Fast processing, clever planning: The vehicle computer handles complex challenges

The automated cars of the future will be in control of all traffic situations which an excellent human driver should also be able to master. To do so, they constantly need to know where they are and what situations they face. Furthermore, they must be able to implement the planned driving strategy. But before that, automated vehicles need to decide in real time which driving strategy is the best in order to resolve the current traffic situation and reach their destinations safely (“Think”). This task is assumed by the vehicle computer which is responsible for thinking in its capacity as the car's brain, so to speak. Top priority in all decisions by the vehicle computer is given to the safety of all driving maneuvers.

In the development process Bosch is working intensively on fitting automated vehicles with adaptive artificial intelligence enabling them to drive like a human being – only more safely and efficiently. After all, unlike human drivers, technology never gets tired. It constantly perceives its entire surroundings and can react faster. Combining these strengths with sophisticated artificial intelligence is the key to automated mobility of the future. And the particular competence displayed by Bosch concerns exactly this combination.

Vehicle computer for assisted and automated driving (DASy)

DASy

Future versions of DASy will also support highly automated driving on the highway or in driverless taxis.

Simply safe decisions to master highly complex functions:

The vehicle computer from Bosch fulfills the highest safety and security requirements. With its impressive computing power, it masters partially automated driving functions. It processes information from the surround-sensor system into a precise model and uses the latter to simultaneously develop a safe driving strategy even at high speeds. This key component of automated mobility is already in production at Bosch. Future versions of DASy will also support highly automated driving on the highway or in driverless taxis.

Learning from experience – artificial intelligence accelerates development

Artificial intelligence (AI) is the term used to describe a process by which machines learn how to learn. Computer systems mimic human intelligence by performing intelligent behavior based on predefined or learned models. An AI system perceives its surroundings through e.g. cameras and sensors; it then interprets this information and derives actions from it.

Machine learning and deep learning can be classified under the generic term artificial intelligence. Machine learning describes a process by which computers can acquire knowledge autonomously. The most common method for this now is deep learning. With deep learning, a computer acquires its knowledge through an algorithm that analyzes large amounts of data and learns to draw conclusions from this data. For example: We want the algorithm of a system to learn how to identify stop signs. So, we show it one million images of stop signs, and the algorithm builds up a store of experience. Based on this, it is then able to identify other stop signs presented to it.

The core intelligence of automated vehicles lies in the software running on the vehicle computer in the form of adaptive algorithms. The software analyzes and interprets incoming data from the surroundings sensors. It can, for instance, identify whether an object perceived by the sensors is a stop sign, vehicle, pedestrian, or cyclist. It can furthermore determine whether the object is moving and, if so, in which direction and at what speed. Based on the interpretation models, it is also possible to derive the likely future behavior of these static or dynamic objects. This is how it learns the highly advanced skill of anticipation: After observing a very large number of objects during the development process, the system is able to determine their respective characteristic behavior, which helps it to make increasingly reliable predictions. This is similar to how humans can learn from experience. In future, thanks to the vehicle’s intelligence, it will be possible, for instance, to calculate the probability of a pedestrian crossing the path of the vehicle and so enable the brake system to be activated in good time. Its swift powers of perception and extremely fast response times mean that AI is a very powerful technology that will find its way into assisted and automated vehicles and, unlike a driver, will not tire.

The human being must be enabled to act as the controlling authority in all AI decisions. “Artificial intelligence is meant to serve humans. With the AI Code, we have provided our employees with clear guidelines for the development of smart products,” said Bosch CEO Volkmar Denner at the IoT industry gathering Bosch ConnectedWorld (BCW) in Berlin. “We want people to trust our AI products.”

Automated vehicles must have three fundamental skills: They need to perceive and interpret (Sense) their surroundings, use this information to make forecasts and derive a suitable driving strategy (Think), and then implement it reliably and safely (Act). Sensing the immediate environment is the task of the surround sensors which combines camera, radar and ultrasonic. Vehicle intelligence enabling it to interpret its surroundings and find the optimal driving strategy is made possible by software and algorithms which use the information gleaned from sensors as well as data from other connected systems.

Systems such as the powertrain, steering and brakes ensure that the respective driving strategy is then implemented on the road. This process of sensing, thinking and acting takes place during the entire journey. When applied to human beings, this process is similar to constant interactions in the body during which the sensory organs pick up stimuli which are processed by the brain before the nerve pathways, muscles and limbs implement the brain's control signals as actions.
