Description

Modular safe driving assistant Technical Field

The invention relates to a safe driving assistant in a modular structure, which can be used in all road vehicles, with a lane departure warning system and a follow-up distance warning system, in which different systems can be integrated according to vehicle characteristics and user demands.

Known Status of Technique

Vehicle manufacturers; offer FDWS (Following Distance Warning System), LDWS (Lane Departure Warning System), TPMS (Tire Pressure Monitoring System), TDGS (Tonnage Over Warning), Damper Open Warning, Rear View System systems to their customers standard or optional in new production vehicles. However, these products can not be applied to different brands, models or even old production vehicles of the same brand. Moreover, these products are not included within the markets to which customers have access.

In the markets accessible to the consumers, the products which contain some features of the product under the scope of the invention such as LDWS, FDWS, TPMS can be found separately as modular. These products are not integrated as intermediaries but are used as external products. Besides, there is no product that contains all of these together and can be shaped according to consumer demands (data transfer, reporting, conformity to vehicle specifications, etc.). Separate use of each product (such as use of different displays for each visual stimulus) makes the product useless and causes information confusion. Also, many of them cannot transfer data to Fleet Management, and those who can transfer data cannot provide a wide range.

In the summary of the TR2010 / 01689 numbered utility model application for vehicle follow-up distance the following expressions are included: "This invention relates to a follow-up distance control system (1 ) which is applied to motor vehicles to reduce traffic accidents by drawing attention of drivers in motion on the road. In the system, there is a warning signal (4) which is placed on an area of the vehicle (2) that other drivers can see. The warning signal (4) draws the attention of other drivers by flashing different types and colors at different speed limits of the vehicle (2)". However, there is no electronic component in this system which is based on visual control and which requires attention of the driver. This system which is based on drawing attention raises only the attention level of the driver. It does not have any other control and warning mechanism except the attention of the driver.

As a result, due to the aforementioned negative aspects and inadequacy of existing solutions, an improvement in the technical field has been required.

Purpose of the Invention

The invention is based on inspiration from the current situation and aims to solve the aforementioned negative aspects.

Main purpose of the invention is to provide a driver assistant system for safe driving in a modular construction to which different systems can be integrated to meet user requirements and which can be used in all road vehicles, along with the lane departure warning system and follow-up warning systems. Thus, the aim is to prevent traffic accidents based on driver faults at the maximum level. In addition, it provides the ability to transfer driver's driving performance, vehicle status and malfunction status information to the fleet in real time. The invention is a safe driving assistant developed to be used in all vehicles, especially in commercial vehicles. In this respect, unlike its counterparts, it can be applied to all vehicles independent of their brands and models .The safe driving assistant under the scope of the invention which mainly includes basically Lane Departure Warning System and Follow up Distance Warning System also contains many systems according to vehicle specifications or user requirements. These are software and hardware products; such as Fuel Saving System, Tonnage Over Warning, Damper Open Warning and Rear View System, Tire Pressure Warning System, Vehicle Follow up System, Access to CANBUS data, front and rear image recording, data transfer and reporting to fleet. These systems are offered either as standard or optional according to vehicle specifications or fleet management requirements. Thus, the consumer has a product range that is modular and multifunctional and that can be shaped according to demands and requirements. In addition, new features (fire warning system, etc.) can be added to the product range as a result of the development works and these newly added features can be integrated into products that have been assembled in line with customer requirements.

Besides, remote monitoring of vehicle and possible vehicle malfunctions and tire pressures, remote monitoring and reporting driving performance of the drivers are also aimed. In addition to providing data to fleet managers to minimize fuel consumption due to tire pressure and driving performance of the driver, contribution to decrease tire pressure based vehicle accidents and fuel consumption are also provided.

Lane Departure Warning System (LDWS): In the safe driving assistant, a road view is received with the aid of a camera placed in the front area of the vehicle and the received image is processed and lanes are found. Two levels of warning information are produced when the vehicle is in violation of the lane and by using this information; at Level 1 violation (20 % lane violation), the driver is factually warned by a vibration motor placed in the driver's seat and is also warned by a visual notification on the system screen. In case of Level 2 violation (40 % lane violation), the driver is visually alerted with a warning led and is audial alerted with the help of buzzer in addition to Level 1 warnings.

Following Distance Warning System (FDWS): The radar sensor located in the upper area of the vehicle's license plate in the safe driving assistant determines the distance to the vehicle driving in front and the relative speed between two vehicles. When the obtained data is processed, if danger of collision occurs then a two-stage warning information is generated and by using this produced information, in case of Level 1 violation, the driver is warned visually from the system screen and factually by vibration motor placed in the driver's seat. In case of level 2 violation, as the driver does not intervene to prevent the collision and so the crash is certain, then in addition to the same aforementioned warnings, the retarder brake is actuated in 4 stages and if the safe distance is reached, the warnings and retarder brake are automatically deactivated. However, if the system triggers the retarding brake and then the driver intervenes (such as speed up, signaling, etc.), the system stops braking and other warnings continue to be given until the safe driving distance is reached. In addition to the information received from the retarder button socket, the wiper socket, the temperature sensor, the system is working to give only audiovisual and tactile warnings on unfavorable road conditions (rain / snow, freeze and driver request) without interfering with the retarder brake.

