Automobile collision avoidance system for vulnerable road users and control method thereof

Abstract

The invention discloses an automobile collision avoidance system for vulnerable road users and a control method thereof, and relates to the field of vehicle driving safety. A decision module receives information collected by a sensing module and makes a corresponding scheme, and an execution module is used for executing the scheme of the decision module; the decision module receives the automobile motion information, the motion information of surrounding targets and the road condition information acquired by the sensing module, judges whether a dangerous target exists or not, determines a collision avoidance scheme after evaluating the feasibility of active braking and active steering, and calculates the expected braking pressure, the expected throttle opening and the expected steering wheel turning angle; the execution module is based on a control signal of the decision module, when the automobile is actively braked, a brake and a throttle valve controller work cooperatively, and braking deceleration is output; and when the automobile actively steers, the steering system enables the automobile to steer along the planned path. Active braking or active steering operation is adopted, collision between the automobile and a dangerous target is avoided to the maximum extent, and therefore the road safety is remarkably improved.

Description

technical field [0001] The invention belongs to the field of vehicle driving safety, and in particular relates to an automobile collision avoidance system for vulnerable road users and a control method thereof. Background technique [0002] Vulnerable road users refer to the participants who are vulnerable due to lack of safety protection in the road traffic environment, mainly including pedestrians, two-wheeler users and three-wheeler users. Relevant statistics show that the death toll of vulnerable road users accounts for more than half of the global road traffic accident deaths and causes huge economic losses. Therefore, the safety of vulnerable road users has received widespread attention from the society. [0003] The road scene in our country is complex, and there are many intersections, so it is very common for vulnerable road users to cross the road, and the vulnerable road users have the characteristics of flexible movement, random location, etc., and only rely on t...

[0003] The road scene in our country is complex, and there are many intersections, so the phenomenon of vulnerable road users crossing the road is very common, and the disadvantaged road users have the characteristics of flexible movement, random location, etc., and only rely on the driver to operate the car emergency. Avoiding vulnerable road users, poor collision avoidance
