The invention discloses a method and device for determining position information of a motor in a vehicle and the vehicle. Wherein a microprocessor, an excitation amplification circuit and a sine and cosine signal conditioning circuit are deployed in the vehicle, and the method comprises the steps that two excitation driving signals of the microprocessor are obtained, and the excitation driving signals are triggered by an excitation generation module in the microprocessor; based on the two excitation driving signals, determining two excitation differential amplification signals output by the excitation amplification circuit; based on the two excitation differential amplification signals, two sine and cosine differential signals are determined, and the sine and cosine differential signals are generated by a double-phase excitation double-phase output type rotary transformer in a motor of the vehicle; based on the two paths of sine and cosine differential signals, sine and cosine differential conditioning signal
