Control device

The invention provides a control device which appropriately diagnoses the state of equipment installed in a vehicle. A control device (60) for a vehicle (1) in which an engine (11), a first motor generator (21) (generator) capable of generating electricity by power output from the engine (11), and a second motor generator (23) (drive motor) connected to drive wheels (33) are connected via a planetary gear mechanism (31), the control device (60) being provided with a control unit. And a control unit that diagnoses the state of at least one of the engine (11), the first motor generator (21), and the second motor generator (23) on the basis of the relationship between the number of revolutions of the engine (11), the first motor generator (21), and the second motor generator (23). 本发明提供一种控制装置，其适当地诊断搭载于车辆的设备的状态。控制装置(60)是经由行星齿轮机构(31)而连接有发动机(11)、能够利用从发动机(11)输出的动力而发电的第一电动发电机(21)(发电机)、以及与驱动轮(33)连结的第二电动发电机(23)(驱动用马达)的车辆(1)的控制装置(60)，所述控制装置具备控制部，该控制部基于发动机(11)、第一电动发电机(21)以及第二电动发电机(23)的转数的关系来诊断发动机(11)、第一电动发电机(21)以及第二电动发电机
