Predictive Efficient Drive
Some hybrid drivers enjoy using “hypermiling” techniques to maximize fuel efficiency. The Lexus UX 250h introduces new technologies that take hypermiling to new heights. The UX 250h debuts Predictive Efficient Drive, a Lexus-first system that analyzes driving habits and the expected road and traffic conditions to optimize charging and discharging of the hybrid battery. The more the UX 250h is driven, the more data is gathered to help optimize fuel consumption. (The system can be turned off if desired.)
Predictive Deceleration Support technology uses accumulated knowledge about a driver’s behavior to predict when and where the vehicle is likely to slow down or stop. For example, when the UX approaches a location where the driver has slowed or stopped in the past, and the driver releases the accelerator pedal, Predictive Deceleration Support increases regenerative braking, allowing more efficient energy recovery and recharging of the hybrid battery. The system can provide deceleration support up to about 1,000 feet ahead of the vehicle.
Predictive State of Charge (SOC) control for the hybrid battery is a world-first technology that functions on both downhill roads and in congested traffic. Operating when the UX is following guidance from the navigation system, it will predict the route for a distance of up to about six miles (10km) ahead.
