BMW ActiveAssist system lets self-driving cars get sideways and keep you on the road

Car and tech companies are working hard to prove that autonomous vehicles are safer and more responsible than humans. BMW apparently didn’t get that memo.

At the 2014 Consumer Electronics Show, BMW unveiled ActiveAssist, a limited autonomous-driving system that can take control of a car in adverse situations. That means the BMW 2 Series ActiveAssist prototype just might be the world’s first self-drifting car.

However, the goal of ActiveAssist isn’t to make robotic cars as irresponsible as the humans they’ll replace, it’s to make driving at the limit safer.

BMW says the system can intervene in situations like hard cornering, abrupt lane changes, and hydroplaning to bring the car back into line, while driver presumably holds on for dear life.

In that respect, ActiveAssist may just be the next logical step beyond today’s electronic driver aids, which already take a lot of the work away from the driver. It might also be easier to sell autonomous driving as an emergency-only backup to skeptical humans.

Like other semi-autonomous systems currently on the market or in testing, ActiveAssist relies on hardware and sensors that are already available.

For speed control, ActiveAssist can brake individual wheels, which also has the effect of nudging the car back into line. The system can also steer a car, including counter steering and plying brake force to counteract oversteer and avoid spins.

BMW did not say when ActiveAssist will be offered on a production car, but it did say the system was in the late stages of development, and that it could form a stepping stone to a fully-autonomous car.

If the system does make it to showrooms, it could provide drivers with a wider safety net, all while getting people used to the idea of a car that drives itself. In the future, BMW may still make the “Ultimate Driving Machine”, but with an emphasis on the machine.

Waymo puts its self-driving cars back on Arizona roads as lockdown is eased
waymo

Waymo says it’s ready to return its self-driving cars to the streets of Arizona.

The autonomous-car company paused most of its public-road testing in March in response to the worsening coronavirus pandemic. Specifically, the company parked cars that picked up passengers as part of its Waymo One ridesharing pilot, as well as those that drove without passengers but required a safety engineer to be on board. Vehicles that could operate safely without an engineer remained on the streets, though only a small number of these have been operating.

ford releases self driving car data to researchers

Ford's self-driving car program is experiencing delays, but the automaker hopes that others will pick up the baton. Ford is releasing what it calls a "comprehensive self-driving vehicle dataset" to researchers. The goal is to promote further research and development of autonomous driving tech, Tony Lockwood, Ford autonomous vehicle manager, said in a blog post.

The package comprises data from multiple test vehicles operating in Detroit, collected over a one-year span, Lockwood said. The testing that generated this data was separate from work Ford is doing with Argo A.I. to develop a production-ready autonomous driving system, Lockwood noted.

Waymo keeps autonomous driving simulations running as cars stay parked

Waymo parked its fleet of prototype self-driving cars in response to the coronavirus pandemic, but that doesn't mean the company has stopped working on autonomous driving tech. Even with employees working from home, Waymo is still capable of running simulations 24 hours a day, seven days a week, continuing to develop autonomous driving systems, a company press release said.

Simulations were a big part of Waymo's operations before the pandemic. One day in simulation is equivalent to 100 years of real-world driving, according to Waymo. The majority of development work on any new piece of software is already done in simulation, before being released for use in actual cars, the company noted.
