Body control module assembly introduce

1. The body control module assembly transmits commands: the speed control command triggers a signal, which comes from the vehicle controller. On the one hand, the body controller reflects the driver's intention, and on the other hand, from the perspective of safety and the operation status of the vehicle electrical system, evaluates whether the response to the driver is reasonable, Finally, execute or discount the execution. The driver's intention is expressed and transmitted to the vehicle controller through the accelerator and brake pedals. 2. Adjust the operating status of the equipment: The specific instructions given by the vehicle controller to the motor controller are related to the power system, including acceleration, deceleration, braking, parking. The response made by the motor controller is to change the power supply current, voltage, frequency and other parameters, Ensure that the operating status of the motor meets the needs of the controller. 3. Detection feedback: If different motors have different thermal characteristics, different start stop control schemes should be adopted when continuously driving the motor to avoid motor overheating. The vehicle controller should consider using mature technology and products, and minimize the occurrence of faults in design selection and system design. Choosing intelligent chips can monitor the status of electrical equipment and provide feedback to microcontrollers)

Introduction to Body Control Module

The function of the body control module is to achieve discrete control functions and control numerous electrical appliances, mainly controlling the electrical appliances of the car body, such as lamps, wipers, door locks, electric windows, skylights, etc. It is the switch signals of these appliances that are input to the BCM, which directly or through relays controls the corresponding electrical appliances to work. With the development of automobiles, the comfort of automobiles is also constantly improving, which makes the application of automobiles more and more, More powerful modules are needed to control it. The editor will introduce the body control module. Introduction to body control module: The functions of the body control module include: electric door and window control, central door lock control, remote anti-theft, lighting system control, electric rearview mirror heating control, instrument backlight adjustment, power distribution, etc

Mercedes Benz B-Class introduce

This Mercedes Benz B-Class is currently the cheapest entry-level car with the Mercedes Benz logo, and it is also the cheapest model in China that is equipped with an active parking assist system. In addition, there is a unique panoramic sunroof structure. Unlike the Mercedes Benz C200, the Mercedes Benz B200 uses a specially designed 2.0L inline four cylinder engine installed in the car with a slight tilt, which not only complements the special chassis structure of the B200, but also, And it can keep the cockpit as far away from the frontal collision area as possible. It is equipped with an AUTO TRONIC continuously variable transmission, also known as a CVT transmission. After being recalibrated by Mercedes Benz, it can output a maximum power of 100 kW and a torque of 185 Nm. In actual testing, the initial response of the electronic throttle is still a bit sluggish, but it is most frequently used in the area of 2500 to 3500 rpm, Having sufficient low torque performance for daily use. After shifting the gear to manual mode, the CVT gearbox with a 7-speed setting immediately enters sport mode, and the switching method is also more convenient. Although it enters sport mode, it is obvious that this car is not born for sport, so the expected value should not be too high, and the sport mode cannot have the expected push back feeling As a compact sports wagon, the Mercedes Benz B-Class has a stylish and dynamic appearance. The large three pointed star emblem on the front face is embedded in the center of the trapezoidal grille, revealing its identity. The lines on the engine compartment cover contract inward, making the headlights on both sides more sharp. The combination of the bumper and front fog lights gives the Mercedes Benz B-Class a powerful appearance
