BCM a computer component, or a control module for a control body of the motor controls and operates all the electronic devices in the vehicle. Before the use of electronic devices in cars and trucks, several devices in a vehicle are individually of each electrical components for each managed. All components were separated by different modules - a module for the air conditioning, a module for interior lighting, a module for the door locks, etc. The advent of electronic components in vehicles rented used or the design of the BCM control module body that manages together the individual modules in a system. This led to a unified operation of all modules and components, which makes it easier to manage for the production and troubleshooting performed.
PCM module or powertrain control module and the ECM or engine control module (ECM Mack and Chevy ECM) - ECU engine control unit is also known by two other names. Creates and manages electronic control unit - the amount of fuel, ignition timing and other parameters of the engine needed to run the engine. This is done by evaluating values of the multi-dimensional characteristic diagrams or LUT. The thus obtained values as the engine rotational speed, etc. are. By the signals from sensors, which calculates the power equipment to monitor values Before ECU, sensors and actuators, pneumatic and mechanical and air / fuel mixture, ignition timing and idle speed control.
Then there is another device called TCM or Transmission Control Module. It controls modern electronic automatic transmission with vehicle sensors and the data presented by the engine, for example, the control unit calculates, Truck and ECU when to change gear for optimum performance and fuel and as ride quality.
The late 1980s saw the movement purely electronic automatic transmission with electronic control hydromechanical controls. Since then, the development of motor vehicles has continued to develop and we make today, the result of many stages of development is electronic control automatic transmission. The most important element of these control units transmission solenoids.
The engine control unit, eg Dodge Truck ECU and ECU, is one of the best and most powerful computers of most vehicles for this motor control is the CPU-intensive tasks on the car. The control system continuously monitors used as a known closed-loop control of the ECU which outputs a system - for controlling access to a system, while the handling of fuel emissions of the engine, a lot of other parameters.
The temperature of the cooling liquid the amount of oxygen in the exhaust gas - the ECU after the collection of data from dozens of different sensors, all know. He makes millions of calculations per second - a review of the values in the tables, calculating the results of long equations to choose the best ignition timing and decide how long the injector stays open. Finally, the ECU makes all these activities that the issue of the best cars with lower emissions.
A final ECU / ECM / PCM usually contains a 32-bit and 40-MHz processor. Although much less than the 500 -. 1000 MHz processor you have in your PC, but only the view that the processor car runs much more efficiently, "code" of a PC ECU takes less than a megabyte (MB) RAM running average "code". When comparing an ECU for PC, PC has about 2000 times the amount of ECU program.
In short, the ECM / ECU uses computer-controlled fuel ignition systems for three main reasons:
- Consumer Security
- Save Fuel
- Reduce the production of EPA regulated byproducts
