Description
Technical Field
[0001] This utility model relates to the field of automotive body electronics technology, specifically a body controller module that integrates window position detection. Background Technology
[0002] With the increasing number of new energy electric vehicles, there are new requirements for the cost and function of controllers. Car manufacturers usually use separate window position sensors or integrate control functions through the central control screen, but this method is costly. From the perspective of cost reduction, it can be achieved by integrating window position detection into the body controller.
[0003] Typically, a controller that uses a separate Hall sensor or ripple anti-pinch algorithm and supports one-touch window lifting is required to meet the function of identifying window status. This method is costly. From an economic and practical point of view, a simple window status detection function can be achieved by using this working logic in a body controller that integrates window control. Therefore, a body controller module that integrates window position detection is proposed. Summary of the Invention
