Description

Technical Field

[0001] The present application relates to the field of automobile safety technology, and more specifically, to a vehicle blind spot monitoring and alarm method and system. Background Art

[0002] With the continuous development of intelligent technology, more active and passive safety technologies are being applied to automobiles. Safety has always been a very important point in the development of automobiles in various periods. In recent years, safety assisted driving technologies have emerged one after another, including: Autonomous Emergency Braking (AEB), Blind Spot Detection (BSD), Forward Collision Warning (FCW), Emergency Lane Keeping (ELK), etc., which detect the surrounding environment of the vehicle through cameras, millimeter-wave radars, etc. and identify targets with collision risks, and promptly remind the driver to pay attention to safety, or the vehicle autonomously brakes or avoids to ensure safety.

[0003] Currently, when a vehicle or cyclist approaches the vehicle or there is a vehicle in the blind spot of the vehicle, the safety assistance driving system will alert the driver through sound, rearview mirror warning light, etc. However, if the driver does not see the warning light, he will not know that there is a vehicle in the blind spot, and there will be a risk of scratching when changing lanes at this time.

[0004] Moreover, in functional scenarios such as BSD, only when the driver turns on the turn signal on the corresponding side and recognizes a vehicle in the blind spot, the vehicle will issue an alarm sound and alarm light to remind the driver that there is a vehicle in the blind spot on that side. When the vehicle does not turn on the turn signal or unconsciously approaches to one side, if there is a vehicle in the blind spot, the vehicle will not take alarm measures to remind the driver, which will also pose a risk of scratches.

[0005] In addition, the current blind spot monitoring range of BSD and other systems is mostly behind the vehicle's rearview mirror, on both sides of the vehicle and in the rear area. However, when the vehicle turns, the left and right A-pillar obstruction areas cannot be fully observed by the driver, but there are no corresponding early warning measures, which increases the risk of vehicle collision. Summary of the invention

[0006] The present application provides a vehicle blind spot monitoring and alarm method and system. When the safety assistance driving system detects a target vehicle with a collision risk in the blind spot, a first-level alarm is issued by lighting up at least one of the alarm lights on both sides of the instrument panel cover, so that the driver can observe the alarm information more easily and intuitively, thereby reducing the risk of scratches.

[0055] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0056] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0057] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0058] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0059] The present application provides a vehicle blind spot monitoring and alarm method and system. When the safety assisted driving system detects a target vehicle with a collision risk in the blind spot, at least one of the warning lights on both sides of the instrument panel cover is lit to issue a first-level alarm, so that the driver can more easily and intuitively observe the alarm information and reduce the risk of scratches. Furthermore, in the blind spot monitoring BSD or lane change management assistance system LCMA function scenario, regardless of whether the driver turns on the turn signal, as long as there is a target vehicle with a collision risk in the blind spot, and the steering wheel torque is greater than or equal to the first threshold, a second-level alarm will be issued, at least including flashing of the warning light and vibration of one side of the seat cushion of the main driver's seat. This method is not limited by whether the turn signal is turned on, and can effectively provide safety reminders for the driver. In addition, when the reversing side rear warning system finds a crossing vehicle with a collision risk or a target vehicle with a collision risk when the person in the car opens the car door, a safety reminder is given by flashing the warning lights on both sides of the instrument panel cover and vibrating the seat at the corresponding position. In addition, when the rear-end collision warning system detects a rear vehicle with a risk of collision, and when the reversing warning system detects that the vehicle is reversing too fast or too close to an obstacle, a three-level alarm is used to provide safety reminders to the driver to avoid accidents. Finally, if the radar at the A-pillar detects a dangerous vehicle or pedestrian when the vehicle is going straight or turning, the driver is also reminded through a second-level alarm. In summary, this application provides the driver or passengers in the car with a full range of effective safety reminders, reduces the incidence of safety accidents, and improves the user's car experience.

[0060] The vehicle blind spot monitoring and alarm method provided by the present application includes:

[0061] P1: If the vehicle's safety assistance driving system (such as blind spot monitoring BSD, door opening warning system (Door Open Warning, DOW), lane change management assistance system (Lane Change Management Assistance, LCMA), rear cross traffic alert system (Rear Cross Traffic Alert, RCTA), rear collision warning system (Rear Collision Warning, RCW) and other functional scenarios) detects a first target vehicle with a collision risk in the blind spot, a level 1 alarm is issued.

