Detailed Description
A vehicle safety warning system according to an embodiment of the present invention will be described with reference to the accompanying drawings, in which like elements are described with like reference numerals.
Fig. 1A is a schematic diagram of a projection warning area and a sensing warning area of a vehicle safety warning system according to an embodiment of the invention, fig. 1B is another schematic diagram of the projection warning area and the sensing warning area of the vehicle safety warning system according to an embodiment of the invention, fig. 2 is another schematic diagram of the projection warning area and the sensing warning area of the vehicle safety warning system according to an embodiment of the invention, and fig. 3 is a functional block schematic diagram of the vehicle safety warning system according to an embodiment of the invention.
The invention provides a vehicle safety warning system which is arranged on a vehicle. As shown in fig. 1A and 1B, the vehicle of the present embodiment is a container truck, but not limited thereto; in various embodiments, the vehicle safety warning system may also be mounted on, for example, a car, sports car, trailer, truck, recreational vehicle, or electric vehicle, or other mobile powered vehicle.
As shown in fig. 1A, a vehicle body C of a vehicle is generally divided into a front C1, a body C2, and a rear C3. The front C1 of the present embodiment refers to a vehicle body section including a cab, the vehicle body C2 refers to a vehicle body on the rear side of the cab (e.g., a section carrying a container), and the rear C3 refers to a vehicle body rear section. If the types of vehicles are different, the vehicle head C1 and the vehicle body C2 may include different body regions. The outer side of the vehicle body C may generally include a left vehicle body area a1, a right vehicle body area a2, a front vehicle body area A3, and a rear vehicle body area a 4. From the viewpoint of the driver on the driver's seat, the vehicle body left region a1 of the present embodiment may include a visual blind area BZ1 blocked by the a-pillar in the left region in front of the vehicle head C1, a visual blind area BZ2 in which the driver cannot see a vehicle coming behind on the driver's seat from the left side rear mirror C4, and an area in which the driver can see a vehicle coming behind or sideways with the naked eyes and the left side rear mirror C4; the vehicle body right side area a2 may include a vision blind area BZ3 blocked by the a-pillar in the right side area in front of the vehicle head C1, a vision blind area BZ4 in which the driver cannot see the coming vehicle behind on the driver's seat by the right side rear-view mirror C5, and an area in which the coming vehicle behind or to the side can be seen by the naked eye and the right side rear-view mirror C5; the vehicle body front area a3 includes a region directly in front of the vehicle head C1; and the vehicle body rear region a4 includes a region directly behind the vehicle rear C3.
The above-mentioned vision blind areas refer to: it is impossible for the driver of the vehicle to visually recognize the area outside the vehicle body C on the driver's seat without attaching other additional auxiliary devices such as a photographic lens, a mirror, or other devices. Therefore, other vehicles or pedestrians who enter the blind vision zones BZ1 to BZ4 cannot be seen by the driver, and are dangerous zones. Therefore, the blind visual regions (the left vehicle body region a1 and the right vehicle body region a2) are also dangerous regions when changing lanes or turning.
Referring to fig. 1A, fig. 1B and fig. 3, the vehicle safety warning system 1 of the present embodiment may include a cursor (light mark) projection unit 11, a sensing unit 12 and a control unit 13. In addition, the vehicle safety warning system 1 of the present embodiment further includes a sound unit 14, an image capturing unit 15 and a display unit 16.
The cursor projecting unit 11 has a plurality of cursor projecting components 111 (for the sake of simplicity, only one cursor projecting component 111 is shown in fig. 3), and these cursor projecting components 111 are disposed around the outer side of the vehicle body C of the vehicle. Here, the periphery of the outer side of the vehicle body C may include a preset projected warning area a, the projected warning area a of the present embodiment includes a vehicle left side area a1, a vehicle right side area a2, a vehicle front area A3 and a vehicle rear area a4, and the cursor projection unit 11 may emit light (visible light) to project (or irradiate) on the ground of the projected warning area a of the vehicle left side area a1, the vehicle right side area a2, the vehicle front area A3 and the vehicle rear area a 4. In various embodiments, the cursor projecting unit 11 can emit light (visible light) to project (or irradiate) the ground of the projected warning area a in the left vehicle area a1, and/or the right vehicle area a2, and/or the front vehicle area A3, and/or the rear vehicle area a 4.
