The new electric motorcycle Harley Davidson LiveWireintroduce thecellular connectivityandelectronic rider assistfeatures in itsride enhanced systems.
TheLiveWire interfaceshas been designed to allow the owner to create a personalized and fully connected riding experience. Those features include the following:
H-D Connect Cellular Connectivity
The LiveWire motorcycle is equipped with H-DConnect service technologythat provides cellular connectivity that can link a LiveWire owner with their motorcycle through their smart phone using the latest version of thefree Harley-Davidson App. The H-D App is available in the iOS and Android app stores and core functions (turn-by-turn directions, ride planning, dealer and event locations) of the app are included with the free download. H-D Connect transmits key vehicle health information through the H-D App and provides the owner with the reassurance of being able to remotely monitor their motorcycle’s security, including tamper alerts on the H-D App and stolen-vehicle assistance.
The H-D Connect servicewill be offered for aone-year free trial periodafter the purchase of a new LiveWire motorcycle andavailable with a subscription charge following the initial free period. H-D Connect will beavailable beginning in Fall 2019 in the United States, Canada, Puerto Rico and most EU countries. In lateAugust 2020, service will be available in Australia, Brazil, Mexico and Japan. Subscription details can be found onH-D.com/connect.
Motorcycle status:With H-D Connect and the H-D App, the LiveWire motorcycle owner will be able to check keyvehicle health information on the H-D App at any time and from any locationwhere sufficient cellular signal is available. Information available through H-D Connect includeshigh-voltage battery charge status, available range and 12-volt battery charge status. For example, as the LiveWire motorcycle is charging, the owner can check the charge status, including charge level and time to completion, without having to be near the motorcycle.
Tamper alerts and stolen vehicle tracking service:To ensure that an owner’s bike is safe and secure, H-D connect indicates thelocation of the parked motorcycle on a map in the Harley-Davidson App at any timeand in any location where sufficient cellular signal is available.H-D Connect will send an alert to the owner’s phone if the security system is activated because the motorcycle has been bumped or is being tampered with.Another alert will be sent to the owner’s phone if the motorcycle ismoved out of the geo-fenced area,andGPS-enabled stolen-vehicletracking provides peace of mind should the owner need to locate their motorcycle.
Service reminders and notifications: Automated reminders about upcoming vehicle service requirements and other vehicle care notifications will be provided to the rider through the H-D App, which will also offer a Charge Station Location Finder.
Color Touchscreen
A 4.3-inch color TFT touchscreen(thin-film-transistor, a type of liquid-crystal display noted for high image quality and contrast)located above the handlebar offers the rider a wide range of information on a display that’s bright and easy to read. The display unit is tilt-adjustable to afford most riders an optimal viewing angle and the screen brightness adjusts automatically. The touchscreen only functions when the motorcycle is not moving but many of the display options can be changed using the hand control joysticks while riding.
A speedometer, range and high-voltage battery status (percent remaining) are always displayed, as required by motor vehicle regulations.
- The screen displaycan be customized with several rider-selectable “widgets.” Some include:
- A power meterthat indicates how much of the available power is being used as the motorcycle is being ridden
- Ride Mode indicator(displays which mode is active)
- Charging status(showing time remaining to full charge)
- Alert information keyedto the tell-tale warning lights (turn signals, ABS active, Traction Control active, Check Engine/Battery Overheat, etc.)
Active Bluetoothconnection and available functions
The LiveWire motorcycle offers Bluetooth connectivityfor use with a smartphone and a wireless headset through the touchscreen. The rider can listen to music files stored on the smartphone, accept incoming calls, and hear turn-by-turn navigation instructions provided by the Harley-Davidson App. Music file and incoming call information is displayed on the screen. The rider can control music and phone functions with the joystick hand controls.
Tell-tale lights or indicatorsare located on each side of the display frame: Turn signals, high/low beam headlamp, ABS active, traction control active, fault warning.
Reflex Defensive Rider Systems
The LiveWire model is equipped with Reflex Defensive Rider Systems (RDRS),a collection of technology designed tomatch motorcycle performance to available traction during acceleration,deceleration and braking.The systems are designed to aid the rider in controlling the vehicle while accelerating and braking in a straight line or while in a turn. A rider may find the systems most helpful when riding in adverse road conditions and in urgent situations.The systems are electronic and utilize the latest chassis control, electronic brake control and powertrain technology.
