A vehicle includes a plurality of lamps disposed on a rear portion of the vehicle, a user-actuatable hazard light control component (e.g. a turn-signal stalk) having a plurality of states, and a hazard lamp controller communicatively coupled to the plurality of lamps, the user-actuable hazard light control component, and the user-actuatable hazard light controller. The hazard lamp controller is configured to illuminate the plurality of lamps in accordance with a lighting pattern responsive to the state of the user-actuatable hazard light control component.

Systems and methods for vehicle hazard light control with selectable lighting patterns

Methods, systems are provided for controlling an auxiliary power outlet in a vehicle. The method includes connecting the battery powered device to the accessory power outlet, synchronizing communications between the battery powered device to a computing device of the vehicle, and determining when the battery powered device is connected to an electric bus and is charging. When the battery powered device is either not connected to the electric bus or the battery powered device is not charging, then disconnecting power from the accessory power outlet. The system includes a battery, an electrical bus electrically connected to the battery, at least one auxiliary power outlet in electrical communication with the battery and configured to mate with a battery charging port of a battery operated device; and an electronic control unit (ECU). The ECU is configured to disconnect power from the accessory power outlet when the battery is charged.

Systems and methods for auxiliary power outlet control

A system for controlling a lighting system for a vehicle includes an ambient light sensor operable for detecting a level of ambient light and a lighting circuitry. The system also includes a logical control unit that receives input signals from a vehicle control unit, a user input device and the ambient light sensor. The logical control unit controls a voltage on the lighting circuitry to provide a minimum voltage based on the one or more input signals.

Systems and methods for controlling vehicle lighting

A discharge system includes a battery, an electrical power bus selectively connected to the battery, a module configured to receive electrical energy from the battery via the electrical power bus, and a discharge resistor selectively connected to the electrical power bus. A contactor is operatively disposed between the battery and the electrical power bus. The contactor is configured to selectively connect the electrical power bus to the battery or the discharge resistor. That is, the contactor is configured to connect the electrical power bus to the discharge resistor in a default mode to discharge electrical energy stored in the module, and the contactor is configured to connect the electrical power bus to the battery in at least one vehicle operating mode.

Battery pack active discharge integration

A vehicle includes a high-voltage (HV) energy storage system (ESS), an HV power bus, a DC-DC power converter electrically connected to the HV power bus, an HV bus connector, a low voltage (LV) battery power bus, and a pair of LV bus connectors. The vehicle includes a vehicle module electrically connected to the HV and LV bus connectors, an LV power bus electrically connected to the DC-DC power converter and to the module, and a controller. The controller has an algorithm that controls the converter to power the module via one of the LV bus connectors during a transient LV condition. The converter and a method of controlling the same are also provided, with the method including determining the LV condition, powering the vehicle module via one of the LV bus connectors during the transient LV condition, and powering the module via the other LV connector otherwise.
