and a danger indicating lamp connected with the intelligent automobile body controller 5 through a hard wire.
The opening mode of the electric backdoor is generally realized by four main modes, namely a car inner backdoor opening button 7, a backdoor outer opening button 3, a remote control key 4, a kick type sensor 12 and the like. The back door opening button 7 is generally arranged near the driver, so that the driver can operate the button conveniently. The back door opening button outside the automobile is generally arranged beside the license plate lamp on the outer side of the back door, so that the operation is convenient and the rain is prevented. The key fob 4 typically has a single button that the user can open the power tailgate by double-clicking or long-pressing.
Wherein, rainfall sensor 2 judges the rainy condition outside the car according to certain frequency to regularly send the data that sense for intelligent automobile body controller 5, intelligent automobile body controller 5 CAN forward the rainy signal that rainfall sensor 2 sent to CAN bus 1 on so that all demand units read.
The back door outside opening button 3 is independently connected with the intelligent automobile body controller 5 through the CAN bus 1, and sends a back door opening request to the intelligent automobile body controller 5.
The low-frequency antenna 6 is a downstream component of the smart vehicle body controller 5, and is configured to operate when a key signal determination request from the smart vehicle body controller 5 is received. The remote control key 4 interacts with the intelligent vehicle body controller 5 through radio frequency signals.
The back door opening button 7 in the vehicle is connected with the back door controller 8 independently, and sends a back door opening request to the back door controller 8.
The back door stay 9 serves as an actuator of the back door controller 8 and responds when an operation request of the back door controller 8 is received.
The combination meter 11 is used as an interactive component between the vehicle and the user, and displays information such as a reminder and the like for the user.
The control method of the electric backdoor control system provided by the invention analyzes the four backdoor opening modes respectively, and performs different responses and prompts in rainy days.
The above system of the present embodiment has the following specific logical functions in specific operations.
When a user opens the backdoor through the backdoor opening button 7 in the vehicle at the position of a driver, the backdoor controller 8 judges whether it rains or not through the signal of the rainfall sensor 2, and if it does not rain, the backdoor is opened normally; if the automobile is raining, the rainfall is fed back to the user through the combination instrument 11, the user is prompted to be raining at present, whether the backdoor needs to be opened or not is confirmed, the user can confirm by pressing the backdoor opening button 7 in the automobile again, and after confirmation, the backdoor controller 8 can respond to the opening of the backdoor. In order to prevent the driver or the user behind the vehicle from forgetting to close the backdoor in time, the system can continuously remind the driver through the combination instrument 11 that the backdoor is opened in rainy days and please close in time, and meanwhile, the backdoor controller 8 can remind the user using the backdoor through intermittent ringing of a buzzer near the backdoor. In addition, in order to prevent poor visual field due to rainy weather, the intelligent vehicle body controller 5 activates double flashing so as to remind pedestrians and vehicles at the front and the rear, thereby achieving the purposes of protecting other people and self-protecting.
As shown in fig. 2, the logic for tailgate opening using the tailgate inside door opening button 7 includes:
in step S101, when the user presses the back door opening button 7 in the vehicle at the driver' S position, the back door controller 8 receives a request for opening the back door.
In step S102, the back door controller 8 reads the rainfall state from the CAN bus 1, and determines whether it is raining.
In step S103, if it is not raining, the back door controller 8 controls the back door stay 9 to perform a normal back door opening response.
In step S104, if it is raining, the back door controller 8 transmits a CAN signal to the combination meter 11 (11).
Step S105, the combination meter 11 prompts the user that the user is raining at present and confirms whether to open the backdoor; the user does not perform the next operation, and the system determines that the driver mistakenly triggers the back door opening button, so that no response is performed. If the user presses the back door opening button 7 again, step S107 is executed.
In step S106, the tailgate controller 8 controls the tailgate stay 9 to open the tailgate to an opening degree of 80% (a first preset opening angle). And simultaneously performs step S107, step S108, and step S109.
