The invention discloses an anti-collision method and device for a vehicle, the vehicle and electronic equipment, and the method comprises the steps: obtaining a waveform outputted by an ultrasonic radar on the vehicle, and determining a corresponding speed limit grade of the vehicle based on the waveform; obtaining the distance from the vehicle to the obstacle under different speed limit levels; in response to the change of the speed limit level, correcting the distance from the vehicle to the obstacle to obtain a target distance from the vehicle to the obstacle; the motor torque of the vehicle is corrected according to the speed limit grade, the motor rotating speed and the target distance, and the final motor torque of the vehicle is determined. And the motor torque of the vehicle is corrected according to the real-time speed limit grade, the motor rotating speed and the target distance, and the vehicle speed is controlled based on the final motor torque of the vehicle, so that collision of the vehicle is prevented, the anti-collision cost of the vehicle is reduced, and the anti-collision accuracy and reliability of the vehicle are effectively improved.
