Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Example 1

In order to solve the problem of how to safely remind a driver under the condition of ensuring driving safety in the prior art, the embodiment of the invention provides a vibration reminding method.

The main execution body of the method may be an Advanced Driving Assistance System (ADAS), an Electronic Control Unit (ECU), a vehicle-specific microcomputer controller, a vehicle-mounted system, a vehicle-mounted computer, or the like, or may be an application program or application installed in the Advanced Driving assistance system, the ECU, the vehicle-specific microcomputer controller, the vehicle-mounted system, or the vehicle-mounted computer.

For convenience of description, the embodiment of the present invention introduces the method by taking the execution subject of the method as an example of a microcomputer controller dedicated for an automobile. It can be understood by those skilled in the art that the embodiment of the present invention is described by taking the car-specific microcomputer controller as an example, and is only an exemplary illustration, and does not limit the protection scope of the claims corresponding to the present invention.

Specifically, an implementation flow of the method provided by the embodiment of the present invention is shown in fig. 1a, and includes the following steps:

and step 11, monitoring whether a vibration reminding triggering event occurs.

The vibration reminding triggering event can guide events causing potential safety hazards in the driving process, such as fatigue driving, drunk driving, overspeed driving, lane-conflict and rushing to go, intersection non-observation, illegal overtaking, passing not according to signal lamp reminding, driving to see a mobile phone, lane departure or too close distance with a front vehicle or a rear vehicle.

In the embodiment of the invention, information for representing whether the vibration reminding trigger event occurs in the driving process, such as a face image of a driver, can be collected through monitoring equipment such as a vehicle-mounted camera, and the collected information for representing whether the vibration reminding trigger event occurs is sent to the special microcomputer controller for the automobile, so that the special microcomputer controller for the automobile can judge whether the vibration reminding trigger event occurs based on the information. For example, in the driving process of an automobile, the vehicle-mounted camera can actively acquire a face image of a driver in the driving process, and then the acquired face image is sent to the special microcomputer controller for the automobile, so that the special microcomputer controller for the automobile can judge whether the driver is in fatigue driving or drunk driving.

Wherein, on-vehicle camera can be based on wifi module bluetooth module, establish communication connection with this vibrating device that possesses wifi module bluetooth module.

Or, in the embodiment of the present invention, information indicating whether a vibration-reminding trigger event occurs in a driving process, such as driving information and road condition information of a vehicle, may also be collected in real time by the intelligent driving computer, and the collected driving information and road condition information are sent to the vehicle-specific microcomputer controller, so that the vehicle-specific microcomputer controller may determine whether an event such as a vehicle collision event, a lane departure, or the like may occur in the vehicle.

In the embodiment of the invention, whether the automobile or the driver is in a dangerous state can be effectively pre-judged by monitoring whether the vibration reminding triggering event occurs, so that the driver can be reminded before a safety accident occurs, and the safety of automobile driving is improved.

As shown in fig. 1b, the monitoring process in step 11 is further explained below by taking the vibration reminding triggering event as a fatigue driving early warning event as an example.

Step 101, collecting information representing the fatigue degree of a driver.

Generally, when a driver is in fatigue driving, the blinking frequency and/or the frequency of the yawning in a preset time period may be different from the blinking frequency and/or the frequency of the yawning in a non-fatigue state.

In practical application, information representing the fatigue degree of a driver can be acquired through image acquisition equipment such as a vehicle-mounted camera and a video recorder, for example, when an automobile is started, the camera can be started to capture a facial image of the driver in real time, the captured facial image is sent to a special automobile microcomputer controller, and the special automobile microcomputer controller can calculate the blinking frequency and/or the yawning frequency of the driver according to the facial image.

The blinking frequency may be determined according to the number of frames occupied by the blinking image in the face image of the driver acquired within a preset time period, for example, assuming that the number of frames occupied by the blinking image in the human eye image acquired within 3 minutes is 27 frames, the blinking frequency may be determined to be 9(27/3) times/minute.

Similarly, the yawning frequency can be determined according to the number of frames occupied by the yawning image in the facial image of the driver collected in the preset time period.

And 102, monitoring whether a fatigue driving early warning event occurs or not based on preset fatigue driving critical conditions and collected information representing the fatigue degree of the driver.

