Description

Technical Field

[0001] The utility model relates to a flashing device for an automatic transmission, in particular to a portable flashing tool for a transmission with a power supply. Background Art

[0002] During the offline matching process of the automatic transmission, technicians are required to flash the software, calibrate the data and update the program of the automatic transmission; during the subsequent maintenance service stage of the automatic transmission, staff are required to perform fault diagnosis, data collection, software flashing and other tasks on the automatic transmission. The existing way to connect the automatic transmission is to connect the automatic transmission through the vehicle OBDⅡ (On-Board Diagnostics) interface to perform software flashing, fault diagnosis and other tasks; or to remove the TCU (Transmission Control Unit) from the automatic transmission and connect it through the TCU flashing harness to complete the corresponding work.

[0003] However, after the automatic transmission is offline, it cannot be matched with the whole vehicle immediately. If the automatic transmission program is to be flashed, the TCU needs to be removed, which affects work efficiency. At the same time, after matching the whole vehicle, the diagnosis and flashing of the automatic transmission may be affected due to the complex signal status of the whole vehicle or the error nodes of the whole vehicle. Whether the automatic transmission is connected to the whole vehicle or the TCU flashing program is connected separately, the whole vehicle or an additional power supply is required for power supply, and technical support cannot be provided conveniently and quickly. In addition, because the network environment of the vehicle CAN (Controller Area Network) is complex, if the whole vehicle sends an error signal or there is a problem with the power supply of the whole vehicle, it will affect the data flashing of the transmission, greatly reducing the work efficiency of the TCU staff.

[0004] The traditional automatic transmission flashing harness is either connected to the vehicle's OBDⅡ interface, or uses the male head of the vehicle-automatic transmission wiring harness converter to draw out the vehicle's power supply. Both require the participation of the entire vehicle to perform automatic transmission data flashing and other tasks, making it difficult for TCU calibrators to directly flash the automatic transmission data.

[0040] like Figure 1 As shown, a portable transmission flashing tool with power supply includes a first docking plug 1, a second docking plug 2, a control switch 4, a battery assembly and a power plug 6;

[0041] The battery assembly includes a battery 5, a 30-volt battery and a 15-volt battery. The battery 5 is connected to the 30-volt battery and the 15-volt battery through a control switch 4.
