Based on the foregoing embodiment, in another embodiment of the present utility model, based on the vehicle 0 and the vehicle controller 1 in the foregoing embodiment, fig. 5 is a schematic flow chart of an implementation of a temperature determining method provided in the embodiment of the present utility model, and as shown in fig. 5, a method for determining a temperature of a chassis controller by using a vehicle may include the following steps:
step 101, under the condition that the chassis controller is in a working state, acquiring first temperature data based on a first temperature sensor in the chassis controller, and determining the temperature of the chassis controller in the working state according to the first temperature data.
In the embodiment of the utility model, when the vehicle acquires the temperature data of the chassis controller, the first temperature data can be acquired based on the first temperature sensor in the chassis controller under the condition that the chassis controller is in the working state, and the temperature of the chassis controller in the working state can be determined according to the first temperature data.
Further, in the embodiment of the present utility model, the first temperature data may include first time information and first temperature information; wherein the first temperature information corresponds to the first time information; for example, the first time information is time t1, and the corresponding first temperature information is 65 ℃.
In the embodiment of the present utility model, fig. 6 is a second schematic implementation flow chart of a temperature determining method provided in the embodiment of the present utility model, and as shown in fig. 6, the method for determining a temperature of a chassis controller of a vehicle may further include the following steps:
and 102, under the condition that the chassis controller is in a stop working state, acquiring second temperature data based on a second temperature sensor in the preset controller at regular time.
In the embodiment of the utility model, when the vehicle acquires the temperature data of the chassis controller, the second temperature data can be acquired at regular time based on the second temperature sensor in the preset controller under the condition that the chassis controller is in a stop working state.
It should be noted that, in the embodiment of the present utility model, the second temperature data is data acquired based on the second temperature sensor in the preset controller, and since the chassis controller and the preset controller are both located in the passenger compartment of the vehicle, the second temperature data is the temperature data in the passenger compartment collected at regular time.
Further, in an embodiment of the present utility model, the second temperature data may include second time information and second temperature information; wherein the second temperature information corresponds to the second time information; for example, the second time information is time t2, and the corresponding second temperature information is 45 ℃.
It should be noted that, in the embodiment of the present utility model, in the stopped working state, the chassis controller is classified into two situations that the temperature can reach the ambient temperature (i.e., the temperature in the passenger cabin) and that the temperature cannot reach the ambient temperature according to the time period from the stop of the working to the re-working; for example, the ambient temperature is 28 ℃, when the time after the vehicle is stopped is long, i.e. the time when the chassis controller stops working is long, the temperature can be reduced from 60 ℃ just at the beginning to 28 ℃, i.e. the ambient temperature can be reached; and the vehicle is assumed to be started again after being stopped briefly, namely, the chassis controller is changed into the working state again after being stopped briefly, and the temperature of the chassis controller only drops to 45 ℃ from 60 ℃ when the chassis controller is stopped immediately, and then the chassis controller begins to rise again, namely, the chassis controller cannot reach the environment temperature.
And 103, under the condition that the temperature of the chassis controller is not reduced to be the same as the ambient temperature, calculating according to the second temperature data, and determining the temperature of the chassis controller.
In the embodiment of the utility model, when the chassis controller is in the stop working state, after the second temperature data is acquired based on the second temperature sensor in the preset controller, the temperature of the chassis controller can be determined by performing calculation processing according to the second temperature data under the condition that the temperature of the chassis controller is not reduced to be the same as the ambient temperature.
It can be understood that, in the embodiment of the present utility model, based on two temperature change conditions determined according to the time period from the stop to the re-operation of the chassis controller in the stop state, the condition that the temperature of the chassis controller is not changed to be the same as the ambient temperature may be divided into two conditions: one is a case where the chassis controller is in a stopped state and the ambient temperature is not yet reached in the case where the ambient temperature is reached, and the other is a case where the chassis controller is in a stopped state and the ambient temperature is not reached.
Further, in the embodiment of the utility model, when the vehicle estimates the temperature of the chassis controller based on the second temperature data, the temperature of the chassis controller may be determined according to the temperature change rate and the second temperature information and the second time information in the second temperature data.
