Notification number is that the Chinese patent of ZL01129767.0 has been announced another kind of " control method of automobile-used electric eddy speed reducing ", its purpose is based on the electric eddy current rail brake for vehicle deceleration control method of Power Electronic Technique, this method can make the current vortex braking force do stepless adjustment in almost nil minimum value in peaked scope, easy and simple to handle, good stability.
Application number is 200810020499.7, the patent application that name is called " a kind of automobile foundation brakes and retarder united controller and control method " discloses the united controller and the control method of a kind of current vortex retarder and automotive friction drg, with various on-off signal input circuits, running speed pulse signal input circuit, automobile brake pedal position input circuit links to each other with microcomputer, microcomputer has a plurality of defeated IV output interfaces, central processor CPU receives the digital signal that input/output interface transmits by internal bus, the numeric results of the count results of counting machine and A and D converter ADC, and behind logic determines and numerical operation, control signal is transferred out, when chaufeur does not have connection not jointly control switch, microcomputer is not received the on-off signal that jointly controls, united controller just with the speed of automobile and acceleration/accel as input parameter, suitably regulate the output torque of current vortex retarder, make the speed of automobile keep stable, thereby reach double mode braking, improve the purpose of ride safety of automobile performance.
Above-described retarder control method, owing to consider multiple factor, system is comparatively complicated, functional reliability and stability still remain to be tested by practice.With regard to the former two, the foundation brakes of brake system and current vortex retarder are carried out independent control, and also there are the following problems: 1, each device of brake system all needs chaufeur to carry out certain operation, and this operation is different with traditional brake operating pattern usually, except the labour intensity that increases chaufeur, also cause the maloperation in the braking procedure easily; 2, independent operation of each device of brake system is unfavorable in the Motor Vehicle Braking Procedure matching coordinative work each other, causes braking excessively easily---influence travelling comfort, or the braking deficiency---influence traffic safety.
Summary of the invention
At the deficiency of above existing vehicle brake control apparatus, the purpose of this utility model provides a kind of later-model vehicle brake control apparatus.
The purpose of this utility model is achieved by the following technical solution:
A kind of vehicle brake control apparatus, it comprises a brake pedal, one with a brake pedal bonded assembly foundation brakes and a current vortex retarder, this current vortex retarder comprises a current vortex retarder excitation winding, an one current vortex retarder excitation winding working control circuit and a current vortex retarder excitation winding relay, this vehicle brake control apparatus also comprises an angular transducer, the one current vortex retarder excitation winding job order controller that all is electrically connected with angular transducer and current vortex retarder, described angular transducer comprises a rotating shaft and a shell, rotating shaft is fixed on the axle of described brake pedal, the shell coaxial package is in described rotating shaft and be fixed on brake pedal, be free-running fit between shell and the rotating shaft, can relatively rotate; Be respectively arranged with the angle sensor element on rotating shaft and the shell, angle when relatively rotating in order to measure the two changes, current vortex retarder excitation winding job order controller is a logic control circuit, and it is according to the mode of operation of the braking angle information Control current vortex retarder excitation winding working control circuit of angular transducer transmission.
With respect to prior art, the utlity model has following advantage:
1, gives full play to the effect of current vortex retarder, reduced the wearing and tearing of foundation brakes brake strap and the heat fade of brake efficiency as much as possible.At the problem of " when brake pedal is controlled, the omnidistance parallel running of the original-pack foundation brakes of current vortex retarder and vehicle ", the utility model is divided into two sections of front and back with the braking distance of stretcher.In vehicle ', the frequency that the little braking of intensity occurs is the highest, so in the not too big leading portion of rate of braking, current vortex retarder works alone, does not have the wearing and tearing and the heat-producing problem of foundation brakes of brake strap.
