Abstract

The invention provides an interference filtering circuit of a steering wheel and an electric automobile and relates to the technical field of electric automobiles. The interference filtering circuit of the steering wheel comprises a power supply module, a signal acquisition port, a backlight power supply module and a communication module which are respectively connected with a steering wheel controller, and a first filter circuit which is connected with the power supply module; a second filter circuit is connected between the signal acquisition port and the steering wheel controller; a third filter circuit which is connected between the backlight power supply module and the steering wheel controller; a fourth filter circuit which is connected with the communication module; wherein the backlight power supply module is connected with a plurality of backlight modules. According to the interference filtering circuit, electromagnetic interference of the steering wheel can be effectively filtered out, signal jumping of the intelligent cabin system caused by noise generated by different paths is restrained, and a safe, reliable and comfortable driving environment is created for a driver.

Description

Technical field [0001] The present invention belongs to the field of electric vehicles, in particular, to a steering wheel controller interference filtering circuit and an electric vehicle. Background technique [0002] The car is a transportation for people to travel, and the steering wheel is the user's safety, the key components that do not exercise correctly. When the automatic driving has not been effectively applied, in order to drive safely, the user should always hold the steering wheel. However, with the advancement of technology, the audio and video entertainment system on the vehicle is also gradually diversified, and the user can experience the convenience of the smart cockpit system when manipulating the vehicle, while making the operation more secure, efficient, in the steering wheel More and more control buttons are integrated. [0003] The structure and space of the steering wheel are limited. In order to achieve more control functions, the traditional way to conn...
