Description

Vehicle safety warning system

The invention relates to a safety warning system, in particular to a multifunctional vehicle safety warning system.

When a vehicle driver is driving, his vision is restricted by the vehicle body. Generally, he can only understand the left, right, and rear conditions through the rear mirrors on both sides and the rear mirror of the vehicle. In order to pay attention to the conditions of the front vehicle, he cannot make sure to turn. When the head is used to determine the surrounding and the rear of the car, the driver’s blind spot of sight will naturally occur, which is the so-called "visual blind zone." When an oncoming car or pedestrian enters the blind spot of the vehicle, it is difficult or impossible for the driver to perceive the presence of each other through the sides and the rear mirror of the car.

In addition, when changing lanes or turning, most vehicle drivers can only "look" at the sides and/or the rear mirror of the car before changing lanes or turning. However, because of the vehicle’s A-pillar, B-pillar, and C-pillar Because the pillars block the line of sight, there are often blind spots in the line of sight, leading to miss the oncoming vehicles or pedestrians in the blind area. Even if flashing lights or audible warnings are installed beside the rear mirrors on both sides, it is impossible to actually know the arrival of the blind area and its surroundings. Vehicle or pedestrian conditions, especially large trailers, trucks, tour buses or container trucks, etc., because the driver’s seat is quite tall and the car body is quite long, the blind spots or blind spots in the line of sight are larger, which often results in blind spots or blind spots. A car accident that resulted in death or serious injury occurred.

The above-mentioned blind spot refers to the fact that for the driver of the vehicle, the driver cannot see the vehicle body from the driver's seat without additional auxiliary equipment (such as photographic lenses, mirrors or other equipment). The outside area. Therefore, other vehicles or pedestrians entering the blind areas BZ1 to BZ4 cannot be seen by the driver, and of course it is also a relatively dangerous area. Therefore, when changing lanes or turning, the blind spots (the left side area A1 and the right side area A2 of the vehicle body) are also more dangerous areas.

Please refer to FIG. 1A, FIG. 1B and FIG. 3 at the same time. The vehicle safety warning system 1 of this embodiment may include a light mark projection unit 11, a sensing unit 12, and a control unit 13. In addition, the vehicle safety warning system 1 of this embodiment may further include a sound unit 14, an image capturing unit 15 and a display unit 16.

The cursor projection unit 11 has a plurality of cursor projection components 111 (for the purpose of brevity, only one cursor projection component 111 is shown in FIG. 3 ), and the cursor projection components 111 are arranged around the outer side of the body C of the vehicle. Here, the four periphery of the outer side of the vehicle body C may include a preset projection warning area A. The projection warning area A of this embodiment includes the vehicle body left area A1, the vehicle right area A2, the vehicle front area A3, and the vehicle body The rear area A4, and the cursor projection unit 11 can emit light (visible light) to project (or irradiate) the projection warning area A in the left area A1, the right area A2, the front area A3, and the rear area A4 of the vehicle body ground. In different embodiments, the cursor projection unit 11 can emit light (visible light) to project (or irradiate) the left side area A1 and/or the right side area A2 of the vehicle body and/or the front area A3 of the vehicle body, and/or The ground of the projection warning area A in the rear area A4 of the vehicle body.

As shown in FIG. 1A, the cursor projection assembly 111 of this embodiment is set on the front C1, the left rear mirror C4, the right rear mirror C5, both sides of the body C, and the rear C3 as examples, but not Is limited. In different embodiments, the number of cursor projection components 111 can be determined according to the size (volume) or length of the vehicle. Among them, large vehicles can be installed more, and small vehicles can be installed fewer. Regardless of the number of installations, the projection range of the cursor projection component 111 must at least cover the projection warning area A.

