本發明是有關於一種資料分析技術,且特別是有關於一種位置的評估方法、駕駛行為的分析方法及駕駛管理系統。The present invention relates to a data analysis technology, and in particular, to a location evaluation method, a driving behavior analysis method and a driving management system.
車隊產業的工作條件造成司機勞動力高齡化和司機流動率高等問題。近年來,疫情使全球的物流產業需求急遽增加,需要顧聘更多新司機來解決大量的配送業務。因此,提升新手司機的教育訓練的重要性,不僅是關乎到司機的安全,也影響到車隊的經營(例如,因罰單或車損造成成本上揚)。Working conditions in the fleet industry have resulted in problems such as an aging workforce and high driver turnover. In recent years, the pandemic has dramatically increased demand for the global logistics industry, requiring the hiring of more new drivers to handle a large number of delivery operations. Therefore, the importance of improving the education and training of novice drivers is not only related to driver safety, but also affects fleet operations (for example, costs due to fines or vehicle damage).
司機短缺問題日益嚴重,有些國家甚至開放外國司機加入,以填補司機不足的缺口。當司機抵達新國度時,可能因不熟悉交通狀況而造成配送效率低落。若配送範圍在都市區域,新手司機尋找停車送貨的地點更加困難。The driver shortage problem is becoming increasingly serious. Some countries have even opened up to foreign drivers to fill the gap. When drivers arrive in a new country, they may be unfamiliar with the traffic conditions, resulting in low delivery efficiency. If the delivery range is in an urban area, it is even more difficult for novice drivers to find a place to park and deliver the goods.
有鑑於此,本發明實施例提供一種位置的評估方法、駕駛行為的分析方法及駕駛管理系統,可自動推薦停車位置並決定駕駛行為的優劣。In view of this, the embodiments of the present invention provide a location evaluation method, a driving behavior analysis method and a driving management system, which can automatically recommend parking locations and determine the quality of driving behavior.

The positioning record is a record of one or more timestamps and the corresponding vehicle positions. The current position of the vehicle can be determined based on the positioning signal of the
處理器16可依據定位紀錄決定車輛的停留時間。例如,處理器16每間隔特定時間(例如,1分鐘、3分鐘或5分鐘)確認車輛的位置是否變化或變化在容許範圍(相關於定位裝置12或感測器11的誤差)內。若位置不變或位置的變化在容許範圍內,則處理器16累計停留時間。The
車載裝置10的處理器16可依據車內影像決定車輛內的乘客是否離開座位。依據任務類型,辨識的乘客可以是駕駛座上的乘客。處理器16可應用已知的神經網路或特徵比對的影像辨識技術判斷乘客是否離開座位。例如,駕駛座上未偵測到人。The
車載裝置10的處理器16可依據停留時間及車內影像的決定結果決定停車狀態。例如,若目標座位(例如,駕駛座)上的乘客離開座位且/或車輛的停留時間超過一定時間(例如,3分鐘、5分鐘或10分鐘,並可能相關於統計的送貨時間),則處理器16可決定車輛為停車狀態。The
在一實施例中,車載裝置10的處理器16可判斷車輛的當前位置是否與預計停留點相距特定距離(例如,100、300或500公尺)內,以輔助確認停留狀態。在一實施例中,處理器16透過感測器11的感測資料決定車輛是否熄火。例如,車上診斷系統接收到停止供電的訊號,以輔助確認停留狀態。In one embodiment, the
在一實施例中,感測資料包括定位紀錄及車外影像。車外影像可以是針對車輛前方或四周的影像。In one embodiment, the sensing data includes positioning records and external vehicle images. The external vehicle images may be images of the front or surrounding areas of the vehicle.
例如,圖5是依據本發明一實施例的停車狀態的示意圖。請參照圖5,車外影像是車輛前方的影像。反應於停車狀態,處理器16可依據該定位紀錄中的當前位置、車外影像及時戳,以定義為停車狀態下的感測資料。例如,當前位置、車外影像及時戳組合成地理戳(GeoStamp)。地理戳代表車輛在特定時間位於特定位置停車且具有車外影像。處理器16可透過通訊收發器13傳送這停車狀態下的感測資料給伺服器30。For example, FIG5 is a schematic diagram of a parking state according to an embodiment of the present invention. Referring to FIG5 , the external image is an image in front of the vehicle. In response to the parking state, the
在其他實施例中,車載裝置10也可定時或反應於觸發條件而傳送感測資料至伺服器30,並可透過伺服器30實現停車狀態的決定。也就是,伺服器30執行步驟S420。In other embodiments, the vehicle-mounted
於步驟S430中,伺服器30的處理器36取得停車狀態下的感測資料對應的停車位置類別。In step S430, the
在一實施例中,停車位置類別包括建議停車類別、注意停車類別及危險停車類別。建議停車類別符合交通規範。“推薦”代表這個車位是合法的,例如、路邊停車格、停車場的停車格、卸貨倉庫的碼頭空地等。注意停車類別不符合交通規範但對應事故風險(相關於事故的發生率)小於風險門檻值。例如,“注意”代表這地點並非正常適合停車地點,但是可以進行臨停的停車地點。例如、黃線或者空地。危險停車類別不符合交通規範且對應事故風險未小於風險門檻值。“危險”屬於違法且具有肇事風險的停車地點。例如,紅線區域。中文是重力加速度嗎?XDIn one embodiment, the parking location categories include recommended parking categories, caution parking categories, and dangerous parking categories. It is recommended that parking categories comply with traffic regulations. "Recommended" means that the parking space is legal, such as roadside parking spaces, parking spaces in parking lots, open spaces at the docks of unloading warehouses, etc. Note that the parking category does not comply with traffic regulations but the corresponding accident risk (related to the occurrence rate of accidents) is less than the risk threshold. For example, "Caution" means that this location is not a normal parking location, but it is a temporary parking location. For example, yellow line or open space. The dangerous parking category does not comply with traffic regulations and the corresponding accident risk is not less than the risk threshold. "Danger" refers to parking locations that are illegal and pose a risk of causing an accident. For example, the red line area. Does Chinese mean acceleration of gravity? XD
在一實施例中,停車位置類別還包括其他/不建議停車類別。例如,“其他/不建議”是系統無法辨識的地點、或無劃黃線或紅線的單行道。然而,停車位置類別還可能有其他變化,並可依據應用者的需求而變更。In one embodiment, the parking location categories also include other/not recommended parking categories. For example, "Other/Not Recommended" is a location the system doesn't recognize, or a one-way street without yellow or red lines. However, there may be other variations to the parking location categories and may be changed based on the user's needs.
