Ford readies in-wheel steering tech

Ford has announced new variable-ratio steering technology it says improves steering response at slow speeds, thus making its easier to manoeuvre and park its cars.

Due to be rolled out within 12 months in the US, the new system is also claimed to make Ford vehicles "more agile and fun to drive" at higher speeds.

It's similar in concept to variable-ratio steering systems already offered by a wide range of luxury car-makers and goes a step beyond the now-common variable-assistance systems seen in both hydraulic and electric power steering systems.

However, it remains distinct from the more advanced 'active' and rear-wheel steering systems offered by some brands, including Porsche, BMW and Lexus.

Like other variable-ratio steering set-ups, Ford's Advanced Steering Technology progressively reduces the degree of steering wheel input required to turn the car at lower speeds.

That is, the number of steering wheel turns or revolutions required to reach full lock is less when the car is stationary or driving slowly, and more at higher speeds.

The technology reduces the effort and time required to perform low-speed manoeuvres such as a three-point turn or negotiating a tight shopping centre car park, without reducing stability at higher speeds.

The electronically controlled steering system constantly changes its ratio according to road speed. At freeway speeds it is less sensitive, making it easier to maintain a straight heading.

However, the difference with Ford's system, which was developed with Japanese supplier Takata, is that it uses a small electric motor and gear set located within the actual steering wheel to boost or retard steering inputs.

Because the system is contained in the steering wheel, it's likely it can be retrofitted to current models.

Ford is keeping tight-lipped about which vehicle will debut its adaptive steering tech – including in Australia -- but stated "select vehicles beginning next year" will benefit.

Raj Nair, Ford's Vice President for Global Product Development, said the new technology optimises steering response in all conditions and "can make any vehicle easier to manoeuvre and more fun to drive."

Nair's 'fun to drive' comment suggests we could see the new system deployed in performance cars, perhaps including Ford's new-generation Mustang, which arrives in Australia from the latter half of 2015.
