Veoneer launches new collision mitigation package for Polestar

Veoneer said it had launched its latest collision mitigation technology programme for Geely's electric Polestar 2.  

The supplier has begun production of the sensing technology and software which allows the EV to gather information and data about its surroundings and the trajectory of vehicles around it to assist drivers to avoid potentially hazardous situations. 

Key components of the technology suite include a fourth generation mono vision system, 77GHz front radar, and ADAS electronic control unit (ECU).

The Polestar 2 is the first vehicle to use the Zenuity sensor fusion software platform enabling claimed industry leading features like object detection, lane keeping aid, forward collision warning, adaptive cruise control, autonomous emergency braking, and traffic assist.  

Veoneer claims its front 77 GHz radar unit and windscreen mounted mono vision camera can spot "everything from disabled cars to pedestrians" and the system then warns the driver (via a brake pulse, audio warning signal, and visual warning signal in the driver display) and then brakes automatically if needed. Automatic pre-braking, steering support, and incrementally tightening seatbelts also come into play.

The mono vision system is designed with a 100 degree field of view and 1.7 megapixel resolution to support ADAS features necessary to achieve five star ratings for Euro NCAP.

The system is comprised of fully integrated hardware and algorithms using deep learning technologies that identify objects such as cars, road markings, or road signs.

The latest generation of 77GHz radars have improved performance and provide reliable and accurate situational awareness of objects surrounding the vehicle.

The radar design has improved waveform and operates at extended ranges needed to achieve five-star Euro NCAP ratings.

The ECU is the 'ADAS brain' of the vehicle and hosts a software feature stack along with feature software from other sensors to interpret the situation around the vehicle, and trigger ADAS features such as emergency braking or cross traffic alert.

The ADAS ECU is designed to be an open scalable hardware and software architecture that hosts algorithms.
