Abstract:
1. A monitoring device for providing protection against electrical shock in a hybrid vehicle having a plurality of high-voltage components, an electronic control unit connected to a low-voltage vehicle electrical system battery, and power actuators connected to a high-voltage battery via a power switch and configured to actuate at least one electric machine, the monitoring device comprising: a loop circuit for monitoring the high-voltage components and for deactivating the high-voltage components when said loop circuit is opened; a magnetic-field-sensitive sensor disposed at a releasable contact connection of the electric machine and/or of the electronic control unit, said magnetic-field-sensitive sensor generating a sensor signal when the releasable contact connection is released; and a control module of the electronic control unit connected to said magnetic-field-sensitive sensor and to a discharge unit, said magnetic-field-sensitive sensor being connected to said loop circuit to cause said control module to activate said discharge unit for the shock-proof discharging of an energy accumulator in dependence on the sensor signal generated by said sensor when the contact connection is released.
