Electronic circuit arrangement structure for monitoring pulse width modulation (PWM) control electronics of control device for brake system of e.g. motor car, has logic circuit to process time of power driver and PWM period duration

摘要

The electronic circuit arrangement structure has power driver (VOx) for switching power path, load (L) and monitoring unit (LTH) of pulse width modulation of output path. The signal output of monitoring unit is electrically connected to signal input of logic circuit (FSM). The logic circuit is provided to process time (t1) of the power driver and the period duration (T) of the PWM and output processed time and the period duration to microcontroller (4). An independent claim is included for method for monitoring pulse width modulation control electronics of control device for brake system mounted in motor vehicle.
