GPS control of fuel consumption in a passenger car using an on-board computer (CAN bus)

How to check the fuel consumption of a passenger car?

Our company offers a solution to this problem. We offer an inexpensive and effective solution for fuel control in passenger cars.

The peculiarity of cars is that the standard solutions for the control of fuel consumption that are used in GPS monitoring, such as:

• installation of a fuel level sensor;
  
• installation of a fuel flow meter;

on passenger cars are less efficient in terms of money investment, due to relatively low fuel consumption (compared to trucks and special equipment).

In the illustration:

*FLS - fuel level sensor.

Cost-effective solution for monitoring fuel consumption via CAN bus

Most modern cars have the ability to connect to the on-board computer and read the data on the on-board computer.

The most valuable information is:

• Fuel level - allows you to control fuel fillings, time and volume. The special feature is the float sensor. They tend to wear out over time.
• Fuel consumption - the most valuable and accurate data. The on-board computer calculates the total amount of fuel consumed. Allows achieving an error of up to 2-3% (in case of correct calibration).

Additional readable parameters from the on-board computer:

• vehicle mileage according to odometer data;
  
• engine speed;
• vehicle speed (according to the on-board computer);
• the force of pressing the gas pedal (accelerator), displayed as a percentage used to control aggressive driving;
• total engine running time;
• engine temperature;
• engine load,%;
• engine oil level

Optionally read parameters, depending on the vehicle model:

• axle load, kg;
• AdBLUE liquid level;

What car models are supported?

Go to the catalog of cars and the list of parameters that can be read from the CAN bus of the on-board computer: CAN-bus parameters that are read by GPS tracker.

An example of a report on the fuel consumption of a vehicle based on CAN bus data

*DART is an absolute fuel consumption sensor. This refers to the cumulative consumption for the selected time interval.

Where and how is the GPS tracker connected to the vehicle CAN bus?

Despite the fact that the principle of connection is the same - to read the parameters, you need to connect to 2 wires (CAN-H and CAN-L), the location of these wires is different for each car. Moreover, most cars have multiple CAN buses.

To choose the optimal connection point, contact our company and we will help you resolve the issue of connecting to the car's CAN bus.

Below is an example of a connection point for a Renault Megane 2 vehicle.

The installation process takes up to 1 hour. The connection can be non-contact (without inserting into the CAN bus wires). The reader is attached to the wires, the vehicle warranty remains.

7 advantages of connecting a GPS tracker to the vehicle CAN bus

1. Fuel level control (refueling, fuel draining).
   
2. Accurate control of cumulative consumption (according to the on-board computer).
3. Engine RPM Control - Used to control aggressive driving. The system automatically assigns a rating to drivers who drives aggressively. Prevents premature engine and vehicle failure.
4. Oil level and pressure control - notifies the owner that the oil level has dropped below a critical one, prevents the engine from breaking. This is especially actual for cars that are rented.
5. Engine temperature control. Prevents vehicle breakdown in case of problems with the cooling system.
6. Gas pedal position control. If the driver always pushes the gas to the floor, this leads to increased fuel consumption and uneconomical driving. This parameter is also used to define neat driving experience. The system will give an appropriate rating for this driving style.
7. Total control of the car. Diagnostic information reading system - practically can carry out remote computer diagnostics of a car online. The owner receives maximum information about the current state of the car: the status of the doors, hood, trunk, the need for maintenance, and much more. Data that can be useful in any critical situation.
