Bosch develops ADAS system to prevent car-pedestrian collisions

Published: October 29, 2015 | Stuttgart

Bosch has plans for a pedestrian protection system that could be fitted to production cars as early as 2018. The system, developed at Bosch’s new R&D centre at Renningen, will automatically intervene if it senses that the driver’s own evasive action will not be enough to prevent a collision.

This system is part of a suite of technologies that Bosch is working on, with the ultimate aim of developing an autonomous driving function. The company believes it will be able to offer highly automated motorway driving by 2020 and the development of image processing systems, along with long and medium range radar sensors, is a major step towards making that a reality. 

It uses one of the company’s existing stereo video cameras to monitor pedestrians and oncoming traffic. An on-board computer – mounted in the boot in the case of the research vehicle – plots the likely trajectory of pedestrians within the camera’s field of view.

If a collision is thought to be likely the system will calculate the best way to take evasive action. But it doesn’t actually kick in until changes to the steering angle, vehicle speed and yaw rate indicate that the driver has initiated their own manoeuvre. From that point on, the system can brake or steer as required to prevent the collision, although the steering assistance is such that the driver can easily override it if necessary.

According to Dr Thomas Gussner from Bosch’s corporate research and advanced engineering department, provided the driver reacts at least half a second before a potential collision, the assistance system can help avoid it in 60 per cent of cases.
