[0019] To more clearly illustrate the technical solutions in the embodiments of the present invention and the prior art, the following will describe the specific embodiments of the present invention with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings, and other embodiments can also be obtained. In addition, the terms related to directions only represent the relative positional relationship between components, rather than the absolute positional relationship. Embodiment

[0020] An embodiment of the present invention provides a method for separating vehicle power. Please refer to Figure 1 , the vehicle power separation method includes: when a vehicle power separation instruction is detected, respond to the vehicle power separation instruction to separate the vehicle body from the battery.

[0021] Among them, the vehicle power separation instruction can be triggered and generated by the monitoring data of the vehicle state, or generated based on actual needs, such as actively performing a separation operation and separation demonstration during the maintenance of the vehicle power separation behavior; based on this, the vehicle power separation instruction can be formed based on signals from two different sources, namely, a passive separation decision signal and an active separation decision signal. Specifically: The passive separation decision signal is used to determine whether to trigger the vehicle power separation instruction according to the monitoring data of the vehicle state; the active separation decision signal is realized based on manual operation. For example, the staff operates the vehicle according to actual needs to achieve vehicle power separation.

[0022] In the embodiments of the present application, the active separation decision signal is implemented by manual decision-making. The applicable scenarios may include vehicle maintenance, repair, separation function maintenance, separation function display, etc.; however, when performing active separation, a third party should conduct a safety confirmation to ensure that the implementation of the separation function will not cause safety hazards.

[0023] Exemplarily, the vehicle power separation function can be integrated on the in-vehicle terminal, and the staff can send the active separation decision signal through the in-vehicle terminal to achieve vehicle power separation. To prevent accidental touch, separation decision verification can be configured, and the separation risk can be informed at the same time. Among them, the separation decision verification can be passed by the vehicle enterprise after confirmation. After passing the decision verification, the vehicle can execute the vehicle power separation instruction triggered by the active separation decision signal.

[0024] In the embodiments of the present application, the passive decision signal is based on the monitoring data of the vehicle state, and the monitoring data may include vehicle collision warning information and battery abnormality information. Among them, for the vehicle-battery separation instruction triggered based on vehicle collision warning information, when a vehicle is about to collide, the battery is separated. When the vehicle hits an obstacle, its kinetic energy becomes smaller, reducing the collision damage. At the same time, the risk of the battery catching fire during the collision is reduced. Even if the battery catches fire, it can also separate the ignition source, reduce the harm to the vehicle interior, classify and rescue, facilitate firefighting, improve the rescue efficiency, and reduce property losses.

[0025] For the vehicle-battery separation instruction triggered based on battery abnormal information, the on-fire battery can be separated in time, avoiding the whole vehicle catching fire and reducing property losses. At the same time, the fire range can be reduced, avoiding unnecessary losses to other personal or non-personal property around.

[0026] In the embodiments of the present application, the risk of the battery catching fire during a collision is relatively high, but it is generally closely related to the vehicle speed. Therefore, it is possible to judge whether vehicle-battery separation is needed based on the vehicle speed and conventional collision warnings. At low vehicle speeds, generally, the battery will not be impacted, so vehicle-battery separation is not required. While at high vehicle speeds, the risk of impacting the battery and causing it to catch fire is relatively high, and vehicle-battery separation can be carried out to reduce collision damage, improve safety, and at the same time, reduce property losses.

[0027] Based on this, the vehicle collision warning information can be based on the monitoring data of two aspects of the vehicle state. One is the vehicle speed, and the other is whether there is a collision warning.

[0028] The vehicle speed can be used as the activation threshold for vehicle-battery separation behavior. After the vehicle speed reaches a certain value and then a collision warning is detected, vehicle collision information is formed, and the vehicle-battery separation instruction is triggered by the vehicle collision information.

[0029] Exemplarily, triggering vehicle collision warning information specifically includes: Presetting the starting vehicle speed for passive separation decision; When and only when the vehicle speed reaches the starting vehicle speed, the vehicle-battery separation instruction triggered by the vehicle collision warning information is responded to.

[0030] Among them, the starting vehicle speed can be determined by actual measurement for each vehicle model to ensure that the vehicle collision intensity is within a safe range and reduce the risk of the battery catching fire during a collision below the starting vehicle speed.

[0031] During normal driving, after the vehicle speed reaches the starting vehicle speed, the vehicle-battery separation instruction triggered by the vehicle collision warning information is responded to. If the vehicle speed does not reach the starting vehicle speed, even if a collision warning occurs, the vehicle-battery separation instruction is not triggered.

