Problems solved by technology
At the same time, due to the steering clearance of the steering system itself, the steering system cannot immediately drive the wheels to rotate after active steering is performed, or the driver rotates the steering wheel, which is not conducive to driving safety.
[0003] However, there is no solution in the prior art that can avoid the occurrence of the above-mentioned security risks.

The invention discloses a method and device for controlling obstacle avoidance of an automobile and an automobile, wherein the method comprises the following steps of: detecting a real-time relative distance between the automobile and an obstacle; judging whether the real-time relative distance reaches a preset risk level; if so, sending a steering clearance adjusting signal to EPS so that the EPScan perform clearance adjusting processing according to the steering clearance adjusting signal; wherein the gap adjustment signal comprises an adjusted rotation angle size and a rotation angle direction; and after the clearance adjustment processing is finished, controlling the automobile to avoid the obstacle. According to the scheme, when an emergency situation is encountered, before the obstacle avoidance is carried out, the clearance adjustment processing is carried out, so that the steering idle stroke in a normal obstacle avoidance process is reduced, and the subsequent obstacle avoidance process is sensitive and effective; compared with the prior art that the obstacle avoidance processing measures are directly adopted to avoid the obstacle, the scheme can reduce the collision risk.
Description
technical field [0001] The invention relates to the technical field of vehicle control, in particular to a control method and device for vehicle obstacle avoidance and a vehicle. Background technique [0002] Emergency Steering Pilot / Assist (ESP / ESA for short) can reduce the damage of a collision through active steering or assisted steering when a collision is inevitable. At the same time, due to the steering gap in the steering system itself, the steering system cannot drive the wheels to rotate immediately after active steering is performed, or the driver rotates the steering wheel, which is not conducive to driving safety. [0003] However, there is no solution in the prior art that can avoid the above-mentioned potential safety hazards. Contents of the invention [0004] In view of the above problems, the present invention is proposed to provide a control method, device and vehicle for obstacle avoidance of automobiles which overcome the above problems or at least par...
