Low-price motor vehicle power window control device and control method thereof

Abstract

The invention provides a device for controlling a power window. The low-price motor vehicle power window control device comprises a microcontroller chip, a connector assembly, a left window rising button, a left window falling button, a right window rising button, a right window falling button, a left relay, a left driving pipe of the left relay, a right relay, a right driving pipe of the right relay, a power circuit, a left window motor current sampling resistor, a right window motor current sampling resistor, a left window motor and a right window motor. The invention further provides a control method based on the low-price motor vehicle power window control device. The advantages that the low-price motor vehicle power window control device is simple in structure and low in cost are fully used, the advantages of being flexible, safe and reliable are achieved, and the low-price motor vehicle power window control device and the control method are particularly suitable for power window control on low-price vehicles such as trucks or light trucks.

Description

technical field [0001] The invention relates to a device for controlling electric windows and a control method thereof, in particular to a low-cost electric window control device and a control method suitable for low-end light trucks that automatically lift and lower the window glass of automobiles, and belongs to automobile technology field. Background technique [0002] With the development of automotive electronics technology, more and more cars, especially passenger cars, have abandoned the traditional hand-operated window regulators, and instead use switches or even microcomputers to control motors to drive the lifting mechanism to control the window lift. Power window controls commonly found in passenger cars or other high-end vehicles are integrated in the body controller (BCM) module; for 4-door cars without a body controller (BCM), each window needs to be controlled by a controller For independent control, the controllers need a local interconnect (LIN) bus or a co...

Problems solved by technology

Power window controls commonly found in passenger cars or other high-end vehicles are integrated in the body controller (BCM) module; for 4-door cars without a body controller (BCM), each window needs to be controlled by a controller Independent control, the controllers need a local interconnect (LIN) bus or a controller area network (CAN) bus to communicate, which is expensive and not suitable for low-priced vehicles such as trucks or light trucks