[0032] When the vehicle reaches the starting speed and a collision warning is generated, both the driver and the vehicle will intervene. If the intervention is timely and a collision can be avoided, the triggered vehicle-battery separation instruction can be revoked and vehicle-battery separation will no longer be performed. If there is no intervention or the collision risk cannot be eliminated after intervention, the vehicle-battery separation instruction should be executed.

[0033] Furthermore, when there is intervention, the vehicle speed will decrease. If the vehicle speed has dropped below the starting speed before responding to the vehicle-battery separation instruction, the vehicle-battery separation instruction can be revoked and vehicle-battery separation will no longer be performed. If the vehicle speed has not dropped below the starting speed before responding to the vehicle-battery separation instruction, the vehicle-battery separation instruction can be maintained and the vehicle-battery separation instruction can be responded to, causing vehicle-battery separation.

[0034] In the embodiments of the present application, when the vehicle reaches the starting speed and responds to the vehicle separation instruction triggered by the vehicle collision information, it specifically includes: Obtain the current vehicle speed and set a response delay according to the current vehicle speed; When a collision warning signal is detected, pre-trigger the vehicle-battery separation instruction; In the state where there is the collision warning signal, calculate the collision time between the vehicle and the obstacle in real time; When the collision time between the vehicle and the obstacle drops to the response delay, respond to the pre-triggered vehicle-battery separation instruction; When the collision warning signal disappears, cancel the pre-triggered vehicle-battery separation instruction.

[0035] In the present application, the specific response time of the vehicle-battery separation instruction is before the collision. For example, 1 second before the collision, the battery is separated; the specific response time can be preset according to the current vehicle speed and respond in advance based on the estimated collision time. That is, after the vehicle-battery separation instruction is triggered, it is not immediately responded to and executed, but delayed. Responding a certain time before the collision can avoid excessive inertia after the battery is separated, causing greater safety hazards. At the same time, it can also minimize property losses and give sufficient intervention time.

[0036] Exemplarily, the delay response time can be preset based on the current vehicle speed, vehicle model, etc. The vehicle model is a fixed parameter, and the current vehicle speed is a variable. The corresponding response delay can be preset based on the variable; or a corresponding calculation formula can be designed based on the variable, and the response delay of the vehicle model at the current vehicle speed can be obtained through calculation.

[0037] In this application, when there is a collision warning signal, it indicates that there is a collision risk between the vehicle and an obstacle; when the collision warning signal disappears, it indicates that there is no collision risk between the vehicle and the obstacle; with manual intervention, the collision risk may disappear, that is, there will be no collision between the vehicle and the obstacle. At this time, even if the vehicle speed does not drop below the starting speed, there is no need to perform vehicle-battery separation, so the pre-triggered vehicle-battery separation command can be cancelled.

[0038] In this application, when the collision warning signal is initially generated, a pre-triggered vehicle-battery separation command is issued. However, before the collision, there is an intervention time. Correct manual intervention can largely eliminate the collision risk. Therefore, it is necessary to continuously monitor whether the collision warning signal exists. If it exists, it indicates that there is still a collision risk, and it is necessary to estimate the collision time to ensure that the pre-triggered vehicle-battery separation command responds in a timely manner; if the collision warning signal disappears during the subsequent intervention process, it indicates that there is no collision risk. At this time, the pre-triggered vehicle-battery separation command does not need to be responded to and can be directly cancelled and the response sequence can be revoked; however, data such as trigger records and intervention behaviors should be saved, and these data can be used to optimize the decision-making of the vehicle-battery separation method.

[0039] In this application, the vehicle collision warning information is a triggering method under the vehicle's dynamic behavior. In actual situations, even when there is no collision, during the use of the battery, there are also spontaneous thermal runaway phenomena, such as spontaneous combustion during vehicle driving and spontaneous combustion during charging. These are all caused by the abnormal conditions of the battery itself, rather than caused by a collision.

[0040] On this basis, the battery abnormal information can include static abnormal information and dynamic abnormal information. Among them, the static abnormal information is the abnormal information generated by the battery when the vehicle is in a stationary state, and the dynamic abnormal information is the abnormal information generated by the battery when the vehicle is in a moving state. The abnormal information at least includes the temperature abnormal information of the battery.

[0041] When the vehicle-battery separation command is triggered by the battery abnormal information, the dynamic abnormal information of the battery can trigger the vehicle-battery separation command in the same way as the vehicle collision warning information, but the temperature should be used as the triggering threshold, that is, when the temperature of the battery reaches the preset abnormal threshold, the vehicle-battery separation command is triggered to separate the vehicle body from the battery.

