On, gas pedal 5 connect EFI engine 9, power supply 8 connect controller 6, display 3, EFI engine 9, brake pedal valve 4,
Gas pedal 5, cruise add, cruise subtracts point driving switch 2 and velocity sensor 7.
In order to further illustrate above-described embodiment, controller 6 uses Rexroth RC6-9 type controller, the detection touching of controller 6
The signal of switch 1, brake pedal valve 4, display 3 and velocity sensor 7 is sent out, the revolving speed of EFI engine 9 is controlled.
In order to further illustrate above-described embodiment, trigger switch 1 is Schneider ZB2BK-125 trigger switch, trigger switch 1
For inching button.
In order to further illustrate above-described embodiment, EFI engine 9 is WP6 type EFI engine.
In order to further illustrate above-described embodiment, cruise plus, cruise subtract point driving switch 2 be the cruise of JK932-057 type plus, patrol
Boat subtracts point driving switch.
In order to further illustrate above-described embodiment, brake pedal valve 4 is MICO06-466-106S type brake pedal valve, system
Dynamic treadle valve 4 has pressure switch.
In order to further illustrate above-described embodiment, gas pedal 5 is 406788 type gas pedal of WILLIAMS-DARLING Ton.
In order to further illustrate above-described embodiment, power supply 8 is Wa Er tower 31-750BMF type power supply.
In order to further illustrate above-described embodiment, display 3 is Rexroth DI3 escope.
The working principle of the present embodiment are as follows: controller 6 is adopted by the speed of travel of the velocity sensor 7 to land leveller
Collection, it is cruising speed that when trigger switch 1 is pressed, controller 6, which records the current speed of travel, and controller 6 passes through velocity sensor
7 can get the current speed of travel, specific calculation formula are as follows:
V=0.06*3.14*R1*N1/ (N2*N3)；Above-mentioned formula is calculation formula in the prior art；
Wherein, N1 is the umber of pulse that engine speed sensor obtains, and N2 is flywheel shell of engine number of gear teeth, and N3 is to drive
Dynamic bridge reduction ratio, R1 are tire on the drive wheels diameter；From the above equation, we can see that N2 and N3 are known definite value, N1 is respectively by velocity pick-up
Device 7 obtains, therefore can get the speed V of driving wheel, and taking V is exactly the current speed of travel, and subsequent controller 6 is by current walking
Speed is compared with cruising speed, and when finding that the speed of travel is greater than cruising speed, controller 6 passes through the electricity with EFI engine 9
The connection of control system ECU reduces the revolving speed of EFI engine 9, and when finding that the speed of travel is less than cruising speed, controller 6 increases
The revolving speed of big EFI engine 9, equipped with cruise plus, cruise subtract point driving switch 2, function is every crawl under cruise operation mode
Cruise once adds, cruise subtracts point driving switch 2, and 9 revolving speed of EFI engine increase accordingly or reduce 50r/min, corresponding traveling speed
Degree is accordingly increased or is reduced.Cruising speed can be arbitrarily controlled according to operating condition and real work situation, until set by reaching
Greatest limit speed.
