Description

Technical Field

[0001] The present invention relates to the field of automobile technology, and in particular to a visual customized driving mode control method and system. Background Art

[0002] With the development of vehicle intelligent cockpits, the selection of vehicle power modes has gradually changed from physical switches to car screen control. The driver can use the selection buttons on the car screen to select a driving mode as the vehicle's current driving mode from pre-defined driving modes such as economy, sports, and energy saving.

[0003] In order to increase the diversity of drivers' choices, most manufacturers have also added the option of customized driving modes for drivers, but this customized driving mode is also a combination of several pre-given driving modes, which cannot achieve infinite control and cannot maximize driving mode customization.

[0004] In view of the above problems, the inventors of the present invention finally obtained the present invention after a long period of research and practice. Summary of the invention

[0005] In order to solve at least one aspect of the above technical problems, the present invention provides a visual customized driving mode control method and system, which realizes the stepless control of power parameters and maximizes the customization of driving modes.

[0006] The technical solution adopted by the present invention is:

[0007] On the one hand, a visual customized driving mode control method is provided, comprising the following steps:

[0008] Display the vehicle's power parameters on the vehicle screen in the form of a percentage adjustment bar;

[0009] The driver inputs a desired power parameter value by dragging the percentage adjustment bar on the vehicle screen;

[0010] The vehicle computer transmits the desired power parameter value to the MSG controller or VCU controller;

[0011] The MSG controller or the VCU controller controls and adjusts the vehicle power system according to the desired power parameter values.

[0012] Furthermore, the power parameters include independent parameters and associated parameters;

[0013] The driver can adjust the desired value of the independent parameter arbitrarily within the full range of the percentage adjustment bar;

[0014] Each of the associated parameters is associated with at least one independent parameter, and an associated relationship between the associated parameter and the corresponding associated independent parameter is preset, and the current adjustable range of the associated parameter is limited according to the associated relationship and the current value of the independent parameter.

[0015] Furthermore, the power parameters include one or more of a torque increase rate coefficient, a torque decrease rate coefficient, a maximum output torque, a maximum recovery torque, and a maximum output power.

[0016] Furthermore, the torque increase rate coefficient, the torque decrease rate coefficient, the maximum output torque, and the maximum recovery torque are independent parameters; the maximum output power is an associated parameter, which is associated with the maximum output torque.

[0017] Furthermore, a default power mode is preset in the vehicle computer, and after the vehicle is started, the current value of the percentage adjustment bar of the power parameter is displayed on the vehicle computer screen according to the default power mode;

[0018] The driver makes adjustments based on the current value of the percentage adjustment bar of the power parameter.

[0019] Furthermore, after the driver completes the adjustment of the percentage adjustment bar of the power parameter, the adjusted power parameter value can be set as the default power mode.

[0020] Furthermore, a plurality of power modes are preset in the vehicle computer, and the driver can selectively set one of the preset power modes as the default power mode.

[0021] Furthermore, the power parameters also include one or more of IGBT maximum power, IGBT current rise rate, motor commutation change rate, motor coasting minimum output torque, and throttle output torque.

[0022] On the other hand, a visual customized driving mode control system is provided. Based on the above-mentioned visual customized driving mode control method, the system includes a vehicle computer, a MSG controller or a VCU controller, and a power system;

[0023] The vehicle computer is used to obtain a desired power parameter value in response to the driver's operation;

[0024] The vehicle computer transmits the desired power parameter value to the MSG controller or VCU controller in the form of CAN signal;

[0025] After receiving the corresponding CAN signal, the MSG controller or VCU controller overwrites the original parameter value and performs the final power control with the overwritten parameter value.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] Without adding new switches and new controllers, the present invention: 1. Increases driving pleasure; 2. Maximizes vehicle endurance with the subjective participation of the driver; 3. Increases user stickiness. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to more clearly illustrate the specific implementation methods of the present invention or the technical solutions in the prior art, the drawings required for use in the specific implementation methods or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are some implementation methods of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0030] Figure 2 A schematic flow chart of a visual customized driving mode control method according to an embodiment of the present invention is shown. DETAILED DESCRIPTION

[0031] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0032] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion that may include other elements not expressly listed in addition to those listed.