在一實施例中,伺服器30的處理器36可依據分類規則決定感測資料對應的初始類別。分類規則相關於停車合法性。分類規則可參考政府公開合法停車地點資料庫、道路條例規定及各車隊司機或特定區域內司機累積的停車地點資料。初始類別是那些停車位置類別中的一者。也就是,伺服器30的處理器36依據分類規則判斷停車狀態下的感測資料屬於停車位置類別中的何者。In one embodiment, the
例如,針對建議停車類別:這地點固定為超過一定比例(例如,百分之25、30或50)的司機停車地點、車外影像偵測出有停車格特徵或車外影像內有其他車輛超過特定時間(例如,3、5或10分鐘)處於停止狀態,且這地點與送貨地點相距特定距離(例如,50、100或200公尺)內。For example, for the recommended parking category: this location is fixed as a driver parking location with a certain percentage (e.g., 25, 30, or 50%), the external image detects parking space features, or other vehicles in the external image are parked for more than a specific time (e.g., 3, 5, or 10 minutes), and this location is within a specific distance (e.g., 50, 100, or 200 meters) from the delivery location.
針對注意停車類別:車外影像所偵測到的道路或路旁特徵屬於該國交通規範內許可臨時短暫停車;或者,這地點無其他司機停放前例,這地點非停車格,且這地點與送貨地點相距一定距離(例如,300公尺以上);車輛停放在停車格,但距離送貨地點超過一定範圍(例如,500公尺以上);這地點為空地、無其他司機停放之紀錄且距離送貨地點一定之距離(例如,200公尺以上);這地點於送貨途中距離停車前超過一定時間,例如,車輛一個小時內皆無遇到其他路上行進之車輛。Regarding the parking categories to be noted: the road or roadside features detected by the vehicle's external image are permitted for temporary short-term parking within the country's traffic regulations; or, there is no previous record of other drivers parking at this location, this location is not a parking space, and this location is a certain distance away from the delivery location (for example, more than 300 meters); the vehicle is parked in a parking space, but the distance to the delivery location exceeds a certain range (for example, more than 500 meters); this location is an open space, there is no record of other drivers parking, and it is a certain distance away from the delivery location (for example, more than 200 meters); this location is more than a certain time away from the parking during the delivery, for example, the vehicle has not encountered any other vehicles on the road within an hour.
針對危險停車類別:這地點曾經有司機停放紀錄,但是車外影像偵測無任何可停車之道路特徵。例如,無停車格,且附近無其他車輛停放超過一定時間(例如,1、3或5分鐘);這地點為單行道但是道路明顯大於一般道路(例如,超過1.5倍道之寬度)。For the dangerous parking category: There has been a record of drivers parking at this location, but the external image detection does not show any road features that can be parked. For example, there are no parking spaces and no other vehicles parked nearby for more than a certain period of time (e.g., 1, 3, or 5 minutes); the location is a one-way street but the road is significantly larger than an ordinary road (e.g., more than 1.5 times the width of the road).
針對其他/不建議停車類別:這地點無法被辨識是否可停車(例如,不屬於前述那些類別);距離送貨地點超過一定距離(例如,800公尺以上);這地點經比對圖資及車外影像之道路特徵後認定屬於禁止停車地點(例如,人行道)。For other/not recommended parking categories: This location cannot be identified as parking (for example, it does not belong to the aforementioned categories); it is more than a certain distance from the delivery location (for example, more than 800 meters); this location has been compared with map information and The road features in the image outside the vehicle are then determined to be a no-parking location (for example, a sidewalk).
