Analysis and Realization of Power Supply Switch with Motion Sensing Based on Tire-mounted Accelerometer of Automobile

In order to reduce the power consumption in the braking performance monitoring system of automo-bile, a new scheme of power supply switch is proposed with motion sensing based on tire-mounted accelerometer,analyze different location arrangements of accelerometer mounted on the tire and the shaping of output signals, as well as discussed the realization of power supply switch with motion sensing. The practical results show the achieve-ment of saving energy with motion sensing.
