Description

Technical Field

[0001] The present invention relates to a vehicle locking control method and system, and more particularly to a vehicle locking control method and system based on the signal strength of a specific electronic device. Background Art

[0002] In recent years, with the advancement of electronic information, the trend of vehicle development has become more and more intelligent. In addition to the basic carrying function, the improvement of safety and more peripheral application functions has also become an issue that the industry is working hard to develop.

[0003] On the other hand, with the rise of environmental awareness and the advancement of electric vehicle technology, the development of electric vehicles powered by electricity to replace traditional vehicles powered by fossil fuels has gradually become an important goal in the automotive field, making electric vehicles more and more popular. Generally speaking, electric vehicles are equipped with more electronic components / devices and can be combined with users' mobile devices to provide more personalized applications and experiences.

[0004] For example, for vehicle users, vehicle theft is always one of the biggest concerns of users. Generally speaking, users must turn off and lock their vehicles whether they are parking them for a long time or for a long time to reduce the chance of theft. The above procedures are cumbersome for users, especially for some users who only need to park their vehicles for a few minutes. On the other hand, vehicle keys can also use electronic technology to achieve more intelligent vehicle management. Summary of the invention

[0005] Therefore, an object of the present invention is to provide a vehicle locking control method that can overcome the above problems.

[0006] Therefore, the vehicle locking control method of the present invention is used for a vehicle. First, a processing unit of the vehicle is used to detect a specific electronic device through a wireless network. When the specific electronic device is detected and connected through the wireless network, it is determined whether a signal strength corresponding to the specific electronic device is greater than a first predetermined value. When the signal strength is greater than the first predetermined value, the processing unit causes the vehicle to enter an unlocked state. Then, it is determined whether the signal strength is less than a second predetermined value, wherein the second predetermined value is less than the first predetermined value. When the signal strength is less than the second predetermined value, the processing unit causes the vehicle to enter a locked state.

[0007] In some embodiments, it is determined whether the vehicle has changed from a riding state to a stationary state within a predetermined period before the current time. When the signal strength is less than the second predetermined value and the vehicle has changed from the riding state to the stationary state within the predetermined period before the current time, the processing unit causes the vehicle to enter the locked state.

[0008] In some embodiments, a sensor unit of the specific electronic device is used to detect a movement amount, and the specific electronic device is used to transmit the movement amount to the processing unit of the vehicle through the wireless network. The processing unit is used to determine whether the movement amount exceeds a predetermined amount. When the signal strength is less than the second predetermined value, the vehicle changes from the riding state to the stationary state within the predetermined period before the current time, and the movement amount exceeds the predetermined amount, the processing unit causes the vehicle to enter the locked state.

[0009] In some embodiments, a sensor unit of the specific electronic device is used to detect a movement amount, and the specific electronic device is used to transmit the movement amount to the processing unit of the vehicle through the wireless network. The processing unit is used to determine whether the movement amount exceeds a predetermined amount. When the signal strength is less than the second predetermined value and the movement amount exceeds the predetermined amount, the processing unit causes the vehicle to enter the locked state.

[0010] In some embodiments, the specific electronic device is used to convert the movement amount into a moving step number. Wherein, determining whether the movement amount exceeds the predetermined amount is determining whether the moving step number exceeds a predetermined step number.

[0011] In some embodiments, when the vehicle enters the locked state, the vehicle cannot be started.

[0012] Another object of the present invention is to provide a vehicle locking control system.

[0013] Therefore, the vehicle control system of the present invention is used for a vehicle, and at least includes a network connection unit and a processing unit. The processing unit uses the network connection unit to detect a specific electronic device through a wireless network. When the specific electronic device is detected and connected through the wireless network, the processing unit determines whether a signal strength corresponding to the specific electronic device is greater than a first predetermined value. When the signal strength is greater than the first predetermined value, the processing unit causes the vehicle to enter an unlocked state. The processing unit determines whether the signal strength is less than a second predetermined value, wherein the second predetermined value is less than the first predetermined value. When the signal strength is less than the second predetermined value, the processing unit causes the vehicle to enter a locked state.

[0014] The above method of the present invention can exist in the form of program code. When the program code is loaded and executed by a machine, the machine becomes a device for implementing the present invention. Therefore, another object of the present invention is to provide a computer program product as described above.

[0015] Therefore, the computer program product of the present invention is loaded by a machine to execute a vehicle locking control method, which is used for a vehicle. The above-mentioned computer program product includes a first program code, a second program code, a third program code, a fourth program code, and a fifth program code. The first program code is used to detect a specific electronic device through a wireless network using a processing unit of the vehicle. The second program code is used to determine whether a signal strength corresponding to the specific electronic device is greater than a first predetermined value when the specific electronic device is detected and connected through the wireless network. The third program code is used to cause the processing unit to cause the vehicle to enter an unlocked state when the signal strength is greater than the first predetermined value. The fourth program code is used to determine whether the signal strength is less than a second predetermined value, wherein the second predetermined value is less than the first predetermined value. The fifth program code is used to cause the processing unit to cause the vehicle to enter a locked state when the signal strength is less than the second predetermined value.

