From brake-apply is started to there is the time of maximum braking force, referred to as brake action time；From occur maximum braking force to
Make the time that vehicle stops completely, referred to as continuous braking time.The distance that motor vehicle is run in these three times, referred to as motor vehicle
Brake the non-security phase.Shorten brake action time and the continuous braking time is related to designing and manufacturing problem, actually drives behaviour
Critical issue is how to shorten and control the reaction time in work.The inadequate skilled personnel of driving efficiency when driving vehicle, due to

In formula: L1--- motor-driven vehicle going distance (m) in driver reaction time；
V --- speed (km/h)；
T --- the reaction time (s).
It is approximately even moderating process by vehicle braking process, then the acceleration of the process is constant, by uniformly accelerated motion
Rule obtain range ability of the vehicle in braking process such as formula 4. shown in:
In formula: Sr--- braking distance (m)
V --- initial velocity (m/s)
G --- acceleration of gravity (m2)
--- coefficient of friction
I --- road longitudinal grade (going up a slope is "+", and descending is "-")
When road axial route face does not have the gradient, i.e., value is 0, then 5. above formula can arrange formula:
Therefore, during motor-driven vehicle going, driver has found that there is barrier in front, starts to brake, complete to motor vehicle
Stop, needed for stopping sight distance such as formula 6. shown in:
From formula 6. it will be seen that the operation of driver's error stepping on accelerator pedal influences very large, vehicle to stopping sight distance
Travel speed V and stopping sight distance S present quadratic function relation, this operation error leads to the increase of speed V, and then can make
It obtains stopping sight distance S to greatly increase, ultimately causes serious traffic accident.And present apparatus locking acceleration in error stepping on accelerator pedal is stepped on
Plate, which prevents car speed from increasing linkage braking system, to be made vehicle generate brake force abrupt deceleration vehicle or reduces by two aspects of speed
