The motion sensor 11 is used to detect driving information of the vehicle 1. In one embodiment, the motion sensor 11 is a speed sensor, and the driving information includes, but is not limited to a driving speed of the vehicle 1.
The monitor system 10 is used to ensure safety of a driver when the driver is driving the vehicle 1. In one embodiment, the monitor system 10 protects the driver by controlling the seat belt pretensioner 12 to tighten the seat belt 121 with a predetermined tension value. In one embodiment, the predetermined tension value corresponds to the driving information.
The storage device 13 can be an internal storage device, such as a flash memory, a random access memory (RAM) for temporary storage of information, and/or a read-only memory (ROM) for permanent storage of information. The storage device 13 can also be an external storage device, such as an external hard disk, a storage card, or a data storage medium. The at least one processor 14 can be a central processing unit (CPU), a microprocessor, or other data processor chip that performs functions of the vehicle 1.
In at least one embodiment, the monitor system 10 can include a setting module 101, an obtaining module 102, a determination module 103, and a control module 104. The function modules 101-104 can include computerized codes in the form of one or more programs, which are stored in the storage device 13, and are executed by the at least one processor 14 to provide functions of the present disclosure. Details will be given in the following paragraphs.
The setting module 101 predetermines a plurality of tension values corresponding to different driving information, for the seat belt pretensioner 12. As mentioned above, the driving information includes the driving speed of the vehicle 1. In one embodiment, the setting module 101 can preset a speed range corresponding to each of the plurality of tension values.
For example, the setting module 101 predetermines a first tension value (for example, 0 Newton (N)) for the seat belt pretensioner 12, when the driving speed of the vehicle 1 is less than 50 kilometers per hour (km/h).
For another example, the setting module 101 predetermines a second tension value (for example, 2 N) for the seat belt pretensioner 12, when the driving speed of the vehicle 1 is within a speed range of about 50 km/h to about 80 km/h. The setting module 101 predetermines a third tension value (for example, 4 N) for the seat belt pretensioner 12, when the driving speed of the vehicle 1 is within a speed range of about 80 km/h to about 120 km/h. The setting module 101 further predetermines a fourth tension value (for example, 6 N) for the seat belt pretensioner 12, when the driving speed of the vehicle 1 is greater than 120 km/h.
The obtaining module 102 obtains the driving information from the motion sensor 11. In one embodiment, the motion sensor 11 can be the speed sensor. For example, the obtaining module 102 obtains the driving speed from the motion sensor 11.
The determination module 103 determines a tension value for the seat belt pretensioner 12 according to the driving information. For example, the determination module 103 determines the third tension value (for example, 4 N) for the seat belt pretensioner 12, when the driving speed of the vehicle 1 is within the speed range of about 80 km/h to about 120 km/h.
The control module 104 controls the seat belt pretensioner 12 to tighten the seat belt 121 of the vehicle 1 with the tension value determined by the determination module 103. For example, the control module 104 controls the seat belt pretensioner 12 to tighten the seat belt 121 with the third tension value, when the driving speed of the vehicle 1 is within the speed range of about 80 km/h to about 120 km/h.
At block 1001, a setting module predetermines a plurality of tension values corresponding to different driving information, for a seat belt pretensioner of a vehicle.
In one embodiment, the driving information includes a driving speed of the vehicle. In one embodiment, the setting module can preset a speed range corresponding to each of the plurality of tension values. For example, the setting module predetermines a first tension value (for example, 0 Newton (N)) for the seat belt pretensioner, when the driving speed of the vehicle is less than 50 kilometers per hour (km/h).
For another example, the setting module predetermines a second tension value (for example, 2 N) for the seat belt pretensioner, when the driving speed of the vehicle is within a speed range of about 50 km/h to about 80 km/h. The setting module predetermines a third tension value (for example, 4 N) for the seat belt pretensioner, when the driving speed of the vehicle is within a speed range of about 80 km/h to about 120 km/h. The setting module further predetermines a fourth tension value (for example, 6 N) for the seat belt pretensioner, when the driving speed of the vehicle is greater than 120 km/h.
At block 1002, an obtaining module obtains the driving information from a motion sensor of the vehicle. In one embodiment, the motion sensor can be a speed sensor. For example, the obtaining module obtains a driving speed from the motion sensor.
At block 1003, a determination module determines a tension value for the seat belt pretensioner according to the driving information. For example, the determination module determines the third tension value (for example, 4 N) for the seat belt pretensioner, when the driving speed of the vehicle is within the speed range of about 80 km/h to about 120 km/h.
At block 1004, a control module controls the seat belt pretensioner to tighten a seat belt of the vehicle with the tension value. For example, the control module controls the seat belt pretensioner to tighten the seat belt with the third tension value, when the driving speed of the vehicle is within the speed range of about 80 km/h to about 120 km/h.
