Description
Technical field
It is especially a kind of intelligent speed bump with TRT and its control the invention belongs to technical field of intelligent traffic
Method processed.
Background technology
In recent years, China's rapid economic development, car ownership increases sharply, and traffic accident quantity is also rising year by year.Vehicle
Hypervelocity is to cause the one of the main reasons of traffic accident, and deceleration strip is minimum and the most effective as car speed cost is reduced
Method, be widely used in daily life.Speed when vehicle is by deceleration strip is higher, is delivered to the vibration of vehicle body
It is more violent, but even if vehicle passes through deceleration strip with low-down speed, still have larger vibration and be delivered to vehicle body, shadow
Ring the comfortableness of vehicle, can also cause fatigue damage to chassis system of vehicle etc., influence the service life of vehicle, this also against
The original intention of deceleration strip is set.Meanwhile, when vehicle passes through deceleration strip, a part of kinetic energy of vehicle can be converted into the vibrations to vehicle
Impact, makes vehicle produce vibration, and the energy of jerk is converted into heat energy eventually through shock absorber, although can so drop
The speed of low vehicle, but this portion of energy is but wasted, if not influenceing deceleration strip basic training by certain device
To using, its effect is also considerable to the energy for being wasted this part on the premise of energy.
The content of the invention
The energy of the jerk produced during the invention aims to using vehicle by deceleration strip, while ensureing car
Low speed passes through comfortableness during deceleration strip, and a kind of intelligent speed bump and its control method with TRT for providing,
When vehicle is more than speed limit by the speed of deceleration strip, clutch engagement, the motion of deceleration strip drives electrical power generators, realizes
Recycling and the jerk larger to vehicle generation to energy, when vehicle is less than or equal to speed limit by the speed of deceleration strip
When, clutch is separated, and the motion of deceleration strip no longer drives generator, and jerk is smaller, it is ensured that the comfortableness of vehicle.
