Description

SMART SAFETY SYSTEM FOR MOTOR VEHICLES

Technical Field

The invention relates to a smart safety system that can be used in different car rental modes based on days, minutes, hours, mileage and use, in the security of individuals' own vehicles, in the effective management and security of fleets, and in the creation of company and individual-specific car rental models.

The invention particularly relates to a smart safety system developed to prevent theft of motor vehicles and equipment belonging to these vehicles and to the smart safety method carried out by this system.

Prior Art

A new rental model called carsharing is rapidly becoming widespread in the world and constitutes the rental model of the near future. This system basically works in the form of parking the vehicle by leaving the keys in the vehicle, the renter coming to the vehicle and unlocking the vehicle through the mobile application and accessing the key, starting to use the vehicle, and when they finish their work, parking it where they want, ending their rent. The fact that the key is left inside the vehicle is almost an incentive for theft. Therefore, new security solutions are needed to rent vehicles in this model and assure that they are not stolen.

Some solutions are applied against theft in the prior art. Previous solutions are also tried to prevent the operation of vehicles by using analog technologies and relays. In this case, anyone who can break through the vehicle window can steal the vehicles by removing the safety systems on the vehicle in a few seconds. In addition, the physical condition of the vehicle is very difficult to understand, since all the necessary information cannot be obtained from the vehicles and is generally dependent on the customer's complaint (tire down, door open, battery dead, low on fuel, drives without seatbelt, need to use handbrake while driving, dangerous driving, etc.). In addition, there is no system that notifies or prevents this when the renters or malicious persons steal equipment such as tapes, tires, rims from the vehicles or parts from the engine.

For example, a malicious person can open the hood of the vehicle and steal any part from inside or someone who rents the vehicle can steal very expensive equipment from the vehicle. The worst is that this situation goes unnoticed.

In order to install the safety systems used in the prior art, a lot of the vehicle cables are cut and the cables of the security devices are connected instead. The installation of these security devices was both difficult and endangered the safety of the vehicle and the driver.

One of the most important disadvantages is that the vehicle cannot be safely stopped remotely if it is stolen after rental. The system tries to prevent theft by cutting fuel through a relay in conventional methods. In this case, the thief can easily deactivate this safety system by cancelling this relay quickly. The same applies to customers for whom payment cannot be collected. The customer continues to drive when the credit card limit has been exceeded, and the owner cannot or is not able to prevent this situation in many cases. For these reasons, it is a great necessity to stop the remote engine of a vehicle in a safe structure.

No patent application similar to the system subject to the invention has been found in the patent research. However, there are some patents on a similar technical field. One of them is the patent application numbered TR2018/13032. The said invention relates to a vehicle safety system that enables controlling the movement around a vehicle by means of sensors on the vehicle, taking an image of the vehicle surrounding and recording it in a storage unit, and creating a warning indicating that a movement took place around the vehicle; transmitting the recorded images to the electronic device of the vehicle owner.

The patent application TR2017/19935 relates to a vehicle safety system which determines whether a live being exists in the vehicle by controlling the underbody, surrounding, and inner part and upon determining a live being, sends a warning and/or notification.

Object of the Invention The advantages obtained with the system subject to the invention are described in detail in the following articles. i. Reservation-based safety system:

