  • Collision severity determination system and method
    Patent number: 8725346
    Abstract: A system for vehicle safety enhancement is disclosed. The system comprises a sudden slowdown detection subsystem, a slight bump detection subsystem, an airbag activation and brake malfunction detection subsystem, and a rollover detection subsystem. A controlling unit is connected to each subsystem for determining a severity level of a collision involving a vehicle, and the controlling unit is in turn connected to a communication unit for sending an alert signal based on the severity level. A method for vehicle safety enhancement is also disclosed.
    Type: Grant
    Filed: December 8, 2011
    Date of Patent: May 13, 2014
    Assignee: Hong Kong Productivity Council
    Inventors: Yangsheng Xu, Guoqing Xu, Yongquan Chen, Huihuan Qian, Xin Shi, Ning Ding, Wing Kwong Chung, Yuandong Sun, Maxwell Chow
