[0056] Embodiment 1

[0057] Please refer to Figure 1 , Figure 1 An example flowchart of a vehicle coolant filling and exhaust method provided for the present embodiment is shown in FIG. 3. The vehicle coolant filling and exhaust method includes the following steps.

[0058] S101, obtaining a default strategy of a controller.

[0059] S102, after detecting that the vehicle is connected to direct current, waking up the controller to provide power for the vehicle cooling circuit by the controller.

[0060] In the present embodiment, the vehicle cooling circuit is a serial cooling circuit or an independent cooling circuit.

[0061] In the present embodiment, the serial cooling circuit at least includes a valve, a water pump, a driving system, an evaporative radiator, a battery system, a battery cooler, and a battery heater.

[0062] In the present embodiment, the independent cooling circuit at least includes a first circuit and a second circuit, the first circuit includes a first water pump, a driving system, and an evaporative radiator, and the second circuit includes a second water pump, a battery system, a battery cooler, and a battery heater.

[0063] S103, driving the vehicle cooling circuit by the controller to make the coolant in the vehicle cooling circuit flow to remove the bubbles in the circuit.

[0064] As an optional implementation, driving the vehicle cooling circuit by the controller includes:

[0065] When the vehicle cooling circuit is an independent cooling circuit, driving the water pump in the independent cooling circuit to rotate at the maximum speed by the controller.

[0066] S104, detecting whether the vehicle cooling circuit has a fault, if yes, ending the flow; if no, executing step S105.

[0067] S105, adjusting the control strategy of the controller to the normal use control strategy when detecting that the flag of the default strategy is rewritten.

[0068] For example, when the vehicle cooling circuit is an independent cooling circuit, the method can be implemented through the following steps.

[0069] (1) When a new part is shipped, the default strategy of the controller which controls the water pump strategy is to drive the water pump to run at the maximum speed after the controller is woken up;

[0070] (2) The whole vehicle is connected to 12V direct current, the controller which controls the water pump is woken up and provides power for the water pump;

[0071] (3) The water pump runs at the maximum speed under the control of the controller, so that the coolant in the cooling circuit flows and the air bubbles in the pipeline are flushed away;

[0072] (4) The water pump can also detect whether there is a fault during the high-speed operation, if there is a fault, a fault code is generated and recorded, so that the production line can find it in time;

[0073] (5) The production line can use a diagnostic device to rewrite the flag of the strategy at a suitable station; the after-sales repair shop can also rewrite the flag of the strategy through an after-sales diagnostic instrument;

[0074] (6) After the flag of the strategy is rewritten, the strategy of the controller which controls the water pump strategy will return to the normal use mode of the user, that is, the valve, water pump and other actuators are correctly driven according to the designed temperature control strategy.

[0075] Please refer to Figure 5 and Figure 6 , Figure 5 and Figure 6 respectively show a structural schematic diagram of an independent cooling circuit.

[0076] In this embodiment, the execution subject of the method can be a computer, a server and other computing devices, which are not limited in this embodiment.

[0077] In this embodiment, the execution subject of the method can also be a smart phone, a tablet computer and other smart devices, which are not limited in this embodiment.

[0078] As can be seen, the automotive coolant filling and bleed method described in this embodiment can drive all valves in the cooling circuit to adjust to appropriate positions after the main temperature control strategy controller is activated, and then drive the water pump to operate at maximum speed. This method can detect whether coolant has been added to the cooling circuit, thus preventing the water pump from running dry for extended periods and being damaged. Simultaneously, even when coolant has been added to the cooling circuit, this method can also, by switching valves and adjusting the water pump to maximum speed, circulate the coolant in each section of the cooling pipes, thereby removing air bubbles from the pipes. Finally, this method can automatically repeat the same strategy each time the main temperature control strategy controller is activated, until the strategy flag is rewritten, thus ensuring the automatic operation effect of the method.

[0079] Example 2

[0080] Please refer to Figure 2 , Figure 2 This embodiment provides a schematic flowchart of a method for adding and bleeding automotive coolant. The method includes:

[0081] S201. Obtain the controller's default policy.

[0082] S202. After detecting that the vehicle is connected to DC power, wake up the controller so that the controller can provide power to the vehicle cooling circuit.

[0083] In this embodiment, the vehicle cooling circuit is either a serial cooling circuit or an independent cooling circuit.

[0084] In this embodiment, the serial cooling circuit includes at least a valve, a water pump, a drive system, an evaporative radiator, a battery system, a battery cooler, and a battery heater.

[0085] In this embodiment, the independent cooling circuit includes at least a first circuit and a second circuit. The first circuit includes a first water pump, a drive system, and an evaporative radiator. The second circuit includes a second water pump, a battery system, a battery cooler, and a battery heater.

