Cooperative adaptive cruise control

Adaptive Cruise Control (ACC) enables automatic following of a preceding vehicle, based on measurements of the inter-vehicle distance xr,i and the relative velocity ˙ xr,i. Commonly, a radar is used for these measurements, see Figure 1. Decreasing the inter-vehicle distance to a small value of only several meters is expected to yield an increase in traffic throughput [1]. To enable this for a string of vehicles, a platoon, inter-vehicle communication is required besides the radar data [2]. This is called Cooperative ACC (CACC)
