Embodiment Construction

[0019] Hereinafter, an embodiment in which the data processing device of the present application is applied to a data processing device for a vehicle that can be mounted on a vehicle will be described with reference to the drawings.

[0020] A vehicle data processing device (DATA PROCESS APPA) 1 can be mounted on a vehicle, and has a digital board 2 (DGTBD) and an interface board 3 (I / F BD). The digital board 2 corresponds to the first board, and the interface board 3 corresponds to the second board. The term "mountable on a vehicle" includes all forms that are mounted on a vehicle in a fixed state and forms that are detachably mounted on a vehicle. The digital board 2 and the interface board 3 are detachably connected via a connection cable 4 . The connector 6 provided at one end side of the cable part 5 of the connecting cable 4 is connected to the connector 7 of the digital board 2, and the connector 8 provided at the other end side of the cable part 5 of the connecting ca...

Abstract

The data processing device includes a digital data processing unit (12) and a control unit (17). The digital data processing unit has a calculation unit (10) for calculating digital data, and a power management unit (11) for transmitting and receiving commands with the calculation unit and managing operating power of the calculation unit. The control unit controls a user interface unit (20, 21) that realizes a user interface function. The control unit monitors the transmission state of the command transmitted between the calculation unit and the power management unit, thereby diagnosing the operation of the digital data processing unit. When the control unit determines that an abnormality has occurred in the operation of the digital data processing unit, it resets a part or the whole of the digital data processing unit without considering the operation of the user interface unit.