Cornering Enhanced Antilock Braking System (C-ABS)
ABS is designed to prevent the wheels from locking under braking and helps the rider maintain control when braking in a straight-line,urgent situation.ABS operates independently on front and rear brakes to keep the wheels rolling and prevent uncontrolled wheel lock. Cornering Enhanced Antilock Braking System (C-ABS) is avariant of ABS that takes into consideration the lean angle of the motorcycle. The brake pressure required to limit wheel slip when cornering is typically lower than the pressure required under straight line operation.Rear-wheel Lift Mitigation utilizes the C-ABS sensors and the six-axis inertial measurement unit (IMU) to manage rear-wheel lift during heavy braking and further balance deceleration and rider control.
Cornering Enhanced Traction Control System (C-TCS)
Traction control is designed to keep the rear wheel from “spinning out” when the motorcycle is accelerating, and enhances rider control and confidence, especially in wet weather.The Cornering Enhanced Traction Control System (C-TCS) is designed to prevent the rear wheel from excessive spinning under accelerationwhen going straight or cornering. C-TCS can improve rider confidence when available traction is compromised by wet weather, a sudden unanticipated change in the surface, or when riding on an unpaved road. The action of C-TCS is also tailored when cornering based on lean angle. Each pre-programed ride mode has a specific level of C-TCS. In the customizable ride modes, the rider can select from three levels of C-TCS intervention. With the exception of Rain mode, the rider can deactivate C-TCS when stopped. C-TCS can be re-activated with the push of a button on the left-hand control when the motorcycle is stopped or underway.
C-TCS is also designed to support Front-Wheel Lift Mitigationto reduce the height and duration of front-wheel lift (wheelie). The height and duration of front-wheel lift is tied to the rider-selected C-TCS mode, with Rain being the most-restrictive and Sport being the least-restrictive. Front-Wheel Lift Mitigation is turned off when C-TCS is turned off.
Drag-Torque Slip Control System (DSCS)
Drag-Torque Slip Control (DSCS) is designed to manage rear-wheel slip and prevent rear-wheel lock due to regenerative braking, which typically occurs when the rider decelerates on wet or slippery road surfaces. DSCS functions at speedsover 10 mph (about 17 kph) and works in concert with the ABS systemto balance motorcycle deceleration and rider control. DSCS is integral to rear wheel ABS performance.
Ride Modes
The LiveWire model offersseven selectable Ride Modes that electronically control the performance characteristics of the motorcycleand the level of electronic intervention. Four of the modes are pre-programmed and three are customizable by the owner. Each Ride Mode consists of a specific combination ofpower(which dictates the maximum rate of acceleration),regeneration(felt as a braking effect when off-throttle),throttle response, andtraction controlsettings.
The rider uses the MODE button on the right-hand controllerto change the active ride mode, and the active mode may be displayed as a widget symbol on the color touchscreen.The rider can change ride modes at any time, while riding the motorcycle or when stopped.
Sport Mode:Delivers the full performance potential of the motorcycle in a direct and precise manner, with full power and the quickest throttle response on tap.Traction control is set to its lowest level of intervention, andregeneration offers a significant off-throttle braking effect. Sport Mode maximizes the rider connection to the motorcycle for a direct and visceral performance riding experience.
Road Mode:Delivers balanced performance with an intuitive blend of technology for daily use, withAnti-lock Braking System (ABS) and Traction Control System (TCS)intervention that offers peace of mind. In Road Mode, the LiveWire motorcycle response will feel more similar to an ICE-powered (Internal Combustion Engine) motorcycle.
Range Mode:Offers a blend of settings that results in smooth and judicious response to throttle input with a high level of regeneration to get the most riding distance out of a battery charge.
Rain Mode:This mode offersrestrained acceleration and limited regeneration with higher levels of electronic intervention to give the rider greater confidence when riding in the rainor when traction is otherwise limited. The Rain Mode is also an appropriate setting for riders to use as they become familiar with an electric motorcycle, andto build riding confidence.
Note:The ridermay choose to turn off the Traction Control System (TCS)when themotorcycle is stopped.When TCS is turned off, it will not be active in Sport, Road or Range Mode.TCS is a default in Rain Mode, however, and will be active whenever Rain Mode is selected. Anti-lock Braking System (ABS) is always active and may not be turned off by the rider.
Custom Modes:With the motorcycle off, the rider can create up tothree Custom Modes, displayed as A, B and C on the touchscreenmode widget. Custom Modes allow the rider to select their own combined preference ofPower, Regeneration, Throttle Response and Traction Controllevels within specific ranges.Power, Regeneration and Throttle Responsecan be adjusted from 0 to 100 percent in 1 percent increments,andTraction Control can be set to Low, Medium or High intervention. So, for example, the rider could create a mode with 100 percent power and throttle response (as is pre-programmed Sport Mode) but with a lower level of Regeneration than is offered in the pre-programmed Sport Mode. The rider can create a Custom Mode tailored to personal preference or for use in special circumstances, such as track days.
