Specific embodiment
Refer to Fig. 4, the control system of double clutch gearboxes of the application includes a double clutch gearbox body and two
Individual structure identical controller.One of controller is master controller, and another controller is from controller.
Described pair of clutch gearbox body includes passing for the rotating speed gathering engine speed and output shaft of gear-box rotating speed
Sensor group, it is used for gathering the odd number shelves sensor group of odd number shelves input shaft rotating speed and each odd number shelves synchronized state, for adopting
Collection even gear input shaft rotating speed and each even gear synchronized state even gear sensor group, be used for control odd number shelves clutch
With the odd number shelves actuator group of each odd number shelves synchronized, be used for controlling even gear clutch and the idol of each even gear synchronized
Several grades of actuator groups.For example, speed probe group includes engine speed sensor and OSS, and odd number shelves pass
Sensor group includes odd number shelves input shaft rotating speed sensor and odd number shelves synchronizer displacement sensor, and even gear sensor group includes idol
Several grades of input shaft rotating speed sensors and even gear synchronizer displacement sensor, odd number shelves actuator group includes multiple odd number shelves electromagnetism
Valve controls odd number shelves clutch and each odd number shelves synchronized respectively, and even gear actuator includes multiple even gear magnetic valves respectively
Control even gear clutch and each even gear synchronized.Described odd number shelves synchronizer displacement sensor have one or more, point
Do not gather each odd number shelves synchronized state.Described even gear synchronizer displacement sensor also has one or more, gathers respectively
Each even gear synchronized state.
Each controller all comprise one piece of control chip, communication unit, power module, input module,
One drive module.This shows that two controllers are single chip architecture.Pass through vehicle between the communication unit of two controllers
Bus (such as can bus) mutually communicates.The power module of two controllers is respectively respective controller and powers.Two controls
The input module of device connects respectively and receives odd number shelves sensor group, the signal of even gear sensor group.Master controller in Fig. 4

Signal.The drive module connecting the controller of odd number shelves sensor group connects and controls odd number shelves actuator group, connects even number
The drive module of the controller of shelves sensor group connects and controls even gear actuator group.
The implementation method of the control system of double clutch gearboxes of the application is:
During normal work, master controller receives connected sensor, and (speed probe group and odd number shelves or even gear pass
One of sensor group) signal that gathers, and be responsible for calculating the parameters such as target gear, electromagnetic valve current.From the controller also company of reception
Signal that the sensor the two of even gear sensor group (odd number shelves or) connecing gathers simultaneously is sent to master controller by communication module.
Do not carry out evaluation work from controller, simply accept the result of calculation of master controller.Pass through high-speed bus between two controllers
Both-way communication.Each controller controls the actuator (magnetic valve) each being connected respectively.Due to two controllers simultaneously now
Work, all actuators of double clutch gearboxes are all controlled, you can to realize whole gears of double clutch gearboxes.
Each controller itself has diagnostic function.When detecting itself and breaking down from controller, from controller
All actuators of its connection will be closed, and fault message is sent to master controller.Master controller can also be independently by
Communication diagnostic function judges to break down from controller, and such as two controller agreements are communicated according to certain intervals, if
The timing communication that one controller continuous several times do not receive another controller then independent judges that this another controller breaks down.When
Master controller is known and is broken down from controller, and master controller masks in target gear calculating logic to be responsible for from controller
Corresponding gear.Now double clutch gearboxes still can cut, by master controller independent control, the corresponding shelves that master controller is responsible for
Position.
When master controller detects itself and breaks down, master controller will cut out all actuators of its connection, and will
Fault message is sent to from controller.Can also judge that event in master controller independently by Communication diagnostic function from controller
Barrier.When knowing that master controller breaks down from controller, will take over target gear, electromagnetic valve current etc. from controller and calculate work
Make.The signal of speed probe group can be gathered due to only having master controller, when master controller breaks down, first-selected main control
The signal that speed probe group gathers is sent to from controller by device by communication module, if the fault impact of master controller should
Sending operation so can also be by bus by engine controller acquisition engine speed information, by abs control from controller
It is output shaft of gear-box rotary speed information that device obtains speed.Also target gear calculating logic, mask master controller from controller
Responsible corresponding gear.Now double clutch gearboxes still can be responsible for from controller by cutting from controller independent control
Corresponding gear.
Because two controllers are each responsible for odd gear, even gear, therefore when any controller breaks down, double
Clutch gearbox vehicle only has about half gear and cannot realize, and is capable of remaining about half gear.This be enough to make double clutches
Gearbox vehicle is adhered to driving to safety place or is accepted maintenance, and is not to run out of steam suddenly, thus substantially increasing peace
Full reliability.
Implementation above method all assumes that the controller breaking down can it is connected with normal switching-off all actuators.As
The fault that fruit controller occurs seriously arrives it and cannot close connected actuator, then double clutch gearboxes can be led to be stuck in and work as
Front gear.Now another normal controller can integrated communication diagnostic function, gearratio (being calculated in real time based on each rotating speed)
Judge this catastrophe failure, and close all actuators that this normal controller is connected, to avoid damaging double clutches changes
Fast case.Now, because double clutch gearboxes can not pluck gear, driver can only be strong by losing throttle, the mode such as touch on the brake, pull the hand brake
Vehicle deceleration processed, until engine misses, vehicle stop completely.
