I want to find a pressure sensor driver on the steering wheel grip (preferably can be transferred to the steering wheel, internal) should use which kinds of sensors? How to design? Please understand people feel free, thank you! The answer is acceptable, I add points.
Can use PVDF piezoelectric film sensor, is a polymer material, can be made into any shape. You can contact manufacturers customized, commissioned by them to design
The driver's grip on the steering wheelIt's going to change. I think it's related to the degree of stress the driver hasIf you want to test, the driver will have an uncomfortable feelingIt may be difficultWhat do you want to know about this?
To tell you the truth, it's difficultThe reason is: if it is normal road grip on the steering wheel, so attention should be paid to staff, carrying on the steering wheel itself has a pressure, and some drivers turn with the palm of the hand pinch turn the wheel, not grip the steering wheel rotation; in addition, the driver is used to distinguish the two or holding one hand, because the two hands and a hand grip is certainly not the same, this should be considered a transient state.Therefore, the detection process is very complex, to be accurate measurement is even more difficult.The stress strain sensors on the first floor should be easy to install, but do not know how high the cost will be;If you put aside the driver's hand pressure, non normal driving factors, I have a method of making a silicon liquid filled by the steering wheel cover, set on the steering wheel, and then use the pressure pipe to the pressure to the pressure sensor mounted on the steering wheel shaft, the dynamic hydraulic transmission by human hands grip strength and pressure, and then converted to computer output or the corresponding processor are analyzed, finally the data might be what you want!That way, you don't have to change the steering wheel, just add a device. Also, the pressure felt by the liquid would be a relative average.I don't know what you're going to do with the data, but if there's any commercial value, the top cars like BMW and Mercedes should be available!
