Frequently Asked Questions

How Does iNTELLIDRIVE work?

iNTELLIDRIVE works by capturing energy that is normally wasted through friction brakes and turned into heat and converting it into stored energy that resides onboard the vehicle. When the operator goes to accelerate the vehicle, the stored energy is release back to the driveline, where it assists the engine in accelerating the vehicle.

How is Energy Captured, exactly?

We install a gearbox between the transmission and rear differential of the vehicle, along with a bank of hydraulic accumulators along the frame rail. The gearbox is connected to a hydraulic pump that spins when the driveline is turning. This pump is used as both a pump and a motor. When the operator is attempting to slow the vehicle down, the pump is being turned and is pumping oil against high pressure into the bank of accumulators. The oil is stored in the accumulators until the driver presses on the accelerator pedal, when it is then released back to the pump, which is now acting as a motor. This creates an assisting torque that is applied to the rear wheels, along with the torque that comes from the traditional engine.

What Benefits Do I Get From Capturing Braking Energy?

There are several benefits that come with capturing the normally wasted energy from braking a heavy commercial vehicle. Fuel savings, less brake wear/changes, lower emissions, longer life from engine/transmission, higher productivity, less driver fatigue, etc. are all positive changes that can be expected from iNTELLIDRIVE.

What Kind of Return on Investment Can I Expect?

Typically, SES customers experience around a 2 year ROI, based on a variety of factors. This normally would include fuel savings, brake wear savings, reasonable estimates on increased productivity and reduced engine and transmission wear.

How is iNTELLIDRIVE Good for the Environment?

iNTELLIDRIVE helps to reduce the load put on the engine. In turn, this allows the engine to burn less fuel. It's like the vehicle is always driving downhill, at least that is what the engine feels like. The reduction in fuel consumption correlates to a reduction in carbon emissions, but it is typically not a linear correlation.
 
Diesel engines emit a much higher carbon gas when they first become under load, but the vehicle doesn't yet have any momentum. Since the iNTELLIDRIVE helps to get the vehicle moving initially, this brings the total time the engine is in that 'high pollution' zone down significantly, and can often lead to emissions reductions of up to 90% overall.

How is iNTELLIDRIVE different from other hybrid technologies?

The iNTELLIDRIVE was designed with efficient power density and value to the customer being the two most important factors. First, the iNTELLIDRIVE utilizes hydraulic technology as opposed to electric or others because it has the power density and capacity to handle large heavy duty commercial vehicles. If an electric hybrid were to be used on these vehicles, the batteries would be so large that the payload capacity would be compromised.
 
Secondly, the system is retrofitable and parallel to the traditional drivetrain. This means that an existing fleet of vehicles can be upgraded, without the need to order new vehicles. A system can also be recycled to another vehicle in the case of a truck being retired.The iNTELLIDRIVE is also 'parallel', meaning that the standard drive train of the vehicle remains intact, with the system being run in parallel to it. This allows the iNTELLIDRIVE to be decoupled and the vehicle can run as it normally would in the event of a system malfunction.

Is a Vehicle with an iNTELLIDRIVE System Hard to Drive?

While there are some minor modifications required to drive a vehicle equipped with a system most efficiently, driving with iNTELLIDRIVE is very similar to regular driving of the vehicle. Refer to the Driver's Manual on the iNTELLIDRIVE page for more details. The biggest difference is in the brake pedal, as it gets split up into 2 'zones', with the first being hydraulic braking only, and being followed with hydraulic + foundation braking.

What Kind of Route is Best for an iNTELLIDRIVE Equipped Vehicle?

The iNTELLIDRIVE system will have the most impact on a heavy vehicle that makes numerous successive stop-start cycles during its daily route. Refuse collection routes exhibit the traits that are especially suitable for application of the iNTELLIDRIVE.

Is There A Lot Of Extra Maintenance Required?

The iNTELLIDRIVE system was designed to require very little regular maintenance by the end customer. There are simple daily tasks such as checking oil level and ensuring cooling fans are clear of debris. There are also preventative maintenance jobs that should be contemplated every 3-6 months. Check the Service Manual located on the iNTELLIDRIVE page for more details.

What Happens If There Is A Problem With iNTELLIDRIVE?

The iNTELLIDRIVE control system includes lots of 'self-protection' logic to help make sure that no catastrophic failures will occur. Occasionally, a problem will arise and a fault will be triggered by the control system. An alert on the screen will inform the driver of the problem and the iNTELLIDRIVE system will disengage from the drive train. The driver can then continue on his way, and maintenance on the system can be scheduled when it's convenient to the user.
