Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without making any inventive effort are within the scope of the present invention.

The invention provides a method, a device, equipment and a medium for processing a fault of an extended range automobile, which aim to solve the problem of processing the fault of the extended range automobile.

The extended range electric motor is called series hybrid power, the vehicle is driven by the power of a generator, the output power of an engine is only used for pushing the generator to generate electricity, and the output power of the system is derived from the motor. The fault diagnosis refers to the operation flow of carrying out inspection and cause analysis on the fault by using a professional automobile diagnosis tool according to relevant standard specifications and determining the fault part. Fig. 1 is a schematic diagram of a fault diagnosis flow provided in an embodiment of the present invention, as shown in fig. 1, the fault diagnosis and the processing are performed by combining the hard wire information and the controller area network (Controller Area Network, CAN) information, and finally the CAN information is output. Fig. 2 is a schematic diagram of an extended-range electric vehicle fault handling system according to an embodiment of the present invention, as shown in fig. 2, all vehicle controller units 1 are connected to a vehicle controller 2 through a CAN network, and the vehicle controller 2 is connected to a fault handling unit 3. Wherein the vehicle controller unit 1 includes: the system comprises a motor controller, a gearbox controller, a battery management system, a direct current-direct current controller, an air pump controller, an oil pump controller, an air conditioner controller and a range extender controller; the fault handling unit 3 includes: the system comprises an instrument display module, a motor controller, a gearbox controller, a high-voltage relay and a battery management system. In the using process of the range-extended automobile, faults possibly occur, and the driving safety or driving experience of the automobile is affected. Therefore, the invention provides a method for processing the fault of the extended range automobile so as to ensure the driving safety as much as possible and improve the driving experience.

In order to better understand the aspects of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. The embodiment of the invention provides a method for processing a range-extended automobile fault, which is applied to a whole automobile controller. Fig. 3 is a flowchart of a method for handling extended-range automobile faults, which includes:

s10: acquiring a fault grade and a fault code sent by a controller with abnormal states;

s11: analyzing the fault code and acquiring corresponding fault information;

s12: detecting whether the controller with abnormal state is only a fault of the range-extending controller; if yes, go to step S13; if not, go to step S14;

s13: determining a corresponding fault processing strategy according to the fault grade and the fault information of the fault of the range-extending controller;

s14: determining a corresponding fault processing strategy according to the fault priority of the controller with abnormal state;

the other controllers are controllers except the program increasing controller in all the controllers of the program increasing automobile.

When each controller is produced, a manufacturer can prescribe the fault level of the controller, and after each controller is installed on the extended range automobile, the controller judges the fault level of the controller according to the fault level preset by the manufacturer, so that the fault level of the controller is determined. When a system fault occurs, the controller with the fault is in an abnormal state, and the controller with the abnormal state sends the fault grade and the fault code to the CAN bus, wherein the fault code is set according to a communication technology protocol, and the set fault code has fault information corresponding to the fault code.

And the whole vehicle controller processes the fault after receiving the fault information from the CAN bus. When fault processing is carried out, the fault grade of the whole vehicle can be judged according to the severity of the fault, and the corresponding fault code is stored and analyzed and then forwarded to the instrument so as to display and position the fault information. The vehicle controller divides the faults into three layers of fault grades, which are respectively: the system comprises a third fault level, a second fault level and a first fault level, wherein the third fault level is the most serious fault, the first fault level is the least slight fault, and a plurality of dimensions for measuring the severity of the fault are provided: the safety of vehicle-mounted personnel and driving is endangered, the output performance of a vehicle battery or a motor is related, the normal driving and the function of the whole vehicle are not influenced, and the vehicle can be recovered after power is turned off. The difference between the extended range electric vehicle and the pure electric vehicle is that the extended range power generation system is controlled, when the system only has a third-level fault in the extended range controller, the whole vehicle controller receives the fault level and then takes in the most serious fault of the whole vehicle for processing; when the system has other controller faults except the third-level faults of the range extender, the whole vehicle controller still receives the faults and then receives the most serious fault level of the whole vehicle to process, namely, the vehicle is controlled to stop. In practice, when the boost controller singly generates the third-level fault, the third-level fault may not affect the driving safety, and if the vehicle is directly controlled to stop running, the driving experience of the user may be affected. When the fault of the range-extending controller is concurrent with the fault of the other controller, specifically, when the fault of the third-stage fault which does not affect the driving safety is concurrent with the fault of the other controller, if the vehicle is directly controlled to stop running, the driving experience of a user is also affected. Therefore, in the embodiment of the invention, a corresponding fault processing method is provided for the case that the fault of the range-extending controller exists alone, and a corresponding fault processing strategy is provided when the fault of the range-extending controller exists in coexistence with other controllers.

