Bosch pursues the aim of sustainable mobility, which is low in harmful substances and does not rely on fossil fuels.
A growing number of people around the world own their own vehicles, especially in Asia and eastern Europe. Bosch is making a significant contribution to shaping developments in the area of personal mobility. In so doing, we strive to achieve low-carbon, sustainable mobility solutions that do not depend on fossil fuels. For instance, in cooperation with our customers, we are researching ways in which conventional and alternative drive technologies can be combined with one another, as well as possibilities for purely electric driving. At the same time, we continuously improve the internal combustion engine. Our aim is to reduce its fuel consumption by another 30 percent in the years to come.
In the medium term, the number of newly registered vehicles with internal combustion engines will continue to increase around the world. For this reason, legislation to limit CO₂ emissions has been introduced in several regions. In Europe, for instance, the CO₂ emissions of an average passenger car will have to be reduced from 130 grams per kilometer today to 95 grams in 2020. The company has already developed many fuel-saving technologies.
Gasoline direct injection: As early as 1951, Bosch launched a technology for gasoline engines. The system sprays fuel at high pressures directly into the combustion chamber. This enables higher engine compression, which translates into greater efficiency. As a result, gasoline engines with direct injection can perform better and are more fuel-efficient. Combined with downsizing and turbocharging, gasoline direct injection contributes to a CO₂ reduction of up to 12 percent. Since the year 2000, an equivalent technology has also been available for diesel vehicles.
Coasting function: With the start/stop system, driving vehicles that operate with diesel or gasoline engines can be emissions-free, noiseless, and low-resistance over considerable distances. The engine is automatically turned off whenever the vehicle can maintain its speed while coasting. On average, coasting reduces fuel consumption by up to 10 percent.
Predictive navigation: The system connects map data with the vehicle’s drive system. Using the preview of the road ahead, the engine management system can automatically determine how much power the powertrain needs and controls the internal combustion engine. This enables fuel savings of up to 15 percent.
Driving a car without producing CO₂, which is harmful for the climate, is the aim the gradual transition from conventional internal combustion engines to battery-operated electric cars. Bosch already offers important components to this end.
Systems for hybrid vehicles: With this type of system, the electric drive takes over for the internal combustion engine in fuel-intensive driving situations such as starting or accelerating. CO₂ savings compared with the internal combustion engine: up to 25 percent.
Systems for plug-in hybrids: These vehicles are equipped with an internal combustion engine and an electric motor. They can be operated either individually or simultaneously. The integrated lithium-ion battery is charged before the start of a trip, which gives vehicles a longer range than hybrids with motor generators. CO₂ savings: 65 percent.
Systems for electric vehicles: For purely electric vehicles, Bosch offers electric motors and power electronics in addition to chargers, batteries, and regenerative braking systems. Electric vehicles are a milestone on the road to independence from fossil fuels, as they do not need any fuel and thus do not produce any CO₂.
The feasibility of the electric car depends mainly on three factors: a range that meets most drivers’ everyday needs, an affordable battery price, and an adequate charging infrastructure. In all three areas, Bosch is cooperating with partners from industry and science to come up with promising solutions. Each year, the company spends some 400 million euros on its e-mobility research and development activities.
Some 1.3 million people around the world die as a result of traffic accidents each year. This is why the United Nations has declared 2011-2020 the “Decade of Action for Road Safety”. The aim is to cut the number of traffic-related deaths by half during this period.
Bosch has been working to improve road safety for decades. For instance, its ESP® electronic stability program went into series production in 1995. ESP® detects imminent skidding and automatically intervenes to keep the vehicle on its course. According to studies, the anti-skidding system prevents almost half of all serious accidents involving only one vehicle. For this reason, ESP® has been mandatory for all newly registered vehicles in Europe since November of 2014.
Modern driver assistance systems help detect and prevent critical situations at an early stage. For instance, the Bosch driver drowsiness detection system analyzes the driver’s steering behavior and issues a warning if micro-sleep is imminent. By the same token, Bosch’s predictive emergency braking detects forward collisions and helps with braking. In the future, driver assistance systems will be able to support drivers in increasingly complex traffic situations. They may even be able to act on their own.
