Anti-lock braking system based on FlexRay protocol
The anti-lock braking system is nowadays a part of almost every vehicle. This system increases safety of the people sitting in the vehicle at the moment of stopping on a slippery or unstable road surface. The point is to assure a good controllability of the vehicle even if the wheels are in slip. In order to work properly, the anti-lock braking system needs to have actual information about the rotation of every single wheel. And the up-to-dateness and certainty of an accurate information is the primary criterion of an appropriate performance. Currently, the information about the frequency of wheel rotation is being transmitted via the current loop. This solution needs a lot of wiring, which means increased purchase costs. This paper describes a method, where the information from the rotation sensors of the wheels are transmitted into the control unit through the FlexRay bus. Additional wireless acceleration sensors located on the wheel are used to improve the ABS performance.
FlexRay controller with special testing capabilities
FlexRay is an incoming communication standard for automotive applications. Paper deals with an implementation of unique FlexRay communication controller in FPGA and shows examples of its usage for FlexRay Wakeup and Startup configuration parameters evaluation.
A Study on Technology Embedded English Classes Using QR Codes
The development of information and technology has brought plenty of changes to the educational environment. The prevalence of smart phones is particularly playing a huge role in shaping learning methods. Smart phones provide the opportunity to scan QR codes, which can greatly ease access to information. Due to a high recognition speed, recognition rate, and restoration rate, they can be useful tools for English teachers to use in their class. In this study, we suggest using QR codes for writing and picture descriptions. Based on this study, more research should invest in Technology Embedded English teaching models to create better English classes for students.