In step S107, the back door controller 8 controls the back door buzzer 10 to intermittently sound to remind the user who is using the back door.
Step S108, the back door controller 8 sends a back door opening signal to the intelligent automobile body controller 5 in rainy days, and then the intelligent automobile body controller 5 activates double flashing so as to remind pedestrians and vehicles in front and back;
step S109, the back door controller 8 sends a back door opening signal to the combination instrument 11 in rainy days, and the combination instrument 11 continuously gives out sound and light to warn the driver, for example, sound/text warnings such as "the back door is opened in rainy days, please close in time".
When a user opens the backdoor by pressing the remote control key 4, the intelligent automobile body controller 5 receives a radio frequency signal of the key firstly, the intelligent automobile body controller 5 judges whether it rains or not according to a signal of the rainfall sensor 2, and if the intelligent automobile body controller does not rains, the backdoor is opened normally to respond; if it is raining, the smart car body controller 5 determines whether the key is in the back door area through the low frequency antenna 6 of the keyless system, so as to determine whether the driver actively opens the back door, and if the driver is near the back door, the back door controller 8 responds to open the back door. The back door controller 8 will also alert the driver using the back door by intermittent beeping of a buzzer near the back door. In addition, in order to prevent poor vision due to rainy weather, the intelligent vehicle body controller 5 activates double flashes so as to remind pedestrians and vehicles at the front and the rear, thereby achieving the purpose of protecting other people and self-protection. If intelligent automobile body controller 5 judges through low frequency antenna 6 that the driver is not near the back of the body door, probably there is the driver to open the back of the body door or circumstances such as spurious triggering for other people, be difficult to confirm in detail, consequently, back of the body door controller 8 only opens 50% aperture with the back of the body door through control back of the body door vaulting pole 9, both can reach the user and place/take away article through the back of the body door, also can reduce because of the spurious triggering back of the body door opens the rainwater that causes and drenches into the volume.

In step S204, if it is raining, the smart car body controller 5 determines whether the key fob 4 is within a preset area near the back door through the low frequency antenna 6.
In step S205, if the key fob 4 is within a predetermined area near the tailgate, the tailgate controller 8 controls the tailgate stay 9 to open the tailgate to an opening degree of 80% (a first predetermined opening angle). And simultaneously performs step S207 and step S208.
In step S206, if the remote control key 4 is not in the preset area near the tailgate, the tailgate controller 8 controls the tailgate stay 9 to open the tailgate to an opening degree of 50% (second preset open angle). And simultaneously performs step S207 and step S208.
In step S207, the back door controller 8 sends a signal for opening the back door to the intelligent vehicle body controller 5 in rainy days, and then the intelligent vehicle body controller 5 activates the double flash (hazard indicator) to remind pedestrians and vehicles in front and behind.
In step S208, the back door controller 8 controls the back door buzzer 10 to intermittently sound to remind the user who is using the back door.
When a user opens the backdoor by pressing the backdoor outside opening button 3, the intelligent vehicle body controller 5 receives a request signal of the backdoor outside opening button 3, at this time, the intelligent vehicle body controller 5 firstly determines whether the remote control key 4 is in a backdoor area through the low-frequency antenna 6, and if the key is not in the backdoor area, the situation that the user is not pressing the button and the like may exist, so the backdoor controller 8 does not act. If the remote control key 4 is in the backdoor area, the intelligent automobile body controller 5 reads the rainfall state through the rainfall sensor 2, and if the intelligent automobile body controller does not rain, the intelligent automobile body controller responds by opening the backdoor normally; the back door controller 8 also alerts the user who is using the back door by intermittent beeping of a buzzer near the back door when a response to open the back door is made if it is raining. Simultaneously in order to prevent that the field of vision because rainy weather is not good, back of the body door controller 8 can send the rainy day and open the signal of back of the body door and give intelligent automobile body controller 5, and intelligent automobile body controller 5 can activate two dodges to remind pedestrian and the vehicle of front and back, reach the purpose of protecting other people and oneself's protection.
