Patent ID: 7990256

Claim:
An automatic warning and breaking system for a vehicle, comprising: a plurality of cameras for capturing images of objects inside and outside of the vehicle; a motion sensor unit comprising at least an acceleration sensor and a gyro sensor, configured for sensing motion of the vehicle, the acceleration sensor comprising a substrate, a mass and four resistors, the mass and the four resistors being arranged in a diaphragm on the substrate, at least two of the four resistors being piezoelectric resistors, and the four resistors being connected to each other to form a Wheatstone bridge; a data process unit, electrically connected to the cameras and the motion sensor unit, configured for processing data from the respective cameras and the motion sensor unit; an alarm unit, connected to the data process unit, configured for generating a warning signal for the driver of the vehicle if the data process unit detects unsafe driving conditions; a control unit configured for generating a control signal based on the warning signal; a break unit; and an adjustor unit, connected to the break unit, configured for applying an adjusting force on the break unit based on the control signal of the control unit.