[0016] The effect of the present invention is that the vehicle locking control method and system of the present invention can perform vehicle locking control according to the signal strength of the corresponding specific electronic device, thereby increasing the anti-theft security of the vehicle and the convenience of unlocking.

[0036] Figure 3 The vehicle locking control method according to the embodiment of the present invention is shown. The vehicle locking control method according to the embodiment of the present invention is used in a vehicle.

[0037] First, as in step S310, a specific electronic device is detected through a wireless network. It is worth noting that in some embodiments, the wireless network can be a Wi-Fi, or Bluetooth network, etc. In addition, in some embodiments, the specific electronic device can be paired with the processing unit or the network connection unit of the vehicle in advance, so that the vehicle can know an identification data of the specific electronic device. In some embodiments, the specific electronic device can be a mobile device of the vehicle user, such as a smart device, a beacon, or a wireless key. When the specific electronic device is not detected (No in step S320), the process returns to step S310. When the specific electronic device is detected and connected to the vehicle through the wireless network (Yes in step S320), as in step S330, it is determined whether a signal strength corresponding to the specific electronic device is greater than a first predetermined value. When the signal strength is not greater than the first predetermined value (No in step S330), the process proceeds to step S350. When the signal strength is greater than the first predetermined value (yes in step S330), as in step S340, the processing unit of the vehicle causes the vehicle to enter an unlocked state. It should be noted that, as mentioned above, the locking control of the vehicle can be implemented by hardware or software. The vehicle may be locked in that the vehicle cannot be started / activated, or a specific component of the vehicle, such as a faucet or a tire, is locked and cannot be moved. It is worth noting that the aforementioned locking control of the vehicle is only an example of this case, and the present invention is not limited thereto. When the vehicle enters the unlocked state, it means that the vehicle can be started / activated, or moved.

[0038] Next, as in step S350, determine whether the signal strength corresponding to the specific electronic device is less than a second predetermined value. Note that the second predetermined value is less than the first predetermined value. In some embodiments, the first predetermined value may be -70dbm, and the second predetermined value may be -58dbm. It should be noted that the aforementioned predetermined values ​​are only examples of this case, and the present invention is not limited thereto. When the signal strength is not less than the second predetermined value (No in step S350), the process returns to step S310. When the signal strength is less than the second predetermined value (Yes in step S350), as in step S360, the processing unit causes the vehicle to enter a locked state. As previously mentioned, the locking control of the vehicle can be implemented by hardware or software. When the vehicle enters the locked state, it means that the vehicle cannot be started / activated, or moved.

[0039] Figure 4A vehicle locking control method according to another embodiment of the present invention is shown. The vehicle locking control method according to the embodiment of the present invention is used in a vehicle.

[0040] First, as in step S410, a specific electronic device is detected through a wireless network. Similarly, in some embodiments, the wireless network may be a Wi-Fi or Bluetooth network, etc. In addition, in some embodiments, the specific electronic device may be paired with the processing unit or the network connection unit of the vehicle in advance, so that the vehicle can know an identification data of the specific electronic device. In some embodiments, the specific electronic device may be a mobile device of a vehicle user, such as a smart device, a beacon, or a wireless key. When the specific electronic device is not detected (No in step S420), the process returns to step S410. When the specific electronic device is detected and connected to the vehicle through the wireless network (Yes in step S420), as in step S430, it is determined whether a signal strength corresponding to the specific electronic device is greater than a first predetermined value. When the signal strength is not greater than the first predetermined value (No in step S430), the process proceeds to step S450. When the signal strength is greater than the first predetermined value (yes in step S430), as in step S440, the processing unit of the vehicle causes the vehicle to enter an unlocked state. Similarly, the locking control of the vehicle can be implemented by hardware or software. The vehicle may be locked in that the vehicle cannot be started / activated, or a specific component of the vehicle, such as a handle or a tire, is locked and cannot be moved. It is worth noting that the aforementioned locking control of the vehicle is only an example of this case, and the present invention is not limited thereto. When the vehicle enters the unlocked state, it means that the vehicle can be started / activated, or moved.

[0041] Next, as in step S450, it is determined whether the signal strength of the corresponding specific electronic device is less than a second predetermined value, and whether the vehicle has changed from a riding state to a stationary state within a predetermined period before the current time. Note that the second predetermined value is less than the first predetermined value. In addition, in some embodiments, the processing unit of the vehicle can record the state of the vehicle over time, such as riding or stationary, and retain the vehicle state data for a recent period of time. When the signal strength is not less than the second predetermined value or the vehicle has not changed from the riding state to the stationary state (no in step S450), the process returns to step S410. When the signal strength is less than the second predetermined value, and the vehicle has changed from the riding state to the stationary state within the predetermined period before the current time (yes in step S450), as in step S460, the processing unit causes the vehicle to enter a locked state. Similarly, the locking control of the vehicle can be implemented by hardware or software. When the vehicle enters the locked state, it means that the vehicle cannot be started / activated, or moved.

