FIELD OF THE INVENTION

The present invention is in the field of cars and vehicles and specifically related to steering wheel with car anti-theft monitoring system. Also, it is shows how to connect the car anti-theft system with the car steering wheel, which has the ability to adjust the size.

BACKGROUND OF THE INVENTION

Steering wheel in cars allows them by changing the angle of the front wheels of the car, it changes the direction of the car towards the front wheels. Although Steering wheel in terms of dimensions may not be suitable for the driver’s physical size, so the driver gets tired while driving. Furthermore, after parking the car, the driver may want to do something other than driving. In which case, there is little space to perform the desired activity because of the Steering wheel existence. So, change the steering wheel to suit the situation required by the driver in driving or parking mode is necessary. In cars with auto driver feature are better the steering wheel occupy the least space, so that the driver can have more space for doing other their desired activities. Furthermore, a size-adjustable steering wheel for multi-purpose vehicles like cars that used both as race cars and as city cars is needed.

Ensuring car security and preventing it from being stolen is one of the needs of the automotive industry. Manual steering wheel lock is another current problem. Drivers must install it after park the car and unlock it before moving. Locks and unlock steering usually used in order to further ensure that the car is not stolen. This activity is time-consuming, but car security is most important concern of car owners. Drivers can apply automatic steering lock system in intelligent retractable steering wheel in order to avoid wasting time and not using an additional device like manual steering lock. The present Steering wheel in addition to the advantage of being retractable, has an automatic lock feature that can be installed in any car without the need for factory changes.

Car safety has always been one of the most important issues for car owners. Using a smart steering wheel and connecting it to the anti-theft system can be one of the solutions to create more security in the car. After the driver sits in the car, a fingerprint sensor can be used for authentication, then the steering wheel which has already been resized according to the driver's want, is opened and ready for usage.

DETAILED DESCRIPTION OF THE INVENTION

Smart steering wheel has internal secondary lock and ability to fold or open manually as much as driver's want. Designed in such a way that the first time a new user enters the car cabin, finger print and desired size of steering wheel saved in its database. When the user leaves the car, the steering wheel is automatically retracted and its secondary lock is activated. By activating the secondary lock, it becomes impossible to move the steering wheel. There is no need to reset the steering wheel during subsequent entering. The steering wheel returns to the preset size of the driver only after identifying the driver's fingerprint. Steering wheel has three formats: circle, Semicircle, and air craft steering wheel format. Each of them can be changed based on the driver’s want. The monitoring system is responsible for protecting the car after locking the car. If it senses movement, turns on the monitor camera and microphone inside the car cabin and turns the camera towards the movement sensed, and starts filming or taking photos. These pictures and films saved at SD card and pictures send through email to driver. Also, it turns off fuel system and car electricity and locked doors. Then sends an alarm to car owner through SMS or mobile application. If the driver does not respond, it sends a text message to the nearest police station. Car monitoring system has mobile application that provides for drivers, observe the location of their cars through camera and microphone inside the car cabin and turn the camera around. View the photo taken from the car cabin in his/her email. Also, drivers with this application, can open and close the car door, turn on and off the car, connect or disconnect fuel system and car electricity. All of these features can be done by sending encrypted SMS, too. The user can also connect the gasoline valve of the car automatically and without pressing a key by having the remote control that she/he has with her/him, open doors and unlock steering wheel. Then change the steering wheel from fold to open. Also, user can turn off the car as he/she moves away, turn off the gasoline valve, close the car doors and fold and lock steering wheel and finally activate the protection and monitoring status of the system.

Smart steering wheel in has three formats: circle, Semicircle ( ), and air craft steering ( ) wheel format. This steering wheel generally consists of two main parts include electronic part and mechanical part. The mechanical part consists of three main parts. The first part is the opening mechanism that is responsible for opening and folding the steering wheel and opening Pulley Expanding Mechanism(507movements-numder224) is used in its mechanical structure. Figures 4 and 5 show steering wheel without cover.in steering wheels without cover in fold position and in shows open position with no gears to better show how the steering wheel is assembled on a steering wheel hub adapter.

