Lexus has announced its newest addition to the lineup, the 2019 UX. It offers the brand’s innovative luxury and safety in a package that combines new design elements and powertrains.

Some of the connected features in the car include:

  • Lexus Enform allows linking of smartphone apps.
  • Apple CarPlay® allows easy iPhone integration using the vehicle’s display, expanding multimedia capability. CarPlay supports other apps on your iPhone — like your favorite audio, messaging, and voice apps as well as new third-party app extensions.
  • A 4GB WiFi Hotspot allows a user device to become an internet access point.
  • Instant Replay allows the user to capture SiriusXM® content for later playback.
  • Dynamic Voice Recognition allows natural voice commands.
  • USB Video and RealMedia video formats are supported.
  • Favorite Genre for FM and SiriusXM® allow the user to select a preferred music genre to discover new stations.
  • The available Lexus Navigation system features the brand’s latest graphical user interface for greatest ease of use and access to features. In the US, Hybrid Navigation combines onboard map data with the latest satellite information.

Predictive Eco Drive Control

The UX 250h debuts Predictive Eco Drive Control, a system that, coupling with the navigation system, learns driving habits, predicts the expected roadway ahead and analyzes real-time traffic reports to optimize charging and discharging of the hybrid battery.

The more miles 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

Also operational with navigation, 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 to be recovered and recharged into the hybrid battery. The system can provide deceleration support up to about 1,000 feet ahead of the vehicle.

Predictive State of Charge (SOC)

Predictive State of Charge (SOC) control for the hybrid battery is a 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 6 miles ahead to optimize the conditions under which it can regenerate energy, earning power for future driving.

Here is a real-world example of its benefits: On a long, downhill stretch of road, with the hybrid battery storing a large amount of energy, a full charge could be reached partway down the hill. Beyond that point, any additional regenerated energy cannot be recovered, effectively wasting it. Instead, Downhill SOC control uses gradient information from map data to calculate when a long downhill stretch of road lies ahead and then actively relies on battery-only driving to reduce the level of battery charge prior to that regeneration opportunity. Fuel efficiency improves since the level of battery charging gained on that downhill section is increased.

Conversely, in stop-and-go traffic or low-speed driving, the electric motor is used more, reducing the hybrid battery’s charge. In this scenario, Congestion SOC control uses traffic information from the navigation system to determine if there is any congestion on the planned route. If so, it actively charges the hybrid battery before reaching the congested area, reducing the need of forced engine start to charge the battery in those conditions.

Safety technology and Driver Assist

The standard Lexus Safety System+ 2.0 includes:

The Pre-Collision System uses an integrated forward-facing camera and grille-mounted radar system designed to help mitigate or avoid a frontal collision. LSS+ 2.0 enhances this system with the addition of low-light detection for pedestrians, plus daytime detection of bicycles. Under certain conditions, if the Pre-Collision System determines that the possibility of a frontal collision with a pedestrian or bicyclist is high, it prompts the driver to take evasive action and brake by using an audio and visual alert. If the driver notices the hazard and brakes, the system may use Brake Assist to provide additional braking force.

If the driver does not brake in a set time and the system determines that the risk of collision with a pedestrian or bicycle is extremely high, the system may automatically apply the brakes, reducing speed to help mitigate the impact or avoid the collision entirely if possible.

Dynamic Radar Cruise Control uses a front grille-mounted radar and a forward-facing camera to detect vehicles ahead and automatically adjust the vehicle’s speed to help maintain a pre-set distance. DRCC operates between 0-110 mph but must be initiated at speeds above 19 mph.

Lane Departure Alert is designed to use the vehicle’s forward-facing camera to detect lane departure when traveling on relatively straight roads with clear lane markings, road edges or curbs when DRCC is operating and when two visible lane lines are detected. The system’s current operating status is indicated through colored lane marking illustrations on the vehicle’s Multi-Information Display (MID). If Lane Departure Alert determines that the vehicle is starting to unintentionally deviate from its visibly marked lane, the system alerts the driver with an audio and visual alert. In addition to the alert function, all UX vehicles are equipped with Electronic Power Steering (EPS) also include Steering Assist. When this functionality is enabled and Lane Departure Alert senses that the vehicle is unintentionally drifting from its lane, the system may automatically make small corrective steering inputs to help the driver keep the vehicle in its lane.

Lane Tracing Assist (LTA) is designed to work with Dynamic Radar Cruise Control to keep the vehicle centered in its visibly marked lane and preemptively avoid unintended lane departures. LTA uses a forward-facing camera to monitor lane markings – as well as the path of the vehicle ahead, if needed – and is designed to automatically make constant steering inputs to help keep the vehicle centered in its lane. LTA does require the driver’s hands to remain on the steering wheel.

Road Sign Assist is designed to read certain traffic signs and display them on the vehicle’s Multi-Information Display (MID). The system can read Speed Limit, Stop, Yield, and Do Not Enter signs. Intelligent High Beam is a safety system designed to help the driver see more clearly at night – while reducing glare for other drivers. By using high beams more frequently, the system may allow earlier detection of pedestrians and obstacles.

When activated, Intelligent High Beam is designed to rely on an in-vehicle camera to help detect the headlights of oncoming vehicles and taillights of preceding vehicles, then automatically toggle between high and low beams.

Parking Support Alert(PSA)

Other available safety systems include Parking Support Alert(PSA) and Parking Support Brake (PSB). PSA can detect crossing vehicles from the sides and static vehicles in front of or behind the UX when parking over a broader range of conditions than previous clearance sonar or rear cross traffic systems, and uses digital camera images on the center display along with audibles to alert the driver to potential risks.

The PSB system adds active drive force (throttle) and braking control to audible and visual warnings to reduce the possibility of contact with moving objects ahead or behind the UX when parking.
