Embodiment Construction

[0024] Such as figure 1 Shown, a kind of shift prompting method of automobile meter, comprises:

[0025] S101. Pre-storing data: pre-storing data corresponding to accelerator opening, upshift vehicle speed thresholds of various levels and downshift vehicle speed thresholds of various levels.

[0026] Specifically, the data corresponding to the throttle opening, upshift vehicle speed thresholds of each level and downshift vehicle speed thresholds of each level is prestored in the form of a table, and the corresponding curves are shown in image 3 , the x-axis is the vehicle speed threshold, and the y-axis is the throttle opening.

[0027] According to the above corresponding data, the corresponding vehicle speed threshold can be found through the accelerator opening.

[0028] S102. Acquisition of thresholds: according to the current and previous accelerator openings, corresponding upshift vehicle speed thresholds of various levels and downshift vehicle speed thresholds of var...

Abstract

The invention relates to a gear shifting reminding method and a gear shifting reminding system for an automobile instrument. According to the gear shifting reminding method and the gear shifting reminding system disclosed by the invention, through the opening degree of a throttle and a vehicle speed signal, which need to be received by the instrument originally, operation is completed on the instrument, and reminding is completed, so that the time delay of signal transmission is reduced, and the real-time capacity is good; under the situation that the current real gear information is not obtained, a gear shifting reminding function is realized and is easy to realize; and the number of corresponding sensing devices is reduced, so that the cost is low.

Description

technical field [0001] The invention belongs to the technical field of automobile electronics, and in particular relates to a method and system for prompting shifting of automobile meters. Background technique [0002] At present, the gear shift prompt technology is to obtain the current real gear position through the CAN bus, and calculate the target gear position through the corresponding sensor device, and finally transmit it to the instrument and display it. Time delays are easy to occur in signal transmission, and the real-time performance is not good. Contents of the invention [0003] Based on this, aiming at the above-mentioned technical problems, a method and a system for prompting shifting of an automobile instrument are provided. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005] A gear shift prompt method for an automobile instrument, comprising: [0006] Prest...
