Abstract
The utility model discloses a device for controlling a clutch. The device comprises a vacuum degree sensor, an ECU (Engine Control Unit) and a TCU (Transmission Control Unit), wherein the vacuum degree sensor is connected to the ECU through a hard wire; the ECU and the TCU are connected by a CAN (Controller Area Network) bus.
Description
Technical field
the utility model relates to engine petrol, and relates in particular to the device of control clutch.
Background technology
the existing vehicle that possesses engine petrol machine (supercharging, naturally aspirated) and AT fluid power electric control automatic gear shifting case, when all kinds of mechanical electric apparatus loads of cold start-up or original place reach maximum (for example, original place hangs D shelves, turning on the aircondition and killing turns to), degree of vacuum can be not enough, thereby drag ability is reduced, cause braking stone, easily occur Peril Incident.In prior art, for addressing this problem, be vehicle configuration EVP(electronic vacuum pump), but this will make integral vehicle cost rise, and also the service life of EVP is shorter.
Utility model content
a kind of device of control clutch is disclosed according to an object of the present utility model, comprise vacuum sensor, engine control unit ECU and transmission control unit TCU, wherein, described vacuum sensor is connected to ECU by rigid line, described ECU is connected by CAN bus with described TCU, wherein, described vacuum sensor is arranged on vacuum booster, for gathering the degree of vacuum in vacuum booster, described ECU is configured to receive degree of vacuum from described vacuum sensor, when described degree of vacuum is less than the first predetermined value, to described TCU, send power-transfer clutch and disconnect request, described TCU is configured to disconnect request according to the described power-transfer clutch receiving from described ECU, disconnect the power-transfer clutch of AT change speed gear box.
in one embodiment, described ECU be also configured to can by rigid line connect from Das Gaspedal receive accelerator pedal signal, brake switch from brake pedal receives speed-slackening signal, via CAN bus, receive vehicle speed signal and gear signal, and obtain the status signal of air-conditioning compressor, described ECU is configured to described TCU, to send power-transfer clutch under additional conditions and disconnects request, wherein said additional conditions are that accelerator pedal signal is 1, and speed-slackening signal is 1, vehicle speed signal is less than or equal to the second predetermined value, gear signal is 1 or 7, compressor status signal is 0.
Accompanying drawing explanation
accompanying drawing is only for coordinating specific embodiment explanation the technical solution of the utility model, and is not intended to protection domain of the present utility model to be construed as limiting.
fig. 1 is according to the intention of the device of the control clutch of the utility model embodiment.
The specific embodiment
fig. 1 is according to the intention of the device of the control clutch of the utility model embodiment.As shown in Figure 1, this device, comprise vacuum sensor, engine control unit ECU(ENGNIE CONTROL UNIT) and transmission control unit TCU(TRANSMISSION CONTROL UNIT), wherein, described vacuum sensor is connected to ECU by rigid line, described ECU is connected by CAN bus with described TCU, wherein, described vacuum sensor is arranged on vacuum booster, for gathering the degree of vacuum in vacuum booster, described ECU is configured to receive degree of vacuum from described vacuum sensor, when described degree of vacuum is less than the first predetermined value, to described TCU, send power-transfer clutch and disconnect request, described TCU is configured to disconnect request according to the described power-transfer clutch receiving from described ECU, disconnect the power-transfer clutch of AT change speed gear box.
in one embodiment, described ECU be also configured to can by rigid line connect from Das Gaspedal receive accelerator pedal signal, brake switch from brake pedal receives speed-slackening signal, via CAN bus, receive vehicle speed signal and gear signal, and obtain the status signal of air-conditioning compressor, described ECU is configured to described TCU, to send power-transfer clutch under additional conditions and disconnects request, wherein said additional conditions are that accelerator pedal signal is 1, and speed-slackening signal is 1, vehicle speed signal is less than or equal to the second predetermined value, gear signal is 1 or 7, compressor status signal is 0.
in the above-described embodiments, degree of vacuum can be less than the first predetermined value of for example 350hpa; Accelerator pedal signal is that 1 expression Das Gaspedal aperture signal is 0, and now driving engine is in idling mode; Speed-slackening signal is the state of 1 expression vehicle in driver intention brake; Vehicle speed signal can be less than or equal to the second predetermined value of for example 10km/h; Gear signal be 1 expression gear in 1 grade of state, gear signal is that 7 expression gear signal are in reverse gear state; Compressor status signal is that 0 expression compressor is in off-state.
it will be appreciated by those skilled in the art that, can connect from Das Gaspedal and obtain accelerator pedal signal by rigid line, by rigid line, connect by the brake switch on brake pedal and obtain speed-slackening signal, via CAN bus, obtain vehicle speed signal and gear signal, ECU can directly transfer the status signal of air-conditioning compressor.
by under these conditions, after TCU cut-off clutch because sliding wear resisting moment consumption between the inside pump impeller of tor-con and turbine reduces, thereby reduced the torque consumption of driving engine, reduced throttle opening, therefore can greatly promote degree of vacuum with this, thereby promote drag ability, device of the present utility model can be used EVP, has reduced and has made car cost.
by the description of above embodiment, those skilled in the art can understand, and in the situation that not departing from spirit and scope of the present utility model, can also do various changes and replacement to the specific embodiment of the present utility model.These changes and replacement all drop in the utility model claims limited range.
