Problems solved by technology
At present, vehicle safety protection mainly focuses on the protection of vehicle forward collision and rear collision. For frontal or rear collision, the body is designed with a large buffer space. However, for side collision, even if there is a good enough body design Materials are used to make buffer energy-absorbing structures, and the side walls of the vehicle body provide little buffer space for lateral collisions, so the lateral protection of the vehicle is far weaker than the forward and rearward protection of the vehicle. more damage

Embodiment Construction
[0053]In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0054] The inventor found through research that the current vehicle safety protection mainly focuses on the protection of the vehicle's forward collision and rear collision. For frontal or rear collisions, the body is designed with a large buffer space. However, for side collisions, the body design , even if there are enough good materials to make...

The invention discloses a method and device for vehicle side collision protection and equipment. The method for the vehicle side collision protection comprises the steps that a first distance value between a lateral obstacle of a vehicle and the vehicle at a first moment and a second distance value between the lateral obstacle of the vehicle and the vehicle at a second moment are obtained; according to the distance difference between the first distance value and the second distance value as well as the time difference between the second moment and the first moment, the speed at which the lateral obstacle of the vehicle approaches the vehicle is obtained; according to the speed at which the lateral obstacle of the vehicle approaches the vehicle and the second distance value, the estimated collision time between the vehicle and the lateral obstacle of the vehicle is obtained; and if the expected collision time is less than a preset time threshold, a vehicle body is controlled to be lifted. It can be seen that side collision can be effectively identified according to judgment of the calculated estimated collision time, and the penetrability of a vehicle wall during side collision canbe effectively reduced by lifting the height of the vehicle body, so that the personal safety of passengers is protected.
Description
technical field [0001] The invention relates to the technical field of automobile safety and control, in particular to a method, device and system for vehicle side collision protection. Background technique [0002] Along with the increase of automobile quantity, the raising of automobile speed, automobile traffic accident is also more and more, more and more serious. According to the statistics of traffic data, the collision of vehicles will cause disastrous personnel and huge property losses every year, and may cause serious traffic delays at the same time. [0003] Vehicle collisions are generally divided into forward collisions, side collisions and rear collisions, etc. Among them, the cause of side collisions is often that the driver of the vehicle fails to detect the vehicle passing from the side in time or The estimated speed of the vehicle is wrong. At present, vehicle safety protection mainly focuses on the protection of vehicle forward collision and rear collisio...