For example, in an embodiment of the present utility model, the temperature during which the chassis controller is out of operation may be calculated based on the following equation:
T t ＝T 0 -kt(t≤t e ) (1)
wherein T is t The temperature at T time after the chassis controller stops working is represented by T 0 Temperature information (second temperature information) corresponding to the time when the chassis controller is stopped (second time information), k represents the temperature change rate, t represents the time information, t e The x and n embodiments of the present utility model are not specifically limited, for example, x may be 1.5, and n may be 5.
It should be noted that, in the embodiment of the present utility model, the temperature change range for n consecutive times of temperature data does not exceed x degrees celsius, that is, the temperature change tends to be stable and approaches to the ambient temperature; the continuous n increases in temperature indicate that the ambient temperature increases, for example, in summer, the air conditioner is turned off after the vehicle is stopped, the ambient temperature (temperature in the passenger compartment) slowly increases, the temperature of the chassis controller decreases faster, and when the ambient temperature is higher than the temperature of the chassis controller, the temperature of the chassis controller slowly increases with the ambient temperature.
Further, in the embodiment of the present utility model, according to the change condition of the temperature, the temperature change rate may be divided into a first change rate and a second change rate, where the first change rate corresponds to a case where the chassis controller is in a stop working state and the ambient temperature is not reached yet under a case where the chassis controller is in a stop working state, and the second change rate corresponds to a case where the chassis controller is not able to reach the ambient temperature.
Further, in an embodiment of the present utility model, for the determination of the first rate of change, the determination may be made by the following formula:
T e ＝T 0 -k 1 t e (2)
wherein t is e Representing the moment corresponding to the condition that the temperature change range of temperature data collected by a preset controller is not more than x ℃ for n times or the temperature is increased for n times; t (T) e Then it represents t e Temperature information acquired by a preset controller corresponding to the moment; t (T) 0 Temperature information corresponding to the stop working time of the chassis controller is represented; k (k) 1 I.e. the first rate of change.
It will be appreciated that in the embodiments of the present utility model, the above-described T is used to form a composite material 0 、T e T e By taking the above formula (2), the first rate of change k can be determined 1 。
In the embodiment of the present utility model, after the first rate of change is determined, the temperature of the chassis controller before reaching the ambient temperature may be calculated based on the formula (2) and the second temperature data.
Further, in an embodiment of the present utility model, for the determination of the second rate of change, the determination may be made, for example, by the following formula:
T w ＝T 0 -k 2 t w (3)
wherein t is w Indicating the moment when the chassis controller resumes operation after stopping operation, T w Representing t w The chassis controller corresponding to the moment is based on the temperature information acquired by the first temperature sensor, T 0 Temperature information corresponding to the stop working time of the chassis controller is represented; k (k) 2 I.e. the second rate of change.
It will be appreciated that in the embodiments of the present utility model, the above-described T is used to form a composite material 0 、T w T w By taking the above formula (3), the second rate of change k can be determined 2 。
In the embodiment of the present utility model, after the second rate of change is determined, the temperature of the chassis controller during the stop operation period when the chassis controller cannot reach the ambient temperature may be calculated based on the above formula (3) and the second temperature data.
And 104, determining the temperature of the chassis controller according to the second temperature data when the temperature of the chassis controller is reduced to be the same as the ambient temperature.
In the embodiment of the utility model, when the temperature of the chassis controller is not reduced to be the same as the ambient temperature, the calculation processing is performed according to the second temperature data, and after the temperature of the chassis controller is determined, the temperature of the chassis controller can be determined according to the second temperature data when the temperature of the chassis controller is reduced to be the same as the ambient temperature.
It can be appreciated that in the embodiment of the present utility model, since the preset controller and the chassis controller are both disposed in the passenger compartment, and the ambient temperatures of the preset controller and the chassis controller are the same or similar, after the chassis controller stops operating, when the temperature of the chassis controller is reduced to be the same as the ambient temperature (i.e., the temperature in the passenger compartment), the temperature of the chassis controller may be determined directly according to the second temperature data obtained by the preset controller.
Further, in the embodiment of the present utility model, generally, the chassis controller will decrease the temperature after stopping working and gradually approach to the ambient temperature, so step 104 may be performed after step 103; however, the present novel embodiment may also perform step 104 directly after step 102, i.e. it does not exclude that the chassis controller is at the same temperature as the ambient temperature after stopping operation.
