Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A control method of a vehicle, a master controller, a slave controller, and a control system of a vehicle according to embodiments of the present invention are described below with reference to the accompanying drawings.
Fig. 1 is a system architecture diagram in which a control method of a vehicle according to one embodiment of the present disclosure may be implemented. As shown in fig. 1, the system 100 includes: a master controller 11 and at least one slave controller 12; the master controller 11 and the slave controller 12 communicate with each other through a network 13. In this embodiment, the network 13 may be a wired network or a wireless network; the wired network may be, but is not limited to, an ethernet network, a CAN network, and the like, and the wireless network may be, but is not limited to, bluetooth, 3G, 4G, 5G, and the like.
In the system 100, the master controller 11 sends a wake-up request message to the slave controllers in advance before the ignition start of the vehicle, so as to wake up at least part of the slave controllers 12, and the awakened slave controllers 12 can monitor the state of the vehicle in advance, so that the vehicle can have sufficient time to monitor the state of the whole vehicle before the start, and the start preparation is made, thereby improving the start performance and safety of the vehicle.
Fig. 2 is a flowchart illustrating a control method of a vehicle according to an embodiment of the disclosure. As shown in fig. 2, the control method of the vehicle according to the present embodiment includes the following steps at the main controller side:
and S101, detecting an ignition signal of the vehicle by the main controller when the unlocking or opening of the vehicle door is recognized.
Generally, when the ignition of the vehicle is started, the vehicle controller of the vehicle acquires an ignition signal of the vehicle. Further, the vehicle control unit can send the ignition signal to the main controller after acquiring the ignition signal of the vehicle, so that the main controller can receive the ignition signal and further detect the ignition signal. In this embodiment, when it is recognized that the vehicle door is unlocked or opened, the main controller may detect an ignition signal of the vehicle according to communication information between the main controller and the vehicle control unit.
And S102, if the ignition signal is not detected, the master controller sends a wake-up request message to the slave controller so that the slave controller enters a wake-up state after receiving the wake-up request message.
Specifically, when the main controller recognizes that the ignition signal is not detected, that is, the vehicle control unit does not send the ignition signal to the main controller, it may be determined that the vehicle is not ignited to start. At this time, in order to enable the vehicle to have sufficient time to monitor the state of the whole vehicle before starting and prepare for starting, the master controller may send a wake-up request message to the slave controller, so that the slave controller enters a wake-up state after receiving the wake-up request message, that is, at least part of the slave controller is woken up, so that the awakened slave controller can monitor the state of the vehicle in advance, and further, the starting performance and safety of the vehicle are improved.
Optionally, when the wake-up request message is sent to the slave controller, the slave controller may be activated first and then the wake-up request message is sent. As shown in fig. 3, the method comprises the following steps:
s201, intermittently or continuously sending an activation instruction to the slave controller so as to enable the slave controller to enter an activation state.
Specifically, when the activation instruction is sent, the activation instruction may be intermittently sent to the slave controller, so that the slave controller enters an activation state after receiving the activation instruction, and the energy consumption of the master controller is reduced.
In addition, the slave controller may also select to continuously send the activation instruction to make the slave controller enter an activation state after receiving the activation instruction, which may be determined according to an actual situation, and is not limited herein.
Alternatively, whether the main controller generates an activation command may be determined according to the state of the vehicle to reduce power consumption of the main controller. As shown in fig. 4, the method comprises the following steps:
s301, identifying and receiving a control instruction for opening a door body of the vehicle and/or receiving a control instruction for controlling the vehicle to release a locking state, and sending an activation instruction to a slave controller.
Specifically, when the door body of the vehicle is opened, it indicates that the ignition starting possibility exists in the vehicle, and therefore, in order to enable the vehicle to have enough time to prepare for starting, when a control instruction for opening the door body is received, an activation instruction is sent to the slave controller.
Further, when the vehicle is unlocked, it indicates that the vehicle is about to be ignited for startup, and therefore, in order to enable the vehicle to have sufficient time for startup preparation, when a control instruction to control the vehicle to be unlocked is received, an activation instruction is sent to the slave controller. For example, when the key of the vehicle is shifted from the LOCK position to the ACC position, indicating that the vehicle is released from the LOCK state, an activation command is sent to the slave controller.
It should be understood that the two conditions of the door body opening and the vehicle unlocking state of the vehicle may be combined or may be used separately, and may be determined according to the actual situation, and are not limited herein.
S302, recognizing that a control instruction for opening a door body of the vehicle is not received, and a control instruction for controlling the vehicle to release the locking state is not received, and forbidding sending of an activation instruction to the slave controller.
