[Means for Solving the Problems]

  All land-based vehicles such as automobiles rely on the brakes to reduce the traveling speed of the vehicle. However, if a general vehicle is running on a flat road, the vehicle's network The contact surface where the tires of the vehicle come into contact with the road surface of the flat road The product, or maximum stiction, is approximately constant. That is, the vehicle At the same speed, the distance from emergency braking to complete stopping is generally fixed. However, the average driver is always influenced by his driving habits and experiences, The driving speed and the distance from the vehicle in front are almost the same. However, it is the same road However, if you don't keep a longer braking distance than usual driving, for example in the rain or Is in an emergency due to road conditions such as going down a slope and changes in mental and emotional conditions. In case of accident, the brake will not be in time and an accident will occur, and the loss caused by this will be lost. It will leave a big regret in your life.

[0003]   In light of the above, the applicant is aware that the general car driver may have different road conditions and weather conditions. If there is a change in mental status or emotions, the reaction may be delayed and an accident may occur. Therefore, as a result of repeated research based on many years of experience and improvements, It came to create a brake assist device.
