The invention discloses an electric vehicle kinetic energy recovery system and method based on traffic signal lamp adaptive adjustment. The system comprises a signal lamp sensing module, an environment sensing module, a driver intention algorithm module, a kinetic energy recovery decision module and a kinetic energy recovery execution module. Acquiring front traffic signal lamp data in real time through a camera, and analyzing to obtain the traffic signal lamp state of the current intersection; the distance between the front vehicles and the front stop line distance are obtained through a camera, a millimeter wave radar and a laser radar; judging and outputting a driver intention according to the driver behavior action; outputting a kinetic energy recovery strategy according to the current signal lamp state, the environment data and the intention of the driver; and the kinetic energy recovery action is executed according to the strategy output by the kinetic energy recovery decision module. According to front real-time traffic signal lamp information, the kinetic energy recovery force and time are adjusted in a self-adaptive mode, and therefore the purposes of efficiently recovering energy and improving the driving performance are achieved.
