Problems solved by technology

[0004] (1) Cannot provide real and effective bus control node input and output data and its data throughput rhythm, resulting in a large gap between the data running on the bus and the actual situation, resulting in a lack of testing and evaluation of the comprehensive performance of the vehicle CAN-BUS Practical meaning
[0005] (2) It cannot reflect the impact of changes in the bus control node control strategy and algorithm on the vehicle CAN-BUS data operation status, so it is difficult to adapt to the inevitable repeated debugging, adjustment and optimization design work requirements in product development
[0006] (3) An on-board CAN-BUS comprehensive performance evaluation index system for the integrated control of the chassis electronic control unit cannot be provided, resulting in a disconnect between testing and evaluation, and the inability to form integrated processing capabilities, which has become a bottleneck restricting the improvement of product development work efficiency

Abstract

The invention discloses an automobile chassis integrated control-oriented vehicle-mounted CAN-BUS testing and evaluation system, which comprises a CAN interface 7, a system bus and management unit 8, an LAN interface 9, a bus control node 10, an LAN 11 and an entire automobile simulator 12. The entire automobile-mounted CAN-BUS to be tested, consisting of a chassis CAN-BUS 1, an automobile body CAN-BUS 2, an automobile body gateway 3, a CAN instrument 4, an engine gateway 5 and an engine CAN-BUS 6, is connected with the bus control node 10 through the CAN interface 7; and the bus control node 10, the system bus and management unit 8 and the entire automobile simulator 12 are connected to the LAN 11 by the LAN interface 9. The invention provides an efficient and convenient vehicle-mounted CAN-BUS combination property testing and evaluation device for the product design and development of an integrated control type electric control automobile chassis.

Description

technical field [0001] The invention relates to the manufacturing field of a test and evaluation device used for a vehicle-mounted electronic system, especially a vehicle-mounted CAN-BUS. Background technique [0002] As one of the key systems of the integrated control electronically controlled vehicle chassis, the structure, performance and organizational form of the vehicle CAN-BUS and its node electronic control unit have a decisive impact on the performance of the chassis and the entire vehicle. For this reason, in the product development process of integrated control electronically controlled vehicle chassis, it is necessary to establish a corresponding test and evaluation system to provide efficient and convenient vehicle-mounted CAN-BUS is a comprehensive performance test and evaluation method, and it is an integral part of the product development process. [0003] There are various CAN-BUS test tools, from the lowest-end RS232CAN analyzer to a series of CAN simulati...
