Steering torque feedback provides drivers with road feel and hap tic feedback on vehicle motion, which are necessary for drivers to properly operate vehicles. Therefore, simulating steering torque feedback with sufficient fidelity is of great significance to systems without actual steering systems, such as driving simulators and steer-by-wire systems. In this paper, a steering torque feedback model...
Based on the sensitivity analysis results, the parameters in the steering torque feedback formulation (Eq. (1)) is adjusted. For verification, the simulation results based on steering torque feedback model are compared with real vehicle experimental results, as shown in Fig. 3. The results show that the simulation matches well with the real vehicle experiment, which demonstrates that the proposed...
In this study, the cellulase gene celD from Clostridium thermocellum was cloned into expression vectors pET-20b(+) and pHsh. While high expression can be achieved by means of both these expression systems, only the pHsh expression system gives soluble proteins. By weakening the mRNA secondary structure and replacing the rare codons for the N-terminal amino acids of the target protein, the expression...
