The invention provides an electric car drive control method based on road information. The method comprises the following steps: acquiring external information, wherein the external information contains position information and time state information of a next traffic light; acquiring car self-information, wherein the car self-information includes gear information, acceleration information or brake information and current car speed; calculating the distance from the current position of the car to the position of the ahead traffic light according to the time state information of the next traffic light, calculating the time for reaching the position of the traffic light ahead according to the current car speed in conjunction with the current acceleration information or brake information; calculating a target car speed, notifying a driver of the calculated target car speed, and instructing the driver to drive a car according to the target car speed. According to the method, by introducing the position of the traffic light and the time state information of the traffic light, the time for frequent accelerating and decelerating the car speed, and the idle waiting time which are for adapting to the traffic light ahead can be shortened, and the efficiency of a drive system can be improved.
