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.

    本发明公开一种基于加速度的车速限制控制方法、控制系统及车辆,所述车速限制控制方法包括:S1、获取车辆加速度与车辆限速时介入门槛车速的对应关系;S2、确定车速限值,实时监测车辆当前加速度与速度值;S3、确定当前加速度值对应的介入门槛车速,并获取车速限值与介入门槛车速的第一车速差值;S4、对比第一车速差值与车辆当前速度值,确定车辆当前行驶模式;S5、若车辆进入车速限制模式,获取从当前介入门槛车速缓慢趋近车速限值的加速目标曲线;S6、基于加速目标曲线中的目标车速,对车辆当前实际车速进行所述目标车速的追随控制。本发明公开的技术方案,其能够控制车速缓慢接近但不超过最高限值,满足限速要求的同时保证车辆运行的平稳性。
