Example Embodiment

[0029]Combinefigure 1 withfigure 2 In this embodiment, a control method suitable for use in new energy commercial vehicle driving mode switches, defines three driving modes: ECO mode, normal mode (Normal mode) and motion mode (SPORT mode) three driving modes The gear position controller SCU outputs a driving force torque coefficient MAP of the corresponding mode to the torque module; the torque module outputs a torque request signal to the combined meter (IC), the VCU collects the key (key switch) signal to identify the current ignition of the vehicle. State, the SCU transmits the driving mode request information to the VCU through the torque module inside the VCU, the VCU combines the current power battery SOC value transmitted by the BMS, and finally determines the current driving mode, and outputs it to the IC. In the state of charge, the VCU monitors the SOC value change in real time.

[0030]The VCU controls the switching process of three driving modes:

Abstract

The invention discloses a control method suitable for switching driving modes of a new energy commercial vehicle, relates to the technical field of new energy commercial vehicles, and solves the problems that fluctuation exists in the existing driving mode switching process, switching of the driving modes cannot be adaptively adjusted according to the condition that the current electric quantity of a power battery is insufficient, and energy saving and environment protection cannot be optimized. According to the method, an ECO mode, an NORMAL mode and an SPORT mode are defined; an SCU outputs a driving torque coefficient of a corresponding mode to a torque module; the torque module outputs a torque request signal to an IC, a VCU collects a KEY signal to recognize the current ignition state of a vehicle, the SCU sends driving mode request information to the torque module in the VCU through the CAN bus, and the VCU finally determines the current driving mode according to the current power battery SOC value sent by the BMS and outputs the current driving mode to the IC to be displayed. According to the control method, the corresponding driving modes are reasonably selected according to different driving road conditions, and the comfortable driving feeling is improved.

Description

technical field [0001] The invention relates to the technical field of new energy commercial vehicles, in particular to a control method suitable for switching driving modes of new energy commercial vehicles. Background technique [0002] In the existing driving mode switching control method, the torque output is not accurately filtered and smoothed, resulting in fluctuations in the current torque output during the driving mode switching process, and it cannot be adapted according to the current insufficient power of the power battery The switching of the driving mode cannot be adjusted permanently, which cannot bring the user a comfortable driving experience, and cannot maximize energy saving, environmental protection and the improvement of the mileage of the vehicle. Contents of the invention [0003] In order to solve the problems that there are fluctuations in the switching process of the existing driving modes, and the driving mode switching cannot be adaptively adjus...
