Abstract
The invention discloses a novel method for eliminating indication errors of automobile instruments. The method comprises that a main controller is in parallel connection with an information collection circuit 1 and an information collection circuit 2 respectively, the information collection circuit 1 collects signal data of sensors, the information collection circuit 2 collects grounding voltage data, then the signal data and the grounding voltage data are input into an algorithm processor simultaneously to be processed, the correct data are determined by the algorithm processor, and correct numerical values are input into the instruments for indication. According to the method, an algorithm combining a two-circuit information data collecting method with computer software is used, so that the correct output data are obtained, the precision of indications of the instruments is controlled, the indication precision of the automobile instruments, especially the fuel and water temperature instruments, can be increased from 50% to 0.5%, the indication precision is improved by 100 times, and the accurate indication data are provided for drivers.
Description
Technical field
The present invention relates to the automobile instrument technical field, be specifically related to a kind of new method that solves the automobile instrument error of indication.
Background technology
Automobile instrument is the most intuitively instrument of in time grasping the automobile duty in driver's driving work, and its numerical value accuracy directly affects the driver to the understanding of vehicle condition.When running car, owing to technical design reason automobile instrument sensor is offset inaccurate technical matters ubiquity because of the instrument indication value that the ground path voltage drift causes, especially the indication of the automobile instrument of fuel oil and water temperature, precision and the accuracy of instrument have been affected, judge that correctly vehicle condition brings inconvenience for the driver, therefore the driver wishes that more accurate automobile instrument can be arranged, and pointing accuracy can satisfy driver's actual needs.
Summary of the invention
The object of the present invention is to provide a kind of new method that solves the automobile instrument error of indication, the present invention adopts the ground offset technology can solve preferably the problem of automobile instrument indicating value skew, makes its pointing accuracy can satisfy the actual needs of human pilot.
For achieving the above object, technical solution of the present invention is: a kind of new method that solves the automobile instrument error of indication comprises the steps: that master controller is in parallel with information acquisition circuit 1 and information acquisition circuit 2 respectively, the signal data of information acquisition circuit 1 pick-up transducers, information acquisition circuit 2 gathers the ground voltage data, then two data enter simultaneously APU and process, determine correct data through APU, the indication of correct value input instrument.
The present invention adopts primary controller simultaneously in parallel with two information acquisition circuits, the signal data of a pick-up transducers, another gathers the ground voltage data, two data are inputted simultaneously APU and are drawn correct data, then be defeated by the instrument indication, because the algorithm that adopts the mode of two-way Information Monitoring data to be combined with computer software, thereby obtain correct output data, and then the degree of accuracy of control instrument indicating value, make especially fuel oil of automobile instrument, the pointing accuracy of water temperature instrument can bring up to 0.5% by original 50%, has improved 100 times, for human pilot provides accurately designation data.
Below in conjunction with the principle of work schematic diagram the present invention is described in further detail.
Description of drawings:
Fig. 1 is principle of work schematic diagram of the present invention.
Embodiment
As shown in the figure, a kind of new method that solves the automobile instrument error of indication comprises the steps: that master controller is in parallel with information acquisition circuit 1 and information acquisition circuit 2 respectively, the signal data of information acquisition circuit 1 pick-up transducers, information acquisition circuit 2 gathers the ground voltage data, then two data enter simultaneously APU and process, determine correct data through APU, the indication of correct value input instrument.
