Advanced driver assist system using multi-sensor information fusion for co-operative driving

Electronics (Embedded system)

Active safety is an important trait of a modern vehicle to provide precaution warning or compensatory control before the pre-crash stage of vehicles safety. All vehicle signal and information are acquired by several in-vehicle sensors , and integrated in vehicle gateway through in-vehicle or vehicle-to-vehicle communications. The information exchanged among the host and surrounding vehicles provide comprehensive vehicle and driving status of each vehicle, so the driver can drive vehicle more safely with the cooperative driving mechanism. The demonstration system consists of a vehicle gateway, which is based on ARM core processor, PIC microcontroller, Bluetooth for I/O control and system management for intensive computation of information fusion and ZigBee for wireless communication. After reaching within the communication limit, the vehicles set time synchronization and then exchange vehicles information. Which consists of following phases path prediction and risk assessment. The risk assessment evaluates the possibility of car crash and transmit the warning message to its surrounding vehicles, if the risk level of vehicle is raised beyond a threshold. The cooperative driving is satisfied by sharing the vehicle information and emergency warning through wireless communication, so a driver can be alert of the dangerous situation and also be suggested an satisfactory response earlier.