在一實施例中,車輛的路線已決定。路線是由導航系統針對一個或更多個停留點的導航路徑或是經輸入操作編輯的路徑。停留點例如是送貨地點、景點或餐廳。處理器16可取得停留點的評估範圍(例如,半徑300公尺、500公尺或1公里)內的街景影像。例如,透過通訊收發器13下載街景影像。接著,處理器16可透過基於神經網路或特徵比對的影像辨識技術判斷停車格或空地,或者透過通訊收發器13傳送至伺服器30並藉由伺服器30辨識停車格、空地或其他停車位。這些停車位可結合其位置資訊並供後續審核。In one embodiment, the vehicle's route is determined. A route is a navigation path for one or more stop points by the navigation system or a path edited by input operations. Stopping points are, for example, delivery locations, attractions or restaurants. The
在一實施例中,停車格、空地或其他停車位可以是透過輸入裝置(圖未示)接收使用者在檢視器上針對導航圖資/街景影像的辨識操作所得出。這些停車位可結合其位置資訊並供後續審核。In one embodiment, parking spaces, open spaces or other parking spaces may be obtained by receiving the user's recognition operation on the navigation map/street view image on the viewer through an input device (not shown). These parking spaces can be combined with their location information and reviewed later.
伺服器30的處理器36可取得初始類別的審核結果。審核結果可以是透過輸入裝置(圖未示)接收使用者(例如,車隊管理者或資料處理人員)在檢視器上針對初始類別的標記操作所得出。標記操作可以是確認初始類別或修改初始類別成為另一個停車位置類別。The
例如,圖6是依據本發明一實施例的停車位置類別的示意圖。請參照圖6,檢視器(透過車載裝置10、伺服器30或遠端裝置的顯示器實現)可呈現根據初始類別(例如,停車位置類別可以是建議類別PT1、注意類別PT2及/或危險類別PT3的停車位置)分類的影像(例如,車外影像)。例如,屬於建議類別PT1、注意類別PT2及危險類別PT3的停車位置的影像IM11~IM14、IM21、IM31、IM32分別位於檢視器所顯示的使用者介面中的不同列,且使用者介面透過類別名稱(如圖所示的“建議”、“注意”、“危險”)區別不同類型的影像。建議類別PT1的影像IM11~IM14的內容可能是車輛位於車格、路邊無畫線區域或空地。注意類別PT2的影像IM21的內容可能是車輛位於暫停區域或指定時段停車區域。而危險類別PT3的影像IM31、IM32的內容可能是車輛位於禁停線上、人行道或公車停靠區。For example, FIG. 6 is a schematic diagram of parking location categories according to an embodiment of the present invention. Referring to FIG. 6 , the viewer (implemented through the display of the vehicle-mounted
須說明的是,在其他實施例中,處理器36也可能是將初始類別直接作為停車位置類別而未經審核,或者完全由標記操作來決定停車位置類別。It should be noted that in other embodiments, the
於步驟S440中,伺服器30的處理器36依據停車位置類別及感測資料訓練位置建議模型。In step S440, the
具體而言,位置建議模型用於建議停車位置,且位置建議模型是透過機器學習演算法所訓練。機器學習模型/演算法(例如,應用已知的神經網路、支援向量機(Support Vector Machine,SVM)、或隨機森林(Random Forest))可分析訓練樣本以自中獲得規律,從而透過規律對未知資料預測。而位置建議模型即是經學習後所建構出的機器學習模型,並據以對待評估資料(例如,感測資料)推論所屬的停車位置類別或推薦的停車位置。將停車定點區分成適合停車、臨時停車或高危險停車地點(例如,推薦、注意或危險等停車位置類別),透過大數據分析及影像判斷結果,自動歸納並逐漸建立適合停車地點的資料庫,以便後續最為推薦新手駕駛的停留地。值得注意的是,由於停車地點為一個區域概念,並非固定位置,因此需要透過數據分析及學習,才能逐步建立推薦停車區域及範圍。Specifically, the location recommendation model is used to recommend parking locations, and the location recommendation model is trained by a machine learning algorithm. The machine learning model/algorithm (for example, applying a known neural network, support vector machine (SVM), or random forest) can analyze training samples to obtain rules from them, thereby predicting unknown data through the rules. The location recommendation model is the machine learning model constructed after learning, and is used to infer the parking location category or recommended parking location based on evaluation data (for example, sensor data). The parking spots are divided into suitable parking spots, temporary parking spots or high-risk parking spots (for example, recommended, cautionary or dangerous parking spots). Through big data analysis and image recognition results, the database of suitable parking spots is automatically summarized and gradually established, so as to make the most recommended parking spots for novice drivers in the future. It is worth noting that since the parking spot is a regional concept and not a fixed location, it is necessary to gradually establish the recommended parking area and range through data analysis and learning.
除了停車地點的建議,本發明實施例還能評估(易)違規地點。In addition to suggestions for parking locations, embodiments of the present invention can also evaluate (prone) violation locations.
