Title:
ACCELERATION CALCULATION DEVICE
Document Type and Number:
Japanese Patent JP2019189175
Kind Code:
A
Abstract:
To provide an acceleration calculation device capable of improving calculation accuracy of acceleration even when a vehicle is inclined to a road surface by baggage or the like, and an axis of an acceleration sensor is inclined to a road surface due to assembly error.SOLUTION: An acceleration calculation device 30 comprises: an output part 40 for outputting an acceleration sensor value according to acceleration of a vehicle in a cross direction detected by an acceleration sensor 24, and travel driving force based on drive force of a drive source of the vehicle and air resistance which acts to the vehicle; and a calculation part 42 for calculating a correction value for correcting the acceleration sensor value on the basis of the plurality of the acceleration sensor values and the plurality of travel drive forces, and on the basis of the correction value, correcting the acceleration sensor value and calculating acceleration.SELECTED DRAWING: Figure 3
