Bosch Begins Japanese Tests of Autonomous Technology

January 22, 2016

Bosch has begun testing autonomous driving technology in Japan, following testing in Germany and the U.S., the company has announced.

Bosch said its initial goal is the development of the highway pilot, which will allow cars to drive autonomously on freeways and freeway-like roads starting in 2020.

“Because people there drive on the left, and because of the complex traffic conditions, Japan provides us with valuable insights for development,” said Dirk Hoheisel, a member of the board of management of Robert Bosch GmbH.

Worldwide, nearly 2,500 Bosch engineers are working to develop driver assistance systems and automated driving further. Like the engineers in Germany and the U.S., the team in Japan is already conducting tests with automated test vehicles on public roads. The test drives are being conducted on expressways around the cities of Tohoku and Tomei in the Tochigi and Kanagawa prefectures, as well as on the two Bosch proving grounds in Shiobara and Memanbetsu.

With their development activities getting under way, the new team in Japan is benefiting greatly from the findings of their colleagues in Germany and the U.S., who have been working on automated driving since 2011. Since early 2013, Bosch has been operating test vehicles on the A81 freeway in Germany and Interstate 280 in the United States.

“Our engineers have now completed more than 10,000 kilometers of test drives without an accident,” Hoheisel said.

The Bosch test vehicles guide themselves through traffic – accelerating, braking, and overtaking as necessary. They also decide for themselves, and depending on the traffic situation, when to activate the turn signal and change lanes. The basis for all this is sensors that provide a detailed picture of the vehicle’s surroundings. In addition, Bosch said its partner TomTom provides highly accurate map data. A computer uses all this information to analyze and predict the behavior of other road users, and on that basis makes decisions about the automated vehicles’ driving strategy.

If automated driving is to become reality in production vehicles, and not just in prototypes, the legal conditions for this have to be created. This matter is now on the political agenda in the U.S., Japan, and Germany. There are signs of impending change in the Vienna Convention on Road Traffic, which Germany has also ratified. On April 23, 2016, amendments to the convention will come into force. The member states will then have to transfer these amendments into national law. They allow automated driving so long as the driver is able to override or disable it. In the sphere of vehicle registration law, an informal working group of UNECE (the United Nations Economic Commission for Europe) has also begun looking at Regulation R.79, which only allows automatic intervention in steering up to a limit of ten kph. The validation of automated driving functions is another challenge. Using current methods, a highway pilot has to complete several million kilometers’ worth of testing before it can be released for production. Bosch is now working on entirely new approaches.

For Bosch, automated driving is about making road traffic safer. The UN estimates that 1.25 million people worldwide are killed in road accidents each year. Ninety percent of these accidents are caused by human error. Bosch accident research predicts that increasing automation can lower accident rates even further – by up to a third in Germany alone. And automated driving makes road traffic not only safer, but also more efficient. U.S. studies conclude that applying predictive driving strategies when on the freeway allow fuel savings of up to 39 percent, according to Bosch.

Even before it automates driving, Bosch said it is automating parking. Bosch’s automatic park assist is already in production. By smartphone remote control, the system autonomously maneuvers cars into parking spaces. Bosch active parking management, for instance, makes it easier to find a parking space. Sensors installed in the pavement indicate whether or not a space is occupied. They then pass on this information – to a real-time map that can be accessed on the internet, for example. This allows drivers to pick out an available space and navigate to it. And, in conjunction with Daimler, Bosch is going even further. Their aim is to revolutionize parking. Rather than having customers park and look for their cars, the vehicle drives it-self to a free parking space – and then returns on command to the drop-off point. To this end, Bosch is developing the necessary infrastructure for parking structures, including occupancy sensors, cameras, and communications technology.