圖7是依據本發明一實施例的違規地點決定的流程圖。請參照圖7,於步驟S710中,伺服器30的處理器36可統計違規事件的事件次數。Fig. 7 is a flow chart of determining a violation location according to an embodiment of the present invention. Referring to Fig. 7, in step S710, the
於一實施例中,感測資料包括定位紀錄,且違規事件的發生地點與定位紀錄的地點相距在統計範圍(例如,半徑10、50或100公尺)內。例如,違規事件是司機自行回報的或自業者自行提供的違規紀錄所得到的,透過通訊收發器33串接政府的公開資料庫(例如,記錄發生時間、地點、傷亡人數及經緯度)所取得的,或是透過車載裝置10的影像辨識或基於慣性感測資料的駕駛不良行為(例如,分心駕駛、疲勞駕駛、逆向行駛、闖紅燈、急煞、急轉彎、怠速或超速)判斷所取得的。統計時間可以是3天、一週或一個月。In one embodiment, the sensing data includes a positioning record, and the location of the violation event is within a statistical range (e.g., a radius of 10, 50, or 100 meters) from the location of the positioning record. For example, the violation event is obtained from a violation record reported by the driver himself or provided by the operator himself, obtained by connecting the
於步驟S720中,伺服器30的處理器36可判斷事件次數是否超過次數門檻值(例如,10、20或30次)。In step S720, the
於步驟S730中,針對這些超過次數門檻值的違規事件,反應於事件次數超過次數門檻值,伺服器30處理器36可分類這些違規事件對應的事件地點。In step S730, for the violation events that exceed the frequency threshold, in response to the event frequency exceeding the frequency threshold, the
例如,將半徑10或20公尺內的事件地點對應的違規事件分類到同一個事件群組。For example, the violation events corresponding to the event locations within a radius of 10 or 20 meters are classified into the same event group.
於步驟S740中,伺服器30的處理器36可依據事件地點定義違規地點。例如,某一個事件群組對應的區域範圍標記為(易)違規地點。而其他未超過次數門檻值的事件可定義成違規地點候選。In step S740, the
針對停車地點的提示,在一實施例中,伺服器30的處理器36可透過位置建議模型決定路線中的停留點對應的建議停車類別的第一停車地點。路線是由導航系統針對一個或更多個停留點的導航路徑或是經輸入操作編輯的路徑。停留點例如是送貨地點、景點或餐廳。Regarding the parking location prompt, in one embodiment, the
在一實施例中,伺服器30的處理器36可透過位置建議模型判斷停留點的推薦範圍(例如,半徑100、200或300公尺)內的街景影像是否為建議停車類別。若屬於建議停車類別,則處理器36將這街景影像對應的地點作為建議停車類別的第一停車地點。或者,這些第一停車地點已儲存在停車資料庫中,伺服器30的處理器36可自停車資料庫找尋推薦範圍內的第一停車地點。In one embodiment, the
在一實施例中,若有複數個第一停車地點,則伺服器30的處理器36可依據先前停車次數的多寡來排序這些第一停車地點。例如,停車次數越高的第一停車地點最優先推薦。In one embodiment, if there are a plurality of first parking spots, the
例如,圖8是依據本發明一實施例的停車地點建議的示意圖。請參照圖8,路線包括停留點P1~P5。伺服器30的處理器36可在以停留點P1為圓心的推薦範圍(例如,200公尺)內決定屬於推薦類別PT1的停車地點,在以停留點P2為圓心的推薦範圍(例如,200公尺)內決定屬於注意類別PT2的停車地點,並以停留點P4為圓心的推薦範圍(例如,200公尺)內決定屬於危險類別PT3的停車地點。不同停車位置類別可以不同視覺圖案、顏色、大小或文字呈現。For example, FIG. 8 is a schematic diagram of parking location suggestions according to an embodiment of the present invention. Please refer to Figure 8. The route includes stopping points P1~P5. The
於一實施例中,反應於車輛位於停留點的推薦範圍內,車載裝置10的處理器16可透過顯示器14或乘客的遠端裝置40提供這第一停車地點及其街景影像。In one embodiment, in response to the vehicle being within the recommended range of the parking spot, the
例如,圖9A是依據本發明一實施例的遠端裝置40的停車地點建議的示意圖。請參照圖9A,當車輛在距停留點200公尺內時,遠端裝置40可顯示與屬於推薦停車類別的停車地點P6的導航資訊I1(例如,預計抵達時間為1分鐘且距離160公尺)及街景影像SV1。For example, FIG. 9A is a schematic diagram of parking location suggestions of the
又例如,圖9B是依據本發明一實施例的遠端裝置40的停車地點建議的示意圖。請參照圖9B,車輛繼續移動,遠端裝置40可顯示屬於推薦停車類別的另一個停車地點P7的導航資訊I2(例如,預計抵達時間為3分鐘且距離320公尺)及街景影像SV2。As another example, FIG. 9B is a schematic diagram of parking location suggestions of the
除了停車位置類別的建議,遠端裝置40或車載裝置10也可提供違規地點的建議。例如,當定位裝置12所得到的位置資訊表示車輛移動至與違規地點相距警示範圍(例如,半徑50、100或300公尺)內,則遠端裝置40或車載裝置10提供這違規地點及其街景影像。In addition to the parking location category suggestions, the
在一實施例中,伺服器30的處理器36可透過位置建議模型或基於審核結果取得路線中的停留點的評估範圍(例如,100、200或300公尺)內的街景影像對應的停車位置類別,並自評估範圍內的街景影像中提供受決定為建議停車類別的第二停車地點。也就是說,伺服器30的處理器36可透過位置建議模型判斷停留點的評估範圍內的街景影像是否為建議停車類別。若屬於建議停車類別,則伺服器30的處理器36將這街景影像對應的地點作為建議停車類別的第二停車地點。這第二停車地點被儲存至停車資料庫,以供後續存取。In one embodiment, the
在一實施例中,車載裝置10的處理器16可透過顯示器14或乘客的遠端裝置40提供任務內容。In one embodiment, the
圖10A是依據本發明一實施例的遠端裝置的任務預覽的示意圖。請參照圖10A,以送貨為例,任務內容I3包含總共要跑幾趟,每趟有幾個配送點要配送,並顯示一天的天氣來提醒司機,路程是否因天氣影響而增減。FIG. 10A is a schematic diagram of a task preview of a remote device according to an embodiment of the present invention. Please refer to Figure 10A, taking delivery as an example. Task content I3 includes a total of several trips to be made, and several delivery points for each trip. The weather of the day is displayed to remind the driver whether the distance is increased or decreased due to weather effects.
