Lexus links hybrid system to sat-nav to boost efficiency

Lexus is rolling out a new technology that will boost the efficiency of its hybrid and plug-in hybrid (PHEV) models.

Predictive Efficient Drive will initially be offered on the Lexus NX and works by analysing driving habits and real-time traffic information to maximise energy recovery and electrified driving.

More economical driving is 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 adjusts battery charging and discharging for lower fuel consumption.  

Lexus says 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 more efficient use of the vehicle’s electrified powertrain. 

Predictive Efficient Drive is expected to be rolled out to other Lexus models in the future.