The light emitted by each cursor projection component 111 can be continuously or flickeringly projected on the ground of the projection warning area A, so as to provide the driver with the light projection and sensing object as a safety warning when the vehicle driven by the driver starts or turns. Specifically, depending on the conditions of use, the cursor projection component 111 continuously or blinks to project light on the projection warning area A (the left area of the vehicle body A1, and/or the right area of the vehicle body A2, and/or the front area of the vehicle body A3, And/or on the ground in the area behind the vehicle body A4). In this embodiment, as shown in FIG. 1B, the cursor projection component 111 can project on the ground in the left area A1, the right area A2, the front area A3, and the rear area A4 of the vehicle body to display a projection warning. The projection area of area A; or, as shown in FIG. 2, the cursor projection component 111 can project a marking line L around the vehicle body, so as to be enclosed by the marking line L to include the left side area A1 and the right side of the vehicle body Area A2, the front area of the vehicle body A3, and the rear area of the vehicle body A4 are projected warning areas A. Among them, the projection warning area A or marking line L is the warning range of the vehicle and other vehicles and pedestrians around it when the vehicle is starting, moving or turning, and TOO reminds other vehicles or pedestrians to enter the projection warning area A or marking line L Be careful, indicating that it is already in the driver’s blind area or too close to the vehicle. If a collision occurs, the driver may not be able to react immediately. Therefore, when the vehicle is moving, moving or turning, the continuous or flashing light emitted by the cursor projection component 111 is projected on the ground of the projection warning area A, so that surrounding vehicles and pedestrians can take corresponding safety protection actions, such as staying away from the projection Warning area A or marking line L to avoid danger. In some embodiments, the projection warning area A and the marking line L can also be projected at the same time, and the present invention is not limited. The above-mentioned projection warning area A may not be a quadrilateral area, and it may be, for example, an area composed of straight lines, arcs, or irregular lines. In addition to the straight line, the above-mentioned marking line L may also be other lines, such as arcs, irregular lines, or a combination thereof, to enclose the projection warning area A.

In some embodiments, each cursor projection component 111 may include a light source, or may include a light source and an optical element; the light source may be, for example, but not limited to, a laser, or a light-emitting diode, or a combination thereof, or other suitable The light source; and the optical element can be, for example, a lens, a polarizing plate, a brightness enhancement plate, or a reflector, or a combination thereof, and the present invention is not limited. In addition, in some embodiments, the aforementioned cursor projection unit 11 can be combined with the original lighting system of the vehicle, such as headlights, fog lights, tail lights, brake lights, direction lights, left/right turn lights, etc. For example, when the left turn light is on, the light emitted by the cursor projection component 111 on the left and front of the vehicle can be synchronized to flash intermittently or quickly to remind other cars or pedestrians on the left and front to pay attention; when the brake lights are on, The light emitted by the cursor projection component 111 at the rear of the vehicle can be synchronized to flash intermittently or quickly to remind other vehicles or pedestrians at the rear to pay attention.

The sensing unit 12 has a plurality of sensing components 121 (for the sake of brevity, only one is shown in FIG. 3), which are arranged around the body C of the vehicle (not shown in the figure). The vehicle further has a sensing warning area B on the outer side of the vehicle body C, and each sensing component 121 can generate a warning signal S1 when an object is sensed in the sensing warning area B. Here, the object can be other vehicles, pedestrians, or obstacles. Specifically, in this embodiment, when an object enters the sensing warning area B outside the vehicle body C, it means that the object is too close to the vehicle body C, and the sensing component 121 can output when the object is detected. Warning signal S1.

The sensing components 121 of the sensing unit 12 can be arranged around the car body C, for example, can be respectively arranged on the front C1 of the vehicle (such as the front bumper of the front C1, or the sheet metal of the front C1, or the front C1 Side), left-side mirror C4, right-side mirror C5, front wheel frame C6, rear wheel frame C7, body C2, or rear C3 (for example, the rear bumper at the rear C3 or the sheet metal of the rear C3), or Other locations, or combinations thereof, are not limited. In some embodiments, each sensing component 121 may be adjacent to each cursor projection component 111. Here, the number of the sensing components 121 can still be determined according to the size (volume) or length of the vehicle. Large vehicles can be equipped with more, and small vehicles can be equipped with fewer. Regardless of the number of installations, the sensing range of the sensing component 121 must at least cover the sensing warning area B surrounding the outer side of the vehicle body C.

