Abstract

The invention discloses an electric vehicle multifunctional voice integration instrument, a motor controller and an electric vehicle. A system comprises an instrument, a communication wire and the motor controller; the instrument exchanges data with the motor controller through the communication wire according to an agreed communication protocol; an instrument circuit board is configured with an mcu, a voice chip, a power amplifier circuit and a power supply circuit; multiple related voice data of the electric vehicle are stored in the voice chip of the instrument; the instrument can also detect or process several header signals; the several header signals are also transmitted to the motor controller through the communication wire; the motor controller can also transmit partial parametersand states to the instrument through the communication wire to play related voices on the instrument or display the parameters and the states on an instrument panel. Therefore, a traditional single electric vehicle instrument can integrate multiple originally independent voice electric appliance parts. Therefore, the number of the electric appliance parts is greatly reduced, the wiring harness ends are simplified, the reliability is improved, and the cost is saved.
