Through the actual research, this paper summarizes the characteristics of the automotive wiring harness manufacturing process documentation, analyzes the functions of the system, and designs the overall structure and function modules of the wiring harness design system. System for the information provided help, and achieved good results. Practice has proved that the automotive wiring harness manufacturing process design and production has a positive effect.
Product Database: Some graphical information and basic material information are recorded in the process of wiring harness. For example, during the design of the connector, the following fields must appear in the database to meet various functional requirements of the system: Connector ID , Plug-in graphic handle, plug-in function marked handle, drawing number handle, the main harness, surface coating, coating pieces.
The regenerative braking system is unique to electric vehicles and converts part of the functions of the vehicle into electrical energy during deceleration braking. The converted electrical energy is stored in the storage device, eventually increasing the driving range of the vehicle. If the accumulator has been fully charged , Regenerative braking will not be able to achieve the required braking force can only cloth conventional hydraulic system to provide. Now almost all cars are equipped with a regenerative braking system for energy recovery.
Since the bus data in the LIN protocol contains the synchronization signal, the slave node can also perform reliable communication without a very stable local oscillator. Through the software can dynamically adjust the local receive baud rate, so as to achieve the receiving baud rate self-synchronization. At the same time, LPC921 chip integrates hardware functions, and has its own independent oscillator, can be used to do the main oscillator failure detection, in the program, we added the main function of the watchdog register clear instructions. So once the slave is working abnormally, the system will be reset to ensure the reliable operation of the system.
