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

Abstract

The invention discloses a brain-computer interaction wire-controlled intelligent steering system and its emergency obstacle avoidance method, comprising: a brain wave acquisition module, a brain wave processing module, a driver's intention recognition module, a steering path planning module, a preview module, a vehicle Sensor module, steer-by-wire module, notification module; the system judges the working mode according to the steering intention of the driver's brain and the actual road conditions, comprehensively plans the steering path, controls the steer-by-wire module to complete emergency obstacle avoidance, and ensures stable and safe steering Under this condition, the driver's operation needs can be followed to the greatest extent, and a good human-computer interaction experience can be 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...
