Abstract: A fluid level detecting apparatus detects the level of fluid in a reservoir. When the fluid level detecting apparatus detects that the fluid level has reached a minimum fluid level, an ECU issues a warning. If, after the warning has been issued, the fluid level detecting apparatus detects that the fluid level has reached a failsafe mode operation fluid level, which is lower than the minimum fluid level, the switches a normal control mode to a failsafe mode, and performs brake control using the failsafe mode.

Abstract: A malfunction detection device for a resolver detects malfunction in a resolver with accuracy and stability even if a value of a square sum is varied between inside and outside of a normal range. When the resolver is in malfunction, a sine signal and a cosine signal are read. It is determined whether a malfunction determination of the resolver is prohibited, or not, from read values of the sine signal and the cosine signal, or square values thereof. When it is determined that the malfunction determination of the resolver is prohibited, the count value is accumulated and incremented every time the test value falls outside a normal range. When the count value arrives at a given value or higher, it is determined that the resolver is in malfunction.
