Description
- This application claims priority to Korean Patent Application No. 10-2020-0032005, filed on Mar. 16, 2020, which is incorporated herein by reference in its entirety.
- The present disclosure relates to a system and a method for controlling a remote smart parking assist (RSPA) system which assists parking of a vehicle.
- A remote smart parking assist (RSPA) system is a system which assists a driver to conveniently perform parking. In other words, when a driver is exiting the vehicle and operates a remote controller such as a smart key, the RSPA system assists in the parking of the vehicle to even in a small parking space without requiring user intervention.
- However, when the vehicle is parked in a small parking space in which it is difficult for the driver to remain within the vehicle due to restrictions of exiting the vehicle when parked, and requiring the vehicle to be moved again from the small space for the driver the enter the vehicle, there occurs a problem that, when an operation of the RSPA system is impossible due to a system error condition of the vehicle (e.g., an engine warning lamp is turned on), it is impossible for the driver to enter the vehicle and directly drive the vehicle. In other words, if a failure occurs in the vehicle causing failure of the RSPA system, the driver would be unable to access the vehicle.
- A range of the vehicle system error condition is vast. In other words, there is a range in which driving is possible by limiting a performance of the vehicle without influencing the driving of the vehicle. For example, in a situation in which a short distance driving is possible, such as a limp-home mode, the vehicle may be driven but other performance thereof is limited. Therefore, when the vehicle is parked in a space in which the driver is unable to remain within the vehicle for exiting restrictions when parked and then the above system error condition occurs, a situation in which the vehicle is unable to be driven by the RSPA system may occur.
- The contents described in the above are merely to help understanding of the background of the present disclosure and may include what is not previously known to a person of ordinary skill in the art to which the present disclosure pertains.
- An exemplary embodiment of the present disclosure is directed to a system and a method for controlling a remote smart parking assist (RSPA) system, which allow a vehicle to be driven by operating the RSPA system when a vehicle system error in which the vehicle is capable of being driven occurs. Other objects and advantages of the present disclosure can be understood by the following description and become apparent with reference to the embodiments of the present disclosure. Also, it is obvious to those skilled in the art to which the present disclosure pertains that the objects and advantages of the present disclosure may be realized by the means as claimed and combinations thereof.
- In accordance with an exemplary embodiment of the present disclosure, a system for controlling a remote smart parking assist (RSPA) system may include an engine control unit (ECU) configured to operate an engine; and an RSPA controller configured to receive vehicle state information including whether a vehicle system error in which a vehicle is possible to be driven occurs from the ECU and transmit torque request information to the ECU when the vehicle system error in which the vehicle is possible to be driven occurs.
- Further, the system may further include a sensor configured to detect an obstacle around the vehicle, and the ECU may be configured to transmit information received from the sensor to the RSPA controller. The system may further include an electronic stability program (ESP) controller configured to perform vehicle braking control, and when the vehicle system error in which the vehicle is possible to be driven occurs, the RSPA controller may be configured to transmit braking request information to the ESP controller.
- Additionally, the system may include an integrated body unit (IBU) controller configured to transmit input RSPA request information to the RSPA controller, and when the RSPA controller receives the RSPA request information from the IBU controller, the RSPA controller may be configured to determine whether the vehicle system error in which the vehicle is possible to be driven occurs. The vehicle state information may include information regarding whether the RSPA system is used in a previous driving cycle (DC), information regarding the number of attempt times for the RSPA system, and information regarding whether the driver is riding within the vehicle.

-
FIG. 1 is a block diagram illustrating a system for controlling a remote smart parking assist (RSPA) system according to the present disclosure, andFIG. 2 is a diagram illustrating a method of controlling an RSPA system according to the present disclosure. Hereinafter, a system and a method for controlling an RSPA system according to an exemplary embodiment of the present disclosure will be described with reference toFIGS. 1 and 2 . - In accordance with the present disclosure, when a vehicle system error (e.g., battery depletion, system malfunctions within vehicle, or the like) in an allowable range in which a vehicle is possible to be driven occurs, the system and the method for operating an RSPA system determine it is difficult for a driver to operate the vehicle to control the RSPA system. Accordingly, an RSPA
controller 110 and an engine control unit (ECU) 120 may be included in the system, and these may be configured as a single RSPA control device. - Thus, the
RSPA controller 110 may be configured to receive vehicle state information from theECU 120 and operate theECU 120 and an electronic stability program (ESP)controller 220 according to vehicle state information, thereby allowing driving for RSPA. TheESP controller 220 is a controller configured to operate an electronic parking brake (EPB), an electronic stability control (ESC), and the like to operate the RSPA system. - First, the RSPA
controller 110 may be configured to determine whether to perform the RSPA based on input information from the integrated body unit (IBU)controller 210. The IBUcontroller 210 may be a controller in which a body control unit (BCM), a smart key system (SMK), and a tire pressure monitoring system (TPMS) are integrated and configured to communicate with separate controllers for operating wipers, headlamps, and power seats to integrally operate electrical and electronic parts of a vehicle body. In the present disclosure, the IBUcontroller 210 may be configured to receive a signal from asmart key 211 and transmit input information to theRSPA controller 110. - The ECU 120 may be configured to transmit vehicle state information, which includes information received from sensor units such as a sensor, a camera, and a radio detection and ranging (RADAR) 230, to the
