This paper proposes an antilock braking system (ABS) control method for maximizing tire-road friction and minimizing yaw moment of a commercial vehicle. First, a target slip ratio-based ABS control strategy has been described based on Lyapunov theory. Under this method, slip ratio is controlled in stable range precisely and rapidly. As fixed target slip ratio of ABS controller is not able to provide optimal road friction when a vehicle brakes on butt road and μ-split road, a variable target slip ratio method has been proposed to further improve tire-road friction and decrease yaw moment caused by longitudinal tire-road friction. Vicinity estimation and actual adhesion-based estimation have been introduced to estimate optimal target slip ratio. After a series of simulation tests, the method proposed in this paper has been proven to be effective.

A simulation test and analysis system for ABS control strategy was developed through the joint of VC++6.0 development platform and MATLAB/Simulink simulation platform. And the simulation test for ABS control strategy on four typical roads was carried out. Besides, the test results were analyzed. The test results showed that the system is able to give a good simulation of vehicles and roads and has the capacity of offering a good detection analysis.

EREV is a new development direction for the future automobile industry. The power train structure changes make it necessary for the thermal management system to be redesigned according to the driving condition and thermal coupling analysis. The heat sources are analyzed, a new thermal management schedule is built and relative parameters are determined based on a passenger car platform.

The Digital Mock-Up (DMU) technology is one of the most significant means to the development and innovation of new products in modern manufacturing enterprises. The application of the DMU technology can help improve the quality of products, reduce the production cost and shorten development cycle. In this work, the DMU of the whole automobile chassis is constituted according to the unique characteristics of design and development for automobile chassis. The focus is on the DMU harmony analyses, including interference checking, disassembly and assembly simulation, space location, structure intensity and modal of vibration‥ This paper also provides an optimal and instructive method to the design and development of other complex systems.
