The invention relates to a driving safety monitoring system and method.

With the advancement of the times, the increase and popularity of automobiles and the upgrading of them have led to better and better car configuration and performance. However, changes in driving speed caused by factors such as road conditions often cause the driver's safety during driving to be difficult to guarantee.

In view of the above, it is necessary to provide a driving safety monitoring system and method, which can control the contraction strength of the seat belt retractor device of the vehicle according to the instantaneous driving parameters of the vehicle, thereby enhancing driving safety.

A driving safety monitoring system, running in a vehicle, the system comprising: an obtaining module, configured to acquire driving parameters of the vehicle; and a determining module, configured to determine the safety of the vehicle according to the obtained driving parameters a contraction force with a pre-shrink device; and a control module for controlling the seat belt pre-shrink device to contract the seat belt with the determined contraction force.

A driving safety monitoring method is applied to a vehicle, the method comprising: obtaining a step of acquiring a driving parameter of the vehicle; determining a step of determining a seat belt pre-shrinking device of the vehicle according to the obtained driving parameter a contraction force; and a control step of controlling the seat belt retractor device to contract the seat belt with the determined contraction force.

Compared with the prior art, the driving safety monitoring system and method of the present invention can control the contraction strength of the seat belt pre-shrinking device of the vehicle according to the instantaneous driving parameters of the vehicle, thereby enhancing driving safety.

1 is a schematic diagram of an operating environment of a preferred embodiment of the driving safety monitoring system of the present invention.

2 is a flow chart of a preferred embodiment of the driving safety monitoring method of the present invention.

Referring to FIG. 1 , it is a schematic diagram of an operating environment of a preferred embodiment of the driving safety monitoring system (hereinafter referred to as monitoring system) of the present invention. The monitoring system 10 operates in the vehicle 1 . The vehicle 1 further includes, but is not limited to, a vehicle speed sensor 11, a seat belt pre-shrink device 12, a reservoir 13, and a processor 14.

In the present embodiment, the monitoring system 10 is shown to control the seat belt retractor device 12 to shrink the seat belt with a predetermined contraction force according to the current driving parameters of the vehicle 1 to maintain the driver's driving process. Safety. In this embodiment, the driving parameter may be the driving speed sensed by the vehicle speed sensor 11 .

The storage 13 can be used to store the code and data of the monitoring system 10. In this embodiment, the monitoring system 10 can be divided into one or more modules, and the one or more modules are stored in the storage 13 and executed by the processor 14 to implement the present invention. The functionality provided by the invention. In this embodiment, the monitoring system 10 can be divided into a setting module 101, an obtaining module 102, a determining module 103, and a control module 104. The module referred to in the present invention is a program segment capable of performing a specific function, and is more suitable for describing the execution process of the software in the mobile terminal 1 than the program. The detailed functions of each module will be made in conjunction with the flowchart of FIG. 2. specific description.

Referring to FIG. 2, it is a flow chart of a preferred embodiment of the driving safety monitoring method of the present invention. The order of execution of the steps in the flowchart shown in FIG. 2 may be changed according to different requirements, and some steps may be omitted.

In step S1, when the setting module 101 presets that the driving parameters of the vehicle 1 belong to different parameter ranges, the different sizes of the contraction strength of the seat belt pre-shrink device 12 are corresponding.

For example, when the driving parameter of the vehicle 1 includes the driving speed of the vehicle 1 , the setting module 101 may preset that the driving speed of the vehicle 1 belongs to different speed value ranges, corresponding to the The different sizes of the contraction strength of the belt retractor device 12.

For example, when the driving speed of the vehicle 1 is preset to be less than 50 km/h (km/h), the contraction force of the seat belt pre-shrink device 12 is 0 N (N), that is, not activated. The seat belt pretensioner device 13. When the driving speed of the vehicle 1 is preset to be [50 km/h, 80 km/h], the belt retractor device 12 has a contraction force of 2 N. When the driving speed of the vehicle 1 is preset to be (80 km/h, 120 km/h), the contraction force of the seat belt pre-retractor device 12 is 4 N. The driving speed of the vehicle 1 is preset. When it is greater than 120 km/h, the belt retractor device 12 has a contraction force of 6N.

In step S2, the acquisition module 102 obtains the driving parameters of the vehicle 1.

Still taking the driving parameters of the vehicle 1 including the driving speed of the vehicle 1 as an example, the acquisition module 101 can acquire the driving speed of the vehicle 1 from the vehicle speed sensor 12 of the vehicle 1 immediately.

In step S3, the determining module 103 determines the contraction strength of the seat belt pre-shrink device 13 according to the acquired driving parameters.

For example, when the acquired driving speed of the vehicle 1 is 30 km/h and the driving speed of the vehicle 1 is preset to be less than 50 km/h (km/h), the seat belt pre-shrinking device When the contraction force of the device 12 is 0N, the determining module 102 determines that the contraction force of the seat belt pre-shrink device 12 is 0, that is, the seat belt pre-shrink device 12 is not required to be activated. For another example, when the traveling speed of the acquired vehicle 1 is 100 km/h, and the driving speed of the vehicle 1 is preset to be (80 km/h, 120 km/h), the seat belt pre- When the contraction force of the retractor device 12 is 4N, the determination module 102 determines that the contraction force of the seat belt pre-shrink device 12 is 4N.

In step S4, the control module 104 controls the seat belt pre-shrink device 13 to contract the seat belt with the determined contraction force.

It should be noted that the above embodiments are only for explaining the technical solutions of the present invention and are not intended to be limiting, although the present invention will be described in detail with reference to the above preferred embodiments, those of ordinary skill in the art Modifications or equivalents of the embodiments are not to be construed as a departure from the spirit and scope of the invention.
