Problems solved by technology

If the post-processing torque limit fault is not repaired for a long time, it will cause the engine to limit torque output after a period of time
At present, the vehicle can only display the remaining time of engine torque limit, but not the mileage before the engine torque limit. Some drivers are more intuitive to see the remaining time, and some drivers are more intuitive to see the cruising range, and only display the engine torque limit. In the remaining time, it is not convenient for the driver who is more intuitive to see the cruising range to make an accurate judgment on the engine torque limit
The processing methods for engine torque limit faults in the prior art cannot meet the different needs of different drivers

Embodiment 1

[0039] like figure 1 As shown, the present embodiment provides a method for processing engine torque limiting faults, including the following steps:

[0040] S10. Real-time monitoring of the mileage traveled by the vehicle within a set time.

[0041] Optionally, the set time is from 10h to 30h.

[0042] In this embodiment, the set time is 30h.

[0043] Optionally, the engine ECU stores the mileage per hour within the set time at the current moment, and accumulates the mileage within the set time according to the accumulation principle of first-in-first-out.

[0044]The engine ECU records the mileage of each hour of engine operation. The specific recording method is: first store the accumulated mileage A, and when the engine running time reaches 1 hour, record the accumulated mileage B, Tot1=B-A. Subsequently, the driving mileage of each hour is stored sequentially, and a total of 30 hours of driving mileage are stored. After 30 hours of mileage are stored in the engine ECU...

Embodiment 2

[0072] This embodiment provides a processing system for a limited engine torque fault, using the processing method for a limited engine torque fault provided in Embodiment 1, the processing system for a limited engine torque fault includes an engine ECU, a speed sensor and an interactive interface, a speed sensor, The interactive interface is electrically connected with the engine ECU, the speed sensor is used to collect the driving speed of the vehicle, and the interactive interface is used to display the real-time cruising range.

[0073] In this embodiment, the speed sensor sends the collected driving speed of the vehicle to the engine ECU, and the engine ECU stores the calculation formula for calculating the driving mileage within the set time, the calculation formula for the average driving mileage per hour, and the real-time cruising range. Calculate the formula and record the driving time of the vehicle and the remaining time of the engine torque limiter activation at th...

Abstract

The invention discloses a processing method and a processing system for a torque limiting fault of an engine, and relates to the technical field of engines. The processing method for the torque limiting fault of the engine comprises the steps of monitoring the driving mileage of a vehicle within set time in real time; calculating the real-time endurance mileage from engine torque limiting occurrence according to the driving mileage within the set time and the remaining time of engine torque limiting activation; and displaying the real-time endurance mileage through the interactive interface when the condition of sending the endurance mileage is met. According to the processing method for the torque limiting fault of the engine, calculation of the real-time endurance mileage can be achieved, a driver is reminded of the real-time endurance mileage of the torque limiting fault of the engine after the post-processing torque limiting fault occurs, different requirements of different drivers are met, and the use convenience of the driver is improved.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a processing method and a processing system for an engine torque limiting fault. Background technique [0002] At present, when the engine has an after-treatment failure such as excessive emission, the engine will enter the limited torque mode. [0003] Damage to components in the after-treatment system during vehicle operation will lead to torque-limiting faults in the after-treatment. After the post-processing torque limiting fault occurs, it is necessary to inform the driver in time to repair it as soon as possible. If the post-processing torque limit failure is not repaired for a long time, it will cause the engine to limit the torque output after a period of time. At present, the vehicle can only display the remaining time of engine torque limit, but not the mileage before the engine torque limit. Some drivers are more intuitive to see the remaining time, and some drivers ...