And under the condition that the abnormal state controller is only a fault of the range-extending controller, determining a corresponding fault processing strategy according to the fault level and the fault information of the fault of the range-extending controller. When only the range-increasing controller fails, the corresponding failure processing strategy is not limited, and the corresponding failure processing strategy can be set according to the failure level of the range-increasing controller. Under the condition that the abnormal state controller is the coexistence of the extended range controller fault and other controller faults, determining a corresponding fault processing strategy according to the fault priority of the abnormal state controller; the other controllers are controllers except the program increasing controller in all the controllers of the program increasing automobile. The failure priority of the abnormal state controller is not limited, and is determined according to the type of the abnormal state controller and the failure level of the abnormal state controller.

The method for processing the extended range automobile fault is applied to a whole automobile controller, and comprises the following steps: acquiring a fault grade and a fault code sent by a controller with abnormal states; analyzing the fault code and acquiring corresponding fault information; under the condition that the controller with abnormal state is detected to be only a fault of the range-extending controller, determining a corresponding fault processing strategy according to the fault level and the fault information of the fault of the range-extending controller; under the condition that the controller with abnormal state is the coexistence of the fault of the extended range controller and the faults of other controllers, determining a corresponding fault processing strategy according to the fault priority of the controller with abnormal state; the other controllers are controllers except the program increasing controller in all the controllers of the program increasing automobile. Therefore, the corresponding fault processing strategy is determined according to the fault level and the fault information of the fault of the range-extending controller, so that the fault processing when only the single range-extending controller is in fault is realized, the corresponding fault processing strategy is determined according to the fault priority of the controller in abnormal state, the fault processing when the fault of the range-extending controller and the faults of other controllers coexist is realized, and the driving experience of a user is improved.

When the abnormal state controller is only a fault of the extended range controller, determining a corresponding fault processing strategy according to the fault level and the fault information of the fault of the extended range controller comprises the following steps:

and under the condition that the fault is detected to be the extended range controller only and is the first level fault or the second level fault, the indicator lamp on the control instrument displays a preset color to prompt the extended range controller to be faulty, wherein the severity of the first level fault is lower than that of the second level fault.

Because the first level fault and the second level fault of the range-extending controller do not affect driving safety, the range-extending controller is only prompted by the indication lamp display on the instrument in the embodiment. The preset color is not limited, and in general, a yellow lamp is turned on to prompt the fault of the increase control device, so that the vehicle can still drive normally.

Under the condition that the controller with abnormal state is detected to be the coexistence of the fault of the extended range controller and the faults of other controllers, determining the corresponding fault processing strategy according to the fault level and the fault information of the fault of the extended range controller comprises the following steps:

The fault treatment method comprises the following steps of:

removing the output torque of the driving end;

the fault processing method comprises the following steps of:

In this embodiment, the failure of the increase control is classified into a failure that affects the driving safety of the vehicle and a failure that does not affect the driving safety of the vehicle. The malfunction that affects or does not affect the driving safety of the vehicle is not limited. If the temperature of the engine is too high, the driving safety is not influenced, and if the temperature of the engine is too high, the false value of the engine torque is not influenced (the range-extending controller sends corresponding rotating speed torque to the engine according to the power requirement, then the engine feeds back the torque to the range-extending controller, and if the temperature of the engine and the range-extending controller are not equal, the false value of the engine torque is determined).

