In order to use less lines to realize data communication between test devices, microprocessors, sensors and actuators and to accelerate the development of the computerization of vehicles, BOSCH developed a controller area network (CAN) in the early 1980s. Because of its many advantages, a CAN bus is to be adopted in electric equipment which is being researched at present or will be researched in the future. In a sense, the CAN bus begins a new era of electric equipment of vehicles. This paper introduces some advanced characteristics of CAN and makes a comparison between CAN and BITBUS presented by INTEL. The application of CAN on a vehicle is proved by three examples.

In this paper, the integrated powertrain control system is discussed which receives input and output speeds of the transmission, the engine speed, and the accelerator pedal position and uses this information to adjust engine torque and speed to effect a shift of the automatic transmission. The optimum model is given in this paper which has been tested. The automatic transmission loaded by an inertia flywheel and high-pressure pump, powered by diesel, and controlled by an electronic system, is the object of this test. The result shows an improvement of shift quality in most cases. The test proves that the integrated control can reduce the jerk.

This paper presents the software development on the performance simulation of electric vehicles. Software verification is carried out via the comparison of simulation results with on-road test. Applications of the software in prototype design are also presented in terms of theoretical inference, modeling, software development and simulation of synthetical performance for EVs such as dynamic performance, economy performance as well as analysis of parameters' influences on EV performance. The commonly used European drive cycle is adopted for simulation in the paper. Simulation with the software proves an efficient and money-saving means for prototyping of EV or HEV systems with control units.

This paper presents the path planning/control method of a car-like mobile robot. The proposed two-stage path planner consists of the global path planner and the local path planner. The global path planner finds collision-free paths from an environmental map, which features universal consideration of the topological configuration of all obstacles by the method of Maklink Graph. The local path planner/controller linearises the robot dynamics by using the chained form and accomplishes a closed-loop control. This satisfies the nonholonomic constraints and obtains robustness toward model errors, drift and disturbances. Obstacle avoidance experiments show that the proposed method can successfully plan a collision-free path in a cluttered environment and navigate the robot to the goal with high trajectory accuracy.

Because of the complexity of the modern industrial plant, it is difficult to get the proper mathematical model of the system by using the traditional methods. This makes it difficult in designing the best system controller. According to the control circumstance, the characteristics of control plant and the control aim, choosing the proper system identification algorithm is often a good measure to resolve this kind of problem. In this paper, we choose a generalized least squares algorithm as a system identification algorithm and get the differential equation model of the autonomous navigating intelligent vehicle system (ANIVS). Using this model in the experiment, we resolve the problem of the modeling and control of the steering system of ANIVS satisfactorily.

Modeling traffic flow dynamics using cellular automaton (CA) allows one to run a complex signalized intersection simulation with comparatively low computational effort. The authors examine various realistic generalizations of the basic cellular automation model used in traffic simulation and give a new CA model to describe the dynamic traffic transition at a signalized junction. Traffic jam and delay induced by a two-dimensional crosscut road are discussed. Using this model, the authors simulate the dynamic traffic flow in each direction changing lane under different rules. Comparison of the output shows the effectiveness of the input traffic management strategies.

The increasing utilization of mechatronic systems in vehicles requires the integration of diagnosis functions which will be widely implemented as onboard software in the vehicle. These diagnosis functionalities will be based in the future on functional and mathematical models and will enable the depth of diagnosis to be improved. The ascertained data from the diagnosis functions describe the overall condition of the vehicle and are stored in nonvolatile memories. The development of mobile telephones capable of handling data and the increased availability of wireless networks build up the second basis of mobile diagnosis. Using a suitable IT infrastructure, data can be obtained from the vehicle by every PC. In addition to the data channel, which allows precise vehicle identification and describes the condition of the vehicle, customer complaints can be dealt with over the voice channel and serve as a fundamental source of information. Vehicle data as well as the information from the driver are compared with previously occurred faults in other vehicles. Case based reasoning (CBR) systems applications are identified. The result is a precise ascertainment of the fault cause, from which the defective vehicle components can be determined. Thus, service vehicles can carry with them correct replacement parts which can be inserted directly at the customers location in order to remove the fault. Mobile diagnosis allows an optimized diagnosis and repair process particularly if vehicles breakdown far away from a workshop.

In the intelligent traffic system (ITS), vehicle saturation degree data of every road section must be sent to users accurately, in real-time and reliably, so their data amount is enormous. In order to improve the utilization ratio of a signal channel, this paper puts forward a new method of transmission of traffic flowing data, that is sectioning transmission of vehicle saturation degree data and color mark in electronic map. As according with Gauss distribution, in terms of the principle of equal probability, the saturation degree data can be divided into several section such as 74%-100% stands for jam, and every section can be coded by a 1-bit number. In the electronic map of user, the saturation degree data of every road section can be marked by color such as green stands for free, bright red stands for jams and so on. The experiments have proved that this method can improve utilization ratio of a signal channel largely, the effect is good.
