Abstract

The invention discloses a vehicle braking method. When a brake paddle is stepped down, a position sensing device connected with the brake paddle sends a position signal to an eddy current retarder controller, and thus an eddy current retarder works; and when the brake paddle is continuously stepped down, the service brake of the vehicle works. According to the vehicle braking method, the operation intensity of a driver is lowered, and the working times of the service brake are reduced, and the service life of the easily-damaged parts of the braking system is prolonged so as to improve the safety of vehicle driving.

Description

A kind of vehicle braking method
Technical field
The present invention relates to vehicle brake technology, especially relate to a kind of vehicle brake technology that adopts current vortex retarder.
Background technology
Existing a lot of vehicle provided with electric eddy current retarders, carry out auxiliary braking by current vortex retarder.The mechanical electric apparatus unit of current vortex retarder is controlled by control unit, this control unit receives the operating switch information of vehicle driver with the hand input, perhaps receive the footbrake pedal information of chaufeur, the air pressure produced by master cylinder is opened pressure switch, controls the break-make of stator coil according to this switch.No matter be to spoil brake pedal manipulation with manual manipulation or with pin, all exist some drawbacks, such as with hand, chaufeur just can not the two hand-tight bearing circle of holding, increase labour intensity etc.By the baroswitch foot control, can not realize that again retarder works alone in main brake in advance, can not reduce the friction of main brake sheet.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above defect, proposes a kind of braking method of vehicle, reduces driver's operation, reduces the work times of main brake.
Technical scheme of the present invention is, a kind of vehicle braking method, brake process is divided into first brake process and the second brake process, in the first brake process, after stepping on brake pedal, the position induction device be connected with brake pedal sends position signal to controller of current vortex retarder, makes current vortex retarder work; In the second brake process, after continuing to step on brake pedal, the work of vehicle main brake.
The present invention is compared with the prior art had beneficial effect: when chaufeur gently touches on the brake pedal with pin, the location sensitive switch be arranged in brake pedal idle travel scope sends a signal to buffer controller, current vortex retarder is in advance in foundation brakes work, car retardation; If chaufeur is no longer firmly adopted pedal, main brake is not worked, only retarder work.Not only meet existing driving habit, reduce the manipulation strength of chaufeur, and reduced the work times of main brake, extended the life-span of brake system consumable accessory, thereby improve the safety of Vehicle Driving Cycle.
The accompanying drawing explanation
The brake device structure schematic diagram that Fig. 1 is the specific embodiment.
The specific embodiment
A kind of vehicle brake device as shown in Figure 1, comprise brake pedal 1, main brake device 2, position induction device, current vortex retarder 5, and position induction device comprises position converyer 3, micro-switch 4.Position converyer 3 is connected with brake pedal 1, and the displacement of brake pedal 4 is passed to micro-switch 4, and micro-switch 4 changes position signal into electric signal transmission again to current vortex retarder 5.Position induction device can receive the idle travel displacement of brake pedal 1, and said idle travel refers to that at brake pedal, in the trip, the main brake device is failed to receive brake signal and worked.
The braking method of above-mentioned vehicle is, after chaufeur is gently stepped on brake pedal 1, micro-switch is sent out 4 and gone out the controller of signal to current vortex retarder 5, and the controller of electric vortex buffering 5 is connected first group of excitation coil, first group of excitation coil energising work, car retardation; If chaufeur no longer continues firmly push down on the pedal 1, main brake 2 is not worked, only first group of excitation coil work of current vortex retarder; If chaufeur keeps this position to surpass setting-up time as 0.25 second or 0.5 second, the controller of electric vortex buffering 5 is connected again second group of excitation coil, and second group of excitation coil energising work, add hard braking simultaneously.The controller of electric vortex buffering 5 can pass through software or a plurality of gears of hardware setting, as four gears, according to chaufeur, keeps the time of idle travel normal danger to connect successively 1~4 group of excitation coil, increases the weight of braking action power.Can control well braking strength like this.
When continuing to step on brake pedal 1, after surpassing the brake pedal idle travel, 2 brakings of vehicle main brake.Like this brake process is divided into to two parts, the brake little to intensity just can meet the demands by retarder, extended the life-span of main brake, improved the safety of vehicle.
Above content is in conjunction with concrete embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.

Claims (1)

1. a vehicle braking method, it is characterized in that, brake process is divided into first brake process and the second brake process, in the first brake process, after stepping on brake pedal, the position induction device be connected with brake pedal sends position signal to controller of current vortex retarder, makes current vortex retarder work; In the second brake process, after continuing to step on brake pedal, the work of vehicle main brake; In the first brake process, chaufeur depresses brake pedal and keeps this position to surpass setting-up time, and current vortex retarder is connected the excitation coil of a plurality of current vortex retarders successively.
