As shown in fig. 2, fig. 2 is a state machine of the gear shift control, and each control state is analyzed and explained as follows:
(1) shift StandBy (Standby mode)
When the rotating speed of the engine is more than or equal to 500rpm and the vehicle speed is more than 0km/h, the state of the StandBy is entered, if the conditions are not met, the engine is not started or the vehicle is not started, the device does not work, and no key signal is responded.
(2) Shift On (On mode) → Gear Up (upshift mode)
Figure BDA0002766664810000071
Entering Gear Up (upshift mode)
When in Standby mode, pressing the Up-shift key "+", Gear Up will be entered:
Figure BDA0002766664810000085
prompting the engaged gear
After entering Gear Up, the voice module broadcasts a prompt tone to 'please take neutral Gear', and simultaneously limits the torque percentage of the engine to A% through the CAN message (the value of A is set according to the vehicle type and the engine parameter), and then waits for the driver to take the Gear to neutral Gear.
Figure BDA0002766664810000081
Synchronous gearbox shaft speed and engine speed (synchronous speed calculation and control):
when the driver takes the gear into the neutral gear, the rotating speed of the engine is controlled to be B rpm through the CAN message. The rotating speed B needs to be calculated in real time according to the vehicle speed, and the controlled rotating speed is updated in real time, wherein the calculation formula is as described above.
Figure BDA0002766664810000082
Prompting for a gear engagement operation
When the difference between the actual engine speed and the synchronous speed B rpm at the moment is within 100rpm, a warning sound is sent to 'please engage the next gear'.
Figure BDA0002766664810000083
Completing the upshift operation
After the upshift is completed, the control is exited and the Standby mode state is returned.
(3) Shift On (Start mode) → Gear Up Plus (continuous upshift mode)
Gear Up Plus (continuous upshift mode) is used to directly shift to the highest Gear recommended for engagement at the current vehicle speed.
Figure BDA0002766664810000084
Enter Gear Up Plus (continuous upshift mode)
When the state is Standby mode, if a signal of pressing the two Up-shift keys "+" is received, then the state enters into Gear Up Plus (continuous Up-shift mode).
Figure BDA0002766664810000086
Prompting the engaged gear
And (3) sending a prompt sound of 'off neutral gear', limiting the torque percentage of the engine to be C% through a CAN message (the value of C is set according to the vehicle type and the engine parameters), and waiting for the driver to off neutral gear.
The control device and the operation method for the manual transmission gear shifting without stepping on the clutch and without releasing the accelerator can also realize the continuous downshift mode, which is similar to the continuous upshift mode, only needs to continuously press the downshift key twice and is the same as the continuous upshift mode.
When the highest gear which is recommended to be engaged under the current vehicle speed is calculated to be an X gear: substituting the speed ratios of all gears higher than the current gear into the formula to calculate the shaft speed n of the gearbox under the corresponding gear1、n2、n3...nHighest gearTaking the above numerical value as the lower limit N of the gear shifting rotating speedminAnd an upper shift speed limit NmaxThe highest gear in between is used as the gear recommended to be engaged for prompting, wherein NminAnd NmaxIs a value set according to an engine parameter.
