This paper proposes a parking assist system that fuses around view monitor (AVM) image, ultrasonic sensor, and in-vehicle motion sensor. The proposed system recognizes various types of parking slot markings using AVM image sequences and classifies occupancies of the detected parking slots using ultrasonic sensors. Once a desirable parking slot is selected by a driver, its position is continuously tracked by fusing AVM images and motion sensor-based odometry. Experimental results show that the proposed system can reliably detect and track various types of parking slot markings.

Adaptive cruise control (ACC) systems, which detect distance of a preceding vehicle and a radar-mounted vehicle using the radar, are available from automobile manufacturers. The distance and a relative velocity of the preceding vehicle and the radar-mounted vehicle can be estimated by analyzing a millimeter-wave signal obtained through the radar. Due to a characteristic of the radar and the relative velocity between the preceding vehicle and the radar-mounted vehicle, it is difficult to detect and track the preceding vehicle in the same lane where the radar-mounted vehicle is moving. In this paper, an algorithm is proposed to solve the above difficulties. The proposed algorithm separates a radar-search range into several blocks. And it detects and tracks a preceding object as a detected block of the several blocks. Applying this algorithm and assigning priority among the blocks, the searching range for the targeting vehicle and response time of the system are reduced.

A new single-package curative for polyacrylate elastomer allows the fabricator to achieve short molding cycle, improved processability and the elimination of postcure by an injection molding process. The molded articles show good mechanical properties and excellent aging characteristics.
