Analysis of acceleration sensors in intelligent vehicle control application source

Triaxial accelerometer can measure the size of the smart car inertia , select the best center of gravity position , and can accurately locate the smart car in a straight line , curve , ramp, drift operational status ; using the acceleration sensor can predict in advance the path and determine when to brake the best results. And a good solution to balance the car models in the upright and direction identification . Thus presents a three-axis acceleration sensor in the smart car control and path identifica Crankshaft Position Sensor tion design. The design uses a three-axis acceleration sensor smart car in motion acceleration signals to the embedded chip as the core controller , the acceleration signal sampling , A / D conversion, and then the feature data stored in the EEPROM . Solves the smart car motion path analysis problems as well . Real-time access to the car acceleration, so a more comprehensive access to the car running, for the control of traffic fluency and better identification possible. Cars in the upright , the application of the same principle, to choose the best center of gravity , can solve the balance of car models as well as walking upright orientation recognition , thus speeding car models driving speed . Experimental results show that : Combining acceleration sensor has a strong anti-interference, to extract more accurate angle information to ensure that the smart car in a straight line to a higher speed, the curve is able to basically do not stall smooth cornering .
