Embodiment 1

[0097] This embodiment provides a system for automatically obtaining basic shift parameters, slope resistance calculation parameters, plateau correction parameters and slope correction parameters in the shift prompt function. For details, please refer to figure 1 , which shows a schematic diagram of the acquisition system of the engine shift prompt parameter in this embodiment.

[0098] The system mainly includes data acquisition module, data calculation unit and data output module.

[0099] The function of the data acquisition module is to collect the universal characteristic data of the fuel consumption of the engine after the calibration and optimization of the bench, and the universal characteristic data of the fuel consumption mainly include the engine speed, the opening degree of the accelerator pedal and the average fuel consumption rate of the engine. The data acquisition module can use INCA (Integrated Calibration and Acquisition Systems), ES581 and other devices wit...

Embodiment 2

[0176] This embodiment provides a method for acquiring engine gear shift prompt parameters. For details, please refer to Figure 6 , which shows a flow chart of the method for acquiring the engine shift prompt control parameter in this embodiment.

[0177] After the optimization and calibration of the engine bench is completed, the data acquisition module collects the universal characteristic data of the engine in the full range of working conditions, which specifically includes the engine speed, the opening of the accelerator pedal and the average fuel consumption rate of the engine.

[0178] The data conversion module converts the universal characteristic data of the engine into the universal characteristic data per 100 kilometers (L / 100km) under different gear positions, different pedal openings and different speeds of the vehicle.

[0179] The relationship data between vehicle speed and fuel consumption per 100 kilometers under different gear positions and different pedal...

Abstract

The invention provides an engine gearshift prompt parameter obtaining system and method. The engine gearshift prompt parameter obtaining system comprises a data collection module, a data calculation module and a data outputting module, wherein the data collection module, the data calculation module and the data outputting module are sequentially connected. The data collecting module is used for collecting universal characteristic data of an engine. The data calculation module is used for calculating engine gearshift prompt parameters. The data output module is used for inputting the engine gearshift parameter into an engine management system. After the engine gearshift prompt parameters obtained by the adoption of the engine gearshift prompt parameter obtaining system are applied to gearshift prompt control, the purpose of obviously lowering the oil consumption of the whole vehicle is achieved; besides, the gearshift prompt function control parameters can be rapidly and accurately controlled, the obtained parameters are more objective than those obtained by the adoption of a traditional method, the manpower and material resource cost of a traditional method for obtaining the gearshift prompt function control parameters of an engine control system is significantly lowered, the obtaining efficiency of the gearshift prompt function control parameters is greatly improved, and the parameter obtaining period is shortened.

Description

technical field [0001] The invention relates to the field of engine control, in particular to an acquisition system and an acquisition method of an engine shift prompt parameter. Background technique [0002] With the increasingly stringent regulations on fuel consumption of automobiles, the gear shift reminder function, as a function that can obtain the national vehicle fuel consumption subsidy, is more and more favored by the majority of automobile manufacturers. Recently, the country has officially released the draft of the evaluation method for the energy-saving effect of technical devices outside the cycle of passenger cars, which provides a clear evaluation standard for the fuel-saving effect of the shift reminder function. Affected by this, more and more automobile manufacturers Manufacturers began to develop shift reminder function. It can be foreseen that in the next 3-5 years, the shift prompt function may even become the standard function of manual transmission v...
