Abstract
Description
[Technical Field]
[0001] The present invention relates to the field of motor vehicle safety protection, and more particularly to systems that prevent motor vehicles from becoming out of control and causing harm to others. [Background technology]
[0002] For example, common motorized vehicles such as personal watercraft, land motorcycles, and automobiles cannot move under their own power unless the driver starts and operates them, but this type of operation actually poses potential dangers. For example, in the case of a personal watercraft, if the driver is thrown from the personal watercraft while riding, the personal watercraft will continue to move forward unless the power of the personal watercraft is cut off, which could cause harm to others. Also, in the case of a land motorcycle, if the driver is thrown from the motorcycle in an accident but the power of the motorcycle is not cut off, the motorcycle will either roll in place or continue moving forward, which could cause harm to other road users and significantly increase the probability of an accident.

[0016] As shown in Figure 1, Figure 1 is a schematic diagram of the system configuration of the present invention. The motor vehicle safety protection system 10 of the present invention is mainly installed in a motor vehicle 11, which may be a mobile body with a power output, such as a jet ski, motorcycle, automobile, or the like, but is not limited thereto.
[0017] In addition, the motor vehicle safety protection system 10 mainly includes a sensing device 101 and a control host system 102, where the sensing device 101 is worn by a user and is used to continuously transmit a sensing signal M1, and the sensing device 101 may be a mobile electronic device that can be worn or carried by a user, such as a bracelet, a watch, or a mobile phone.
[0018] The control host system 102 is connected to the power system 111 of the power vehicle 11 and is used to control the power output of the power system 111. The control host system 102 includes a processing module 1021, a wireless communication sensing module 1022, a distance calculation module 1023, and a safety distance limiting module 1024. The processing module 1021 is coupled to each module and is used to control the operation of each module. The processing module may be a microprocessor, a central processing unit, etc. The wireless communication sensing module 1022 is used to receive the sensing signal M1 emitted by the sensing device 101. The transmission method between the sensing device 101 and the wireless communication sensing module 1022 may be a transmission method such as Bluetooth (registered trademark) transmission or Ultra-Wideband (UWB), and is not limited thereto. The distance calculation module 1023 is used to calculate the distance between the sensing device 101 and the control host system 102 when the wireless communication sensing module 1022 receives the sensing signal M1, and generate distance information M2, which includes the actual distance information between the sensing device 101 and the control host system 102, such as 5 meters, 10 meters, etc. The safe distance limit module 1024 stores at least one set of safe distance threshold M3, and after receiving the distance information M2, the safe distance limit module 1024 compares it to determine whether it exceeds the range of the safe distance threshold M3. If the distance information is greater than the safe distance threshold M3, the safe distance limit module 1024 generates and sends an action command M4 to the processing module 1021.
[0019] 1 , in operation of the present invention, the sensing device 101 is attached to or carried by a user who drives the motor vehicle 11, and the sensing device 101 continuously transmits a sensing signal M1 in a normal state to the wireless communication sensing module 1022 of the control host system 102, allowing the wireless communication sensing module 1022 to continuously detect the sensing signal M1 transmitted by the sensing device 101, ensuring that the distance between the user and the motor vehicle 11 is within a normal range. Furthermore, when the wireless communication sensing module 1022 receives the sensing signal M1 in a normal state, the distance calculation module 1023 calculates the distance between the sensing device 101 and the control host system 102 based on the sensing signal M1, and generates distance information M2, which is the distance between the sensing device 101 and the control host system 102, from the calculated distance, where the distance information M2 is, for example, 5 meters, 10 meters, etc. In addition, after the distance information M2 is generated, it is further transmitted to the safety distance limiting module 1024. The safety distance limiting module 1024 pre-stores at least one set of safety distance thresholds M3. The safety distance thresholds M3 are safety distance parameters, such as 1 meter, 3 meters, etc. When the safety distance limiting module 1024 receives the distance information M2, it compares the distance information M2 with the safety distance thresholds M3 to make a judgment. If the distance information M2 exceeds the safety distance thresholds M3, it means that the current sensing device 101 has already moved a certain distance away from the control host system 102, and this distance has already exceeded the safe range. This indicates that the user driving the motor vehicle 11 may have left the motor vehicle 11 due to an accident or other factors, and the power system 111 of the motor vehicle 11 at this time is still operating. In order to avoid endangering others, the safety distance limiting module 1024 immediately generates an operation command M4 and sends it to the processing module 1021. The processing module 1021 performs a power limiting operation on the power system 111 in accordance with the operation command M4, such as reducing the power or stopping the engine, to prevent the motor vehicle 11 continuing to operate without a driver from endangering others.
