Bosch unveils parking space measurement system
While Toyota already has its self-parking Prius on the streets, and Volkswagen (not to mention BMW and Honda) isn’t too far behind, Citroën is joining the fold thanks to a newly-unveiled system developed by Bosch.
The Citroen C4 Picasso has become the world’s first car to feature integrated parking space measurement. The Bosch driver assistance system tells the vehicle’s driver whether the prospective parking space is long enough for the car. The parking space measurement in the C4 Picasso is based on the Bosch parking assistant, which helps drivers avoid shunting other cars and obstacles while parking.
The system establishes which side the space is on by identifying which turn signal is in use. While driving past – at a speed of up to 20 kilometers per hour – the sensor then gauges the space. The assistant indicates to the driver via the central display whether the gap is big enough for the car, a tight squeeze, or simply too small. The same visual and acoustic signals that feature in the parking assistant then warn the driver of any obstacles. Bosch parking space measurement also works for parking spaces that are on a slight curve.
Bosch will soon release more functional enhancements for its ultrasound-based parking assistant. At the beginning of 2008, a system will be going into series production that will both measure the length of a space and suggest the best way to steer and maneuver into the space. A further development level in the same year will make it possible to directly control electrically supported steering – the driver will only need to operate the gas pedal and brake, while the parking assistant will take care of the steering.