The steering retraction mechanism shown in has been optimized with changes to the retractable pulley mechanism and the shutter camera. One of the advantages of this method is that the person who uses the steering has the same feeling of using the old steering that were circular or similar to a circle. Open the steering wheel is done by rotating the worm gear motor (no. 41) and moving in the direction of opening the small gear (no. 42) and causes the larger gears to rotate ( , no. 43). The pins that are in their paths with large gear rotation are made to move. Because these pins are connected to the steering handle (no. 44), the steering handle go out of their way and lead to form a complete steering wheel (no. 45). Of course, the pin and slider mechanism are used to connect the steering wheel handles to each other, in order to be uniform, the steering wheel. Number 44 shows connections that connect steering wheel handles to each other. For steering wheel fold, the worm gear motor must be turned vice versa and cause the steering wheel to retract. According to the above mentions and view the steering wheel format that is better seen in , this steering wheel consists of 5 steering handles that each of them has the ability to move back and forth in its slider path (No. 53). In order to convert steering wheel to circle, Semicircle, and air craft steering wheel formats, It is enough to reduce the number of these handles (number 45) when assembling the steering wheel. ( and 3)

Two micro switches are used to control the range of motion at the beginning and end of the linear path of the steering wheel slider. Using the micro switches, determine the complete closing and the full opening of the steering wheel through the signal received by the microcontroller through the micro switches.

As you see in , No. 41, this steering wheel by worm gear motor performed opening and closing. shows the time when the steering wheel is closed and shows the steering wheel when it is fully open. Worm gear motor in steering wheel allows to user wherever stops the engine, she/he can use the steering wheel to change the direction of the front wheels, so this rotation causing no change in size of the steering wheel.

The second part is steering wheel holder. This section only refers to how the car steering wheel is assembled on the steering columns and shafts. In general, the main mechanism of this steering wheel is implemented on the steering wheel hub adapter steering wheel. shows how to place it in the steering wheel. , number 52, shows the shape of a steering wheel hub adapter. Steering wheel hub adapter allows the retractable steering wheel system to run on all available steering wheel without the need for a platform.

The third part is secondary lock. As shown in Figures 7, 8 and 9, the retractable smart steering wheel includes an automatic steering wheel lock that when the steering wheel is fold, the steering lock motor operates on the command of its microcontroller and causes torque by rotating the gear (No. 71) attached to it. This torque makes a linear gear (No. 72) brings down. The second micro switch in this situation operated and causes the motor to shut down and eventually locks the steering wheel. and , shows how the process described above occurs. Once the steering wheel is locked, the steering wheel will no longer be able to open or even rotate to either side. This is due to the presence of the lock ring, which is visible with the number 73 in all three figures 7 to 9. The opposite the algorithm happens when the lock is opened. By commands from the microcontroller, the steering wheel lock motor causes rotate the gears attached to it and finally raises the linear gear. The linear gear receives the cut-off command from the microcontroller after hitting the first micro-switch, so the steering wheel is unlocked and ready to be unlocked by a Worm gear motor. Finally, for the user to use the steering wheel, it is necessary to place a suitable cover on it, which can be seen in on the left. The right side of shows view of the steering wheel in full circle mode. In order to place the appropriate volume on the steering wheel handle (45), the steering wheel cover is used, which is specified in with number 13.

Its open view can be seen in with the number 13. In order to better open and prevent the driver's hand from colliding with the opening mechanism in the joints of the steering wheel handle (No. 44), a flexible and at the same time hard part has been used as a cover and handle, which can be clearly identified by No. 11. This part allows connections of steering wheel handles move easily internally when the steering wheel is open or closed without interfering with the moving mechanism or hitting the driver's hand. This steering wheel in number 12 provides a suitable space for connecting the airbag on itself, which airbag installed on it.

