Intelligent network four-wheel independent steering and independent drive electric vehicle emergency obstacle avoidance system

Abstract

The invention discloses an emergency obstacle avoidance system for an intelligent network-connected four-wheel independent steering and independent drive electric vehicle, aiming to improve the obstacle avoidance ability of the electric vehicle by using vehicle-to-vehicle interaction technology. The vehicle-to-vehicle interaction module of the vehicle-mounted vehicle-to-vehicle interaction module in the vehicle can switch between different modes according to the risk of collision between the vehicle and the obstacle in front of the vehicle in each case of normal function, partial function failure and function failure. Obstacle avoidance mode. The vehicle can receive the movement information of other vehicles through the vehicle-to-vehicle interaction module to make more reasonable obstacle avoidance decisions; other vehicles can also receive the warning information sent by the vehicle, creating favorable conditions for the vehicle to avoid obstacles. Especially in an emergency situation where the vehicle cannot avoid a collision through braking measures, the emergency obstacle avoidance system receives the path planning information of other vehicles through the vehicle-to-vehicle interaction module, and judges whether there is a possibility of changing lanes to avoid obstacles through the decision-making module. Further reduce the risk of collision.

Description

technical field [0001] The invention belongs to the field of intelligent networked automobile safety, relates to vehicle active anti-collision technology, and specifically relates to an intelligent networked four-wheel independent wire-controlled steering and independent wire-controlled drive electric vehicle emergency obstacle avoidance system, which uses vehicle-to-vehicle information interaction technology to improve The obstacle avoidance ability of the car, and then improve the driving safety of the car. Background technique [0002] With the continuous maturity of vehicle industry technology, vehicles are used in all aspects of human production and life. Vehicle driving requirements and road conditions are becoming more and more complex, which puts forward higher requirements for the design of vehicle structure and control strategy. Therefore, a new type of four-wheel independent steering independent drive vehicle is proposed. Compared with traditional vehicles, it ha...

Problems solved by technology

At present, the existing emergency obstacle avoidance system based on four-wheel independent steering and independently driven electric vehicles has the following problems: 1) Only when the vehicle is in the adjacent lanes on both sides of the vehicle and there are no other vehicles, will the lane change obstacle avoidance measures be considered , failed to consider the possibility of changing lanes and avoiding obstacles when there are other vehicles driving in the adjacent lane; 2) The decision-making module of the vehicle only obtains relevant information from the perception module of the vehicle to select the obstacle avoidance measures, and fails to consider the impact of the surrounding traffic conditions on The impact of obstacle avoidance safety; therefore, when taking obstacle avoidance measures, there is still a greater risk
