Description
本發明關於一種安全警示系統,特別關於一種多功能的車輛安全警示系統。 The invention relates to a safety warning system, in particular to a multifunctional vehicle safety warning system.
車輛駕駛人在行駛的過程中,其視野受到車體的限制,一般只能透過兩側照後鏡及車內照後鏡了解左、右側與後方的狀況,為注意前方車況,也無法確實轉頭來確定四周及後方來車,自然產生駕駛人的視線死角,即所謂的「視覺盲區」。當來車或行人進入車輛的視覺盲區時,駕駛人是難以或無法透過兩側與車內照後鏡察覺到對方的存在。 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.
另外,當要變換車道或轉彎時,大部分的車輛駕駛人只能透過「瞄」一下兩側及/或車內照後鏡再變換車道或轉彎,但又因為車輛A柱、B柱、C柱阻擋視線的緣故,往往存在著視線盲點,導致漏看盲區內的來車或行人,即使是在兩側照後鏡旁加裝閃燈或聲響警示,也無法實際知道盲區及其周圍的來車或行人狀況,特別是大型拖車、貨車、遊覽車或貨櫃車等,由於駕駛座相當高,車體也相當長,因此,視線死角或盲區的範圍更大,導致常會因視線死角或盲區所導致的死亡或重傷的車禍發生。 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.
另外,車門開啟也是是常常造成車禍傷亡的因素,若車門開啟前未多加確認來車或行人,也可能因車門開啟使來車撞上或車門碰撞來車而發生事故。 In addition, door opening is also a factor that often causes injuries and deaths in car accidents. If the door is opened without more confirmation of incoming vehicles or pedestrians, an accident may occur due to the opening of the door and the collision of the incoming vehicle or the door collision.
因此,如何提供感知視線死角或盲區的狀況,並感知車門開啟的狀況,作為車輛駕駛人的輔助,已是重要課題。 Therefore, how to provide the perception of blind spots or blind spots in the line of sight and the opening of the door is an important issue as an aid to the driver of the vehicle.

如圖1A所示,一般來說,車輛的車體C可區分為車頭C1、車身C2及車尾C3。本實施例的車頭C1指的是包括駕駛室的車體部分,車身C2指的是駕駛室後側的車體(例如承載貨櫃的部分),而車尾C3指的是車體尾部。若車輛的型式不同時,車頭C1與車身C2所包括的車體區域可能不同。其中,車體C的外側一般可包括車體左側區域A1、車體右側區域A2、車體前方區域A3及車體後方區域 A4。以駕駛員在駕駛座上的觀點來看,本實施例的車體左側區域A1可包括車頭C1前方左側區域中被A柱擋住的視覺盲區BZ1、駕駛員在駕駛座上無法由左側照後鏡C4看見後方來車的視覺盲區BZ2,以及可以由肉眼及左側照後鏡C4看見後方或側面來車的區域;車體右側區域A2可包括車頭C1前方右側區域中被A柱擋住的視覺盲區BZ3、駕駛員在駕駛座上無法由右側照後鏡C5看見後方來車的視覺盲區BZ4,以及可以由肉眼及右側照後鏡C5看見後方或側面來車的區域;車體前方區域A3包括車頭C1的正前方區域;而車體後方區域A4包括車尾C3的正後方區域。 As shown in FIG. 1A, generally, the body C of a vehicle can be divided into a front C1, a body C2, and a rear C3. The front C1 of this embodiment refers to the vehicle body including the cab, the vehicle body C2 refers to the vehicle body on the rear side of the cab (for example, the portion carrying the container), and the rear C3 refers to the rear of the vehicle body. If the types of vehicles are different, the car body areas included in the front C1 and the body C2 may be different. Among them, the outer side of the car body C can generally include the left side area A1, the right side area A2, the front area A3 and the rear area of the vehicle body. A4. From the perspective of the driver in the driver’s seat, the left side area A1 of the vehicle body of this embodiment may include the blind area BZ1 blocked by the A-pillar in the left area in front of the front of the car C1, and the driver cannot use the left side mirror in the driver’s seat C4 sees the blind zone BZ2 of incoming vehicles from the rear, and the area where the rear or side cars can be seen by the naked eye and the left rear mirror C4; the right area of the car body A2 may include the blind zone BZ3 blocked by the A-pillar in the front right area of the car front C1 , In the driver's seat, the driver cannot see the blind zone BZ4 of the oncoming vehicle from the right rear mirror C5, and the area where the rear or side vehicles can be seen by the naked eye and the right rear mirror C5; the front area A3 of the car body includes the front C1 The area directly in front of the vehicle body; the rear area A4 includes the area directly behind the rear of the vehicle C3.
