Embodiment Construction

[0041] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar parameters or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0042] The invention provides a method for reducing the broadband radiation of the whole vehicle and an engine ignition system. Since the ignition system is optimized from two 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 below in conjunction with s...

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 the broadband radiation of a whole vehicle and an engine ignition system. Background technique [0002] At present, according to 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 range is 30MHz~1000MHz. Since the engine ignition system ignites with a lot of energy, if the energy of the ignition system cannot be suppressed, the radiation emission of the whole vehicle will exceed the standard, so that the whole vehicle cannot meet the requirements of the announcement. In order to ensure that the whole vehicle can pass the announcement of the whole vehicle, now mainly The ignition coil is wrapped and shielded with copper foil, such as figure 1 As shown, it is a structural diagram of an engine ignition sy...