In the present embodiment, the cursor projecting assemblies 111 may be respectively disposed on a front side of a vehicle C1 (e.g., on a front bumper of a front side C1, a metal plate of a front side C1, or a side surface of a front side C1), a left side rear mirror C4, a right side rear mirror C5, a front wheel frame C6, a rear wheel frame C7, two sides of a vehicle body C2, or a vehicle rear side C3 (e.g., on a rear bumper of a vehicle rear side C3 or a metal plate of a vehicle rear side C3), or a combination thereof, or other suitable places, for emitting light rays to project on the ground of the projected warning area a. As shown in fig. 1A, the cursor projecting component 111 of the present embodiment is respectively disposed on the front side C1, the left rear side C4, the right rear side C5, two sides of the vehicle body C and the rear side C3, but not limited thereto. In various embodiments, the number of the cursor projecting elements 111 may be determined according to the size (volume) or length of the vehicle. Wherein, a large-sized vehicle can be provided with a plurality of vehicles, and a small-sized vehicle can be provided with a plurality of vehicles. Regardless of the number of the devices, the projection range of the cursor projection component 111 at least covers the projection warning area a.
The light emitted by each cursor projecting component 111 can be projected on the ground of the projected warning area a continuously or in a flickering manner, so that the function of the driver of the vehicle as a safety warning by projecting and sensing the light and the object when the vehicle is driven is started or turned is provided. Specifically, depending on the usage situation, the cursor projecting component 111 may continuously or blinkingly emit light to project on the ground of the projected warning area a (the left vehicle body area a1, and/or the right vehicle body area a2, and/or the front vehicle body area A3, and/or the rear vehicle body area a 4). In the present embodiment, as shown in fig. 1B, the cursor projecting component 111 may project on the ground of the left vehicle area a1, the right vehicle area a2, the front vehicle area A3 and the rear vehicle area a4 to display a projecting area projecting the warning area a; alternatively, as shown in fig. 2, the cursor projecting unit 111 may project a marker line L around the vehicle body so as to define a projected warning area a including a vehicle body left area a1, a vehicle body right area a2, a vehicle body front area A3, and a vehicle body rear area a4 by the marker line L. The projected warning area a or the marking line L is a warning range between the vehicle and other surrounding vehicles and pedestrians during driving, traveling or turning, so that the TOO much attention is needed when the TOO much attention is paid to remind other vehicles or pedestrians to enter the projected warning area a or the marking line L, indicating that the TOO much attention is located in the visual blind area of the driver or is TOO close to the vehicle, and if the vehicle is rubbed and collided, the driver may not react immediately. Therefore, when the vehicle is in a driving state, a traveling state or a turning state, and the light emitted by the cursor projection component 111 continuously or in a flickering state is projected on the ground of the projection warning area a, the surrounding vehicles and pedestrians can take corresponding safety protection actions, such as being far away from the projection warning area a or the marking line L, so that the occurrence of danger is avoided. In some embodiments, the projected warning area a and the indication line L can be projected at the same time, but the invention is not limited thereto. The projected warning area a may not be a quadrilateral area, and may be an area formed by straight lines, arcs, or irregular lines, for example. The above-mentioned indication line L can be other lines besides straight line, such as arc line, or irregular line, or their combination, so as to enclose the projected warning area a.
