Abstract

The invention discloses a self-balanced single-wheel electric vehicle, which relates to the technical field of vehicles. A mudguard (1) is arranged on the upper side of a wheel (4); a wheel hub motor (2) is arranged in the middle of a wheel (1); a motor shaft (3) is arranged in the central hole of the wheel hub motor (2); connecting pieces (5) are arranged at two ends of the motor shaft (3); the lower side of each connection piece (5) is connected with a pedal plate (6) through a connecting rod (7); a micro processing unit (10) is connected with a three-phase PWM (Pulse Width Modulation) driving signal driving unit (15); the three-phase PWM driving signal driving unit (15) is connected with a three-phase half-bridge inverter circuit (16); and the wheel hub motor (2) is connected with a motor Hall sensor (18) and a motor current sensor (19) respectively. The self-balanced single-wheel electric vehicle has the advantages of small size, light weight, convenience for carrying, capability of solving the problem of balance due to the adoption of a balance algorithm and an advanced sensor technology, simple structure, easiness for operating, safety, reliability and low cost.

Description

Technical field: [0001] The invention relates to the technical field of vehicles, in particular to a self-balancing single-wheel electric vehicle. Background technique: [0002] Traditional electric bicycles have the following two disadvantages: 1.
