Systems and methods of controlling the ventilation of an electric vehicle comprising a power cell and a cabin vent. An operational mode of the electric vehicle is determined. An operational state of the power cell is determined. The closure of the cabin vent is controlled based on the operational mode of the electric vehicle and the operational state of the power cell.

In a vehicle seat air-conditioning device, at least a first inlet, a second inlet, and an outlet are provided in a seat, and at least a first ventilation path, a portion of a second ventilation path, a ventilation path selection switch, a blower, and a third ventilation path are provided inside of the seat. To lead air to the third ventilation path, the ventilation path selection switch has: a first mode in which the first ventilation path is connected to the third ventilation path; a second mode in which the second ventilation path is connected to the third ventilation path; and a third mode in which the first ventilation path and the second ventilation path are connected to the third ventilation path. A controller switches between the modes of the ventilation path selection switch by selecting one of the first mode, the second mode, or the third mode.

A motion sickness reduction system for vehicle occupants, includes an information collector configured to collect driving information of a vehicle or state information of an occupant of the vehicle, a predictor configured to predict a motion sickness state of the occupant based on the driving information or the state information, and a driving display configured to display the driving information to the occupant for recognizing the motion sickness state.

When the temperature of a device that is constituted by an electric component or an electronic component and that is arranged below a rear seat exceeds a predetermined value during air-conditioning operation in an internal-air circulation mode, an air-conditioning switching action by which a rear air-conditioning unit is switched from the internal-air circulation mode to an external-air introduction mode is performed, and thereby ventilation of the vehicle cabin is performed. Therefore, before the surrounding temperature of an occupant significantly rises due to heat generated by the device and the occupant feels uncomfortable, by restraining the surrounding temperature from rising through external-air introduction to avoid a situation in which occupant feels uncomfortable, it is possible to maintain comfortableness in the vehicle cabin.

An interior ventilation system for a motor vehicle includes an air measurement chamber, into which outdoor air of the motor vehicle can be fed via an outside air supply line and vehicle interior air of the motor vehicle can be fed via an inside air supply line, air quality sensors for measuring a harmful-substance content in air located in the air measurement chamber, and a measurement air control unit, which is designed to selectively supply outdoor air and/or vehicle interior air to the air measurement chamber. A motor vehicle includes such an interior ventilation system.

A method, system, and apparatus are provided for optimizing control of the rotational speed of a fan in a vehicle so as to reduce the aerodynamic drag of a vehicle in a given operating parameter, and accordingly, to improve fuel efficiency of operation of the vehicle. Certain exemplary embodiments include determining an optimized speed of rotation of a cooling fan of the vehicle for reducing overall fuel demand in given operating conditions, and controlling rotation speed of the fan at the optimized speed in order to minimize fueling demand of a prime mover of the vehicle.

A vehicle climate control assembly for modulating a temperature of a passenger compartment includes a solar panel, a battery, a heating and cooling unit, a temperature sensor, and a controller, all of which are mountable to a vehicle. The battery is operationally engaged to the solar panel, which is mountable to an exterior surface of the vehicle. The heating and cooling unit is in fluidic communication with the passenger compartment of the vehicle and is operationally engaged to the battery. The temperature sensor and the controller are mountable within the passenger compartment. The controller is operationally engaged to the solar panel, the battery, the heating and cooling unit, and the temperature sensor. The temperature sensor measures a temperature of the air in the passenger compartment, positioning the controller to selectively actuate the heating and cooling unit to modulate the temperature within the passenger compartment.

Examples of the present disclosure relate to techniques for headlamp heater control. In examples, a headlight assembly comprises a heater, which is used to prevent or remove condensation/precipitation on a lens of the headlamp assembly. Given it may be difficult for an individual to know when to manually turn the headlamp heater on, an electronic control unit (ECU) may evaluate a set of rules to determine when to automatically enable or disable the headlamp heater. The rules may be associated with atmospheric conditions outside the vehicle, the state of the vehicle (e.g., whether windshield wipers are turned on, whether windshield defog is enabled, whether a mirror heater is turned on, etc.), and/or user input received by an ECU of the vehicle, among other examples.