[0062] The first-level alarm includes at least: lighting up the alarm lights on both sides of the instrument panel cover or lighting up the alarm lights on the same side of the instrument panel cover as the first target vehicle. When the alarm lights are on, the light is soft and will not irritate the driver's eyes and interfere with the driver's sight. Setting up the alarm lights on the instrument panel cover allows the driver to observe the alarm information more easily and intuitively.

[0063] like Figure 1 As shown, a combination meter 200 is disposed in front of the steering wheel 100 , an instrument panel cover 300 is disposed above the combination meter 200 , and a first warning light 500 and a second warning light 400 are disposed on the left and right sides of the instrument panel cover 300 , respectively.

[0064] It is understandable that the first-level alarm may also include alarm modes such as sound alarm through a buzzer, voice reminder, etc.

[0065] As another embodiment, the blind spot monitoring and alarm method further includes a secondary alarm mechanism, which at least includes: controlling the first alarm light 500 and / or the second alarm light 400 on the instrument panel cover 300 to flash, and activating a vibrator on one side of the seat cushion of the driver's seat.

[0066] It is understandable that the secondary alarm may also include alarm modes such as sound alarm through a buzzer, voice reminder, etc.

[0067] like Figure 2 As shown, the driver's seat 600 includes a seat cushion 610 and a backrest 620. The left and right sides of the seat cushion 610 are respectively provided with a first vibrator 640 and a second vibrator 630. The first vibrator 640 and the second vibrator 630 serve as vibrators for the secondary alarm.

[0068] The secondary alarm mechanism specifically includes the following situations:

[0069] P2: If the blind spot monitoring BSD or lane change management assistance system LCMA of the vehicle detects that there is a second target vehicle with a collision risk in the blind spot, and the electric power steering system (Electric Power Steering, EPS) of the vehicle detects that the steering wheel torque is greater than or equal to the first threshold (for example, 0.8NM), a second-level alarm is issued. If the BSD / LCMA detects that there is a second target vehicle with a collision risk in the blind spot, but the steering wheel torque is less than the first threshold, a first-level alarm is issued, that is, the warning light on the instrument panel cover 300 in the same direction as the steering wheel torque is controlled to flash.

[0070] Among them, the second-level alarm includes at least:

[0071] P21: Control the warning light on the instrument panel cover 300 in the same direction as the steering wheel torque to flash. Specifically, if the steering wheel torque is to the left, the first warning light 500 on the left side of the instrument panel cover 300 flashes. If the steering wheel torque is to the right, the second warning light 400 on the right side of the instrument panel cover 300 flashes.

[0072] P22: Start the vibrator in the driver's seat cushion on the same side as the steering wheel torque. Specifically, if the steering wheel torque is to the left, the first vibrator 640 on the left side of the seat cushion is started. If the steering wheel torque is to the right, the second vibrator 630 on the right side of the seat cushion is started.

[0073] In this application, each threshold is a calibrated value. Table 1 gives an example of the application scenario and alarm method of the second-level alarm of this application. In the example shown in Table 1, for BSD / LCMA, its blind spot detection area is the overlapping area of ​​the following two: the lateral distance on both sides of the vehicle is within the range of 0~1.2m; the distance from the rear of the vehicle to the rear bumper of the vehicle is within the range of 0~40m.

[0074] P3: If the radar at the left or right A-pillar of the vehicle detects a third target vehicle or pedestrian with a collision risk when the vehicle is traveling straight or turning, and the first collision time is less than or equal to the second threshold (for example, 1s), a level 2 alarm is issued.

[0075] Among them, the second-level alarm includes at least:

[0076] P31: Control the warning light on the instrument panel cover 300 on the same side as the third target vehicle or pedestrian to flash;

[0077] P32: Activate the vibrator in the seat cushion 610 of the driver's seat 600 on the same side as the third target vehicle or pedestrian.

[0078] Figure 3 An example of the detection area of ​​the radar at the left and right A-pillars of the vehicle is shown, which is 0~15M in front of the left or right of the vehicle, and the measurement angle is 110°.

[0079] In the example shown in Table 1, when the vehicle is traveling straight or turning, its blind spot detection area is: 10 meters outside the left and right A-pillar blocking areas, and the monitoring angle is 110°.

[0080] P4: If the rear cross traffic alert system RCTA of the vehicle detects that there is a fourth target vehicle crossing from the left or right side behind the vehicle when the vehicle is reversing, and the second collision time between the vehicle and the fourth target vehicle is less than or equal to the third threshold (for example, 1S), a second-level alarm is issued.

