Embodiment Construction

[0044] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0045] Such as figure 1 As shown, a kind of gear restriction method that is applicable to heavy-duty AMT vehicle that the present invention provides is characterized in that: it comprises the following steps:

[0046] Step 1): Receive the gear limit CAN bus information data, and read the limit gear value;

[0047] Step 2): determine whether the current vehicle gear is greater than or equal to the gear value of three gears lower than the limit gear, if yes, then go to step 3), otherwise go to step 1);

[0048] Step 3): The vehicle sends the gear limit control information TC1, sends A / M mode and P / E mode information according to the received information, and the transmission gear is the received gear value; ...

Abstract

The invention relates to a gear limiting method applied to heavy AMT vehicles. The method is characterized by comprising the following steps: (1), receiving gear limiting CAN bus information data and reading a limited gear value; (2) determining whether a current vehicle gear is greater than or equal to a gear value which is lower than the limited gear by three gears, turning to the step (3) if yes, or turning to the step (1); and (3) sending limited gear control information TC1 via the vehicle and sending information of an A / M mode and a P / E mode according to the received information, wherein the sent gear is a received gear value.

Description

technical field [0001] The invention belongs to the technical field of vehicle electronic control, and in particular relates to a gear limit method suitable for heavy-duty AMT vehicles. Background technique [0002] With the rapid development of the automobile industry, heavy-duty vehicles equipped with AMT gearboxes are more and more recognized by users. Compared with traditional manual transmissions, AMT gearboxes have high transmission efficiency, compact structure, low cost, easy manufacturing, and intelligent shifting. Blocking and easy operation and so on. Compared with the power interruption phenomenon that occurs when manual transmission is shifted, the AMT transmission greatly improves the smoothness of shifting, and improves the shifting speed and driving comfort. [0003] The traditional manual transmission is difficult to meet the operation requirements of the whole vehicle under some special working conditions. The AMT gearbox has functions such as intelligent...
