Although the CAN protocol is a general protocol on an automobile, specific message contents are different from manufacturers and are proprietary protocols, and are not public. Therefore, from legal significance, monitoring the content of the CAN message using the original vehicle requires the authorization of a manufacturer, and the monitored information may only be the embodiment of the real information in a certain state, and the real information may not be reflected in other states. The additional equipment directly sends the CAN message, the CAN message cannot be authorized by an automobile manufacturer, the CAN communication system of an original automobile is easy to damage, and the report that the CAN network of the original automobile is abnormal due to the fact that the additional equipment is privately installed is revealed in a public information display mode.
The CAN protocols of each type of vehicle or vehicles of the same type of vehicle in different years are not completely the same, so that the situations of misjudgment and mistrigger when an old program is used for a newly delivered vehicle type exist, the additional equipment or the vehicle CAN network is abnormal in work, and if the additional equipment or the vehicle CAN network cannot be updated in time, great hidden danger exists.
The product of the electric tail gate has the requirement of acquiring whether the vehicle is in a running state, so that the patent provides a method for not damaging a CAN network and not damaging the original vehicle wiring harness. The method is also suitable for other additionally-installed equipment
Example 1
The ripple detection circuit judges whether the vehicle is in a starting state or not without connecting a CAN network or a newly added physical connecting line.
As shown in figure 2, when the vehicle is in a flameout state, the voltage of the automobile battery is less than 12.6V, the voltage of the battery does not change obviously when an electric appliance on the vehicle is used, and voltage ripples can not be generated for a long time, so that the voltage waveform of the automobile battery in the flameout state is stable and clean. After the vehicle starts, the automobile generator also starts to work synchronously, because the generator is always charging the storage battery, the voltage of the storage battery at the moment is generally between 13V and 15V, and because the generator is driven by the automobile engine, the working rotating speed is unstable, and a plurality of heavy-current devices work on the vehicle, the voltage waveform of the storage battery at the moment has a plurality of ripples, and the automobile can be effectively judged to be in a starting state through the change of the voltage and the ripples. Therefore, through the innovation point, the automobile tail gate control device does not need to be connected with a CAN (controller area network) line or an ACC (automatic control center) detection line (the ACC detection line is a voltage change signal indicating that the automobile is in a starting state), and only needs to judge the power supply voltage of the device, so that the installation time is saved, and the phenomenon that the original automobile circuit is failed due to the wrong connection is avoided.
Example 2
The speed and the inclination angle of the vehicle are judged by the acceleration sensor without connecting a CAN network.
As shown in fig. 3, the acceleration sensor is a sensor that can measure the acceleration of the object, and can also determine the inclination angle of the vehicle when the sensor is in a stationary state. Taking a 3-axis acceleration sensor as an example, the 3-axis acceleration sensor can measure X, Y, Z accelerations in three directions, when the vehicle is in a flameout stop state, the vehicle does not move or vibrate, the 3-axis acceleration sensor has stable accelerations in three axes, when the vehicle is on a flat road, only the acceleration in the direction perpendicular to the earth (Z axis) is provided, and the acceleration in two axes (X, Y axis) parallel to the road surface is not provided. When the vehicle is stopped on a slope, the X, Y, Z axle will have an acceleration, and the vehicle's inclination angle can be calculated. Therefore, when the vehicle is in the middle of traveling, the acceleration sensor can always detect the changing speed due to vibration, acceleration, braking, and the like of the vehicle, and thus it can be effectively determined that the vehicle is in a traveling state. When the vehicle is on a slope, the inclination angle of the vehicle can be judged, so that the proper door opening and closing parameters can be adjusted.
Example 3
And a time-sharing multiplexing technology of the motor driving circuit is used, so that 1 motor driving circuit is saved.
As shown in fig. 4, each motor generally needs 1 motor driving circuit to drive, and in the prior art solution on the market, 3 motor driving circuits are also used to drive 2 strut motors and 1 electric attraction lock. According to the control logic of the electric tail gate, when the tail gate is opened, the electric suction lock is operated to enable the gate to be pushed out for a short distance, then the stay bar is used for lifting the gate, when the tail gate is closed, the stay bar is used for lowering the gate to the buckling lock block, then the electric suction lock is used for tensioning the gate, and the electric suction lock and the operation of the stay bar can be found to be separated and not repeated, so that the brushless motor 2 of the stay bar 2 and the electric suction lock are controlled by using 1 channel switching circuit, namely 1 relay and a control circuit thereof. Specifically, when the door is opened, the circuit of the motor driving circuit 2 is connected to the electric suction lock through the relay, so that the electric suction lock operates, and then the relay is switched to connect the circuit of the brushless motor 2 of the stay bar 2, so that the stay bar 2 is lifted. When the door is closed, the relay switches the circuit of the brushless motor 2 of the support rod 2, then the support rod 2 descends until the door is closed, and then the relay is switched to the circuit of the electric suction lock, so that the electric suction lock tightens the tail door. Therefore, by the control method, the control of the stay bar motor and the electric suction lock can be realized through 1 motor driving circuit, 1 motor driving circuit is saved, and the cost is effectively reduced.
Example 4
A brushless motor and a drive circuit are used. The prior art scheme generally uses a direct current brush motor as a driving motor of a stay bar, and the direct current brush motor has the characteristics of simple structure, mature technology, low cost and the like, but also has the defects of short service life of a carbon brush, large electromagnetic interference when the motor rotates, large noise and the like. This patent has used DC brushless motor as vaulting pole driving motor, makes the motor work in suitable scope through software speed governing, and although software control can be more complicated, the degree of difficulty is bigger, but can effectively reduce motor pivoted sound, also do not have electromagnetic interference.
Example 5
And the Internet of things module is used for man-machine interaction. Present automobile-used spare part is more and more intelligent, carry out intercom through the CAN agreement between the original automobile spare part, main spare part that slowly develops into the car now needs and cell-phone, cloud platform communication, consequently this device has been equipped with the thing networking module, through WIFI, near field communication module such as bluetooth is connected with the cell-phone, also CAN be through remote communication module such as GPRS and cell-phone, the cloud platform is connected, allow the user to look over the state of this device and set up relevant parameter through the cell-phone through multiple mode, let the user accomplish anytime and anywhere's control.