The preset fatigue driving critical condition may be understood as a judgment condition for judging whether the driver is in a fatigue driving state. The preset fatigue driving critical condition can be stored in the memory space of the special microcomputer controller for the automobile in advance.

In an embodiment of the present invention, the preset critical condition for fatigue driving may include: a preset blink frequency threshold and/or a preset yawning frequency threshold. Alternatively, the preset blink frequency threshold and the preset yawning frequency threshold may be determined according to empirical values of driving fatigue simulation analysis, for example, the preset blink frequency threshold may be set to 10 times/min and the preset yawning frequency threshold may be set to 0.2 times/min according to empirical values.

Optionally, if the information representing the fatigue degree of the driver collected in step 101 includes a blinking frequency; then, monitoring whether a fatigue driving early warning event occurs based on the preset fatigue driving critical condition and the collected information representing the fatigue degree of the driver, which may include: and monitoring whether the fatigue driving early warning event occurs or not based on a preset blinking frequency threshold value and the collected blinking frequency.

For example, since the eyes may be in a closed state when the driver is in a fatigue state, that is, the number of blinks in the preset time period may be reduced relative to the number of blinks in a non-fatigue state in the preset time period, in an embodiment of the present invention, when the collected blink frequency is less than a preset blink frequency threshold, it may be determined that the fatigue driving warning event occurs.

Alternatively, in one embodiment, if the information characterizing the fatigue level of the driver collected in step 101 includes a yawning frequency; then, monitoring whether a fatigue driving early warning event occurs based on the preset fatigue driving critical condition and the collected information representing the fatigue degree of the driver, which may include: and monitoring whether a fatigue driving early warning event occurs or not based on a preset yawning frequency threshold value and the collected yawning frequency. For example, when the acquired yawning frequency is greater than a preset yawning frequency threshold, it may be determined that a fatigue driving warning event occurs.

Optionally, to avoid the misjudgment, in an embodiment, whether a fatigue driving warning event occurs may be monitored based on the blinking frequency and the yawning frequency in combination with the closed state information of the eyes in the preset time period.

For example, the proportion of the eye closure state in a certain time may be calculated in advance, and hereinafter, denoted by E, for example, E ═ N/N; wherein N is the total frame number of the human eye video collected in a certain time period; n is the number of frames the eye occupies in the closed state for a certain period of time.

Then, judging whether E is larger than a preset experience value of driving fatigue simulation analysis, and if so, determining that a fatigue driving early warning event occurs; if not, further judging whether the collected blink frequency is smaller than a preset blink frequency threshold value or whether the collected yawning frequency is larger than a preset yawning frequency threshold value. Therefore, the phenomenon that the normal blinking or yawning behaviors of the driver in the driving process are judged to be in the fatigue state by mistake can be avoided, and the accuracy of the step 102 is further improved.

In one embodiment, after the above steps are performed, if it is detected that a vibration alert triggering event occurs, the following step 12 is performed.

And step 12, determining a vibration mode matched with the type of the vibration reminding trigger event according to the preset mapping relation between the event type and the vibration mode and the type of the vibration reminding trigger event.

In the embodiment of the invention, after the vehicle-specific microcomputer controller determines that the vibration trigger event occurs, the vibration mode matched with the type of the vibration reminding trigger event can be further determined according to the preset mapping relation between the event type and the vibration mode and the type of the vibration reminding trigger event. The preset mapping relation can be stored in a memory space of the special microcomputer controller for the automobile in advance.

Specifically, the vibration mode may include a vibration frequency and a vibration mode. Wherein, the vibration frequency includes low frequency, middle frequency, high frequency, etc.; the vibration mode includes bilateral vibration, unilateral vibration and the like.

The preset mapping relationship can be understood as a corresponding relationship between the type of the vibration reminding trigger event and the vibration mode, and under the condition that the type of the vibration reminding trigger event is known, the vibration mode matched with the type of the vibration reminding trigger event can be determined according to the preset mapping relationship.

Optionally, in consideration that the vibration trigger event may include multiple types, if a single vibration mode is used to remind the driver, the driver may not clearly know the type of the vibration trigger event, so that the vibration trigger event cannot be responded to in time, in this embodiment of the present invention, multiple vibration modes may be used to remind the driver, where each vibration mode may correspond to one type of vibration prompt trigger event, so that the driver may clearly know the type of the vibration trigger event according to the vibration mode, and thus may respond to the vibration trigger event in time. For example, in one embodiment, the vibration modes may include: at least one of high-frequency single-side vibration, medium-frequency single-side vibration, low-frequency single-side vibration, high-frequency double-side vibration, medium-frequency double-side vibration and low-frequency double-side vibration.

