Electronic control system for doors of city buses

Abstract

The invention relates to an electronic control system for doors of city buses. The electronic control system comprises a door control ECU (Electronic Control System), a photoelectric induction anti-clamping sensor, a door control rocker switch, a vehicle speed sensor, a passenger getting-off prompting module and a power source, wherein the door control ECU (Electronic Control System) is respectively connected with the photoelectric induction anti-clamping sensor, the door control rocker switch, the vehicle speed sensor and the passenger getting-off prompting module, and the power source is respectively connected with the door control rocker switch and the passenger getting-off prompting module. Compared with the prior art, the electronic control system disclosed by the invention has the advantages of increasing the riding safety of passengers and the like.

Description

technical field [0001] The invention relates to an electronic control system for a car door, in particular to an electronic control system for a city bus door. Background technique [0002] At present, domestic bus door control generally adopts electronic control and pneumatic control, but the electronic control is very simple, only a simple switch plus relay control, and the function is single. At the same time, the domestic bus door anti-pinch system generally adopts a delay anti-pinch (the working principle is: when the door pump control system receives the door closing command, it starts timing, and the closing time is extended when the door is caught by a person and is resisted. If within the specified time If the door is not fully closed, the door will automatically open), this anti-pinch method is low in cost and easy to implement, but the clamping force is relatively large, and it is painful to pinch people. Some high-end bus door anti-pinch systems use airbag anti-...

AI Technical Summary

Problems solved by technology

Some high-end bus door anti-pinch systems use airbag anti-pinch (the working principle is: block the two ends of the door sealing strip to form an airbag, from which a trachea is led to the pressure sensor, and the airbag is first compressed when the door is clamped , forming a pressure wave, the pressure sensor sends out the door opening instruction after receiving the pressure wave shock signal, and the door opens automatically), this anti-pinch method is sensitive to anti-pinch and has small clamping force, but its performance is less affected by the hardness and aging of the sealing strip Large, high sealing requirements for the anti-pinch air circuit, there is a certain blind area at both ends of the airbag
