This study aims to investigate the effect of chemical treatment of Jute fibers and the addition of MCC (microcrystalline cellulose) on the strength of the hybrid laminated composite (HLC). The HLC was fabricated using the press mold method with a pressure of 2 bar. The physical characteristic was evaluated by SEM, FTIR and XRD. The results show that the MCC’s filler addition to treated jute/glass fibers increased the interlaminar bonding. The HLC has the highest mechanical strength by a combination of treated jute/glass (JGJGJG), in which the resulted in tensile and flexural tests are 73 MPa and 183 MPa, respectively.
GPF system is expected as a solution for PN/PM regulation which is becoming stricter in gasoline engines. The management system of GPF temperature and residual soot amount in GPF is necessary for the GPF system to execute GPF regeneration control safely and effectively. Therefore, in this study, logics were investigated for GPF temperature and amount of residual soot, and the logics were verified by a test vehicle. This paper describes the development process and verification results.
This paper focused on different types of passenger vehicles vs. small scooter type E-bike collisions for AF05 bicyclists. Detail FE bicyclist human body model (HBM) and E-bike are developed. It is observed that (i) location of head impact (WAD) matches the recent CNCAP proposal and (ii) bonnet leading edge (BLE) height which varies with vehicle profile influences overall kinematics of the bicyclist. Hence, future head protection guidelines for bicyclists should be based on real-world accident statistics of that region.
Recently, many companies have been working on developing technologies for automated driving. For automotive companies, one of the challenges is to realize the automated driving with safety and reliability. This paper addresses a trajectory generation method using model predictive control (MPC) for the control development of the automated driving. Using the MPC, the design method of a steering control will be proposed in order to generate trajectory and develop a practical algorithm considering a product implementation. More concretely, we propose the design method of 1) online trajectory generation to maximize use of an entire road width like a skilled driver that has a significant experience in driving and 2) smooth trajectory correction whenever the vehicle slips away from an appropriate trajectory, which are useful for actual product development.