Specifically, when the door body of the vehicle is not opened and the vehicle is not unlocked, the situation that ignition starting of the vehicle does not exist is indicated, and therefore, in order to reduce the energy consumption of the whole vehicle, the activation instruction can be forbidden to be sent to the slave controller. That is, when it is recognized that a control command to open the door body of the vehicle is not received and a control command to control the vehicle to release the locked state is not received, the transmission of the activation command to the slave controller is prohibited.
And S202, intermittently or continuously sending a wake-up request message to the slave controller in the activated state.
Specifically, when the slave controller is in the activated state, the wake-up request message may be intermittently sent to the slave controller. When the activation instruction is sent intermittently, the wake-up request message can be sent simultaneously, that is, the time interval for sending the wake-up request message is the same as the time interval for sending the activation instruction. In addition, the time interval for sending the wake-up request message can be selected according to the actual situation.
In addition, the slave controller in the activated state may also be selected to send the wake-up message continuously, which may be determined according to the actual situation, and is not limited herein.
It should be understood that, in this embodiment, the time for the master controller to send the activation instruction and/or the wake-up request message may be controlled to intermittently wake up the slave controller, so as to reduce energy consumption of the entire vehicle. For example, when the activation instruction is continuously sent, the wake-up request message may be intermittently sent; when the activating instruction is sent intermittently, the awakening request message can be sent intermittently or continuously; the specific conditions may be determined according to actual conditions, and are not limited herein.
In some embodiments, when the number of the slave controllers is two or more, the activation instruction may be sent to the slave controllers intermittently or continuously, so that all the slave controllers are activated according to the types of the slave controllers. As shown in fig. 5, the method comprises the following steps:
s401, identifying the type of the slave controller.
Specifically, in the present embodiment, the types of slave controllers include a readable-type slave controller and a non-readable-type slave controller; after the readable slave controller receives the activation instruction, the readable slave controller can analyze the activation instruction, analyze activation information in the activation instruction and then perform self activation according to the activation information; and the non-readable slave controller can only receive the activation instruction but cannot parse the information in the activation instruction.
Before sending the activation instruction, the master controller can determine the readable slave controller and the unreadable slave controller according to the type of the prestored slave controller.
S402, detecting and determining that the type of the slave controller is the non-readable slave controller, intermittently or continuously sending an activation instruction to a readable slave controller corresponding to the non-readable slave controller to activate the readable slave controller, analyzing the activation instruction by the readable slave controller, and sending the analyzed activation instruction to the corresponding non-readable slave controller to activate the non-readable slave controller.
Specifically, when the type of the slave controller is detected to be a readable slave controller, the slave controller directly sends an activation instruction to the slave controller, and the slave controller can be in an activation state after receiving the activation instruction and analyzing the activation instruction. When the type of the slave controller is a non-readable slave controller, the slave controller directly sends an activation instruction to the slave controller, and the slave controller cannot be activated because the slave controller cannot analyze activation information in the activation instruction; at this time, in order to activate the non-readable slave controller, an activation instruction may be selectively sent to the readable slave controller corresponding to the non-readable slave controller, and then the readable slave controller interprets the activation instruction and sends the interpreted activation instruction to the non-readable slave controller, thereby activating the non-readable slave controller, that is, indirectly activating the non-readable slave controller.
That is, when the type of the slave controller is the non-readable slave controller, the slave controller intermittently or continuously sends an activation instruction to a readable slave controller corresponding to the non-readable slave controller to activate the readable slave controller, the readable slave controller parses the activation instruction, and the parsed activation instruction is sent to the non-readable slave controller to activate the non-readable slave controller.
In summary, in the control method for the vehicle provided in this embodiment, the master controller sends the wake-up request message to the slave controllers in advance before the vehicle is ignited and started, so as to wake up at least part of the slave controllers, and the awakened slave controllers can monitor the state of the vehicle in advance, so that the vehicle can have sufficient time to monitor the state of the entire vehicle before being started, and make a start preparation, thereby improving the start performance and safety of the vehicle.
FIG. 6 is a flow chart illustrating a control method of a vehicle according to an embodiment of the disclosure. As shown in fig. 6, the control method of the vehicle according to the present embodiment includes, on the slave controller side, the steps of:
s501, receiving a wake-up request message sent by the master controller from the slave controller under the condition that the vehicle door is unlocked or opened and the vehicle is not ignited.
Specifically, when the master controller does not detect the ignition signal of the vehicle, the slave controller may receive the wake-up request message sent by the master controller after intermittently or continuously sending the wake-up request message to the slave controller.