In some embodiments, each cursor projecting element 111 may include a light source, or may include a light source and an optical element; the light source can be, for example but not limited to, a laser, or a light emitting diode, or a combination thereof, or other suitable light source; the optical element may be, for example, a lens, a polarizer, a brightness enhancement plate, or a mirror, or a combination thereof, and the present invention is not limited thereto. In addition, in some embodiments, the cursor projecting unit 11 may be combined with an existing lighting system of the vehicle, such as a headlight, a fog light, a tail light, a brake light, a turn signal, a left/right turn signal, and the like. For example, when the left-turn light is turned on, the light emitted by the cursor projection component 111 on the left side and the front side of the vehicle can be made to flash intermittently or rapidly to remind other vehicles or pedestrians on the left side and the front side of the vehicle to notice; when the brake lights are on, the light emitted by the cursor projecting component 111 behind the vehicle can be interrupted or quickly flickered synchronously to remind other vehicles or pedestrians behind to notice.
The sensing unit 12 has a plurality of sensing elements 121 (only one is shown in fig. 3 for simplicity), which are disposed around a vehicle body C (not shown). The vehicle further has a sensing alarm area B on the outer side of the vehicle body C, and each sensing element 121 can generate an alarm signal S1 when sensing an object in the sensing alarm area B. Here, the object may be another vehicle, a pedestrian, an obstacle, or the like. Specifically, in the embodiment, when an object enters the sensing alarm area B outside the vehicle body C, it indicates that the object is too close to the vehicle body C, and the sensing element 121 can output the alarm signal S1 when sensing the existence of the object.
The sensing components 121 of the sensing unit 12 may be disposed around the vehicle body C, for example, may be disposed at the front end C1 (e.g., at the front bumper of the front end C1, or the sheet metal of the front end C1, or the side of the front end C1), the left side rear mirror C4, the right side rear mirror C5, the front wheel frame C6, the rear wheel frame C7, the vehicle body C2, or the vehicle tail C3 (e.g., at the rear bumper of the vehicle tail C3, or the sheet metal of the vehicle tail C3), or other positions, or combinations thereof, without limitation. In some embodiments, each sensing element 121 may be disposed adjacent to each cursor projecting element 111. Here, the number of the sensing elements 121 can be determined according to the size (volume) or length of the vehicle, and a large vehicle can be installed in a larger number, and a small vehicle can be installed in a smaller number. Regardless of the number of the sensor units, the sensing range of the sensing element 121 at least covers the sensing alarm area B surrounding the outer side of the vehicle body C.
The sensing alarm area B of the present embodiment is a quadrilateral surrounding the outside of the vehicle as an example, but the actual situation may be different; in various embodiments, the sensing alert area B may have other shapes (e.g., including an arc shape or other shapes, or a combination thereof), as long as it is a surrounding area outside the vehicle body C, and it depends on the distance and angle or position of the sensing assembly 121 that needs to provide a safe sensing range. For example, the sensing alarm area B shown in fig. 2 is a straight line in the front and rear areas of the vehicle body C, but two sides of the vehicle body C are arc-shaped, because the two sides of the vehicle body C are dangerous areas during turning, the alarm area can be larger. Of course, the sensing alarm area B shown in fig. 2 is only illustrated and described, and when actually configured, the sensing alarm area B may have different shapes according to the use requirement.
It should be noted that the projected warning area a and the sensing warning area B may at least partially overlap. In the present embodiment, the projected warning area a (the left vehicle area a1, the right vehicle area a2, the front vehicle area A3, and the rear vehicle area a4) and the sensing warning area B are completely overlapped. In various embodiments, the sensing alert zone B may also be larger than the projected alert zone a, such as illustrated in fig. 2; alternatively, the sensing alert area B is smaller than the projecting alert area a, and is not limited. In addition, the distance between the periphery of the projected warning area a (the left vehicle area a1, the right vehicle area a2, the front vehicle area A3, and the rear vehicle area a4) and the vehicle body C may be greater than, equal to, or less than the distance between the periphery of the sensing warning area B and the vehicle body C, and the invention is not limited thereto. In some embodiments, the distance between the periphery of the projected warning area a (the left vehicle area a1, the right vehicle area a2, the front vehicle area A3, and the rear vehicle area a4) or the sensing warning area B and the vehicle body C may be at least 1 meter, 1.5 meters, 2 meters, or other distances, depending on the design requirements and/or the size of the vehicle body C.
