Brain-computer interacted and wire-controlled intelligent steering system and emergency obstacle avoidance method thereof

Abstract

The invention discloses a brain-computer interacted and wire-controlled intelligent steering system and an emergency obstacle avoidance method thereof. The system involves a brain wave gathering module, a brain wave processing module, a driver intention recognizing module, a steering path planning module, a pre-aiming module, a vehicle sensor module, a wire-controlled steering module and an informing module. According to the system, on the basis of the steering intention of the brain of a driver and an actual road condition, a working mode is judged, a steering path is comprehensively planned,the wire-controlled steering module is controlled to complete emergency obstacle avoidance, the operation requirements of the driver can be met to the maximum extent under the condition that the stability and safety of steering are ensured, and good human-computer interaction experience is obtained.

Description

technical field [0001] The invention belongs to the technical field of automobile steering systems, and specifically refers to a brain-computer interaction wire-controlled intelligent steering system and an emergency obstacle avoidance method thereof. Background technique [0002] In emergency conditions, due to factors such as the driver's mental stress, lack of driving experience, and excessive road environment interference, there is often a large deviation between the driver's actual operation and the driver's psychological expectation, resulting in a dangerous situation. Even if the driver completes the emergency avoidance operation completely in accordance with the psychological expectation, the driver will not be able to fully obtain and judge the overall traffic situation instantaneously, and cannot plan the best vehicle route. With the development of automotive intelligent driving technology, multi-sensor fusion technologies such as cameras, millimeter-wave radars, a...

Problems solved by technology

[0004] Aiming at the deficiencies of the above-mentioned prior art, the purpose of the present invention is to provide a brain-computer interaction intelligent steering system and its emergency obstacle avoidance method, so as to solve the problem that there is no better integrated driving in the existing automobile emergency obstacle avoidance technology. The driver's intention and the intelligent vehicle controller cannot take into account the driver's psychological state and the vehicle's intelligent control requirements. The present invention reads the driver's driving intention and selects the working mode of the steering actuator when the car avoids obstacles under emergency steering conditions. To overcome the problems existing in the prior art
