Fully automated parking
Today’s cars can drive themselves in and out of parking spots completely unassisted – conveniently controlled from the curbside using a smartphone. This is possible thanks to Bosch’s Automatic Park Assist and its remote control function.
Thanks to this innovation, tight parking spots – even ones that are barely wide enough to open the car doors – won’t be a problem much longer. You’ll simply get out of the car in front of the parking spot, open the Bosch app on your cell phone, and press and hold a button to start the parking maneuver. The vehicle will then drive itself into – and back out of – the spot without anyone at the wheel. To abort the parking maneuver, you simply take your finger off the button.
Automatic Park Assist is likely to be available from 2015, and represents an evolution of the Bosch parking assistant that has been on the market since 2008. The parking assistant works on the basis of ultrasound sensors integrated into the side of the vehicle, which scan the surrounding area and identify suitable parking spaces. The system electronics then compute the most favorable steering maneuvers and automatically guide the vehicle in and out of the parking space – in the current version, however, the driver controls the car by accelerating, braking, and changing gear.

Predictive emergency braking system
When you’re stuck in traffic and your attention drifts, an accident can happen before you know it. Many rear-end collisions happen at low speed in traffic jams or on congested city streets.
The predictive emergency braking system developed by Bosch aims to prevent such collisions, or at least reduce their severity.
If the system detects that the car is coming dangerously close to a moving or stationary vehicle at speeds of up to 30 km/h, it prepares for a possible emergency braking maneuver. This way, the car’s full braking capacity can be deployed hundredths of a second earlier than usual – which can prove invaluable.
If the driver fails to react to the impending danger, the system can automatically trigger a full braking maneuver to prevent a collision.
The system, which is based on the networking of radar sensors with the ESP® electronic stability program, continuously analyzes the traffic in front of the vehicle.

Staying safely on course
If a driver is fatigued, distracted, or loses concentration and unintentionally allows the car to drift too close to the lane’s edge, the lane-keeping assist automatically steps in.
Activated from speeds of 60 km/h, the system uses an integrated camera to detect lane markings in front of the vehicle. It collects data on up to four lanes, even if the lane markings are briefly interrupted on one side. The system kicks in when it ascertains that the vehicle’s proximity to the lane markings is less than the minimum defined distance. In vehicles with electric power steering, the system can make gentle but perceptible steering corrections.
However, drivers can overrule the function at any time and continue to be responsible for the vehicle. When the turn signal is activated – that is, they want to intentionally cross lanes – the system does not intervene.
This driver assistance system is made possible by the multi-purpose camera (MPC) from Bosch, which also supports and improves radar-based functions such as adaptive cruise control (ACC), predictive emergency braking (forward collision warning), road-sign recognition, light control, and driver drowsiness detection.
