specific Embodiment approach 1

[0033] Specific implementation mode one: refer to figure 1 This embodiment is specifically described. A method for configuring a vehicle speed ratio of an automobile combination meter described in this embodiment includes the following steps:

[0034] Step 1: Store a fixed speed ratio information in the EEPROM of the instrument, and set the flag bit Flag=0;

[0035] Step 2: When the ignition switch is in the ON position, the meter communicates with the BCM, and if the communication is successful, execute Step 3;

[0036] If the communication fails, the LCD screen of the instrument will prompt the speed communication failure, and go to step 4;

[0037] Step 3: The instrument checks with the BCM. If the test is successful, the instrument receives the speed ratio information sent by the BCM, and uses the speed ratio information sent by the BCM to update the speed ratio information in the EEPROM, that is, the configuration is completed.

[0038] The specific steps for updating t...

Abstract

The invention discloses a method for configuring the speed ratio of an automobile combination instrument, relates to the technical field of automobile instruments, and aims to solve the problem that the same instrument cannot adapt to different automobile types in the prior art. The speed ratio of the automobile combination instrument is configured in a BCM and diagnostic instrument combination mode, the purpose that the same instrument is matched with different automobile types is achieved, the success rate of speed ratio configuration is effectively increased, the whole automobile off-line operation process can be reduced to the maximum extent through the priority design of the two modes. And the workload of workers in an automobile factory is reduced, and the finished automobile offline speed is increased.

Description

technical field [0001] The invention relates to the technical field of automobile instruments, in particular to a method for configuring vehicle speed ratios of an automobile combination instrument. Background technique [0002] Most of the traditional instrument clusters adopt the method of fixed speed ratio. However, with the continuous increase of car models and the continuous upgrading of configurations, higher requirements are put forward for the design of car instrument clusters. In order to make the same instrument adapt to different models , the speed ratio of most of the combination instruments currently designed is configurable. In order to make the instrument more versatile and ensure that the instrument can output vehicle speed information stably when matching different models, it is necessary to design a more efficient, The method of stable speed ratio configuration. Contents of the invention [0003] The object of the present invention is to propose a method...
