Problems solved by technology

[0013] A relatively small object having a size of, for example, 30×60 mm or less in thickness and width, or a small body part of a passenger is caught in the sliding door and cannot be sensed due to small pressure, and thus, The closing operation of the sliding door continues and damages objects or injures passengers
Additionally, accidents can occur if the vehicle is driven with passengers trapped in the sliding doors

Abstract

A sliding door device for a motor vehicle includes a slidably movable sliding door, a door weather strip attached to the sliding door, and a vehicle body weather strip tightly attached to the door weather strip to maintain airtightness in a state in which the sliding door is closed. A pressure switch senses an internal pressure of the door weather strip, and a pneumatic line connects the door weather strip and the pressure switch such that they communicate with each other. An electronic control unit (ECU) controls an opening and closing operation of the sliding door upon receiving a sensing signal from the pressure switch, and an opening and closing valve allows the pneumatic line to communicate with atmospheric pressure or closes the pneumatic line to atmospheric pressure. An object or a passenger is effectively prevented from being caught when a sliding door is being closed.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2013-0021302 filed with the Korean Intellectual Property Office on February 27, 2013, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to a sliding door apparatus for a vehicle, and more particularly, to a sliding door apparatus for a vehicle capable of preventing objects or passengers from being caught in the sliding door when the sliding door is closed. Background technique [0004] Generally, a large commercial vehicle such as a bus employs a sliding door arrangement to allow passengers to easily get on or off the vehicle. [0005] The sliding door apparatus includes a sliding door that moves along guide rails provided in the vehicle to open and close a door opening (door opening) formed in the vehicle. The pneumatic cylinder is the power source for moving t...