圖10B是依據本發明一實施例的遠端裝置的任務預覽的示意圖。請參照圖10B,任務內容I4包括每一任務的配送細節(例如,收貨人、地址、車程及易違規事件提醒)。每一任務還搭配一鍵通話功能,以方便使用者預先詢問收貨人是否在家方便收貨。若收貨人不在,遠端裝置40透過接收使用者介面中的略過(skip)按鈕上的點擊操作,可跳過這單並自動重新規劃路線。FIG. 10B is a schematic diagram of a task preview of a remote device according to an embodiment of the present invention. Referring to FIG. 10B , the task content I4 includes the delivery details of each task (for example, consignee, address, driving distance, and easy violation event reminder). Each task is also equipped with a one-touch call function to facilitate users to ask the consignee in advance whether it is convenient to receive the goods at home. If the consignee is absent, the
此外,遠端裝置40還可如圖9A及圖9B事先顯示本次任務可供建議臨停候選地點,並顯示停車熱區地圖位置及街景影像。藉此,可方便司機透過地圖模式直接預覽路線,可直覺觀察配送點、易違規事件提醒圖示及停車熱區建議地點。In addition, the
此外,司機在配送過程中可使用車載裝置10所提供的功能。例如,導航配送路線、易違規事件提醒(語音及畫面)、停車熱區建議、配送細節查看(例如,收貨人、地址、路程、一鍵通話、略過任務)。配送過程中,停車地點或違規地點可透過語音提醒,但也可關閉語音提醒。語音提醒功能的切換可一併通知給管理端的遠端裝置40,以方便了解提醒狀態。In addition, the driver can use the functions provided by the vehicle-mounted
另一方面,為了實現節能減碳,幫助車隊管理者減少不必要的能源耗損所造成的成本問題,也落實環境保護的企業責任,需要進一步分析駕駛行為是否符合節能要求。On the other hand, in order to achieve energy conservation and carbon reduction, help fleet managers reduce cost problems caused by unnecessary energy consumption, and implement corporate responsibility for environmental protection, it is necessary to further analyze whether driving behavior meets energy conservation requirements.
圖11是依據本發明一實施例的駕駛行為的分析方法的流程圖。請參照圖11,步驟S111的說明可參酌圖4的步驟410,於此不再贅述。FIG11 is a flow chart of a method for analyzing driving behavior according to an embodiment of the present invention. Referring to FIG11 , the description of step S111 may refer to step 410 of FIG4 , which will not be described in detail here.
伺服器30的處理器36可依據一個或更多個節能因素決定感測資料的節能分數(步驟S112)。具體而言,節能因素是影響車輛的能源消耗的因素。The
在一實施例中,感測資料包括車輛的車速,節能因素包括定速巡航,且節能分數包括定速巡航的次分數。In one embodiment, the sensing data includes the vehicle speed, the energy saving factor includes cruise control, and the energy saving score includes a sub-score of the cruise control.
圖12是依據本發明一實施例的定速巡航分析的示意圖。請參照圖12,伺服器30的處理器36可統計旅程中的(實際)車速121與節能巡航速度122之間的第一累積差異。例如,以秒為單位,比對節能巡航速度122減去車速111的差值的絕對值,並累加每一秒的差值的絕對值。Figure 12 is a schematic diagram of cruise control analysis according to an embodiment of the present invention. Referring to FIG. 12 , the
於一實施例中,旅程可以是一天的總旅程或其他時間範圍內的旅程。車輛完全靜止時,不累計差值。節能巡航速度可能依據車輛的類型及/或道路而不同,並相關於節能模式下的行駛速度。In one embodiment, the trip may be the total trip of a day or trips within another time range. When the vehicle is completely stationary, no difference is accumulated. The eco-cruise speed may vary depending on the type of vehicle and/or road, and is related to the driving speed in eco-mode.
