A vehicular vision system includes a sensor disposed at a vehicle and having a field of sensing exterior of the vehicle. The sensor captures sensor data. Electronic circuitry of an electronic control unit (ECU) includes a processor for processing sensor data captured by the sensor. Responsive to the vehicle being parked, captured sensor data is processed at the ECU to determine a topography of the environment at the parked vehicle. The ECU, responsive to determining the topography at the parked vehicle determines presence of a hazard of the topography. The ECU, responsive to determining presence of the hazard, notifies an occupant of the vehicle of the hazard prior to the occupant exiting the parked vehicle.

A leakage protection system for a heating, ventilation, and air condition (HVAC) system can comprise: a power source; a louvered assembly including a frame, slats spaced apart vertically within the frame and extending from a first side to a second side of the frame, an actuator rod operably coupled to the slats, and a spring; a solenoid operably coupled to the actuator rod; and a first pressure switch disposed electrically between the power source and the solenoid.

A vehicular cabin monitoring system includes a carbon dioxide sensing device disposed at a vehicular component of a vehicle. The carbon dioxide sensing device captures sensor data representative of a sample of air at the vehicular component. The cabin monitoring system, based on processing at an ECU of sensor data captured by the carbon dioxide sensing device, determines a carbon dioxide level at the interior portion of the vehicle. The cabin monitoring system, when the vehicle is parked and not operating and based on the determined carbon dioxide level at the interior portion of the vehicle, determines occupancy of the vehicle. The cabin monitoring system, when the vehicle is operating and based on the determined carbon dioxide level at the interior portion of the vehicle, controls a heating, ventilation, and air conditioning (HVAC) system of the vehicle.

A heat pump system for a vehicle comprises a heating, ventilating, and air conditioning module as well as a refrigerant circuit including a compressor, an internal condenser, and an external condenser. The module comprises a warm air path including the internal condenser, a cold air path formed independently from the warm air path, a purge flow path branching from the warm air path at a position downstream of the internal condenser with respect to a flow of air through the module, and a purge control door adjustable between a first position preventing fluid communication between the warm air path and the purge flow path and a second position allowing fluid communication between the warm air path and the purge flow path. The purge flow path provides fluid communication between the warm air path and the ambient environment.

Provided is an air conditioning apparatus that is capable of suppressing increases in volume and cost of the apparatus and performing more suitable overheating protection. An electric compressor is an inverter-integrated electric compressor (10) integrally including a compressor (5), an electric motor (6) that drives the compressor (5), and an inverter (7) including a temperature sensor (11) that detects the temperature in the vicinity of a semiconductor switching device, wherein a controller (3) estimates a discharge temperature of the compressor (5) on the basis of a correlation of respective pressure loading characteristics for the detected temperature of the inverter (7), for the rotational speed of the compressor (5), and for the motive force of the compressor (5) in a refrigerating cycle (2).

A vehicle air-conditioning system capable of reducing energy consumed during traveling while preventing a significant uncomfortable feeling of a user. An inside-vehicle environment predicting unit calculates, by using inside-vehicle sensor information and outside-vehicle sensor information being output from an environmental sensor device and a predicted travel time acquired by a predicted travel information acquisition unit, at least one predicted environmental characteristic which is an environmental characteristic inside a vehicle after a predicted travel time on an assumption that an air-conditioning device is operated in each of at least one candidate mode which has lower intensity than intensity of a selection mode among a plurality of operation modes. A mode controller resets the selection mode to one of the at least one candidate mode, in which the predicted environmental characteristic being within the allowable range is calculated by the inside-vehicle environment predicting unit.

A method for estimating thermal sensation calculates, on the basis of a thermal image, a first temperature, which is a surface temperature of a first area, and a second temperature, which is a surface temperature of a second area, calculates a first amount of heat lost on the basis of the first temperature and first information, calculating a second amount of heat lost on the basis of the second temperature and second information, obtains an area ratio of the first area to the second area, calculates a total amount of heat lost, which is an amount of heat lost from a whole body of a person in a unit area, on the basis of the first amount of heat lost, the second amount of heat lost, and the area ratio, and estimates thermal sensation, which indicates a degree of warmth or coldness of the person, on the basis of the total amount of heat lost.

A method for controlling a thermal comfort control system for ride share vehicles includes providing a plurality of occupant seats in a vehicle cabin and controlling a cabin set temperature using a cabin comfort control system configured to adjust a plurality of HVAC functions. At least one thermal comfort parameter is adjusted at a number of the plurality of occupant seats using at least one seat comfort control system. Adjusting the at least one thermal comfort parameter causes the cabin control module to adjust the set temperature of the vehicle cabin.

An apparatus and coolant pump for use in a thermal management system includes a pump housing having an inlet for receiving coolant from the thermal management system and at least first and second outlets extending from the pump housing for directing coolant to at least a first and a second coolant loop. An impeller coupled to an electrical pump motor drives the coolant from the inlet to the first or the second outlet. A valve mounted between the impeller and the first and second outlets selectively directs the flow of coolant through the first or the second outlet. A temperature sensor installed on the pump housing inlet measures the temperature of the coolant entering the coolant pump.

In one embodiment, a vehicle defogging system may include a side mirror defogger, one or more other vehicle defoggers, one or more sensors, and a control unit. The side mirror defogger is independently controllable from the one or more other vehicle defoggers. The one or more sensors are configured to output a signal indicative a substance on a side mirror of a vehicle. The control unit is configured to detect the substance on the side mirror based on the signal of the one or more sensors, and activate the side mirror defogger in response to detecting the substance on the side mirror.
