Car dashboards have become a bewildering array of screens, buttons and knobs to control functions like the radio, ventilation, advanced safety systems and Internet services.
Looking to simplify such cockpitlike controls, automakers are starting to take design cues from a familiar household gadget, the tablet computer.

Ford, for example, announced last month that it would adopt a new touch-screen, tablet-like system to replace its much-criticised connected-car designs. “We looked at what aspects of tablets made sense,” said Don Butler, Ford’s executive director for connected vehicles and services, referring to the Sync 3, the next generation of the company’s in-dash system, which will appear in models this year. Ford plans to offer Sync 3 across its entire line in the United States by the end of 2016.

It’s a marked shift for Ford, whose sevenyear partnership with Microsoft produced several systems that were often criticised for being too complex and balky. The new system will be based on software from QNX Software Systems, a Canadian company with extensive experience in the automotive sector. Even though QNX is owned by BlackBerry, Ford took its inspiration for Sync 3 not from the parent company’s smartphones, but from Apple’s iPad.

Based on an 8-inch touch screen, Sync 3 uses fewer and larger icons that can be recognised at a glance. The touch-sensitive areas are bigger, and drivers can use more than one finger at a time, allowing for gestures like pinching to zoom in on a map. A bar along the bottom of the screen always displays primary functions like climate control, navigation and audio. But moves that may be convenient for a tablet user lying on a couch can be deadly for drivers.

Tesla Model S owners, for example, can view a reverse camera angle of the car while driving forward, as well as view other information, all of it illuminated on a vast 17-inch touch screen. “But the bigger size is better because it means the buttons can be larger,” said Todd Lockwood, a Model S owner in South Burlington, Vermont. Lockwood said he could adjust braking and suspension settings while driving, which is easier on the big screen.

Conversely, Cadillac has been criticised for its iPad-like CUE system, which has a touch-sensitive slider to adjust the volume. Ford endured similar disdain from many drivers over a touch-sensitive volume button in some MyLincoln Touch systems. To Ford, the message was clear: The volume knob stays. Butler said that Ford was sensitive to the problem of driver distraction. So some common gestures common in tablets and smartphones are not migrating to the dashboard.

“When you scroll through a list, the list continues to roll normally on a tablet, but that inertial spinning is not ideal for a vehicle environment,” Butler said. That move will not be in Sync 3 so that drivers do not become mesmerised spinning playlists, for example.

Ford said that it was keeping an eye on voluntary guidelines set in 2013 by the National Highway Traffic Safety Administration, which recommend that any single interaction not take more than two seconds. In that time, a car can travel 176 feet at 60 mph.

One of the most anticipated new touchscreen systems is coming from Volvo, which has made safety one of its biggest selling points. The centre piece of its new XC90 sport utility vehicle, coming early this year, is a new connected-car system that has a 9-inch touch screen.

“Everybody’s used to touch screens,” said Thomas Muller, Volvo’s vice president for electrical and electronic systems engineering. “You see them in modern kitchens; simple laptops come with a touch screen. It’s become mainstream and a normal thing to do.” As a result, there will be only eight buttons in the Volvo system, including what the industry calls hard controls for front and rear defrost, skip track, pause and a mandatory hazard warning light switch.

And, yes, there is a large knob that can control the volume. Muller argues that because consumers are so accustomed to touch interfaces, it’s the safest design for connected-car systems, with some caveats. “Interactions on the screen should not lead to misinterpretation,” he said, “because while driving it can be devastating.”

Not all automakers are embracing touch screens, including Audi. Anupam Malhotra, Audi’s senior manager for connected vehicles, said that rather than using a single iPad-like screen, multiple touch screens might be a better solution. (Audi is about to introduce its next-generation connected-car system, but would not say whether it will adopt a touch screen.)

Nevertheless, many automakers are clearly on a tablet track. What’s less clear is how they will work with the companies behind those tablets. Nearly every car manufacturer insists it is working closely with Apple and Google, each of which will be promoting their own software CarPlay and Android Auto this year. While that happens, the tablet revolution rolls on.
