Translational lift control system and control method for airbag-driven trailer

Abstract

The airbag-driven trailer translational lifting control system and control method of the present invention include a signal acquisition unit, an airbag drive unit and a controller unit, the signal acquisition unit includes a proximity switch, a sensing area and an attitude sensor, and the airbag drive unit includes three Position two-way valve, opening valve and pneumatic latch, the proximity switch collects the chassis position signal through the sensing area and transmits the electrical command to the controller unit, the controller unit controls the action of the pneumatic latch according to the electrical command and then controls the inflation and deflation of the airbag The sensor collects the tilt angle information of the trailer chassis and sends it to the controller unit. The controller unit controls the action of the three-position two-way valve and the opening valve according to the obtained chassis tilt angle information to control the inflation and deflation rate. The invention adopts the control air bag to inflate and deflate to carry out the loading and unloading process, and the lifting is stable. Due to the cushioning performance of the air bag, the trailer can also effectively reduce the damage to the transport vehicle caused by vehicle bumps during the transportation process.

Description

technical field [0001] The present invention relates to a trailer control system and method, in particular to a translational lift control system and control method for an airbag-driven trailer. Background technique [0002] With the development of the economy and the increase of income level, the possession of private cars is getting higher and higher. With the increase of the possession of private cars, the incidents of vehicle breakdown or vehicle damage caused by traffic accidents are also greatly increased, and therefore the use of trailers Also grows accordingly. The current trailer mainly lifts the vehicle by lifting, pulling or lifting. This method is not only time-consuming and labor-intensive, but also easily causes secondary damage to the vehicle. Moreover, the lifting performance of the existing trailers is still not up to people. At the same time, the ride comfort of existing trailers is poor during driving, and relying on the lock to lock the faulty car also h...
