Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a vehicle control method in a parking process, which is applied to a parking system, wherein the parking system can be an automatic parking system or a remote control parking system, and the invention is not limited in particular. Taking an application scenario of a remote control parking system as an example, the remote control parking system may include a remote control parking controller (RPA) and a vehicle control device (BCM), where the BCM is deployed in a vehicle, a user controls a parking process of the vehicle through the RPA to enable the vehicle to enter a parking space, and the BCM is configured to control the vehicle to enter a certain state of the parking process according to various indication signals sent by the remote control parking, so that the parking process is safer, and accidents are reduced. It should be noted that, when the parking system is an automatic parking system, the BCM may also receive various indication signals sent by the automatic parking system to control the vehicle to enter a certain state of the parking process. The following describes in detail a vehicle control method for a parking process provided in the present invention, taking an application scenario of a remote control parking system as an example.
Referring to fig. 1, in an embodiment, a vehicle control method is described, which includes the following steps:
s101: the user starts the RPA so that the RPA enters a parking space searching state and sends a corresponding parking space searching state signal to the BCM.
S102: the BCM detects whether a parking space searching state signal is received or not;
s103: if the BCM receives the parking space searching state signal, the prompt device of the vehicle is controlled to send out a prompt signal corresponding to the parking space searching state, and an unlocking signal is sent out to enable the vehicle to be in a man-made driving state.
In the remote control parking system, when a user needs to park a vehicle, the vehicle needs to be stopped, so that the user can start the RPA and control the parking process of the vehicle through the RPA. After the user starts the RPA, the RPA enters a parking space searching state and sends a corresponding parking space searching state signal to the BCM so as to enter a parking space searching process. For the BCM, the BCM detects whether the received parking space searching state signal is received in real time, if the parking space searching state signal sent by the RPA is received, it indicates that the user needs to remotely control parking through the RPA, and at this time, the BCM controls a prompting device of the vehicle to send a prompting signal corresponding to the parking space searching state, and sends an unlocking signal to enable the vehicle to be in a manually drivable state.
The prompting device of the vehicle is a device which is deployed on the vehicle and used for prompting the current parking space searching state, the prompting signal corresponding to the parking space searching state is used for indicating that the current vehicle is in the parking space searching state, namely indicating that the vehicle enters a remote control parking process, and the position of the vehicle in the remote control parking state can be indicated to the outside by sending the prompting signal corresponding to the parking space searching state so as to remind surrounding personnel.
It should be noted that after the driver leaves the vehicle, the vehicle is usually in a non-unlocked state for safety, that is, the user needs to enter the vehicle by a key or the like to manually control the vehicle. It can be seen that embodiments of the present invention provide a method of controlling a vehicle during parking, in which, when the BCM receives the parking space searching state signal, the parking space searching state in the parking process is shown, and except for sending out a prompt signal corresponding to the parking space searching state, an unlocking signal is also sent to the vehicle to enable the vehicle to be in an unlocking state, namely the vehicle is in a man-made driving state, by sending out a prompt signal corresponding to the parking space searching state, the outside can know whether the vehicle is in the autonomous driving state or the remote control parking state, meanwhile, through the unlocking signal, when the vehicle breaks down suddenly, the user can be effectively ensured to obtain the vehicle control right at the highest speed so as to avoid risks, the user can be ensured to open the door of the vehicle at any time in the remote control parking process so as to manually drive the vehicle to deal with emergency situations, and the safety of the parking process is improved.
In an embodiment, in step S103, controlling the prompting device of the vehicle to send a prompting signal corresponding to the parking space searching state means lighting a position lamp of the vehicle as the prompting signal corresponding to the parking space searching state to prompt the current position of the vehicle. The specific form of lighting is not limited in the present invention, and may be, for example, normally lighting or flashing. Therefore, the existing position lamp of the vehicle is directly used as a prompting device to send out a prompting signal corresponding to the parking space searching state, the state prompting cost is reduced, and the vehicle parking space prompting device is simple and easy to use. Of course, other manners of sending the prompt signal corresponding to the parking space searching state may also be used, for example, an external prompt device may be deployed outside the vehicle, for example, the prompt signal corresponding to the parking space searching state is sent through a screen, and the like, which is not limited specifically.
In an embodiment, as shown in fig. 2, in step S103, after the BCM controls the prompting device of the vehicle to send out the prompting signal corresponding to the parking space searching state, the method further includes the following steps:
s104: and the RPA detects whether the parking system is in a system fault state in real time.
S105: if the RPA detects that the parking system is in a system fault state, the RPA sends a system fault state signal to the BCM;
s106: and the BCM controls a prompting device of the vehicle to send out a prompting signal corresponding to the system fault state, and sends out the unlocking signal again to ensure that the vehicle is in an artificial driving state.
