Toyota is conducting intensive tests for its autonomous cars. The technology is there and is developing fast, so Toyota wants to see how it performs in real world. 

The Toyota Research Institute (TRI) will introduce the TRI-P4 automated driving test vehicle on Jan. 7 at CES. The P4 is based on the all-new fifth-generation Lexus LS flagship sedan and will be used in TRI’s two-track Guardian and Chauffeur automated driving system development.

“Our Chauffeur development is focused on full autonomy, where the human is essentially removed from the driving equation, either completely in all environments, or within a restricted driving domain,” said Ryan Eustice, senior vice president of automated driving at TRI.

The P4 benefits from Lexus’ new generation of chassis and steering control technology, which provides greater agility and allows for more responsive and smoother maneuvers during automated driving.
 
P4 adds two additional cameras to improve situational awareness on the sides and two new imaging sensors – one facing forward and one pointed to the rear – specifically designed for autonomous vehicles. The imaging sensors feature new chip technology with high dynamic range. The radar system has been optimized to improve the field of view, especially for close range detection around the vehicle perimeter. The LIDAR sensing system with eight scanning heads carries over from the previous test model, Platform 3.0, and morphs into the new vehicle design.

P4 is a much smarter research vehicle than its predecessor. With greater computing power, its systems can operate more machine learning algorithms in parallel for faster learning.  It can process sensor inputs faster and react more quickly to the surrounding environment. All computing system power is now drawn from the vehicle’s hybrid battery with the 12v battery now serving only as a backup.
 
The compute box in the trunk, which serves as the “brain” of the automated driving system, has been reimagined. It is now tucked vertically against the rear seat transom, folding down to access the circuitry. This frees up the entire floor of the trunk for hauling cargo.
