The invention discloses a vehicle energy recovery torque control method and device and electronic equipment, and the method comprises the following steps: obtaining a working condition parameter of a vehicle energy recovery state, and calculating the minimum time for a vehicle to quit energy recovery according to the working condition parameter; according to the working condition parameters and the minimum time for the vehicle to quit the energy recovery, calculating an initial vehicle speed for the vehicle to quit the energy recovery, and according to the initial vehicle speed, controlling the vehicle to enter a preset vehicle energy recovery quit state; when the preset vehicle quits the energy recovery state, a step length factor of recovered energy of the vehicle is calculated according to the working condition parameters; and calculating a vehicle recovery energy value according to the step length factor of the vehicle recovery energy, and controlling the vehicle braking torque according to the recovery energy value. Therefore, control over the vehicle braking torque is achieved by calculating the limit value of the recovered energy during vehicle braking, and the problem that when the motor energy quits recovery in the process that the vehicle is braked to the low speed, under-braking and over-braking are caused by torque fluctuation, and the stability of the whole vehicle is affected is solved.
