Personalized Car-Following Control Based on a Hybrid of Reinforcement Learning and Supervised Learning
IEEE Transactions on Intelligent Transportation Systems(2023)
摘要
With the development of intelligent vehicles, more research has focused on achieving human-like driving. As an important component of intelligent vehicle control, car-following control should ensure safety, tracking, comfort while considering the acceptance of human drivers. In this paper, we propose a car-following control strategy
$\boldsymbol {\pi }_{ \boldsymbol {Hybrid}}$
based on a hybrid of reinforcement learning (RL) and supervised learning (SL). RL is used to achieve multi-objective collaborative optimization in car-following control, and SL is used to achieve human like car-following. Through the complementary advantages of the two learning methods,
$\boldsymbol {\pi }_{Hybrid}$
can achieve high performance car-following while matching the personalized car-following characteristics of human drivers. RL is used as the main framework of
$\boldsymbol {\pi }_{Hybrid}$
. In addition, the personalized car-following reference model (PCRM) of human drivers based on Gaussian mixture regression, and the motion uncertainty model of preceding vehicle (MUMPV) based on the sequence-to-sequence network are established and incorporated into the RL framework. PCRM can lead
$\boldsymbol {\pi }_{Hybrid}$
to learn the different characteristics of human drivers, and improve the anthropomorphism of
$\boldsymbol {\pi }_{Hybrid}$
; MUMPV enables
$\boldsymbol {\pi }_{Hybrid}$
to consider the dynamic changes of the traffic environment and to become more robust.
$\boldsymbol {\pi }_{Hybrid}$
is trained and tested on High D dataset, and the generalizability verification is based on the self-built real vehicle data collection platform. The results show that
$\boldsymbol {\pi }_{Hybrid}$
can match human drivers’ personalized car-following characteristics and can outperform human drivers in safety, comfort, and tracking of the preceding vehicle.
