A high-voltage motor vehicle electric system contains a high-voltage battery and a consumer network which are interconnected by an electric cable, and a quick-break switch for disconnecting the high-voltage battery from the consumer network. The quick-break switch receives an airbag signal. The airbag signal is used for actuating the quick-break switch to sever the electric cable supplying power to the consumer network.

The present invention relates to a work machine, in particular to a construction machine and/or mining machine such as a crawler-type vehicle, a dump truck, mining device or the like, having an electric drive which comprises power electronics which have at least one transformer which has power connections covered by a cover for connecting power cables, wherein a manually actuable grounding device is provided for the all-pole grounding of the transformer and/or for short-circuiting an intermediate circuit connected thereto. The invention in this respect in particular also relates to such a transformer. In accordance with the invention, the manually actuable grounding device is coupled to a cover latch of the cover such that the cover can be unlatched by actuating the named grounding device.

A vehicle includes: at least one rotary electric machine; an inverter that drives the rotary electric machine; a capacitor connected between a paired electric power lines that is connected to the inverter; and a control unit. When a vehicle collision is detected, the control unit executes first control for discharging electric charges stored in the capacitor by performing a switching operation of the inverter so as to prevent a flow of a q-axis current but cause a flow of a d-axis current to the rotary electric machine. The control unit stops the first control in a specified case and executes second control for performing the switching operation of the inverter so as to reduce the current flowing through the rotary electric machine to be lower than that during execution of the first control. The control unit executes third control for shutting down the inverter after execution of the second control.

The present disclosure discloses an automatic correction device for erroneous acceleration of an automobile, which includes an accelerator pedal, a robotic arm, and an acceleration sensor. The acceleration sensor is connected to a central control computer of the automobile. An error correction control box is arranged on a front cab baffle in front of the robotic arm. An elastic damper having a signal switch is arranged on a side wall of the error correction control box directly facing the robotic arm. The accelerator pedal enables the robotic arm abuts against the elastic damper. When excessive depression is applied, the elastic damper is compressed and deformed by the robotic arm and triggers the signal switch. After the signal switch is triggered, a clear warning sound or a humming sound is sent to prompt a driver to stop the excessive depression.