With respect to steps S104-S106, it can be understood whether the parking system is operating safely, and the influence on whether the parking process is safe and successful is large. The faults of the parking system generally comprise RPA faults and/or BCM faults, or communication faults between the RPA and the BCM, and the like, and the BCM and/or the RPA can detect whether the parking system has faults in real time, so that whether the parking system is in a system fault state or not can be judged. In this embodiment, when the prompt device of the BCM controls the vehicle to send a prompt signal corresponding to the parking space searching state, the RPA has already entered the parking space searching state, and in the process of the parking space searching state, when the RPA detects that the parking system has a system fault, the RPA needs to send a system fault state signal to the BCM, so that the BCM determines that the parking system is in the system fault state according to the system fault state signal, and after the BCM detects that the parking system is in the system fault state, the BCM controls the prompt device of the vehicle to send a prompt signal corresponding to the system fault state, and sends the unlocking signal again to ensure that the vehicle is in the artificial driving state.
In an embodiment, the step of controlling the vehicle to send out the prompt signal corresponding to the system fault state refers to controlling a horn of the vehicle to send out a system fault prompt sound according to a preset alarm sound. The specific form of the preset alarm sound is not limited in the present invention, and for example, the preset alarm sound may be a sound of dropping in sequence according to a preset frequency, or a sound of dropping may be kept being sent until the user turns off the alarm sound actively. Therefore, the existing horn of the vehicle is directly used as a prompting device to send out a prompting signal corresponding to the system fault state, so that the state prompting cost is reduced, and the method is simple and easy. It should be noted that other manners for sending the prompt signal corresponding to the system fault state may also be used, for example, an external prompt device may be deployed outside the vehicle, for example, the prompt signal corresponding to the system fault state is sent through a screen, and the like, which is not limited specifically.
On one hand, after the parking space searching state is entered, when a parking system fails, the prompting device of the vehicle is controlled to send a prompting signal corresponding to the system failure state, and the unlocking signal is sent again to ensure that the vehicle is in an artificial driving state, so that the vehicle is always in driving control of a user who can enter the parking space searching process in the parking space searching process, the safety of the parking space searching process is improved, and the possibility of accidents is greatly reduced.
In an embodiment, after step S104, if the BCM receives a system fault status signal sent by the RPA, the method further includes the following steps:
s107: and the BCM closes the prompt signal corresponding to the parking space searching state.
In this embodiment, after the RPA enters the parking space searching state, if a system fault occurs, the BCM controls the prompting device of the vehicle to send out a prompting signal corresponding to the system fault state, and sends out the unlocking signal again to ensure that the vehicle is in the state of being manually driven, and besides, the BCM also closes the originally sent prompting signal corresponding to the parking space searching state to reduce power consumption.
In one embodiment, as shown in fig. 3, in S104, that is, after the RPA detects whether the parking system is in the system fault state in real time, the method further includes the following steps:
s108: and if the RPA does not detect that the parking system is in the system fault state, the RPA determines whether to find the parking space.
S109: and if the RPA determines that the parking space is found, the RPA enters a parking state and sends a parking state entering signal to the BCM.
S110: and if the RPA does not find the parking space, sending a parking ending state signal to the BCM.
For steps S108 to S110, if the RPA does not detect that the parking system is in the system failure state, the RPA may search for a parking space, thereby improving the safety of subsequent parking. And if the RPA determines to find the parking space, the RPA enters a parking state and sends a signal of entering the parking state to the BCM so as to execute the subsequent parking process. If the RPA does not find the parking space, which indicates that the parking state condition is not met at the moment, a parking state ending signal is sent to the BCM so as to end the parking operation.
In an embodiment, as shown in fig. 4, if the BCM receives a parking space searching status signal, the method further includes the following steps:
s111: if the BCM receives a parking state entering signal, the prompt device for keeping the vehicle sends a prompt signal corresponding to the parking space searching state and keeps the vehicle in an artificial driving state, and the prompt device for controlling the vehicle sends a prompt signal corresponding to the parking state entering state.
With respect to step S111, it is understood that after the RPA determines that a parking space is found, the RPA may enter a parking state and send a parking state entry signal to the BCM. For the BCM, the BCM detects whether a parking entering state signal is received, if the BCM receives a parking space searching state signal sent by the RPA, it indicates that the RPA has entered a parking state, that is, a parking process has been entered, and if the BCM does not receive the parking space searching state signal sent by the RPA, it indicates that the RPA has not entered the parking state, and at this time, the BCM keeps waiting for an indication signal of the RPA.
