Apparatus and method for controlling driving of vehicle

A method of controlling driving of a vehicle, the method comprising:

• obtaining, by a sensor, external environment information of the vehicle, wherein the obtained external environment information includes weather information and road surface information of a road on which the vehicle is traveling;
• setting, by a controller, as a minimum sensing distance, a distance to an obstacle located at a maximum distance detectable by the sensor with a probability that is equal to or greater than a specified probability;
• calculating, by the controller, a target driving speed based on at least one of the weather information, the road surface information, or the minimum sensing distance detectable by the sensor, wherein calculating the target driving speed includes calculating a third target speed based on the minimum sensing distance and calculating the target driving speed based at least in part on the third target speed;
• setting, by the controller, a preset driving speed as the target driving speed;
• and
• updating, by the controller, the target driving speed when an amount of change in the target driving speed is equal to or greater than a specific value, wherein the amount of change in the target driving speed is obtained according to a change of the target driving speed corresponding to a change of at least one of the weather information, the road surface information, or the minimum sensing distance detectable by the sensor.
