Detailed Description
The embodiment of the application provides a vehicle power type identification method, which is used for improving user experience.
Referring to fig. 1, an embodiment of a method for identifying a vehicle power type in an embodiment of the present application includes:
an on-board device is a device that extends for vehicle fault diagnostics (OBD) and is connectable to the vehicle OBD for obtaining vehicle data in communication with an Electronic Control Unit (ECU) of the vehicle. Wherein the vehicle-mounted device has data processing capabilities similar to the functionality of a vehicle OBD.
In this embodiment, the in-vehicle device sends a command to the vehicle based on the protocol to acquire the fuel type, the vehicle speed, or the engine speed of the detected vehicle, and the following vehicles are all detected vehicles.
101. The vehicle-mounted equipment acquires the fuel type of the vehicle.
After the vehicle-mounted equipment establishes communication connection with an ECU of a vehicle, the vehicle-mounted equipment sends a command for acquiring the fuel type to the vehicle based on a protocol, after the vehicle receives the command, the vehicle feeds back a response containing the vehicle fuel type information, the response and the fuel type have one-to-one correspondence, and the vehicle-mounted equipment acquires the fuel type of the vehicle based on the one-to-one correspondence. The communication connection may be a wired connection or a wireless connection, and is not limited herein.
102. And the vehicle-mounted equipment determines the power type of the vehicle according to the fuel category.
After the vehicle-mounted equipment acquires the fuel type, the vehicle-mounted equipment judges whether the fuel type meets a preset condition, and if the fuel type meets the preset condition, the vehicle-mounted system determines the power type corresponding to the fuel type based on the preset condition.
The preset condition is a one-to-one correspondence relationship set of fuel oil types and power types, and is set according to protocol contents. After the vehicle-mounted equipment obtains the specific fuel type, the vehicle-mounted equipment finds the corresponding relation which is adaptive to the fuel type from the relation set according to the obtained fuel type, and obtains the power type from the found corresponding relation, so that the vehicle-mounted equipment determines the power type of the vehicle.
In the case where the preset condition is not satisfied, the fuel type does not have a power type corresponding thereto. Specifically, when the vehicle-mounted device acquires the fuel type, the vehicle-mounted device cannot acquire the power type based on the acquired fuel type.
Therefore, it can be understood that the vehicle-mounted device may have an uncertainty about the type of power of the vehicle based on the acquired fuel classification. And for the condition that the power type cannot be determined through fuel analogy, namely the type of the fuel acquired by the vehicle-mounted equipment does not meet the preset condition, the vehicle-mounted equipment executes the following steps.
It should be noted that after the vehicle-mounted device determines the power type of the vehicle according to the fuel type, the vehicle-mounted device does not need to execute the subsequent steps; if the vehicle-mounted device does not determine the power type of the vehicle through the fuel type (i.e., the fuel type does not satisfy the preset condition), the subsequent steps are executed. It can therefore be seen that the preset conditions refer to the class of fuel that enables the determination of the type of vehicle power.
103. The vehicle-mounted equipment acquires the speed and the engine speed of the vehicle.
And if the fuel type of the vehicle acquired by the vehicle-mounted equipment does not meet the preset condition, the vehicle-mounted equipment acquires the speed and the engine speed of the vehicle within the preset time.
The vehicle-mounted equipment continuously sends two commands for obtaining the vehicle speed and the engine speed to the vehicle in a preset time period based on a protocol, the vehicle continuously receives the two commands in the preset time period and continuously feeds back a response containing the vehicle speed and a response containing the engine speed in the time period to the vehicle-mounted equipment, wherein the response containing the vehicle speed contains the vehicle speed, the response containing the engine speed contains the engine speed, and the vehicle-mounted equipment continuously receives the two types of responses in the time period and continuously obtains the vehicle speed and the engine speed from the response in the time period.
