Description
Technical field
The present invention relates to the control methods in automobile assistant braking system, and in particular to Retarder and engine exhaust
The control method of Associated brake.
Background technology
CN201510028857.9 disclose a kind of AMT vehicles based on Retarder constant-speed-cruise control system and
Method.The technical issues of it is solved is to improve vehicle fuel economy under the premise of meeting vehicle power.Its technical solution：
The constant-speed-cruise control method of the AMT vehicles based on Retarder is：(1) instrument sends constant speed to car body controller BCU
Cruise signal, and after vehicle enters cruise state, car body controller BCU preserves the vehicle speed value of setting, and monitors current vehicle speed
Value；The current vehicle speed value is sent to car body controller BCU by ABS in real time；Car body controller BCU to current vehicle speed value with set
Determine vehicle speed value to be compared, if current vehicle speed value is more than setting vehicle speed value, then follow the steps (3), if current vehicle speed value is less than setting
(7) vehicle speed value thens follow the steps, if current vehicle speed value is equal to setting vehicle speed value, then follow the steps (6)；(3) car body controller BCU is logical
Cross transmission TSC1Information controls Retarder work, promotes vehicle deceleration, while controlling engine by TSC1 information to reduce
(4) torque if vehicle is not decelerated to setting value yet, thens follow the steps after Retarder stopping power reaches 100%, no
It thens follow the steps (6)；Can speed be decelerated to setting value after the Retarder stopping power reaches 100%, be primarily to see vehicle
Whether deceleration reaches the deceleration standard of setting, such as 0.15m/s2；(4) car body controller BCU excites engine exhaust system
It is dynamic, so that vehicle is further strengthened stopping power, car body controller BCU monitors current vehicle speed value, if current vehicle speed value is not slowed down yet
To setting vehicle speed value, thens follow the steps (5), if current vehicle speed value is decelerated to setting vehicle speed value, then follow the steps (6)；It is described to start
Can speed be decelerated to setting value after machine exhaust brake is opened, and be primarily to see the deceleration scale whether vehicle deceleration reaches setting
Standard, such as 0.15m/s2；(5) car body controller BCU excites the buzzer warning in instrument；(6) car body controller BCU monitoring is current
Whether cruise state is cancelled, if being cancelled, thens follow the steps (11), no to then follow the steps (2)；Cancel cruise state
Condition be：It steps on the throttle and pedal or brake pedal or exits cruise by meter key；Car body controller BCU according to
Current vehicle speed value, setting vehicle speed value and the calculated required tachometer value for needing engine to reach are to determine whether need to drop
Shelves, if desired downshift, then follow the steps (8), no to then follow the steps (10)；Wherein, the tachometer value needed for engine is by following formula meter
It obtains：ua=0.377*r*n/ig/i0,
Wherein：uaIt is radius of wheel (m) for speed (km/h), r, n is engine speed (rpm), igIt is current for speed changer
Gear speed ratio, i0For speed ratio of main reducer；For specific vehicle, r and i0All it is fixed value, only engine speed and change
Fast device speed ratio is alterable；Assuming that current rotating speed is r1, gear speed ratio is ig1, the engine speed after gear variation is r2, gear
Speed ratio is ig2, then by above formula as it can be seen that working as speed uaConstant, the engine speed after gear variation is r2=r1*ig2/ig1；It is heavy
Work as engine speed above or below this mostly within the scope of 1100~1500rpm in commercial vehicle engine economic speed area
When range, then AMT upshifts or downshift are needed accordingly, to allow engine speed to come back to the section；(8) car body controller BCU
Pass through TC1Information sends shift control command to speed changer TCU；(9) speed changer TCU controls clutch actuating mechanism action, switching
To target gear；(10) car body controller BCU passes through TSC1Information is sent to Engine ECU rotating speed control command, reaches step
(6) the tachometer value of engine needed for rapid (7) calculated, then executes step；(11) car body controller BCU terminates to engine, certainly
The control of dynamic speed changer, Retarder, exits cruise state.Disadvantage is that：1) control method is according only to vehicle
Speed variation is worked by car body controller BCU controls Retarder, exhaust brake, not to the work of execution unit Retarder
State is made a concrete analysis of, it is possible to which Retarder is in abnormal operating state, such as overtemperature.2) always with fluid power when braking
Retarder is preferential, can influence the service life of Retarder and its cooling system.3) it is only limitted to cruise, in addition vehicle body control
Device BCU processed only controls how Retarder, exhaust brake participate in work, does not consider after speed lowers, Retarder,
The problem of how exhaust brake exits braking.
