A motor driving control apparatus in the embodiment includes: a first controller configured to control powering and regeneration of a motor; a second controller configured to control the first controller; and assistant circuitry configured to activate the second controller in a stop state, when a counter electromotive force caused by the motor, which is rotated without control by the first controller, satisfies a predetermined condition, before a power-on instruction for the motor driving control apparatus is made or in a state where the power-on instruction for the motor driving control apparatus is not made.

A control device for a motor vehicle. In the event of an interruption of an external voltage supply, limited functionality can continue to be maintained. For this purpose, it is provided to deactivate some functional modules of the control device in the event of an interruption of the external supply voltage and to use electrical energy stored in the deactivated functional modules for the voltage supply of further functional modules.

A power supply system for safety-relevant systems in a motor vehicle is provided that includes a first supply path and a second supply path. The first supply path includes a first connection point for a first voltage source, one or more first supply points for a safety-relevant load, and a first fuse between the first connection point and the first supply point. The second supply path is electrically coupled to the first supply path and includes a second connection point for a second voltage source, one or more second supply points for the safety-relevant load, and an electronic second fuse coupled between the second connection point and the second supply point. The safety-relevant load is capable of being electrically coupled to both the first and second supply point. Disconnecting elements are provided to isolate a fault in conformity with ASIL B.

A vehicle includes an electric machine, a coolant circuit, a refrigerant circuit, and a controller. The electric machine is configured to charge a battery via regenerative braking. The coolant circuit has an electric heater. The refrigerant circuit has an electric compressor. The controller is programmed to, responsive to a capacity of the battery to receive power being less available regenerative braking power and ambient air temperature being less than a first threshold, direct regenerative braking power to the heater but not the compressor. The controller is further programmed to, responsive to the capacity of the battery to receive power being less available regenerative braking power and ambient air temperature exceeding a second threshold that is greater than the first threshold, direct regenerative braking power to the compressor but not the heater.

Systems are disclosed for providing a work vehicle with a second air conditioning compressor driven by a small engine mounted on the work vehicle. The second compressor shares a refrigeration loop with the primary air conditioning compressor of the work vehicle. The small engine may be configured to drive various loads, and accordingly may include control circuitry to manage the power provided to the various loads, including the second compressor.
