Abstract

The invention discloses an interference signal filtering device, an automobile and an interference signal filtering method thereof. The device comprises a first filtering unit and a second filtering unit, wherein the first filtering unit is configured to filter out an electromagnetic interference signal in an input control signal to obtain a first control signal; the control signal is a control signal for an interference signal is to be filtered; the control signal comprises a wake-up signal of a vehicle control unit of the automobile; the second filtering unit is configured to filter out a strong current interference signal in the first control signal to obtain a second control signal, and the second control signal is used as an effective control signal after the interference signal is filtered from the control signal. According to the scheme, the electromagnetic interference in the control signal of the electric control unit of the automobile is filtered out, so that the control reliability of the electric control unit is improved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to an interference signal filtering device, an automobile and an interference signal filtering method thereof, in particular to an on-board wake-up circuit for automatically filtering out interference signals, an automobile and an interference signal filtering method thereof. Background technique [0002] With the rapid development of science and technology, new energy vehicles have gradually entered people's lives. The electronic control unit (such as the vehicle controller (VCU)) of a new energy vehicle is composed of various electronic components. Various electronic components will generate a lot of electromagnetic interference when working, and in severe cases, it will cause the circuit controlled by the electronic control unit to Misoperation has a major safety hazard. [0003] The above content is only used to assist in understanding the technical solution of ...
