Configurable passenger car body control system and parameter configuration method thereof

Abstract

The invention discloses a configurable passenger car body control system which comprises a vehicle-mounted integrated information module and a plurality of configurable control modules, wherein the vehicle-mounted integrated information module comprises a processor, an on-off input port, a control signal output port, high-speed and low-speed CAN bus interface modules, a digital instrument interface, a storage module and an RS232 interface; and each configurable control module comprises a processor module, an on-off and analog input circuit, a control signal output circuit, a low-speed CAN bus communication module and a storage unit. The invention also discloses a parameter configuration method of the system, which comprises the following steps: generating, downloading and interpreting parameter configuration files, wherein input and output signals of the passenger car body control system are set by the parameter configuration files. The invention enables the passenger car body control system to be flexible and universal and to be used on different models so as to meet different customer requirements, has the advantages of short development cycle and low development cost, and facilitates the after-sale service of the cars and the management of standby and spare parts.

Description

technical field [0001] The invention relates to automobile electronic technology, in particular to a CAN bus-based configurable bus body control system and a parameter configuration method thereof. Background technique [0002] The traditional bus body electrical control adopts the cable relay mode. With the increasingly widespread application of electronic technology in passenger cars, the functions and quantity of electronic equipment in vehicles are gradually increasing. The traditional cable relay control method increases the weight of the cable and the complexity of the connection, reduces the reliability of the connection, and reduces the wear and tear of the cable. The aging and aging phenomena have reduced the safety performance of the bus, and it has been difficult to meet the needs of the bus body control. With the advancement of automotive electronic technology, the bus body control technology has gradually developed from the traditional cable relay control metho...

AI Technical Summary

Problems solved by technology

[0005] Due to the increasing number of basic bus models and the customer-to-order production method, different models and customers have different requirements for body control systems, which brings challenges to the development and production of bus body control systems

At present, only the body control systems of different models and different customer needs can be developed and designed separately. One model corresponds to a specific body control system, which is insufficient in flexibility and versatility. The development cycle is long and the cost of research and development is relatively high.

In addition, there are differences in the hardware and software of the bus body control systems of different models and customers, which brings great difficulties to the after-sales service and spare parts management of the OEM