In some embodiments, each sensing element 121 may, for example, include an infrared sensor and its receiver, or an ultrasonic sensor and its receiver, or a combination thereof. By using the sensing function of the infrared sensor and/or the ultrasonic sensor, it is possible to actively detect whether other vehicles or pedestrians are located in the sensing warning area B during the traveling or turning of the vehicle, so as to provide an active protection function, so that the driver, other vehicles or pedestrians can respond in real time, thereby avoiding danger.
Referring to fig. 3 again, the control unit 13 is coupled to and controls the cursor projecting unit 11 and the sensing unit 12, respectively, and can control the cursor projecting unit 11 and the sensing unit 12, respectively. The control unit 13 of the present embodiment is also coupled to and controls the sound unit 14, the image capturing unit 15 and the display unit 16, respectively. When each sensing element 121 senses that an object is in the sensing alarm region B, the output alarm signal S1 can be transmitted to the control unit 13, so that the control unit 13 can further perform a corresponding control action. The control unit 13 can control the sound unit 14 to emit a warning sound (e.g. a buzzer or a voice announcement) according to the warning signal S1, and change the warning sound according to the warning signal S1 that senses the sensing result in the warning area B, wherein the warning sound can be a voice sound (voice announcement) and/or a sound with different volume and frequency (e.g. change the volume and frequency of the buzzer).
In some embodiments, the sound unit 14 may be a speaker or a buzzer, which may be disposed inside the cab of the vehicle and/or on the periphery of the vehicle body C to emit a warning sound effect to prompt the driver of the vehicle and/or other vehicles or pedestrians in the sensing warning area B to perform judgment and handling (e.g., avoidance). In other words, if there are other vehicles or pedestrians located in the sensing warning area B, the control unit 13 can make the sound unit 14 (speaker or buzzer) send out warning sound according to the warning signal S1 to prompt the driver of the vehicle and/or other vehicles or pedestrians located in the sensing warning area B to take actions such as braking and/or avoiding; in addition, the control unit 13 can even automatically start the braking system of the vehicle to perform active braking assistance, thereby avoiding traffic accident damage. In addition, the sound unit 14 can further control the volume, the sound length, the sound frequency (high frequency, i.e. short interval time, indicating a sudden change, low frequency, i.e. long interval time, indicating a moderate change), or a combination thereof of the warning sound effect emitted by the sound unit 14 (a speaker or a buzzer) according to the distance between the object and the vehicle body (the distance between the object and the sensing element) sensed by the sensing element 121. In addition, the control unit 13 can also change the flashing frequency (fast and slow), and/or intensity (brightness), and/or color (e.g. blue or red) of the light emitted by the cursor projecting elements 111 according to the warning signal S1 for sensing the sensing result in the warning region B.
Fig. 4A to fig. 4E are schematic warning diagrams of different operation modes of the vehicle safety warning system according to an embodiment of the invention. In some embodiments, the actions of the cursor projecting unit 11 and the sensing unit 12 include, for example, but not limited to, the following six modes.
First mode (parking-after-drive mode): as shown in fig. 4A, when the vehicle is about to move forward from a stop, the light emitted by the cursor projection unit 11 can be projected on the projected warning area a (i.e. the left vehicle body area a1, the right vehicle body area a2, the front vehicle body area A3 and the rear vehicle body area a4), and the light projected on the projected warning area can be intermittently flashed for warning surrounding pedestrians and vehicles; the sensing element 121 continuously senses whether an object enters the sensing alarm region B.
Second mode (reverse mode): when the vehicle is going to reverse, please refer to fig. 4A again, the light emitted by the cursor projecting unit 11 can be projected in the projected warning areas of the rear area a4, the left area a1 and the right area a2 of the vehicle body (because the vehicle may also turn at the same time when reversing); alternatively, the light emitted by the cursor projecting unit 11 is projected only onto the projected warning area of the rear area a4 of the vehicle body, and the projected light may blink intermittently, if an obstacle (a person or an object) enters the rear, left or right sensing warning area B and is sensed by the sensing element 121, the light projected by the cursor projecting element 111 on the rear, left or right side of the vehicle body C will blink intermittently and faster to enhance the warning effect.