另一方面,伺服器30的處理器36可統計旅程中的(實際)車速121與道路速限123之間的第二累積差異。例如,以秒為單位,比對道路速限123減去車速111的差值(如圖所示的網底部分)的絕對值,並累加每一秒的差值的絕對值。車輛完全靜止時,不累計差值。On the other hand, the
接著,伺服器30的處理器36可依據第一累積差異及第二累積差異決定這定速巡航的次分數。當節能巡航速度122大於道路速限123時,伺服器30的處理器36可僅累計第一累積差異。當道路速限123大於節能巡航速度122時,伺服器30的處理器36可僅累計第二累積差異。Then, the
接著,伺服器30的處理器36將第一累積差異及第二累積差異加總。若加總值所占旅程的總時數的比例越低,則定速巡航的次分數越高。也就是,實際行駛的車速121接近節能巡航速度122或道路速限123的比例越高,因此節省越多能量。而若加總值所占旅程的總時數的比例越高,則定速巡航的次分數越低。也就是,實際行駛的車速121接近節能巡航速度122或道路速限123的比例越低,因此越耗能。Next, the
在一實施例中,感測資料包括車輛的煞車行為,節能因素包括滑行,且節能分數包括滑行的次分數。圖13是依據本發明一實施例的滑行分析的示意圖。In one embodiment, the sensing data includes the braking behavior of the vehicle, the energy saving factor includes coasting, and the energy saving score includes a sub-score of coasting. Figure 13 is a schematic diagram of sliding analysis according to an embodiment of the present invention.
請參照圖13,滑行的定義可以是,車輛在紅燈前停止線前50公尺或與前車距離50公尺(然距離不以此為限),車外影像中無法偵測前方有車輛,車輛是放開油門且車速大於零。處理器36可統計旅程中的滑行至一個或更多個停止點的煞車行為的煞車次數。例如,到達第一個停止點之前,煞車次數為3次。伺服器30的處理器36可依據煞車次數決定這旅程中的滑行的次分數。例如,旅程中所有煞車次數佔停止點的數目的煞車比例。若這煞車比例越高,則滑行的次分數越低,且越耗能。而若這煞車比例越低,則滑行的次分數越高,且節省越多能量。Please refer to Figure 13, the definition of coasting can be that the vehicle is 50 meters before the stop line before the red light or 50 meters away from the vehicle in front (but the distance is not limited to this), no vehicle can be detected in the image outside the vehicle, the vehicle has released the accelerator and the speed is greater than zero. The
在一實施例中,感測資料包括車輛的超速行為,節能因素包括超速,且節能分數包括超速的次分數。伺服器30的處理器36可將一秒內多筆的超速行為組合成一筆行為。若最大車速與速限的速差大於超速門檻值(例如,每小時5公里、10公里或15公里),則伺服器30的處理器36定義為超速行為。伺服器30的處理器36可依據超速行為的持續時間決定超速事件。若受定義為兩超速行為的間隔時間(即,持續時間)超過間隔門檻值(例如,5秒、10秒或20秒),則伺服器30的處理器36將這段持續時間的超速行為定義為超速事件。若速差沒有大於超速門檻值或持續時間未超過間隔門檻值,則伺服器30的處理器36繼續偵測後續的超速行為。In one embodiment, the sensing data includes speeding behavior of the vehicle, the energy saving factor includes speeding, and the energy saving score includes a sub-score of speeding. The
伺服器30的處理器36可統計旅程中的超速事件的超速次數,並依據超速次數決定超速的次分數。若超速次數越多(例如大於對應次數門檻值),則超速的次分數越低,且越耗能。若超速次數越低(例如小於對應次數門檻值),則超速的次分數越高,且節省越多能量。The
在一實施例中,感測資料包括車輛的車速及引擎轉速,節能因素包括怠速,且節能分數包括怠速的次分數。相似地,伺服器30的處理器36可將一秒內多筆的怠速行為組合成一筆行為。處理器36可依據車速及引擎轉速決定怠速行為。若統計的車速(例如,平均車速或車速中位數)為零但引擎轉速大於零的情況,則伺服器30的處理器36定義為怠速行為。若受定義為兩怠速行為的間隔時間(即,持續時間)超過累積門檻值(例如,10秒、20秒或1分鐘),則伺服器30的處理器36將這段持續時間的怠速行為定義為怠速事件。也就是,怠速事件是發生在車速為零但引擎轉速大於零的情況下。In one embodiment, the sensing data includes vehicle speed and engine speed, the energy saving factor includes idle speed, and the energy saving score includes a sub-score of idle speed. Similarly, the
伺服器30的處理器36可統計旅程中的怠速事件的累積怠速時間。當確定怠速事件時,伺服器30的處理器36持續統計這怠速事件的持續時間,以作為累積怠速時間。伺服器30的處理器36可依據累積怠速時間決定怠速的次分數。累積怠速時間例如是不超過3分鐘(依據法規決定)。若累積怠速時間越多(例如大於對應時間門檻值),則怠速的次分數越低,且越耗能。若累積怠速時間越低(例如小於對應時間門檻值),則怠速的次分數越高,且節省越多能量。The
在一實施例中,感測資料包括該車輛的加速度及車速,節能因素包括預期事件,且節能分數包括預期事件的次分數。伺服器30的處理器36可依據加速度及速度決定急煞事件。急煞事件是發生在朝車輛的行進方向上的加速度低於加速度下限且車速的變化期間大於變化上限的情況下。In one embodiment, the sensing data includes acceleration and speed of the vehicle, the energy saving factors include expected events, and the energy saving score includes sub-scores of expected events. The
例如,線性加速度計X軸(對應於行進方向)的最小值小於-0.28g(即,加速度下限,符號g為重力單位(gravity unit)),線性加速度計X軸在這段期間的平均累加量(以秒為單位)小於或等於-2.8秒,且車速在這段期間的平均變化期間(以秒為單為)大於或等於5.0秒(即,變化上限)。急煞事件的產生可能是前方車輛造成或發生事故,因此急煞事件的偵測可用於預期事件。For example, the minimum value of the linear accelerometer X axis (corresponding to the direction of travel) is less than -0.28g (i.e., the lower limit of acceleration, symbol g is the unit of gravity), the average accumulated amount of the linear accelerometer X axis during this period (in seconds) is less than or equal to -2.8 seconds, and the average change period of the vehicle speed during this period (in seconds) is greater than or equal to 5.0 seconds (i.e., the upper limit of change). The occurrence of sudden braking events may be caused by the vehicle in front or an accident, so the detection of sudden braking events can be used to predict events.
