The invention relates to a driver demand torque analysis method and device, a vehicle, equipment and a medium, and aims to realize torque self-adaptive adjustment when the resistance of the vehicle changes in different road environments, so that a driver can still obtain an expected driving effect under the condition of not changing the operation of an accelerator pedal. Compared with human intervention of a driver, the method is more suitable for the actual state of the vehicle, the vehicle runs more smoothly, and the driver can obtain good driving experience. The method comprises the steps that according to the current driving mode of a whole vehicle, the actual vehicle speed, the actual accelerator pedal opening degree and the actual brake pressure, the target acceleration representing the requirement of a driver is determined; determining an initial target torque according to the target acceleration and the actual vehicle speed; according to the current actual vehicle speed, the actual acceleration, the torque reaching boundary mark and the target acceleration of the whole vehicle, closed-loop control torque is determined; and according to the initial target torque, the closed-loop control torque and the current whole vehicle wheel end torque boundary range of the whole vehicle, the final target torque representing the demand of the driver is determined.
