Features and Parameters

Using PowerSpec, the Driver Reward feature is easily accessed and configured. Here, the user can enable the feature, set the expected fuel economy and idle time standards, establish threshold limits for progressive speed rewards and select the speed reward mode.

A user might for instance decide that the expected fuel economy and idle percentage standards should be 6.5 MPG and 25% respectively. At this level, it might be decided that no additional speed rewards should be given through either the Road Speed Governor and/or Cruise Control. Driver performance that exceeds these standard values can be rewarded with increased maximum speed levels delivered through the Road Speed Governor and/or cruise control.

In addition, desirable driving behavior can also be rewarded with the realization of an earlier transition to higher torque output on those engines equipped with Electronic SmartTorque. Driver performance that fails to meet the standards imposed, may be penalized through a reduced maximum speed permitted by theRoadSpeed Governor and/or Cruise Control, as well as a longer transition to higher torque for the ESP equipped engines.

It is possible for the Cruise Control maximum speed to exceed Road Speed Governor maximum speed. This situation provides greater incentive for the driver to stay in Cruise Control for longer periods of operation.

Driver Reward Enable
Choose this feature if the benefits of the Driver Reward feature are desired.

Global Maximum Vehicle Speed
Although the Road Speed Governor will limit the maximum speed of the vehicle, it is possible for the limit to be exceeded due to the provision of additional speed rewards delivered by the Driver Reward feature. For instance, if the Road Speed Governor maximum vehicle speed is set at 65 MPH and the Driver Reward feature is providing the operator with an additional 3 MPH, the maximum vehicle speed that can be attained would be 68 MPH. The Global Maximum Vehicle Speed is the maximum speed the vehicle may attain, no matter what additional speed rewards the Driver Reward feature may be providing therefore it is critical to understand the relationship between global speed and current speed settings.

Configuring Driver Reward
Configuring Driver Reward is accomplished in two stages, first setting company fuel economy and idle time standards, and then setting Driver Reward options and levels.

Setting Company Fuel Economy and Idle Time Standards
In order to determine specific Driver Rewards, it is necessary to set performance goals and define values for "Best", "Good" and "Expected" fuel economy and idle standards.

Fuel Economy Standards
Driver Reward Expected Fuel Economy Standard
Determine a fuel economy standard, in terms of miles per gallon, that drivers can be reasonably expected to achieve. The "expected" fuel economy standard can be set at any value between from 0 MPG to 50 mpg.

Driver Reward Good Fuel Economy Standard
Determine a fuel economy standard, in terms of miles per gallon, that is equal to or greater than the already determined "expected" fuel economy standard. The "good" fuel economy standard can be set at any value from 0 MPG to 50 MPG but must be equal to or greater than the "expected" fuel economy standard.

Driver Reward Best Fuel Economy Standard
Determine an optimal fuel economy standard, in terms of miles per gallon, that is equal to or greater than both the "expected" and "good" fuel economy standards. The "best" fuel economy standard can be set at any value from 0 to 50 mpg but must be equal to or greater than both the "expected" and "good" fuel economy standards.

Idle Standards

Driver Reward Expected Idle Standard
Determine a standard of time spent with engine at idle, in terms of percentage of overall trip time, that drivers can be reasonably expected to achieve. The "expected" idle standard can be set at any value between 0 and 100%.

Driver Reward Good Idle Standard
Determine a standard of time spent at idle, in terms of percentage of overall trip time, that is equal to or better than the already determined "expected" idle standard. The "good" idle standard can be set at any value between 0 and 100% but must be equal to or greater than the "expected" idle standard.

Driver Reward Best Idle Standard
Determine an optimal standard of time spent at idle, in terms of percentage of overall trip time, that is equal to or better than both the "expected" and "good" idle standards. The "best" idle standard can be set at any value between 0 and 100% but must be equal to or greater than the "good" and "expected" standards.

Reward Modes – Feature
When the driver meets the determined criteria in  both  the time spent at idle  and  fuel economy standards they can be given speed rewards provided by the Road Speed Governor, Cruise Control or both. Select the speed reward mode that best meets your requirements.

Setting Driver Reward Options and Levels
Drivers who achieve the programmed company fuel economy and time spent at idle standards can be rewarded with speed rewards and/or, for those vehicles equipped with SmartTorque, an earlier transition to higher torque. Drivers who do not achieve the programmed company fuel economy and time spent at idle standards, can be penalized in terms of reduced maximum vehicle speed and/or a longer transition to high torque if the vehicle is equipped with SmartTorque.

Driver Reward Speed Reward Mode
Drivers who achieve the programmed company fuel economy and time spent at idle standards can be rewarded with speed rewards. Drivers who do not achieve the programmed company fuel economy and time spent at idle standards, can be penalized in terms of reduced maximum vehicle speed. This parameter controls whether the speed reward/penalty will affect the maximum speed for Road Speed Governor, Cruise Control, or both.

Driver Reward Expected Speed Reward
Select an additional speed value, in terms of miles per hour greater than the governed maximum speed, that will be available to the driver once the "expected" company fuel economy and idle standards are achieved. Selectable 'expected' speed reward ranges from -20 MPH below maximum vehicle speed to +20 mph above.

Driver Reward Good Speed Reward
Select an additional speed value, in terms of miles per hour greater than governed maximum speed and also greater than the 'expected' speed reward, that will be available to the driver once the 'good' company fuel economy and idle standards are achieved. Selectable "good" speed reward ranges from -20 mph below governed maximum vehicle speed to +20 mph above.

Driver Reward Best Speed Reward
Select an additional speed value, in terms of miles per hour greater than governed maximum speed and also greater than the "expected" and "good" speed rewards, that will be available to the driver once the "best" company fuel economy and idle standards are achieved. Selectable "best" speed reward ranges from -20 mph below maximum vehicle speed to +20 mph above.

Driver Reward Penalty Speed
Select a penalty speed value, in terms of miles per hour less than governed maximum speed, that will limit the driver should the "expected" company fuel economy and idle standards not be met. Selectable penalty speed ranges from -20 mph below maximum vehicle speed to +20 mph above.

Resetting Driver Reward Logs
Driver Reward monitors and analyzes the drivers trip fuel economy and trip idle time at regular intervals, providing the appropriate speed rewards or penalties once the selected company threshold standards are met. As the driver performance data accumulates over the course of a trip, the program averages the information and updates the driver reward level. This accumulation and averaging of trip information will continue until the Driver Reward Logs are reset.

Resetting of the Driver Reward logs is accomplished when Trip Information is reset using Cummins PowerSpec.
