Problems solved by technology

Communication with the control unit of the high-voltage area is not possible, for example, to update the control software (also called firmware update), or communication is interrupted when the high-voltage area is switched off
[0012] Therefore, in an operating state with the high-pressure zone switched off and the low-voltage zone switched on, only the control software for the low-pressure zone can be updated
It is also usually not possible to diagnose high voltage areas and usually not to read stored data from high voltage areas other than updating the control software

Embodiment Construction

[0028] exist figure 1 A schematic diagram of a high-voltage control device 1' known in the prior art is shown in . The high-pressure control device 1' is designed in two parts and has a low-pressure area 2 and a high-pressure area 3. Each zone has its own control device 4 , 5 , for example with a separate microcontroller. The low-voltage area 2 is equipped with a first control device 4, also referred to as LV-MCU, which stands for English "Low-Voltage-Micro-Controller-Unit", and the high-voltage area 3 is equipped with a second control device 5, referred to as HV- MCU stands for "High-Voltage-Micro-Controller-Unit" in English.

[0029] exist figure 1 Within the shown first control device 4, the current version status of the first control software 6 for controlling the first control device 4 is shown, wherein the reference symbol FW represents firmware, and LV-MCU represents that it belongs to the first control device 4 of the control software, and shows the current version...

Abstract

The invention relates to a device and a method for updating control software in a high-voltage control system (1), by means of which it is possible to update the control software independently of the current operating state of a high-voltage region (3) of a high-voltage control system (3) . The device is realized in that the first control device (4) is connected via a first communication line (15) to the communication interface (14) and the means for galvanic separation (19), or the first control device (4) is connected via a first communication line (15) The line (15) is connected to the communication interface (14) and to the means for galvanic separation (19) via a fourth internal communication line (25), and the means for galvanic separation (19) is connected via a third internal communication line ( 20) Connect with the second control device (5).

Description

technical field [0001] The invention relates to a device for updating control software in a high-voltage control device. The high-pressure control device has a low-pressure region with a first control device and a high-pressure region with a second control device. The first control device is connected to the first communication interface via the first internal communication line. In order to update the control software of the high-voltage control device, an external unit is connected to the first communication interface via the first communication line. [0002] The invention also relates to a method for updating the control software in a high-voltage control system, wherein for updating the control software for the first control device new first control software is provided and for updating the control software for the second control device Software provides new second control software. In this case, the new control software is transferred to a storage area of ​​the contro...
