Driver assistance systems have arrived in the mass market. The majority of vehicle manufac- turers offer selected functions, depending on the model, as options or even as standard, also in the smaller classes. Thanks to increasing sales quantities, this democratization of the systems enables interesting safety packages and affordable prices to be offered to drivers of small and medium-class cars too. Ultimately, due to the increasing rate at which driver assis- tance systems are being installed, traffic safety levels are also expected to increase.

In addition to the consumers themselves, consumer protection organizations have also recognized the benefits of driver assistance systems. For this reason, from 2013, these systems will also be included in the test cata- log of the consumer protection organization Euro NCAP (European New Assessment Program), which is used to test and evaluate the safety of a new car using a 5-star rating system. In future, vehicle manufacturers will only be able to receive the full number of Euro NCAP stars and therefore the quality seal for the highest level of safety for their new cars if they offer a minimum level of driver assistance systems as standard. 6 | Chassis Systems Control | Bosch study on driver assistance systems 2012

Overview — Driver assistance systems

On the following pages you will find information about the functions presented in the study.

Road Sign Recognition with speed control This system shows you the applicable permitted speed and overtaking restrictions in the display. If you are driving too fast, your vehicle will be braked according to the tolerances you have specified. You can switch the system off at any time.

Lane Keeping Support If you should be distracted or are not concentrating and would leave the lane unintentionally, the system can keep you steady in the lane by means of gentle steering interventions. You can switch the system off at any time.

Construction Zone Assist This system guides you through construction sites and narrow roads. It warns you before traveling through narrow points, for examp- le, before you overtake in a critical situation in the construction site area. Bosch study on driver assistance systems 2012 | Chassis Systems Control | 17

Blind Spot Detection The system looks to the side and behind when driving. If there is a vehicle in the blind spot, a lamp lights up on the exterior rear-view mirror, for example.

Evasive Steering Support If, when a rear-end collision is likely to occur, even applying the fully will no longer be able to prevent an accident, then this system comes into play. It independently checks the available space in the lane to the left and/or to the right and automatically steers your vehicle into the lane that is free.

Rear Cross Traffic Alert This system monitors the road to the right and left for you when reversing out of a parking space. If there is likely to be a collision with an approaching vehicle, you will be warned and your vehicle will be braked.

High Beam Control This system detects oncoming traffic and vehicles ahead and automatically switches from high beam to low beam. Once the road is empty again, high beam is switched back on. 18 | Chassis Systems Control | Bosch study on driver assistance systems 2012

Overview — Driver assistance systems

Automatic Emergency Braking at low speeds At low speeds, for example when in town, the system can prevent rear-end collisions by means of automatic braking.

Automatic Emergency Braking at higher speeds If you should be distracted at a speed above 50 km/h (31 mph) and there is the possibil- ity of a rear-end collision with a vehicle, the system gives you an early warning. If you then do not brake sufficiently, the system provides the missing brake pressure. If you do not re- act at all, the system brakes automatically.

Automatic Emergency Braking for pedestrians If a pedestrian should run out in front of your car unexpectedly and you do not react, the system will warn you and assist you when braking. If you react too late, the system will try to avoid the collision or reduce the severity of the accident by means of automatic emergency braking.

Parking Maneuver Assist The system detects available parking spaces of a suitable size (lengthwise, cross- wise, diagonal). It automatically parks the vehicle in the parking space, following driver approval, using independent braking and steering. This system also works in a garage or on your parking space at home.

Bosch study on driver assistance systems 2012 | Chassis Systems Control | 19

Adaptive Cruise Control (ACC) You set your desired speed and your vehicle follows the car in front with automatic accelerating and braking. In so doing, it maintains the safety distance set by you.

ACC Stop & Go In traffic congestion, your car brakes to a standstill and then drives off again auto- matically. You set the permitted speed and your vehicle follows the car in front with automatic accelerating and braking.

Traffic Jam Assist at up to 60 km/h (37 mph) In a traffic jam or in traffic congestion below 60 km/h, you can hand over braking, accel- erating and steering to the system. Once the congestion eases and the traffic starts moving again, the system hands back to you. You can override or switch off the system at any time.

Intersection Assist The system assists you when turning left. It continuously monitors the oncoming traffic and warns you of any impending collisions. If you do not react in time, the system can avoid an accident by means of automatic braking. Robert Bosch GmbH Chassis Systems Control