104. And the vehicle-mounted equipment determines the power type of the vehicle according to the vehicle speed and the engine speed.
After the vehicle-mounted device acquires all the vehicle speeds and the engine speeds within the preset time period, the vehicle-mounted device determines the power type based on all the vehicle speeds and the engine speeds acquired within the preset time period.
The vehicle-mounted equipment determines the power type of the vehicle according to all acquired vehicle speeds and the relationship between the engine speed and the power type. The mechanism of the relationship is that when the power type is a fuel type vehicle, the engine provides power when the power type is running, and the engine provides power, the running of the engine generates rotating speed, and the vehicle also generates vehicle speed, namely, when the power type is a fuel type vehicle, the vehicle speed is greater than zero when the power type is running, and the rotating speed of the engine is greater than zero; when the power type is a hybrid type vehicle, the power source is from two parts, the first part is powered by the motor, and the second part is powered by the engine. Wherein, both can not provide power simultaneously, can only select the energy supply, and also engine and motor provide power in switching over each other, can not the simultaneous operation. When the motor provides power, the vehicle only has the speed; when the engine provides power, the vehicle not only has the vehicle speed but also has the engine speed, namely, the power type is a hybrid vehicle, and when the vehicle runs, the vehicle speed is greater than zero, and the engine speed can be zero or greater than zero. Therefore, the vehicle-mounted device can determine the power type of the vehicle by the acquired vehicle speed and engine speed.
The preset time period is set by the vehicle-mounted device, and the power type of the vehicle can be accurately determined according to the acquired vehicle speed and the acquired engine speed, which is not limited herein.
It should be noted that, in the process of acquiring the vehicle speed and the engine speed by the vehicle-mounted device, the driving road condition of the relative motion of the vehicle does not affect the acquisition of the vehicle speed and the engine speed by the vehicle-mounted device.
It will be appreciated that the vehicle is in relative motion during the acquisition of the vehicle speed and the engine speed by the onboard equipment.
In this embodiment, the vehicle-mounted device determines the power type of the vehicle by acquiring the fuel type and the preset condition, and if the vehicle-mounted device cannot determine the power type of the vehicle by the fuel type, the vehicle-mounted device determines the power type of the vehicle by acquiring the vehicle speed and the engine speed within the preset time period of the vehicle. In addition, the vehicle-mounted equipment determines the power type of the vehicle through two modes, so that the complexity of determining the power type of the vehicle through a manual configuration mode in the prior art is avoided, and the user experience is improved.
Based on the embodiment of fig. 1, the following description is made for determining the power type of the vehicle by acquiring the fuel type, the vehicle speed and the engine speed of the detected vehicle through the ISO15765 protocol, and please refer to fig. 2, which includes:
in this embodiment, the vehicle-mounted device sends a standard OBD command to the vehicle based on an ISO15765 protocol to obtain the fuel type, the vehicle speed, or the engine speed of the detected vehicle, so as to determine the power type of the vehicle, that is, the detected vehicle.
201. The vehicle-mounted equipment acquires the fuel type of the vehicle based on an ISO15765 protocol.
After the communication connection between the vehicle-mounted equipment and the ECU of the vehicle is established, the vehicle-mounted equipment sends a standard OBD command for acquiring the fuel type to the vehicle based on an ISO15765 protocol, after the command is received by the detected vehicle, the detected vehicle feeds back a standard OBD response containing the fuel type information, and the vehicle-mounted equipment acquires the fuel type of the vehicle based on the standard OBD response containing the fuel type information.
The standard OBD command is a request command mode that is agreed by the vehicle-mounted device and the detected vehicle in advance based on the supported ISO15765 protocol, the standard OBD response is also an agreed response mode that is agreed by the vehicle-mounted device and the detected vehicle in advance based on the supported ISO15765 protocol, and the following step 203 is similar to this.
