Title:
VEHICLE STOPPAGE DETERMINATION DEVICE
Document Type and Number:
Japanese Patent JP2022059964
Kind Code:
A
Abstract:
To provide a vehicle stoppage determination device that performs a highly accurate vehicle stoppage determination.SOLUTION: A vehicle stoppage determination device comprises: an angular velocity sensor; a wheel speed sensor; a calculation unit that calculates a disparity value; a determination unit that determines whether a vehicle is in a parking state or in a moving state; and an execution unit that executes learning at a time of parking of the angular velocity sensor provided the determination unit determines that the vehicle is in the parking state, and does not execute the learning at the time thereof during a period in which the determination unit determines that the vehicle is in the moving state. The determination unit is configured to, when the wheel speed which the wheel speed sensor detects is zero and a divergence value is less than a reference divergence value, determine that the vehicle is in the parking state, and when the wheel speed which the wheel speed sensor detects is not zero, or the divergence value is equal to or greater than the reference divergence value, determine that the vehicle is in the moving state. Accordingly, the vehicle stoppage determination device can be obtained that performs a highly accurate vehicle stoppage determination.SELECTED DRAWING: Figure 2
