As shown in fig. 1, the temperature detection method includes:
S110, acquiring a first ambient temperature of the vehicle detected by a temperature sensor.
The temperature sensor is a sensor for detecting the ambient temperature on the vehicle, and the temperature value detected by the temperature sensor is the first ambient temperature.
S120, acquiring the running state of the temperature sensor.
When the temperature sensor is applied, the temperature sensor may be in a normal state or not, namely in an abnormal state, and the data detected by the temperature sensor is not credible at this time, so that the operation state of the temperature sensor is used for indicating whether the temperature sensor is in normal operation or not.
S130, acquiring meteorological data.
Wherein the meteorological data includes the temperature of the national atmosphere monitoring point. The temperature is a local climate characteristic, the change is slow, meanwhile, the regional difference is small, and the national temperature data map can be obtained by collecting data of all-national atmosphere monitoring points in a cloud server.
S140, acquiring current position information of the vehicle.
The current position information refers to information capable of reflecting the specific position of the vehicle at present. Preferably, the current position information includes longitude and latitude information of the current position. In one particular embodiment, GPS positioning may be utilized to obtain latitude and longitude information for the engine.
S150, determining a second environment temperature of the vehicle based on the current position information and the meteorological data.
Wherein, since the weather data includes temperature, the environmental temperature of the vehicle at the current position, namely, the second environmental temperature, can be obtained according to the current position information and the weather data. Specifically, the temperature information of the cloud server can be obtained by using the remote terminal of the vehicle, so that no new investment is added based on the existing facilities, and the cost is low.
S160, determining the environmental temperature of the vehicle based on the first environmental temperature, the second environmental temperature and the running state.
And integrating the first environmental temperature directly detected by the temperature sensor and the second environmental temperature obtained according to meteorological data through the running state of the temperature sensor to comprehensively determine the environmental temperature of the vehicle. The method and the device realize the determination of the ambient temperature based on a large amount of data, and can effectively improve the effectiveness of the data.
According to the scheme, the first environment temperature of the vehicle is detected by the temperature sensor, the running state of the temperature sensor is obtained, the weather data is obtained, the current position information of the vehicle is obtained, the second environment temperature of the vehicle is determined based on the current position information and the weather data, and finally the second environment temperature of the vehicle is determined based on the current position information and the weather data. Compared with the prior art that the temperature sensor is used for detecting the ambient temperature, the temperature data is not accurate enough when the temperature sensor fails. According to the scheme, the first environment temperature directly detected by the temperature sensor and the second environment temperature obtained according to the meteorological data can be fused to comprehensively determine the environment temperature of the vehicle, the effectiveness of the environment temperature data is improved, and the problem that the temperature data is not accurate enough is solved.
Example two
Fig. 2 is a flowchart of a temperature detection method according to a second embodiment of the present invention, where the relationship between the second embodiment and the above embodiment is a modification of the first embodiment, and optionally, the determining the environmental temperature of the vehicle based on the first environmental temperature, the second environmental temperature and the running state includes: determining whether the operating state is a normal state; and if the running state is not the normal state, determining the environmental temperature of the vehicle based on the second environmental temperature. Optionally, after determining whether the operation state is a normal state, the method further includes: and if the running state is a normal state, determining the environmental temperature of the vehicle based on the relation between the difference value of the first environmental temperature and the second environmental temperature and a preset temperature deviation threshold value. Based on this, as shown in fig. 2, the temperature detection method includes:
s210, acquiring a first ambient temperature of the vehicle detected by a temperature sensor.
S220, acquiring the running state of the temperature sensor.
S230, acquiring meteorological data.
S240, acquiring current position information of the vehicle.
S250, determining a second environment temperature of the vehicle based on the current position information and the meteorological data.
S260, determining whether the running state is a normal state.
The method for determining the operation state of the temperature sensor is various, in the related art, the fault state of the temperature sensor can be determined through circuit fault detection modes such as open circuit detection and short circuit detection, when the temperature sensor has faults, the temperature sensor is determined to be not in a normal state, and when the temperature sensor does not have faults, the temperature sensor is determined to be in a normal state. In other embodiments, other methods of the related art may be used to determine the operating state of the temperature sensor, which is not particularly limited herein.
If the operation state is not the normal state, step S270 is executed. If the operation state is a normal state, step S280 is performed.
S270, determining the environmental temperature of the vehicle based on the second environmental temperature.
When the running state of the temperature sensor is not in a normal state, which indicates that the temperature sensor fails due to failure, the first environment temperature is unreliable, and the second environment temperature is used for determining the environment temperature of the vehicle due to degradation.
S280, determining the ambient temperature of the vehicle based on the relation between the difference value of the first ambient temperature and the second ambient temperature and a preset temperature deviation threshold value.
When the operation state of the temperature sensor is a normal state, the temperature sensor is not failed, but the temperature sensor may still be affected by a nearby heat source, and the measured value drift problem occurs. The preset temperature deviation threshold value refers to a threshold value which is not exceeded by the difference value between the first environment temperature and the second environment temperature when the measured value of the temperature sensor does not drift. By determining the ambient temperature of the vehicle not only from the first ambient temperature but also based on a relationship between a difference between the first ambient temperature and the second ambient temperature and a preset temperature deviation threshold, the accuracy of the ambient temperature is improved.
