Design method and device of vehicle universal instrument capable setting parameter

Abstract

The invention discloses a method for designing a vehicle universal instrument with settable parameters, which comprises the following step: when an instrument is started, if a trigger signal is determined to be searched, performing parameter setting operations and storing the parameter after setting for the convenience of invocation. The invention also provides a device for designing the vehicle universal instrument with the settable parameters corresponding to the method, which comprises the following components: a triggering unit which is used for sending the trigger signal for starting the parameter setting operations of the instrument, a first control unit which is used for sending a parameter setting command of the instrument if the trigger signal is determined to be searched when the instrument is started, a first setting unit which is used for performing the parameter setting operations of the vehicle universal instrument when the parameter setting command of the instrument is received, and a first storage unit which is used for storing the parameters after setting for the convenience of invocation. The method and the device can decrease the amount of the instrument model to further reduce the workload of an automobile factory and an instrument manufacturing plant, the control difficulty of production logistics, and the turnover pressure of production stock fund.

Description

technical field [0001] The invention relates to a general automobile instrument, in particular to a design method and a device for an automobile general instrument whose parameters can be set. Background technique [0002] In order to better adapt to the market, automobile manufacturers try their best to meet the different needs of different customers and provide customers with multiple choices. Therefore, they often provide multiple configurations for the same car, especially the engine, gearbox, rear axle, and tires of the car. And other accessories often set different configurations according to the different needs of customers. For example, the engine speed signal depends on the engine, some engines have 110 teeth (that is, the engine outputs 110 pulse signals per revolution), some have 12 teeth, some have 138 teeth, etc.; the vehicle speed signal depends on the gearbox , rear axle, tires, etc., when the configuration changes, the vehicle speed ratio will change, some a...

AI Technical Summary

Problems solved by technology

[0004] At present, due to technical limitations, the functional parameters of automobile instruments are fixed. Instrument manufacturers produce a variety of instruments with different functional parameters, which are distinguished by different models, and are stored one by one for external supply. Ordering these meters with different functional parameters distinguished by different models, in actual production, this obviously increases the workload for both the automobile manufacturing plant and the instrument manufacturing plant, and increases the difficulty of controlling production logistics and the turnover pressure of production reserve funds