Electronic part of smart steering wheel consists of 5 sections. First includes microcontroller and control board. Second is monitoring section that includes PIR sensors, camera, microphone and SDRAM. Third is transmitter and receivers that include GPS module, GPRS module Wi-Fi module and remote control. The fourth part is the user interface, which includes software. The fifth section is the power supply section, including the power supply section of the microcontroller and the power supply section of its other communication modules.

First section that includes microcontroller and control board is the main section of electronic part of smart steering wheel. This section is actually the core of the smart steering wheel. As a microcontroller, it is responsible for receiving information from sensors and micro-switches and sending the required commands to various peripheral units such as motor, GPS module, GPRS module, camera, microphone, etc. Here, the Arduino microcontroller MEGA2560 is used as the controller and master thinker of the smart steering wheel system, which together with the control board, which can be seen in , form the first part. The designed control board is responsible for connecting the micro-switches to the microcontroller and controlling the power of the gasoline valve, car power, car doors and remote car starter, which receives these commands through the MEGA2560 microcontroller. As shown in , the PMC4996X MOSFET IC and its driver circuit were used to control the devices. This IC basically acts as a switch that receives its commands from the MEGA2560 controller.

Due to the high Carry electric current when starting the car, according to , three parallel ICs have been used to supply the current required for this purpose. The corresponding pins in the microcontroller in order to communicate with the above-mentioned sides are as follows. Pin 4 microcontroller is intended for communication with car door power, and Pin 5 microcontroller is for connection to car gasoline valve power. The 24microcontroller pin is intended for communication with the car starter. An idler diode with the number IN5822 is placed in the path of these switches for protect the reverse current from the PMC4996X MOSFET IC. As mentioned in the mechanics section, in order to open the steering wheel, first it is necessary the worm gear motor number 41 start to move.

This done by using the L298 motor driver. For manual adjustment of the steering wheel, used a manual switch connected to the pin30 microcontrollers. Simply hold down this key for three seconds to enter the command settings of steering wheel, while the settings LED starts flashing. This LED connected to pin 33. You can open the steering by pressing the key that is connected to the pin 31 microcontroller after finishing. Then by pressing the key that is connected to the pin 32 microcontroller, can fold steering wheel as much as you want. Desired size can be saved by pressing manual adjustment key on pin 30 microcontroller for three seconds Until the LED flashes and the applied settings are saved. Meanwhile, the amount of opening or closing is measured by an internal timer microcontroller and to reopen as desired size customizes it for the user. This part can be replaced with an encoder for more accurate calculation so that the steering wheel returns exactly as much as the user needs on the next entry into the car.

This customization performed by fingerprint sensor for users. So, it is necessary to take the user's fingerprint as a personalization agent before entering the car and store it in the memory database with the username. When reusing the car, compare the fingerprint with the current user's fingerprint and if it is correct, car will be available to that user. The steering motor is connected to the L298 driver. IN1 and IN2 pins of this driver respectively connected to the pin 6 and 7 of microcontroller. In order to direct steering wheel, turn left or right, it is enough to set these pins and reset them or vice versa. Fingerprint sensor serially communicates with the microcontroller and Rx and Tx pins respectively connected to the pin Tx2 and Rx2 of microcontroller.

When adjusting the steering wheel, as stated in the mechanical description section, in order to determine the range of motion, two micro-switches are used, which are specified in as SW_1-1and SW_1-2. SW_1-1is connected to pin 10 of the microcontroller and SW_1-2to pin 11. As explained in the mechanical section about the secondary lock, in order to close the lock, it is necessary to move the secondary lock motor, which also needs to be powered by the motor driver with number L298.

This motor driver which operates with a voltage of 12 volts and is responsible for starting both the worm gear motor and the secondary lock motor. As mentioned before worm gear motor used to launch the smart steering wheel and lock motor used to launch the secondary lock. When the secondary lock motor moves, it moves the gear that is connected to the motor ( - number 71), which causes the linear gear No. 72 to move. The linear gear that acts as a lock comes down. When the linear gear reaches the end of its movement, the steering wheel is locked, which is notified to the microcontroller via the SW_2-2micro-switch shown in . The microcontroller like the steering wheel when locked, through the two micro switches SW_2-2and SW_2-1, which indicate the end and beginning range of the lock, notifies when the secondary lock is closed or open. Switches SW_2-2and SW_2-1are connected to

pins

12 and 13 of the microcontroller, respectively.

