Deflexion-angle is a crucial parameter for automobile controlling stability and safety. For constructing the basement of deflexion-angle detection, the model of semi-trailer train’s suspension is built and leaf spring dependent suspension is replaced with helical spring dependent suspension in the model. Balance suspension is adopted to distribute axle load uniformly. The mainly measuring parameters of stable steering performance including tractor speed, tractor’s lateral acceleration and semi-trailer train’s folding angle are also tested in the experiment. Comparison of experiment and simulation results show that there is consistency between the stable steering performance of established semi-trailer train’s model and real vehicle, and we can perform reliable analysis and research by the established semi-trailer train’s model.

Pseudorandom Sequences have been widely used in many areas such as telecommunication, cryptology, navigation and radar. m-sequence is one of desirable pseudorandom sequences. By utilizing the feedback functions of m-Sequences, a new method of constructing the feedback function of the nonlinear maximal length shift registers is presented. The feedback function is constructed by using of both the characteristic function and feedback functions from m-Sequences. Through the feedback functions, the nonlinear maximal length pseudorandom sequences are realized on FPGA. Meanwhile, the corresponding analysis demonstrates that this type of sequence has the desirable pseudorandom characteristic. It’s satisfactory and desirable.

The value of the chassis gap has an important impact on driving safety and handling stability of vehicle. Focusing on the efficiency and accuracy of the detection equipment for testing chassis gap, the controlling performance influenced by chassis gap and a novel tester model is presented. The finite element analysis is adopted to ensure the reliability of the tester proposed the Coulomb criterion and COSMOS / Works is selected to determine the safety factor as the time of the complex engineering analysis can be shorted by FFE technology which can minimize the design cycle, reduce the testing costs and improve product quality. Simulation results show that the dangerous place of the base assembly is the nearby regions of the double-rocker’s fixing holes where the limit stress is 2.398E+7N/m2 and the safety factor is about 26. The problem of detecting chassis gap accurately is resolved.

Rotation attack can destroy the synchronization of the watermark detector and the watermarking, even a slight rotating may invalidate the detection of watermarks. Resisting to the rotation attack, a blind video watermarking algorithm is proposed on the basis of combinding the Zernike moments and singular value decomposition (SVD). First choose the embedding areas on the luminance component. Then make the partitioning while doing the discrete wavelets transform (DWT) and make the singular value decomposition to the low-frequency parts. And last embed watermarks through modifying the maximum singular value. In detection, the possible rotation attacks to the video sequence would be corrected through Zernike moments. The experimental results show that the proposed algorithm is robust against conventional attacks and arbitrary angle of rotation attacks.
