Toyota has been researching automated driving technologies since the second half of the 1990s and has conducted numerous road tests in the last years both in the US and Japan.
In order to make highway driving safer, Toyota Motor Corporation now announces its next-generation advanced driving support system, Automated Highway Driving Assist (AHDA), which uses automated driving technologies to support safer highway driving and reduce the driver workload.
The AHDA will be composed of two systems that will permanently monitor the traffic around, keep the vehicle distance and speed.
One of them is the Cooperative-adaptive Cruise Control, which uses 700 MHz band vehicle-to-vehicle ITS communications to transmit acceleration and deceleration data of preceding vehicles. This way, groups of vehicles will be “aware” of each other and adjust their speed to cruise at a safe distance permanently. This will also reduce fuel consumption and traffic congestion by limiting unnecessary acceleration and deceleration.
The other system wi the Lane Trace Control, which employs high-performance cameras, millimeter-wave radars and control software to adjust the vehicle’s steering angle, driving torque and braking force when necessary to keep the vehicle within one lane.
