Abstract
A monitoring device for protecting against contact or access to a hybrid vehicle having a plurality of high-voltage components and an electronic control unit connected to a low-voltage vehicle electrical system battery. Power actuators for actuating at least one electric machine are connected to a high-voltage battery by way of a power switch. The high-voltage components are monitored by way of a looped circuit and deactivated if the looped circuit is broken. A sensor that is sensitive to magnetic field changes is disposed in or at a removable contact connection of the electric machine or the electronic control unit. The sensor is connected to the looped circuit. A control component of the electronic control unit activates a discharge unit for discharging an energy storage device upon receiving a sensor signal generated by the sensor when the contact connection is broken.
