Toyota Motor Corporation announces that it has developed a next-generation advanced driving support system, Automated Highway Driving Assist (AHDA), which uses automated driving technologies to support safer highway driving.
AHDA links two automated driving technologies to support safer driving and reduce driver workload: Cooperative-adaptive Cruise Control, which wirelessly communicates with preceding vehicles to maintain a safe distance; and Lane Trace Control, which aids steering to keep the vehicle on an optimal driving line within the lane.
Toyota recognizes the importance of the driver being in ultimate control of a vehicle and is therefore aiming to introduce AHDA and other advanced driving support systems where the driver maintains control and the fun-to-drive aspect of controlling a vehicle is not compromised. Toyota plans to market the newly developed AHDA in the mid-2010s and other driving support systems as soon as possible to provide safe and secure means of transportation.
Automated Highway Driving Assist (AHDA)
Cooperative-adaptive Cruise Control
In contrast to standard radar cruise control (which uses millimeter-wave radar to detect other vehicles), Cooperative-adaptive Cruise Control uses 700-MHz band vehicle-to-vehicle ITS communications to transmit acceleration and deceleration data of preceding vehicles so that following vehicles can adjust their speeds accordingly to better maintain inter-vehicle distance. By reducing unnecessary acceleration and deceleration, the system improves fuel efficiency and helps reduce traffic congestion.
Lane Trace Control
Lane Trace Control, which features completely new Toyota automated driving technologies, employs high-performance cameras, millimeter-wave radar and control software to enable an optimal and smooth driving line at all speeds. The system adjusts the vehicle’s steering angle, driving torque and braking force when necessary to maintain the optimal line within the lane.
More Driving Assistance for Elderly Drivers
Within Japan, Toyota has been testing its next-generation Intelligent Driver-support System on public roads for approximately two years.
Based on the insights gained from automated driving research, Toyota aims to provide advanced driving support systems optimized to help enable safer driving and contribute to realizing the ultimate goal of any society that values mobility: the elimination of traffic fatalities and injuries.
In anticipation of the super-aging populations of the future, these advances will also be used to develop technologies that support senior drivers with recognition, decision-making and vehicle operation, with the aim of achieving a mobility society where they can lead fuller lives. Furthermore, Toyota is working to provide more stable driving environments that contribute to the alleviation of traffic congestion, thereby reducing economic loss and CO2 emissions.
