The invention relates to a steering wheel torque determination method and device, computer equipment, a computer readable storage medium and a computer program product. The method comprises the steps of obtaining a vehicle body pitch angle and a real-time rotation angle, a real-time rotation angle rate and an expected rotation angle of a steering wheel, determining an expected rotation angle rate and basic torque of the steering wheel according to the real-time rotation angle, the real-time rotation angle rate and the expected rotation angle, predicting a torque compensation value of the steering wheel according to the vehicle body pitch angle, the expected rotation angle and the expected rotation angle rate, and outputting the torque compensation value. A target torque of the steering wheel is determined based on the torque compensation value and the base torque, the target torque being used to adjust the steering wheel to the desired angle. By means of the method, control parameters in different driving environments do not need to be calibrated repeatedly, the more accurate target torque of the steering wheel can be obtained, and more accurate steering control is achieved.