[0086] S203. When the vehicle cooling circuit is a serial cooling circuit, the controller adjusts all valves and water pumps in the serial cooling circuit to the preset first position.

[0087] S204. Drive the water pump in the serial cooling circuit to operate at maximum speed, and stop driving the water pump in the serial cooling circuit after a first preset time period.

[0088] S205. Adjust all valves and water pumps in the serial cooling circuit to the preset second position through the controller.

[0089] S206, driving the water pump in the serial cooling circuit to run at the maximum speed, and stopping driving the water pump in the serial cooling circuit after a second preset time period.

[0090] In the embodiment, the above process can make the coolant in the vehicle cooling circuit flow, thereby taking away the bubbles in the cooling circuit.

[0091] S207, detecting whether the vehicle cooling circuit has a fault, if yes, ending the process; if no, executing step S208.

[0092] S208, detecting whether the flag of the default strategy is rewritten, if yes, executing step S209; if no, ending the process.

[0093] As an optional implementation, the method further comprises:

[0094] rewriting the flag of the default strategy by the pre-connected diagnostic device;

[0095] detecting whether the flag of the default strategy is successfully rewritten;

[0096] if yes, adjusting the control strategy of the controller to the normal use control strategy.

[0097] S209, adjusting the control strategy of the controller to the normal use control strategy.

[0098] For example, when the vehicle cooling circuit is a serial cooling circuit, the method can be implemented by the following process.

[0099] (1) the controller controlling the temperature control strategy is provided with a default strategy that the controller drives all the valves in the cooling circuit to adjust to appropriate positions after being woken up, and then drives the water pump to run at the maximum speed when the controller is shipped.

[0100] (2) the vehicle is connected to 12V direct current, the controller controlling the temperature control strategy is woken up, and the controller provides power for the valves, the water pump and other executing components.

[0101] (3) all the valves and the water pump in the cooling circuit are driven by the temperature control controller to adjust to appropriate positions, and then the water pump is driven to run at the maximum speed, at this time, the cooling circuit pipeline in which the coolant can flow is marked as circuit C1.

[0102] (4) the controller controlling the temperature control strategy starts timing when driving the water pump to run at the maximum speed, and stops driving the water pump after accumulating timing T1.

[0103] (5) The main temperature control controller drives all the valves in the cooling circuit to rotate to another position again, and drives the water pump to run at the maximum speed. At this time, the cooling circuit where the cooling liquid can flow should cover the cooling circuit pipeline that the previous circuit C1 does not contain, marked as circuit C2.

[0104] (6) The main temperature control strategy controller starts timing when driving the water pump to run at the maximum speed, and stops driving the water pump after accumulating the timing T2.

[0105] (7) In the process of S3 and S5, the valves, water pumps and other actuators can also be detected for faults at the same time. If there is a fault, a fault code is generated and recorded, so that the production line can be found in time.

[0106] (8) The cycle S3-S6 steps are repeated until the strategy flag bit is rewritten to terminate. The production line can use a diagnostic device to rewrite the flag bit of the strategy; the after-sales maintenance shop can also rewrite the flag bit of the strategy through an after-sales diagnostic instrument.

[0107] (9) After the strategy flag bit is rewritten, the strategy of the main temperature control strategy controller will return to the normal use mode of the user, that is, the valves, water pumps and other actuators are correctly driven according to the designed temperature control strategy.

[0108] Please refer to Figure 7 , Figure 7 shows a schematic diagram of the structure of a serial cooling circuit.

[0109] Please refer to Figure 8 and Figure 9 , Figure 8 and Figure 9 respectively show an example schematic diagram of a draining circuit.

[0110] In this embodiment, the execution subject of the method can be a computer, a server, or other computing devices, which are not limited in this embodiment.

[0111] In this embodiment, the execution subject of the method can also be a smart phone, a tablet computer, or other smart devices, which are not limited in this embodiment.

[0112] It can be seen that the automobile coolant filling and exhaust method described in the embodiment can drive all valves in the cooling circuit to adjust to appropriate positions after the main temperature control strategy controller is woken up, and then drive the water pump to run at the maximum speed. It can be seen that the method can detect whether the cooling circuit is added with coolant, so as to avoid the damage caused by long-time dry running of the water pump. At the same time, the method can also make the coolant in each section of the cooling pipeline flow by switching the valves and adjusting the water pump to run at the maximum speed, so as to realize the effect of taking away the bubbles in the pipeline. Finally, the method can also automatically repeat the same strategy after the main temperature control strategy controller is woken up each time until the strategy flag bit is overwritten, so as to guarantee the automatic operation effect of the method.
