The method includes determining whether or not a valet mode entry condition may be satisfied, determining a plurality of driving evaluation factors for valet parking based on at least one of a vehicle status or a driving environment, upon determining that the valet mode entry condition may be satisfied, calculating a valet driving evaluation score by analyzing the determined driving evaluation factors and collecting result values acquired through analysis, and displaying the calculated valet driving evaluation score. ## Claims ### Claim 1 A method for evaluating valet mode driving of a vehicle, the method comprising: determining whether or not a valet mode entry condition is satisfied; determining a plurality of driving evaluation factors for valet parking based on at least one of a vehicle status or a driving environment, upon determining that the valet mode entry condition is satisfied; calculating a valet driving evaluation score by analyzing the determined driving evaluation factors and collecting result values acquired through analysis; and displaying the calculated valet driving evaluation score. ### Claim 2 (depends on 1) The method according to claim 1, further comprising guiding the valet parking so as to allow the valet driving evaluation score to reach a high score. ### Claim 3 (depends on 2) The method according to claim 2, wherein different weights predetermined depending on the plurality of determined driving evaluation factors are applied to the respective driving evaluation factors. ### Claim 4 (depends on 1) The method according to claim 1, wherein the plurality of driving evaluation factors comprises at least one of impulse of the vehicle, sudden acceleration and sudden braking, a driving distance of the vehicle, a frequency of turning-on of an engine of the vehicle, a frequency of gear shifts of the vehicle, or shaking of the vehicle. ### Claim 5 (depends on 4) The method according to claim 4, wherein the impulse of the vehicle is extracted or calculated using at least one of a wheel speed change of the vehicle, a difference between a wheel speed and an acceleration sensor value of the vehicle, or a pitch rate. ### Claim 6 (depends on 1) The method according to claim 1, wherein, in the calculating the valet driving evaluation score, the valet driving evaluation score is continuously calculated until the valet parking has been completed. ### Claim 7 (depends on 1) The method according to claim 1, wherein, in the displaying the calculated valet driving evaluation score, the calculated valet driving evaluation score is compared with a predetermined evaluation score, and a warning notification is output and is transmitted to a smart device of a vehicle owner, when the calculated valet driving evaluation score is less than the predetermined evaluation score. ### Claim 8 (depends on 2) The method according to claim 2, wherein, upon determining that the valet mode entry condition is satisfied, an emergency braking apparatus, a Blind Spot Detection (BSD) system, a lane departure warning system, or safety assistance systems and functions are controlled to be activated based on the vehicle status or the driving environment in a valet mode. ### Claim 9 (depends on 1) A non-transitory computer readable recording medium having recorded thereon a program to execute the method according to claim 1. ### Claim 10 An apparatus for evaluating valet mode driving of a vehicle, the apparatus comprising: an entry determiner configured to determine whether or not a valet mode entry condition is satisfied; an evaluation factor determiner configured to determine a plurality of driving evaluation factors for valet parking based on at least one of a vehicle status or a driving environment, upon determining that the valet mode entry condition is satisfied; a controller comprising an evaluation score calculator configured to calculate a valet driving evaluation score by analyzing the determined driving evaluation factors and collecting result values acquired through analysis; and a display configured to display the calculated valet driving evaluation score. ### Claim 11 (depends on 10) The apparatus according to claim 10, wherein the controller further comprises a driving guide unit configured to guide the valet parking so as to allow the valet driving evaluation score to reach a high score. ### Claim 12 (depends on 11) The apparatus according to claim 11, wherein different weights predetermined depending on the plurality of determined driving evaluation factors are applied to the respective driving evaluation factors. ### Claim 13 (depends on 10) The apparatus according to claim 10, wherein the plurality of driving evaluation factors comprises at least one of impulse of the vehicle, sudden acceleration and sudden braking, a driving distance of the vehicle, a frequency of turning-on of an engine of the vehicle, a frequency of gear shifts of the vehicle, or shaking of the vehicle. ### Claim 14 (depends on 13) The apparatus according to claim 13, wherein the impulse of the vehicle is extracted or calculated using at least one of a wheel speed change of the vehicle, a difference between a wheel speed and an acceleration sensor value of the vehicle, or a pitch rate. ### Claim 15 (depends on 10) The apparatus according to claim 10, wherein the evaluation score calculator continuously calculates the valet driving evaluation score until the valet parking has been completed. ### Claim 16 (depends on 10) The apparatus according to claim 10, wherein the display outputs a warning notification and transmits the warning notification to a smart device of a vehicle owner, when the calculated valet driving evaluation score is less than a predetermined evaluation score. ### Claim 17 (depends on 11) The apparatus according to claim 11, wherein the evaluation factor determiner activates an emergency braking apparatus, a Blind Spot Detection (BSD) system, a lane departure warning system, or safety assistance systems and functions based on the vehicle status or the driving environment in a valet mode, upon determining that the valet mode entry condition is satisfied.
