This impressive system-on-chip supports Linux, Android, QNX Neutrino RTOS, Green HillsIntegrityRTOS, and others operating systems. Development tools include an ICE for ARM CPU available from different vendors, and a development board with “car information system-oriented peripheral circuits” that can be used as a software development tool for application software. However, unless you decide to start a car company you probably won’t be able to buy this type of chip or evaluation board… Nevertheless, it could end up in your semi-autonomous car in a few years as while sample are available now, mass production is scheduled to begin in March 2018, with ramping up to 100,000 units per month taking place in March 2019.


自治车是一个确定的东西Google self-driving cars已经在某些道路上(速度慢)和公式e甚至规划了无人驾驶比赛因此,真正的问题是解决技术挑战可能需要的时间,解决法亚博体育官下载规,并使公众对自动车辆充满信心。上面的Renesas'路线图显示R-Car H3将用于2018年的障碍物检测,半自动驾驶(ADAS =高级驾驶员辅助系统) in 2019, while fully autonomous cars may launch around year 2020 and beyond with the next generation (R-Car H4 ?) platform.

“Autonomous car are a sure thing, with Google self-driving cars already on some roads…”

I just wonder a couple of things about self driving cars:


(2)如果车上有瞬间的决定between swerving into a crowd of people or a head-on collision with a semi what choice is made here?

It’s way to soon for these things to be out on the road without somebody having answers for these types of questions.

Too bad it’s only for cars. Could be the base for an awesome PC replacement or a future proof TV box.

No doubt that software developers have full knowledge about your questions. But obviously the companies do not like it to be publicly discussed…
