Controller for vehicle lighting passes microcontroller control output to controlled component if microcontroller working normally or passes clock signal to component if microcontroller faulty

摘要

The device has at least one microcontroller for controlling at least one electronically controlled component with a clocked control signal. It has a circuit with a monitoring stage for a microcontroller output signal and a clock generator stage. The circuit passes the control output of the microcontroller to the controlled component if the microcontroller is working normally or passes the clock signal to the component if the microcontroller is faulty. The device has at least one microcontroller (1) for controlling at least one electronically controlled component (8), especially an electronic switch, with a clocked control signal. It has a circuit with a monitoring stage (2) for a microcontroller output signal and a clock generator stage (5). The circuit passes the control output of the microcontroller to the controlled component if the microcontroller is working normally or passes the clock signal to the component if the microcontroller is faulty.
