生态驾驶的最优控制问题，即使用最少的燃料或电能驾驶车辆，在智能汽车文献中受到了广泛关注，最近提出了许多生态驾驶自适应巡航控制系统（eco-ACC）。在本文中，我们考虑了最近引入的“自然主义”生态acc方法，该方法旨在在车辆跟随中提供类似人类的行为。对于这种eco-ACC，我们表明，在汽车跟随和启停交通场景下，eco-ACC不仅有利于自我车辆，也有利于后面的车辆。为了了解是否有可能进一步降低总能耗，我们对eco-ACC系统进行了扩展，采用最优控制公式，假设其按照智能驾驶员模型（IDM）运行，该公式还可以最大限度地减少后续车辆的能量损失。这在能源使用上有一些微小的减少，但令人惊讶的是，对于一个根据IDM行为的追随者来说，自然生态acc似乎是最小化自我车辆及其追随者总能量损失问题的最优选择。
The optimal control problem of eco-driving, driving a vehicle using a minimal amount of fuel or electrical energy, has received much attention in the intelligent vehicles literature with many recent proposals for eco-driving adaptive cruise control systems (eco-ACC). In this paper, we consider a recentlyintroduced ‘naturalistic’ eco-ACC approach, which was designed to give human-like behaviour in vehicle following. For this eco-ACC, we show that in car following and start-stop traffic scenarios, the eco-ACC benefits not only the ego vehicle but also a further following vehicle. To see if further reductions to total energy consumption are possible, we extend the eco-ACC system with an optimal control formulation that also minimises energy losses of the following vehicle assuming it behaves according to the intelligent driver model (IDM). This gives some minor reductions in energy usage but surprisingly, for a follower that behaves according to the IDM, the naturalistic eco-ACC appears to be nearly optimal for the problem of minimising total energy loss of both the ego vehicle and its follower.