Based on the above description, assuming that the type of the vibration reminding trigger event includes an automobile collision early warning event, a lane departure early warning event, and a fatigue driving early warning event, the preset mapping relationship between the type of the vibration reminding trigger event and the vibration mode may be as shown in table 1 below:

TABLE 1

Vibration alert trigger event type	Vibration mode
		Automobile collision early warning event	High frequency bilateral vibration
Lane departure warning event	Medium frequency bilateral vibration
		Fatigue driving warning event	Low frequency bilateral vibration

In addition, considering that the degrees of the same type of vibration triggering event may be different, in the embodiment of the present invention, in order to accurately remind the driver, the vibration mode matching both the type and the degree of the vibration reminding triggering event may be determined according to the degree of the vibration triggering event.

For example, the following describes an embodiment of the present invention by taking the type of the vibration trigger event as the type of the fatigue driving warning event.

Optionally, the preset mapping relationship may include a corresponding relationship between the type of the fatigue driving warning event, at least two fatigue degrees, and at least two corresponding vibration modes.

In one embodiment, assuming that the fatigue degrees include three types of severe fatigue, moderate fatigue and mild fatigue, the corresponding preset mapping relationship may be as shown in table 2 below:

TABLE 2

As shown in table 2, if a fatigue driving warning event is monitored, and the fatigue driving degree is severe fatigue, it can be determined that the vibration mode is low-frequency bilateral long-time continuous vibration.

The above vibration mode is merely an exemplary illustration, and does not limit the embodiments of the present invention.

It is considered that when the same driver is subjected to different levels of fatigue, different levels of stimulation are often required in order to stimulate him to respond the same. For example, when the driver is in slight fatigue, the driver can be stimulated to refresh by slight vibration, so that the driver can recover the waking state; in severe fatigue, a slight violent vibration is required to stimulate the driver to recover the waking state. Therefore, in the embodiment of the invention, the vibration mode matched with both the type and the degree of the vibration reminding triggering event can be determined based on the fatigue degree.

Step 13, controlling the vibration device to work in the matched vibration mode according to the matched vibration mode; the arrangement position of the vibration device in the automobile comprises: the main driving position of the automobile.

In the embodiment of the invention, after the vehicle-specific microcomputer controller determines the vibration mode matched with the type of the vibration reminding trigger event according to the step 12, the vibration device can be controlled to work in the matched vibration mode, namely the vibration device is controlled to adopt the same vibration frequency and vibration mode as the determined vibration mode to carry out vibration reminding on the driver.

Specifically, the MCU microprocessor in the vehicle-specific microcomputer controller may convert the vibration frequency and the vibration mode corresponding to the vibration mode into digital signals, and perform detection, amplification, regeneration, and other processing on the digital signals. After the MCU microprocessor finishes processing, the digital signal is input into a control logic circuit in a special microcomputer controller for the automobile to generate a pulse signal, and the pulse signal is driven by the control logic circuit to control a power tube to output to a vibration device, so that when the vibration device receives the pulse signal, the vibration device can respond to the pulse signal and work under the vibration frequency and the vibration mode which are the same as the vibration mode.

For example, assuming that the vibration trigger event includes a car crash trigger event, the car-specific microcomputer controller may activate the vibration device within 10 milliseconds after determining the vibration mode, so that the vibration device performs high-frequency bilateral vibration. Optionally, the high frequency may be, for example, 55 to 67 Hz, and the vibration vertical acceleration may be 55 to 72m/s²。

Alternatively, assuming that the vibration triggering event includes a lane departure event, the vehicle-specific microcomputer controller may control the vibration device to be activated before deviating from the original lane for 0.5 seconds (referred to as activation time), thereby starting the vibration alert.

The activation time of the vibration device by the vehicle-specific microcomputer controller is only an exemplary illustration, and in practical application, the response time required by a plurality of drivers for vibration reminding and responding to the vibration reminding can be counted, and a reasonable activation time is set based on the counting result. As shown in fig. 1c, the vibration device may include vibration motors (011 and 012), a wire harness (016), snaps (013 and 014), a wire harness terminal (015), and the like. Wherein, the buckle is used for fixed pencil, and the pencil terminal is used for transmitting the signal and electrically conducts.

