【正文】 he method and the rapid development system are effective and efficient in the laboratory for reduction of expenses in field tests and development cycle. By considering a given precision requirement of realtime simulation, a vehicle system dynamic model for ABS should be presented as one important part of the ABS rapid development system, which has strong effect on the efficiency and effectiveness of the controller to be developed. The vehicle system dynamic model consists of vehicle model, neurotire model, brake model and hydraulic system model. The scheme for tests to build up and validate the subsystem model has been drawn up. Further, validation of the vehicle dynamic system model integrated by the subsystem model is made for the future research and the vehicle field test without the ABS has also been performed for verification of the precision of the builtup model under three conditions of pure braking, pure steering and braking while steering, respectively. By experimental results, it is shown that the vehicle system dynamic model for the ABS is correct and accurate, and can be used in the rapid development system. The design of the rapid development system and the way to realize its functions in the realtime simulation environment are presented. Under the direction of the proposed scheme, details of construction process of the ABS rapid development system including the software part, hardware part and interface part are discussed with consideration of its functions extended. The whole procedure of rapid development for ABS, ., offline simulation, generic realtime simulation, realtime hardwareintheloop simulation and the validation of the vehicle field test, based on this powerful development system, is further investigated by the ABS rapid development system. Use is made of the present method and the ABS rapid development system for research and development of the ABS controller systematically. The practical algorithm for the ABS control variables is presented, and based on the previous research achievements, the ABS controller is designed and embedded seamlessly in the rapid development system. The development procedure has been carried on according to the proposed method, and the developed ABS controller is then applied in the vehicl