The standard OBD response containing the fuel type information has a one-to-one corresponding relation with the fuel type, so that the fuel type of the vehicle is obtained according to the one-to-one corresponding relation when the vehicle-mounted equipment receives the standard OBD response containing the fuel type information.
The communication connection established between the vehicle-mounted equipment and the ECU of the vehicle is specifically coupling between the vehicle-mounted equipment and the OBD of the vehicle, so that the vehicle-mounted equipment and the ECU of the vehicle are communicated with each other. It should be noted that the in-vehicle device has a connectable structure that matches the vehicle OBD, and the in-vehicle device establishes a connection with the vehicle OBD through the structure, thereby establishing a communication connection with the vehicle. For example, the connectable structure of the on-board device and the vehicle OBD may be an OBD connector, and the OBD connector is connected to the vehicle OBD interface, and similarly, the connectable structure of the on-board device and the vehicle OBD may also be an OBD interface, and the OBD interface is connected to the vehicle OBD connector, which is not limited herein.
202. And the vehicle-mounted equipment determines the power type of the vehicle according to the fuel category.
After the vehicle-mounted equipment acquires the fuel type, if the vehicle-mounted equipment can determine the corresponding power type based on the acquired fuel type, namely the fuel type meets a preset condition, the power type of the detected vehicle is determined; if the power type cannot be determined based on the acquired fuel type, that is, the fuel type does not meet the preset condition, the power type of the detected vehicle cannot be determined.
Specifically, when the vehicle-mounted equipment acquires the fuel type, the vehicle-mounted equipment determines the power type corresponding to the fuel type according to whether the acquired fuel type meets the corresponding relation of preset conditions, and if the vehicle-mounted equipment can find the power type based on the acquired fuel type, and the fuel type meets the preset conditions, the vehicle-mounted equipment determines the found power type as the power type of the detected vehicle; if the vehicle-mounted equipment cannot find the power type based on the acquired fuel type and the fuel type does not meet the preset condition, the vehicle-mounted equipment determines the power type of the vehicle through subsequent steps, wherein the corresponding relation between the fuel type and the power type is that when the fuel type acquired by the vehicle is more than or equal to 1 and less than 8, the power types corresponding to the range are all fuel types, and the condition is that the fuel type meets the preset condition; when the fuel type obtained by the vehicle is more than 8 and less than or equal to 22, the power types corresponding to the range are all hybrid power types, and the fuel type also meets the preset condition under the condition; when the fuel type obtained by the vehicle is 8, but the power type does not correspond to the fuel type when the fuel type is 8, the situation is that the fuel type does not meet the preset condition, and therefore the power type of the vehicle cannot be determined.
Based on the corresponding relation, the process that the vehicle-mounted equipment determines the power type through the fuel type is that when the fuel type acquired by the vehicle-mounted equipment is less than 8, the vehicle-mounted equipment determines that the power type of the vehicle is the fuel type; when the fuel type acquired by the vehicle-mounted equipment is more than 8 and less than or equal to 22, the vehicle-mounted equipment determines that the power type of the vehicle is a hybrid power type; when the fuel category acquired by the vehicle-mounted device is 8, the vehicle-mounted device cannot determine the power type of the vehicle, so that the fuel category of 8 can be regarded as a specific case that the preset condition is not met. Of course, the above numbers are merely exemplary, and other values may be used in practical applications, and the embodiments of the present application are not limited specifically.
It should be noted that after the vehicle-mounted device determines the power type of the vehicle according to the fuel type, the vehicle-mounted device does not need to execute the subsequent steps; if the vehicle-mounted device does not determine the power type of the vehicle through the fuel type (i.e., the fuel type does not satisfy the preset condition), the subsequent steps are executed. It can therefore be seen that the preset condition is whether the fuel class is a class from which the type of vehicle dynamics can be determined.
203. The vehicle-mounted equipment acquires the vehicle speed and the engine speed of the vehicle based on an ISO15765 protocol.
