Nissan Motor Co., Ltd. is developing the \"Autonomous Emergency Steering System.\" With this system, the vehicle will be able to avoid a collision as it will automatically apply braking and automatic steering in moments wherein a collision is about to happen and braking may not be effective at dodging obstacles.
This system gets activated in situations where there are unpredictable risks like abrupt intrusions onto the road in low speed zones, or when the vehicle is about to collide at high speed because the driver was slow at recognizing the tail end of a traffic jam.
Nissan has been working on the development and commercialization of brake-based control technology for a long time. Recently, Nissan has promoted the development of technology to handle situations that cannot be resolved by simply braking.
It found that technology is required to recognize potential obstacles so that accidents could be prevented from taking place. Nissan has succeeded in developing technology which, via high-precision sensing technology and on-board control technology, automatically steers the vehicle away from possible collisions, when just braking isn’t enough.
Data from the front-mounted radar and camera, the two left and right rear radars, and the five laser scanners positioned around the vehicle, are received by the Autonomous Emergency Steering System. It then immediately reacts to a collision risk that can’t be prevented by braking.
At the same time, the system verifies if there is an obstacle-free forward zone and if no vehicles are approaching from the rear. The driver is then informed which direction the vehicle should be steered. If the driver can’t steer in that direction right away, the system takes control and it steers the vehicle to help evade a collision.
