FIG. 3 shows maintenance data as an embodiment of the off-board diagnostic device of FIG. 1. The maintenance number is displayed as a data table, wherein the data table is comprised of header data and data records. The header data includes maintenance event, advance criteria, maintenance criteria, shop ID. A maintenance event is an event in which the wear member must be serviced. The wear element may be a tire, a fire extinguisher, a coolant, a tire sealant, a brake fluid, and/or an emergency kit. In these cases, the maintenance event is a tire maintenance, a fire extinguisher maintenance, a coolant maintenance, a tire sealant maintenance, a brake fluid maintenance, and/or an emergency kit maintenance. The service criteria include a date of manufacture, a service interval, and/or a date of failure of the wear member. An advance criteria is determined based on the maintenance criteria. The advance criterion may be predefined or input by a user. The maintenance standards of the tire are the production date (10 and 15 days in 2013) and the tire life (6 years). The lead standard of the tire was determined by adding the tire life (6 years) to the production date (2013, 10, 15 days) and subtracting 2 months. The maintenance standards of the fire extinguisher are the last maintenance date (5 months and 21 days in 2019) and the maintenance interval (2 years). The lead standard for fire extinguishers was determined by adding the last maintenance date (5/21/2019) to the maintenance interval (2 years) and subtracting 2 months. The maintenance standard for the coolant is the expiration date (7 months and 11 days in 2017). The advanced standard for coolant was determined by subtracting 2 months from the expiration date (7 months and 11 days 2017). The maintenance criteria for a tire sealant is the expiration date (8 months and 2 days 2018). The advanced standards for tire sealants were determined by subtracting 2 months from the expiration date (8 months and 2 days 2018). The maintenance standard for brake fluid is the expiration date (5 months and 21 days in 2019). The advanced standard of brake fluid was determined by subtracting 2 months from the expiration date (5 months and 21 days 2019). The maintenance standard for the first aid kit is the expiration date (7 months and 21 days 2019). The advance standard for the first aid kit is determined by subtracting two months from the expiration date (07/21/2029). Tire maintenance, fire extinguisher maintenance, and brake fluid maintenance are stored in association with the plant-1, and coolant maintenance, tire sealant maintenance, and first kit maintenance are stored in association with the plant ID. Each maintenance event is therefore connected to the workshop via the workshop ID and the off-board diagnostic device 100 can identify which workshop is responsible for the determined maintenance event.
In this embodiment, the advance criterion is based on a time criterion. However, the embodiments are not limited to time standards, and other standards may be used. The advance criteria may be determined, for example, using distance criteria, temperature criteria, and/or the like. Furthermore, pressure standards, for example tire pressure, which can be transmitted via valves, sensors or antennas, can be used.
Fig. 4 shows a flow chart as an example for preventive maintenance. In step 400, a maintenance standard is entered. In step 400, a maintenance standard is input via the input unit (200 in fig. 1). If the tire is replaced in maintenance, the maintenance person can input the manufacturing date and the tire life of the tire using the input unit (110 in fig. 1). The input information may also be input through the plant data processing system (230 of FIG. 2). In step 410, an advance criteria is determined based on the entered service criteria. The advance criteria may be predefined or set by the user. For example, when the advance criterion is predefined, if the maintenance criterion is a time criterion, the advance criterion is determined by subtracting two months from the maintenance criterion. Actual criteria are obtained in step 420. The actual criteria may be derived from an internal clock of a server (210 of fig. 2), a vehicle data processing system (220 of fig. 2), a shop floor data processing system (230 of fig. 2), or an off-board diagnostic device (100 of fig. 1). In step 430, the advance criterion value is obtained by subtracting the actual criterion from the advance criterion. In step 440, the advance criterion value is compared to a preset threshold value. If the advanced criteria value is greater than the preset threshold, the process returns to step 430. If the advanced criteria value is equal to the preset threshold, the process continues with step 450. A pre-service signal is generated in step 450. The pre-service signal may be an alarm in the form of text and displayed on the display unit (120 of fig. 1). Further, the pre-service signal may be transmitted to a server (210 in FIG. 2), a vehicle data processing system (220 in FIG. 2), and/or a shop data processing system (230 in FIG. 2). In step 460 it is determined whether the advance criteria are updated. The update may be based on maintenance data provided by the server (210 of FIG. 2), the plant data processing system (230 of FIG. 2), or information entered by the user through the input unit (200 of FIG. 1). If the advance criteria are updated, the process continues with step 400, and if the advance criteria are not updated, the process continues with step 480. The user is contacted in step 480. The user information may be stored in the storage unit (150 of fig. 1) or acquired by the server (200 of fig. 2). The desired contact information of the user can be obtained from the user information previously stored in the storage unit (150 of fig. 1). The contact information may alternatively be obtained from a server (200 of fig. 2).
