The functional application control of the intelligent chassis system has become a new field which is hot and is in the whole automobile industry at present. The intelligent chassis field requires an expandable chassis dynamic control function module, which not only has the existing application of traditional general purpose input/output (General Purpose Input Output, GPIO), a controller area network bus (Controller Area Network, CAN), a controller area network bus (CAN with Flexible Data-rate, CAN FD) with flexible data rate and the like, but also needs to highly integrate sensors and actuator signals such as a fuel door position sensor, a fuel door request switch, a caliper motor drive, a fuel door control lock motor drive and the like, and CAN expand the three-way inertial navigation related to active/semi-active vibration absorption, a large number of automobile-level sensors and signal processing such as a front wheel vertical sensor and the like, and is realized and applied by a series of data fusion and algorithm control and development functions such as braking/steering and the like matched with intelligent driving functions of different levels.

Detailed Description

In order to provide a cost-effective implementation of the test device, embodiments of the present utility model provide a test device, and a preferred embodiment of the present utility model is described below with reference to the accompanying drawings.

In the process of designing, developing and testing a controller module of a current intelligent chassis system, a designer generally adopts two modes aiming at the development and the test of different controller modules.

The first way is to lead out the power supply, input and output signals on the controller module by using a flying lead welding mode by developing testers so as to connect various sensors, actuators and other devices or connect various test devices such as a universal meter, an oscilloscope and the like. This approach tends to have many unorganized, exposed temporary flying leads that are used to transmit various signals, including, for example, power signals, ground signals, various sensor and actuator signals. If the harnesses are not subjected to special treatments such as insulation and isolation, the module has risks such as power short circuit, electrostatic damage to devices, electric shock to development and test personnel, and the like, the difficulty of module debugging is increased, project research and development cost is increased due to the multiple of damage of the module, and meanwhile, the research and development period of the project is passively prolonged.

The second way is to develop a special test device for the design of the controller module with different functions by a development tester, and the controller module and the test device are connected through a standardized wire harness. Signals of various sensors, actuators and the like which are required to be connected by the controller module are connected with the corresponding sensors and actuators through standard wiring harnesses of the testing device. This approach fundamentally avoids the problems that the first approach may encounter in developing tests. This approach is currently the technology employed by most automobile manufacturers in the development and testing of controller modules.

Through analysis of related technologies, most of the existing testing devices only can meet the requirements of development of a traditional controller module and functional application of a testing box, and cannot meet the characteristics of multiple sensors, complex signals, multiple power supplies, complex execution devices, individuation definition and the like in the existing intelligent chassis system. Meanwhile, the existing testing device can only meet the design and development requirements of a single chassis domain controller module, and cannot adapt to various control modules. For the controller modules in different projects, different testing devices often need to be developed and designed to meet the development and test requirements of different controller modules. Such different test devices often have no value to use after the development test is completed before a particular project. This approach can enable automobile manufacturers to accumulate many discarded test devices, a wasteful and environmentally unfriendly behavior. This approach also increases the cost of development for the manufacturer from a cost control perspective.

To this end, an embodiment of the present utility model provides a test apparatus, including a housing and a test module mounted inside the housing: the shell comprises a front panel and an upper cover plate, wherein a power input wire harness interface and a wire harness interface connected with the expandable intelligent chassis dynamic control module are arranged on the front panel, and the power input wire harness interface is used for externally connecting a power supply and providing large-current power input for the controller module to be tested; the wire harness interface connected with the expandable intelligent chassis dynamic control module is used for connecting with the controller module to be tested so as to acquire input and output signals of the controller module to be tested; the testing module is used for receiving input and output signals of the controller module to be tested, the testing module is divided into a plurality of functional testing areas, and each functional testing area of the testing module is connected with a corresponding functional testing area on the upper cover plate; the upper cover plate is a test panel, the test panel comprises a plurality of functional test areas, each functional test area of the test panel is connected with a corresponding functional test area on the test module and is used for receiving input and output signals of the corresponding functional test area on the test module, so that corresponding functional tests are carried out on the controller module to be tested. The testing device integrates various functional tests, can meet the testing work of debugging, monitoring, collecting and the like of data signals of various controller modules in driving control units related to extensible domains of various intelligent chassis at present, quickens the development progress, improves the development testing efficiency, shortens the development period, and saves the cost for project development on the premise of ensuring the quality of final signal data.

The utility model designs a multifunctional testing device for application development of an expandable chassis dynamic control module, which can meet the real-time testing purpose of the expandable chassis dynamic control module in an intelligent chassis system aiming at multiple paths of complex data signals in function application development. The testing device can effectively solve the inconvenience and the problem encountered by the dynamic control module of the extensible intelligent chassis in the early design development test, and is convenient for hardware and software designers to measure the input and output signals of the controller module in various dimensions in the development test process before mass production of the module. The test device can also be used as auxiliary equipment for durability test, reliability test and electromagnetic compatibility test of the module. In addition, the testing device is clear in structure and convenient to operate.

Taking fig. 1 as an example, if the size of the housing 100 in fig. 1 is 245mm×165mm×65mm, the surface of 245mm×165mm (length×width) may be the surface shown as 102 in fig. 1, and the surface may be used as the upper cover. The shortest side of the surface is 165mm (i.e., wide), so that a surface perpendicular to the upper cover plate 102 and having a common side (165 mm wide) with the upper cover plate 102 can be used as the front panel 101, see 101 in fig. 1.

In one possible implementation, the entire test device, and in particular the housing 100, is made of an insulating acrylonitrile-styrene-butadiene copolymer (Acrylonitrile Butadiene Styrene, ABS) material that ensures both the strength and durability of the device, and also the personal safety of the actual operation of the development tester, thus achieving both the goals of compactness, portability, and robustness of the test device.
