Part 1 Introduction to vehicle platooning
Vehicle platooning is a promising application in the transportation industry to improve the safety, efficiency, and comfort for passengers with innovative capabilities.
1.1 How Vehicle Platooning Works
Vehicle platooning is a convoy of vehicles with a lead vehicle driven with a professional driver and other vehicles closely followed.
The main goals of vehicle platooning are: (1) efficient transport such as increase the vehicle density on the highway (2) safe transport using various techniques such as obstacle detection, adaptive cruise control and avoidance, automatic car parking.
Most vehicle platooning systems are built on a linear configuration.
The vehicles in the platoon will move following the action of the lead vehicle. Each vehicle has to coordinate its direction, speed and distance with the vehicle in front. All the vehicles in the platoon are relative independent and can move out the platoon. The driver of the vehicles in the platoon can relax as most driving is done by the professional driver in the lead vehicle .
1. 1. 1 Vehicle Control
Longitudinal control and lateral control is the most two important problems related to the control of the vehicle platooning systems .
Longitudinal control is actually to control the speed of vehicles and the distance between the vehicles in the platoon. The longitudinal control will maintain a stable distance between the front vehicle and the following vehicle with a couple of inches more or less. The speed, acceleration, and deceleration of the vehicles will be programmed in advance according to the speed limits as well as maximum acceleration and deceleration rate based on the road geometry. The longitudinal control is maintained by radio communication and radar among the vehicles. The velocity and separation is constantly updated and monitored .
Lateral control is to align... [continues]
