The output of described each binary pair connects a LED light.
Described each gear is the moving seesaw-type gear switch that has auto-reset function, and each gear switch connects a LED light; The described moving seesaw-type gear switch that has auto-reset function is to have spring from the wane type switch that resets.
Parking shelves P, the reverse R that is provided with on the chaufeur control panel like this, neutral gear N, low gear D1, high speed gear D2 are for being with the moving seesaw-type gear switch of auto-reset function, each gear switch connects two LED light, be respectively applied for the current switch motion state of indication and current effective range state, the gear switch is the JK993 series switch as MILEAGE.The gear switch signal send entire car controller VMS by the gear shift control circuit, finishes the gear shift action by entire car controller VMS control autoshift actuating unit.
The gear shift control circuit has been realized the gear signal transmitting function, and reverse R and D Drive D1, D2 realize interlock function by the gear shift control circuit.
The mode of button indication is adopted in the operation of the utility model new forms of energy city bus wane type switch gear, and when chaufeur is pressed: key position indicator lamp P_LED1 lights during as Parking shelves P key, and after this P was good for and automatically resets, P_LED1 extinguished; Produce a cooresponding impulse singla simultaneously by the P key, this signal is after the gear shift control circuit is handled, and promptly whether decision operation is effective, as effectively then opening Parking shelves P bonded state indicator lamp P_LED2, otherwise, gear system held previous status.
The principle of work of the utility model new forms of energy city bus wane type switch gear is:
At first, after entire car controller VMS and gear shift control circuit powered on, the acquiescence gear was neutral gear N shelves, opens N shelves status indicator lamp; Entire car controller VMS provides command adapted thereto, if vehicle moves ahead in advance, then (is low gear D1 or high speed gear D2, is referred to as D by D Drive D key, down together), D key position indicator lamp is bright, and N shelves indicator lamp goes out simultaneously, after the D key put in place, the D status lamp lighted, and entire car controller is carried out the D signal; If vehicle is moveed backward in advance, then by reverse R key, action is similar with the D shelves.
The binary pair that utilizes this case to adopt is met the characteristic that the positive rise signal condition is just overturn for D flip-flop trigger end CLK, if current shelves are reverse R shelves, it is invalid then to press D Drive D shelves, and status lamp and gear shift control circuit are all kept original signal R, can only unlock by neutral gear N (or Parking shelves P) key; Its principle of work is referring to the gear shift control circuit of Fig. 2, the non-signal of reverse
Import the 5th with the door 15 input ends, for low level signal is " 0 ", no matter the 5th to accept first joint denial gate 11 with door 15 input ends be D1/D2 through the D Drive D(of the 3rd not gate 13 output) signal is " 1 " or " 0 ", the 5th with the door 15 output be always low level " 0 ", D Drive D shelves signal is by the 3rd binary pair 3 Last status
The signal locking, the shelves of Parking simultaneously P, neutral gear N are low level " 0 " (no actuation of keys) by key input signal, reverse R is low level " 0 " under the button reset mode, no matter which kind of state D Drive D1, D2 are at this moment, the 4th with the door 14 output low levels " 0 ", then the 6th or door 16 outputs all binary pair trigger end CLK end signals are kept low level " 0 ", all binary pairs keep Last status constant, promptly press D Drive D be good for invalid.
If current shelves be D Drive D shelves, then invalid by reverse R shelves, status lamp and gear shift control circuit are all kept original signal D, can only be by neutral gear N(or Parking shelves P) be good for and unlock; Its principle of work is referring to the gear shift control circuit of Fig. 2, and D Drive D is low level " 0 " under the button reset mode, is output as high level " 1 " through first joint denial gate 11, is low level " 0 " behind the 3rd not gate 13, add the 5th with door 15 input ends, no matter make
State why, the 5th with the door 15 output be always low level " 0 " join the 6th or the door 16 input ends, D Drive D is output as low level " 0 " behind second joint denial gate 12 simultaneously, low level " 0 " be linked into the 4th with the door 14 input ends, be " 1 " or " 0 " no matter the 4th accepts backward gear R signal simultaneously with door 14 input ends, the 4th is always with door 14 outputs and joins the 6th or door 16 input ends after the low level " 0 ", the shelves of Parking simultaneously P, neutral gear N button is a reset mode, signal is low level " 0 ", therefore the 6th or door 16 outputs keep low level " 0 ", to keep Last status not constant owing to receive skip signal for all binary pair trigger end CLK end, and it is invalid promptly to be good for by reverse R.
If current shelves are neutral gear N or Parking shelves P, then arbitrarily gear shift is effectively.
More than the explanation in effectively at first refer to button after the corresponding state indicator lamp open, refer to that simultaneously gear shift control circuit corresponding signal send entire car controller VMS, motor corresponding driving mode is effective in the entire car controller VMS control policy, and as neutral gear N shelves, motor torque is made as zero irrelevant with the Das Gaspedal value; D Drive D shelves, then motor steering just is made as changes, the corresponding Automatic Transmission control of the D Drive D that closes relay; Parking shelves P shelves, motor speed are made as zero, the corresponding Automatic Transmission control of the Parking shelves P that closes relay; Reverse R shelves, then motor steering is made as counter-rotating, the corresponding Automatic Transmission control of the reverse of closing R relay.Corresponding indicator lamp and control corresponding relay are kept Last status behind the invalid finger button in the explanation.
It below only is preferred embodiment of the present utility model; be not to be used to limit protection domain of the present utility model; therefore, all any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
