Example 1
Fig. 1 is a flowchart of a vehicle temperature sensor diagnosis method according to an embodiment of the present invention, which is applicable to the case of diagnosing a vehicle temperature sensor, and the method may be performed by a vehicle temperature sensor diagnosis apparatus, which may be implemented in the form of hardware and/or software, and which may be configured in a computer. As shown in fig. 1, the method includes:
s110, acquiring voltage information of a current vehicle specified temperature sensor, and generating an electrical fault diagnosis result according to the voltage information.
Wherein the temperature sensor is a sensor that converts a temperature variable into a transmissible standardized output signal. The vehicle temperature sensor is used for measuring the temperature of each position of the vehicle, the designated temperature sensor is a temperature sensor which a user wants to measure, and the user can designate the temperature sensor to be measured through the position of the temperature sensor or the identification information of the temperature sensor.
Specifically, fig. 2 provides a schematic diagram of a connection relationship of a temperature sensor of a whole vehicle, and fig. 2 includes a temperature sensor, a control unit, an On-Board Diagnostics (OBD) On-board automatic diagnostic system (end of line, EOL) device and a diagnostic apparatus, and an electrical signal of the temperature sensor transmits the electrical signal to the respective control units through a CAN line, a hard line and other connection modes. Each control unit converts the electric signals sent by the sensors into temperature signals for detecting and controlling each subsystem of the whole vehicle, and meanwhile, the control units also transmit the temperature signals to an OBD diagnosis interface of the whole vehicle. When the vehicle is off line, the EOL equipment can read all temperature signals on the vehicle through the OBD diagnosis interface; when the vehicle is detected and maintained after sale, the diagnosis instrument can also read all temperature signals on the vehicle through the OBD diagnosis interface.
Fig. 3 is a flowchart of a vehicle temperature sensor diagnosis method according to an embodiment of the present invention, and step S110 mainly includes steps S111 to S115 as follows:
s111, acquiring voltage information of a current vehicle specified temperature sensor.
S112, determining a sensor fault condition according to the voltage information, wherein the sensor fault condition comprises the existence of an electrical fault and the absence of the electrical fault.
Optionally, determining the sensor fault condition according to the voltage information includes: judging whether the voltage information is located in a preset voltage interval, if so, determining that the sensor fault condition is that no electrical fault exists; otherwise, determining that the sensor fault condition is an electrical fault.
Specifically, the fault condition of the sensor can be determined by acquiring the voltage information of the current specified temperature sensor of the vehicle, namely, when the voltage information is located in a preset voltage interval, the fault condition of the sensor is determined to be that no electrical fault exists, and when the voltage information is not located in the preset voltage interval, the fault condition of the sensor is determined to be that electrical fault exists.
In one embodiment, the diagnosis time can be after the whole vehicle is assembled and before the engine or the motor is started, and at the moment, the output temperature values of all the temperature sensors on the vehicle are similar because the influence of the whole vehicle heat source is avoided, so that the accuracy diagnosis condition of the temperature sensors is met. Take the case of performing the offline diagnosis of the temperature sensor a as an example. Before the diagnosis of the vehicle temperature sensor a is performed, the vehicle needs to be electrified, but the engine or the motor is not started, and a whole vehicle diagnosis interface is connected with the EOL device. The EOL device can read the voltage information of the sensor a to judge whether electrical faults such as open circuit, short circuit, open circuit to ground, short circuit to ground and the like exist.
In one embodiment, the diagnosis time may be more than 10 hours after the engine or the motor of the vehicle is turned off, at this time, the medium temperature measured by each temperature sensor on the vehicle has been cooled to the ambient temperature, and the output temperature values of each temperature sensor are similar, so as to meet the accuracy diagnosis condition of the temperature sensor. Taking the after-market detection and diagnosis of the temperature sensor a as an example. Before the diagnosis of the vehicle temperature sensor a is performed, the vehicle needs to be electrified, but an engine or an electric motor is not required to be started, and a whole vehicle diagnosis interface is connected with a diagnosis instrument. The voltage information of the sensor a can be read by a diagnostic instrument so as to judge whether electrical faults such as open circuit to a power supply, short circuit to the power supply, open circuit to the ground, short circuit to the ground and the like exist.
