TL;DR: The simulation system for vehicle speed analysis of rear-end collision was finished with Visual C and the result indicates that the simulation system is adaptive for analysis of vehicle collision.
Abstract: As an accident analysis tool, the simulation system of vehicle collision are developed. On the basis of momentum conservation, speed analysis model for vehicle rear-end collision was established. Then the analysis algorithm was designed. Based on the function structure design, the simulation system for vehicle speed analysis of rear-end collision was finished with Visual C. An actual example was also applied in the system. The simulation result is very closely to actual condition. It indicates that the simulation system is adaptive for analysis of vehicle collision.

TL;DR: In this paper, a rear shock absorber of a heavy vehicle is designed to absorb impact force generated by a rear colliding vehicle to prevent the impact force from returning to the rear collision, thereby absorbing and dispersing the impact forces by sequential distortion of the multiple plates during a rear collision.
Abstract: The present invention relates to a rear shock absorber of a heavy vehicle. The objective of the present invention is to provide the rear shock absorber of a heavy vehicle, wherein multiple plates having space portions are overlapped to effectively absorb impact force generated by a rear colliding vehicle to prevent the impact force from returning to the rear colliding vehicle, thereby absorbing and dispersing the impact force by sequential distortion of the multiple plates during a rear collision.

TL;DR: In this article, a method for preventing rear-end collision when driving on a highway in a foggy day is proposed. But the method is limited to the case of a single vehicle.
Abstract: The invention relates to the field of safely driving in a highway, in particular to a method for preventing rear-end collision when driving on the highway in a foggy day. The method adopts a scheme of comprising a vehicle navigation system, two sets of laser electronic range finders, a microprocessor, a laser signal lamp, a voice broadcasting device, a humidity sensor and a control system, wherein the vehicle navigation system, the two sets of laser electronic range finders and the control system are separately connected with the microprocessor; and the laser signal lamp, the voice broadcasting device and the humidity sensor are connected with the control system. Through the adoption of the method disclosed by the invention, a driver can visually observe front road condition and rear road condition from a map of the vehicle navigation system, and adjust the vehicle speed of the current vehicle according to changes of the distance between a front vehicle and the current vehicle and the distance between a rear vehicle and the current vehicle on the map, so that the driver can judge more accurately; besides, the laser signal lamp and the voice broadcasting device can remind the driver of the current vehicle, a driver of the front vehicle and a driver of the rear vehicle to pay attention to driving on the highway, so that the occurrence of the traffic accidents can be effectively avoided; the method disclosed by the invention is simple to operate and notable in effect.

TL;DR: In this paper, a method for acquiring the number of usage times of a vehicle rear-end collision-proof technique, and a brake light system, is presented, which includes: recording an inter-vehicle distance threshold from the tail of a user vehicle to the head of a rear vehicle; detecting whether the inter-Vehicle distance between the user vehicle and the rear vehicle is less than the inter vehicle distance threshold, and if not, staying as is; and if so, automatically turning on the brake light to prompt the rear vehicles to keep their distance, and sending technical usage
Abstract: The invention belongs to the technical field of electronics, and provides a method for acquiring the number of usage times of a vehicle rear-end collision-proof technique, and a brake light system. The method comprises: recording an inter-vehicle distance threshold from the tail of a user vehicle to the head of a rear vehicle; detecting whether the inter-vehicle distance between the user vehicle and the rear vehicle is less than the inter-vehicle distance threshold from the tail of the user vehicle to the head of the rear vehicle; if not, staying as is; and if so, automatically turning on the brake light to prompt the rear vehicle to keep their distance, and sending technical usage data to a data collection end pre-set by a manufacturer. In the invention, by detecting the inter-vehicle distance between the user vehicle and the rear vehicle, and automatically turning on the brake light to actively prompt the rear vehicle to keep their distance, a vehicle rear-end collision can be prevented, and at the same time, it is convenient for the manufacturer to timely and effectively acquire utilisation conditions about the related technique.