As shown in fig. 1d and 1e, in consideration of comfort during driving, in the embodiment of the present invention, the vibration device may be mounted on the left side wing and/or the right side wing of the seat cushion in the main driving position of the vehicle, so as to avoid mounting the vibration device on the lower layer of the seat cushion in the main driving position of the vehicle or at the middle position of the backrest in the main driving position of the vehicle.

In fig. 1d, 022 and 023 denote vibration motors mounted to the right side wing and the left side wing of the seat cushion in the main driving position of the vehicle, respectively. 021 denotes a cushion foam of the seat in the main driving seat.

Example 2

How the method provided by the embodiment of the invention is applied in practice is described below in combination with an actual scene.

As shown in fig. 2a, for a schematic diagram of a vibration reminding system for implementing a vibration reminding method according to an embodiment of the present invention, before describing a vibration reminding method, a system for implementing the vibration reminding method will be described in some detail. The system mainly comprises a collecting device, a decision device and an executing device.

the decision device is used for determining a vibration mode matched with the type of the currently generated vibration trigger event according to the information acquired by the acquisition device if the vibration trigger event occurs;

and the executing device is used for executing the vibration operation corresponding to the vibration mode determined by the decision device.

Optionally, in order to reduce the structural complexity of the vibration reminding system and reduce the economic cost, in the embodiment of the present invention, an ADAS of an automobile may be used as an acquisition device to acquire information for characterizing whether a vibration trigger event occurs, so that, since the ADAS itself includes a high-speed camera and a millimeter wave radar, it is not necessary to additionally add a new information acquisition unit for implementing the method provided by the present solution. In addition, an Electronic Control Unit (ECU) may be employed as the decision means. The ECU and the ADAS may communicate with each other through a Controller Area Network (CAN).

As shown in fig. 2b, the following describes the vibration method provided by the present invention based on the above vibration reminding system:

and step 21, the ADAS system collects information used for representing whether a vibration trigger event occurs or not based on the high-speed camera and the millimeter wave radar and sends the collected information to the ECU.

The information for representing whether the vibration triggering event occurs may include driving information of the vehicle, road condition information, or facial information of the driver during driving.

The driving information and road condition information of the automobile can be collected by the millimeter wave radar. The driving information includes, for example: the current running speed of the automobile, the current distance between the automobile and the front and rear vehicles and the like are used for representing whether a vibration reminding event occurs or not; the traffic information includes, for example: at least one of route information, road segment information, or traffic information, for characterizing whether a vibration alert triggering event occurs.

The facial information of the driver during driving can be collected by the high-speed camera.

Step 22, after receiving the information sent by the ADAS system, the ECU may determine whether a vibration trigger event occurs based on the information; and under the condition that the vibration triggering event is determined to occur, determining the vibration mode matched with the type of the vibration reminding triggering event according to the preset mapping relation between the event type and the vibration mode and the type of the vibration reminding triggering event. The preset mapping relation can be stored in a storage space of the ECU in advance.

Specifically, in the present embodiment, assuming that the information received by the ECU includes a facial image of the driver for representing whether the vibration trigger event occurs, whether the vibration trigger event occurs may be determined according to the following sub-steps shown in fig. 2 c.

A substep 221 of tracking eyes and mouths based on the collected face images;

a substep 222 of determining a blink frequency T1 and a yawning frequency T2 based on the eye and mouth tracking results;

Step 223, determining whether T1 is less than or equal to a preset blink frequency threshold;

specifically, when T1 is less than or equal to a preset blink frequency threshold, it is determined that a fatigue warning event occurs.

When T1 is greater than the preset blink frequency threshold, step 224 may be performed.

Step 224, determining whether T2 is greater than a preset yawning frequency threshold;

if the T2 is greater than or equal to a preset yawning frequency threshold value, determining that a fatigue early warning event occurs; if T2 is less than the predetermined yawning frequency threshold, step 221 is performed.

After the ECU determines the vibration mode, step 23, it may send a vibration instruction to the execution device based on the determined vibration mode, and control the execution device to operate in the matched vibration mode.
