    FAQs Regarding Body Control Module


      Ans. Our Reference design of the Body Control Module (BCM) supports following features/functionalities:

      1. Mirror Control
      2. Window control
      3. Seat Control
      4. Lamp Load
      5. Washer
      6. Wiper
      7. Solenoid Control
      8. Actuator Control

      Apart from these, data communication between Instrument cluster control and BCM via CAN is also integrated using re-usable components of our BCM reference design.
      Our automotive BCM reference design is also equipped with the feature to read data from the sensors. The information may include pressure, fuel level, vehicle/engine speed and others.

      Ans. Our body control module supports the most widely deployed diagnostics protocol in the new age automobiles; viz; J1939, OBD2 and UDS.

      J1939 can be integrated for commercial vehicle applications while UDS/OBD can be integrated with passenger vehicles.

      Ans. Our codes strictly adhere to the MISRA C 2012 guidelines.
      Body Control Module is one among the gamut of automotive electronic units in new age vehicles. A BCM is essentially an electronic control system that is controlled by a microprocessor.

      Functions such as central door locking, power window, lights, wiper control, seat adjustment, climate control and more are managed by the Automotive BCM solution.

      Additionally, it may also act as a gateway for in-vehicle network interfaces and Bus systems to facilitate interactions with other vehicle control units.

      A typical embedded automotive solution of a Body Control Module has the system architecture similar to any other vehicle ECU solution.

      The components of the same, are as follows:

      1. A Microcontroller, best suited for the use-case/automotive application
      2. Communication Interfaces (CAN, LIN, MOST etc.)
      3. Load Drivers
      4. Diagnostics Services (UDS, J1939, OBDII)
      An Automotive BCM system works on the basis of input received from the input devices (potentiometers, sensors, magnetic pickup etc.) and the output generated by devices like relay and solenoids.

      Between these two, are the algorithms and APIs. that define what the action would be and how will it be performed.

      An example will make things more clear. Let’s consider the example of remote unlocking of the door.

      • When a user presses the key on a door lock remote, the RFID (Radio Frequency Identification) module of the BCM receives a signal. It will then verify the frequency of the received signal with the frequency stored in the ECU memory.
      • If the frequencies match, it will send the signal to the central locking relay which will perform the required mechanical action to unlock the door.
