Abstract

The invention discloses a wireless car body control module. The wireless car body control module comprises a microcontroller, a low-frequency driving circuit and a radio frequency receiving circuit, wherein the low-frequency driving circuit and the radio frequency receiving circuit are connected to the microcontroller, and the low-frequency driving circuit is provided with a plurality of low-frequency antennas for converting current signals into magnetic field signals. The wireless car body control module drives the low-frequency antennas to emit a low-frequency magnetic field through adjustable output current, the magnetic field intensity of the low-frequency magnetic field varies with driving current, high-frequency signals are received through the radio frequency receiving circuit, and the wireless car body control module positions and controls a front wiper blade module, a rear wiper blade module, a left front lamp module, a right front lamp module, a left rear lamp module, a right rear lamp module, a left front door module, a right front door module, a left rear door module, a right rear door module and an instrument module which are arranged on a car body through a bi-directional multi-channel wireless signal channel comprising the low-frequency driving circuit and the radio frequency receiving circuit. The wireless car body control module has the advantages of reducing wiring harnesses on a car, being convenient to install, and improving the reliability.

Description

technical field [0001] The invention relates to a vehicle body control device, in particular to a wireless body control module. Background technique [0002] Automobiles are modern tools.
