Embodiment Construction

[0009] Such as figure 1 As shown, the dormancy anti-feed control method in the open state of the electric tailgate includes the following steps:

[0010] Step 1. Determine when the whole vehicle is in OFF gear, if not, do not sleep, if so, execute the next step;

[0011] Step 2. Determine whether the tailgate is open and stable, and if so, proceed to the next step;

[0012] Step 3, the RDM stops sending the tailgate status message;

[0013] Step 4. Determine whether there is a message or other wake-up signal on the CAN bus, and if not, perform the next step;

[0014] Step 5. The RDM enters sleep mode. After the vehicle is in normal sleep mode, the quiescent current of the vehicle is less than 0.5mA, so as to avoid problems such as excessive static current of the vehicle when the tailgate is open, and power feeding after the battery continues to discharge, causing the vehicle to fail to start.

[0015] The present invention has been exemplarily described above in conjunction...

Abstract

The invention discloses a dormancy anti-feed control method for an open state of an electric tail gate. When the following conditions are met at the same time, an RDM enters dormancy: condition 1, thewhole vehicle is in an OFF gear; condition 2, the tail door is in an open state; and condition 3, no message exists on the CAN bus. By optimizing the dormancy strategy, the stability of the electrictail gate system and the whole vehicle is improved, and the vehicle use experience of customers is greatly improved.

Description

technical field [0001] The invention relates to the field of automobile electronic control. Background technique [0002] At present, the software sleep strategy of the electric tailgate RDM (electric tailgate control module) in the industry is: when the vehicle is in OFF gear and the tailgate is open, the RDM does not sleep, resulting in excessive static current of the vehicle. If it is too large, the battery will discharge for a long time and feed power, which will cause the vehicle to be unable to use normally and bring great inconvenience to users. Contents of the invention [0003] The invention solves the problem that the static current of the vehicle is too large when the electric tailgate is opened for a long time, which leads to the problem that the vehicle cannot be used due to the power loss of the storage battery. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a dormancy anti-feed control method in th...