In some embodiments, the specific electronic device can be a mobile device of the vehicle user, such as a smart device, a beacon, or a wireless key. When the specific electronic device is not detected (no in step S520), the process returns to step S510. When the specific electronic device is detected and connected to the vehicle through the wireless network (yes in step S520), as in step S530, it is determined whether a signal strength corresponding to the specific electronic device is greater than a first predetermined value. When the signal strength is not greater than the first predetermined value (no in step S530), the process proceeds to step S550. When the signal strength is greater than the first predetermined value (yes in step S530), as in step S540, the processing unit of the vehicle causes the vehicle to enter an unlocked state. Similarly, the locking control of the vehicle can be implemented by hardware or software. The vehicle may be locked in that the vehicle cannot be started / activated, or a specific component of the vehicle, such as a faucet or a tire, is locked and cannot be moved. It is worth noting that the aforementioned locking control of the vehicle is only an example of this case, and the present invention is not limited thereto. When the vehicle enters the unlocked state, it means that the vehicle can be started / activated, or moved.

[0044] Next, as in step S550, the vehicle receives a movement amount corresponding to the specific electronic device from the specific electronic device through the wireless network. It is worth noting that in some embodiments, the specific electronic device may have a sensor for detecting the movement amount corresponding to the specific electronic device. The specific electronic device may transmit the detected movement amount to the vehicle through the wireless network. It is worth noting that in some embodiments, the specific electronic device may convert the movement amount into a moving step number, and then transmit the moving step number to the vehicle. As in step S560, it is determined whether the signal strength corresponding to the specific electronic device is less than a second predetermined value, and whether the movement amount corresponding to the specific electronic device exceeds a predetermined amount. It is noted that the second predetermined value is less than the first predetermined value. It should be noted that in some embodiments, the movement amount can be converted into the moving step number. Determining whether the movement amount exceeds the predetermined amount can be determining whether the moving step number exceeds a predetermined number of steps. When the signal strength is not less than the second predetermined value or the movement amount corresponding to the specific electronic device does not exceed the predetermined amount (No in step S560), the process returns to step S510. When the signal strength is less than the second predetermined value, and the movement amount of the specific electronic device exceeds the predetermined amount (Yes in step S560), the processing unit causes the vehicle to enter a locked state, as in step S570. Similarly, the locking control of the vehicle can be implemented by hardware or software. When the vehicle enters the locked state, it means that the vehicle cannot be started / activated or moved.

In some embodiments, the specific electronic device can be a mobile device of the vehicle user, such as a smart device, a beacon, or a wireless key. When the specific electronic device is not detected (No in step S620), the process returns to step S610. When the specific electronic device is detected and connected to the vehicle through the wireless network (Yes in step S620), as in step S630, it is determined whether a signal strength corresponding to the specific electronic device is greater than a first predetermined value. When the signal strength is not greater than the first predetermined value (No in step S630), the process proceeds to step S650. When the signal strength is greater than the first predetermined value (yes in step S630), as in step S640, the processing unit of the vehicle causes the vehicle to enter an unlocked state. Similarly, the locking control of the vehicle can be implemented by hardware or software. The vehicle may be locked in that the vehicle cannot be started / activated, or a specific component of the vehicle, such as a faucet or a tire, is locked and cannot be moved. It is worth noting that the aforementioned locking control of the vehicle is only an example of this case, and the present invention is not limited thereto. When the vehicle enters the unlocked state, it means that the vehicle can be started / activated, or moved.

[0047] Next, as in step S650, the vehicle receives a movement amount corresponding to the specific electronic device from the specific electronic device through the wireless network. Similarly, in some embodiments, the specific electronic device may have a sensor for detecting the movement amount corresponding to the specific electronic device. The specific electronic device may transmit the detected movement amount to the vehicle through the wireless network. It is worth noting that in some embodiments, the specific electronic device may convert the movement amount into a moving step number, and then transmit the moving step number to the vehicle. As in step S660, it is determined whether the signal strength corresponding to the specific electronic device is less than a second predetermined value, whether the vehicle has changed from a riding state to a stationary state within a predetermined period before the current time, and whether the movement amount corresponding to the specific electronic device exceeds a predetermined amount. It is noted that the second predetermined value is less than the first predetermined value. It should be noted that in some embodiments, the processing unit of the vehicle may record the state of the vehicle over time, such as riding or stationary, and retain the vehicle state data for the most recent period of time. Similarly, in some embodiments, the movement amount may be converted into the moving step number. Determining whether the movement amount exceeds the predetermined amount may be determining whether the number of movement steps exceeds a predetermined number of steps. When the signal strength is not less than the second predetermined value, the vehicle does not change from the riding state to the stationary state, or the movement amount corresponding to the specific electronic device does not exceed the predetermined amount (No in step S660), the process returns to step S610. When the signal strength is less than the second predetermined value, the vehicle changes from the riding state to the stationary state, and the movement amount corresponding to the specific electronic device exceeds the predetermined amount (Yes in step S660), as in step S670, the processing unit causes the vehicle to enter a locked state. Similarly, the locking control of the vehicle can be implemented by hardware or software. When the vehicle enters the locked state, it means that the vehicle cannot be started / activated, or moved.