伺服器30的處理器36可將一秒內多筆的急煞行為組合成一筆行為。在統計的過程中,若平均線性加速度計X軸小於例如-0.17g且平均車速大於零,則伺服器30的處理器36可定義為急煞候選行為。The
若兩筆急煞候選行為的間隔時間(即,持續時間)超過間隔門檻值(例如,5秒、10秒或20秒),則伺服器30的處理器36將這段持續時間的急煞候選行為定義為急煞行為。反之,則伺服器30的處理器36繼續偵測後續的急煞候選行為。If the interval (i.e., duration) between two emergency candidate actions exceeds the interval threshold (for example, 5 seconds, 10 seconds or 20 seconds), the
在一些實施例中,伺服器30的處理器36還可透過辨識車外影像來判斷前方車流的速度及加速度,並據以作為急煞事件的評估。或者,處理器36還可透過辨識車外影像中與前車的距離,並對遠端裝置40或車載裝置10提示前車的距離,以減少急煞行為或其他異常煞車行為。In some embodiments, the
伺服器30的處理器36可統計旅程中的急煞事件的急煞次數,並依據急煞次數決定預期事件的分數。若急煞次數越多(例如大於對應次數門檻值),則預期事件的次分數越低,且越耗能。若急煞次數越少(例如小於對應次數門檻值),則預期事件的次分數越高,且節省越多能量。The
在一實施例中,感測資料包括車輛的引擎轉速,節能因素包括綠帶(green band),且節能分數包括綠帶的次分數。處理器36可統計旅程中的引擎轉速符合目標轉速的累積有效轉速時間(例如,每分鐘1400~1600轉)。目標轉速是依據車輛的車型及道路狀況所決定,並相關於節能模式下的引擎轉速。例如,下坡路段的目標轉速較低,但上坡路段的目標轉速較高。當引擎轉速在目標轉速的容許範圍(例如,每分鐘30~50轉)內時,伺服器30的處理器36可計時,並得出累積有效轉速時間。處理器36可依據累積有效轉速時間決定綠帶的次分數。若累積有效轉速時間所占旅程的總時間越多(例如大於對應時間門檻值),則預期事件的次分數越低,且越耗能。若累積有效轉速時間所占旅程的總時間越少(例如小於對應時間門檻值),則預期事件的次分數越高,且節省越多能量。In one embodiment, the sensing data includes the engine speed of the vehicle, the energy-saving factor includes the green band, and the energy-saving score includes the sub-score of the green band. The
在一實施例中,感測資料包括車輛的車內溫度,節能因素包括空調使用,且節能分數包括空調使用的次分數。伺服器30的處理器36可統計旅程中的車內溫度符合目標溫度的累積節能時間。這目標溫度是依據氣候所決定。In one embodiment, the sensing data includes the vehicle interior temperature, the energy saving factor includes the use of air conditioning, and the energy saving score includes the number of times the air conditioning is used. The
例如,夏天對應於溫度下限,且冬天對應於溫度上限。當車內溫度在目標溫度的容許範圍(例如,1度或3度)內時,伺服器30的處理器36可計時,並得出累積節能時間。For example, summer corresponds to the lower temperature limit, and winter corresponds to the upper temperature limit. When the temperature inside the vehicle is within the allowable range of the target temperature (for example, 1 degree or 3 degrees), the
在一實施例中,伺服器30的處理器36可依據累積節能時間決定空調使用的次分數。若累積節能時間所占旅程的總時間越多(例如大於對應時間門檻值),則空調使用的次分數越低,且越耗能。若累積節能時間所占旅程的總時間越少(例如小於對應時間門檻值),則空調使用的次分數越高,且節省越多能量。In one embodiment, the
例如,每一溫度和每一特定時間(例如:每一分鐘為一個單位),夏天車內溫度低於標準值範圍的情況可視為不良節能駕駛,冬天車內溫度高於標準值範圍的情況可視為不良節能駕駛。依據整趟行駛時間(即,旅程的總時間),每一單位在不良好駕駛範圍內的比例來計算次分數。For example, for each temperature and each specific time (e.g., one minute as one unit), the temperature inside the car is lower than the standard value range in summer and is considered as uneconomical driving, while the temperature inside the car is higher than the standard value range in winter. The score is calculated based on the proportion of each unit in the unhealthy driving range to the entire driving time (i.e., the total time of the journey).
