Abstract

The invention relates to the technical field of double-drive electric vehicle, in particular to a walking control system, a control system and a double-drive electric vehicle. The walking control system comprises a control unit, a walking operation unit, a first walking motor and a second walking motor as well as a first detecting unit and a second detecting unit, wherein the walking operation unit is used for inputting a set walking value to the control unit; the first walking motor and the second walking motor are used as walking control objects; the first detecting unit is used for detecting the output amount of the first walking motor; the second detecting unit is used for detecting the output amount of the second walking motor; and the first walking motor and the first detecting unit form a closed loop together with the control unit; and the second walking motor and the second detecting unit also form a closed loop together with the control unit. According to the invention, the differential speed of the double-drive electric vehicle can be preferably controlled.

Description

technical field [0001] The invention relates to the technical field of dual-drive electric vehicles, in particular to a walking control system, a control system and a dual-drive electric vehicle. Background technique [0002] At present, electric vehicles still adopt traditional open-loop control in the system application of dual-drive DC motors. Since the open-loop control has defects such as low control precision, susceptibility to external interference, and inability to compensate once an error occurs in the output, it is not suitable for high-precision operating environments. When applied to industries with high safety standards such as electric vehicles, although the open-loop system can save the feedback system, its demand for high sensitivity of electrical components has led to an increase in the quality requirements of related components. Invisibly, it increases the manufacturing cost and has instability. At the same time, in the case of differential speed control,...
