A processing unit, method, and device for vehicle air conditioner warning are disclosed. The processing unit is configured to judge a ventilation state of the current vehicle location based on positioning satellite signals, to judge an operation state of the vehicle engine based on information, to judge a running state of the vehicle based on information received, to judge a using state of the air conditioner based on information, to judge a vehicle door/window opening/closing state based on information, and to determine that there is a potential risk of poisoning and initiate the warning element when all the following conditions are met: the ventilation state at the current vehicle location is bad, the engine is in operation, the vehicle is in a stopped state or runs at a low speed, the air conditioner is being used, and all the doors and windows of the vehicle are closed.

The method simultaneously manages climate control systems of a fleet of vehicles at a fleet server remote from the vehicles. The fleet server has one or more processors and memory storing one or more programs for execution by the processor(s). Initially, at least one parameter relaying information about performance of a climate control system of a respective vehicle is received, from each vehicle. Each vehicle's climate control system includes at least an electrically driven compressor. The system then determines whether a performance inefficiency exists for the climate control system of at least one vehicle based at least in part on the parameter(s) received from the at least one vehicle. Upon determining that a performance inefficiency exists, an efficient operational setting that reduces the performance inefficiency is determined. Finally, an operational setting instruction is transmitted to the at least one vehicle to control the climate control system of that vehicle.

A vehicle climate control system. An air conditioner and heater are operatively connected to a controller and control the temperature of the cabin area of a vehicle. A processor, operatively connected to the controller, determines the amount of time for an operator of the vehicle to travel between their location and the location of the vehicle. The processor determines an amount of time required to adjust the temperature of the cabin area of the vehicle to a selected temperature by using one of the air conditioner and the heater. The processor automatically operates one of the air conditioner and the heater to begin adjusting the temperature of the cabin area to the selected temperature when the amount of time required for the operator to travel between their location and the location of the vehicle is less than or equal to the amount of time required to adjust the temperature of the cabin area vehicle to the selected temperature.

Systems and methods are provided for estimating a quality of air in proximity to a vehicle. In one embodiment, a method includes: determining a radius of the vehicle; estimating a number of vehicles within the radius of the vehicle; estimating the quality of air based on the number of vehicles; and selectively generating a control signal to an air inlet valve based on the quality of air.

A computer-implemented method includes receiving, with a vehicle computing system, global position system (GPS) data associated with a vehicle, determining a solar position relative to the vehicle, receiving trip information associated with the vehicle, and executing one or more vehicle actuators based at least in part on the GPS data, the trip information and the solar position relative to the vehicle. Determining the solar position can include determining a sun glare period during a future time period based at least in part on the trip information associated with the vehicle. The vehicle computing system may display a warning indicative of the sun glare period, generate a window tint command that causes the window to tint and/or generate a vent control command that causes the vent to change one or more of an airflow temperature, and an airflow velocity.

An air pollution reacting system in a vehicle comprises at least one air pollution measuring device installed in a vehicle and configured to measure an air pollution level of ambient air; and an air pollution reacting device configured to take at least one action in response to an air pollution level determined by the air pollution measuring device.

A HVAC system for a vehicle that includes a propulsion system, a frame, a passenger compartment, and a door coupled to the frame. The HVAC system includes a refrigeration circuit that selectively controls the temperature of the passenger compartment based on a sensed temperature within the passenger compartment. The refrigeration circuit includes an exterior heat exchanger, a first air moving device coupled to the exterior heat exchanger, an interior heat exchanger, a second air moving device coupled to the interior heat exchanger, and a compressor. The HVAC system also includes a controller that is operable to detect a condition of the vehicle that includes at least one of a position of the door, a location of the vehicle, and a load of the propulsion system. The controller is programmed to adjust the refrigeration circuit in response to the sensed passenger compartment temperature and the detected vehicle condition.

A system for providing efficient climate control in a vehicle. The system has an HVAC system configured to receive a user-defined temperature. The HVAC system has a cabin temperature sensor. The system has a controller coupled to the HVAC system and coupleable to a mobile device. The controller is programmed to (i) receive an estimated travel time of the vehicle from the mobile device and (ii) modify output of the HVAC system based on the travel time being below a time threshold.

A vehicle air-conditioning system includes at least one chiller and one cold storage unit which is designed as a PCM storage system with phase change material. The refrigeration power required for air-conditioning and for charging the PCM storage system are provided by the chiller where the cold stored in the PCM storage system is supplied to the assemblies for air-conditioning the passenger compartment in selected operating states of the vehicle. A sufficiently large amount of cold can be conducted from a phase change material of the PCM storage system into the passenger compartment such that the chiller of the air conditioning system designed for cold generation is largely put out of operation and the discharge of larger amounts of heat from the rail vehicle into the tunnel is thereby avoided.

The disclosure generally pertains to systems and methods for using vehicles to detect and remediate air pollution. In an example implementation, a server computer transmits a directive to a vehicle controller of a vehicle, to measure an air pollution level around the vehicle at a first location. The vehicle controller executes an air pollution measurement and transmits measurement data to the server computer. The server computer evaluates the measurement data and directs the vehicle controller to perform a remedial action for reducing the air pollution level at the first location. The remedial action can involve, for example, the vehicle controller moving the vehicle from the first location to a second location. The server computer may also determine whether the first location is a transient pollution location or a persistent pollution by directing the vehicle controller to carry out measurements at two different times and/or by employing two different sampling rates.
