The present disclosure is directed towards a system for implementing emergency braking. In particular, a computing system can obtain current trajectory data from a motion planning system of an autonomous vehicle. The computing system can determine whether an emergency braking flag within the current trajectory data is set to true based at least in part on the current trajectory data. The computing system can, in response to determining that the emergency braking flag within the current trajectory data is set to true, change a current braking mode of the autonomous vehicle from a first braking mode to a second braking mode. While in the second braking mode, the computing system can set a current acceleration value to the second maximum stopping rate. The computing system can transmit the current acceleration value for implementation by the autonomous vehicle.

Provided is a vehicle speed control device with respect to which the speed at which a centrifugal brake operates can be easily changed from the outside without disassembling the device. A brake drum 11 is fixed to a vehicle body 101a. A brake shoe 23 rotates around a rotary shaft 20 of the wheel 101c, and reduces the rotation speed of the wheel 101c as a result of coming into contact with an inner circumferential side face of the brake drum 11. A spring 24 prevents contact between the brake drum 11 and the brake shoe 23 when the rotation speed of the wheel 101c is lower than or equal to a predetermined speed, and permits contact between the brake drum 11 and the brake shoe 23 when the rotation speed of the wheel 101c exceeds the predetermined speed. A position change mechanism 25 is installed within the brake drum 11, and changes the position of an end of the spring 24 on one end side. A transmission mechanism 26 transmits a force that is input by an external operation to the position change mechanism 25 and drives the position change mechanism.
