String stability and the traffic flow stability are the two important characteristics of ICVPS, as mentioned in Chap. 1. External disturbances have a good influence on the spacing error and vehicle error between vehicles. But string stability can ensure the external disturbances of upstream vehicles will not be amplified and propagated among downstream vehicles of the platoon system. So that the risk of collision can be avoided, and the safety of longitudinal driving of the platoon can be achieved. For the traffic flow stability, which can avoid the situation that the when traffic flow density is increasing and the traffic flow velocity will decrease under the influence of disturbances. Thus, the traffic flow stability can ensure that the threat of traffic congestion be eliminated. From the perspective of control, the string stability depends heavily on the inter-vehicle spacing policy and the controller design. The characteristics of traffic flow stability are closely related to the steady state process of the vehicle platoon system. And the inter-vehicle spacing policy will also directly affect the stability of the traffic flow of the platoon system. In order to ensure the string stability and traffic flow stability of the vehicle platoon system, scholars focus on the inter-vehicle spacing error policy, such as constant spacing policy, constant time headway spacing policy, and exponential spacing policy, etc (as mentioned in Chap. 1).
