Controlling method of power lift gate spindle and power lift gate system

Abstract

The invention provides a controlling method of a power lift gate spindle and a power lift gate system. The power lift gate system comprises the power lift gate spindle, wherein the power lift gate spindle comprises a spindle shell, a motor arranged in the spindle shell and a power lift gate controller arranged in the spindle shell; and the power lift gate system also comprises a domain controllerconnected with the power lift gate controller. The method comprises the following steps: collecting operation parameters of the motor arranged in the spindle shell by adopting the power lift gate controller and sending the operation parameters of the motor to the domain controller; and sending power lift gate control commands to the power lift gate controller by the domain controller according tothe operation parameters of the motor based on combination of switch states collected by the domain controller, triggering of pinch strip sensors and a current state of a whole vehicle so that the power lift gate controller controls the power lift gate spindle to be stretched, shrunk or stopped according to the power lift gate control commands. According to the controlling method of the power liftgate spindle and the power lift gate system disclosed by the invention, the failure probability of the power lift gate system can be reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an electric tailgate stay control method and an electric tailgate system. Background technique [0002] Such as figure 1 As shown, the current electric tailgate system of the car includes a support rod (Spindle), a right / left anti-pinch strip (RH / LH Pinch Strip Sensor), a switch (Switch), a suction lock motor / unlock motor (Closure / Releasemotor ) and other devices, as well as the power lift gate controller (Power Lift Gate Module, PLGM) connected to each system. PLGM is respectively connected with each device to realize the acquisition of corresponding signals in each device and the control of corresponding mechanisms. [0003] For the current electric tailgate system of automobiles, in the process of controlling the opening and closing of the electric tailgate, the PLGM completely controls the electric tailgate strut to expand and contract according to the corresponding sig...

Problems solved by technology

[0003] For the current electric tailgate system of automobiles, in the process of controlling the opening and closing of the electric tailgate, the PLGM completely controls the electric tailgate strut to expand and contract according to the corresponding signals collected from various devices, and the PLGM and the electric tailgate Each device in the door system is connected through a wiring harness. The more wiring harnesses are connected, it not only increases the cost, but also increases the failure probability of the electric tailgate system of the car.
