FIELD: measurement equipment.
SUBSTANCE: device (12) for acceleration detection comprises a unit (21) of zero point correction for correction of the position of the zero point of a sensor signal value (Gsen), using the value of correction (absolute value for the correction value (Gd) on the basis of acceleration (Gout), when a vehicle changes from the left condition on the inclined road into the condition of motion, and a unit (20) of correction value limitation to limit the correction value, thus suppressing calculation of excessive value of correction as a result of irregularities of the road surface or movement of a passenger.
EFFECT: invention provides for improved accuracy of correction, limitation of a correction value or setting of a correction limit.
