The invention relates to a vehicle speed control method and system and a vehicle, and the method comprises the steps: determining a pre-driving road of the vehicle and obtaining the limiting speed of the pre-driving road in response to starting a switch for limiting the maximum vehicle speed of the vehicle; acquiring the current driving speed and acceleration of the vehicle; when the distance between the vehicle and the entrance of the pre-driving road is smaller than or equal to a preset distance threshold value, whether the vehicle keeps driving in a full-speed driving state or not is judged; if the vehicle runs in the full-speed running state, the accelerated speed is adjusted according to the preset adjustment amplitude, and the running speed is controlled to be adjusted to the limiting speed in the preset adjustment duration; and if the vehicle does not run in the full-speed running state, the acceleration is not adjusted. According to the vehicle speed control method and system and the vehicle, when the vehicle keeps running in the full-speed running state, the accelerated speed is adjusted so as to control the running speed to be adjusted to the limiting speed in the preset adjusting duration, and safety accidents caused by overspeed are avoided.

本申请涉及一种车辆速度控制方法、系统及车辆，方法包括：响应于开启车辆最高车速限制的开关，确定车辆的预行驶道路并获取预行驶道路的限制速度；获取车辆当前的行驶速度和加速度；当车辆与预行驶道路的入口之间的距离小于或等于预设的距离阈值时，判断车辆是否保持全速行驶状态行驶；若车辆保持全速行驶状态行驶，则按照预设的调整幅度对加速度进行调整，控制行驶速度以预设的调整时长调整到限制速度；若车辆未保持全速行驶状态行驶，则不对加速度进行调整。本申请的车辆速度控制方法、系统及车辆，通过车辆保持全速行驶状态行驶时对所述加速度进行调整以控制所述行驶速度以预设的调整时长调整到所述限制速度，避免超速发生安全事故。
