Discover Detroit intelligent Powertrain Management (IPM)

Predictive Acceleration

• Occurs when the engine increases to full power in order to exceed the desired speed prior to a steep ascent.

• Helps compensate for ascent time in predictive acceleration mode.

• The predictive acceleration logic will not allow the vehicle to fuel above the Road Speed Limit value.

• Predictive acceleration is the only IPM mode that fuels above the set cruise speed.

Crest Coast - Regular Mode

• The vehicle may get an eCoast event.

• The vehicle may coast downhill in gear depending on the length and severity of the backside grade.

• The vehicle speed is allowed to dip below set cruise speed.

• The vehicle will recover to set speed on the backside of the hill.

Crest Coasting in Steep Mountains

• On steep uphill grades where vehicle speed cannot be maintained under full throttle, IPM will attempt to crest coast even when the speed is below the under speed threshold.

• The vehicle weight will also have an effect on how the coasting modes function.

 Dip Coasting

• This mode occurs when a downhill grade is quickly followed by an uphill grade.

• The vehicle could exceed the over speed threshold to conserve momentum into the next hill under an engine braking event.

Predictive Adaptive Cruise Control

• Predictive Adaptive Cruise Control- Combines Predictive Cruise Control (PCC) with Adaptive Cruise Control (ACC) to better use kinetic energy and minimize brake usage when following a vehicle. 

• IPM will increase the distance between the vehicles to enable longer and fuel efficient coast or eCoast.

• When approaching another vehicle (docking), IPM will decide if eCoast or engine brake is needed to avoid ACC interference.

Engine Load Balancing

• The engine will hold constant torque over small, subtle grades that drivers may think are flat to reduce unnecessary engine load.

• Engine Load Balancing will allow the vehicle speed to fluctuate (within the upper and lower limits) to reduce unnecessary engine load.

• Similar to a larger hill, the truck would then pick up the lost speed by coasting or eCoasting on the downside of the subtle grade.

Improved Map Coverage

• IPM6 covers 600,000 more road slope miles than IPM4, and of existing major highways and interstates it has increased by 35%.

• Overall mileage increased from 255,854 miles to 903,512 miles
