Embodiment Construction

[0025] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0026] Such as figure 1 Shown: 1 is charging mode, 2 is standby mode, 3 is standing slope mode, 4 is forward driving mode, 5 is reverse driving mode, 6 is zero torque mode, 7 is constant speed mode, 8 is braking mode.

[0027] In the multi-mode pure electric vehicle of this embodiment, its working modes include charging mode 1, standby mode 2, zero torque mode 6, forward driving mode 4, backward driving mode 5, braking mode 8, standing slope mode 3 and constant speed mode 7. The vehicle controller judges the required working mode of the vehicle and performs mode switching. The switching control of the working mode is attached figure 1 , including mutual switching between charging mode 1 and standby mode 2; forward driving mode 4 and charging mode 1, and standby mode 2, and zero torque mode 6, and reverse driving mode 5, and braking mode 8, and parking mode 3 1. Mu...

Abstract

The present invention provides a multi-mode pure electric vehicle and its mode control method. Multiple input signals of the vehicle are given in the form of state flags, and different state combinations correspond to corresponding working modes, including charging mode, standby mode, zero torque Mode, forward driving mode, reverse driving mode, braking mode, parking mode and constant speed mode, the vehicle controller judges the required working mode of the vehicle according to the combination information of the state flag bits, and controls the mode switching. The invention makes the operation of the pure electric vehicle more reliable and efficient, and makes the driving experience similar to that of the traditional vehicle and more comfortable.

Description

technical field [0001] The invention relates to an automobile control system, in particular to a control mode and a control method of a pure electric automobile. Background technique [0002] The increasing shortage of oil resources has made people pay more and more attention to the protection of the environment and the effective and rational use of energy. Therefore, pure electric vehicles with high efficiency, energy saving and environmental protection have become one of the development trends of the automobile industry. The pure electric drive system can achieve low energy consumption. consumption and the ideal "zero emission", which has advantages that internal combustion engine vehicles cannot match. [0003] People have been deeply impressed by the driving experience of traditional fuel vehicles, especially the various humanized designs of high-end vehicles that bring people a comfortable driving experience. However, the working mechanism of pure electric vehicles is c...
