18.0 Driver Reward
Overview
The Driver Reward feature is designed to improve fuel economy by providing
incentive for drivers to meet customer-defined goals for fuel economy and idle time.
The vehicle speed limit may be lowered when goals are not met, or increased to
reward drivers for meeting the goals.
Note: The Driver Reward feature is only available vehicles equipped with
PACCAR MX engines manufactured after June 2015, and is not compatible
with vehicles equipped with early model year 2015 or prior engines.
Standard Feature


Feature Options

Fuel Economy Evaluation

Idle Time Evaluation
The Driver Reward feature provides the driver with increased vehicle speed for
meeting customer-defined fuel consumption and idle time goals. The customer has
the option of evaluating driver performance based on Fuel Economy, Idle Time
Percentage, or both.
Driver Reward Offset Mode ( N219 ) may also be configured to
apply vehicle speed rewards to the cruise control vehicle speed limit, the accelerator
pedal vehicle speed limit, or both.
The Fuel Economy option allows the engine to monitor and compare actual fuel
economy to
Fuel Efficiency Expected Threshold ( N232 ) , which is the threshold at
which neither a reward nor penalty will be imposed on the driver. The Driver Reward
Maximum Bonus ( N224 ) will be applied if the measured fuel economy is greater than
or equal to Fuel Efficiency Bonus Threshold ( N231 ) . The Driver Reward Maximum
Penalty ( N227 ) will be applied if the measured fuel economy is less than or equal to
Fuel Efficiency Penalty Threshold ( N233 ) . As the driver improves the measured fuel
economy, the maximum vehicle speed will increase with the driver’s performance,
until the
Driver Reward Maximum Bonus ( N224 ) has been reached. As the driver
decreases the measured fuel economy, the vehicle speed penalty will gradually
increase with the driver’s performance, until the
Driver Reward Maximum Penalty
( N227 ) has been reached.
The Percent Idle Time option allows the engine to monitor the percentage of engine
idle time and compare it to
Idle Time Expected Threshold ( N236 ) , which is the
threshold at which neither a reward nor penalty will be imposed on the driver. The
Driver Reward Maximum Bonus ( N224 ) will be applied if the recorded percentage of
idle time is less than or equal to Idle Time Bonus Threshold ( N235 ) . The Driver
Reward Maximum Penalty ( N227 ) will be applied if the recorded percentage of idle
time is greater than or equal to Idle Time Penalty Threshold ( N237 ) . As the driver
decreases the recorded percentage of idle time, the maximum vehicle speed will
increase until the
Driver Reward Maximum Bonus ( N224 ) has been reached. As the
driver decreases the recorded percentage of idle time, the vehicle speed penalty will
gradually increase until the
Driver Reward Maximum Penalty ( N227 ) has been
reached.
