A vehicle controller includes a processor configured to determine whether there is fogging on a window of a vehicle or a sign of fogging thereof, based on a fogginess sensor signal indicating a physical index related to the degree of fogging of the window of the vehicle or operation of a vehicle-mounted device of the vehicle capable of defogging operation. The fogginess sensor signal is obtained by a fogginess sensor provided on the vehicle. The processor is further configured to change a driving control level applicable to the vehicle so as to increase or prevent decreasing the degree of a driver’s involvement in driving the vehicle, depending on the driving control level currently applied to the vehicle, upon determination that there is fogging on the window of the vehicle or a sign of fogging thereof.

There is provided a method comprising: determining an occupancy status of a first region of a vehicle; determining, based at least in part on the occupancy status, a first climate control setting for the first region; controlling a climate control system of the vehicle to adjust a climate of the first region according to the first climate control setting; determining that a second region of the vehicle is unoccupied, wherein the second region is fluidly connected to the first region; determining a second climate control setting, wherein the second climate control setting is based at least in part on the occupancy status of the first region and characteristic data associated with a predicted potential change in occupancy status for the second region; and controlling the climate control system to adjust a climate of the second region according to the second climate control setting.

The invention relates to a computer-implemented method of controlling the cabin climate in a vehicle travelling on a road. A requested temperature value of a desired temperature for at least one part of the cabin is detected. An allowable temperature deviation from the requested temperature value is determined. Topographic data representative of the topography of an upcoming road segment is acquired. A flow creating device of an air-conditioning system of the vehicle is controlled based on the acquired topographic data so as to maintain the temperature within the allowable deviation. The invention also relates to a computer program, to a computer readable medium, to a control unit and to a vehicle.

A vehicle includes a battery pack, an air conditioning system, a communication member, a pack humidity detector, an outside air humidity detector, and a controller. The battery pack contains a battery module. The air conditioning system is configured to regulate humidity of air and send the air. The communication member fluidly connects a blowing port of the air conditioning system and an inside of the battery pack. The pack humidity detector is configured to detect humidity in the inside of the battery pack. The outside air humidity detector is configured to detect humidity of an outside air. The controller is configured to control the air conditioning system so that the humidity in the battery pack is equal to or lower than the humidity of the outside air.

A method for controlling a rear glass defroster for a vehicle upon start-up is presented. First, one or more factors are determined, which are selected from a temperature of an environment immediately outside the vehicle, a humidity of the environment, a dew point of the environment, a barometric pressure of the environment, a temperature of a rear glass of the vehicle, a temperature of an internal cabin of the vehicle and a sun load on the vehicle. Next, the one or more factors are compared to one or more corresponding predetermined thresholds or ranges that are indicative of conditions suitable for frost formation on a rear glass of the vehicle. Then, if the comparison indicates that the one or more factors meet the frost formation conditions, the rear glass defroster is activated. A vehicle rear-glass defrost system which uses the foregoing method is also presented.

A control device is installed in the vehicle that is able to execute a fuel cut that stops fuel supply to an engine in a state in which the engine is rotating. In a case where there is a request for the fuel cut while there is a heating request in which heating of a vehicle cabin is performed using heat of an engine coolant, when a blowout port mode of air conditioning air is set to a defroster mode or a bi-level mode, the control device prohibits the fuel cut.

A vehicular air conditioner includes an air conditioning, a heater core, a heat pump cycle unit, a temperature detector, and a controller. The heat pump cycle unit includes a first inside heat exchanger disposed downstream of the heater core in a flow direction of a conditioning air, a second inside heat exchanger disposed upstream of the heater core in the flow direction of the conditioning air, and an outside heat exchanger. The temperature detector is configured to detect a passage air temperature, the passage air temperature being a temperature of the conditioning air that has passed through the heater core. The controller is configured to selectively switch a circuit layout of the heat pump cycle unit between a cooling circuit, a heating circuit, and a dehumidifying-heating circuit based on the passage air temperature.

There is provided with a moving body control apparatus. An image capturing unit captures a periphery of a moving body through a transmitting portion. A heater is capable of heating the transmitting portion. An air-conditioning unit switches an air-conditioning state in the moving body between an inside air circulation state and an outside air introduction state. A control unit controls the heater. An ambient temperature detection unit detects an ambient temperature. The control unit starts the operation of the heater when the ambient temperature is not more than a predetermined temperature threshold. The predetermined temperature threshold of the case in which the air-conditioning state is set to the inside air circulation state is higher than the predetermined temperature threshold in the case in which the air-conditioning state is set to the outside air introduction state.

A vehicle heating, ventilation, and air conditioning (HVAC) system including a cabin air filter, a sensor for providing a sensor reading, and a controller for determining a feedback signal from the sensor reading, wherein the controller determines a cabin air filter expected blockage level from the feedback signal. The feedback signal relates to a usage modifier of the cabin air filter, wherein the controller at east partially adjusts the estimated usage the cabin air filter from the usage modifier.

A method for autonomous climate control optimization of a transport vehicle having a climate control system is provided. The method includes a controller receiving geolocation specific data providing location information of the transport vehicle. The method also includes the controller receiving climate control data providing operational status information of the climate control system. The method also includes the controller receiving passenger/load data providing passenger/load information travelling in the transport vehicle. Also, the method includes the controller generating adjustment instructions of the climate control system based on the geolocation specific data, the climate control data, and the passenger/load data. Further, the method includes adjusting operation of the climate control system based on the adjustment instructions.
