Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.
Referring to fig. 1-2, a vehicle-mounted intelligent driving early warning system 100 according to an embodiment of the present application is described below, where the vehicle-mounted intelligent driving early warning system 100 can flexibly select early warning operation in combination with an actual early warning requirement of a vehicle and a consciousness condition of a driver 103 to a risk area when performing early warning prompt, so as to perform early warning operation more appropriately to a requirement of the driver 103, and improve use experience of the driver 103.
As shown in fig. 1 and fig. 2, the vehicle-mounted intelligent driving early warning system 100 according to the embodiment of the present application includes: the system comprises an environment early warning module 10, a sight line detection module 20, a main control module 30 and an early warning execution module 40.
The environmental early warning module 10 is used for preliminarily acquiring the early warning requirement of the vehicle. Wherein, preliminary early warning demand of obtaining the vehicle includes: the method comprises the steps of identifying environmental information in a target area, and acquiring vehicle body state information when the target area is identified to be in a non-safety condition so as to identify the early warning requirement of a vehicle according to the vehicle body state information. The environmental early warning module 10 may be a vehicle scale processing chip such as S32V234K, and the environmental early warning module 10 may be located inside a control screen in a central operation area as part of an ADAS domain controller.
The environment early warning module 10 can be used for analyzing and judging things and road conditions in the environment where the vehicle is located so as to identify whether the surrounding environment of the vehicle has a safety risk relative to the vehicle, and the environment early warning module 10 can also be used for analyzing and judging the state of the vehicle body so as to preliminarily determine whether the vehicle needs early warning operation by combining the surrounding environment and the running state of the vehicle body. The environment early warning module 10 is used for being connected with the vehicle body controller 102 and acquiring environment sensing information according to the sensor hardware 101, that is, the device for acquiring the environment information may be the sensor hardware 101 electrically connected to the outside, and specifically may include a laser radar, a millimeter wave radar, an ultrasonic radar, a front view camera, and the like.
That is, after the environment in which the vehicle is located is analyzed and determined, the running state of the vehicle body needs to be analyzed. As in some embodiments, there is a vehicle running at a reduced speed in front of the vehicle and the distance from the vehicle is small, and there is a high possibility that the vehicle may collide with the front vehicle, i.e. there is a risk of collision. At this time, the operation state of the vehicle needs to be acquired and analyzed to ensure whether the operation state of the vehicle can avoid corresponding risks. The environmental early warning module 10 is used for being connected to the vehicle body controller 102, for example, the environmental early warning module 10 may be connected to the vehicle body controller 102 through a CAN network to obtain the operating state of the vehicle body according to the vehicle body controller 102.
If the vehicle is in slow running and the deceleration range is larger than that of the front vehicle, the risk of rear-end collision does not occur even if the distance between the vehicle and the front vehicle is small, namely the early warning requirement does not exist; or if the vehicle is not operated for deceleration or braking, and the risk of the vehicle before rear-end collision easily exists in the current running state, the risk of the vehicle before rear-end collision easily exists, namely the early warning requirement exists. Thus, the environment early warning module 10 may make a preliminary judgment on the driving danger based on the environment perception information and the vehicle body state information, and preliminarily decide whether to issue the early warning information to the driver 103.
The sight line detection module 20 is configured to acquire a sight line state of the driver 103, that is, the sight line detection module 20 is configured to determine a position where the sight line of the driver 103 is located, where when the sight line detection module 20 detects that the sight line of the driver 103 has fallen into an area or a position where a safety risk exists, it is known that the driver 103 has watched the corresponding area and has a safety risk, and if the sight line detection module 20 detects that the sight line of the driver 103 has not fallen into an area or a position where a safety risk exists, it is known that the driver 103 has not watched the corresponding area and has a safety risk at this time, and different emergency measures are taken by the vehicle-mounted intelligent driving early warning system 100 for different sight line states.
As shown in fig. 1, the environment early warning module 10, the line of sight detection module 20, and the line of sight detection module 20 are all electrically connected to the main control module 30, and the early warning execution module 40 is configured to execute an early warning operation, that is, the environment early warning module 10, the line of sight detection module 20, and the line of sight detection module 20 can all perform signal transmission with the main control module 30. Therefore, the early warning requirement of the environment early warning module 10 for initially acquiring the vehicle can be sent to the main control module 30, the sight line state of the driver 103 detected by the sight line detection module 20 can also be transmitted to the main control module 30 in a signal manner, the main control module 30 can also output a control signal to the early warning execution module 40 so as to control the early warning execution module 40, and the early warning execution module 40 can output an early warning signal so that the driver 103 finds that a safety risk exists.
