20-in. automotive touchscreens enabled by new controllers

With cars like the Tesla Model S featuring 17-in. touchscreens, the trend in automotive displays is to go bigger and bigger. But unlike handheld mobile devices, screens in automobiles need to meet stringent head impact and vibration tests, so they have thicker cover lenses that potentially affect the touch interface performance. As screens get larger, they are also more likely to interfere with other frequencies and car access systems. These factors pose a major challenge in the design of modern automotive capacitive touch systems, but a new family of single-chip maXTouch touchscreen controllers from Microchip Technology was designed to address these issues.

Check the back seat: Rear Door Alert technology to become standard on all four-door Nissan nameplates

Nissan is making Rear Door Alert* (RDA) technology standard on more models to remind customers to check the back seat and help reduce potential heatstroke incidents.

Originally developed by two mothers who are also engineers, Rear Door Alert reminds owners to check the rear seat upon exiting their vehicle by using a series of distinctive honks as the driver walks away from the vehicle. Nissan is the first automaker to use a honking horn as an alert for this type of feature.

"What started as a chat with my colleague, Elsa Foley, is now innovative technology being adopted in more Nissan models," said Marlene Mendoza, a mechanical engineer who helped create the technology.

After Mendoza and Foley presented the idea, the project moved into full development at Nissan Technical Center North America (NTCNA) in Farmington Hills, MI.

"The idea was inspired when I accidentally left a pan of lasagna in the back seat of my car overnight," said Mendoza, a mother of three, who was pregnant when the idea struck. "The worst thing was the car smelled for days, but it made me ask myself, 'What if I left something far more important back there?'"

The temperature inside a vehicle can increase to dangerous levels quickly, according to the National Highway Traffic Safety Administration (NHTSA). Even with moderate outside temperatures in the mid-60s, a vehicle's interior can quickly heat up to more than 110 F.

How Rear Door Alert works
RDA, which currently is standard equipment on the 2018 Nissan Pathfinder, monitors when the rear door is opened and closed before and after the vehicle is in motion. The system responds with a series of notifications if a rear door was used prior to a trip, but was not re-opened after the trip. Once the vehicle is in park and the ignition is turned off, the system will first display a notification in the instrument panel and progresses to subtle, distinctive chirps of the horn.

The RDA system is easy to configure and can be temporarily, or permanently, turned off through a menu in the cluster display.

"If you open a rear door and put something in the rear seat, Rear Door Alert will help you remember when you get to your destination that you may have forgotten it," Mendoza said. "By drawing attention back to the vehicle while the driver is walking away, the honking alerts you to recheck the back seat in addition to visual or interior audible alerts."

Mendoza (listed as Henry on the patent) and Foley are the inventors on U.S. Patent No. 9,734,695 for the "activity monitoring apparatus," otherwise known as Rear Door Alert. This is the first patent granted to either Mendoza or Foley.

* Rear Door Alert is only intended to remind people to check the rear seats of their vehicle under certain circumstances. It cannot prevent accidents caused by inattention or carelessness.
