A hybrid vehicle includes: an engine; a motor; a drive system battery connected to a drive system power line; an auxiliary system battery connected to an auxiliary system power line; a bidirectional power converter configured to step down power on the drive system power line to supply the stepped-down power to the auxiliary system power line, and configured to boost power on the auxiliary system power line to supply the boosted power to the drive system power line; and a control device. The control device is configured to, upon a cold start in which the engine is started, control the engine, the motor, and the bidirectional power converter to cause the motor to crank the engine while causing the bidirectional power converter to boost the power on the auxiliary system power line to supply the boosted power to the drive system power line.

Aspects of the invention are directed towards a system and method for safe decoupling of the external power supply from a vehicle. The technology described herein provides an indication or an alert to the user at an appropriate time and avoids the possible damage to the system. The system comprises an electrical port by which the refrigerator can be connected to an external AC mains supply via an electrical cable when the vehicle is in stationary state. The system further comprises a refrigerator main controller unit (RMU) for controlling the power delivered to the refrigerator in both stationary and driving states of the vehicle. There is a safety system installed for restricting the vehicle from being driven when the electrical port of the system is connected to the AC mains supply via the electrical cable and the refrigerator is powered by the AC mains supply.

A high voltage traction system for a vehicle includes two independently controllable power sub-systems being a powertrain power sub-system, PPS, and a vehicle power sub-system, VPS. The PPS comprising a plurality of PPS secondary power consumers and a PPS master controller being configured to arbitrate power limits among the PPS secondary power consumers by a first arbitration logic, and the VPS comprising a plurality of VPS secondary power consumers and a VPS master controller being configured to arbitrate power limits among the VPS secondary power consumers by a second arbitration logic, different to the first arbitration logic. A master interface is between the PPS master controller and the VPS master controller enabling communication exchange between the PPS and VPS including system-shared instructions of prioritization of the PPS and VPS secondary power consumers limiting the first arbitration logic and/or the second arbitration logic in a limited state.

An accessory control system for a vehicle includes a controller configured to be installed on the vehicle and a wire harness connected to the controller to communicate output signals from the controller. The wire harness has an input connector and an output connector. The input connector is connected to the controller. The output connector is configured to be selectively connected to one of a first vehicle accessory and a second vehicle accessory. The output connector of the wire harness is configured to be disposed at a selected location on the vehicle. The controller is preprogrammed to transmit at least one first accessory signal through the wire harness to control the first vehicle accessory. The controller is configured to be reprogrammed to transmit at least one second accessory signal through the wire harness to control the second vehicle accessory.

To provide stopping assistance, the disclosure relates to a method for operating a motor vehicle, in which a stopping point for the motor vehicle is determined using a sensor device of the motor vehicle. In the method, the motor vehicle determines a need to stop at the stopping point and initiates stopping of the motor vehicle at the stopping point when the need is present. If the need is absent, a control device of the motor vehicle performs a movement of the motor vehicle or issues a message characterizing the absence of the need to a driver of the motor vehicle. The disclosure further relates to a motor vehicle.