The sensing warning area B in this embodiment is a quadrilateral surrounding the outside of the vehicle as a schematic example, but the actual situation may be different; in different embodiments, the sensing warning area B may also have other shapes (for example, including arcs). Or other shapes, or a combination thereof), as long as it is the area outside the surrounding vehicle body C, and it depends on the distance and angle or position of the safe sensing range that different sensing components 121 need to provide. For example, for example, the sensing warning area B shown in FIG. 2B is a straight line in the front and rear areas of the vehicle body C, but is curved on both sides of the vehicle body C, because when turning, the two sides of the vehicle body C are More dangerous areas, therefore, the warning area can be larger. Of course, the sensing and warning area B shown in FIG. 2B is only for illustration and description. In actual setting, there can be different shapes of the sensing and warning area B according to the needs of use.

It is worth mentioning that the aforementioned projection warning area A and the sensing warning area B may at least partially overlap. In this embodiment, the projection warning area A (the vehicle body left area A1, the vehicle right area A2, the vehicle front area A3, and the vehicle rear area A4) and the sensing warning area B are completely overlapped as an example. In different embodiments, the sensing warning area B may also be larger than the projection warning area A, as shown in FIG. 2B; or, the sensing warning area B is smaller than the projection warning area A, which is not limited. In addition, the distance between the periphery of the projection warning area A (the left side area A1, the right side area A2, the front area A3, and the rear area A4 of the vehicle body) and the vehicle body C can be greater than, equal to, or smaller than the sensing warning area B The distance between the periphery of the vehicle body C and the vehicle body C is not limited by the present invention. In some embodiments, the projection warning area A (car body left area A1, car body right area A2, car body front area A3, car body rear area A4) or sensing the distance between the periphery of the warning area B and the car body C, for example It can be at least 1 meter, 1.5 meters, 2 meters, or other distances, depending on the design needs and/or the size of the car body C.

In some embodiments, each sensing component 121 may, for example, include an infrared sensor and its receiver, or an ultrasonic sensor and its receiver, or a combination thereof. The sensing function of infrared sensors and/or ultrasonic sensors can be used to actively detect whether there are other vehicles or pedestrians in the sensing warning zone B when the vehicle is moving or turning, so as to provide active protection , So that the driver, other vehicles or pedestrians can react immediately to avoid danger.

Please refer to FIG. 3 again, the control unit 13 is coupled to and controls the cursor projection unit 11 and the sensing unit 12 respectively, and can control the cursor projection unit 11 and the sensing unit 12 respectively. The control unit 13 of this embodiment is also coupled to and controls the sound unit 14, the image capture unit 15 and the display unit 16 respectively. When each sensing component 121 senses that there is an object in the sensing warning area B, the output warning signal S1 can be sent to the control unit 13 so that the control unit 13 can further perform corresponding control actions. Among them, the control unit 13 can control the sound unit 14 to emit a warning sound effect (such as a buzzer sound or a voice broadcast reminder) according to the warning signal S1, and change the warning sound effect according to the warning signal S1 of the sensing result in the warning area B to warn The sound effects can be language sounds (voice broadcast reminders) and/or sounds with different volume and frequency (for example, changing the volume and frequency of the buzzer).

In some embodiments, the sound unit 14 may be a loudspeaker or a buzzer, which may be arranged inside the cab of the vehicle and/or on the periphery of the vehicle body C to issue a warning sound effect to immediately remind the driver of the vehicle, and/or Other vehicles or pedestrians located in the sensing warning area B perform judgment and response processing (such as avoidance). In other words, if there are other vehicles or pedestrians in the sensing warning area B, the control unit 13 can make the sound unit 14 (speaker or buzzer) emit a warning sound effect according to the warning signal S1 to remind the driver of the vehicle and/ Or other vehicles or pedestrians located in the sensing warning zone B take actions such as braking and/or avoidance; in addition, the control unit 13 can even automatically activate the vehicle's braking system to perform active braking assistance to avoid car accident injuries. In addition, the sound unit 14 can further control the sound unit 14 (speaker or buzzer) to emit a warning sound effect according to the distance between the object and the vehicle body sensed by the sensing component 121 (the distance between the object and the sensing component) The volume of the sound, the length of the sound, the sound frequency (high frequency means short interval time, indicating rapidness; low frequency means long interval time, indicating relaxation), or a combination thereof. In addition, the control unit 13 can also change the flashing frequency (speed), and/or, the intensity (high or low brightness) of the light emitted by the cursor projection components 111 according to the alarm signal S1 of the sensing result in the sensing alarm area B, and / Or color (e.g. blue or red).

