It is possible to communicate and measure the distance between the user and targets, the relative speed, and the angle to multiple targets and to communicate with the multiple targets by the vehicular spread spectrum radar system. However, if multiple targets exist at different places with the same distance from the vehicle, it is difficult to separate the signals by identifying the targets. In this paper, we apply the algorithm of detecting different direction of arrivals (DOAs) of the reflected signal waves from the targets, which is based on the spatial spectral estimation capability of an array antenna. Performance of the proposed schemes is analyzed by computer simulations.","PeriodicalId":114981,"journal":{"name":"Proceedings of the IEEE Intelligent Vehicles Symposium 2000 (Cat.

The proposed sequence is a concatenated EOE sequence, which is composed of inner-sequences with EOE sequences and an outer sequence with an M sequence. We proposed EOE sequences that have equivalently good properties of both even and odd correlation, which are important for acquisition and demodulation in SS communications. Usually the concatenated sequences that PN-sequences are connected simply have bad properties of autocorrelation. Inner-sequences that composed the concatenated EOE sequence have good properties of correlation. Moreover the concatenated sequence has good properties of autocorrelation. This results in low peaks for autocorrelation of the concatenated EOE sequences, which is useful for achieving stable acquisition. And the proposal sequences have long period. So the concatenated EOE sequence is suitable for a spread spectrum communication and ranging system uniquely.","PeriodicalId":114981,"journal":{"name":"Proceedings of the IEEE Intelligent Vehicles Symposium 2000 (Cat.

Unfortunately, it has to pay a huge calculation cost and can not deal with some complicated motion pattern like overlapping of tracked objects. A new concept of tracking cycle is proposed in the paper. With the continuous estimation of moving objects vitality and reliability values, our method can detect and track up to more than 30 moving objects in real time. The flexible dynamic template matching method is also presented in the paper, which makes our system faster and more efficient for real-time ITS applications. Experiments on real outdoor road scenes show the accuracy and efficiency of our approach.","PeriodicalId":114981,"journal":{"name":"Proceedings of the IEEE Intelligent Vehicles Symposium 2000 (Cat.

We focus on using direct radio communication between moving vehicles on the road that requires no additional infrastructure. Thus, the vehicles need to organize access to the radio channel in a decentralized manner. We derive the medium access control from the standard IEEE 802.11. Also, the vehicles use omnidirectional antennas implying that a sender can transit to multiple hosts simultaneously. As an example, we study a road accident that is reported to nearby vehicles. Simulations show that the quality of the proposed protocol by measuring how many vehicles inside a zone-of-relevance are informed under various conditions.","PeriodicalId":114981,"journal":{"name":"Proceedings of the IEEE Intelligent Vehicles Symposium 2000 (Cat.

The detection and classification of passenger seat occupancy open up new ways to control the airbag firing. We present a stereo system designed for the observation of the cockpit scene in order to provide information about the passenger presence and location within the vehicle cockpit; from the stereo data, a cockpit occupancy map is generated. Several typical configurations of the passenger seat must be recognized (empty seat, adult presence, baby seat, ...). During an offline learning step, several cockpit images are recorded for each of these situations; for each one discriminant attributes are extracted. Then, the seat situation is recognized using a case-based classification method.","PeriodicalId":114981,"journal":{"name":"Proceedings of the IEEE Intelligent Vehicles Symposium 2000 (Cat.

In a conventional car today, drivers would still be required to manoeuvre the vehicle at night without any assistance by the system. The traffic moves at higher speeds along the highways and freeways at night. In this paper we attempt to provide optimal illumination in the event of different road and weather conditions by designing a fuzzy control for head light intensity of the vehicle. We propose a fuzzy control for light intensify control. The design, development and the effectiveness of the control is discussed.","PeriodicalId":114981,"journal":{"name":"Proceedings of the IEEE Intelligent Vehicles Symposium 2000 (Cat.

The scaled depth is used to compute the time to contact, which provides a measure of distance to the target, and also to improve the common depth maps obtained from point matches, which are a valuable input for the robot to avoid obstacles.","PeriodicalId":114981,"journal":{"name":"Proceedings of the IEEE Intelligent Vehicles Symposium 2000 (Cat.
