Abstract(s)
A indústria automóvel está em constante mudança. A cada dia são desenvolvidos mais automóveis, com maior inteligência artificial e mais funcionalidades. As comunicações utilizadas são cada vez mais variadas e, por sua vez, exigem maior velocidade e segurança. A segurança do automóvel constitui-se uma prioridade e a Bosch sempre demonstrou ter um papel fundamental em fornecer soluções seguras, como é o caso do Electronic Stability Program (ESP). Trata-se de um sistema de segurança que ajuda o condutor a não perder o controlo do veículo, através da introdução de vários sensores no automóvel. Um destes sensores é o Steering Angle Sensor (SAS), que tem como função fornecer o ângulo da viragem do volante. A comunicação entre o SAS e o ESP tipicamente é feita através do protocolo de comunicação Controller Area Network (CAN), protocolo desenvolvido pela Bosch bastante robusto. Com a evolução das tecnologias, os fabricantes irão alterar as suas comunicações nos seus veículos, de modo a terem uma maior velocidade de transmissão. Surge assim o Flexible Data rate Controller Area Network (CAN FD), que é uma evolução do CAN, mas que torna possível o envio de dados mais rapidamente. Este protocolo de comunicação já está a ser implementado nalgumas aplicações pelos fabricantes de automóveis, sendo que num futuro próximo, será a única versão. Perante esta situação, foi proposto pela Bosch uma prova de conceito ao nível do Hardware (HW), uma nova versão de um sensor SAS mas com CAN FD.
The automotive industry is always changing. Each day are developed vehicles with more artificial intelligence and with more features. The communications that are being used, have more variety, more speed and more safety. The safety in a vehicle is a high priority and Bosch always have a fundamental concern to develop safety solutions, like Electronic Stability Program (ESP). This is a system which helps the driver to not lose the control of the vehicle, with the introduction of some sensors in the car. One of this sensors is the Steering Angle Sensor (SAS), which has the purpose of give the angle of the steering wheel. The communication between the SAS and ESP typically is made by Controller Area Network (CAN), which was developed by Bosch and it is very robust. With the evolution of technologies, the manufacturers will change the communication inside their vehicle, to have more transmission speed. Then appears the Flexible Data rate Controller Area Network (CAN FD), which is an evolution of CAN, but allow to send data faster. This communication protocol is already implemented in some applications by automotive manufacturers, and in a near future the CAN FD will be the only versions. Because of this, Bosch propose a concept proof in Hardware (HW) level, a new versions of SAS but with CAN FD.