[0081] Among them, the second-level alarm includes at least:

[0082] P41: Control the warning light on the left or right side of the instrument panel cover 300 to flash;

[0083] P42: Activate the vibrator on the left or right side of the seat cushion 610 of the driver's seat 600.

[0084] In the example shown in Table 1, for RCTA, its blind spot detection area is the overlapping area of ​​the following two areas: the lateral distance of 0 to 15 m on both sides of the vehicle; and the distance of 0.5 to 2.5 m behind the vehicle.

[0085] P5: If the vehicle's door opening warning system DOW detects that a door is opened and there is a fifth target vehicle with a collision risk behind the vehicle on the same side (for example, a cyclist or a motor vehicle overtaking), a level 2 alarm is issued.

[0086] Among them, the second-level alarm includes at least:

[0087] P51: Control the warning light on the instrument panel cover 300 on the same side as the door to flash;

[0088] P52: Activate the vibrator in the seat corresponding to the door position.

[0089] Specifically, if a fifth target vehicle with a collision risk is detected at the left rear when the left front door is opened, the warning light on the left side of the instrument panel cover 300 is controlled to flash, and the vibrator on the left side of the seat cushion of the main driver's seat is started.

[0090] If a fifth target vehicle with a collision risk is detected at the right rear when the right front door is opened, the warning light on the right side of the instrument panel cover 300 is controlled to flash, and the vibrator of the passenger seat is started at the same time.

[0091] If a fifth target vehicle with a collision risk is detected at the left rear when the left rear door is opened, the warning light on the left side of the instrument panel cover 300 is controlled to flash, and the vibrator of the left rear seat is started at the same time.

[0092] If a fifth target vehicle with a collision risk is detected at the right rear when the right rear door is opened, the warning light on the right side of the instrument panel cover 300 is controlled to flash, and the vibrator of the rear right seat is started at the same time.

[0093] In the example shown in Table 1, for DOW, its blind spot detection area is the overlapping area of ​​the following two: the lateral distance between the two sides of the vehicle is within the range of 0 to 1.2 m; the distance from the rear of the vehicle to the rear bumper is within the range of 0 to 30 m.

[0094] Table 1 Applicable scenarios and alarm methods of secondary alarm

[0095]

[0096] As another embodiment, the blind spot monitoring and alarm method further includes a three-level alarm mechanism. The three-level alarm at least includes: activating a vibrator in the backrest of the main driver's seat.

[0097] like Figure 2 As shown, a third vibrator 650 is provided on the backrest 620 of the driver's seat 600, serving as a third-level alarm vibrator.

[0098] It is understandable that the third-level alarm may also include alarm modes such as sound alarm through a buzzer, voice reminder, etc.

[0099] The three-level alarm mechanism specifically includes the following situations:

[0100] P6: If the rear-end collision warning system RCW of the vehicle detects that there is a risk of collision between the sixth target vehicle behind or behind the vehicle, and the third collision time is less than or equal to the fourth threshold (for example, 1.5S), a third-level alarm will be issued, which can effectively remind the driver that the rear vehicle is approaching rapidly and there is a risk of rear-end collision.

[0101] Among them, the third-level alarm at least includes: activating the vibrator in the backrest of the main driver's seat.

[0102] Table 2 gives an example of the applicable scenarios and alarm methods of the three-level alarm of the present application. In the example shown in Table 2, for RCW, its blind spot detection area is the overlapping area of ​​the following two: the lateral distance of 0~1m on both sides of the center axis of the vehicle; the distance of 0~40m from the rear bumper of the vehicle behind the vehicle.

[0103] P7: If the vehicle's reversing warning system (Parking Distance Control, PDC) detects that there is a risk of collision between the seventh target vehicle behind or behind the vehicle and the vehicle (for example, the vehicle is reversing too fast or the vehicle is too close to an obstacle), and the fourth collision time is less than or equal to the fifth threshold (for example, 1S) or the distance between the seventh target vehicle and the vehicle is less than the sixth threshold (for example, 0.5m), a third-level alarm is issued, which can effectively remind the driver to brake in time.

[0104] Among them, the third-level alarm at least includes: activating the vibrator in the backrest of the main driver's seat.

[0105] In the example shown in Table 2, for PDC, its blind spot detection area is the overlapping area of ​​the following two areas: within the lateral distance of 0 to 1.2 m on both sides of the center axis of the vehicle; within the distance of 0 to 0.5 m from the rear bumper of the vehicle behind the vehicle.
