The essential structure and principle of AELP (an active electronic license plate) invented recently is introduced. The technology provides a way of swift detection of any illegal change of the license plate of any vehicle-in motion or in parking. It can automatically provide on a screen such information about a detected vehicle as its registered license number, model, color, etc. Use of AELP will be an efficient means of high technology to guarantee good management of vehicle, traffic as well as public security.

The optimal control laws of 4WS during single lane-change are studied using the driver model of the preview follower method based on a certain vehicle model. The actual vehicle models are considered as uncertain systems. The cornering stiffness of the front and rear wheels and outer disturbance vary over a limited range. An adaptative model-following variable structure control method is used for controlling the steering of front and rear wheels of the actual vehicle, so that the steering characteristics of an uncertain vehicle model can follow the characteristics of a reference model. Simulation results have demonstrated that the control system can overcome the drawbacks of parameter perturbations and outer disturbances.

In designing a state observer for the suspension applications, the suitable selection of measurement signals is one of the important issues to achieve good estimation accuracy and meanwhile to ensure the system stability and also with the minimum sensor requirements. This paper investigates the estimation accuracy along with the robustness performance of a Kalman filter active vehicle suspension system and five different combinations of the measured states were compared. Simulations show the results of practical significance which will be useful for Kalman filter design in active vehicle suspension system.

At present, vehicle harnesses are composed according to a single function. As various electronic devices are applied in vehicles more and more, the power wiring and central signal wiring increase day by day. It is an inexorable developing trend that vehicle harnesses are more network-based and more intelligent. If one can use the concept of an electric power network on a vehicle, this will not only save money, but will also increase its utility. This concept can be used in various vehicles, and makes power harnesses more rational, economic and reliable. A next-generation intelligent harness system can consist of actual and imaginary nodes made up by signals which come from transducers, control components, ECU units and can operate in coordination with communication. It can realize integral optimization, centralized control and self-diagnosis.

In this paper, the configuration of a parallel hybrid vehicle is introduced. Several operation modes of the engine and electric motor and different control strategies are analyzed. The results show that, with proper control strategies and selection of the drive-train parameters, the vehicle can satisfy the urban and highway driving with a small internal combustion engine, a small battery pack and a single gear transmission. Moreover, the vehicle does not need to charge the battery from the electricity network for keeping its battery SOC at a reasonable level.

A regression formula has been developed for dividing the surface image obtained from an engine cylinder wall. By applying the formula, segmentation error can be minimized. The error, which results from the separation of the cylinder wall image, will lead to a potential loss of precision when the surface images of the cylinder wall are processed. By using the segmental image processing method, the experimental results show that the formula is correct and the technique is reliable.

In the application of an industrial robot, it is often found that the workspace is restructured or changed from time to time, as with for example mining robots or some construction robots. In some special cases, where for example there is dust or insufficient illumination in the environment, the use of sensors is limited. Ultrasonic sensors have been widely used in the robot application for its simplicity and low cost. However, determining accurate distance and direction of the obstacle from ultrasonic sensors is quite difficult due to the expanding beam of the ultrasonic waves. The uncertainty about the distance and direction information limits the further application of ultrasonic sensors. In order to use ultrasonic sensors efficiently, a blackboard strategy for multiple ultrasonic sensors is developed in this paper. Based on the blackboard, information of the inner sensors of robot and information from ultrasonic sensors are integrated and fused at the data-level, character level and decision level. Finally, a simulation shows that the uncertainty of the distance and direction information has been eliminated to some degree and a more accurate workspace has been obtained.

Vehicle dynamics are influenced by various nonlinear factors, such as tire characteristics, road conditions, etc. Hence, it is difficult to represent the vehicle dynamics by means of a two-degrees-of-freedom linear model perfectly. This paper presents a new four-wheel-steering (4WS) control system with a neural network that has the abilities of nonlinear modeling and control. A vehicle model of the RBF network is identified from the vehicle dynamics firstly. Next, the authors design a radial basis function (RBF) network controller with this vehicle model of the RBF network. The effectiveness of the proposed method is demonstrated with computer simulations.

For pt.III see ibid., p.485-90 (1999). This paper presents a new method for outdoor navigation and autonomous loading. The system consists of an autonomous vehicle and signs. Signs indicating waypoints and next instructions are tracked and recognized one after another by using a vision system. Once the vehicle recognizes a "loading sign", the environmental map is generated from range data obtained by an area laser radar and is processed to make a local path to the pallet which satisfies kinematics constraints of a car-like 4 wheeled vehicle. The system is adaptable to the changeable environment because transportation paths can be easily changed by altering the contents or placement of the signs. Experimental results obtained in the outdoor environment show the validity and flexibility of the system.