If the BCM receives the parking state entering signal, the BCM keeps the prompting device of the vehicle to send out a prompting signal corresponding to the parking space searching state and keeps the vehicle in the man-made driving state, and controls the prompting device of the vehicle to send out a prompting signal corresponding to the parking state entering state. Therefore, in the embodiment, the prompt signal corresponding to the parking space searching state sent after the parking space searching state is continuously kept, and the vehicle is kept in the artificial driving state. The method can effectively ensure that the user can still enter the vehicle to control the vehicle after entering the parking state, further ensure the safety problem and strengthen the controllability, and simultaneously, the prompting device for controlling the vehicle sends out a prompting signal corresponding to the entering of the parking state so as to prompt that the current vehicle is in a normal driving state without artificial driving.
In one embodiment, in step S111, the prompting device for controlling the vehicle sends out a prompting signal corresponding to entering a parking state, that is, a low beam light and a warning light of the vehicle are turned on as the prompting signal corresponding to entering the parking state. The lighting mode is not limited in the present invention, and may be, for example, a mode in which the low beam light and the warning light are controlled to be constantly on or flash. It is thus clear that here has directly used present dipped headlight of vehicle and warning light to send the prompt signal that seeks the parking stall state and correspond as the suggestion device, has reduced the state suggestion cost, and is also fairly simple and easy, and the dipped headlight can also play the effect of auxiliary lighting in the position process of subsequently parking, and the warning light can be used to the suggestion current vehicle is in the normal driving state of non-artificial driving, has improved the practicality of scheme. Of course, other manners for sending the prompting signal corresponding to the parking entering state may also be used, for example, an external prompting device may be deployed outside the vehicle, for example, the prompting signal corresponding to the parking entering state is sent out by a screen or a combination of lights, and the like, which is not limited specifically.
In one embodiment, as shown in fig. 4, after step S109, that is, after the RPA enters the parking state, the method further includes:
s112: and the RPA detects whether the parking system is in a system fault state in real time.
S113: if the RPA detects that the parking system is in a system fault state, the RPA sends a system fault state signal to the BCM;
s114: and the BCM controls a prompting device of the vehicle to send out a prompting signal corresponding to the system fault state, and sends out the unlocking signal again to ensure that the vehicle is in an artificial driving state.
As for steps S112 to S114, it can be understood that, in this embodiment, when the prompt device that the BCM controls the vehicle sends the prompt signal corresponding to the parking entering state, the RPA already enters the parking state, and the RPA also has a possibility of a fault occurring during the parking process, so that during the parking process, the RPA still continues to detect the system fault, when the RPA detects that the parking system has the system fault, the RPA needs to send a system fault state signal to the BCM, so that the BCM determines that the parking system is in the system fault state according to the system fault state signal, and after the BCM detects that the parking system is in the system fault state, the BCM controls the prompt device of the vehicle to send the prompt signal corresponding to the system fault state, and sends the unlocking signal again to ensure that the vehicle is in the driveable state.
In an embodiment, after step S112, if the BCM receives a system fault status signal sent by the RPA, the method further includes the following steps:
s115: and the BCM closes the prompt signals corresponding to the parking space searching state and the parking entering state.
In this embodiment, after the RPA enters the parking state, if a system fault occurs, the BCM controls the prompting device of the vehicle to send out a prompting signal corresponding to the system fault state, and sends out the unlocking signal again to ensure that the vehicle is in the state of being manually driven, and besides, the BCM also closes the originally sent prompting signal corresponding to the parking space searching state and the prompting signal corresponding to the parking state, so as to reduce power consumption.
In one embodiment, after the prompting device controlling the vehicle sends out a prompting signal corresponding to entering the parking state, the method further includes the following steps:
s116: and if the BCM receives a parking ending signal, closing the prompt signal corresponding to the parking space searching state, and closing the prompt signal corresponding to the parking entering state.
After the prompting device for controlling the vehicle sends out a prompting signal corresponding to the parking state, the RPA can perform a remote parking process, which is not described in detail herein. After the RPA finishes parking, a parking ending state signal can be sent to the BCM, if the parking ending state signal is received, the BCM closes the prompt signal corresponding to the parking space searching state and closes the prompt signal corresponding to the parking entering state, and therefore the parking process is finished.
It should be noted that, in an embodiment, in step S111, after the prompting device controlling the vehicle sends the prompting signal corresponding to the parking entering state, if the parking ending state signal is not received within the first preset time period, which indicates that the parking has not been completed for some reason, the prompting signal corresponding to the parking entering state is turned off, so as to avoid excessive power consumption loss. The specific duration of the first preset duration is not limited in the present invention, and the first preset duration may be, for example, 10 minutes, 11 minutes, and the like.
In an embodiment, in step S104 or S112, if it is detected that the parking system is in the system failure state, all prompting signals sent by the prompting device of the vehicle are turned off after a second preset time period. The specific duration of the second preset duration is not limited in the present invention, and the second preset duration may be, for example, 5 seconds, 10 seconds, and the like.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