All kinds of information from the vehicle is used to increase the security of the vehicle thanks to the method subject to the invention. For example, when the doors of the vehicle are opened when there is no rental on the vehicle, the horn is automatically honked, the engine of the vehicle is rendered inoperable, and warnings are given with headlights and quads. While a normal auto alarm can only be activated when the doors are locked from the vehicle's control, in this system, the security precautions depend on whether the vehicle is in rent or not. This method can be used not only for rental vehicles but also for private vehicles. For example, you can put a vehicle that you will not use for a long time in a safe mode through a mobile application, etc., so that if your vehicle is attempted to be stolen, the thieves will not be able to start and steal your vehicle even if they disassemble the telemetry device. They will also move away from the vehicle thanks to the smart alarm system that is activated. ii. Vehicle owners can use systems with the features and structure mentioned in this method when needed, to open the door of their vehicles remotely, etc. It is easy to find the vehicle by managing the headlights and hom of a vehicle that you do not remember where you park through a mobile application, etc. iii. Vehicle manufacturers find it difficult to find the sold vehicles in the stock areas they park, as well as to find out which keys belong to which vehicle. A stock of 40,000 vehicles means 40,000 keys. The keys are left inside the vehicles and the doors are locked remotely in this system. While the telemetry device shows where the vehicle is in the stock area, it will be easier to locate the vehicle by remotely managing systems such as horns, headlights, etc. When you go to the side of the vehicle, the doors are opened through the system and the vehicle is easily found, and since the key related to the vehicle is kept in the system, its loss-wrong delivery is prevented. iv. Driver profiling and the development of pricing models according to this profiling can be provided thanks to the dozens of data read from the vehicles. v. It can be understood which type of vehicles can be rented more efficiently and according to the need in the region by making deductions from the door conditions and seat belt, such as the number of people travelling in the vehicle, the distance travelled, fuel consumption, the time spent in traffic, etc. thanks to the data collected from the vehicles. If there is no need, smaller vehicles can be rented according to need in the regions with parking problems in this way. This will increase customer satisfaction and reduce the costs of the renting operation. vi. Each rented car travels in every part of the city. Anonymous usage data collected from these vehicles (engine torque, accelerator pedal position, outside air temperature, engine load, door conditions and number of people carried thanks to seat belt, time of use, distance of use, etc.) are matched to the locations, and design and simulation support can be given to newly designed automotive technologies thanks to the data. For example, if these data are obtained when designing electric vehicles, the control units of electric vehicles are encoded according to the data and a longer range can be provided.

The inventive smart safety system (A) performs the methods described in detail above, as shown in Figure 1. Smart safety system (A) can be applied to all kinds of motor vehicles (1) of different types and brands. For this purpose, a telemetry device (2) is mounted to the socket in the lower region of the steering wheel to which the diagnostic devices are also connected and which is present in each vehicle. The telemetry device (2) is in constant communication with the vehicle's control unit (electronic brain) and comprises an electronic card (2.1) with embedded software that can collect different types of data. Canbus, J1708, RS485, K-line, Linbus analog 1/0, Digital 1/0 can be used as the communication protocol between the vehicle (1) and the telemetry device (2).

The telemetry device (2), which is in constant communication with the control unit of the vehicle (1), is also in mutual communication with a server (3) having a software suitable for the operation of the system. All kinds of data collected from the vehicle (1) with the telemetry device are sent to the server (3) with wireless data transfer methods (6) such as Bluetooth, Wifi, Lora, GSM, GPS. The smart device (4), which has a mobile application specially developed for the system, enables the transmission of the desired commands to the vehicle through the server (3). These commands can be all kinds of commands such as smart alarm/panic mode, engine blocking, engine stopping etc. against vehicle or vehicle equipment theft.

The functions performed with the smart safety system (A) subject to the invention are described in detail below. Engine Blocking Method: Carsharing structure, which is a new type of car rental system, is growing very rapidly all over the world and replacing the traditional rental method. However, the biggest problem is to ensure the security of the vehicles. Briefly, carsharing is leaving the vehicle key inside and waiting for the customer to rent the vehicle. A vehicle with a key in it is an open target for theft. The vehicle must not be started except for rental in order to prevent this situation. There is also a need for different solutions at different stages for other attacks.

