Toyota Schedules Unveiling of Fourth-Gen Self-Driving Prototype at CES 2019

Named P4, the prototype is built on the Lexus LS 500h.


Toyota plans to continue last year’s streak of revealing a self driving prototype at the International Consumer Electronics Show 2019. The third generation concept was unveiled at the 2018 CES, and now the company will display the fourth-gen self-driving prototype in Las Vegas.

Named P4, the prototype is built on the Lexus LS 500h and differs from the third generation example with two additional cameras aiming to improve the car’s awareness of objects to the sides as well as two latest imaging sensors aimed at the front and rear of the vehicle. The radar system in the fourth-gen self-driving prototype has been improved as well and enhances close range detection around the car. The LIDAR sensing system has eight scanning heads, also available in the third generation model, capable of seeing up to 660 feet all around. This eliminates any blind spots.

The P4 is equipped with an updated powerful computing system that works to read the data input and then commands the car accordingly.

Toyota aims to provide its customers with two autonomous driving versions; the Chauffeur system is completely self-driving and the Guardian system allows drivers to drive the car as per their liking but overrides and takes over in case of a dangerous situation.


With further technological advancements, Toyota plans to offer fully autonomous driving cars for everyday users to ride-hailing fleets. In this regard, Toyota’s mobility company Monet will start an automated delivery service by next year. The service will employ autonomous Toyota e-Palette, which was displayed as a shuttle bus concept at the 2018 CES.
