The invention discloses a directly-on-load automobile switch control system. In the directly-on-load automobile switch control system, a demisting module, a door lock module, a rearview mirror moduleand a glass lifting module are integrated on the switch; a circuit is mainly composed of an on-off keying circuit, an MCU, a demisting motor driver, a glass lifting motor driver, a rearview mirror motor driver, a signal detection amplification circuit, a state indication module and a bias voltage generation circuit; and the MCU judges passenger requirements by detecting signals of the output end of the keying circuit and sends control signals to corresponding driving units to drive motors to act. According to the control system, the motors are directly controlled, and the requirement on a BCMis low; and besides, KIA70N06L chips are adopted to drive the motors, compared with a traditional relay, the chips are smaller in size and capable of bearing larger current and have higher developmentvalue in the compact structure space of the automobile switch, and a certain application prospect is achieved.
本发明公开了一种直接带载的汽车开关控制系统。本发明为一种直接带载的汽车开关控制系统,该开关上集成了除雾模块、门锁模块、后视镜模块和玻璃升降模块;电路主要由开关按键电路、MCU控制器、除雾电机驱动、玻璃升降电机驱动、后视镜电机驱动、信号检测放大电路、状态指示模块、偏置电压产生电路组成;MCU控制器通过检测按键电路输出端的信号来判断乘客需求,向对应的驱动单元发送控制信号,驱动电机动作,本控制系统直接控制电机,对车身BCM要求较低,并且采用的是KIA70N06L芯片驱动电机,与传统的继电器相比,该芯片体积更小,承受的电流更大,在汽车开关紧凑的结构空间里有更大的开发价值,具备一定的使用前景。
