Below with reference to the accompanying drawings the shift control method of the electronlmobil of the band AMT change speed gear box according to the embodiment of the present invention is described in detail.
As Figure 2-3, according to the shift control method of the electronlmobil of the band AMT change speed gear box of the embodiment of the present invention, the AMT gearbox control that electronlmobil comprises entire car controller and is connected with entire car controller.
Specifically, described shift control method comprises the following steps:
A: described entire car controller judges whether to receive Acceleration Signal.
B: when described entire car controller does not receive Acceleration Signal, then described entire car controller judges whether to receive speed-slackening signal further.
C: when described entire car controller receives speed-slackening signal, then described entire car controller does not respond the gearshift request of described AMT gearbox control and keeps current gear until the speed of a motor vehicle reduces to the first preset vehicle speed.Otherwise described entire car controller responds the gearshift request of described AMT gearbox control and makes gear decline successively until the speed of a motor vehicle reduces to the first preset vehicle speed according to vehicle speed signal.
According to the shift control method of the electronlmobil of the band AMT change speed gear box of the embodiment of the present invention, when chaufeur needs car retardation, chaufeur is stepped on brake pedal and is carried out forced brake, or does not carry out forced brake (vehicle carries out slow deceleration) while release the gas pedal.In braking procedure, when chaufeur carries out forced brake, entire car controller does not allow AMT gearbox control to shift gears, and carries out pressure keep gear.When chaufeur unclamps bend the throttle, when vehicle carries out slow deceleration, AMT gearbox control can be shifted gears.Ensure traffic safety with this, promote energy regenerating ratio simultaneously, also can reach the effect increasing travelled distance.
That is, setting motor speed is when 6000rpm-3000rpm, and motor can carry out Brake energy recovery.In forced brake process, AMT change speed gear box is not shifted gears, and change speed gear box speed ratio keeps definite value, and along with the decline of the speed of a motor vehicle, motor speed drops to below 3000rpm rapidly, and Brake energy recovery process is shorter.And in slow deceleration process, AMT change speed gear box is shifted gears, converter speed ratio promotes successively, although now the speed of a motor vehicle declines, but motor speed can maintain motor the long period can carry out within the scope of energy regenerating, this adds the process of energy regenerating with regard to actv., can increase Vehicle-Miles of Travel further.
According to one embodiment of present invention, the shift control method of the electronlmobil of described band AMT change speed gear box also comprises:
D: when described entire car controller receives Acceleration Signal, described entire car controller responds the gearshift request of described AMT gearbox control and makes gear increase successively until the speed of a motor vehicle is upgraded to the second preset vehicle speed according to vehicle speed signal.Thus, in the accelerator of electronlmobil, do not affect AMT change speed gear box and shift gears according to vehicle speed signal.
Advantageously, according to some embodiments of the present invention, described gear is third gear, i.e. I shelves as shown in Figure 3, and II keeps off, III shelves.Here it should be noted that, accompanying drawing 3 illustrate only electronlmobil and has three gears, but be with the shift control method of the electronlmobil of AMT change speed gear box to be not limited only to be applied in the electronlmobil only with three gears according to an embodiment of the invention, this is understandable for the person of ordinary skill of the art.
Advantageously, according to an example of the present invention, described first predetermined speed is 0, and namely electronlmobil is in the state of stopping.
Advantageously, according to a concrete example of the present invention, described Acceleration Signal is provided by acceleration pedal.
Advantageously, according to examples more of the present invention, described forced brake signal is provided by brake pedal.
Below with reference to the accompanying drawings 3 sketch to adopt and carry out the process of shifting gears according to the shift control method of the electronlmobil of band AMT change speed gear box according to the present invention.
First it should be noted that, in Brake energy recovery process, entire car controller (VMS) and AMT gearbox control (TCU) accurately can complete information interaction, control with the gear realized in this process.Gear is for third gear.
(1) with reference to the t0 in figure 3---t1 process, step on gradually when chaufeur will speed up pedal and reach 100%, namely in accelerator, VMS responds TCU gearshift and asks and allow gearshift, TCU shifts gears according to shifttable according to Acceleration Signal and vehicle speed signal, gear is by I shelves, and rise to III shelves successively, vehicle accelerates to maximum speed gradually.
(2) when t1, vehicle reaches maximum speed, and gear is III shelves.Now, chaufeur gradually release the gas pedal, until be totally released, steps on brake pedal, carries out forced brake.After VMS receives forced brake signal, no longer respond the gearshift request of TCU, and carry out gear maintenance, until the speed of a motor vehicle reduces to 0, t2 moment gear reduce to 1 grade.
(3) t1 process is similar for t3---process of t4 and t0---, the speed of a motor vehicle is increased to maximum speed gradually, and VMS responds TCU gearshift request and allows gearshift, and TCU shifts gears according to shift table according to Acceleration Signal and vehicle speed signal, gear constantly rises, and vehicle accelerates to maximum speed gradually.Maximum speed reached in the t4 moment.
(4) when t4, vehicle reaches maximum speed, and gear is 3 grades.Release the gas pedal gradually, does not now step on brake pedal, and vehicle slides slowly, VMS responds TCU gearshift request, and allows gearshift, and TCU shifts gears according to shift table according to vehicle speed signal, gear declines successively, and it is 1 grade that the speed of a motor vehicle reduces to zero, t5 moment gear gradually.
According to the shift control method of the electronlmobil of the band AMT change speed gear box of the embodiment of the present invention, when chaufeur needs car retardation, chaufeur is stepped on brake pedal and is carried out forced brake, or does not carry out forced brake (vehicle carries out slow deceleration) while release the gas pedal.In braking procedure, when chaufeur carries out forced brake, entire car controller does not allow AMT controller to shift gears, and carries out pressure keep gear; When chaufeur unclamps bend the throttle, when vehicle carries out slow deceleration, AMT controller can be shifted gears.Ensure traffic safety with this, promote energy regenerating ratio simultaneously, also can reach the effect increasing travelled distance.
