The utility model overcomes the technological scheme that its technical problem adopts:
Under this electric-control motor car, throttle determines rotating speed diverter switch control gear, comprise Engine ECU, vehicle body central computer, be connected to power take-off cylinder by gas circuit and be electrically connected on the power take-off solenoid valve of vehicle body central computer, be arranged at the power take-off location switch of power take-off cylinder head, multistate switch and be electrically connected on the power take-off valve of vehicle body central computer, 1 pin of described multistate switch is electrically connected on vehicle power supply, its 6 pin ground connection, its 3 pin is connected to 24V power supply, its 2 pin and 5 pin are electrically connected on Engine ECU, described power take-off location switch one end is electrically connected on vehicle 24V power supply, its the other end is electrically connected on coil-end and the Engine ECU of relay respectively, contact switch end one end of described relay is connected to vehicle body central computer, its the other end ground connection.
In order to show power take-off valve state, also comprise and being arranged in order to show the combination instrument of power take-off to bit sign in operator cabin, described combination instrument is connected to vehicle body central computer by CAN communication line.
The beneficial effects of the utility model are: using the diverter switch of power take-off location switch as throttle under conventional throttle and car, eliminate this operating process of manual operation throw over switch, simplify operating habit, people can be avoided to be misoperation throw over switch simultaneously, stop potential safety hazard.By regulating the gear of multistate switch that motor can be made to switch between multiple fixed rotating speed, and rotating speed control accuracy is high, operates also fairly simple, avoids dress load cisco unity malfunction, has stopped potential safety hazard.

Embodiment
Be described further below in conjunction with accompanying drawing 1 pair of the utility model.
Under this electric-control motor car, throttle determines rotating speed diverter switch control gear, comprise Engine ECU 2, vehicle body central computer 7, be connected to power take-off cylinder by gas circuit and be electrically connected on the power take-off solenoid valve 6 of vehicle body central computer 7, be arranged at the power take-off location switch 3 of power take-off cylinder head, multistate switch 1 and be electrically connected on the power take-off valve 5 of vehicle body central computer 7, 1 pin of multistate switch 1 is electrically connected on vehicle power supply, its 6 pin ground connection, its 3 pin is connected to 24V power supply, its 2 pin and 5 pin are electrically connected on Engine ECU 2, power take-off location switch 3 one end is electrically connected on vehicle 24V power supply, its the other end is electrically connected on coil-end and the Engine ECU 2 of relay 4 respectively, contact switch end one end of relay 4 is connected to vehicle body central computer 7, its the other end ground connection.After pressing power take-off valve 5, after vehicle body central computer 7 receives the closed low control signal of power take-off valve 5, vehicle body central computer 7 meeting output power power supply is to power take-off solenoid valve 6, power take-off solenoid valve 6 conducting, 0.7---power take-off cylinder top puts in place by 0.8MPa air pressure, now power take-off location switch 3 closes, 24V power supply passes through power take-off location switch 3 one tunnel to relay 4, make the coil-end conducting of relay 4, the contact switch end of attracting electric relay 4, now vehicle body central computer 7 can receive the low control signal of relay 4 contact switch end adhesive, and be sent to combination instrument 9 by CAN communication line 8, at its display screen display power take-off to bit sign.24V power supply exports high control signal to Engine ECU 2 by another road of power take-off location switch 3, and after Engine ECU 2 receives this height control signal, throttle is just converted to Throttle Opening Control under car by conventional throttle control, and now conventional throttle control is no longer worked.2 pin of multistate switch 1 are connected with the 5V power supply output pin of throttle under the car of Engine ECU 2, and 5 pin of multistate switch 1 are connected with the signal input pin of throttle under the car of Engine ECU 2.Multistate switch 1 is inner is distributed by different resistances, can export different voltage signals to Engine ECU 2, and each gear output voltage drops within each subregion of Engine ECU 2 control program program (P file) at many gears.By rotating multistate switch 1 to the gear needed, ECU 2 receives the magnitude of voltage that multistate switch 1 current gear exports, and the MAP according to demarcating makes the engine speed short time reach and is fixed on certain tachometer value.Rotating multistate switch 1 to different gear can make motor switch between multiple fixed rotating speed, meets conversion requirements vehicle filling load different rotating speeds when multiple continuous working conditions operation, and has different signaling lamps to light in different gear multistate switch.Using the diverter switch of power take-off location switch 3 as throttle under conventional throttle and car, eliminate this operating process of manual operation throw over switch, simplify operating habit, people can be avoided to be misoperation throw over switch simultaneously, stop potential safety hazard.By regulating the gear of multistate switch 1 that motor can be made to switch between multiple fixed rotating speed, and rotating speed control accuracy is high, operates also fairly simple, avoids dress load cisco unity malfunction, has stopped potential safety hazard.
Also comprise and being arranged in order to show the combination instrument 9 of power take-off to bit sign in operator cabin, combination instrument 9 is connected to vehicle body central computer 7 by CAN communication line 8.After the closed low control signal receiving power take-off valve 5 and relay 4 contact switch, vehicle body central computer 7 utilizes CAN communication line 8 to be sent to combination instrument 9 to show power take-off to bit sign, facilitates the personnel in operator cabin whether to understand power take-off in time in work.