上述的視覺盲區指的是:對車輛的駕駛員來說,在沒有加裝其他額外輔助設備(例如攝影鏡頭、反射鏡或其他設備)的情況下,駕駛人在駕駛座上無法目視車體C外面的區域。因此,進入視覺盲區BZ1~BZ4的其他車輛或行人也無法被駕駛員看到,當然也是比較危險的區域。所以,在變換車道或轉彎時,視覺盲區(車體左側區域A1、車體右側區域A2)也是比較危險的區域。 The above-mentioned visual blind zone 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 zone BZ1~BZ4 cannot be seen by the driver, and of course it is also a more dangerous area. Therefore, when changing lanes or turning, the blind areas (the left side area A1 and the right side area A2 of the vehicle body) are also relatively dangerous areas.

The fifth mode (temporary stop or failure mode): as shown in Figure 4D, when the vehicle is temporarily parked (without flameout) or the vehicle fails, the light emitted by all the
第六種模式(停車模式):如圖4E所示,車輛停於路邊且熄火時,例如車輛靠右側停放時,除了車體C右側的感測組件121暫時停止功用外,使用者可選擇開啟或關閉車體C其他三側的感測組件121;當選擇開啟車體C其他三側的感測組件121,且有行人或車輛進入這三側的感測警示區域B內而被感測組件121感測到時,則啟動該區域的光標投射組件111發出間斷閃爍的光線,用於警告行人或車輛。
The sixth mode (parking mode): as shown in Figure 4E, when the vehicle is parked on the side of the road and turned off, for example, when the vehicle is parked on the right side, the user can choose to temporarily stop the function of the
上述的六種模式只是舉例,不可用以限制本發明。此外,不同的應用可以有更多的不同運作模式,視使用者的需求而定。 The above-mentioned six modes are only examples and cannot be used to limit the present invention. In addition, different applications can have more different operating modes, depending on the needs of users.
另外,請再參照圖3及圖1A所示,影像擷取單元15可設置於車體C外圍,並可擷取位於感測警示區域B內的影像,而擷取到影像可傳送至控制單元13,使得控制單元13可同時依據警示訊號S1控制顯示單元16顯示位於感測警示區域B內的影像。具體來說,有其他車輛或行人位於感測警示區域B內而控制單元13接收到警示訊號S1時,控制單元13可依據影像擷取單元15擷取到的該物件影像而使顯示單元16顯示該物件影像(當然也有警示音效),讓駕駛員可以由顯示單元16中看見位於感測警示區域B內的車輛或行人,以採取因應的動作,避免車禍的發生。其中,上述該物件的影像可為真實影像或虛擬影像,而顯示單元16可包括車內顯示器及/或抬頭顯示器(Head up display,HUD),車內顯示器可例如但不限於位於駕駛室的中控台或儀錶板上,而抬頭顯示器可例如但不限於位於駕駛座前方的前擋玻璃。於此,搭配光學懸浮投影的抬頭顯示器技術讓駕駛員可以不必低頭,不必調整視覺焦距就可直接在前擋玻璃上看到位於感測警示區域B內的該物件的影像。另外,顯示的影像可先經過影像辨識處理,則顯示時也可顯示原影像同時將經影像辨識處理後的該物件標示出來(例如以框線標示出該物件),以便於關注該物件的動作。
In addition, please refer to FIG. 3 and FIG. 1A again. The
在一些實施例中,當在車體C外圍設置多個影像擷取單元15時,各影像擷取單元15例如可鄰設於各光標投射組件111或各感測組件121。此外,前述的顯示單元16及影像擷取單元15可視使用者(車輛)的需求而選擇是否設置。

圖5為本發明另一實施例的車輛安全警示系統的功能方塊示意圖,而圖6為本發明一實施例的車輛安全警示系統另一作動模式的警示示意圖。 FIG. 5 is a functional block diagram of a vehicle safety warning system according to another embodiment of the present invention, and FIG. 6 is a warning diagram of another operation mode of the vehicle safety warning system according to an embodiment of the present invention.