[0020] Referring to FIG. 2, in one embodiment, the control host system 102 further includes a timing module 1025, which is coupled to the safety distance limit module 1024 and the processing module 1021 and is used to receive the operation command M4. At least one set of timeout seconds M5 is stored in the timing module 1025. When the safety distance limit module 1024 generates the operation command M4, the operation command M4 is first sent to the timing module 1025 for comparison. After receiving the operation command M4, the timing module 1025 starts timing, generates a time number of seconds M6, and starts comparing whether the time number of seconds M6 is greater than the timeout number of seconds M5. If the time number of seconds M6 is greater than the timeout number of seconds M5, the timing module 1025 sends the operation command M4 to the processing module 1021, causing the processing module 1021 to limit the output of the power system 111 according to the operation command M4.
[0021] Referring to FIG. 3, in one embodiment, the safe distance threshold M3 includes a power limiting threshold M31 and a power cut-off threshold M32, and the safe distance limiting module 1024 checks whether the range of the power limiting threshold M31 or the power cut-off threshold M32 is exceeded after receiving the distance information M2. If the distance information M2 is greater than the power limiting threshold M31, it generates an operation command M4. If the distance information M2 is greater than the power limiting threshold M31 and the power cut-off threshold M32, it generates a cut-off command M7. The processing module 1021 performs a power limiting or power cut-off operation on the power system 111 according to one of the operation commands M4 or the cut-off command M7.
[0022] Referring to FIG. 4, in one embodiment, the control host system 102 includes a rescue module 1026 coupled to a processing module 1021, which shuts down the power system 111 in accordance with a shutdown command M7 and simultaneously drives the rescue module 1026 to transmit a rescue request signal M8 including a rescue request message such as GPS coordinates.
[0023] Referring to FIG. 5, the following are the steps of the method for implementing the motor vehicle safety protection system of the present invention, which should be viewed in conjunction with FIG. Installation step 201: The control host system 102 is installed in the motor vehicle 11, and the control host system 102 is connected to the power system 111 of the motor vehicle 11. Sensing step 202: The control host system 102 receives the sensing signal M1 transmitted by the sensing device 101 through the wireless communication sensing module 1022. Distance calculation step 203: After receiving the sensing signal M1, the distance calculation module 1023 calculates the distance between the sensing device 101 and the control host system 102, and generates corresponding distance information M2. Safe distance comparison step 204: The safe distance limit module 1024 stores at least one set of safe distance thresholds M3, and the safe distance limit module 1024 compares the distance information M2 with the safe distance thresholds M3 to determine whether the distance information M2 exceeds the range of the safe distance thresholds M3. Power limiting step 205: If the distance information M2 is greater than the safe distance threshold M3, the safe distance limiting module 1024 generates an operation command M4, and after receiving the operation command M4, the processing module 1021 performs a power limiting operation on the power system 111 of the powered vehicle 11 to maintain an appropriate distance between the powered vehicle 11 and the sensing device 101.
[0024] Referring to FIG. 6, in one embodiment, the power limiting step 205 has a timing step 2051, including: the control host system 102 receives an operation command M4 and includes a timing module 1025 for storing at least one set of timeout seconds M5; after the processing module 1021 receives the operation command M4, the timing module 1025 starts timing to generate a time second M6; if the time second M6 exceeds the timeout second M5, the processing module 1021 performs power limitation on the power system 111 according to the operation command M4.
[0025] Referring to FIG. 7, in one embodiment, the safe distance comparison step 204 has a command adjustment step 2041, which includes the following: the safe distance threshold M3 includes a power limit threshold M31 and a power cut-off threshold M32; the safe distance limit module 1024 receives the distance information M2 and simultaneously compares it with the power limit threshold M31 and the power cut-off threshold M32; if the power limit threshold M31 is exceeded, an operation command M4 is generated, and the processing module 1021 limits the output of the power system 111 according to the operation command M4; if the power limit threshold M31 and the power cut-off threshold M32 are exceeded, a cut-off command M7 is generated, and the processing module 1021 cuts off the output of the power system 111 according to the cut-off command M7.
