Abstract

The invention relates to a method and system for controlling an active headrest in rear-end collision and a vehicle, which relate to the technical field of vehicle safety. The method comprises the following steps of judging whether each seat meets a headrest starting condition or not according to the state of a passenger on each seat in the vehicle, judging whether a rear-end collision hidden danger exists or not according to the motion parameters of the rear coming vehicle, and if judging that the rear-end collision hidden danger exists, controlling the seat headrest meeting the headrest starting condition to move to the set safety position. According to the embodiment of the invention, whether the rear-end collision of the rear coming vehicle occurs can be predicted, the active headrest is controlled to the set safe position in advance, and the whiplash injury of the headrest to the passenger in the rear-end collision accident is effectively reduced.

Description

technical field [0001] The present application relates to the technical field of vehicle safety, in particular to a method, system and vehicle for controlling an active headrest in a rear-end collision. Background technique [0002] With the rapid development of the economy, the complexity of road traffic has increased, the number of vehicles has increased year by year, and the number of traffic accidents has gradually increased. Among them, the main forms of vehicle collisions are frontal collisions, side collisions and rear-end collisions. And in the process of vehicle rear-end collision, due to the effect of inertia, there will also be relative motion between the driver and the headrest of the front vehicle and thus produce whiplash injury. Whiplash is a bone or soft tissue injury caused by the acceleration-deceleration mechanism of the neck from a rear or side impact. [0003] In order to reduce the risk of whiplash, an active headrest is provided in the related art. ...
