Abstract
A vehicle can include a first acquisition processing unit configured to acquire a related value that is related to an air pressure of each tire; a detection processing unit configured to detect a deflation state of the tire, based on the related value and a predetermined reference value; an update processing unit configured to update the reference value if an operation on an initialization button is accepted; and a first determination processing unit configured to determine whether or not the operation on the initialization button is an incorrect operation, based on a stop status of the vehicle during a period from a time of detection of the deflation state to a time of acceptance of the operation on the initialization button.
Claims18
A deflation state detection system comprising:
- circuitry configured to
- acquire a related value that is related to an air pressure of each pneumatic tire mounted on a vehicle, based on a rotation speed of the pneumatic tire, each time a predetermined acquisition timing arrives;
- detect a deflation state of the pneumatic tire, based on the acquired related value and a predetermined reference value;
- under a condition where a predetermined update operation is accepted, update the reference value, based on the related value acquired during a first period including a time of acceptance of the update operation;
- and
- determine whether or not the update operation is an incorrect operation, based on a stop status of the vehicle during a second period from a time of detection of the deflation state to the time of acceptance of the update operation.
A determination method executed by one or more processors, the determination method comprising:
- acquiring a related value that is related to an air pressure of each pneumatic tire mounted on a vehicle, based on a rotation speed of the pneumatic tire, each time a predetermined acquisition timing arrives;
- detecting, using an electronic detector, a deflation state of the pneumatic tire, based on the related value acquired by said acquiring and a predetermined reference value;
- updating, under a condition where a predetermined update operation is accepted, the reference value, based on the related value acquired during a first period including a time of acceptance of the update operation;
- and
- determining whether or not the update operation is an incorrect operation, based on a stop status of the vehicle during a second period from a time of detection of the deflation state to the time of acceptance of the update operation.
A non-transitory computer-readable storage medium having stored thereon instructions that, when executed by one or more processors, causes the one or more processors to perform a method comprising:
- an acquisition step of acquiring a related value that is related to an air pressure of each pneumatic tire mounted on a vehicle, based on a rotation speed of the pneumatic tire, each time a predetermined acquisition timing arrives;
- a detection step of detecting a deflation state of the pneumatic tire, based on the related value acquired by the acquisition step and a predetermined reference value;
- an update step of, if a predetermined update operation is accepted, updating the reference value, based on the related value acquired during a first period including a time of acceptance of the update operation;
- and
- a determination step of determining whether or not the update operation is an incorrect operation, based on a stop status of the vehicle during a second period from a time of detection of the deflation state to the time of acceptance of the update operation.