請參照圖5所示,本實施例的車輛安全警示系統1a與前述實施例的車輛安全警示系統1大致相同。不過,為了防止車門打開時不注意而被後方來車撞擊的問題,本實施例的車輛安全警示系統1a更可包括一車門開啟感測單元17,車門開啟感測單元17與控制單元13耦接,並具有多個車門開啟感測組件171(為簡潔目的,圖5只繪示一個)。其中,車輛的多個車門可分別對應設置至少一個車門開啟感測組件171,而車門開啟感測組件171設置於車門及/或門框上,並可配合各種車型結構而搭配不同型態的開閉合開關,例如但不限於磁力開關或接觸開關、或其組合、或其他形態的車門開啟感測開關,並不限制。
Please refer to FIG. 5, the vehicle safety warning system 1a of this embodiment is substantially the same as the vehicle
當多個車門的其中之一或多個被開啟時,對應於被開啟車門的至少一車門開啟感測組件171可產生一車門開啟訊號S2並傳送至控制單元13,該車門開啟訊號S2可用以啟動設置於被開啟車門的同一側的至少一感測組件171感測感測警示區域B內的狀況,且設置於被開啟車門的同一側的至少一光標投射組件111也可發出光線投射在同一側及/或車體後方區域A4的投射警示區域。其中,控制單元13可依據車門開啟訊號S2而改變對應於被開啟車門位置的光標投射組件111所發出光線的閃爍頻率及/或強度及/或顏色。也就是說,藉由控制閃爍頻率、強度、顏色至少其中之一,提醒其他車輛(包括自行車、機車、汽車等)或行人注意車門即將被開啟,避免發生危險。
When one or more of the plurality of doors is opened, at least one door
舉例來說,如圖6所示,當車輛左側的駕駛座車門被開啟時,對應設置於駕駛座車門的車門開啟感測組件171會輸出車門開啟訊號S2並傳送至控制單元13,控制單元13除了可改變對應於駕駛座車門位置(車體C左側)的光標投射組件111發出光線的閃爍頻率外(例如變成閃爍照射;或由閃爍照射變成更快速的閃爍照射),控制單元13還可依據車門開啟訊號S2控制聲音單元14發出警示音效(例如蜂鳴聲或語音播報提醒),以提醒來車或路人注意。
For example, as shown in FIG. 6, when the driver's door on the left side of the vehicle is opened, the door
具體來說,控制單元13可依據車門開啟訊號S2及感測警示區域B內的感測結果,控制聲音單元14所發出的警示音效。其中,當沒有行人或後方來車進入車體C左側的感測警示區域B(及/或車體後方區域A4)內,感測組件121在感測警示區域B(及/或車體後方區域A4)內未感測到該物件時,則除了維持該區域的光標投射組件111發出光線的頻率及/或強度外,控制單元13可以使聲音單元14所發出的警示音效的音量較小、及/或聲音持續時間較長、及/或前後聲間的間隔時間長(緩和)。另外,若有行人或後方來車進入車體C左側的感測警示區域B內(及/或車體後方區域A4)且至少一個感測組件121在感測警示區域B(及/或車體後方區域A4)內感測到該物件時,則控制單元13可控制該區域的光標投射組件111發出更快速的間斷閃爍光線,並且使所發出的警示音效的音量較大、及/或聲音持續時間較短、及/或前後聲間的間隔時間較短(較急促),用於警告來車或行人。
Specifically, the
此外,在主動安全防護設計上,本實施例的車輛安全警示系統1a更可包括一延遲開啟門鎖單元18,延遲開啟門鎖單元18與控制單元13耦接,且延遲開啟門鎖單元18可依據上述的車門開啟訊號S2延遲一段時間後才會解鎖車門。換句話說,當控制單元13接收到車門開啟訊號S2時可傳送至延遲開啟門鎖單元18,且在至少一感測組件121在該感測警示區域B內並未感測到物件(來車或路人)的前提,延遲開啟門鎖單元18才會進行車門解鎖。
