Vehicle for recognizing road sign using at least one sensor and method thereof

A method of controlling a vehicle, the method comprising:

• receiving information related to a plurality of signs of different types installed on a road;
• determining whether each of the plurality of signs is related to an external temperature of the vehicle or an external wind speed of the vehicle;
• calculating distance information between the plurality of the signs when all of the signs are related to the external wind speed of the vehicle;
• recognizing at least one sign, from among the plurality of signs, installed on the road using a front camera;
• determining a type of the at least one sign;
• in a case in which the at least one sign corresponds to a falling stone warning sign based on referring to a memory, determining whether a speed sensed by a wind speed sensor installed outside the vehicle is a falling stone danger wind speed;
• in a case in which the speed sensed by the wind speed sensor corresponds to the falling stone danger wind speed, determining whether a sunroof of the vehicle is in an open state
• in a case in which the sunroof of the vehicle is in the open state, displaying a sunroof automatic closing notification message through an instrument panel;
• and
• transmitting a command for closing the sunroof to a sunroof controller.

• recognizing at least one sign, from among the plurality of signs, installed on the road using a front camera;
• determining a type of the at least one sign;
• in a case in which the at least one sign corresponds to a crosswind warning sign based on referring to a memory, determining whether a speed sensed by a wind speed sensor installed outside the vehicle is a dangerous wind speed;
• in a case in which the speed sensed by the wind speed sensor corresponds to the dangerous wind speed, determining whether a current speed of the vehicle is a dangerous vehicle speed;
• in a case in which the current speed of the vehicle is the dangerous vehicle speed, displaying a deceleration notification message due to a crosswind through an instrument panel;
• and
• transmitting a command for decelerating the current speed of the vehicle to a drive mode controller.

A vehicle comprising:

• a camera configured to recognize at least one sign installed on a road;
• and
• a controller configured to determine a type of the at least one sign, in a case in which the at least one sign corresponds to a road freezing sign based on referring to a memory, determine whether a temperature sensed by a temperature sensor installed outside the vehicle is a freezing danger temperature, and in a case in which the temperature sensed by the temperature sensor corresponds to the freezing danger temperature, determine whether a drive mode of the vehicle is set to a winter mode,
• wherein the controller is further configured to display a winter mode automatic switching notification message through an instrument panel and to transmit a command for switching to the winter mode to a drive mode controller in a case in which the drive mode of the vehicle is not set to the winter mode.

A vehicle comprising:

• a camera configured to recognize at least one sign installed on a road;
• and
• a controller configured to determine a type of the at least one sign, in a case in which the at least one sign corresponds to a road freezing sign based on referring to a memory, determine whether a temperature sensed by a temperature sensor installed outside the vehicle is a freezing danger temperature, and in a case in which the temperature sensed by the temperature sensor corresponds to the freezing danger temperature, determine whether a drive mode of the vehicle is set to a winter mode,
• wherein the controller is further configured to, in a case in which the at least one sign corresponds to a falling stone warning sign based on referring to a memory, determine whether a speed sensed by a wind speed sensor installed outside the vehicle is a falling stone danger wind speed, and in a case in which the speed sensed by the wind speed sensor corresponds to the falling stone danger wind speed, determine whether a sunroof of the vehicle is in an open state, and
• wherein the controller is configured to control a sunroof automatic closing notification message to be displayed through an instrument panel and to control a command for closing the sunroof to be transmitted to a sunroof controller in a case in which the sunroof of the vehicle is in the open state.
