Highly reliable contactless magnetic position sensing technology from
ams AG (SIX: AMS), a leading provider of high performance analog ICs and
sensors, has gained valuable endorsement from the demanding automotive
industry.
International automotive supplier Continental is basing its new CPS
series chassis height sensor on the AS5162, a magnetic position sensor
from ams.
The AS5162, paired with a simple two-pole magnet, accurately detects
angular displacements as fine as 0.09° over a full revolution. Its
non-contacting semiconductor technology is immune to stray magnetic
fields and, unlike optical or contacting position sensors, it is
unaffected by contaminants such as oil, grease or dirt.
The CPS series is used in the latest active chassis control systems to
measure the height of a vehicle’s chassis relative to its wheels.
Permitting a flexible range of configurations, the AS5162 can also be
used in additional position sensing applications such as headlight range
and level controls, and for other angle measurements, for example in
commercial vehicles such as dump trucks.
In a safety-critical system such as active chassis control, the CPS
series is required to comply with the ISO26262 functional safety
standard. This standard requires vehicle manufacturers to achieve high
levels of reliability, to analyze the effects of the failure modes of
components and systems, and to take measures to guarantee functional
safety in the event of a predictable failure.
An AEC-Q100 qualified device, the AS5162 underpins Continental’s
achievement of ISO26262 compliance for its CPS series product because of
its extremely low FIT (Failure In Time) rate – a key measure of
reliability defined by the standard. The wafer fabrication processes of
ams also provide for precise analysis of the device’s failure modes.
‘Advanced active chassis control systems call for very precise, accurate
and fast measurement of the movement of the chassis. This is a perfect
application for the AS5162, a high-sensitivity, low-noise position
sensor,’ said Bernd Gessner, vice-president and general manager of the
automotive business unit at ams. ‘And ams provides fully traceable data
to support automotive manufacturers’ functional safety design practices,
helping to minimize the effort required to comply with ISO26262.’
