1. A failure detection device for a vehicle that detects a failure of a motor system, comprising:
- a controller that changes a sensitivity for detection of a failure in the motor system, to one of a plurality of predetermined sensitivity levels, in accordance with (1) an operational condition of the motor system and (2) a situation in which the motor system is operating,wherein the controller determines the operational condition of the motor system and determines the situation in which the motor system is operating,the controller sends a command to at least one of a plurality of subsystems of the vehicle that are under control of the controller, depending on the determined operational condition of the motor system and the situation in which the motor is operating,upon reception of the command from the controller, the at least one of the plurality of subsystems of the vehicle changes the sensitivity for detection of a failure in the motor system,wherein the controller sets the sensitivity for detection of a failure to a lower level, from among the plurality of predetermined sensitivity levels, when a shift range is set to a parking range, than when the shift range is set to an other range.

7. A failure detection device for a vehicle that detects a failure of a motor system, comprising:
-
a controller configured to; determine an operational condition of the motor system and a situation in which the motor system is operating; set a sensitivity level for detection of a failure in the motor system, to one of a plurality of predetermined sensitivity levels, in accordance with the determined operational condition of the motor system and the determined situation in which the motor system is operating; send a command, which includes the sensitivity level, to at least one of a plurality of subsystems of the vehicle that are under control of the controller, depending on the determined operational condition of the motor system and the situation in which the motor is operating; wherein the at least one the plurality of subsystems of the vehicle changes the sensitivity, for detection of a failure in the motor system upon reception of the command from the controller wherein the sensitivity level for detection of a failure in the motor system is a lower level, among the plurality of predetermined sensitivity levels, when a shift range is set to a parking range, than when the shift range is set to an other range. - View Dependent Claims (8, 9)

10. A failure detection device for a vehicle configured to detect a failure of a motor system, wherein the vehicle includes a power-generating motor system and a driving motor system, the failure detection device comprising:
-
a controller configured to; determine an operational condition of the motor system and a situation in which the motor system is operating; set a sensitivity level for detection of a failure in the motor system, to one of a plurality of predetermined sensitivity levels, in accordance with the determined operational condition of the motor system and the determined situation in which the motor system is operating; send a command, which includes the sensitivity level, to at least one of a plurality of subsystems of the vehicle that are under control of the controller, depending on the determined operational condition of the motor system and the situation in which the motor is operating; wherein the at least one of the plurality of subsystems of the vehicle changes the sensitivity for detection of a failure in the motor system upon reception of the command from the controller, wherein when a shift range moves from a non-parking range to a parking range, the controller sets the sensitivity level for detection of a failure in the motor system to a first mode, wherein when the shift range moves from the parking range to the non-parking range, the controller sets the sensitivity level for detection of a failure in the motor system to a second mode or a third mode, wherein the first mode has a lower sensitivity level than the second mode and the third mode.
