Abstract

The invention provides a multi-target optimizing control method and system for an intelligent electric vehicle. The method comprises the steps that a driving safety target function, a passenger comfort level target function and a driving accuracy target function are established respectively according to the demands in three aspects of driving safety, passenger comfort level and driving accuracy ofthe intelligent electric vehicle; a mathematical model which allows performance targets to reach the optimum simultaneously is constructed according to the constraint conditions of an intelligent electric vehicle system; performance indicators of three aspects of the driving safety, passenger comfort level and driving accuracy of the intelligent electric vehicle are converted into a single indicator, and multi-target planning controlling model resolving is conducted by adopting a Pareto optimal multi-target optimization algorithm to obtain the optimal value. The control method and system havethe advantages that the contradiction among the driving safety, the passenger comfort level and the driving accuracy is solved by constructing a multi-target optimizing problem.

Description

technical field [0001] The invention belongs to the field of automatic driving of smart cars, and in particular relates to a multi-objective optimization control method and control system for smart electric cars. Background technique [0002] In recent years, with the rapid integration of computer, Internet, communication and navigation, automatic control, artificial intelligence, machine vision, high-precision maps and other high-tech and advanced automotive technologies, smart cars (or driverless cars, self-driving cars) have become A research hotspot in the field of automotive engineering in the world and a new driving force for the growth of the automotive industry. Automotive electronic systems have evolved from providing important on-board functions to advanced driver assistant systems (Advanced Driver Assistant Systems, ADAS), and even an important carrier for completely unmanned driving, from electromechanical components for perception and actuation to high-performan...
