Abstract:
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.
