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)
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
The Roewe RX5, an internet SUV launched by SAIC Roewe in 2016, adopts "Blue Core" high-efficiency power technology and is equipped with two 2.0T and 1.5T inline direct injection turbocharged engines. Specifically, the 2.0T engine has a maximum power of 220 horsepower, a peak torque of 350 Nm, and a minimum combined fuel consumption of 8.1L per 100 kilometers; The 1.5T engine has a maximum power of 169 horsepower, peak torque of 250 Newton meters, and a comprehensive fuel consumption of only 6.8L per 100 kilometers. In addition, the Roewe RX5 adopts Porsche chassis tuning, GKN intelligent real-time four-wheel drive system, fully independent suspension system, and all four high-speed CANBUS system bus, which are homologous to Land Rover, to comprehensively improve driving and riding quality
