Embodiment Construction

[0013] 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.

[0014] In the actual production of electric vehicles, considering the cost problem, the signal wires used in the existing bus control system are two ordinary wires. Interference still exists, and the signal transmitted on the signal line is extremely susceptible to interference from external pulse signals, resulting in transmission data errors. Through some simulation experiments, it can be clearly seen that under the interference of external pulse signals, the original signal will have a phenomenon that the high level is pulled down and the low level is pulled up.

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 voltage conversion modules are added in an original bus control system, and the voltage conversion modules are connected between a control module and a bus and between a function module and the bus respectively so as to improve the amplitude value of original bus transmission signals. The original bus transmission signals are sent by a signal sending end, the amplitude value of the original bus transmission signals is improved to a value through one voltage conversion module, and then the original bus transmission signals are transmitted to the other voltage conversion module through the bus, the other voltage conversion module recovers the amplitude value of the signals to an original value and then sends the signals to a receiving end, and therefore the interference resistance of the bus control system of the electric vehicle is greatly improved, and normal use and maintenance of the electric vehicle are achieved.

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...