[0042] Since the static abnormal information of the battery is the abnormal situation of the battery when the vehicle is in a stationary state, when responding to the vehicle-battery separation command triggered by the static abnormal information, there should be a difference from the situation when the vehicle is in a moving state.

[0043] According to the actual situation, when the vehicle-battery separation instruction is executed in a stationary state, the vehicle can be separated from the battery, but the battery and the vehicle body are still in a close proximity state. In the event of a battery fire, there is still a significant safety hazard to the vehicle body, as it is extremely easy to ignite the vehicle body. Therefore, after the vehicle-battery separation instruction is executed in a stationary state, the distance between the vehicle body and the battery should also be increased to prevent the safety hazard caused by the abnormal state of the battery from affecting the vehicle body and reducing property losses.

[0044] In a specific embodiment, when responding to a vehicle-battery separation instruction triggered by static abnormal information, a short-distance driving-away instruction is synchronously triggered. The short-distance driving-away instruction is used to make the vehicle drive away from its original position after the vehicle body is separated from the battery.

[0045] Exemplarily, the short-distance driving-away instruction can be divided into multiple phased instructions and actions to ensure that after the vehicle-battery separation, the vehicle body can still drive a short distance away from its original position, maintaining a certain distance between the vehicle body and the battery.

[0046] Specifically, the short-distance driving-away instruction may include an electric energy relay instruction, a short-distance driving instruction, and an electric energy termination instruction. Among them, the electric energy relay instruction is used to activate the electric power relay device, which is used to connect the separated battery and the vehicle body to enable the separated battery to continue supplying electric energy to the vehicle body; the short-distance driving instruction is used to activate the vehicle's automatic driving system to make the vehicle drive away from its original position; the electric energy termination instruction is used to activate the electric power termination device, which is used to cut off the electric energy supply established by the electric power relay device to disconnect the vehicle body from the separated battery.

[0047] In a feasible embodiment, after the battery is separated from the vehicle body, the separated battery can supply electric energy to the vehicle body through an extended wire harness. The extended wire harness can be wound and stored to form a winding coil, and the rotation of the winding coil is controlled by the electric power relay device. When rotating, the extended wire harness is released. The electric power relay device can specifically be a small motor that drives the winding coil to rotate and release the extended wire harness.

[0048] The electric power relay device and the winding coil formed by winding the extended wire harness can be integrated on the battery and separated from the vehicle body together with the battery; the inner end of the extended wire harness is fixedly connected to the battery terminal post, and the outer end of the extended wire harness is connected to the vehicle body. When the extended wire harness is released, even if the vehicle body and the battery are separated, the battery can still supply electric energy to the vehicle body.

[0049] In a feasible embodiment, after the vehicle body has completed its departure, the extended wiring harness can be disconnected from the vehicle body. A power interruption device can be configured on the vehicle body to clamp the outer end of the extended wiring harness to ensure the docking and conduction between the extended wiring harness and the vehicle body. After the vehicle body has completed its departure, the outer end of the extended wiring harness can be released to completely disconnect the battery from the vehicle body. The power interruption device can specifically be an electronically controlled clamping structure. In its normal state, the clamping structure maintains the clamping state. Springs, torsion springs, etc. can be configured to provide conventional elastic forces to achieve normal clamping. When a short-distance departure instruction needs to be executed, the driving structure does positive work to cooperate to achieve driving and clamping, maintaining a stable clamping effect. After the departure is completed, the driving structure does reverse work to overcome the elastic force to achieve the separation of the extended wiring harness from the vehicle body. The driving structure can specifically be a telescopic motor, which is connected to a power arm of the clamping structure and can be used to cooperate with the clamping to achieve driving and clamping and overcome the elastic force to achieve the separation of the wiring harness.

[0050] It can be understood that during normal clamping, it is supported by the elastic force; during driving and clamping, it is jointly supported by the positive driving force of the driving structure and the elastic force, and the clamping force is greater than that during normal clamping to ensure that the wiring harness does not detach during the departure process.

[0051] It can be understood that the installation positions of the power relay device and the power interruption device can be interchanged. The winding coil formed by winding the power relay device and the extended wiring harness is configured on the vehicle body, and the power interruption device is configured on the battery.

[0052] In the embodiments of the present application, in response to the vehicle-battery separation instruction triggered by static abnormal information, it specifically includes: Presetting an abnormal threshold for the battery temperature when the vehicle is in a stationary state; When it is detected that the temperature of the battery of the stationary vehicle reaches the abnormal threshold, generating the static abnormal information, and triggering the vehicle-battery separation instruction and the short-distance departure instruction by the static abnormal information; When it is detected that the vehicle-battery separation instruction is triggered by the static abnormal information, obtaining the short-distance departure instruction; Sequentially responding to the power relay instruction, the vehicle-battery separation instruction, the short-distance driving instruction, and the power interruption instruction.

