Abstract
An embodiment system for monitoring a tire pressure includes a wheel speed sensor mounted on each wheel of a vehicle, a set button for resetting a pressure setting, and a controller configured to determine whether the tire pressure is low using the wheel speed sensor, output a low pressure warning, determine whether a user has an intention to reset the pressure setting when a manipulation of the set button is sensed after the low pressure warning is output, and reset the pressure setting in response to a response of the user.
Claims20
A system for monitoring a tire pressure, the system comprising:
- a wheel speed sensor mounted on each wheel of a vehicle;
- a set button for resetting a pressure setting;
- and
- a controller configured to:
- determine whether the tire pressure is low using the wheel speed sensor;
- output a low pressure warning;
- determine whether a user has an intention to reset the pressure setting when a manipulation of the set button is sensed after the low pressure warning is output which includes allowing the user to select by default that the user has no intention to reset the pressure setting;
- and
- reset the pressure setting in response to a response of the user indicating that the user has the intention to reset the pressure setting.
A system for monitoring a tire pressure, the system comprising:
- a wheel speed sensor mounted on each wheel of a vehicle;
- a set button for resetting a pressure setting;
- and
- a controller connected to the wheel speed sensor and the set button, wherein the controller is configured to:
- determine whether the tire pressure is low using the wheel speed sensor;
- output a low pressure warning when the tire pressure is low;
- store tire pressure determination information;
- activate a pressure setting reset prohibition mode when the vehicle is stopped and a manipulation of the set button are sensed;
- and
- output the low pressure warning when a wrong manipulation of the set button is sensed in the pressure setting reset prohibition mode.
A method for sensing malfunction of a system for monitoring a tire pressure, the method comprising:
- inspecting a state of the tire pressure using a wheel speed sensor;
- outputting a low pressure warning when it is determined that the tire pressure is low;
- determining whether a driver has an intention to reset a pressure setting when a manipulation of a set button is sensed during the low pressure warning, wherein determining whether the driver has the intention to reset the pressure setting includes allowing the driver to select by default that the driver has no intention to reset the pressure setting;
- and
- performing a pressure setting reset when the driver has the intention to reset the pressure setting.
A method for sensing malfunction of a system for monitoring a tire pressure, the method comprising:
- performing a first operation of sensing that the tire pressure is low using a wheel speed sensor, outputting a low pressure warning, and storing tire pressure determination information;
- performing a second operation of activating a pressure setting reset prohibition mode and determining whether a manipulation of a set button is a wrong manipulation when vehicle stop and the manipulation of the set button are sensed after the low pressure warning;
- and
- performing a third operation of outputting the low pressure warning when the manipulation of the set button is determined as the wrong manipulation.
