Automated drivingWith an increasing level of automation, driver assistance systems will reduce the burden on the driver ever more. With each innovation, we move a step closer to the goal of accident-free and fully-automated driving.

Automated driving – behind the scenes:product and project managementWe need a new form of mobility for our increasingly networked world – andthat means we’ll need different cars. Comfort and better traffic flows aren’tthe only factors involved here, but also an aging population. With driver assistance systems, we will come even closer to Bosch’s vision of accident-free driving.

Automated driving – behind the scenes:driving strategyThe driving strategy regulates how the automated vehicle behaves in traffic, and determines the values required for vehicle control. The vehicle system must decide for itself where to drive and when to accelerate, brake and steer — and all this on the basis of information that changes extremely quickly.

Automated driving – behind the scenes:surround sensingAs the vehicle has to move independently in real traffic, it must be able to detect all relevant road users around the vehicle (360°), and reliably select the correct lane. To do so, every section of the vehicle is monitored by multiple sensors with differing measurement principles.

Common-rail diesel injection system CRS3-20The common-rail system is modular in design. The right combination of high-pressure pump, injectors, rail, and electronic control unit results in systemsfor all types of vehicles, from the smallest passenger cars right up to thelargest luxury sedans.

Worldwide potential of dieselDr. Markus Heyn, president of the Bosch Diesel Systems division, explains the worldwide potential of diesel.

FlexFuelThe Bosch systems for powertrains with FlexFuel engines can run ongasoline-ethanol mixtures with varying mixture ratios, from pure gasoline topure ethanol.

Continuously variable transmission (CVT)Continuously variable transmissions (CVTs) are stepless automatictransmissions with a Bosch pushbelt. By transmitting drive power efficientlyfrom the engine to the wheels, CVTs reduce fuel consumption and CO2emissions by up to 7 percent compared with conventional manual transmissions, and this without any loss of traction whatsoever.

Hybrid vehicleHybrid propulsion combines an internal combustion engine with an electricmotor. The electric drive unit supports the combustion engine, particularly in situations involving above-average fuel consumption such as driving off or accelerating. It helps to cut down fuel consumption and CO2 output, especially in urban traffic. Pollutant emissions are thus reduced.

Construction zone assistantIf the vehicle gets too close to the edge of the lane while driving through a construction zone, the system issues a warning or corrects the movement of the vehicle via a steering intervention, maintaining a safe lateral distance between the vehicle and lane boundaries.

Compressed natural gas powertrainThe compressed natural gas (CNG) powertrain shows great efficiency potential. Compared to gasoline, CNG combustion produces about 25 percent less carbon dioxide (CO2).

Start-stop coasting and boost recuperation systemThe boost recuperation system (BRS) from Bosch combines efficient functions to create a sophisticated and integrated system. Besides the integrated recuperation, boost, and coast functions, the BRS provides an innovative add-on to conventional start-stop systems. As an entry-level electrification variant, it plugs the gap between start-stop systems and full hybrids. It is also the basis for the 48-volt electrical system.

Electric vehicleAn electric vehicle no longer has a combustion engine on board. It runswithout fossil fuel. The electric drive contains a separate motor generator (SMG) that propels the vehicle electrically in motor mode, and generates electrical energy for the battery in generator mode.

Automated driving – behind the scenes:mapping and localizationHighly precise, dynamic position determination in real time is absolutelyessential for automated driving. It is crucial in order to guide the vehicle inch-perfect within the lane, and thus to avoid negatively affecting otherroad users.

Automated driving – behind the scenes:motion controlAn automated vehicle not only needs to master all traffic regulations, but itmust also have all the other skills that a human requires to drive a car. It must“see” and interpret its surroundings, make decisions independently, andoperate the accelerator, brakes, and steering wheel by itself.

Driver assistance systemsBased on intelligent sensor technology, driver assistance systems constantlymonitor the vehicle’s surroundings as well as the driving behavior to detectpotentially dangerous situations at an early stage. In critical driving situations,these systems warn and actively support the driver and, if necessary,intervene in an effort to avoid a collision or to mitigate the consequences of the accident.

Active pedestrian protectionBased on data supplied by the stereo video camera, the pedestrian protection assistant can trigger automatic emergency braking at speeds up to 60 kph, or if required, an evasive maneuver. The maneuver is carried out on the basis of 3D measurement of all moving and stationary objects in the vehicle’s vicinity. It helps to avoid or mitigates collisions with pedestrians.

Electronic horizonBy networking vehicle systems with electronic horizon data, Bosch is able todevelop numerous new functions that make for a safer, more comfortable, and more efficient driving experience. Information such as bend radii, inclines, and speed limits are directly integrated into vehicle systems using the standardized interface protocol (ADASIS v2).

Remote parking assistantToday‘s cars can drive themselves in and out of parking spaces completelyunassisted and conveniently controlled from the curb using a smartphone.This is possible due to the remote function of the automatic parking assistantfrom Bosch.

Powertrain

Plug-in hybridIn order to be able to drive longer distances on emissions-free electric power,the hybrid vehicle is equipped with a more powerful lithium-ion battery. This can be charged before the trip straight from a power socket by means of a battery charger. By comparison with an internal combustion engine, the plug-in hybrid reducesboth fuel consumption and CO2 output by an average of 50 percent.

mySPINmySPIN is the smartphone integration solution that creates a device-vehiclelink and ensures safe and reliable in-car use. It works by transferring the phone’s apps to the vehicle’s display.

Regenerative brakingWhen braking in a hybrid or electric vehicle, the electric motor switches to generator mode. The wheels transfer kinetic energy via the powertrain to the generator. The generator turns in a similar way to a bicycle light generator, transforming part of the kinetic energy into electrical energy, which is then stored in a high-voltage battery.

Gasoline direct injectionIn direct gasoline injection engines, the air-fuel mixture is formed directly inthe combustion chamber. The precise metering, preparation, and distributionof the intake air and the injected fuel for every combustion stroke leads tolow fuel consumption and low emissions levels.
