Problems solved by technology

Because this method is based on the whole vehicle, it is costly and economical; and in the trial production stage of the prototype, the resources of the whole vehicle are scarce, and all departments need to share them, which often causes delays in the test progress and hinders the testing and development of the electric rear cover system. bring adverse effects

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. Note that the aspects described below in conjunction with the drawings and specific embodiments are only exemplary, and should not be construed as limiting the protection scope of the present invention.

[0019] figure 1 It shows the connection structure of the embodiment of the electric back cover durability test bench of the present invention. See figure 1 , the stand of the present embodiment includes a rear cover button handle, a rear cover lock, a lock actuator, a rear cover closing button, an electric spring, a rear cover controller (HDSG), a body controller (BCM) and a non-vehicle controller (TBH ). The connection relationship between these components is: BCM is connected to the back cover button handle through the trigger signal line S1 of the handle button, BCM is connected to TBH through a pin (for example, KL15 pin), and BCM is co...

Abstract

The invention discloses an electric-rear-cover durability test bench. An electric-rear-cover durability test can be implemented on a body in white, experiment with an entire vehicle is avoided, and test cost is remarkably reduced; the technical scheme includes that a mode that a BCM (body control module) and a HDSG and are combined with a non-on-board controller (TBH) forms a control system of the test bench; only one type of a CAN data bus is related, so that a gateway can be bypassed, and direct access to a vehicle diagnosis port is achieved to perform detection on the running state of an electric rear cover.

Description

technical field [0001] The invention relates to the field of electric rear covers of automobiles, in particular to a stand capable of carrying out endurance tests on electric rear covers of automobiles. Background technique [0002] The car electric back cover is generally composed of back cover sheet metal and accessories, electric springs, integrated locks, lock actuators, buzzers and related vehicle controllers. Functions such as memory and safety protection, the overall control logic is more complicated. When some vehicle controllers or sensors are missing, the body controller (BCM) and the electric tailgate controller (HDSG) will judge that the vehicle is driving or other conditions that are not suitable for opening the tailgate, thus triggering its safety protection function , causing the electric rear cover to fail to open and close normally. Therefore, the current common practice in the durability test of the electric rear cover is to directly use the whole vehicle...
