IPC: G01W1/14
Filed: 2011-07-19
Abstract: PROBLEM TO BE SOLVED: To provide a raindrop detecting apparatus using a light emitting device and a light receiving device to detect raindrops with a high accuracy by effectively reducing external light components, and to be configured at low cost.SOLUTION: In a state detecting apparatus, a light reception signal from a photodiode PD11 is inputted via a current high-pass filter circuit 20, a current-voltage converting circuit 30, a voltage high-pass filter circuit 40, a peak hold circuit 50 and a non-inversion amplifying circuit 60 to a control unit 70 that generates raindrop information. As an offsetting unit 41 in the voltage high-pass filter circuit so offsets the light reception signal as to keep any undershoot arising from the filtering at or above a minimum input voltage that can be inputted to the peak hold circuit, no expensive analog switch preventing input of any undershoot is required. As the non-inversion amplifying circuit also performs a function of an output buffer, no output buffer is needed either. The current high-pass filter circuit enables a conversion efficiency of the current-voltage converting circuit and accuracy of the detection high.

Filed: 2011-07-28
Abstract: PROBLEM TO BE SOLVED: To solve a problem which is difficult to identify an error point when a short circuit failure occurs in switching elements Swp and Swn of an inverter IV.SOLUTION: When a short circuit failure occurs, the inverter IV and a high-voltage battery 20 are separated by turning off relays SMR1 and SMR2.

When the current detected by the current sensors 26 and 28 exceeds the detectable range of these sensors, each one of the switching elements Swp and Swn which constitute the inverter IV is turned on. Based on the fact that the current changes at that time, it is identified that a short circuit failure occurs in the switching element which is series-connected to the switching element which is turned on.