According to the scheme, the second environment temperature is used for determining the environment temperature of the vehicle in a degradation mode when the running state of the temperature sensor is not the normal state, and the environment temperature of the vehicle is determined based on the relation between the difference value of the first environment temperature and the second environment temperature and the preset temperature deviation threshold value when the running state of the temperature sensor is the normal state, so that the environment temperature can be accurately determined according to the state of the temperature sensor, the accuracy of the environment temperature is improved, and the problem that the engine control performance is abnormal due to the fact that the temperature of other sensors is inaccurate is effectively solved.
In an alternative embodiment of the present invention, the determining the ambient temperature of the vehicle based on the relationship between the difference between the first ambient temperature and the second ambient temperature and a preset temperature deviation threshold value includes:
Determining whether a difference between the first ambient temperature and the second ambient temperature is greater than a preset temperature deviation threshold.
If so, determining the ambient temperature of the vehicle based on the second ambient temperature.
If not, determining the ambient temperature of the vehicle based on the first ambient temperature.
When the measured value of the temperature sensor does not drift, the difference value between the first ambient temperature and the second ambient temperature does not exceed the threshold value, so that when the difference value between the first ambient temperature and the second ambient temperature is larger than the preset temperature deviation threshold value, the measured value of the temperature sensor drifts, and the difference between the first ambient temperature and the actual ambient temperature is too large, so that the ambient temperature of the vehicle is determined based on the second ambient temperature, and the accuracy of the ambient temperature is improved. When the difference between the first ambient temperature and the second ambient temperature is not greater than the preset temperature deviation threshold, the difference between the first ambient temperature and the actual ambient temperature is not great, and the numerical value of the temperature sensor is relatively real, so that the ambient temperature of the vehicle can be directly determined based on the first ambient temperature.
Example III
Fig. 3 is a flowchart of a temperature detection method according to a third embodiment of the present invention, where the relationship between the third embodiment and the above embodiment is a modification of the first embodiment, and optionally, the determining, based on the current location information and the weather data, a second ambient temperature of the vehicle includes: smoothing the current position information and the meteorological data; and determining a second ambient temperature of the vehicle based on the smoothed current position information and the meteorological data. Optionally, before determining the environmental temperature of the vehicle based on the first environmental temperature, the second environmental temperature, and the operating state, the method further includes: acquiring altitude information of the vehicle; correcting the second ambient temperature based on the altitude information; accordingly, the determining the ambient temperature of the vehicle based on the first ambient temperature, the second ambient temperature, and the operating state includes: an ambient temperature of the vehicle is determined based on the first ambient temperature, the operating state, and the corrected second ambient temperature. Based on this, as shown in fig. 3, the temperature detection method includes:
S310, acquiring a first ambient temperature of the vehicle detected by a temperature sensor.
S320, acquiring the running state of the temperature sensor.
S330, acquiring meteorological data.
S340, acquiring current position information of the vehicle.
S350, determining a second environment temperature of the vehicle based on the current position information and the meteorological data.
S360, smoothing the current position information and the meteorological data.
The current position information and the meteorological data are subjected to smoothing processing, so that acquisition noise can be effectively eliminated. Preferably, the smoothing treatment can be performed by Gaussian smoothing.
And S370, determining a second environment temperature of the vehicle based on the smoothed current position information and the meteorological data.
The current position information and the meteorological data after the smoothing effectively eliminate the acquisition noise, so that the obtained second environment temperature is accurate.
S380, acquiring altitude information of the vehicle.
The altitude refers to the vertical distance of a certain place on the ground above the sea level, and the altitude information is the altitude where the vehicle is located. In one particular embodiment, GPS positioning may be utilized to obtain altitude information for the vehicle.
S390, correcting the second ambient temperature based on the altitude information.
The influence of the altitude on the temperature is mainly reflected in that the air temperature is generally reduced along with the elevation, so that the accuracy of the second environment temperature can be higher by correcting the second environment temperature through the altitude information.
S3100, determining an ambient temperature of the vehicle based on the first ambient temperature, the operating state, and the corrected second ambient temperature.
Wherein, since the second ambient temperature is obtained by smoothing the current position information and the meteorological data while the second ambient temperature is subjected to altitude correction, the second ambient temperature accuracy is higher, and the ambient temperature accuracy of the vehicle is higher as determined based on the first ambient temperature, the running state, and the corrected second ambient temperature.
Optionally, smoothing the current location information and the weather data and correcting the second ambient temperature by altitude information may be performed separately in a specific order or simultaneously, which is not limited herein, and a specific method for performing smoothing and altitude correction is described in the following by a specific embodiment:
Firstly, dividing grids, dividing a map into equidistant grids, considering the temperature in each grid to be the same, and since the meteorological data are temperature data comprising atmosphere monitoring points, the temperature of part of the grids is known, namely, the known temperature points exist in the grids. As shown in fig. 4, points a and B are known temperature points, a, B, c, d are unknown temperature data, and the second ambient temperature at point a is:
Wherein: t A is the temperature of point A, D Aa is the horizontal distance between the points a and A, D AB is the horizontal distance between the points B and A, H Aa is the vertical drop of the points a and A, and the vertical drop can be obtained through altitude information, and T a can be obtained through the formula, namely the second environment temperature of point a is obtained.
Based on the same algorithm, the temperature values of the points A, a, B, c, d and B are obtained, and the smoothed values of the points can be obtained by adopting a Gaussian one-dimensional algorithm.
