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...
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...
A new shock absorber with the combined mechanical-electromagnetic-hydraulic structure is proposed to recycle the energy dissipated by shock absorber in the process of driving. The suspension system built on the new shock absorber is generally called hydraulic transmission electromagnetic energy-regenerative suspension. This paper presents the working theories of the hydraulic transmission electromagnetic...
This paper gives a comprehensive analysis of the structure features and the problems of the existing energy-regenerative suspension systems, and proposes a new energy-regenerative suspension system design, Hydraulic Transmission Electromagnetic Energy-regenerative Active Suspension. The new suspension system combines mechanical-electromagnetic-hydraulic structure and can overcome the problems of the...
Automobile driveline test system is used to test and study the driveline components and assembly (DCA). This paper introduces the structure and principle of the test system, illuminates the application of frequency conversion technology in the test of the DCA. The drive system commands the drive motor to produce the necessary speed (RPM) and torque to simulate engine power. The actual driving resistances...
