Anyone have much info on how Predictive Efficient Drive works? Can you tell it's actually doing something?

 

I found these reports: https://mag.lexus.co.uk/predictive-drive-system/
https://www.fleetnews.co.uk/news/man...ost-efficiency

I don't tknow if it requires navigation to be on? I'm guessing these systems monitor the vehicle regardless of whether you want them to or not. Could be a good thing in this case.

 

This could be a game-changer, but Lexus doesn't provide much information about it. By using destination entries in the Nav system, the Predictive Efficient Drive (PED) records how you drive based on location, and then increases Regeneration and other features, to optimize the car's performance based on your history and current traffic conditions. This would help someone who takes the same route regularly, such as a commute, and the system would know how much battery you will need, thus how much charging it provides, based on earlier behavior.

I would surmise that you would want to enter your destination in the Nav as often as possible whether you use it or not. This may also explain why some people report better 'mileage' as time goes on. The manual claims it can be turned ON/OFF but doesn't show it's default. The PED activates the "Predictive Deceleration Support" and the "Predictive SOC (State Of Charge) Control" to further refine that data. It is usable only in the mainland USA and applies to your vehicle, "If Equipped". I haven't found it yet.

 

More from the U.K. I presume it applies to the U.S. as well:

How does it work?

With the help of the Lexus Link app, selected Lexus hybrid and plug-in hybrid electric vehicles with embedded navigation systems will be able to learn a driver’s regular routes and driving style, while simultaneously looking ahead via live traffic data to anticipate opportunities to save fuel. More economical driving is automatically and seamlessly achieved by optimising the charging and discharging of the battery on hybrid models, and the use of full-electric or hybrid modes on PHEV vehicles.
Data in the navigation system helps Predictive Efficient Drive identify journey sections where sudden deceleration happens – locations where regenerative braking can automatically be increased to maximise energy recovery. During navigation, when traffic is detected on the route ahead, the system proactively charges the battery to reduce the need for the engine to be used in slow or stop-start traffic. Additionally, the technology analyses upcoming traffic and road conditions, such as up/downhill or urban/motorway sections, and seamlessly adjusts battery charging and discharging for lower fuel consumption.

The smart system becomes increasingly effective the more it is used, so as the number of miles driven increases, so does the volume of data at its disposal; this is then used to make ever more efficient use of the vehicle’s electrified powertrain.

Which Lexus models come with Predictive Efficient Drive technology?

Predictive Efficient Drive made its debut in the latest Lexus NX hybrid and plug-in hybrid models with embedded Lexus Link Pro navigation and is expected to be rolled out to other models in the future.