(Or passers-by), the door can be unlocked only when the door lock unit 18 is delayed.

In terms of further active safety protection design, when the control unit 13 receives and transmits the door opening signal S2 to the delayed opening of the door lock unit 18, the delayed opening of the door lock unit 18 does not unlock the door immediately, but delays for a period of time (for example, 2 ~3 seconds), and within the delay time, at least one sensing component 121 performs sensing in the sensing warning area B, and the door is unlocked when no object (an incoming vehicle or passerby) is sensed. Such a "delayed unlocking" design is to allow drivers or passengers of vehicles equipped with the vehicle safety warning system of the present invention to have a buffer time to reconfirm (visually confirm) the safety of the door opening before getting off the vehicle.

Assuming that the door on the left side of the vehicle is opened, at least one sensing component 121 arranged on the same side and/or behind the left side door can sense the condition in the warning area B during the period of delayed unlocking, and is arranged in At least one cursor projection component 111 on the same side of the left side door can also emit light at the same time to project on the projection warning area on the left side of the vehicle body. Wherein, when at least one sensing component 121 detects the presence of an object in the sensing warning area B on the left side of the vehicle body, the delayed opening door lock unit 18 can maintain the delayed door unlocking state according to the warning signal S1, thereby, It can avoid the risk of collision when people get off the vehicle and pay attention to the oncoming traffic or pedestrian conditions on the left side of the vehicle and open the door. In addition, only when the sensing component 121 does not sense incoming vehicles or pedestrians in the sensing warning area B on the left side of the vehicle body, the delayed opening of the door lock unit 18 can unlock the vehicle door and allow the person to get off the vehicle.

In the embodiment of the vehicle safety warning system 1a in FIG. 5, the delayed opening door lock unit 18 is a component independent of the control unit 13, but it is not limited to this. In different embodiments, the delayed opening door lock unit 18 It can also be integrated into the control unit 13 to become a single component. In addition, the control unit 13 of the vehicle safety warning system 1a of this embodiment can be coupled to a central control system 2 of the vehicle, and when the control unit 13 receives the warning signal S1, it can transmit the warning signal S1 directly or after processing. To the central control system 2, the central control system 2 can control the vehicle to actively decelerate or brake according to the warning signal S1, so as to avoid injury to personnel or vehicles. In addition, in different embodiments, the control unit 13 can also be integrated with the central control system 2 to be a built-in component of the central control system 2 so that the central control system 2 directly executes the aforementioned control functions.

In addition, other technical content of the vehicle safety warning system 1a of this embodiment has been described in detail in the vehicle safety warning system 1 of the foregoing embodiment, and will not be repeated here.

In summary, in the vehicle safety warning system of the present invention, the projection unit through the cursor is arranged around the car body, and can emit light to project on the projection warning area set on the periphery of the car body, and the sensing unit can sense objects A warning signal is issued when the warning area is sensed, and the control unit can generate a corresponding control action design according to the warning signal, so that the vehicle safety warning system of the present invention can not only provide the driver with light projection and light projection when driving or turning. In addition to the function of sensing objects as safety warnings, it can also provide active protection functions, allowing drivers, other vehicles or pedestrians to react immediately to avoid danger.

In addition, the vehicle safety warning system of the present invention can also provide the function of active safety protection for drivers or passengers when the door is opened, so as to avoid the danger caused by the opening of the door.
