A vehicle and a method of immobilising a vehicle. The vehicle (100) includes a transport refrigeration unit (10), a power management system (20) for supplying power to the transport refrigeration unit (10), and a braking system (30). The power management system (20) includes an electric charging connector (26) and controller (24) configured to determine if a charging cable is engaged with the electric charging connector (26). If the controller (24) determines that a charging cable is engaged with the electric charging connector (26), the braking system (30) is configured to immobilise the vehicle (100).

A control system and method of controlling a utility vehicle. The system may include a controller, an energy mode input associated with a user input request to select one of at least two power modes, an implement control input associated with a user input request to select a movement of an implement, a drive control input associated with a user input request to select a movement of a drive system to propel the utility vehicle, and an attachment type input to further refine the allowed operating power states. The controller is adapted to determine a change between the plurality of operating power states in response to user input requests to automatically optimize machine performance and efficiency. Each of the plurality of operating power states includes a maximum electric current output and a maximum speed output of the electric motor.

Systems and methods for coordinating steering controls between towing vehicles and towed vehicles provide more cohesive parking experiences during towing events, including bidirectional charging towing events. The towed vehicle may be controlled to provide assistive parking steering maneuvers to assist the towing vehicle when parking during the towing event. The assistive parking steering maneuver may include maneuvering a drive wheel of the towed vehicle either toward or away from a detected curb or detected traffic, for example.

A wireless power feeding control apparatus for a vehicle includes a positioning unit and an examination unit. The vehicle is provided with a power receiving coil that wirelessly receives electrical power from a power transmitting coil of a power transmission facility, a parking lock mechanism, and a parking lock sensor that outputs an electrical signal corresponding to a locked state of a wheel established by the parking lock mechanism. The positioning unit positions the power transmitting coil or assists in positioning the power transmitting coil on the basis of a quantity of electricity generated by the power receiving coil receiving a magnetic field from the power transmitting coil subjected to weak excitation weaker than excitation during electrical power transmission. The examination unit checks the locked state of the wheel after the weak excitation is stopped and before the electrical power transmission is started.

A vehicle system is directed to providing a driver with a utility mode, which is an indoor environment condition of a vehicle where it may be rested, and includes: a vehicle communication portion that is configured to receive a first request message requesting execution of the utility mode by communicating with a service terminal provided in the vehicle or a driver terminal possessed by the driver; and a vehicle controller that is configured to set electric components and controllers involved in driving of the vehicle to an off mode when an entry condition for the execution of the utility mode is satisfied and the vehicle's starting is in an on-state, and sets an air conditioning device controlling an indoor air condition of the vehicle and a stack generating power required in the utility mode to a driving mode to execute the utility mode.

Methods, apparatus, systems, and articles of manufacture for vehicle turning in confined spaces are disclosed herein. An example apparatus disclosed herein instructions, at least one memory, a processor to execute the instructions to operate a first brake of a first wheel of a vehicle, operate a second brake of a second wheel of the vehicle, determine a frictional coefficient of a driving surface of the vehicle by rotating a third wheel of the vehicle, determine based on the frictional coefficient, if a turn command can be conducted by the vehicle, and when the turn command can be conducted, conduct the turn command.

A control system and method of controlling a utility vehicle. The system may include a controller, an energy mode input associated with a user input request to select one of at least two power modes, an implement control input associated with a user input request to select a movement of an implement, a drive control input associated with a user input request to select a movement of a drive system to propel the utility vehicle, and an attachment type input to further refine the allowed operating power states. The controller is adapted to determine a change between the plurality of operating power states in response to user input requests to automatically optimize machine performance and efficiency. Each of the plurality of operating power states includes a maximum electric current output and a maximum speed output of the electric motor.

A power supply device supplies power from a power transmission coil to a power reception coil of a vehicle in a non-contact manner. The power supply device has a communication unit that receives a startup signal for activating the power supply device. A notification unit notifies a state of the power supply device. A controller controls the notification unit based on a detection result of a detection unit. The detection unit detects a non-contact power supply possible state, in which power can be supplied from the power transmission coil in a non-contact manner. The controller sets a notification state of the notification unit to a first notification state, when the non-contact power supply possible state is detected, and sets the notification state of the notification unit to a state that is different from the first notification state, when the non-contact power supply possible state is not detected.

A vehicle emits a first signal when the vehicle moves after reception of electric power from an electric power transmission device by an electric power reception device is completed and when a preparatory condition for the vehicle to move is satisfied after reception of electric power from the electric power transmission device by the electric power reception device is completed. When a charging station receives the first signal, the charging station emits a second signal notifying that a state allows charging.
