Abstract
The utility model discloses a system for automatically maintain safe distance between cars, which comprises a mechanical part, a control part and a ranging part. The mechanical part includes a foot pedal, a drawbar, a cylinder liner with racks and a gear, wherein the foot pedal is movably connected with the drawbar; the drawbar is connected with the cylinder liner with the racks; the cylinder liner is meshed with the gear; and the gear is connected with a motor. The control part is a singlechip controller. The ranging part is a laser ranger. The system provided by the utility model has the benefits that the total response time of the laser ranger, the singlechip and the motor is not larger than 10 m/s; obstacles in front of cars can be timely detected; and the safety braking distance can be accurately calculated by the singlechip.
Description
Technical field
The utility model relates to a kind of brake system, specifically is a kind of system that maintains safe distance automatically.
Background technology
At the car of running on expressway, because the fast more braking distance of the speed of a motor vehicle is long more, if the front vehicles cataphoretic failure, the driver is long to the reaction time that begins to brake from seeing obstacle.Be more than the 200ms averaging time.The brake safety distance can't be accurately predicted,,, also a series of knocking into the back certainly will be caused even if reaction is fast again if speed is excessive.Can't dynamically control the speed of a motor vehicle, if automobile travels on sky way, speed is excessive before going into to bend, and will inevitably hit fence or the people or the tree at bend place.When automobile was parked on the slope, if forgotten to pull the hand brake, because the existence in inter-agency various gaps, automobile can glide gradually, until hitting obstacle.
The utility model content
In order to overcome above-mentioned defective, the utility model provides the system that maintains safe distance automatically.
The technical solution of the utility model is achieved in that the system that maintains safe distance automatically, comprise mechanics, control part and ranging unit, described mechanics comprises stretcher, pull bar, band tooth bar cylinder sleeve and gear, described stretcher flexibly connects with pull bar, the cylinder sleeve of pull bar connecting band tooth bar, the cylinder sleeve and the gear interlock of band tooth bar, gear connects motor; Described control part is a singlechip controller; Described ranging unit is a laser rangefinder.
The beneficial effects of the utility model are: the response time of laser rangefinder response time+micro controller system response time+motor is no more than 10ms in the native system.And can real-time detection the place ahead obstacle.Accurately calculate the brake safety distance by micro controller system, when accident appearred in the place ahead vehicle, deceleration system started automatically, and when distance obstacle 2m, speed is kept to 0.When car travels in the comparatively intensive city center of vehicle flowrate, the distance of front and back car will remain on more than the 1m.Apomecometer can dynamically be measured the distance according to the place ahead obstacle, can underspeed automatically before going into to bend, and only measure the distance of dead ahead obstacle, car that is travelled in both sides or static obstacle, do not do any action, needn't worry to close on the influence and the problem of overtaking other vehicles of head-on sailing the automobile that comes on the highway.Automobile under when sliding into apart from obstacle 1m speed be kept to 0.Or when in the static automobile dead ahead 1m obstacle being arranged, automobile can't start.The distance of returning when apomecometer less than safety shut-down apart from the time, the voice suggestion driver is apart from the place ahead obstacle xx rice, automatic speed reducing system of vehicle starts, the electric motor starting of controller control simultaneously, the beginning of slowing down.In particular cases, when not using deceleration system, can (ON Off) turns off this system by enabling switch.
