Toyota Automatic Highway Driving Assist

Advancements in our Active Safety technology

In the search for a world where vehicle collisions are eliminated, Toyota Motor Corporation (TMC) has made a significant step with the announcement of a newly developed safety technology.

Automatic Highway Driving Assist

Automated Highway Driving Assist (AHDA), is an advanced driving support system that aims to respond to the traffic environment by keeping the vehicle at a safe distance at all times, and reducing burden and fatigue on the driver.

With public trials held on the Shuto expressway in Japan, it links two automated driving technologies.

Cooperative-Adaptive Cruise Control

The first, Cooperative-Adaptive Cruise Control, wirelessly communicates with the vehicle ahead, transmitting data on acceleration and deceleration patterns to maintain a safe distance. This consistent driving pattern also saves fuel and reduces congestion.

Lane Trace Control

The second technology, Lane Trace Control, utilises high performance cameras, millimetre wave radar and sensors to detect lane markings and the position of the car. By doing this, the system will automatically adjust steering angle, driving torque and braking force to maintain a road position and reduce fatigue for the driver.

A safer future

TMC plans to bring AHDA with the supporting technologies to market in the second half of the decade as a part of its vision of a safer and more secure transport system that reduces fatalities and injuries to zero.
