A signal acquisition apparatus has a vehicle state sensor that outputs measurement results in current form, an overcurrent interrupter connected downstream of the vehicle state sensor, which interrupts an overcurrent due to a short from the output connection of the vehicle state sensor to a battery voltage, and a shunt, connected downstream of the overcurrent interrupter, across which an output voltage corresponding to the output current of the aforementioned overcurrent interrupter is dropped. A control part is provided that controls the operation of the overcurrent interrupter according to the output voltage dropped across the shunt and assesses the measurement results of the vehicle state sensor on the basis of the output voltage.
