Abstract
The present disclosure relates to an indirect tire pressure monitoring apparatus. The indirect tire pressure monitoring apparatus includes: a wheel speed sensor for detecting a wheel speed; a reset switch for receiving a reset command for recalibrating the reference value of an indicator used for determining decompression; and a control unit for recalibrating, upon receiving a reset command from the reset switch, the reference value of the indicator according to the wheel speed. The control unit, upon receiving a reset command, compares the reference value of the indicator with a current value to determine whether the tire pressure has been reduced, and prohibits recalibrating the reference value of the indicator if the tire pressure is in a reduced state.
Claims13
An indirect tire pressure monitoring apparatus, comprising:
- a wheel speed sensor configured to detect a wheel speed;
- a reset switch configured to receive a reset command for recalibrating a reference value of an indicator used for determining decompression;
- and
- a control unit configured to recalibrate the reference value of the indicator according to the wheel speed when the reset command is received from the reset switch,
- wherein the control unit is configured to:
- control a display unit to display a state of recalibrating the reference value of the indicator;
- when the reset command is received, compare the reference value of the indicator with a current value to determine whether tire pressure is in a decompression status, and prohibit recalibrating the reference value of the indicator when the tire pressure is in the decompression status;
- and
- when the recalibration of the reference value is prohibited, display a method of releasing the prohibition of recalibrating the reference value on the display unit.
An indirect tire pressure monitoring method of recalibrating a reference value of an indicator used for determining decompression according to a wheel speed, the indirect tire pressure monitoring method comprising:
- when a reset command for recalibrating the reference value of the indicator is received from a reset switch, comparing the reference value of the indicator with a current value;
- determining whether tire pressure is in a decompression status according to the comparison result;
- and
- when the tire pressure is reduced, prohibiting recalibrating the reference value of the indicator,
- wherein the prohibiting of recalibrating the reference value of the indicator includes displaying a method of releasing the prohibition of recalibrating the reference value on a display unit.
