The invention provides a speed control method and system of an autonomous vehicle, and the autonomous vehicle. The method is applied to the autonomous vehicle (100,800). The autonomous vehicle (100,800) comprises speed planning devices (501,803). The method comprises the steps of in an automatic driving process of the autonomous vehicle (100,800), controlling the speed planning devices (501,803) to acquire the current treading depth of an accelerator pedal (801) of the autonomous vehicle (100,800) so that the speed planning devices (501,803) generate the expected speed of the autonomous vehicle (100,800) according to the current treading depth of the accelerator pedal (801) (S201); acquiring the expected speed of the autonomous vehicle generated by the speed planning devices (501,803) (S202), and adjusting the driving speed of the autonomous vehicle (100,800) according to the expected speed of the autonomous vehicle (100,800) (S203). The invention further includes a speed control system (500) of the autonomous vehicle, and the autonomous vehicle (100,800). The expected speed is set through the accelerator pedal (801) for adjusting the driving speed of the autonomous vehicle. The accelerator pedal (801) can be operator by a driver through a foot, thereby realizing no requirement for attention diversion of the driver, facilitating setting of the expected speed, and improving safety in automatic driving of the autonomous vehicle.

    一种自动驾驶车辆的速度控制方法、系统和自动驾驶车辆,此方法应用于自动驾驶车辆(100,800),自动驾驶车辆(100,800)包括速度规划装置(501,803),此方法包括:在自动驾驶车辆(100,800)自动驾驶过程中,控制速度规划装置(501,803)获取自动驾驶车辆(100,800)的油门踏板(801)踩下的当前深度,使速度规划装置(501,803)根据油门踏板(801)踩下的当前深度,生成自动驾驶车辆(100,800)的期望速度(S201);获取速度规划装置(501,803)生成的自动驾驶车辆的期望速度(S202),根据自动驾驶车辆(100,800)的期望速度,调整自动驾驶车辆(100,800)的行驶速度(S203)。还包括一种自动驾驶车辆的速度控制系统(500)和自动驾驶车辆(100,800)。通过油门踏板(801)来设定期望速度以调整自动驾驶车辆的行驶速度,油门踏板(801)由驾驶员通过脚即可操作,无需分散驾驶员的注意力,使得期望速度的设定更加便利,提高了自动驾驶车辆的自动驾驶的安全性。