Fuel Saving System (Over Speed, Instantaneous Braking, Instantaneous Acceleration, Idling Time, Over Revolutions / HAARD): Vehicle speed and revolution data are transferred to the system and this data is processed by the program to produce Over Speed, Over Revolution, Instant Acceleration, Sudden Braking and Idle status information and both the driver are warned and this information is sent to the fleet center to report driver performances.

Tire Pressure Warning System (TPMS): The pressure sensors are installed on the vehicle tires and the obtained data is transmitted to the system screen via the system and the driver is warned about inappropriate pressure values. It is aimed to prevent possible accidents due to low / high tire pressures. It is also possible to avoid excessive fuel consumption due to low tire pressure.

Tonnage Over Warning, Damper Open Warning and Rear Viewing System (TDGS): The necessary sensors and camera are added to the system and the audible, visual and tactile warnings are produced.

The features that distinguish the safe driving assistant from the similar ones are as follows:

• Decrease in accidents due to driver faults and decrease in fuel consumption,

• Being modular (applicable to all motor vehicles)

• Integrated with the Vehicle (all warnings can be reached from a single screen, audible and tactile communication sources can perform different functions together; in addition to these advantages, in vehicles with retarder brakes, if collision is unavoidable, retarder brakes can be used to prevent / mitigate collision, vehicles can reach the data in CANBUS line, etc.),

• It can be shaped according to user demands,

• To allow reporting of user faults and vehicle status (position, fuel data, vehicle malfunctions, etc.)

• Development of special versions for vehicle manufacturers that do not have adequate infrastructure (Warning systems in the system can be either used separately or used integrated with the hardware products that the vehicle have. For example, as a result of integration of the Vehicle Track Assistance and Lane Departure Warning System, lane violation warning for moving vehicles and keeping the vehicle within the lane by automatic control shall be possible or as a result of integration of Adaptive Cruise control systems and Distance Tracking and Warning System, speed of the vehicle shall be automatically reduced in case collision is unavoidable.)

The structural and characteristic features and all advantages of the invention will be more clearly understood by the following figures and by detailed description which are made by referring to these figures, therefore the evaluation should be done considering these figures and detailed explanations.

• The CANBUS module (25) that transfers the vehicle's CAN data to the image processing board (1 ).

Lane Departure Warning System (LDWS)

The road image received by the camera (5) placed on the vehicle front panel is transmitted to the image processing board (1 ). By processing the road image with the image processing card (1 ), the lane boundaries in the region where the vehicle is located and the location of the vehicle within these boundaries are determined. Based on the center point of both (left-right) lanes and center point of the vehicle, the center of the vehicle is compared with the center of the lane, and the distance from the center of the lane and the center of the vehicle is determined as a percentage. In the event that the vehicle goes another road outside its own lane due to the driver's sleeping or driver's lack of attention is warned visually by an optical warning lamp (1 1 ) which is located on the front panel of the vehicle, audible by the buzzers (10) which are preferably located on both sides of the front panel and factually by the vibration motor (9) connected under the driver's seat (seat vibration).

The image processing board (1 ) transfers the lane violation information and the violation video to the system control board (2), and the system control board (2) triggers the above-mentioned elements to be warned. The system control card (2) also broadcasts warning information on the touch screen (6) together with the corresponding visual. At the same time, the image processing board (1 ) also detects lane-based improper passing, driver errors are recorded and these records are sent to the company's data processing center.

The image processing board (1 ) adjusts the lane width adaptively in the different lane widths by specifying the lane width from the image of the camera (5). In the direction of customer requests LDWS also records the road images by adding image recording feature and can be examined if necessary. Said images are recorded by transferring from the image processing card (1 ) to the memory unit (8). In case of level 1 lane violation: visual display with touch screen (6), tactile warning with vibration motor (9).

In case of level 2 lane violation: Visual warning with touch screen (6) and warning lamp (1 1 ), and tactile warning by vibration motor (9) and audible warning by buzzer (10).

Following Distance Warning System (FDWS)

The distance sensor (19) located in the vehicle front bumper detects vehicles in the same lane and in front of the vehicle and communicates to its control unit (ECU / Electronic Control Unit) located in the containment box. The ECU generates three levels of violation information in the event of an unsafe following distance, depending on the speed of the vehicle. (Table 1 )

Figure imgf000012_0001

Table 1 The first and second level warnings generated by the ECU by data received from the distance sensor (19) are based on the time period information obtained by dividing the distance between the two vehicles by the speed of the following vehicle. The third level warning is based on the time period information (collision time) obtained by dividing the distance between the two vehicles by the speed difference between the two vehicles (relative speed).

