According to a new report from IMS Research, automotive sensor technology will continue to evolve rapidly throughout the decade.
According to a new report from IMS Research, automotive sensor technology will continue to evolve rapidly throughout the decade.
Radar, ultrasonic and image sensors are just some of the new types of sensor that will increasingly be used in emerging automotive applications.
At the same time, new sensing techniques (such as giant magnetoresistance) are forecast to erode existing sensor technologies such as potentiometers owning to reasons of durability, packaging flexibility and cost.
Systems such as ACC, park/reverse assist and night vision all use advanced sensors like image, laser and ultrasonic sensors.
Fitment of these systems in light vehicles is forecast to increase rapidly throughout the decade.
At the same time, other systems such as lane departure warning and camera-based adaptive airbag are just around the corner.
Report analyst Jon Cropley commented: "Many of the high growth automotive systems are not only sensor dependent but also require high value sensors.
The result is rapid revenue growth forecast for the market".
Industry pressures are also forcing existing vehicle functions to employ new measurement techniques and for sensors to be manufactured using new methods.
For example, acceleration sensors based on MEMS (microelectromechanical systems) are now common.
MEMS-based gyroscopes are being developed and introduced and it is likely that MEMS technology will increasingly be used for other types of automotive sensor, such as pressure sensors.
At the same time, AMR (anisotropic magnetoresistive) sensors are being used to detect speed and position while sensors based on the GMR (giant magnetoresistive) effect are being developed.
"One thing is clear", stated Cropley "The composition of the automotive sensors market in 2010 will be revolutionary different to the automotive sensors market today".