RSPA controller 110. When a vehicle system error in which the vehicle is possible to be driven is detected (e.g., a vehicle system error is detected but the vehicle is determined to still be capable of being driven), theRSPA controller 110 may be configured to determine whether to operate the RSPA based on the input information from theIBU controller 210 and the vehicle state information from theECU 120. Consequently, when the RSPA system is applied and operated, torque request information may be transmitted to theECU 120, and braking request information may be transmitted to theESP controller 220 to thus drive the vehicle. Thus, theECU 120 may be configured to perform air volume control and ignition angle control, and theESP controller 220 may be configured to perform braking control. - The vehicle state information, which the
RSPA controller 110 receives from theECU 120 for the above controls, may include information regarding whether a vehicle system error occurs, information regarding whether a corresponding vehicle system error is a vehicle system error in an allowable range in which the vehicle is possible to be driven, information regarding whether an RSPA system is used in a previous driving cycle (DC), information regarding whether a surrounding obstacle is detected based on surrounding space recognition information from thesensor 230, information regarding the number of attempt times for the RSPA system, and information regarding whether the driver is present within the vehicle. - Thus, in a situation in which a vehicle system error in which the vehicle is possible to be driven, the RSPA system is used in the previous DC, the surrounding obstacle is detected, the number of attempt times for the RSPA system is less than a set value, or the driver is not detected to be present within the vehicle, the RSPA system may be allowed or operated to control the
ECU 120 and theESP controller 220 to thus drive the vehicle. The determination of whether the driver is present within the vehicle by theECU 120 may be performed by determining whether a seat belt is engaged, whether a seat weight greater than a predetermined threshold is detected, whether a pedal is engaged, or whether other buttons related to vehicle functions within the vehicle are operated or manipulated. - Referring to
FIG. 2 , a method of controlling an RSPA system according to the present disclosure will be described. First, when an RSPA system is requested by the driver (S11), whether a vehicle system error occurs may be determined (S12). RSPA system request information by the driver may be determined based on input information from theIBU controller 210 due to an operation such as thesmart key 211 or the like. TheRSPA controller 110 may be configured to determine whether the vehicle system error occurs based on the vehicle state information received from theECU 120. - Further, the
RSPA controller 110 may be configured to determine whether the occurred vehicle system error is an error within an allowable range (S13). The vehicle system error in the allowable range refers to an error in a state in which the vehicle is possible to be driven. In other words, the vehicle system error corresponds to a limp-home mode in which a vehicle may be driven by removing an influence on actual vehicle driving or limiting vehicle performance. Then, theRSPA controller 110 may be configured to determine whether the RSPA system is used in the previous DC or the surrounding obstacle is detected (S14). - When the RSPA system is used in the previous DC, the vehicle may be difficult to be driven when the RSPA system is not used, and, this may be determined as a condition in which, when the surrounding obstacle is not detected, the vehicle may be possible to be driven without allowing the RSPA system.
- As described above, when the RSPA system is determined as being required, the
RSPA controller 110 may be configured to determine a situation whether the RSPA system should be allowed based on the number of attempt times for the RSPA system and the detection whether the driver is present within the vehicle (S15). In other words, theRSPA controller 110 may be configured to determine whether the RSPA system should be allowed. In particular, when the number of attempt times for the RSPA system is greater than or equal to the set value, excessive use of the RSPA system may be restricted, and, when the driver is detected as being present within the vehicle, the driver may be determined to be in a state of being capable of driving the vehicle and thus, the use of the RSPA system may be restricted. For example, the set value may be three times. - As described above, when the vehicle system error in which the vehicle is possible to be driven occurs as the determination result in S13, the RSPA system is used in the previous DC or the surrounding obstacle is detected as the determination result in S14, and the number of attempt times for the RSPA system is less than the set value and the driver is determined as not being present within the vehicle as the determination result in S15, the
RSPA controller 110 may be configured to operate the RSPA system in S16, transmit the torque request information to theECU 120, and transmit the braking request information to theESP controller 220. - However, when the vehicle system error in which the vehicle is possible to be driven does not occur as the determination result in S13, the RSPA system is not used in the previous DC or the surrounding obstacle is not detected as the determination result in S14, and the number of attempt times for the RSPA system is greater than or equal to the set value and the driver is determined as being present within the vehicle as the determination result in S15, the
RSPA controller 110 may be configured to restrict operation of the RSPA system. - In accordance with the present disclosure, whether a driver is in a situation in which it is difficult for the driver to move a vehicle during parking may be determined, and, when a system error in an allowable range occurs, the vehicle may be driven using a remote smart parking assist (RSPA) system to thus increase driver convenience.
- While the present disclosure has been described with respect to the specific embodiments, it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the present disclosure as defined in the following claims. Accordingly, it should be noted that such alternations or modifications fall within the claims of the present disclosure, and the scope of the present disclosure should be construed on the basis of the appended claims.