The utility model provides a temperature determining method, wherein a vehicle can acquire first temperature data based on a first temperature sensor in a chassis controller under the condition that the chassis controller is in a working state; under the condition that the chassis controller is in a stop working state, acquiring second temperature data based on a second temperature sensor in a preset controller at regular time; after the second temperature data is obtained, under the condition that the temperature of the chassis controller is not changed to be the same as the ambient temperature, calculating according to the second temperature data, and determining the temperature of the chassis controller; and determining the temperature of the chassis controller according to the second temperature data in the case that the temperature of the chassis controller is changed to be the same as the ambient temperature.

For example, based on the vehicle 0 and the vehicle controller 1 in the foregoing embodiments, in another embodiment of the present utility model, fig. 7 is a schematic diagram illustrating implementation of a temperature spectrum determining method provided in an embodiment of the present utility model, as shown in fig. 7, a first temperature sensor 111 is built in the chassis controller 11, and may collect temperature data in the passenger cabin 2 when the chassis controller 11 works, a second temperature sensor 121 is built in the preset controller 12, and the preset controller 12 has a periodic wake-up function after sleep, that is, the vehicle 0 still can periodically collect temperature data in the passenger cabin 2 after being in a sleep state, and the temperature data and the chassis controller 11 are all placed in the passenger cabin 2, and have the same or similar ambient temperature; the remote information processor 4 may collect temperature data of the chassis controller 11 and the preset controller 12 and upload the temperature data to the cloud server, where the remote information processor 4 is connected with the chassis controller 11 and the preset controller 12 through the controller lan bus 3, and the cloud server may store and process the data after receiving the temperature data to obtain a temperature spectrum.
Further, in the embodiment of the present utility model, the temperature of the chassis controller 11 may be divided into a temperature in an operating state and a temperature in a stopped operating state; when the chassis controller 11 is in a working state, the first temperature sensor 111 built in the chassis controller can be used for collecting temperature data of the chassis controller, and when the chassis controller 11 is in a stop working state, the chassis controller does not have a periodic wake-up function, so that the temperature data after the chassis controller is not able to be obtained, and the process needs the preset controller 12 with the periodic wake-up function after dormancy to collect the temperature data.
Further, in the embodiment of the present utility model, the chassis controller 11 has a larger initial temperature change rate after stopping working, a smaller change rate when approaching to the ambient temperature, the process time is generally shorter, and the influence of the limited error on the full life temperature spectrum is smaller and can be ignored; according to the time period from the stop of the operation to the re-operation, the temperature change is classified into two conditions, that is, the ambient temperature can be reached and the ambient temperature cannot be reached, and the temperature during which the chassis controller 11 is stopped can be estimated by the aforementioned formula (1).
Further, in the embodiment of the present utility model, after the chassis controller 11 finishes the cooling process and reaches the ambient temperature, the chassis controller 11 and the preset controller 12 having the function of periodically waking up after dormancy have the same ambient temperature, so the temperature of the chassis controller 11 can be determined by directly using the preset controller 12 to collect the ambient temperature.
In the embodiment of the present utility model, fig. 8 is a schematic diagram of a third implementation flow of the temperature determining method provided in the embodiment of the present utility model, as shown in fig. 8, when the chassis controller 11 is in a working state, the temperature data is collected and sent to the telematics processor 4 (step 201), then it is determined whether the chassis controller 11 stops working (step 202), if so, the temperature data is collected by using the preset controller 12 (step 203), for example, the preset controller 12 may record the temperature information at the time T0 when the chassis controller 11 just starts to stop working, and continuously start the functions of collecting, processing and storing the temperature data, if not, the step 201 is continuously executed; after step 203, it may be then determined whether the chassis controller 11 resumes operation (step 204), and if so, the preset controller 12 sends the collected temperature data to the telematics processor 4, and turns off the functions of collecting, processing, and storing the temperature data (step 205), and continues to collect the own temperature data by the chassis controller 11, i.e., performs step 201; if not, then step 203 is continued.
Therefore, in the embodiment of the utility model, the acquisition of the full-working-condition temperature of the chassis controller can be completed by coordinating the preset controller under the different dormancy states with the chassis controller on the premise of not increasing the hardware cost. The remote information processor can upload the temperature data to the cloud server, and the chassis controller temperature spectrum determined based on the large sample temperature data can be obtained through further processing of the cloud server. Based on the big data, the temperature spectrum determined by the temperature data of the big sample can more accurately depict the temperature load of the chassis controller, the design cost of the controller can be effectively reduced, and the product quality of the controller is improved.
The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present utility model should be included in the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
