Control strategy and system for intelligent detection of passenger seat safety belts in passenger car

Abstract

The invention discloses a control strategy and system for intelligent detection of passenger seat safety belts in a passenger car. All the passenger seats of the passenger car are divided into a plurality of areas, a controller is configured in each area, and all the controllers are connected to an in-car display and a central control instrument; a pressure switch and a safety belt switch are arranged below each passenger seat, and the pressure switch and the safety belt switch on each passenger seat are connected in series to form an alarm signal detection loop; and one end of each alarm signal detection loop in each area is grounded, and the other end of each alarm signal detection loop in each area is connected to the corresponding controller in the area. The central control instrumentand the in-vehicle display simultaneously display the area number and the seat number of the alarm seat, and multidirectional alarm prompt is conducted, so passengers and drivers are allowed to develop good safety awareness; and the central control instrument prompts alarm information to the drivers, and the in-vehicle display publishes the alarm information to the passengers to enable the passengers to fasten safety belts consciously, so the labor intensity of the drivers and vehicle service personnel is reduced.

Description

Technical field: [0001] The invention relates to an intelligent detection and control strategy and system for seat belts of passengers in passenger cars. Background technique: [0002] Passenger seat belts in the bus market are only used by a small number of safety-conscious people. Bus companies or bus users do not strictly require the use of seat belts, which brings great safety hazards to driving and passengers. Most passenger cars on the market use seat belts with built-in sensors, and a few are equipped with alarm buzzers. When passengers are not wearing seat belts, the signal is transmitted to the instrument to let the driver know; or the built-in buzzer reminds passengers . [0003] The problems and shortcomings of the existing technology for different configurations are analyzed as follows: [0004] 1) All passenger seats have built-in sensors, and the instrument receives alarm signals: [0005] A. Unable to accurately locate the seat number without seat belts; ...

AI Technical Summary

Problems solved by technology

[0015] B. The instrument does not have a large display area, and the vehicle seat layout displayed on the instrument display interface affects the driver's observation of other information on the instrument;

[0016] C. All alarm wiring harnesses need to be extended to instruments or instrument slave stations, and the wiring harnesses are too many and messy
