The invention discloses a vehicle speed limiting control method and system based on acceleration and a vehicle. The vehicle speed limiting control method comprises the steps that S1, the corresponding relation between the vehicle acceleration and the vehicle speed intervening in a threshold during vehicle speed limiting is obtained; s2, determining a vehicle speed limit value, and monitoring the current acceleration and speed value of the vehicle in real time; s3, an intervention threshold vehicle speed corresponding to the current acceleration value is determined, and a first vehicle speed difference value between the vehicle speed limit value and the intervention threshold vehicle speed is obtained; s4, the first vehicle speed difference value is compared with the current vehicle speed value, and the current vehicle driving mode is determined; s5, if the vehicle enters the vehicle speed limiting mode, an acceleration target curve that the current intervention threshold vehicle speed slowly approaches the vehicle speed limiting value is obtained; and S6, based on the target vehicle speed in the acceleration target curve, carrying out following control of the target vehicle speed on the current actual vehicle speed of the vehicle. According to the technical scheme, the vehicle speed can be controlled to slowly approach but not exceed the maximum limit value, and the vehicle running stability is guaranteed while the speed limiting requirement is met.
