Problems solved by technology

This device can reduce the collision loss of the vehicle to a certain extent, but triggers the electromagnetic anti-collision device according to the independent distance threshold. If the threshold is set too large, there is a problem that the vehicle itself can avoid collisions by braking without frequently activating the electromagnetic anti-collision device.

Embodiment Construction

[0052] In order to solve the technical problem of frequently starting the electromagnetic anti-collision device in the existing scheme, the present invention calculates in real time whether the vehicle will collide according to the speed and distance of the vehicle, and further judges whether the collision can be avoided through the deceleration of the vehicle before the collision occurs. If possible, the vehicle is braked to avoid a collision, thereby reducing the activation of the electromagnetic anti-collision device and reducing power consumption.

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the ...

Abstract

The invention belongs to the field of vehicle safety, and provides a vehicle anti-collision method, device and system. The method comprises: according to the speed of a vehicle and the speed of a front vehicle, determining whether the vehicle collides with the front vehicle or not, if yes, analyzing whether the vehicle decelerates at the maximum deceleration speed and still collides with the frontvehicle or not, and if not, controlling the vehicle to decelerate at the maximum deceleration speed, so that frequent starting of an electromagnetic anti-collision device is avoided, and then electric energy loss is reduced.

Description

technical field [0001] The present invention relates to the technical field of vehicle safety, more specifically, to a vehicle anti-collision method, device and system. Background technique [0002] Existing automobile safety includes two aspects of active safety and passive safety. Passive safety refers to the protection of the occupants in the car after an accident, and active safety refers to the safety system measures to avoid accidents. [0003] Active safety technology has become an important technology to improve automobile safety because it can avoid accidents under certain conditions. An existing active anti-collision device for a vehicle can activate the electromagnetic anti-collision device of the vehicle when the distance between the vehicle and the vehicle in front is less than a set threshold. This device can reduce the collision loss of the vehicle to a certain extent, but triggers the electromagnetic anti-collision device according to the independent distan...
