Electric automobile energy recovery system control method and system and automobile

The invention discloses an electric automobile energy recovery system control method and system and an automobile. The method comprises the steps that the brake pedal depth of a brake pedal of the automobile and the accelerator pedal depth of an accelerator pedal are acquired in the operation process of the automobile in a brake pedal control mode; when the depth of the accelerator pedal is smaller than a preset acceleration depth threshold value, the depth of the brake pedal is compared with a first preset depth threshold value and a second preset depth threshold value; the first preset depth threshold value is smaller than the second preset depth threshold value; when the depth of the brake pedal is smaller than the first preset depth threshold value, an energy recovery system is kept in a non-starting state; when the depth of the brake pedal is larger than or equal to the first preset depth threshold value and smaller than the second preset depth threshold value, a brake system of the automobile is in a cl
