Brake control method and device for two-wheel drive electric vehicle

The invention belongs to the technical field of electric vehicle braking, and particularly relates to a braking control method and device for a two-wheel drive electric vehicle. The brake control method comprises the following steps that a brake pedal position signal, the current vehicle speed V and the current battery charge state value SOC are obtained, and the brake pedal stroke Ba is calculated; judging whether the current vehicle speed V, the current battery state-of-charge value SOC and the brake pedal travel Ba meet a preset relational expression at the same time or not; if yes, the relation between the current vehicle speed V and a preset maximum vehicle speed threshold value Vhigh is judged, and one of two parallel brake control modes is selected for control according to the judgment result; and if not, correspondingly controlling the friction braking torque of the driving shaft and the non-driving shaft. According to the braking control method and device, when the vehicle speed is low, the electric