表(1)是一範例說明多個節能因素的次分數。
表(1)
在一些實施例中,感測資料還可以是胎壓或定期保養通知。伺服器30的處理器36可依據胎壓過低(例如,小於標準的10%)或保險通知的偵測結果透過通訊收發器33通知遠端裝置40或車載裝置10。In some embodiments, the sensed data may also be tire pressure or regular maintenance notifications. The
在一實施例中,節能因素有多種。伺服器30的處理器36可對這些節能因素賦予權重,並將這些節能因素的次分數依據對應權重進行加權運算及/或正規化運算,以得出節能分數。In one embodiment, there are multiple energy saving factors. The
請參照圖11,伺服器30的處理器36依據節能分數產生駕駛行為報告(步驟S113)。具體而言,駕駛行為報告說明節能分數的優劣。伺服器30的處理器36可自多個節能分數(例如是針對不同車輛或司機)中選擇參考分數,並分別比較這些節能分數與參考分數,從而得知駕駛行為是否節能,進而作為節能駕駛的參考學習依據。Referring to FIG. 11 , the
在一實施例中,感測資料對應於路線中的多個路段,且這些路段是依據道路特性分類。例如,直線路段、轉彎路段、上坡路段、下坡路段、高速路段或非道路路段。伺服器30的處理器36可分別產生這些路段的節能分數,並分別比較這些路段的節能分數與對應的參考分數。駕駛行為報告包括這些路段的比較結果。藉此,針對各路段比對不同駕駛行為,可幫助駕駛員了解在相同路況條件下如何為最省油的駕駛方式,進而作為節能駕駛指標。In one embodiment, the sensing data corresponds to multiple sections in the route, and these sections are classified according to road characteristics. For example, a straight section, a turning section, an uphill section, a downhill section, a highway section, or a non-road section. The
在一實施例中,伺服器30的處理器36可依據駕駛行為報告決定駕駛狀態。例如,伺服器30的處理器36將節能分數與參考分數的分數差異分級,並由級數來評斷駕駛狀態。若級數越高,則駕駛狀態越好。若級數越低,則駕駛狀態越差。In one embodiment, the
伺服器30的處理器36可透過通訊收發器33對遠端裝置40或車載裝置10通知駕駛狀態符合通報條件的情況。通報條件相關於節能分數的排名。The

綜上所述,在本發明實施例的位置的評估方法、駕駛行為的分析方法及駕駛管理系統中,收集感測資料,自感測資料找出特徵值,結合審核,以作為演算法的訓練資料,從而可找出適合停車的推薦地點。物聯網裝置或者運輸載具上的感應器及影像擷取裝置可持續收集感測資料,且系統持續訓練所需推薦地點的演算法或更新資料庫。本發明實施例可提供介面給資料科學家或管理者對所收集感測資料進行修改、審核及標註,本發明實施例亦提供介面給開發人員進行演算法參數調整,以確保推薦地點合乎使用者對推薦地點的期望。本發明實施例亦提供一個評分機制,自動將駕駛行為依據路徑分段比對,找出具有最高節能分數的駕駛人的行駛行為並作為標準依據。路段的比較(benchmark)可作為評估駕駛行為的依據,並產出駕駛行為報告,進而用來作為駕駛訓練的參考依據。藉此,可改善新手司機不熟悉路況所造成效率低落的問題,協助提升行車安全,節省傳統司機帶人教育訓練、及因不良駕駛習慣造成能耗浪費所帶來的營運成本,且提升新手司機執行任務的效率。In summary, in the location evaluation method, driving behavior analysis method and driving management system of the embodiments of the present invention, sensing data is collected, feature values are found from the sensing data, and combined with the review to serve as training data for the algorithm, so as to find recommended locations suitable for parking. Sensors and image capture devices on IoT devices or transportation vehicles can continuously collect sensing data, and the system continuously trains the algorithm for the required recommended locations or updates the database. The embodiments of the present invention can provide an interface for data scientists or managers to modify, review and annotate the collected sensing data. The embodiments of the present invention also provide an interface for developers to adjust algorithm parameters to ensure that the recommended locations meet the user's expectations for the recommended locations. The embodiment of the present invention also provides a scoring mechanism, which automatically compares driving behaviors according to route segments, finds the driving behaviors of drivers with the highest energy-saving scores and uses them as the standard basis. The comparison of road segments (benchmark) can be used as a basis for evaluating driving behaviors, and a driving behavior report can be generated, which can be used as a reference for driving training. In this way, the problem of low efficiency caused by novice drivers' unfamiliarity with road conditions can be improved, helping to improve driving safety, saving the operating costs caused by traditional driver training and energy waste due to bad driving habits, and improving the efficiency of novice drivers in performing tasks.
