Intelligent control system and anti-pinch method for electric passenger door

Abstract

The invention discloses an electric passenger door intelligent control system and an anti-pinching method. A center processor module, a door opening and closing input signal detection module, a motordetection module, a door position sensor, a temperature sensor, a motor driving module, a nonvolatile memory module, a communication module and a fault indicating module are included, and the door opening and closing input signal detection module, the motor detection module, the door position sensor, the temperature sensor, the motor driving module, the nonvolatile memory module, the communicationmodule and the fault indicating module are all connected with the center processor module. By means of the electric passenger door intelligent control system and the anti-pinching method, the safetyrequirement that a passenger door prevents pinching of personnel can be better met, and the problem that the anti-pinching performance is limited by the environment temperature is solved; the convenience requirement of installing and debugging of the passenger door is better met, and the problem that door opening and closing are not smooth because of different door opening sizes or the manufacturing tolerance is solved; the anti-pinching performance and door opening and closing smoothness reliability requirement in the design life period of a passenger door product is better met, and the problem that because of mechanical service life and abrasion, the anti-clamping performance and the opening and closing smoothness degrade is solved; and meanwhile, maintaining is easy, and the faults of an executing mechanism or an anti-pinching mechanism can be diagnosed and recorded.

Description

technical field [0001] The invention relates to the field of passenger car door control systems, in particular to an intelligent control system for passenger doors and an anti-pinch method. Background technique [0002] With the improvement of people's awareness of environmental protection and the development of new energy technologies, more and more battery-driven models appear in the automotive industry. At the same time, due to the continuous improvement of vehicle battery capacity and energy utilization rate, it is possible for traditional vehicle assemblies (such as passenger doors, air conditioners, etc.) to choose electricity as their power source, and enter the pure electric era along with the vehicle. The use of electricity as a power source also makes it possible to introduce an intelligent electronic control system in the assembly. [0003] The passenger door is one of the basic assemblies of the vehicle. The traditional solution uses air pressure as the power so...