In addition, in terms of active safety protection design, the vehicle safety warning system 1a of this embodiment may further include a delayed opening
更進一步的主動安全防護設計上,當控制單元13接收並傳送車門開啟訊號S2到延遲開啟門鎖單元18時,延遲開啟門鎖單元18並不會立即解鎖車門,而是延遲一段時間(例如2~3秒),且於該段延遲時間內,至少一感測組件121在感測警示區域B內進行感測,並未感測到物件(來車或路人)才會進行車門解鎖。這樣的「延遲解鎖」設計,是為了讓安裝有本發明車輛安全警示系統的車輛的駕駛或乘客,在下車前能夠有再次確認(目視確認)車門開啟安全性的緩衝時間。
In terms of further active safety protection design, when the
假設車輛左側的車門被開啟,在延遲解鎖的該段時間內,設置於左側車門的同一側及/或後方的至少一個感測組件121可以感測感測警示區域B內的狀況,並且設置於左側車門同一側的至少一個光標投射組件111也可同時發出光線投射在車體左側的投射警示區域。其中,當至少一個感測組件121在車體左側的感測警示區域B內感測到有物件存在時,則延遲開啟門鎖單元18可依據警示訊號S1維持延遲車門解鎖的狀態,藉此,可避免人員下車時末注意車輛左側的來車或行人狀況而開啟車門、發生碰撞危險。此外,只有感測組件121在車體左側的感測警示區域B內沒有感測到來車或行人時,延遲開啟門鎖單元18才可解鎖車門,讓人員可以下車。
Assuming that the door on the left side of the vehicle is opened, at least one
在圖5的車輛安全警示系統1a的實施例中,延遲開啟門鎖單元18為獨立於控制單元13的構件,然並不以此為限,在不同的實施例中,延遲開啟門鎖單元18也可整合於控制單元13中而成為單一構件。另外,本實施例的車輛安全警示系統1a的控制單元13可耦接於車輛的一中央控制系統2,並且,當控制單元13接收到警示訊號S1時,可以將警示訊號S1直接或處理後傳送至中央控制系統2,使中央控制系統2可依據警示訊號S1控制車輛主動減速或煞車,避免造成人員或車
輛的傷害。另外,在不同的實施例中,控制單元13也可以整合於中央控制系統2而為中央控制系統2的內建組件,以由中央控制系統2直接執行上述的的控制功能。
In the embodiment of the vehicle safety warning system 1a in FIG. 5, the delayed opening
此外,本實施例的車輛安全警示系統1a的其他技術內容已於前述實施例的車輛安全警示系統1中詳述,在此不再贅述。
In addition, other technical content of the vehicle safety warning system 1a of this embodiment has been described in detail in the vehicle
綜上所述,在本發明的車輛安全警示系統中,透過光標投射單元設置於車體的四周圍,並可發出光線投射在車體外圍設定的投射警示區域,而感測單元可感測物件在感測警示區域內時發出警示訊號,且控制單元可以依據警示訊號產生對應控制作動的設計,使得本發明的車輛安全警示系統除了可提供駕駛員所駕車輛在開動或轉彎時以光線投射及感測物件作為安全警示的作用外,更可提供主動防護的功能,讓駕駛員、其他車輛或行人可以即時反應,避免危險的發生。 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.
另外,本發明的車輛安全警示系統還可以提供駕駛或乘客在車門開啟時,主動安全防護的功能,避免車門開啟所造成的危險發生。 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.
