined vehicle speed threshold (e.g., 3km/h), the current running state may be determined to be in-running; when the current vehicle speed is less than or equal to the predetermined vehicle speed threshold, the current driving state may be determined to be in parking.
The execution side of the steering indicates the side of the vehicle that will be turned. For example, if the driver turns a left turn signal, the left side is the execution side of the turn, the driver turns a right turn signal, and the right side is the execution side of the turn. Alternatively, if the driver turns the steering wheel to the left, the left side is the execution side of the steering, and if the driver turns the steering wheel to the right, the right side is the execution side of the steering.
In order to avoid a vehicle collision accident caused by the driver just hitting the steering wheel when the rear vehicle overtakes while the vehicle is running, in this embodiment, the steering damping of the steering wheel is increased in such a case. The steering damping of the steering wheel is used to oppose the steering torque applied by the driver. The steering wheel does not rotate when the steering torque applied by the driver is less than the steering damping of the steering wheel, and does so when the steering torque applied by the driver is greater than the steering damping of the steering wheel. Thus, increasing the steering damping of the steering wheel can provide the driver with a greater resistance, but the steering wheel is not fully immobilized because the steering damping of the steering wheel is increased only to a predetermined damping and is not fully locked. When the driver still intends to steer after feeling the increased damping, a larger force can be used to accomplish the steering. The predetermined damping can be experimentally derived beforehand.
In this embodiment, in the above case, the control is performed to increase the steering damping of the steering wheel, and the control functions not only as a prompt but also as a hindrance to dangerous driving to some extent.
In yet another embodiment, the method further comprises:
determining the current running state of the vehicle;
and when the number of the target objects is more than or equal to 2, the current running state of the vehicle is in parking, and the target objects are positioned at the door opening execution side, the unlocking instruction of opening the door is suspended until the preset time length is reached or a forced unlocking instruction is received.
In order to avoid a vehicle collision accident caused by the fact that a driver or a passenger just opens a door of a vehicle when a rear vehicle passes through while the vehicle is parked, in this embodiment, an unlocking command is executed with a delay of a predetermined time period in such a case, or a passenger is required to execute a forced unlocking command. The predetermined period of time may be obtained in advance by experiment, and the predetermined period of time may be set as a period of time during which a vehicle within a predetermined range behind the vehicle can exit the vehicle. When the vehicle in the preset range behind the side of the vehicle is driven out of the vehicle, the vehicle is not in danger of collision when the vehicle is driven in the door, and the vehicle door can be unlocked.
The unlocking instruction is executed in a delayed manner, so that a driver or passengers can feel that the door is opened with larger resistance, but the door can be unlocked only by delaying, and the door can be unlocked without delaying by sending a forced unlocking instruction. The forced unlock instruction may trigger generation in a more drastic manner than the unlock instruction.
In this embodiment, in the above case, the unlocking instruction is executed with a delay or the door needs to be unlocked by forcing the unlocking instruction, which not only plays a role of prompting, but also plays a role of hindering dangerous driving to a certain extent.
In still another embodiment, the unlocking instruction is generated when the electronic switch of the vehicle door is pressed for a time period longer than a preset first time period, and the forced unlocking instruction is generated when the electronic switch is pressed for a time period longer than a preset second time period, wherein the first time period is shorter than the second time period.
That is, the forced unlock instruction may be triggered to be generated by pressing the electronic switch of the vehicle door for a greater length of time than the unlock instruction. That is, the unlocking condition of the electronic door is adjusted to further verify the will of opening the door of the passenger. The second duration is less than the predetermined duration. In the embodiment, the passenger needs to unlock the vehicle door for a longer time than that for pressing the electronic switch of the vehicle door at ordinary times, the intention of the passenger to open the door is further confirmed, and the safety of opening the door is improved.
In yet another embodiment, the unlock command is generated when a mechanical switch of the vehicle door is applied with a torque greater than a predetermined first torque threshold, and the forced unlock command is generated when the mechanical switch is applied with a torque greater than a predetermined second torque threshold, the first torque threshold being less than the second torque threshold.
That is, the forced unlock command may be triggered to be generated by applying a greater torque to a mechanical switch of the vehicle door than the unlock command. That is, the unlocking condition of the mechanical door is adjusted to further verify the will of opening the door of the passenger. The first and second torque thresholds may be experimentally derived. In the embodiment, the passenger needs to unlock the vehicle door by using larger torque than that applied to the mechanical switch at ordinary times, the intention of the passenger to open the door is further confirmed, and the safety of opening the door is improved.
FIG. 4 is a flow chart illustrating a vehicle warning method according to yet another exemplary embodiment. Referring to fig. 4, after the vehicle is started, the vehicle early warning system can perform self-checking, and if the vehicle early warning system is abnormal, a fault alarm is performed; if the system is normal, the system is in standby. During standby, the moving speed of the moving object on the left rear side and the right rear side is monitored by a vehicle-mounted millimeter wave radar, the vehicle speed is monitored by a vehicle speed sensor, and whether an unlocking instruction of a vehicle door exists or not is monitored by a vehicle lock sensor.
If the moving speeds of at least two moving objects behind the vehicle are larger than the preset speed threshold value, the system is activated, primary early warning of multi-target indication is executed, a first prompt message is output, a door handle flashing lamp in the cabin warns, and a rearview mirror frame flashing lamp outside the cabin warns.
If the driver is monitored to change the steering lane (the steering wheel is applied with torque), secondary early warning of multi-target indication is executed, and the steering damping of the steering wheel is increased. If the received torque applied by the steering wheel is larger than the increased preset damping (the driver forcibly turns), the steering lane change is executed, and meanwhile, the cabin warning and the cabin outside warning are still executed.
If the situation that a driver or a passenger wants to unlock the door lock (an unlocking instruction is triggered) is monitored, secondary early warning of multi-target indication is executed, and the unlocking instruction is suspended until a preset time length is reached or a forced unlocking instruction is received. Before the preset time is reached, if a forced unlocking instruction (forced unlocking) is generated, unlocking the vehicle door is executed, and meanwhile, the in-cabin warning and the out-cabin warning are still executed.
