Nissan Autonomous Emergency Steering System announced [video]

Aims to reduce collision at high and low speeds

Nissan has unveiled their Autonomous Emergency Steering System (AESS).

Based on their steer-by-wire system, the AESS will automatically apply the brakes and steer the car when a collision is imminent. The system is designed to work at high and low speeds when the driver fails to notice an impending crash.

The system works by processing information provided by a front-mounted camera, five laser scanners and three radar systems which are mounted at the front and on both sides of the vehicle. If the system determines a collision cannot be avoided by braking, it looks for an open area ahead of the vehicle. The driver is then notified of where to steer but if they fail to react, the car will automatically steer itself in that direction.

There's no word on when the system could be introduced in production vehicles, but Nissan says the AESS is a key part of their Vision Zero safety initiative which aims to eliminate traffic fatalities.

YOKOHAMA, Japan (October 17, 2012) - Nissan Motor Co., Ltd. today announced the development of the "Autonomous Emergency Steering System."

This system offers a high level of collision avoidance capability by applying automatic braking and automatic steering in situations where a collision is imminent and evading obstacles by braking may not be effective. The system takes effect in situations where unpredictable risks arise, such as sudden intrusions onto the road in low speed zones, or when a collision at high speed is imminent due to the driver's delayed recognition of the tail end of a traffic jam.

Nissan has long worked on the development and commercialisation of brake-based control technology. The company has recently promoted development of technology to deal with situations that cannot be mitigated through braking alone. In order to prevent an accident from occurring, technology is needed to identify potential obstacles. Nissan has succeeded in developing technology which, through high-precision sensing technology and on-board control technology, automatically steers the vehicle away from potential collisions, when braking alone is insufficient.

The Autonomous Emergency Steering System, using the information provided by the front-mounted radar and camera, the two left and right rear radars, and the five laser scanners attached around the vehicle, initially acts on a risk of collision that cannot be avoided by braking. Simultaneously, it checks if there is a forward zone free of obstacles and that there are no vehicles approaching from the rear, and then displays to the driver the direction that the vehicle should be steered. If the driver cannot immediately steer in that direction, the system takes over to automatically steer the vehicle to help avoid a collision.

Nissan has established the Vision Zero safety goal, which aims to help eliminate traffic fatalities and serious injuries. The guiding force behind this goal is the concept of the "Safety Shield," which identifies six stages of driving conditions, from "normal driving conditions" through "post-accident condition", and works to provide the most effective counter measure against sources of danger which occur at during each stage. The "Autonomous Emergency Steering System" is based on this initiative.

Sounds promising although I'd love to see what one would have to sign off legally when buying a car with this feature. All-in-all, it's a welcome step forward. I'd be curious how it would work with cars running in the left lane and there's a few feet of space to fit in between - can it do it, or is that still being worked out?

What if a pedestrian stepped out onto the road, but there was a car coming the other direction? Would it go for the pedestrian or the oncoming car?

It would apply the brakes.