Third mode (turning mode): when the vehicle turns, for example, when the right turn signal is pressed, as shown in fig. 4B, the cursor projection unit 11 can emit light to project on the projected warning area (which can be linked with the signal indicator) of the vehicle right area a2 and the vehicle front area A3; alternatively, the light emitted by the cursor projecting unit 11 is projected only on the projected warning area of the right area a2 of the vehicle body, and the projected light is intermittently flickered, and the sensing element 121 simultaneously senses whether an object enters the sensed warning area B. If a pedestrian or an incoming vehicle enters the vehicle right area a2 and the vehicle front area A3 during the turning process and is sensed by the sensing element 121, the light projected by the cursor projecting element 111 corresponding to the vehicle right area a2 and the vehicle front area A3 will flash intermittently at a faster speed to enhance the warning effect. Of course, when the vehicle is going to turn left, the cursor projecting unit 11 can emit light to project on the left area a1 and the front area A3 of the vehicle body, or the projected warning area of the left area a1 of the vehicle body, and other operations can refer to the above-mentioned right turning.
Fourth mode (travel mode): as shown in fig. 4C, when another vehicle approaches and enters the sensing warning areas B on the left and right sides of the vehicle and is sensed by the sensing elements 121, the cursor projecting elements 111 on the two sides are activated to make the light projected on the left area a1 and the right area a2 of the vehicle body blink intermittently, so as to remind the coming vehicle of the driving distance.
Fifth mode (critical or failure mode): as shown in fig. 4D, when the vehicle is temporarily stopped (not turned off) or the vehicle is in a fault, all light rays emitted by the cursor projecting assembly 111 are intermittently flickered (the light rays can be synchronized with the fault warning light during the fault), so as to enhance the warning of surrounding pedestrians and vehicles; and the sensing element 121 can selectively turn on or off the sensing function.
Sixth mode (parking mode): as shown in fig. 4E, when the vehicle is parked on the roadside and turned off, for example, when the vehicle is parked near the right side, in addition to the sensing element 121 on the right side of the vehicle body C being temporarily disabled, the user can select to turn on or turn off the sensing elements 121 on the other three sides of the vehicle body C; when the sensing elements 121 on the other three sides of the vehicle body C are selected to be turned on, and a pedestrian or a vehicle enters the sensing warning area B on the three sides and is sensed by the sensing elements 121, the cursor projecting element 111 in the area is started to emit intermittent flashing light for warning the pedestrian or the vehicle.
The above six modes are only examples and are not intended to limit the present invention. In addition, different applications may have more different operation modes, depending on the needs of the user.
In addition, referring to fig. 3 and fig. 1A again, the image capturing unit 15 may be disposed at the periphery of the vehicle body C, and may capture the image located in the sensing warning area B, and the captured image may be transmitted to the control unit 13, so that the control unit 13 may control the display unit 16 to display the image located in the sensing warning area B according to the warning signal S1. Specifically, when other vehicles or pedestrians are located in the sensing warning area B and the control unit 13 receives the warning signal S1, the control unit 13 may enable the display unit 16 to display the object image (of course, a warning sound effect) according to the object image captured by the image capturing unit 15, so that the driver can see the vehicles or pedestrians located in the sensing warning area B from the display unit 16 to take corresponding actions to avoid the occurrence of car accidents. The image of the object may be a real image or a virtual image, and the display unit 16 may include an in-vehicle display (e.g., but not limited to, a console or an instrument panel of the cab) and/or a Head-up display (HUD), and the Head-up display may be, for example, but not limited to, a front windshield in front of the driver's seat. In this way, the head-up display technology matched with the optical suspension projection enables a driver to directly see the image of the object in the sensing warning area B on the front windshield without lowering the head or adjusting the visual focal length. In addition, the displayed image can be subjected to image recognition processing, and the original image can be displayed while the object subjected to image recognition processing is marked (for example, the object is marked by a frame line) so as to focus on the action of the object.