Vehicle Engine Blocking Method: Almost every vehicle produced in the last 15 years is controlled by electronic control units. For example, the vehicle's engine is controlled by a control unit. These control units are produced in an architecture that will work in many make- models and vehicle types. For example, both the automatic version and the diesel version of a vehicle of the same brand and year have the same engine control unit, but this control unit is programmed according to the vehicle characteristics. If these settings are not suitable for the vehicle, it becomes impossible for the engine to start. Each vehicle has dozens of different settings in different control units. Some of these are settings that concern the security of the vehicle and allow the control unit to decide whether the vehicle will start or not. For example, when the control unit of a vehicle with automatic gear is coded according to the manual gear option, the vehicle cannot be started even with its own key. This setting is permanent. The vehicle will not start unless it is encoded again according to the automatic gear selection. Many control units, such as this example, have similar settings. The telemetry device (2) on the vehicle applies this code to the vehicle and makes it inoperable at the end of the rental period of the vehicle. After this coding, even if the thief breaks the window of the vehicle and dismantles the devices, they will no longer be able to start the vehicle with their own key, and the theft, which is the biggest problem, will be prevented. One or more encodings can be applied within the same structure to increase security.

The second structure subject to the method is the manipulation of the information circulating in the vehicle network so that this coding does not recognize certain equipment of the vehicle. An example is sending a signal to the vehicle in such a way that the telemetry device manages the immobilizer commands so that the vehicle does not recognize its own key. The vehicle will take itself into safe mode and become inoperable in this way. This method is done thanks to digital data (canbus-kline-jl708-flexray etc.) sent using the vehicle's own network. There is no need to cut wires or tamper with the vehicle's wiring. Security Engine Stop: It is very important to stop the vehicle remotely if it is stolen after rental. The thief will not be able to move the vehicle in this way. The same applies to customers for whom payment cannot be collected. The customer continues to drive a rental car when the credit card limit has been exceeded, and the owner is not able or able to prevent this situation in many cases.

The control units of the vehicles communicate with each other over one or more networks. A data required by a control unit is sent by another control unit connected to the same network. For example, the vehicle key or start button is connected to the vehicle body control unit and this information is provided to the engine brain by the body brain to start or stop the engine. When the vehicle needs to be stopped remotely (theft, security breach, act of terrorism, etc.), the equipment in the vehicle constantly checks the vehicle speed it is reading. When the vehicle speed drops below a preset speed (for example, when the vehicle slows down to a speed of 5 km or less), it begins to send the necessary manipulated commands (for example, even if the ignition is on, ignition off information instead of this message) for the vehicle to stop to the engine. These commands are continuously sent until the engine of the vehicle stops. Similar messages can be singular or multiple, i.e., one or more messages that affect the operation of the vehicle can be used at the same time in this method. This method can also be used in combination with the smart panic mode described below.

Smart Panic/Alarm Mode: This method is basically a reservation-based alarm system and remote panic mode that is created by managing the vehicle's own equipment or additional accessories such as the siren that are connected externally. The purpose of this method is to ensure that the vehicle is secure, and alerts the environment like a vehicle alarm in case of a security breach.

The method operates in such a way that after the rental of the vehicle is over, the telemetry device continuously reads the data from the vehicle equipment such as status of the doors, central locking, hood-luggage status, ignition status, condition of the windows, or from additional sensors such as the impact sensor to be added to the system and in case of a security violation (opening of the door, opening of the hood, etc.), the vehicle honks with the commands given by its own control units, turns the flashers on, turns on and off the high and low beams, locks the doors, blocks the engine, and stops the engine if it is running. The mobile application or server software notifies this situation to the telemetry device with a command at the end of the rental period. Receiving this command, the telemetry device activates the smart alarm system method and sends the pre-recorded command sets to the vehicle in case of opening the door etc., as mentioned above, and allows the vehicle to react in the form of horn etc., as mentioned above. The mobile application or server software notifies this situation to the telemetry device with a command when the rental period starts. Receiving this command, the telemetry device turns off the alarm mode and does not react if the vehicle doors are opened, etc. Activating this feature at any time is called smart panic mode. Smart panic mode can be safely implemented even when the vehicle is in motion. The server or mobile application sends the panic mode command to the telemetry device at the time of a theft. Receiving this command, the telemetry device causes the vehicle to activate the alarm mode features such as honking to the control units in the vehicle using its own network, alerts the surrounding area and provides that the thief moves away from the vehicle. It can be used together with the remote engine stop method, or separately.
