Intelligent driving automobile motion planning energy-saving control method

The endurance mileage of an electric automobile is still an important factor for limiting the development of the electric automobile, and the invention discloses an energy-saving control method for motion planning of an intelligent driving automobile in order to solve the problems of energy output optimization and efficient energy recovery during braking of the automobile in the driving process. Comprising the steps that a model prediction control module predicts driving information at the next moment by taking safe and stable driving or braking of a vehicle as a control target and taking the maximum acceleration/gravitational acceleration during acceleration and deceleration of the vehicle as a constraint, and transmits the predicted driving information at the next moment to a two-stage dynamic planning module to provide data support for the two-stage dynamic planning module; and the two-stage dynamic planning module is used for obtaining an optimal decision of optimal energy output or recovery according to