And if the fuel type of the vehicle acquired by the vehicle-mounted equipment does not meet the preset condition, the vehicle-mounted equipment acquires the speed and the engine speed of the vehicle within the preset time.
Specifically, the vehicle-mounted equipment continuously transmits a standard OBD command for acquiring the vehicle speed and a standard OBD command for acquiring the engine speed to the detected vehicle within a preset time period based on an ISO15765 protocol, correspondingly, the vehicle continuously receives the two commands within the preset time period and continuously responds a standard OBD response containing the vehicle speed and a standard OBD response containing the engine speed to the vehicle-mounted equipment, and the vehicle-mounted equipment continuously receives the standard OBD response containing the vehicle speed information and the standard OBD response containing the engine speed information and acquires the vehicle speed and the engine speed from the standard OBD response containing the vehicle speed information and the standard OBD response containing the engine speed information.
It can be understood that the vehicle-mounted device acquires a plurality of vehicle speeds and engine speeds within a preset time period.
204. And the vehicle-mounted equipment determines the power type of the vehicle according to the vehicle speed and the engine speed.
After the vehicle-mounted equipment acquires all the vehicle speeds and the engine rotating speeds within the preset time length, the vehicle-mounted equipment determines the power type based on the relationship between all the vehicle speeds and the engine rotating speeds acquired within the preset time length and the power type.
Specifically, if the vehicle speed acquired by the vehicle-mounted device in the preset time period is continuously greater than zero and the engine speed is greater than zero in the preset time period, namely, the condition that the engine speed is zero and the condition that the engine speed is greater than zero exist, the vehicle-mounted device determines that the power type of the vehicle is a hybrid power type; and if the vehicle speed acquired by the vehicle-mounted equipment in the period of time is continuously greater than zero and the engine speed is continuously greater than zero, the vehicle-mounted equipment determines that the power type of the vehicle is the fuel type. Because the power type of the detected vehicle is a fuel type vehicle, when the vehicle runs, the engine provides power, and when the engine provides power, the engine runs to generate a rotating speed, and the detected vehicle also generates a vehicle speed, when the vehicle speed obtained by the vehicle-mounted equipment within a preset time period is continuously greater than zero and the obtained rotating speed of the engine is also continuously greater than zero, the vehicle-mounted equipment determines that the power type of the detected vehicle is the fuel type; for the vehicle with the detected vehicle power type as the hybrid power type, the power source of the vehicle is from two parts, wherein the first part is powered by the motor, and the second part is powered by the engine. Wherein, both can not provide power simultaneously, can only select the energy supply, and also engine and motor provide power in switching over each other, can not the simultaneous operation. When the motor provides power, the detected vehicle only has the speed; when the engine provides power, the detected vehicle not only has the vehicle speed but also has the engine speed, so when the vehicle-mounted device acquires the vehicle speed continuously greater than zero within a preset time period and the acquired engine speed is zero and is also greater than zero, the vehicle-mounted device determines that the power type of the detected vehicle is the hybrid power type.
The preset time period is set by the vehicle-mounted device, and the power type of the vehicle can be accurately determined according to the acquired vehicle speed and the acquired engine speed, for example, the preset time period is within 5 minutes, and is not limited herein.
It should be noted that, in the process of acquiring the vehicle speed and the engine speed by the vehicle-mounted device, the driving road condition of the relative motion of the vehicle does not affect the acquisition of the vehicle speed and the engine speed by the vehicle-mounted device.
It will be appreciated that the vehicle is in relative motion during the acquisition of the vehicle speed and the engine speed by the onboard equipment.
In this embodiment, the vehicle-mounted device obtains the fuel type, the vehicle speed, and the engine speed of the vehicle based on ISO15765 to determine the power type of the vehicle, and also determines the power type of the vehicle in two ways, thereby avoiding the complexity of determining the power type of the vehicle in a manual configuration manner in the prior art, and improving user experience.
