The present disclosure generally relates to a vehicle trailer light assembly monitoring system. An exemplary system includes a metal oxide semiconductor field effect transistor (MOSFET) connected in series with a light assembly of a vehicle trailer. The voltage driver may be configured by the controller to selectively couple one of a first voltage, a second voltage, or a third voltage to a gate terminal of the MOSFET, the first voltage placing the MOSFET in a resistor mode of operation, the second voltage placing the MOSFET in an on mode of operation, and the third voltage placing the MOSFET in an off mode of operation. In an exemplary embodiment, a controller determines the presence or absence of a vehicle trailer and/or a lamp assembly based on evaluating a voltage drop across the lamp assembly detected by a voltage level detector when the MOSFET is placed in a resistor mode of operation.
本公开总体上涉及一种车辆挂车灯总成监测系统。示例性系统包括与车辆挂车的灯总成串联连接的金属氧化物半导体场效应晶体管(MOSFET)。电压驱动器可由控制器配置以选择性地将第一电压、第二电压或第三电压中的一者耦合到MOSFET的栅极端子,第一电压将MOSFET置于电阻器操作模式、第二电压将MOSFET置于接通操作模式,第三电压将MOSFET置于关闭操作模式。在示例性实施方式中,控制器基于评估当MOSFET置于电阻器操作模式时由电压电平检测器检测到的跨灯总成的电压降来确定车辆挂车和/或灯总成存在或不存在。