The secondary motor is connected to the L298 driver. The IN3 and IN4 pins of this driver are connected to pins 8 and 9 of the microcontroller, respectively. It is enough to direct steering wheel turn left or right, these pins set and reset them or vice versa. It should be noted that in order to rotate the camera, two DC servo motors have been used for this purpose. Both motor s use of one driver motor with L298 for moving. Monitoring section that includes PIR sensor, camera, microphone and RAM to store data on SD Card. There are two PIR sensors that are connected to the microcontroller via pins 21 and 22 and are located on either side of the car. Whenever they feel a movement, the car security algorithm is activated.

This section includes turning off the gas valve, locking the car doors, notifying the driver via the WIFI system, sending the car situation to the driver via GPS, activating the microphone and camera inside the car and sending a warning message to the user via SMS. It should be noted that each of the PIR sensors that are activated earlier, the camera turns towards it and starts filming and taking photos (at the interval specified by the user). It stores this data in its RAM and sends photos taken to the user's email. The camera module with model VC0706 is connected to the pins Rx1, Tx1 of the microcontroller. It is responsible for filming and shooting from inside and outside the driver's cabin. When the car is on, the driver can turn on the camera to record events outside the car and store their data in the RAM. The Mis0, MISI, SCK, CS pins of the SD Card module are connected to pins 50 to 53 of the MEGA2560 microcontroller, respectively. The other part is the microphone monitoring system, which starts working when the monitoring algorithm is activated. Of course, this module can also be started separately through the mobile application. For example, when a child or dog is in the car, the microphone can be activated to listen to the car cabin and ensure safety inside the car.

This microphone connects to the SIM808 evb3.2 module and to activate it, just activate this module via GPRS and/or WIFI or by sending an encrypted text message asking the device to call the user number so that the user can hear the sound inside the cabin through his/her mobile phone. transmitter and receiver part, which includes GPS module, GPRS and remote-control module. This section is generally formed in order to receive and send monitoring information such as vehicle location, receiving orders from the user and sending the required information to the user. GPS module is used to receive location signal to know latitude and longitude. This module is integrated with the GPRS module on the SIM808 evb3.2 board. GPRS is used to send and receive SMS to the user or send alert SMS to the nearest police station and send images to the user's email. The SIM808 module is connected to the Rx0 and Tx0 pins via the serial port, also D9 pin connected to pin34 microcontroller. It should be noted that before each command sent to the microcontroller through the GPRS module, in order to increase security, an initial password is always used in order to securely connect the GPRS module to the microcontroller. Here the code * 1234 # is used, which can be changed at the request of the user. After the code is confirmed by the microcontroller, in order to send commands, certain and unique codes have been used to detect it by the microcontroller and in order to perform that process. For example, after sending the initial code * 1234 #, by sending the take picture code, the microcontroller can take a photo and save this photo in the SD Card. Send this photo to the user via email by sending the send mail code. You can also send a loc code through the GPRS module to send a command to the micro to get the geographical location.

In this situation after receiving the command code via GPRS by the microcontroller and command type detection, the microcontroller receives location coordinates from GPRS and sends it to the user via the GPRS module. At this time, the user can receive the location of her/his car instantly by opening the desired SMS via the GOOGLE MAP link. By sending the on code, the microcontroller connects the gasoline and power valves of the car and unlocks the car doors, then unlocks the steering wheel and changes the steering wheel from closed to open.