This warning information which is obtained by means of the distance sensor (19) and ECU is used by being transferred to the system control board (2). On the system control board (2), the level 1 warning received from ECU is used as is, while the level 2 and level 3 warnings are combined and are used as a level 2 warning because at different speeds and relative speeds of vehicles, the third level warning can occur without any other warnings occur. FDWS measures the safe follow-up distance with regard to follow-up violations caused by the driver's lack of attention or driver's sleeping and alerts the driver as visually, audible and factually (seat vibration) during follow-up violations. At the same time, the system control card (2) automatically activates the vehicle's retarder brake in case of continued distance violation and danger of collision.

In addition, in response to information received from the retarder button socket (27), the wiper socket (28) and the temperature sensor (18), the system will only provide audiovisual and tactile warnings in unfavorable road conditions (such as rain / snow, freeze and driver request) without interfering with the retarder brake . The retarder brake is connected to the system via the retarder brake socket (26). With the system control card (2), illegal follow-up errors are detected, driver mistakes are recorded, and these records are sent to the control unit and / or the data processing center via the GPS module (7) via the image processing card (1 ).

Level 1 distance violation: Visual warning is given by the touch screen (6), tactile warning is given by vibration motor (9).

Level 2 distance violation: Visual warning is given by the touch screen (6) and the warning lamp (1 1 ), tactile warning is given by vibration motor (9) and audial warning is given by the buzzers (10). Also a retarder brake is introduced.

FDWS is designed such that it will give warning about adverse weather conditions (rain, icing, etc.) but not to interfere with the retarder brake. A temperature sensor (18) has been added to the FDWS for this purpose and the signal mentioning that wipers are working has also been used.

Fuel Saving System (HAARD)

The speed information from the car tachometer and the speed information from the speed sensor are sent to the system control board (2) and these information is processed here and during the use of the vehicle over speed, over-revolution, sudden acceleration, sudden braking and idle state information are produced.

HAARD allows to determine the driving performance of the driver and transfer these information to the fleet management. For this, the fuel saving system grades the drivers according to their driving performances and provides data so that necessary measures can be taken for fleet management.

HAARD considers the criteria of Speed Limit Exceeding, Sudden Braking, Sudden Acceleration, Idling Time and Speed Limit Exceedance in rating driver performance for fuel saving.

Tire Pressure Warning System (TPMS)

The tire pressure data obtained by the pressure sensors 20 placed in the vehicle tires are evaluated in the receiver 22 which is sent by the repeater 21 and the obtained data is transferred to the image processing board 1 to generate necessary warning information.

The TPMS alerts the driver by alarming the touch screen (6) in case of pressure loss in one or more tires. The tire air pressure is important for safe driving in terms of road handling and braking. Thus, TPMS helps to reduce tire-induced accident rates. In addition, keeping the tire air pressure at suitable values is also important for fuel consumption, tire life, customer satisfaction. In other words, TPMS is also an important system in terms of economic benefit.

Tonnage Over Warning, Damper Open Warning and Rear View System (TDGS)

TDGS warns that trucks and long-trucks exceed the maximum load limits and the vehicle is moving while the damper is lifted in the dump trucks audible with the buzzer (10) and visually with warning lamp (12) and touch screen (6). The tonnage sensor (24), damper switch (23) and back view camera (5) required for this are installed to the vehicle and the necessary data is reached. Furthermore, in the vehicle's reverse driving position, the image obtained by the camera (5) is reflected on the touch screen (6), thereby providing back support to the driver. Thus, it is aimed to prevent the accidents that may occur due to reasons such as overloading of vehicles, running in damped condition and insufficient visibility.

Save Box

With the camera (5) located in the safe driving assistant and other image recording devices which can be added on the vehicle in the desired situation, images around the vehicle can be obtained. These images to be held in the memory unit (8) can be transferred to a remote control unit, fleet management system or computer in desired situations. With the GSM module (7), the violation information will also be transferred to the mentioned units online. The image processing board (1 ) and the system control board (2) are electronic circuit boards and are the brains and control circuits of the safety vision system. These cards are placed in a box inside the vehicle and are connected to other equipment, preferably by means of cables. The hardware elements outside these circuit boards are connected to various suitable locations of the vehicle. The connections to the image processing board (1 ) and the system control board (2) are made with input and output sockets. The modular structure of the invention is also realized by the fact that different systems can be connected to the circuits via a simple socket connection. The data is sent by the image processing card (1 ) and the system control cards (2) to the control units / fleet management / remote computer. Through interfaces, the authorities can observe the data reported and evaluated.

One of the most important features of the safe driving assistant is the ability to reach and report on driver-related faults and vehicle conditions and failures. The fleet managers are provided with data on the arrangement of the fleet maintenance and repair schedule, early detection of unplanned maintenance and repairs (failure not grow /not to break down on the road), tracking / reporting of driver performances and fuel saving. If this feature is actively used, it can also be used as a fleet management assistant. Some of the violation information determined by the systems is determined by the system control card 2 and some by the image processing card 1 in the direction of the data coming to them. Violation information that are detected by the and that are to be sent to the hardware units Vibration motor (9), warning lamps (1 1 ), retarder brake etc. are transferred to the system control board (2). However, violation information that are determined by the system control board (2) from the speed information, revolution information, etc. that comes directly to itself are transferred to the image processing card (1 ) in order to give visual warning to the driver.
