Title:
ACCELERATION SENSOR CORRECTION DEVICE, ROAD GRADIENT DETECTOR, AND OPERATION RECORDER
Document Type and Number:
Japanese Patent JP2022174927
Kind Code:
A
Abstract:
To provide an acceleration sensor correction device, a road gradient detector, and an operation recorder that can more accurately correct the gradient detection based on an acceleration.SOLUTION: An acceleration sensor correction device 100 is boarded on a vehicle, comprising: an acceleration sensor 14 for detecting an acceleration applied to the vehicle; a wireless communication unit 3 for receiving information about an atmospheric pressure detected in the vehicle; and a CPU1 which determines whether or not the atmospheric pressure information can be received by the wireless communication unit 3, which determines, when the information can be received, whether or not a road on which an own vehicle is running is flat based on the atmospheric pressure information received by the wireless communication unit 3, and which performs, when it is determined that the road is flat, a zero-point correction of the acceleration sensor 14.SELECTED DRAWING: Figure 1
