Hi, I'm watching to make an inclinometer for motorcycle that show the inclination degree.
I've tried with a gyroscope but it can't be possible because of many forces that allow the bike to not fall into the bend.
I think it's possible to use some accelerometer positioned to some degree from each other.
Anyone have any ideas?
Thanks
p.s. I'm sorry for my bad english.
Accelerometers are used to measure tilt angles, as described here: http://www.freescale.com/files/sensors/doc/app_note/AN3461.pdf
However, when the motorcycle is accelerating (which includes traveling around a curve), the tilt readings will be incorrect.
My idea is to create an inclinometer test to see what are the problems to correct the reading error and remove forces that invalidate the reading.
Centrifugal force keeps the motorbike standing, it is why I can't use gyroscope. With accelerometers I would eliminate this force and calculate inclination degreee.
Thanks
Seems to me that a gyro would be the perfect sensor.
This idea comes up quite often, and is a very difficult one to solve. As you found out, the forces you want to measure are nearly always in line with the center of gravity and the tire contact on the road surface. Even an accelerometer will not measure the angle of a moving motor cycle.