[0053] In the embodiments of the present application, statically, the abnormal threshold for the battery temperature can be different from the abnormal threshold during dynamic operation. Or different static thresholds and dynamic thresholds can be set according to the specific working conditions of the vehicle, such as the static threshold during charging (the vehicle is stationary and turned off), the static threshold during discharging (the vehicle is stationary but not turned off), the dynamic threshold during discharging (driving while discharging), the dynamic threshold during charging (hybrid or range-extended vehicles can charge the battery during operation), etc.

[0054] In this application, when it is detected that the battery temperature of a stationary vehicle reaches an abnormal threshold, a vehicle-battery separation instruction and a short-distance driving instruction can be synchronously triggered based on static abnormal information. However, when executing the two instructions, the power relay instruction, the vehicle-battery separation instruction, the short-distance driving instruction, and the power interruption instruction can be sequentially responded to.

[0055] Among them, by first responding to the power relay instruction, the connection effect between the extended wiring harness and the separation end can be stabilized. The separation end is the clamping end of the power interruption device, the other end of the wiring harness is the fixed end, and the connection effect of the fixed end is stable. It can also ensure that after the battery is separated, it still forms a power supply circuit with the vehicle body to achieve short-distance driving. When responding to the power relay instruction, the vehicle can be started first, and the main control system can cooperate to execute vehicle-battery separation.

[0056] Second, respond to the vehicle-battery separation instruction, separate the battery from the vehicle body. The extended wiring harness is already in a released state and can be freely elongated without affecting the separation of the battery from the vehicle body, and the battery can land smoothly.

[0057] Third, respond to the short-distance driving instruction. At this time, the battery has been separated from the vehicle body, but still maintains power supply. The vehicle body can drive away from its original position autonomously and a certain distance away from the battery, which can be determined based on the length of the extended wiring harness.

[0058] Fourth, respond to the power interruption instruction, cut off the connection between the extended wiring harness and the vehicle body, and avoid the combustion behavior of the battery being transmitted to the vehicle body through the extended wiring harness.

[0059] In the above process, a risk warning can be synchronously issued at the first time when responding to the vehicle-battery separation instruction, and sent to both the vehicle owner and the official background server at the same time, for warning the vehicle owner (such as warning the vehicle owner / emergency contact by phone, warning through the mobile APP), so that the vehicle owner / emergency contact can timely understand the situation and organize rescue.

[0060] In the embodiments of this application, when responding to the vehicle-battery separation instruction triggered by other information, a risk warning can be issued, and the corresponding alarm content can be sent according to the specific information triggering the vehicle-battery separation instruction to achieve the effect of risk warning. The risk warning information sent specifically includes: After detecting that the vehicle-battery separation instruction is responded to, generate the risk warning information and upload the risk warning information to the shared data platform; The risk warning information at least includes the specific information triggering the vehicle-battery separation instruction and the positioning information of the vehicle. Among them, the specific information is the triggering reason, such as abnormal battery temperature, collision warning information, etc., and the positioning information of the vehicle is conducive to quickly determining the risk location and facilitating rescue.

[0061] On this basis, specific contacts of the vehicle, such as the vehicle owner / emergency contact, can be obtained on the shared data platform, such as the cloud server of the official background, to convey the risk warning; the risk warning can also be directly sent from the vehicle to the vehicle owner, or sent through the mobile phone APP.

[0062] Based on the shared data platform, the vehicle's battery-electric separation situation, location, etc. can be notified to other vehicle owners on the same road section to reduce the risk of secondary accidents.

[0063] For the battery-electric separation instruction triggered by abnormal temperature, a risk warning message can be sent immediately when it is triggered for quick rescue and timely loss recovery; for the battery-electric separation instruction triggered by the vehicle collision warning message, a risk warning message can be sent when it responds to avoid misjudgment of risks.

When the processor executes the decision-making program, the method in Embodiment 1 is implemented.

[0065] Among them, the storage module is used to store data and the decision-making program; the battery temperature detection module is used to monitor the real-time temperature of the battery; the collision warning module is used to establish a communication connection with the collision warning system configured on the vehicle to monitor in real time whether there is a collision warning signal for the vehicle; the speed detection module is used to detect the vehicle speed in real time; the GPS positioning module is used to obtain the location information of the vehicle; the processor is used to execute the decision-making program to implement the method in Embodiment 1.
