Description
Technical field
The utility model relates to the accessory system field of car electrical technology, more specifically a kind of car electricity whirlpool
Flow retarder and return shelves suggestion device.
Background technology
Car is in braking procedure at present, in order to improve the braking ability of vehicle, extends the service life of brake shoes, and one
As have provided with electric eddy current retarder as a kind of complemental brake system equipment on vehicle.But during driver's use,
Due to forgetting or not returning in time shelves current vortex retarder can be caused to be constantly in working condition, such as driver is stepping on the gas
Do not exit the handle gear of current vortex retarder during pedal in time, the current vortex retarder will constantly work, and produce system
Dynamic torque, this not only increases the fuel oil oil consumption of vehicle, can also cause the coil persistent fever of current vortex retarder to produce high temperature, gently
The stator of current vortex retarder is then set to burn failure, it is heavy then cause security incident.
Utility model content
The utility model discloses that a kind of car current vortex retarder returns shelves suggestion device, and its main purpose is to overcome
Deficiencies of the prior art and shortcoming, there is provided a kind of special auxiliary returns shelves suggestion device, and it not only can be in time
Remind driver to be returned shelves processing in time to current vortex retarder in use, and use and more facilitate, be automatic,
Eliminate potential safety hazard existing for car.
The technical solution adopted in the utility model is as follows：
A kind of car current vortex retarder returns shelves suggestion device, including control unit, throttle control circuit, GES electricity
Road, the handle gear control circuit of current vortex retarder and the on-vehicle host for producing the prompting sound, described control unit
It is electrically connected by analog control signal interface and the handle gear control circuit, while the control unit passes through CAN
Data communication connection is established with the throttle control circuit, GES circuit respectively；Described control unit also passes through I/O interfaces
It is connected with the on-vehicle host.
Further, the throttle control circuit includes brake pedal position sensor and the second control unit, and described
Two control units are connected by analog signal interface with the brake pedal position sensor, and pass through CAN and the control
Unit processed establishes data communication.
Further, described control unit is the instrument system processor that car body carries.
It is of the present utility model control application method be：
1st, in the case where driver has and returns shelves in time, the operation principle of this suggestion device is：When driver steps on the throttle
Pedal, the handle gear control circuit of current vortex retarder gather gear signal now, and by acquired information transmission extremely
Control unit, if driver returns shelves in time, control unit obtain that handle gear control circuit sends without gear or shelves
The information that position is successively decreased, controller will not export any information to on-vehicle host, and the loudspeaker that on-vehicle host is controlled will not
Send voice message.
2nd, in the case where driver does not return shelves in time, the operation principle of this suggestion device is：When driver steps on oil
Door pedal, the handle gear control circuit of current vortex retarder gathers gear signal now, if driver does not return in time
Shelves, what control unit obtained that handle gear control circuit sends have gear and the unchanged or incremental information of gear, while from CAN
When acquisition GES is greater than 5KM/H in bus, i.e., vehicle is that in the process of moving, control unit is by output information to vehicle-mounted
Main frame, the loudspeaker that on-vehicle host is controlled is set to send voice message（Prompt tone content is such as：Please clawback retarder handle！）, together
When monitors driver in some time, and when not making any reaction, controller will automatically cut off the electricity of handle gear control circuit
Source, the gear of current vortex retarder is set to fail until controller gets accelerator pedal signal disappearance from CAN.
By above-mentioned to description of the present utility model, compared to the prior art, the utility model has the advantage of：
The utility model is simple in construction, novel in design unique, and control unit pair can be realized with effective control connection
The control of current vortex retarder handle gear, not only it can remind driver in use to current vortex retarder in time
Shelves processing is returned in time, and uses and more facilitates, be automatic, eliminates potential safety hazard existing for car.This practicality simultaneously
New to return shelves in time by voice message driver before the gear of cut-out current vortex retarder, the theory that it is designed is more
Ground hommization, improve the product quality of car.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is theory diagram of the present utility model.
Embodiment
Illustrate with reference to the accompanying drawings further to illustrate specific embodiment of the present utility model.