S502, the slave controller executes the awakening process according to the awakening request message so as to enter an awakening state.
Specifically, after the slave controller receives the awakening request message, the awakening process is executed according to the awakening request message, and then the slave controller enters an awakening state, so that the state of the vehicle is monitored, the vehicle can have sufficient time to monitor the state of the whole vehicle before being started, starting preparation is made, and starting performance and safety of the vehicle are improved.
In some embodiments, before receiving the wake-up request message sent by the master controller, the slave controller may enter an active state according to an activation instruction sent by the master controller, so as to prepare for wake-up. Specifically, the master controller may intermittently or continuously send an activation command when the ignition signal of the vehicle is not detected, and may enter an activation state upon receiving the activation command from the slave controller.
Further, in order to reduce energy consumption of the entire vehicle, when the slave controller does not receive the wake-up request message sent by the master controller and determines that the time length of entering the activation state reaches the preset time length, it indicates that the slave controller does not need to detect the state of the vehicle before ignition start of the vehicle, and at this time, the slave controller may enter the sleep state.
In some embodiments, when the number of slave controllers is two or more, the types of the slave controllers include a readable slave controller and a non-readable slave controller; after the readable slave controller receives the activation instruction, the readable slave controller can analyze the activation instruction, analyze activation information in the activation instruction and then perform self activation according to the activation information; and the non-readable slave controller can only receive the activation instruction but cannot parse the information in the activation instruction.
To enable the non-readable slave controller to be in an active state as well, the non-readable slave controller can be activated indirectly with the readable slave controller. Specifically, when at least one slave controller is a readable slave controller, it may receive an activation instruction transmitted by the master controller, then parse the activation instruction, and transmit the parsed activation instruction to a corresponding non-readable slave controller, thereby activating the non-readable slave controller.
In summary, in the control method for the vehicle provided in this embodiment, the slave controller can receive a wake-up request message that is sent to the slave controller in advance by the master controller before the ignition of the vehicle is started; and then, after receiving the awakening request message, executing the awakening process, and entering an awakening state to monitor the state of the vehicle, so that the vehicle can have sufficient time to monitor the state of the whole vehicle before starting, and the vehicle is ready to start, thereby improving the starting performance and safety of the vehicle.
FIG. 7 is a flowchart illustrating a control method of a vehicle according to an embodiment of the disclosure. As shown in fig. 7, the control method of a vehicle according to the present embodiment includes the steps of:
and S601, detecting an ignition signal of the vehicle by the main controller when the vehicle door is unlocked or opened. Specifically, see the description in step S101 above, which is not described herein again.
And S602, if the ignition signal is not detected, the master controller sends a wake-up request message to the slave controller. Specifically, see the description in step S102, which is not described herein again.
S603, the slave controller receives the awakening request message sent by the master controller, and executes an awakening process according to the awakening request message to enter an awakening state. For details, see the description of the above steps S501-S502, and are not described herein again.
According to the control method of the vehicle provided by the embodiment of the invention, the main controller sends the awakening request message to the slave controller in advance before the ignition start of the vehicle, and the slave controller receives the awakening request message sent by the main controller, executes the awakening process and enters the awakening state to monitor the state of the vehicle in advance, so that the vehicle can have sufficient time to monitor the state of the whole vehicle before the start and make a start preparation, and the start performance and the safety of the vehicle are improved.
For ease of understanding, the control method of the vehicle in the present embodiment is explained below. As shown in fig. 8, in the control method of the vehicle according to the embodiment, when the door is opened or the vehicle is unlocked, the master controller sends a pulse signal to activate the slave controller, and sends a wake-up request message to enable the slave controller to be in a wake-up state, where a duration of the pulse signal may be 3 s; after the vehicle is ignited and started, the master controller continuously sends a pulse signal and a wake-up request message, so that the slave controller is continuously in a wake-up state; therefore, the control method of the vehicle in the embodiment monitors the state of the vehicle before the ignition of the vehicle is started, so that the vehicle can have enough time to prepare for starting. In the conventional vehicle control method, before the vehicle is ignited and started, the controller in the vehicle does not monitor the state of the vehicle, and only after the vehicle is ignited and started, the controller in the vehicle monitors the state of the vehicle, that is, the vehicle in the conventional vehicle control method does not have enough time to monitor the state of the whole vehicle before being started, so that the vehicle is difficult to prepare for starting. And when the vehicle is flamed out, the master controller is forbidden to send an activation instruction to the slave controller, so that the slave controller enters a dormant state.
In order to implement the method of the above embodiment, the present invention also provides a main controller for a vehicle.
