Abstract
The invention discloses a wireless vehicle-body control module which includes a microcontroller and a low-frequency driving circuit and a radio-frequency reception circuit, which are connected to the microcontroller. A plurality of low-frequency antennae for converting current signals into magnetic-field signals are arranged on the low-frequency driving circuit. A control module drives the low-frequency antennae to emit low-frequency magnetic fields through adjustable output current, wherein the magnetic-field intensities change with the driving current. High-frequency signals are received through the radio-frequency reception circuit. A bidirectional multi-channel wireless signal channel comprised of the low-frequency driving circuit and the radio-frequency reception circuit realizes positioning and control of a front windscreen wiper module, a rear windscreen wiper, a left front light module, a right front light module, a left rear light module, a right rear light 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 vehicle body, by the control module. The beneficial effects of the wireless vehicle-body control module are that wire harnesses on a vehicle are reduced, installation is convenient and reliability is improved.
