Automobile intelligent safety device based on CAN bus Chengdu Panfeng Technology

Bus-based automobile intelligent safety device The domestic automobile modification market demand is growing. In response to the demand for more and more automobile modification products, many automobile modification products with practical significance have emerged.
Let's discuss here how to use our company's products to assist in the development of car modification products.
Product function requirements: It can enable low-end cars to automatically lock and light up when emergency braking occurs after speeding up.
First, connect the interface card to the automobile bus network. We use the automobile bus policy development tool to record the bus data according to different vehicle speed conditions during vehicle operation.
Then the recorded data is classified according to the nature of the message to find the vehicle speed message and the relationship between the data content of the message and the vehicle speed is analyzed.
Calculate the acceptance code and masking code for this message based on the hardware platform we are about to use. This will later reduce the overhead of processing unnecessary information in the hardware platform.
The hardware platform structure is as follows:
Software programming realizes the continuous output of the acceleration sensor value from the bus. Use the image test function of the automotive bus simulation development tool to analyze the output value of the acceleration sensor and then determine what value is the best. The value of starting the emergency light then determines a time value that requires the emergency light to be illuminated and another forward acceleration value to end the illumination (the emergency light is automatically released when the vehicle moves forward again).
Since the emergency light and central locking controls are directly integrated into the car's own switches through relay short-circuiting, there is no essential impact on the original control circuit.
