Description

[0001] REFUELING SECURITY SYSTEM

[0002] TECHNICAL FIELD

[0003] The invention relates to a fuel delivery security system that detects and prevents any movement that may occur in the vehicle and ejects the electric cable when movement is detected, in order to prevent damage to the components, the vehicle and people that provide fuel delivery during charging or refueling, to be used in internal combustion, electric and hybrid automatic transmission vehicles.

[0004] PRIOR ART

[0005] With the increasing use of internal combustion, electric and hybrid vehicles today, ensuring the security of these vehicles during charging and refueling has become an important need. Unintentional movement of vehicles poses a danger to user security and can cause damage to equipment such as charging cables and fuel pipes. Although various solutions have been offered in existing techniques to reduce these risks, these solutions contain some important shortcomings.

[0006] In the application numbered US2015057859A1 , if the gear is not in P (Park) mode while the charging cable is connected, it detects the movement with the speed sensor and creates braking force by activating the brake actuator. However, this system is based only on data from the speed sensor and does not have the ability to detect three-dimensional movements (acceleration) of the vehicle. Additionally, it does not offer a mechanical system to prevent damage to the charging cable or a solution to cut off the energy flow for electric vehicles.

[0007] The application CN208393165U uses a controller that intervenes in the braking system to maintain the connection between the charging system and the battery in electric vehicles. This solution also relies only on the braking mechanism and does not provide sufficient sensor diversity to detect the general motion status of the vehicle. Additionally, it does not provide comprehensive security for high-voltage systems and does not offer a solution for physical protection of the charging cable.In the application numbered US2010320018A1 , it intervenes in the mechanical lock system in the vehicle's powertrain using data such as the current from the charger and the open / closed status of the charging door. However, this system does not analyze different data sources such as speed, acceleration and position in an integrated manner.

[0008] Common shortcomings of existing techniques can be summarized as lack of sensor diversity and integration, lack of mechanisms to ensure safe interruption of energy flow, inadequacy of hardware protection systems and incompatibility with wireless charging systems. All these shortcomings pose a major disadvantage in terms of vehicle security, user experience and hardware protection.

[0009] Considering the problems mentioned above, a refueling security system is needed for use in internal combustion, electric and hybrid vehicles, which detects and prevents any movement that may occur in the vehicle and ejects the electrical cable when movement is detected, to ensure that the components that provide refueling, the vehicle and people are not damaged during charging or refueling.

[0010] As a result, all the problems mentioned above have made it necessary to make an innovation in the relevant field.

[0040] DETAILED DESCRIPTION OF THE INVENTIONIn this detailed description, the refueling security system (A) which is the subject of the invention is described with examples that will not form any limiting effect only for a better understanding of the subject.

[0041] The invention relates to the refueling security system (A) which enables the detection and prevention of any movement that may occur in the vehicle in order to prevent damage to the components, the vehicle and people that provide refueling during charging or refueling, to be used in internal combustion, electric and hybrid automatic transmission vehicles. The invention is a computer-based refueling security system (A), and can preferably be configured to be artificial intelligence-based.

[0042] The invention was developed for use in internal combustion, electric, and hybrid automatic transmission vehicles equipped with a three-axis accelerometer (1), speed sensor (2), and GPS antenna (3). The three-axis accelerometer (1) detects acceleration changes in the vehicle's three axes (x-y-z). This allows detection of collisions, rollovers, or sudden movements. The speed sensor (2) determines vehicle speed by measuring the rotational speed of the wheels. The GPS antenna (3) determines the vehicle's location, speed, and route using satellite signals.

[0043] The invention comprises a control unit (4) that detects the movement that will occur in the vehicle and stops the vehicle, as seen in Figure 1. The control unit (4) comprises a data collection module (41) that receives a continuous data stream from the three-axis accelerometer (1), speed sensor (2) and GPS antenna (3) in order to detect the movement that will occur in the vehicle. The control unit (4) comprises a decision module (42) that analyzes the data coming to the said data collection module (41) and determines the movement status of the vehicle. The control unit (4) comprises an intervention module (43) that activates the electric parking brake and puts the gear into park position in order to stop the vehicle when the decision module (42) detects that the vehicle has started moving. The intervention module (43) puts the gear into park position if it is in a different position.

[0044] The invention comprises a contactor (5) positioned between the charging socket and the battery to safely cut off the energy flow when motion is detected by the decision module (42) in electric and hybrid vehicles, as seen in Figure 1.

[0045] The invention comprises a launching mechanism (6) that allows the charging cable to be launched from the charging socket in order to prevent damage to the charging cableand socket when motion is detected by the decision module (42) in electric and hybrid vehicles, as seen in Figure 1. The launching mechanism (6) is configured to be connected to the charging socket. As seen in Figure 2, the launching unit (6) comprises a servo motor (61), a gearwheel (62) rotated by the servo motor (61), and a shaft (63) that moves linearly with the rotational movement of the gear wheel (62). The linear movement of the shaft (63) allows the charging cable to be thrown from the charging socket. The gear wheel (62) allows the shaft (63) to move back and forth on the horizontal axis. The servo motor (61) determines the direction and speed of rotation of the gearwheel (62). The servo motor (61) communicates with the control unit (4). Thus, the servo motor (61) is activated with the signal coming from the control unit (4) and enables the shaft (63) to throw the charging cable from the charging socket.

[0046] In electric and hybrid vehicles equipped with coils developed for charging on roads with wireless charging feature, the control unit (4) receives data flow from the coils in these vehicles to ensure that the vehicle is not stopped (no errors occur) while driving on the road. The coils are connected to the data collection module (41). When the decision module (42) detects that the coils are active, the control unit (4) does not intervene to stop the vehicle and does not activate the contactor (5) and the launching mechanism (6). Thus, a vehicle that is in motion on the road and equipped with a wireless charging feature is not attempted to be stopped. This is because refueling is carried out wirelessly here.

[0047] As seen in Figure 3, if movement is detected in the vehicle while the battery is being charged in electric and hybrid vehicles, the charging cable is thrown, the energy flow is interrupted, the electric parking brake is activated and the gear is shifted to park position. However, if no motion is detected, no intervention occurs. Furthermore, if the coil is equipped with wireless charging, no intervention is necessary. In internal combustion vehicles, if movement is detected during fueling, the electric parking brake is activated, and the transmission is shifted into park. However, if no movement is detected, no intervention takes place.

[0048] The scope of protection of the invention is specified in the appended claims and cannot be limited to what is described in this detailed description for illustrative purposes. Because it is clear that a person skilled in art can come up with similar structures in the light of what is described above without deviating from the main theme of the invention.
