Featured on the UD Quester, the Fuel Coaching System is a powerful real-time tool, which assists drivers in improving their eco-driving skills. Integrated with the Engine Management System, this on-board system guides the driver in operating the UD Quester more efficiently. It takes into account various factors that are out of the driver’s control, such as payload, weather, wind, temperature, topography, seasonal variations, etc., to make the most of each drop of fuel.
A real-time coach
Every second on the road, the Fuel Coaching System guides the driver with icons displayed in real time on the dashboard, assists him to run the engine in its most efficient RPM range, or its “sweet spot”.
Reading the icons
The Fuel Coaching System displays the guiding icons on the top right part of driver information display, continuously giving feedback about how to drive in the engine’s most fuel-efficient zone, its sweet spot. The Fuel Coaching System will indicate when and how much throttle to apply and whether to upshift or downshift.
The double thumbs-up icon means that the engine is operating in the most efficient range.
The single thumbs-up icon means that the engine is operating in a less efficient area of the sweet spot.
The RPM up icon indicates an increase in engine speed is required by down shifting or applying more throttle.
The RPM down icon indicates a decrease in engine speed is required by up shifting or applying less throttle.
The pedal up icon means apply less throttle.
The pedal down icon means apply more throttle.
These icons will only be displayed when the speed exceeds 30 kilometers per hour or 10 kilometers per hour in certain circumstances.
Editing reports
A UD powerful tool to improve eco-driving skills
The Fuel Coaching System shows current trip performance data in the instrument cluster’s driver information display and stores the data in the control unit.
Providing a summary of driving habits over a journey, a period of time, or a certain distance, The UD Quester gives clear information, helping the driver to compare his current and previous performance, and evaluating the progress of his eco-driving skills.
It sums up the amount of fuel consumed in the sweet spot and compares it to the total amount of fuel consumed over the same distance. This figure is represented as a percentage under the sweet spot symbol. The higher the number, or percentage, the better. It also measures fuel consumption (in kilometers per liter) over the entire trip. The percentage is not dependent on the load and the route, meaning that each driver can measure his performance and his improvements, and even compare various journeys.
Data can be stored in three different trip modes:
1) Trip start and stop are recorded by the driver with the help of the RESET button on the cluster
2) Trip start and stop are recorded at an interval of a preset distance set by the owner
3) Trip start and stop are recorded at an interval of a preset time set by the owner
The details of multiple trips with the UD Quester will be stored and can be extracted later for performance analysis with the help of a telematics system or a basic follow-up tool.
Dedicated use of the Fuel Coaching System can result in anywhere from a 5 to 30 percent reduction in fuel consumption, depending on the skill set of the driver.
UD Trucks wishes you a smooth and fuel-efficient trip with the UD Questers!
