[0053] As introduced in the background technology, the mode switching of the engine refers to the operation of adjusting the engine working mode under different working conditions.

Common mode switching methods include buttons, knobs or settings and adjustments through the vehicle control system. For engine control, especially in the mode switching of the engine, the prior art selects the engine operating mode through buttons, configures no-load, medium load and heavy load, and is limited by physical buttons and the engine controller cannot communicate directly with the user end. The configurable modes are relatively few and cannot be applied to complex working conditions. That is, the existing scheme urgently needs a control method for engine mode switching. In order to solve the problem that the prior art selects the engine operating mode through buttons, configures no-load, medium load and heavy load, and is limited by physical buttons and the engine controller cannot communicate directly with the user end. The configurable modes are relatively few and cannot be applied to complex working conditions, the embodiments of the present application provide an engine control method, a client, an engine controller and an engine system.

[0054] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0055] In this embodiment, a method for controlling an engine is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0056] Figure 1 FIG. 1 is a flow chart of an engine control method provided according to an embodiment of the present application. Figure 1 As shown, the method is applied to a client of an engine system, the engine system further comprising a cloud, a remote terminal and an engine controller, the remote terminal respectively communicates with the cloud and the engine controller, and the cloud also communicates with the client, comprising the following steps:

[0057] Step S101, when it is determined that the engine is online, obtaining the current operating mode of the engine;

[0058] Specifically, the current operating mode of the engine is obtained, which can be used to determine whether to change the operating mode or keep the last operating mode as the current operating mode after the user selects the mode.

[0059] Step S102, receiving and responding to a first instruction, sending a user selection mode to the cloud, so that the engine controller controls the engine to change the current operating mode, wherein the user selection mode is an operating mode different from the current operating mode, the first instruction indicates that the user needs to switch the current operating mode of the engine, and the cloud sends the user selection mode to the engine controller via the remote terminal;

[0060] Specifically, the user configures the engine operating mode according to needs, avoiding the problem of inaccurate judgment caused by automatic identification and switching back and forth between multiple modes.

[0061] Step S103, upon receiving the configuration success information sent by the cloud, it is determined that the engine has successfully completed the switching of the operating mode.

[0062] By obtaining the current operating mode of the engine when it is determined that the engine is online; receiving and responding to the first instruction, sending the user selected mode to the cloud, so that the engine controller controls the engine to change the current operating mode; and determining that the engine has successfully completed the switching of the operating mode when the configuration success information sent by the cloud is received. A method for directly selecting the engine operating mode on the client to complete the mode switching is proposed. This solves the problem that the prior art selects the engine operating mode through buttons, configures no-load, medium-load and heavy-load, and has few configurable modes due to the limitation of physical buttons and the limitation that the engine controller cannot communicate directly with the user end, and cannot be applied to complex operating conditions.

[0063] Specifically, users have psychological expectations for autonomous mode switching, and they can receive information about successful configuration, which can avoid the impact of engine operating mode switching on driving to the greatest extent.

[0067] Specifically, through the linkage of the client, cloud, remote terminal and engine controller, the adjustment of the engine operating mode is realized, which is convenient for customers to select engine parameters, better adapt to the current operating conditions of the vehicle, and improve the engine economy or power. The cloud and remote terminal are used as relay devices to enable the client to communicate with the engine controller. By sending a request to retain the above-mentioned current operating mode, even if the user does not want to change the operating mode, the user can choose to let the engine run according to the last operating mode or to let the engine run according to the default operating mode.

[0069] Specifically, the engine controller comprehensively adjusts the accelerator pedal filter time, accelerator pedal characteristic curve, external characteristic curve, rail pressure setting value, injection advance angle and emission characteristics according to the mode selected by the user, which can meet the user's different needs for economy and power. By setting the corresponding mapping relationship, it can also be easily found quickly.

[0070] In one embodiment of the present application, the operating mode of the above-mentioned engine is one of the following: urban mode, provincial road mode, high-speed mode, mountain mode, on-site operation mode and reverse short mode.

[0071] Specifically, the client is used to display and configure the engine operating mode. The present application sets 6 engine operating modes on the client. Through the configuration of the client, the problem of difficulty in expanding physical buttons in the prior art is avoided, which facilitates the expansion and upgrading of functions.
