Problems solved by technology

However, at present, most AEB anti-collision algorithms only distinguish between low vehicle speed and high vehicle speed, and do not distinguish whether the obstacle is a static obstacle or a dynamic obstacle.

Abstract

The invention discloses a vehicle brake control method based on dynamic and static judgment of an obstacle. The method comprises the following steps of step 101, detecting a distance difference deltadbetween a current vehicle and a front obstacle; step 102, acquiring a running distance d of the current vehicle; step 103, judging a dynamic state and a static state of the obstacle, namely comparingthe distance difference deltad with the running distance d by a comparison module, if the deltad is approximately equal to d, considering that the front obstacle is static and entering the step 104;if the deltad is less than d, considering that the front obstacle is dynamic and entering the step 105; step 104, carrying out static brake; and step 105, carrying out dynamic brake. The method is simple and reasonable in design; a computer identifies whether the front obstacle in a following process is a static obstacle or a dynamic obstacle according to a dynamic and static algorithm, the different brake time can be reserved according to the dynamic state and the static state of the front obstacle, the brake of the mechanism is performed, the premature or late braking is avoided, and the reliability of an automatic emergency brake system is improved.

Description

technical field [0001] The invention belongs to the technical field of automatic driving, and in particular relates to a vehicle driving control method based on dynamic and static judgment of obstacles. Background technique [0002] With the rapid development of our country's economy, the increasing national income and living standards, and the continuous improvement of traffic conditions, these have made private cars gradually popular in ordinary families. Vehicles on the road cause personal injury or property damage due to the driver's fault or accident. Incidents occur frequently. In order to avoid car collision accidents, mainstream automakers and technology suppliers in the market basically provide forward collision warning systems and automatic emergency braking systems. [0003] The Automatic Emergency Braking (Autonomous Emergency Break, AEB) system uses modern sensor technology to detect the surrounding environment of the vehicle and the driving state of the vehicle...
