t of antilock braking system (ABS), for improving vehicle braking and handling performance, involves mechanism electronics, hydraulics, hardware and software design and field test validation, and also requires repeated field tests on various road conditions, which are not easily available. In the very beginning of product development for vehicle ABS, a huge amount of vehicle field tests are required to investigate the control laws by a great number of repeated modifications. Moreover, even in most repeatable test environments, the road conditions for field tests cannot be controlled exactly to be identical. This inevitably leads to increase of both development cost and cycle time for ABS product. Because of fierce petition in today39。 s business environment automotive industries suffer constantly increasing pressure of reduction in the development cost and time of new vehicle electronic products to meet the demands of market and urgent effective approaches to innovation of sophisticated vehicle electronic products. In this paper, a new rapid development method is proposed to develop and test ABS control system efficiently in laboratory environment, which covers the whole process of concept and function design, system modeling, offline simulation, code automatic generation, realtime hardwareintheloop (HiL) simulation and final vehicle test validation. This economical ABS rapid development system characterized by a parallel rather than a serial development process is built up with friendly interface for implementation of the present development procedure. The rapid development system is based on HiL simulation technology, and function of sensors and actuators of the control system are replaced by software to simulate a field test environment in a controllable situation. Therefore, consistently reproducible test conditions are provided and critical safety issues may be solved in the stage of electronic product development prior to invehicle tests. The present rapid development system is successfully employed in the ABS control system development and the developed control algorithm has been validated in the vehicle filed test. According to the test measures, the control precise is close to that of the original one. It is proved that t。
