It should be noted that the terms "first" and "second" in the description of the present invention are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Fig. 1 is a schematic flowchart of a method for preventing pinching of a window of an automobile based on a domain controller architecture according to an embodiment of the present disclosure.
In this embodiment, the domain control framework includes a domain controller and a domain controller, the domain controller is connected to at least the window driving device and the domain controller, the domain controller is connected to the window driving device in a hard-wired manner, and the domain controller is configured to control the window driving device to operate.
In this embodiment, the hard-wired method generally refers to: the automobile field generally refers to a mode of directly connecting and transmitting current by using a common wire harness as a 'hard wire' mode, which means that a physical current analog quantity is directly used for driving related equipment.
In this embodiment, the zone controller may also be connected to other devices, for example, the zone controller may also be connected to a vehicle door.
The automobile window anti-pinch method based on the domain controller architecture shown in fig. 1 comprises the following steps:
step 101: the zone controller acquires a foreign matter signal;
step 102: the region controller generates an anti-clamping signal according to the foreign matter signal and transmits the anti-clamping signal to the car window driving device and the region controller;
step 103: and the area controller stops sending a control instruction to the area controller after acquiring the anti-clamping signal or ignores the control instruction sent by the area controller after the anti-clamping signal.
The automobile window anti-pinch method based on the domain controller framework has the following advantages:
1. the anti-pinch device comprises a zone controller, a window driving device and a control device, wherein the zone controller is used for generating an anti-pinch signal and transmitting the anti-pinch signal to the window driving device, so that the window driving device can perform anti-pinch action according to the anti-pinch signal, and the zone controller is connected with the window driving device in a hard line mode, so that the required response precision can be achieved, and the transmission of the low-delay anti-pinch signal is realized.
2. The control instruction is sent to the zone controller through the zone controller to realize the control of the zone controller, so that the centralized control of the zone controller is realized under the condition of meeting the response precision.
In this embodiment, the method for preventing vehicle window from being pinched based on the domain controller architecture further includes:
the zone controller acquires an action signal fed back by the anti-clamping action of the car window driving device after receiving the anti-clamping signal;
the zone controller judges whether to generate an anti-pinch finishing signal according to the action signal, if so, the zone controller generates an anti-pinch finishing signal
The zone controller generates an anti-pinch end signal.
For example, the window driving device is a hall motor, and when the hall motor is in normal operation, the high and low levels of hall signal pulses are fed back to the zone controller at a specified period (i.e. the fed-back action signal), and once a foreign object is jammed or clamped, the hall signal period is prolonged, and if the motor is completely jammed, the hall signal will not change.
Therefore, through judging the action signal to the feedback, can judge whether the centre gripping arrives the foreign matter, when the motor centre gripping arrived the foreign matter, the pulse that hall motor sent can be abnormal, and receives as hall motor prevent pressing from both sides behind the clamping signal, can reverse, carry out the reversal in-process, the pulse that hall motor sent can return normal condition, at this moment, can be in order to judge for preventing pressing from both sides the completion signal, can be in order to generate and prevent pressing from both sides the completion signal.
In this application, it specifically adopts the regional controller to stop sending control instruction to the regional controller after obtaining anti-centre gripping signal or adopt the regional controller to ignore the regional controller and be in the mode of the control instruction that sends behind the anti-centre gripping signal can decide by oneself according to user's needs, specifically speaking, the decision right of adopting the mode of ignoring or adopting the mode of stopping sending control instruction can be at the regional controller, also can be at the regional controller. For example, if the decision right is in the domain controller, a flag bit can be used to limit whether the domain controller has the right to send the control command; if the negotiation process is at the zone controller, the zone controller may continue to send instructions as intended by the user, but the zone controller has the right to ignore based on actual conditions.

In this embodiment, whether the action signal that feeds back through window drive arrangement judges to generate and prevents pressing from both sides the end signal, has accomplished whole anti-pinch protection promptly. For example, the hands of the user at the passenger seat are already clamped by the window, but the user at the passenger seat continues to press the button for continuously lifting the window due to confusion, at this time, the domain controller stops sending the control command to the domain controller after receiving the anti-clamping signal, so that even in a dangerous situation, the signal that the user wants to lift the glass cannot be transmitted to the domain controller through the domain controller, and the glass cannot be lifted, therefore, the domain controller needs to be informed by generating the anti-clamping completion signal, so that the domain controller resumes sending the command to the domain controller according to the anti-clamping completion signal.

and the zone controller controls the car window driving device to work according to the automatic lifting signal.
At door window drive arrangement in operation, the door window can rise according to door window drive arrangement's control, and the door window presss from both sides the foreign matter when rising to preventing pressing from both sides the region, then door window drive arrangement can transmit for region controller with the foreign matter signal, and region controller obtains behind this foreign matter signal and prevents pressing from both sides according to the foreign matter signal generation and will prevent pressing from both sides the signal transmission and give door window drive arrangement and region controller.
In this embodiment, the control logic of the window driving apparatus is provided in a zone controller, and the zone controller controls the window driving apparatus in accordance with a signal of the zone controller, only when the foreign matter is judged and the anti-pinching signal is generated, by the zone controller.
