Today's vehicles are smart. They have the ability to prevent front and rear end collisions, park themselves, detect if you've drifted out of your lane, and even warn you if you're getting too tired to drive safely. Another smart system that your customers might tend to overlook is the vehicle's climate control. Unlike your home that typically uses only a single thermostat to control the temperature, vehicles employ numerous components to keep drivers comfortable. The climate control systems in today's vehicles use ambient air temperature sensors, interior temperature sensors. I will let duct and evaporator temperature sensors, pressure sensors, humidity sensors, infrared sensors to measure body temperature, blend door position sensors, and sun load sensors. More recent innovations include carbon dioxide sensors and sensors that will monitor the levels of pollution, shutting off air intakes when air pollutants are detected at certain levels. The first automatic temp systems offered only a one-zone climate control. Advanced technologies for controlling car climate introduce zone to climate control, allowing occupants to set their desired temperature to affect only their seats. Each area in the specific zones has a separate sensor that detects the current temperature of only that area. This system comes along with a computer that controls the air system within the zone by controlling the fan speed, air temperature, and air flow distribution. Now this led to further development with larger vehicles such as minibans and SUVs, which featured a third zone with its own temperature control. Backseat occupants now have their own air vents, and in some cases it's a lot of vents. For example, the Alexis LX-570 has 28 of them, as well as a temperature setting to play with. Some manufacturers provide an air-conditioned or cooled glove box as a convenience option. The cooled glove box uses the cool air generated by the car's air conditioner to cool water bottles and beverage cans. More technologies to keep drivers comfortable are on the way. Swiss manufacturers since Sierra on has developed technology that incorporates climate control into heated and cooled seats. Automatic climate control and vehicle seats continuously measure the humidity and temperature on the seat surface and backrest, automatically controlling seat heating and ventilation. Thanks to the integrated humidity and temperature sensors, manually switching the system on or off or even re-adjusting it becomes unnecessary. Hyundai has developed a couple new technologies as well. Hyundai's after-blow technology drives the condensate on the evaporator to suppress mold growth in the air conditioning system. The system has the after-blow tech activate for 10 minutes after the engine cools off to get rid of any leftover condensate. Then there's dog mode. Dog mode is a climate control feature that leaves the car's air conditioning or heater on when owners leave their pets in their Teslas. The temperature stays where the driver sets it for as long as they're away from the car. If the owner's gone for long periods of time and they shouldn't be, but if they are and the model threes battery goes below 20%, a push notification goes to the owner's phone to prompt them to get back to their pet. Maintaining the temperatures in the vehicle to keep all passengers comfortable is a high priority for vehicle manufacturers and these systems will only get more sophisticated in the future.
