Embodiment Construction

[0041] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals represent the same or similar parameters or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary, and are only used to explain the present invention, and cannot be construed as limiting the present invention.

[0042] The invention provides a method for reducing broadband radiation of a whole vehicle and an engine ignition system. Since the ignition system is optimized from the aspects of ignition system layout and ignition energy suppression, the radiation emission energy of the whole vehicle is reduced and meets the requirements of national standards.

[0043] In order to better understand the technical solutions and technical effects of the present invention, specific embodiments will be described in detail ...

Abstract

The invention discloses a method for reducing broad band radiation of a whole vehicle and an engine ignition system. The method comprises the following steps: determining a main disturbance source and a disturbance frequency band which cause standard exceeding of the broad band radiation of the whole vehicle; determining a disturbance transmission path according to the main disturbance source; analyzing the disturbance transmission path and the disturbance frequency band, and determining an electromagnetic compatible rectification and reform program for reducing standard exceeding of the broad band radiation of the whole vehicle; and rectifying and reforming the main disturbance source according to the electromagnetic compatible rectification and reform program. By the method, the problem that standard exceeding of broad band radiation energy of the whole vehicle cannot be reduced simply and effectively in the prior art can be solved.

Description

Technical field [0001] The invention relates to the technical field of electronic control, in particular to a method for reducing broadband radiation of a whole vehicle and an engine ignition system. Background technique [0002] At present, in accordance with the requirements of the National Vehicle Announcement GB 14023-2011, the vehicle broadband radiation emission assessment working condition is the engine speed of 1500±150rpm, and the test frequency band is 30MHz~1000MHz. Since the ignition system of the engine has a large amount of energy during ignition, if the energy of the ignition system cannot be suppressed, the radiation emission of the whole vehicle will exceed the standard, making the whole vehicle unable to meet the requirements of the announcement. The ignition coil is wrapped and shielded with copper foil paper, such as figure 1 Shown is a structural diagram of a prior art engine ignition system. The engine ignition system mainly includes: a battery, an electroni...
