Bus-type automobile body control system and method

Abstract

The invention discloses a bus-type automobile body control system and a method; the system comprises a combined instrument module, a main controller module, a rocker switch module, a plurality of input-output modules, a slave controller; the above modules are respectively provided with two CAN bus interfaces CAN1 and two CAN bus interfaces CAN2, and two address wakening wire interfaces, address wakening wires are connected with the modules by the address wakening wire interfaces of the modules to form a closed loop; the CAN bus interfaces CAN1 and CAN bus interfaces CAN2 are respectively connected to form two redundancy CAN bus network. The system has system data automatic backup and restoring functions, and can restore the original properties by self under the condition that the single part of the system is replaced, the maintenance quantity is low and the reliability is high, the system design flexibility is solved and the system maintaining cost is not improved at the same time.

Description

technical field [0001] The invention relates to a bus type vehicle body control system and method, which are mainly used in the field of commercial vehicle body control. Background technique [0002] In the field of commercial vehicles, due to the characteristics of small batches, many types, and different body configurations in the production of commercial vehicles, the control system is required to have certain flexibility in design to meet the different needs of customers. In order to meet the needs of customers for flexibility, there are two solutions in the industry: Option 1. Keep the hardware unchanged and change the software; Option 2. Upgrade the software and hardware at the same time to form new products. For the former, one piece of hardware corresponds to multiple software versions, which is difficult to maintain. After a problem occurs, the original factory technicians are generally required to solve the problem on site. However, due to the inherent characterist...

Problems solved by technology

For the former, one piece of hardware corresponds to multiple software versions, which is difficult to maintain. After a problem occurs, the original factory technicians are generally required to solve the problem on site. However, due to the inherent characteristics of vehicles such as dispersion, mobility, and repeated power-on It often causes problems such as long maintenance time and huge maintenance costs, which affect customer satisfaction; for the latter, the software and hardware versions are few and consistent. After a problem occurs in the system, the damaged parts can be replaced. There is no need to update the software, and the maintenance difficulty is small, but the flexibility Insufficient, it is difficult to meet customer requirements during design, and there are many spare parts for maintenance, and the maintenance cost is relatively high

All in all, the above two solutions have not found a best fit in terms of how to improve the flexibility of system design and effectively reduce the difficulty and cost of system maintenance
