A control device for controlling a vehicle provided with a power supply function for a user includes a control unit that causes a light of the vehicle to blink under a certain condition when a power outage is detected.

Described herein are wireless nodes (e.g., communication and lighting systems) that are positioned in an elevated position above a cab for agricultural operations or can be positioned as a stand alone node. In one embodiment, a communication and lighting system is positioned in an elevated position above the cab. The communication and lighting system includes antenna elements and a dual frequency radio to transmit and receive communications.

A road vehicle that has: a passenger compartment delimited by a roof at the top; at least one front seat arranged in the passenger compartment; and a manual control arranged on the roof for the activation of hazard warning flashers.

An embodiment relates to a system, comprising: a sensor; a communication module; and a processor; wherein the processor is configured to detect that a passenger of a vehicle is experiencing a medical emergency; generate of an alert signal on an infotainment system of the vehicle; turn on automatically an emergency indication light; generate of a path from the current location of the vehicle to a target location; maneuver the vehicle along the path to the target location; identify a medical facility based upon a location of the vehicle; contact an emergency service and provide the location of the vehicle and a health condition of the passenger of the vehicle; and transmit a medical record of the passenger of the vehicle to the medical facility. According to an embodiment, the system is configured to be a component of the vehicle.

A computer-implemented method for warning road users of a hazardous operating condition of a heavy-duty vehicle. The method comprises obtaining, by a processor device of a computer system, a speed limit interval associated with a road on which a heavy-duty vehicle is travelling, and wherein the speed limit interval is based on a speed limit of the road; determining, by the processor device, that a travelling speed of the heavy-duty vehicle is outside the speed limit interval; determining, by the processor device, that a travelling angle of the heavy-duty vehicle and/or of the road on which the heavy-duty vehicle is travelling is outside a predetermined travelling angle range; and automatically controlling, by the processor device, the vehicle hazard lights of the heavy-duty vehicle based on the travelling speed and the travelling angle.

A safety warning sign, when not in use, is rolled and stored inside to case, and in the event of emergency, when a driver opens the trunk and then opens the case by pulling a cover with a finger while the case is attached and affixed to the edge of the trunk by means of a magnetic body of an attachment member connected to the case, the safety warning sign stored in the form of a roll inside the case is, simultaneously as the case is opened, automatically spread open by its own weight (gravity) and deployed, thus allowing the driver, even in the state of panic from an accident, to easily and rapidly install the car safety warning sign and quickly escape to safety.
