Light control circuit of electric two-wheeled vehicle

Abstract

The invention relates to the technical field of electric vehicle circuit control, and particularly relates to a light control circuit of an electric two-wheeled vehicle. The light control circuit comprises resistors R3, R7, R14 and R15, a second diode, a fourth triode and a PMOS transistor which form an MOS transistor driving circuit, wherein one end of the resistor R14 is connected with the Light_Control end, and the other end of the resistor R14 is connected with the anode of the second diode; the cathode of the second diode is connected with the base of the fourth triode; the emitter of thefourth triode is connected to one end of the resistor R15; the other end of the resistor R15 is connected to the anode of the second diode; the collector of the fourth triode is connected to one endof the resistor R7 and the G electrode of the PMOS transistor respectively; the other end of the resistor R7 is connected with one end of the resistor R3, the other end of the resistor R3 is connectedwith the S electrode of the PMOS transistor; the D electrode of the PMOS transistor is respectively connected with a first steering lamp and a second steering lamp; the first steering lamp and the second steering lamp are connected in parallel. According to the embodiment of the invention, the MOS transistor driving circuit is formed, and the PMOS transistor controls the light switches of the front and rear steering lamps of the electric two-wheeled vehicle according to high and low levels, so that the problems of abnormal flickering of light and the like caused by unstable contact due to aging of the switches are avoided.

Description

technical field [0001] The invention relates to the technical field of electric vehicle circuit control, in particular to an electric two-wheeled vehicle light control circuit. Background technique [0002] With the hot concept of urban smart travel, the two-wheeled electric vehicle market continues to develop, and the market size will reach 100 billion yuan. Major two-wheeled electric vehicle manufacturers have also launched high-end series models one after another. High-end series electric vehicles put forward higher requirements for the reliability and safety of various peripheral controls, as well as some rigid requirements of relevant EU regulations. [0003] At present, the light control circuit of electric two-wheeled vehicles is relatively simple, such as figure 1 As shown, only the front and rear turn signals are connected in parallel and controlled by mechanical switches. [0004] The disadvantage of the existing technology is that with the aging of the switch, i...
