Supplier technologies could deep-freeze the steering wheel
A driver's finger movements engage
with a mouse-like device to steer a demonstration
vehicle. Eleven stereo cameras
on another demonstrator enable
detection and prediction of the distance
from vehicles navigating a roundabout.
" When we develop technology, our
vision is to have everyone in society
benefit from the innovation, " said
Harsha Badarinarayan, Hitachi Astemo's
vice president of advanced engineering.
Badarinarayan spoke with SAE Media
during a June press briefing at the company's
headquarters for the Americas in
Farmington Hills, Michigan.
Hitachi Astemo's in-development
steer-by-wire system's palm-size device,
located on a demo vehicle's center
floor console, responds to finger glide
movements with virtually no lag time
from input to the front wheels' response.
" The idea is to make this input
device, which especially caters to people
who need an alternative steering
interface, as intuitive to use as a steering
wheel, " said Badarinarayan.
SAE Media test drove Hitachi
Astemo's steer-by-wire system on a
Honda Civic with a steering wheel and
another Civic sedan equipped with the
finger-operated device. Both technology
demonstration cars were easy-tosteer
through a parking lot dotted with
orange cones to replicate slalom curves,
a tight U-turn, and a three-point Y-turn.
In another demonstration vehicle,
360-degree object recognition and
" This is a vision-only
system, so it doesn't
use lidar or other
sensors, " Hitachi
Astemo's Harsha
Badarinarayan said
about the company's
360-degree stereo
vision camera
system.
