FAQs Regarding Our Body Control Module Reference Design, Architecture and Services
Ans. Our Reference design of the Body Control Module (BCM) supports following features/functionalities:
- Mirror Control
- Window control
- Seat Control
- Lamp Load
- Solenoid Control
- 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 vehicle diagnostics protocol in the new age automobiles; viz; SAE J1939, OBD2 (ISO 15031) and UDS (ISO 14229)
J1939 can be integrated for commercial vehicle applications while UDS/OBD can be integrated with passenger vehicles.
Ans. We only provide the reference design for the Body Control Module only. The solution can be customized based on the requirements.
Ans. Following are some of the application level features or the algorithms which are the part of of our body control module reference design:
- Trip Fuel Economy
- Fuel Consumption
- Fuel Meter
- Gear Shift Assistance
- Vehicle speed
- Engine Speed
Ans. There are 3 CAN ports supported by the BCM.
- PCAN- For Power Train
- DCAN- For Diagnostics
- One more CAN sub-network for Cluster and Telematics
Ans. Yes, our BCM reference design is compatible with commercial as well as passenger vehicle.
Ans. Yes, the BCM supports LIN Subnet. If there are certain specific requirements that need LIN to control exterior components like wiper, the same can be integrated in the body control module.
Ans. Our Body Control Module design supports a 5-layered architecture.
A model based development approach has been followed to develop this.
The base software (BSW) is integrated with application software (can be AUTOSAR compliant , non-AUTOSAR compliant or Model Based Development) depending on the customers’ requirements.
Ans. The BCM reference design has been developed on a MPC5674F Microcontroller from Freescale platform. However, we have expertise in working on a range of microcontroller like Renesas, Fujitsu, Texas, Atmel, Cypress and others.
Ans. Yes, the body control module reference design has been developed strictly under functional safety guidelines.
Ans. We are supporting XCP and CCP based calibration. These stacks are readily available and can be configured based on the customers’ requirements. In addition, UDS based diagnostic calibration is also supported.
Ans. Our codes strictly adhere to the MISRA C 2012 guidelines.
Ans. We offer the following documentation and testing services for our BCM software:
- Low Level and High Level Design Documentation
- API Documentation for software components
- Module Level Test Plan and Report: Unit testing, functional testing, and integration testing are performed during the product development lifecycle. These tests are carried out on the basis of test case plan and a report is generated post the tests.
- Functional Test Plan & User Acceptance Testing: For the application software, we perform the functional testing and user acceptance testing, for a bug-free code.
- Manual testing: Manual testing is performed for the low level drivers.
- Unit Testing,Static Analysis and Script Testing: The static analysis is performed using the Check C tool. For unit testing tools like Tessy and Check C are used. Script testing helps in ensuring a Modified condition/Decision coverage.
- Integration Testing: If the BCM application has some additional software component specified by the customer, an integration testing of the software modules is performed.
- Branch Coverage: Branch coverage ensures that each branch of the code is tested for true as well as false cases. This is to prevent any abnormal behavior of the application at any stage.
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:
- A Microcontroller, best suited for the use-case/automotive application
- Communication Interfaces (CAN, LIN, MOST etc.)
- Load Drivers
- 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.