S113, judging whether the sensor fault diagnosis condition is that an electrical fault exists, if yes, executing S114, otherwise, executing S115.
S114, determining the electrical fault diagnosis result as diagnosis abnormality.
Optionally, after determining that the electrical fault diagnosis result is the diagnosis abnormality, the method further includes: acquiring fault adjustment information based on an electrical fault diagnosis result; and performing fault restoration according to the fault adjustment information.
Specifically, if an electrical fault exists, fault repair is needed, namely fault adjustment information is determined, fault repair can be performed based on the fault adjustment information, so that an electrical fault diagnosis result is normal, then the temperature of the sensor can be further obtained, and subsequent sensor accuracy diagnosis is performed.
S115, determining that the electrical fault diagnosis result is normal diagnosis.
And S120, when the electrical fault diagnosis result is that diagnosis is normal, acquiring temperature measurement values of all the temperature sensors, and generating sensor accuracy diagnosis results according to all the temperature measurement values.
Optionally, generating a sensor accuracy diagnosis result according to each temperature measurement value includes: determining a target temperature measured value corresponding to the designated temperature sensor, and determining an average value of the measured values of all other temperature sensors except the target temperature measured value; calculating a difference between the target temperature measurement value and the average value; judging whether the difference value is larger than a preset threshold value, if so, determining that the sensor accuracy diagnosis result is abnormal; otherwise, determining the sensor accuracy diagnosis result as normal diagnosis.
Specifically, the controller can read the values of all other temperature sensors except the designated temperature sensor on the vehicle through a diagnostic instrument or an EOL device, and then calculate the average value of the values, wherein the average value of the temperatures is close to the ambient temperature and can be used as a detection temperature reference. And then calculating a difference value between the target temperature measured value corresponding to the specified temperature sensor and the average value, if the difference value is within a specified range, indicating that the temperature output by the specified temperature sensor is consistent with the ambient temperature, and if the difference value is not within the specified range, indicating that the temperature output by the specified temperature sensor is greatly different from the ambient temperature, and the sensor accuracy is poor. The method and the device for diagnosing the precision of the temperature sensor of the whole vehicle create a precondition for diagnosing the precision of the temperature sensor of the whole vehicle by utilizing the characteristic that the output temperature values of the temperature sensors of the whole vehicle are similar before the vehicle is off line and after the vehicle is shut down for a long time, and the precision diagnosis is carried out by taking the average value of all the temperature sensors of the whole vehicle except the designated temperature sensor as a temperature reference and calculating the difference value between the output value of the designated temperature sensor and the temperature reference.
S130, determining a sensor diagnosis result according to the electrical fault diagnosis result and the sensor accuracy diagnosis result.
Specifically, before the diagnosis of sensor temperature diagnosis, the diagnosis of electrical faults of the sensor is performed, that is, the electrical faults are identified and eliminated by using the diagnosis equipment, and errors caused by faults such as open circuit, circuit breaking and the like are eliminated. And finally, the electrical fault diagnosis result and the sensor precision diagnosis result are combined to determine the sensor diagnosis result, namely, when the electrical fault diagnosis result is normal and the sensor precision diagnosis result is normal, the sensor diagnosis result is determined to be normal.
According to the technical scheme, the electrical fault diagnosis result is generated by acquiring the voltage information of the current specified temperature sensor of the vehicle, when the electrical fault diagnosis result is that diagnosis is normal, the sensor accuracy diagnosis is carried out, errors caused by the electrical fault can be eliminated, the sensor accuracy diagnosis result can be determined through each temperature measurement value, and further the sensor diagnosis result is determined, the applicability is wider, the diagnosis on the temperature sensor accuracy is realized, and the reliability of the whole vehicle is improved.