And for the three-level faults of the control unit of the increase control unit, which do not influence the driving safety of the vehicle, the three-level faults are directly processed according to the two-level faults of the whole vehicle. When the second-level fault processing is carried out according to the whole vehicle, the color of the indicator lamp displayed on the instrument is not limited, if the maximum vehicle speed of the limited vehicle is 40km/h, the yellow indicator lamp of the instrument prompts a driver, and the vehicle can continue to travel to a safety zone for fault checking and maintenance. For three-level faults affecting the driving safety of the vehicle, the driving end is firstly cleared to output torque, then the high-voltage relay is disconnected, and the whole vehicle is in a no-load state.

In the method provided by the embodiment, under the condition that only the increment controller faults exist, different fault processing strategies are provided for the three-level faults affecting the driving safety of the vehicle and the three-level faults not affecting the driving safety of the vehicle, so that the vehicle can still normally run when the three-level faults not affecting the driving safety of the vehicle occur, the driving experience of a user is improved, and when the three-level faults affecting the driving safety of the vehicle occur, the three-level faults of the whole vehicle are processed, and the driving safety is ensured.

The above describes a processing strategy when only the increase controller fault exists, and in this embodiment, a fault processing strategy when the increase controller fault and other controller faults coexist is provided. Specifically, determining a corresponding fault handling policy according to the fault priority of the controller with abnormal state includes:

under the condition that the fault of the step-up controller is detected to influence the driving safety of the vehicle, determining that the fault priority of the step-up controller is highest in all the controller faults with abnormal states, and determining a corresponding fault processing strategy according to the fault of the step-up controller;

and under the condition that the fault of the increase controller is detected to not influence the driving safety of the vehicle, determining a corresponding fault processing strategy according to the fault priorities of other controllers.

Further, determining a corresponding fault processing strategy according to the fault of the range-extending controller comprises:

The three-level fault handling strategy for the whole vehicle has been described above and will not be described in detail here.

The failure priority of the other controller is not limited, and in practice, the failure priority of the other controller is determined according to the type of the controller and the failure level of the controller.

When the other controllers are the oil pump controller and/or the air pump controller, determining the corresponding fault processing strategy according to the fault priority of the other controllers comprises the following steps:

determining that the fault priority of the increase control is lower than the fault priority of the oil pump controller and/or the air pump controller;

determining the fault handling policy as a corresponding fault handling policy of the oil pump controller and/or the air pump controller, wherein the corresponding fault handling policy of the oil pump controller and/or the air pump controller comprises at least controlling the vehicle to decelerate to a second vehicle speed;

when the other controllers are storage battery controllers, determining the corresponding fault processing strategies according to the fault priorities of the other controllers comprises:

determining that the fault priority of the boost controller is higher than the fault priority of the storage battery controller;

The second vehicle speed and the third vehicle speed are not limited. When the third-level fault and the oil pump and air pump second-level faults coexist in the range extender system, the whole vehicle controller combines the fault severity and the whole vehicle safety to carry out comprehensive treatment, the oil pump and the air pump relate to the whole vehicle steering and braking, certain potential safety hazards exist when the second-level faults occur, and the maximum speed of the vehicle is limited to be 30km/h. When the third-level fault and the second-level fault of the storage battery coexist in the range extender system, the storage battery is involved in the low-voltage electricity consumption requirement of the whole vehicle, and the maximum vehicle speed of the vehicle is limited to be 15km/h according to the existing storage battery capacity and the continuous electric energy capacity.

In the method provided by the embodiment, the driving energy of the range extender electric automobile is completely supplied by the range extender to the power system, so that longer endurance and a more convenient energy supply mode can be realized. Once the range-extending system has serious faults, the power generation is in an abnormal state, fault grade and fault information are reported to the CAN bus, the whole vehicle controller CAN identify the fault severity and type of different controllers after receiving the faults, and corresponding processing strategies are reasonably sent out, so that the vehicle CAN be guaranteed to continue running purely and continuously under the condition that the safety of the whole vehicle and personnel is not affected.
