The GRIP (Governor to Reduce Idle and Pollution) Idle Management System has been created to manage the time that a vehicle spends running in idle. The system is automated, the operator does not need to turn on or engage the system. Once the vehicle is in park or neutral and all system safety interlocks are in place, the system will automatically shut the engine off, keeping the ignition in the run position. The GRIP system works in conjunction with the vehicle’s CAN (Controller Area Network). It receives real time data on the vehicle’s functions including engine revolutions, transmission position, outside temperature, ignition positions and coolant temperature, to name a few. Other data required by the GRIP system is received through sensors added when the system is installed in the vehicle. The controller of the system then makes decisions based on the information it receives allowing it to start and stop the engine of the vehicle as required. Since the GRIP system monitors batteries and auxiliary optional equipment, it allows the operator to perform all tasks as usual and keeps the vehicle operating experience practically the same. The only difference being that the vehicle will be shut down for unnecessary idle without compromising the operator’s ability to do their job, their comfort or their safety.

  1. The system will only function when the vehicle is in Park or Neutral and is not moving. The system must maintain communication with the vehicle CAN network in order to function, otherwise the vehicle stays operating as normal.
  2. The Operator Screen will only illuminate when the vehicle is in Park or Neutral for distraction free driving.
  3. If the hood is opened for service, the GRIP system will not start the engine automatically. The engine can still be started or shut down with the key manually but all auto functions are disabled.
  4. When the GRIP system is in operation and the engine shuts down, the system controls the key position back to the “RUN” position so that the airbags, windshield wipers, lights, and climate control systems are all still functioning.
  5. While the GRIP system is in operation, the system provides an accessory power signal to additional equipment so lights, sirens, and radios all stay operational while the engine is turned off.
  6. The system has an alarm signal that can be used to provide a warning light, horn or audible alarm for operators, workers and their surroundings to warn when the engine is about to start or shut down 
  7. On vehicles with manual transmissions, the system will monitor the neutral switch and only allow the engine to start while the transmission is in neutral. As some manufactures allow their vehicles to start while the transmission is in gear. This will improve the safety of all vehicle.

  1. Settings and Options: The GRIP system has many features and functions that can be used for nearly every application. All these features and functions can be setup and customised to the vehicle’s application, by using the GRIP Service Tool.
  2. Climate Monitoring: The system is designed to monitor the temperature of the vehicle cab and provide heating or cooling by either starting the engine or using devices such as coolant pumps, fuel fired heaters or DC air conditioning systems, to run while the vehicle engine is off.
  3. Battery Monitoring: Typically, it is necessary to add additional batteries to provide the required power to operate all the additional equipment that is added to the vehicle and to operate the vehicle itself. The system monitors the batteries on the vehicle and starts the engine as necessary to keep those batteries at a ready state of charge.
  4. If the optional Current Sensor is used, the engine will monitor the current returning to the batteries so the engine runs enough time to replenish the batteries.
  5. The Current Sensor can also be used to monitor a high load, such as a Power Inverter. The system will keep the engine running as long as that load exists instead of starting and stopping the vehicle frequently.
  6. The system will monitor the vehicle battery condition, such as when the battery drops in voltage when the system shuts the engine off, signaling a poor battery condition.
  7. If the feature is enabled, the system can monitor the air pressure on vehicles equipped with air brakes so that the system can remain full.
  8. Operator Control: The operator can have as little or as much control of the system as you choose. These settings can be manipulated using the Service Tool upon set up and installation.
  9. Configurable I/O: There are several inputs and outputs on the controller that can be utilized to add additional functions to the system. Using the Service Tool, you can utilize the GRIP controller to manage other components.
  10. The system is equipped with a Safe Mode option that allows wider parameters to be set to maintain a vehicle in a stand by situation. Certain parameters can be disabled during this mode as they are not required to be monitored. This will keep the vehicle ready to respond when operators are not required in the vehicle for long periods.
  11. If shore power is available, the system can monitor the shore power connection, displaying it on the screen. The system will prevent the truck engine from starting  with the cord attached.
  12. The system can control the high idle, if available on the vehicle, so that additional devices need not be installed and this will help maintain climate as well as battery levels by raising the rpm when the engine is running and allows the system to shut down if it doesn’t need to be running. 
  13. The vehicle engine can be started for low coolant temperature to maintain engine temperature. It can also be allowed to continue running if the coolant temperature is not high enough upon start up.
  14. The system can control a fuel operated heater manually or by using one of two schedulers to heat the cab, fuel, and hydraulics for winter operation to reduce hydraulic pump failures and improve personnel efficiency getting them on the job faster.

  1. The Anti-Theft Feature allows the operator to leave the vehicle secure by press a button either on the GRIP Operator Screen or by using the normal keypad from the lighting system and remove the keys. They can then lock the vehicle using the key.  The system will continue to monitor the vehicle for battery and climate while they are away from the vehicle. When they return, they simply place the key in the ignition, turn it to “Run” or “Start” depending on whether the vehicle is running, and go. On vehicles with just a standard key, this feature is included with the kit, otherwise additional hardware may be required.

  1. The system collects information accumulatively over the life of the vehicle. From the time of the installation, it records the usage or “Life” of the vehicle every time the key is turned to the “Run” position.
  2. It records the overall Vehicle Operations such as how much time the vehicle has been driving, static in Park and Neutral or how much time the vehicle has been off in Monitoring mode with no requirement for climate or battery.
  3. It records the time that additional equipment such as a coolant pump, fuel fired heater or DC air conditioning operates while the vehicle engine is off.
  4. It records the time that the vehicle has been idling for any reason whether it’s for climate, low battery or any of the safety starting features such as door start or humidity.
  5. It records possible override conditions such as the brake pedal being held while the vehicle is in drive or the park brake being engaged while the vehicle is in drive.
  6. It records the process counts such as how many times it started for door open or seat belt.
  7. It records the time that the PTO has been engaged to compare how much of the operation was actually in PTO mode vs stand by and driving.
  8. It records the fuel consumption data. It will provide the overall average of fuel consumed during the vehicle operation at idle to provide real fuel consumption data straight from the vehicle.
  9. By using our Data Analysis Tool, you can take that data and turn it into realized savings information and emissions reduction.  You can use that data to determine what additional equipment or change in behavior is required to achieve better results.


The GRIP has been designed to be non-invasive and with ease of installation in mind. The components for the system are easily mounted and the harnesses are clearly marked for locations. The GRIP incorporates a plug and play connection method with only one connection needing to be cut and connected into the ignition.

The information collected by the system will allow fleet managers and supervisors to observe the idling tendencies for their fleet in order to make educated decisions on program settings in order to further benefit their fleet. All of these adjustments can be made by a fleet supervisor or manager through the programming screen of the GRIP system. The system can also provide insight for how the vehicle is being used and the duty cycles of the vehicles. In many cases the data can help the fleet make decisions of whether certain vehicles are not used enough and therefore reduce the number of vehicles in the fleet.