[0033] like Figure 2 As shown, a visual customized driving mode control method provided by the present invention can be executed by a visual customized driving mode control system provided by an embodiment of the present invention. The visual customized driving mode control system can be implemented in software and / or hardware. The visual customized driving mode control method includes the following steps:

[0034] Step S101: Display the vehicle's power parameters on the vehicle screen in the form of a percentage adjustment bar. Figure 1 As shown, it can be understood that the adjustable range is determined according to the upper and lower limit data of each power parameter allowed by the vehicle parameters, and the range is divided into levels of 0 to 100 to form a progress bar to achieve stepless adjustment.

[0035] In some embodiments, a default power mode is preset in the vehicle computer. After the vehicle is started, the current value of the percentage adjustment bar of the power parameter is displayed on the vehicle computer screen according to the default power mode, that is, after the driver starts the vehicle, the percentage adjustment bar of each power parameter on the vehicle computer screen has an initial position, and the vehicle performs power control according to the power parameter corresponding to the initial position. The driver adjusts the power parameter based on the initial position, feels the vehicle condition after the adjustment, and thus finds the power parameter value he wants.

[0036] Step S102: The driver inputs a desired power parameter value by dragging the percentage adjustment bar on the vehicle computer screen.

[0037] In some embodiments, after the driver completes the adjustment of the percentage adjustment bar of the power parameter, the adjusted power parameter value can be set as the default power mode. That is, the next time the vehicle is started, the power parameter value set by the driver this time will be displayed on the vehicle screen, thereby achieving the adjustment memory function.

[0038] More preferably, the vehicle computer has multiple power modes preset, such as balance, energy saving, sports, strong recovery, recovery, no recovery, etc. The driver can selectively set one of them as the default power mode, and can also change the default power mode to other preset power modes at any time. After the driver completes the adjustment of the percentage adjustment bar of the power parameter, it can be stored as a new power mode. There can be multiple new power modes, and the driver can selectively set one of the new power modes as the default power mode.

[0039] In some embodiments, the power parameters include one or more of a torque increase rate coefficient, a torque decrease rate coefficient, a maximum output torque, a maximum recovery torque, and a maximum output power.

[0040] Among them, the torque rise rate coefficient, torque drop rate coefficient, maximum output torque, and maximum recovery torque are independent parameters, that is, the driver can drag and adjust the aforementioned parameters within the full range of the percentage adjustment bar, that is, the adjustment range is 0 to 100. The maximum output power is an associated parameter, which is associated with the maximum output torque, that is, the adjustment range of the maximum output power is affected by the maximum output torque. The preset association between the maximum output power and the maximum output torque limits the adjustable range of the maximum output power according to the current value of the maximum output torque and the association.

[0041] It can be understood that the power parameters can also include other parameters based on the above implementation, such as IGBT (motor control module) maximum power, IGBT current rise rate, motor commutation change rate, motor coasting minimum output torque, throttle output torque, etc.

[0042] Step S103: The vehicle computer transmits the desired power parameter value to the MSG controller (engine controller) or the VCU controller (vehicle controller).

[0043] Step S104: The MSG controller or the VCU controller controls and adjusts the power system according to the desired power parameter value.

[0044] In another embodiment, the present invention provides a visual custom driving mode control system. Based on the above-mentioned visual custom driving mode control method, the system includes a vehicle computer, an MSG controller or a VCU controller, and a power system. The vehicle computer responds to the driver's operation to obtain the desired power parameter value. When the driver drives the vehicle normally, the VCU controller or the MSG controller will receive the CAN signal transmitted from the vehicle computer controller, parse the CAN signal and pass different parameters to the torque control. When the VCU controller or the MSG controller is developing software, it is necessary to reserve upper-level input interfaces for each power parameter. These interfaces can receive the corresponding CAN signals, assign and overwrite the parameter values, and participate in the final power control.

[0045] It should be understood that although Figure 2 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 2 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.

[0046] The above are only preferred embodiments of the present invention, which are only illustrative and not restrictive. The structures and connection modes of the components in the present invention can be changed, and any equivalent transformations and improvements based on the technical solution of the present invention should not be excluded from the protection scope of the present invention.
