CAN-BUS controllers

Vehicle operation is controlled via CAN-bus.

We have decreased expenses on a satellite-based monitoring by more than twice.

A new monitoring system was developed and introduced to meet all customer`s requirements. At that the system is more advantageous of those used before.

Fleet park owner faces financial losses in case of increased mileage, operation for private gains, violation of operational modes. Satellite monitoring system is developed to avoid such losses and to control vehicle operation and state. The system presents a module which reads data from CAN-bus and transmits it to a host computer.

However two hurdles could be faced by standard satellite monitoring system:

  • 1. Lack of flexibility.Only basic parameters could be kept and no possibilities to customize to specific needs
  • 2. Costly. If on Mercedes such a monitoring system may be a significant sum of money per one vehicle unit. Having a large fleet park, we may see a sizable loss.

We have reached an outcome deprived such drawbacks

Client

  • One of the larges cargo carriers
  • Fleet park counts 845 vehicle units
  • More than 100 000 journeys  a year
  • Cargo transportation geography – entire territory of Russian Federation

What did we do for a customer?

The customer used to have satellite monitoring system provided by Mercedes, Renault and Scania

  1. We replaced an old monitoring system with Wialon.  It appears more flexible and compatible with other  GPS devices.
  2. We connected to CAN-bus  and decoded the required data
  3. Designed a new firmware for GPS tracker and reinstalled on a vehicle.

Hence  data from tracker are transmitted to a host computer in  real time.

Software opens a friendly interface

It is easy to access any data and graphics.

16 monitoring parameters

The most essential are below:

Fuel consumption. Large-sized fleet parks uses fuel card system. Dishonest drivers may make petrol frauds, fuel other vehicles and embezzle money.

We have developed a tool that tracks fuel transactions based on an automotive comparison of pumped into and consumed petrol indicators. The fuel-management system records and processes fueling data associated with a driver ID and compares data from operator`s private account and those of actual fuel consumption (based on a sensor in a car tank).

Violation of speed limits

Maximum allowable speed –  82 km\h. In case of overspeed, the system  notifies an operator

Number of stops and slowdowns

This parameter gives a clear understanding of a driver professionalism

Distance pacing Cruise- control

Excessive use of cruise control may lead to an accident or a technical malfunction.

Vehicle average weight

The parameter identifies  if a truck was empty or not.  Vehicles are equipped with axle load sensors and data are transmitted to a satellite monitoring system device.

Engine breaking and service breaking

Alone engine breaking may red-flag that a driver spares a fuel or pumps it out. In case of only service breaking  a driver is assumed not to be careful and there is a risk of accident.

Engine rpm

Drive at increased rpm  leads to a fast engine wear. We decoded CAN-bus parameters and now  these parameters  are reported in a general monitoring system.

Freewheeling

Freewheeling saves fuel but often is a reason of accidents, especially in winter

Idle run

Sensors detect  engine run at idle.  The longer it goes, the  higher fuel consumption and vehicle wear are.

Hard breaking

Hard breakings  increases risks of accidents.  Data come from an accelerometer  that  records breakings and slowdowns.

In upshot:

  • Run period – 3 months
  • A complex solution to satisfy fully  customer`s needs
  • Possibility to integrate additional modules
  • Decrease of line rental fees on satellite monitoring – from 13 USD to 7 USD a month
  • Costs – cutting – several dozens of  thousands USD
