Toyota plans to make an advanced anti-collision system available to consumers sometime by the mid-2010’s. The technology, called Automated Highway Driving Assist (AHDA), will first be introduced in Japan.
The AHDA system will combine two automated driving technologies. The first is Cooperative-adaptive Cruise Control, which wirelessly communicate with preceding vehicles to maintain a safe distance. An added advantage to the employment of Cooperative-adaptive Cruise Control is that by reducing unnecessary acceleration and deceleration, the system improves fuel efficiency while helping to reduce traffic congestion.
The second is Lane Trace Control, which employs high-performance cameras, millimeter-wave radar and control software to aid steering and keep the can within an optimal driving line within the lane regardless of speed.
Basically the AHDA system will use sensors to locate first locate cars, pedestrians and other obstacles and then take appropriate actions if required. The system will not only brake if required, but take control of the steering to avoid hitting object the sensors have determined are in the car’s path. The AHDA system will first gives the driver an opportunity to react first by bringing up a visual cue and triggering an audible alarm before taking action on its own. The goal isn’t to take complete control away from the driver, but rather to help improve safety.
These technologies will be deployed in limited situations at first, with trials conducted on the Shuto Expressway near Tokyo. Initial trials are to begin October 15th.
