Description

Vehicle spare parts inspection and verification equipment

The invention relates to a detection and verification device, in particular to a network structure of a built-in controller area network or a K-line, simulating a network structure of a physical vehicle, and performing vehicle component detection for setting and testing a vehicle component. Verify the device.

In the prior art, the vehicle diagnostic device is a convenient way for the user to detect the current state of use of the vehicle, such as performance, fault conditions, etc., without disassembling the vehicle body to view its interior. The connection method is through the Diagnostic Socket 114 of the On Board Diagnostics (OBD), which is the International Standard 15031-3 (ISO 15031-3) specification (ie, American Society of Automotive Engineers Standard J1962 (SAE J1962) specifications), and The sixth terminal (pin6; CANHI) and the 14th terminal (pin14; CANLOW) of the diagnostic socket are connected to the controller area network bus. The vehicle diagnostics can be connected to the controller area network (CAN) or K-line (K-LINE) network in the vehicle by simply connecting the diagnostic socket to resolve the vehicle's status and faults.

However, conventional vehicle diagnostic equipment can only diagnose fixed vehicles depending on its hardware. In order to respond to different vehicle models, configuration devices, configuration control components and network architecture, maintenance vendors can only continuously purchase vehicle diagnostic equipment for relative vehicle types, or selectively repair corresponding to the type of vehicle diagnostic equipment purchased. Types of vehicles are quite limited in the scope of maintenance operations and are not easily expandable. Moreover, the vehicle diagnostic equipment is only suitable for vehicles that have been manufactured or have been formed to a certain extent, and the vehicle devices are allowed to operate interactively, and are not suitable for components that are not installed on the vehicle.

On the other hand, because of the use of vehicle diagnostic equipment, it is equipped with hardware. Only the fixed type of vehicle can be diagnosed, so the manufacturer of the vehicle diagnostic equipment can only customize the designed vehicle diagnostic equipment according to the customer's needs, as well as the hardware and network configuration of the vehicle type. Manufacturers need to constantly redesign their circuits and constantly write custom control programs. Moreover, in order to adapt to the revision of the vehicle type, it is necessary to continuously update the control program. In this way, manufacturers must spend considerable manpower, material resources and time.

However, if you want to make the vehicle diagnostic equipment available for a variety of different models, this will be difficult, and the hardware and network configuration of the car will vary. Therefore, how to improve the design and manufacturing efficiency of vehicle diagnostic equipment under the design mode of maintaining a customized vehicle diagnostic device is a problem that manufacturers should consider.

In view of this, the present invention discloses a vehicle component or a K-line network constructed in the vehicle component detection and verification device, which simulates the network structure of the physical vehicle to perform vehicle component assembly and test. Detect the verification device.

The vehicle component detection and verification device disclosed by the invention comprises a plurality of control modules and a central electronic control module. The central electronic control module and the control module are interconnected to form a network structure of a controller area network type or a K line network type.

At least one of the control modules has a control unit, a device connection unit and a memory unit. The device connection unit is configured to connect to a first external device, and the memory unit stores a device parameter table. The control unit is spontaneous or controlled according to the device parameter table to control the operation of the first external device and output the detection of the first external device. At least one of the information.

A central electronic control module is configured to obtain detection data transmitted to the network structure to analyze an operational state of the first external device, and to output a control command to the control unit.

In some embodiments, the central electronic control module stores an operation parameter table of each external device, and obtains an operation state of the corresponding external device from the network structure. According to at least one of the state data and the control data, according to the result of the comparison operation parameter table, it is determined to set an operation parameter table corresponding to the external device, perform an abnormal operation of the device, and provide an abnormal alarm and output to the control unit. At least one of the actions of the control command.

The benefits of the invention are:

(1) The control program of each control module only needs to be written once at the factory. If the control module is damaged during use, or if the external device connected to the control module is replaced, the maintenance personnel or the designer only needs to modify the device parameter table to allow the relevant control module to operate. Connect different external devices or find out if the external device is damaged.

(2) The central electronic control module and each control module communicate with each other through the controller area network or the K line network, so it can be regarded as the vehicle simulation architecture. Therefore, the device parameter table constructed by the designer according to the connected external device must be the most suitable for the actual vehicle. These control modules can be directly integrated to form a corresponding vehicle diagnostics for direct use in the corresponding vehicle type. Therefore, the design process can be simplified to maintain the design convenience effectively while maintaining a customized design mode.

(3) The central electronic control module and each control module communicate with each other through the controller area network or the K-line network, so it can be regarded as the simulation structure of the vehicle, and the central electronic control module is Designed to control the operation of the entire system, including the interaction with external devices connected to it through the control module, so the central electronic control module can be independently designed as a vehicle gateway for vehicles with additional electronic devices (Gateway) ).

(4) Each control module performs data broadcasting and receiving according to the network type of the controller area or the network structure of the K-line network type, and the synchronization and transmission sequence of the data are controlled by the network controller of the network structure. The control module can manage the external devices connected to it and determine whether the data is received/transmitted, which greatly reduces the complexity of the device and program design.
