ABSTATT, GERMANY – For the past several years, Bosch has been developing ever more capable safety and driver assistance systems to help relieve some of the burden of driving. With new functions and improved sensors, Bosch will continue to be a major supplier of technology and services to the automotive industry.
“Assistance systems make driving safer, less stressful, and more eco-friendly,” said Gerhard Steiger, the president of the Bosch Chassis Systems Control division. “With each innovation, we move a step closer to the goal of accident-free and fully-automated driving,”
Electronic aids already help drivers identify the best route to a destination, provide support in critical situations, and park the car at the end virtually without any input from the driver. In its quest to improve and expand these aids, Bosch is not only developing new systems, but also connecting existing ones to each other and, in doing so, creating new functions. These include, for example, making predictive driving possible and even relieving drivers of the burden of driving in certain situations. The ability for vehicles to communicate with each other opens up even more perspectives.
Bosch introduced the first electronically controlled antilock braking
system in 1978. It was followed by the first electronic airbag control unit in 1980, the “Travel Pilot” navigation system in 1989, the ultrasonic parking aid in 1993, and the ESP electronic stability program in 1995.
Thanks to its ability to actively brake a vehicle, the anti-skid system is the basis for many of today’s assistance functions. Electric power steering and environment-recognition sensor technology round off this extensive portfolio.
“Ultrasonic, radar, and video – Bosch possesses all the sensor technology necessary for driver assistance,” Steiger says, “and with our core competence in vehicle integration, we have the ideal basis for the development of new, even more capable assistance systems.”
When developing safety and assistance systems, Bosch pursues two
fundamental strategies. One is to create tangible customer benefits with new assistance systems that make driving even safer and more
comfortable. The second is to come up with innovations that make existing systems more cost-effective, so that they can be used in low-price vehicles and in emerging markets.
“Only widely-used safety technology can bring us closer to the goal of accident-free driving,” Steiger said.
In 2014, a new Bosch stereo-video sensor will go into series production. Among other things, it will offer fast and accurate 3D measurement of objects. It will also measure the distance to the vehicle ahead at speeds of up to 100 kph, and warn the driver when this distance falls below a safe minimum. This will improve pedestrian safety, and in addition will allow functions such as evasive action and construction site assistants to be realized.
By the end of this year, Bosch plans to expand its radar sensor portfolio to include a mid-range sensor. It uses the 77-gigahertz frequency band, which has been permanently allocated to automotive applications worldwide.
Drivers in Germany, France, and Italy are familiar with modern driver assistance systems, according to a market survey conducted by Bosch in these countries. Around two-thirds of all respondents were of the opinion that such systems improve both safety and comfort while driving. In all three countries, the predictive emergency braking system that recognizes pedestrians was rated the most important driver assistance function. Even fully-automatic driving now has many supporters. About half the respondents said they could imagine using an electronic chauffeur – as long as it could be switched off.
