Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0015] In the actual production of electric vehicles, considering the cost problem, the signal lines used in the original bus control system are two ordinary wires. In fact, other wires with anti-interference functions such as shielded wires are used. Interference still exists. The signal transmitted on the signal line is easily interfered by the external pulse signal, resulting in the transmission data error. Through some simulation experiments, it can be clearly seen that under the interference of the external pulse signal, the original signal will appear high level and be interrupted. Pull low, ...

Abstract

The invention belongs to the field of electrical equipment, and particularly relates to an electric vehicle and a bus control system thereof. According to the electric vehicle and the bus control system of the electric vehicle, two difference circuit modules are added in an original bus control system, located at the two ends of an original bus, and connected with a control module and a function module respectively to convert original transmission signals to difference signals for transmission, namely the difference signal transmission mode is used for effectively solving the problem that bus transmission signals are easily interfered by EMI and are disorderly controlled in the bus control system, the purpose of preventing interference is achieved, and the bus control system of the electric vehicle is safer and more reliable.

Description

technical field [0001] The invention belongs to the field of electric equipment, in particular to an electric vehicle and its bus control system. Background technique [0002] The control module of an electric vehicle generally needs to be connected to the motor, the speed control handle, the instrument module and other peripheral devices. Usually, these devices connected to the control module are distributed at both ends of the electric vehicle during the assembly process. In addition to the Hall signal line and the motor line, the existing electric vehicle control system also includes at least one brake control line, three three-speed control lines, one current indicator line, and one speed indicator line, and may include Other functional control lines, etc., the wiring is very complicated. In order to simplify the wiring during the assembly process of electric vehicles and reduce the waste of human resources caused by the complicated wiring of traditional electric vehicl...