By sending the off code, the microcontroller cuts off the gasoline and power of the car and locks the car doors, then changes the steering wheel from open to close and activates the steering wheel lock. By sending the start code, the microcontroller starts the car. By sending the call code, the microcontroller makes a voice call with the user, and the user can hear the voice inside the car cabin by answering this call. By sending the change password code, the user can change the device password via SMS. After performing the actions of each command code mentioned above, a text message will be sent to the user stating that these actions have been performed All of the above can be seen in , which is related to the flowchart of the device program algorithm.

The remote control is designed in such a way that the car door opens when the user come close to car. It is called keyless remote control. The remote-control module works as follow: transmitter which is an ASK transmitter module approaches to its receiver board and one of its pins is set. This pin is also connected to microcontroller. So, microcontroller is informed the proximity of the user to the car. At this time, the microcontroller provides the car to the user by applying a monitoring command such as opening the gas valve, opening the door and even opening the steering wheel. Therefore, the time for the driver to ready to use car is minimized. The remote controller module is connected to it via two microcontroller interrupt pins (IN2, IN3). After the user leaves the car and moves away from the transmitter, the remote controller sends a pulse from the receiver to the microcontroller to announce the status of the driver leaving the car. With this message, the controller activates its monitoring algorithm. Monitoring algorithm are Activation of PIR sensor, cut off gas valve, close car doors.

The fourth part includes the WIFI module, the mobile application. This section allows the user to be able to communicate with the car via their mobile phone and activate the surveillance camera and microphone when needed. For example, when the child is in the car or check their location, open and close the door and so on. Almost the same things that could be done with a GPRS module can be done through an application with a WIFI module. The WIFI module is connected to the microcontroller and is the interface between the microcontroller and the user's Android phone. In this part, the main part of the hardware is the same WIFI receiver module that is installed inside the car control board and is connected to the microcontroller. The Wi-Fi transmitter part is the same as the Wi-Fi transmitter of the driver's mobile phone. Here, like in the GPRS module for secure communication, the monitoring code is used for accuracy of communication. For example, to open the doors, the user first sends the initial monitoring code to Wi-Fi, then the door opening code is sent. The send code is located in the application and the user sends it to the microcontroller by pressing a button in the user interface without knowing its contents. The WIFI module is connected serially to the microcontroller and its Rx and Tx pins are connected to Tx3 and Rx3 of the microcontroller, respectively.

The end section of electronic part is the power supply of the device, which is responsible for supplying the required voltage and current flow to each part of the circuit. The primary input of this section is 12-volt car battery. The MEGA2560 microcontroller operates at a voltage of about 8 to 9 volts. On this microcontroller, a 9-volt regulator is installed for this purpose and to supply this voltage through the car's electricity. In the monitoring section, the camera and RAM work with a 5-volt power supply. Also, all switches are powered by 5 volts. Other modules are powered by 12 volts. The PMC4996X switches are powered by 12 volts. It should be noted that all Grounds, modules and switches, etc. are eventually connected to each other. In order to reduce noise in the microcontroller and isolate it, the combination of Bnx and capacitor is used. (Figure-13).

According to claim number 1 and claim number 12, this device has two PIR sensors which are responsible for detecting movement around the car. By activating these sensors (priority with the first received signal), the microcontroller takes the action of taking photos and sending photos and sending warning messages to the user via SMS and call.
Based on claim number 1 and claim number 11, and claim number 12, this device has an SD CARD module. The microcontroller with this module stores photos and videos taken with the camera in the SDCARD and uses GPRS or WIFI modules to send photos and videos in the car to the driver.
According to claim number 1, this device has a designed control board that is responsible to control the disconnection and connection of the car's gasoline valve, door power, and remote start of the car. These works are done by the connection between the designed control board and Microcontroller module with PMOS4996X MOSFET IC and its Starter circuit. This control board is also used to connect micro switches to the microcontroller.
Based on claim number 1, this device has fingerprint sensor which allows each user to save the desired size of their command with their fingerprint, so the user does not need to change the size of the steering wheel to her/his desired size every time she/he uses the car. Each user's fingerprint is stored in the microcontroller's internal memory and is not lost when the car is turned off.