In some embodiments, when a plurality of image capturing units 15 are disposed on the periphery of the vehicle body C, each image capturing unit 15 may be disposed adjacent to each cursor projecting element 111 or each sensing element 121, for example. In addition, the display unit 16 and the image capturing unit 15 can be selected to be set according to the requirement of the user (vehicle).
Fig. 5 is a functional block diagram of a vehicle safety warning system according to another embodiment of the invention, and fig. 6 is a warning diagram of another operation mode of the vehicle safety warning system according to an embodiment of the invention.
Referring to fig. 5, a vehicle safety warning system 1a of the present embodiment is substantially the same as the vehicle safety warning system 1 of the previous embodiment. However, in order to prevent the door from being opened inadvertently and being hit by a vehicle coming from behind, the vehicle safety warning system 1a of the present embodiment further includes a door opening sensing unit 17, wherein the door opening sensing unit 17 is coupled to the control unit 13 and has a plurality of door opening sensing elements 171 (only one is shown in fig. 5 for simplicity). The doors of the vehicle may be respectively and correspondingly provided with at least one door opening sensing element 171, and the door opening sensing element 171 is disposed on the door and/or the door frame, and may be matched with various types of opening and closing switches, such as but not limited to a magnetic switch or a contact switch, or a combination thereof, or other types of door opening sensing switches, without limitation.
When one or more of the doors are opened, the at least one door opening sensing device 171 corresponding to the opened door may generate a door opening signal S2 and transmit the door opening signal S2 to the control unit 13, the door opening signal S2 may be used to activate the at least one sensing device 171 disposed on the same side of the opened door to sense the condition in the sensing alarm area B, and the at least one cursor projecting device 111 disposed on the same side of the opened door may also emit light to project on the same side and/or the projection alarm area of the rear vehicle body area a 4. The control unit 13 can change the flashing frequency and/or intensity and/or color of the light emitted by the cursor projecting component 111 corresponding to the opened door position according to the door opening signal S2. That is, by controlling at least one of the flashing frequency, the intensity and the color, other vehicles (including bicycles, locomotives, automobiles and the like) or pedestrians are reminded to notice that the door is about to be opened, so that the danger is avoided.
For example, as shown in fig. 6, when the driver ' S seat door at the left side of the vehicle is opened, the door opening sensing device 171 corresponding to the driver ' S seat door outputs a door opening signal S2 and transmits the door opening signal S2 to the control unit 13, the control unit 13 can change the flashing frequency of the light emitted by the cursor projecting device 111 corresponding to the position of the driver ' S seat door (left side of the vehicle body C) (for example, to flash irradiation, or to flash irradiation from flash irradiation to faster irradiation), and the control unit 13 can also control the sound unit 14 to emit a warning sound effect (for example, a buzzer or a voice broadcast alert) according to the door opening signal S2 to alert the coming vehicle or the passerby.
Specifically, the control unit 13 can control the warning sound effect generated by the sound unit 14 according to the door opening signal S2 and the sensing result in the sensing warning area B. When no pedestrian or vehicle coming from behind enters the sensing warning area B (and/or the rear area a4) on the left side of the vehicle body C, and the sensing element 121 does not sense the object in the sensing warning area B (and/or the rear area a4), the control unit 13 can make the volume of the warning sound effect emitted by the sound unit 14 smaller, and/or the duration of the sound longer, and/or the interval time between the front sound and the rear sound longer (moderate), in addition to maintaining the frequency and/or the intensity of the light emitted by the cursor projecting element 111 in the area. In addition, if there is a pedestrian or a vehicle coming from behind entering the sensing warning area B on the left side of the vehicle body C (and/or the rear area a4) and at least one sensing element 121 senses the object in the sensing warning area B (and/or the rear area a4), the control unit 13 may control the cursor projecting element 111 in the area to emit a faster intermittent flashing light, and make the volume of the emitted warning sound effect larger, and/or the duration of the sound shorter, and/or the interval time between the front and rear sounds shorter (sharper), so as to warn the vehicle or pedestrian.