Wherein the main control module 30 is configured to control the early warning execution module 40 according to the early warning requirement of the vehicle and the sight line state of the driver 103 obtained preliminarily. Thus, the control operation of the early warning execution module 40 by the main control module 30 may refer to the sight line state of the driver 103 based on not only the safety risk existing in the vehicle environment but also the running state of the vehicle to further determine whether the early warning prompt needs to be executed. The main control module 30 is a vehicle scale level microprocessor such as MPC5746R, and the integrated early warning controller may be located inside the control screen in the central operating area as part of the ADAS domain controller.
If the collision risk on the side of the vehicle is determined by the environment early warning module 10 and the early warning requirement is preliminarily obtained, the main control module 30 analyzes and judges the sight state of the driver 103, if the sight of the driver 103 is not at the collision risk position on the side of the vehicle, the main control module 30 controls the early warning execution module 40 to execute early warning operation to remind the driver 103 to watch the safety risk area, if the sight of the driver 103 enters the collision risk position on the side of the vehicle, the main control module 30 does not output a control instruction to the early warning execution module 40 to avoid the excessive operation of the early warning execution module 40, thereby avoiding the early warning prompt after the driver 103 watches the safety risk problem of the vehicle, preventing the later made early warning prompt from causing the discomfort and the fidget of the driver 103 and improving the user experience, and greatly improve the intelligent degree of the vehicle and the intelligence of the whole vehicle.
According to the vehicle-mounted intelligent driving early warning system 100 of the embodiment of the application, the main control module 30 is set to control the early warning execution module 40 according to the early warning requirement of the vehicle and the sight state of the driver 103, therefore, the early warning prompt can be avoided being carried out after the driver 103 watches the vehicle and has safety risks, the early warning prompt made after the driver 103 is prevented from causing the driver 103 to be uncomfortable and irritated, the user experience is improved, the intelligent degree of the vehicle is greatly improved, and the intelligence of the whole vehicle is improved.
In some embodiments, the main control module 30 is configured to identify the sight line state of the driver 103 when the environmental early warning module 10 acquires that there is an early warning requirement in the target area.
It should be noted that the target area refers to an area where the vehicle is at a safety risk, for example, when the vehicle collides with a preceding vehicle, the target area refers to a front area of the vehicle, that is, an area directly facing the preceding vehicle; or when the side or the rear of the vehicle has a driving collision risk, the target area refers to the side or the rear area of the vehicle, or when the vehicle has a lane departure risk, the target area refers to an area with obvious lane departure. Thus, in different safety risk situations, the respective risk zone is determined as the target zone, thereby further determining whether the line of sight of the driver 103 falls within the zone.
Wherein, main control module 30 controls early warning execution module 40 to execute the early warning operation when driver 103's sight state does not fall into the target area, and main control module 30 does not control early warning execution module 40 to execute the early warning operation when driver 103's sight state falls into the target area, from this, can confirm whether driver 103 gazes at the target area that has the safety risk to ensure that main control module 30 carries out more accurate instruction output, promote user's use experience.
Further, in some embodiments, the main control module 30 is configured not to control the warning performing module 40 to perform the warning operation when the duration that the sight line state of the driver 103 falls within the target area is greater than a set time.
That is to say, when the sight line state of the driver 103 falls into the target area and is not necessarily focused on the risk area, it can be understood that the driver 103 may perform a short glance at the surrounding environment in order to ensure the safety of the surrounding driving environment during the driving of the vehicle, and therefore, in the present application, by not controlling the early warning execution module 40 to perform the early warning operation when the duration that the sight line state of the driver 103 falls into the target area is longer than the set time, the driver 103 may be continuously focused on when recognizing that the safety risk exists, and the accuracy and reliability of the vehicle-mounted intelligent driving early warning system 100 are improved.
The setting time can be flexibly set according to actual conditions, for example, the setting time can be 3s or 5s or set to 8s, so as to be more beneficial to determining that the driver 103 really gazes at the risk area, and certainly, the setting time cannot be set to be too long, so as to avoid that the driver 103 cannot reasonably operate in time due to too severe requirements for the determination of the sight line state.
In some embodiments, the warning demand includes at least one of a lane departure warning, a door opening obstacle warning, and a vehicle collision warning. That is, the environmental early warning module 10 can preliminarily determine that the safety risk can include lane departure early warning, or include the early warning of the barrier that opens the door, or include the early warning of the collision of the vehicle, or be any two of the lane departure early warning, the early warning of the barrier that opens the door and the early warning of the collision of the vehicle, or even include these three kinds of early warning demands to satisfy the early warning demands of the vehicle under different safety risk conditions, and improve the practicability of the vehicle-mounted intelligent driving early warning system 100. Of course, the early warning requirement may also include other situations with safety risks, such as the problem that an obstacle exists in front of the vehicle and the obstacle cannot be safely crossed, or the risk that the inner tube of the vehicle is exposed and the tire is burst.
