2 results about "Braking distance" patented technology

The present disclosure discloses a brake control system for use in a vehicle and a control method thereof. A brake control system may be configured to include a brake pad for braking the vehicle by pressing a brake disc provided in the vehicle, a measuring apparatus for measuring the vehicle speed, the wear level of the brake pad, the traveling distance of the vehicle, the braking distance of the vehicle, and the braking pressure applied by the brake pad to the brake disc at braking, and a controller connected with the measuring apparatus and for controlling an operation of the brake pad. The controller may compare an initial braking distance, which is a design value of the braking distance before initial traveling of the vehicle, with a current braking distance, which is a braking distance after traveling of the vehicle during a certain duration, and increase the braking pressure of the brake pad in response to the amount of increase in the braking distance, when the amount of increase in the braking distance, which is a difference value between the current braking distance and the initial braking distance, is out of a setting range. The brake control system may transmit and receive a wireless signal in a mobile communication network constructed according to 5G (Generation) communication.

The invention provides a rubber composition for improving the performance of a tire on an ice and snow field. The rubber composition comprises the following components: 100 parts by weight of a rubber component; 23-25 parts by weight of carbon black; 32-35 parts by weight of white carbon black; 33-35 parts by weight of aromatic oil; 2-5 parts by weight of an active agent; 2-6 parts by weight of an anti-aging component; 1-2 parts by weight of a processing aid; 2-10 parts by weight of glass flakes; 1.5-3 parts by weight of a vulcanizing agent; and 0.4-2.5 parts by weight of a vulcanization accelerator. The rubber component is prepared from 60-70 wt% of natural rubber, 10-20 wt% of butadiene rubber and 15-25 wt% of butadiene styrene rubber. The tread formula composition disclosed by the invention mainly contains 2-10 PHR glass flakes, so that the area of contact with an ice and snow road surface can be increased, the gripping performance can be improved, and the braking distance can be shortened. Meanwhile, the tire is a nailing-free tire, so that the comfort of a vehicle and the like is facilitated.