In addition, in terms of the active safety protection design, the vehicle safety warning system 1a of the embodiment further includes a delayed-open door lock unit 18, the delayed-open door lock unit 18 is coupled to the control unit 13, and the delayed-open door lock unit 18 can unlock the vehicle door after delaying for a period of time according to the vehicle door opening signal S2. In other words, when the control unit 13 receives the door opening signal S2, it can be transmitted to the delayed-opening door lock unit 18, and the delayed-opening door lock unit 18 will unlock the door only if at least one sensing element 121 does not sense an object (an incoming car or a passerby) in the sensing alarm area B.
In a further active safety protection design, when the control unit 13 receives and transmits the door opening signal S2 to the delayed-opening door lock unit 18, the delayed-opening door lock unit 18 does not immediately unlock the door, but delays for a period of time (e.g., 2 to 3 seconds), and during the delay period, the at least one sensing element 121 senses in the sensing alarm area B, and does not sense an object (a vehicle or a passerby) to unlock the door. The design of delayed unlocking is to ensure that the driver or the passenger of the vehicle provided with the vehicle safety warning system can have buffer time for confirming the opening safety of the vehicle door again (visually confirming) before getting off.
If the left door of the vehicle is opened, during the delayed unlocking period, the at least one sensing element 121 disposed on the same side and/or the rear side of the left door can sense the condition in the sensing warning region B, and the at least one cursor projecting element 111 disposed on the same side of the left door can also emit light to project on the projected warning region on the left side of the vehicle body. When at least one sensing component 121 senses the existence of an object in the sensing warning area B on the left side of the vehicle body, the delayed door lock opening unit 18 can maintain the delayed door unlocking state according to the warning signal S1, thereby preventing a person from opening the door and causing a collision risk because the person does not notice the situation of an incoming vehicle or a pedestrian on the left side of the vehicle when getting off the vehicle. In addition, only when the sensing assembly 121 does not sense an incoming car or a pedestrian in the sensing alarm area B on the left side of the car body, the delayed door lock unit 18 can unlock the car door, so that a person can get off the car.
In the embodiment of the vehicle safety warning system 1a shown in fig. 5, the delayed opening door lock unit 18 is a separate component from the control unit 13, but not limited thereto, and in different embodiments, the delayed opening door lock unit 18 may be integrated into the control unit 13 as a single component. In addition, the control unit 13 of the vehicle safety warning system 1a of the embodiment may be coupled to a central control system 2 of the vehicle, and when the control unit 13 receives the warning signal S1, the warning signal S1 may be directly or after being processed, transmitted to the central control system 2, so that the central control system 2 may control the vehicle to actively decelerate or brake according to the warning signal S1, thereby avoiding injury to people or the vehicle. In addition, in different embodiments, the control unit 13 may also be integrated into the central control system 2 and be a built-in component of the central control system 2, so that the central control system 2 directly executes the above-mentioned control functions.
In addition, other technical contents of the vehicle safety warning system 1a of the present embodiment have been described in detail in the vehicle safety warning system 1 of the foregoing embodiment, and are not repeated herein.
In summary, in the vehicle safety warning system of the present invention, the cursor projecting unit is disposed around the vehicle body and can emit light to project onto the projected warning area set at the periphery of the vehicle body, the sensing unit can sense the object to emit a warning signal when the object is in the sensed warning area, and the control unit can generate a design corresponding to the control action according to the warning signal, so that the vehicle safety warning system of the present invention not only can provide the function of using the light to project and sense the object as a safety warning when the vehicle driven by the driver is running or turning, but also can provide an active protection function, so that the driver, other vehicles or pedestrians can respond in real time, thereby avoiding the occurrence of danger.
In addition, the vehicle safety warning system can also provide the function of active safety protection when a driver or a passenger opens the vehicle door, so that the danger caused by opening the vehicle door is avoided.
The foregoing is by way of example only, and not limiting. It is intended that all equivalent modifications or variations not departing from the spirit and scope of the present invention shall be included in the appended claims.