In some embodiments, acquiring the gaze state of the driver 103 includes acquiring a direction and an area in which the gaze of the driver 103 is located. That is to say, after the orientation of the driver 103 is obtained, the direction of the sight line of the driver 103 is determined, and the specific gazing area of the driver 103 is further obtained, so that whether the driver 103 effectively gazes the area with the safety risk is more accurately determined, and accurate instruction output by the main control module 30 is facilitated.
In some embodiments, gaze detection module 20 includes an eye tracker or a camera mounted in the vehicle.
The eye tracker can adopt a commercial eye tracker with a single function, so that the eye tracker can detect the movement direction of the eyes of the driver 103 in real time, and thus acquire the direction and the area of the eyes of the driver 103. And commercial eye moves appearance is wearable equipment, can attach on driving seat, and the installation of being convenient for just can carry out more accurate detection to driver 103's sight.
The camera can be installed on the inner side of the left A column of the vehicle or on the inner side of the right A column, so that the camera can detect the sight line of the driver 103 at any time, wherein the camera can be a multifunctional camera, and can replace complex hardware equipment through algorithms written additionally such as face tracking, eye detection, injection point positioning and the like, so that the sight line state of the driver 103 can be acquired more favorably. And the camera in this application can also be used as other functions, for example, detect the fatigue state of driver 103 to carry out corresponding safety warning to driver 103.
In some embodiments, the vehicle-mounted intelligent driving warning system 100 further includes: the driver 103 is used for acquiring the brain wave state of the driver, and the main control module 30 is configured to control the early warning execution module 40 according to the early warning requirement of the vehicle, the sight line state of the driver 103 and the brain wave state which are acquired preliminarily.
That is, after the early warning demand of the vehicle is preliminarily acquired by the environment early warning module 10 and the sight line state of the driver 103 is acquired by the sight line detection module 20, the brain wave state of the driver 103 may be further received, and it is understood that the current consciousness state of the driver 103, i.e., whether to make a thinking of safety consciousness in an area where there is a safety risk, may be analyzed by the brain wave state.
From this, can combine the early warning demand that preliminary acquirees, driver 103's sight state and brainwave state are controlled the execution early warning device, can do benefit to more and satisfy user's user demand, avoid watching the early warning suggestion again after the vehicle has the problem of safety risk at driver 103, the early warning suggestion of making after preventing causes driver 103's aversion, fidget, promote user experience, and greatly improved the intelligent degree of vehicle, promote whole car intelligence.
In some embodiments, performing the alert operation includes at least one of a light alert, a sound alert, a display alert, and a vibration alert. That is to say, the main control module 30 can control the execution of the warning operation to perform the warning prompt in any one of the light warning, the sound warning, the display warning and the vibration warning, or in a form of selectively combining the light warning, the sound warning, the display warning and the vibration warning, so as to be more beneficial to the reminding of the driver 103.
The execution early warning module can be a built-in structure device of the vehicle body. If the execution early warning module comprises a loudspeaker positioned in an instrument panel, the execution early warning module can also be a loudspeaker in an in-vehicle broadcasting system, and is used for playing a sound prompt to realize sound early warning; or the execution early warning module comprises light combination flashing, and the light of the execution early warning module can be a peripheral vehicle body light or a light in an automobile cabin, so that light indication is carried out to realize light early warning; or the execution early warning module comprises a driving seat used by the driver 103, and vibration early warning is realized through seat vibration; even the execution early warning module can comprise a display screen, and the display screen can be a display screen of an instrument panel, a display screen of a central operation area or other virtual display screens so as to realize sound early warning.
In some specific implementations of the present application, the decision of the main control module 30 is based on:
1) when the initial decision result of the environment early warning module 10 is "not to issue early warning information", the sight line result of the sight line detection module 20 is not considered any more, and the main control module 30 directly makes a final decision result of "not to issue early warning information";
2) when the preliminary decision result of the environment early warning module 10 is "issue early warning information", the main control module 30 considers the sight line result of the sight line detection module 20 to make a judgment, if the sight line of the driver 103 stays in the abnormal driving state area causing the environment early warning module 10 to make the preliminary early warning decision result within the time period T from this time, the final decision result is "not issue early warning information", otherwise, the final decision result is "issue early warning information".
From this, through on-vehicle intelligent driving early warning system 100 in this application, can do benefit to more and satisfy user's user demand, avoid gazing at driver 103 and carry out early warning suggestion again after the vehicle has the problem of safety risk, the early warning suggestion of making after preventing causes driver 103's aversion, fidgetiness, promotes user experience, and has greatly improved the intelligent degree of vehicle, promotes whole car intelligence.