[0026] Referring to FIG. 8 , in one embodiment, the power limiting step 205 has a rescue request step 2052 that includes the following: the control host system 102 includes a rescue module 1026 coupled to the processing module 1021, and when the processing module 1021 shuts down the power system 111 in accordance with the shutdown command M7, the rescue module 1026 issues a rescue request signal M8.
[0027] Referring to FIG. 9, FIG. 9 is a schematic diagram of the process steps of another embodiment of the present invention.
[0028] 1 to 8, the steps of this embodiment are as follows. First step S1: The sensing device 101 constantly sends a sensing signal M1 to the wireless communication sensing module 1022 of the control host system 102. Second step S2: The wireless communication sensing module 1022 can continuously detect the sensing signal M1 transmitted by the sensing device 101, and ensure that the distance between the user and the motor vehicle 11 is within a normal range. Third step S3: If the distance calculation module 1023 calculates based on the sensing signal M1 that the sensing distance between the sensing device 101 and the control host system 102 exceeds 3 meters, execute the fourth step S4. Fourth step S4: Following step S3, the user may predefine a distance-time parameter, for example, a range interval of 0 to 3 seconds, and if the time during which the distance exceeds 3 meters is any time within the range of 0 to 3 seconds, for example, exceeds 1 second, execute the fifth step S5; otherwise, execute the sixth step S6. Fifth step S5: Following the fourth step S4, the safety distance limiting module 1024 immediately generates and sends an operation command M4 to the processing module 1021 to avoid endangering others, and the processing module 1021 performs a power limiting operation on the power system 111 according to the operation command M4, thereby limiting the power of the powered vehicle 11 to 30 km / h. Sixth step S6: Following the fifth step S5, if the distance exceeds 3 meters and the time also exceeds the set range, the wireless communication sensing module 1022 continuously detects whether the sensing signal M1 transmitted by the sensing device 101 exceeds 10 meters, and if so, executes the seventh step S7. Seventh step S7: If the distance exceeds 10 meters and the excess time is any time within the range of 0 to 3 seconds, execute an eighth step S8. Eighth step S8: If the detection device 101 worn by the user falls, for example, if the user accidentally drops the detection device 101 while riding in the motor vehicle 11, the distance between the detection device 101 and the motor vehicle 11 will gradually increase, but at this time the user is still riding in the motor vehicle 11. In order to avoid subsequent power restriction operations of the motor vehicle 11, the motor vehicle 11 is provided with a physical alarm release button, and the user must continue to press the alarm release button to maintain the power output of the motor vehicle 11. If the user continues to press the alarm release button, execute the tenth step S10; otherwise, execute the ninth step S9. Ninth step S9: Following the eighth step S8, if the alarm reset button is not continuously pressed, the powered vehicle 11 is powered off and brought to a standstill, and a twelfth step S12 is executed. Tenth step S10: Following the eighth step S8, if the alarm cancellation button is continuously pressed by the user, the powered vehicle 11 detects the sensing signal M1 transmitted by the sensing device 101 through the wireless communication sensing module 1022, and checks whether the distance between the user and the powered vehicle 11 exceeds 10 meters. If it exceeds 10 meters, the eleventh step S11 is executed. Eleventh step S11: Following the tenth step S10, if the distance between the user and the powered vehicle 11 exceeds 10 meters and the alarm cancellation button is continuously pressed, the processing module 1021 performs a power limiting operation on the power system 111 according to the operation command M4, and limits the power of the powered vehicle 11 to 10 km / h, allowing the user to drive at the minimum power. Twelfth step S12: Following the ninth step S9, if the alarm cancellation button is not pressed within a certain period of time, for example, five minutes, after the engine of the powered vehicle 11 is shut off, it indicates that the user may be in distress, and the thirteenth step S13 is executed. Thirteenth step S13: Continuing from the twelfth step S12, in this case, the motor vehicle 11 drives the rescue module 1026 to transmit a rescue request signal M8 including a rescue request message such as GPS coordinates, or transmits a rescue request signal from a mobile electronic device carried by the user himself, to provide rescue to the user.
[0029] In summary, the motor vehicle safety protection system 10 of the present invention mainly monitors the distance between the sensing device 101 and the control host system 102 through each module, and when the driver moves away from the motor vehicle 11, further controls the power output of the motor vehicle 11 to effectively prevent the motor vehicle 11 from causing harm to others.
