Abstract

PURPOSE:To finely and appropriately carry out drive control by controlling a driven member rotatably installed on a vehicle in such a way that the driven member is rotated at a constant speed in a middle or low speed range during normal mode operation while being rotated arbitrarily up to a high speed during high speed mode operation. CONSTITUTION:An onboard driven member such as a mixer drum 2 on a concrete mixer truck or the like is driven by a hydraulic motor M which is controlled by a hydraulic pump P driven by a running engine E. The hydraulic pump P is remote-controlled by actuators 4 inside and outside of the truck. In this arrangement, a data processor 12 is installed on the truck. The data processor receives detection signals from rotational speed sensors 13, 15 for the mixer drum 2 and the running engine E, and delivers control signals to a servo-valve SV for the hydraulic pump P and an accelerator drive section 14 for the running engine E.

To explain the operation procedure in detail, the increase, deceleration, and accelerator operations of the reversible variable field 14 hydraulic pump were performed individually manually, but concrete mixer trucks generally use a diesel engine as the power source. Due to the characteristics of a day cell engine, it is difficult to finely adjust the increase and deceleration.
In particular, if the speed exceeds 800 to 9 QQ rpm, the speed will rise, so the five workers increased the speed to some extent only by feeling, and controlled the operation by inching the increase and deceleration of the reversible variable displacement hydraulic pump. However, according to these operating instructions, the engine would speed up more than necessary, causing loud noise and wasting fuel, and the mixer drum rotation was also unstable.This problem was resolved. In order to do this, the applicant previously proposed a system that controlled both the hydraulic pump and the driving engine to keep the drum rotation constant (Japanese Patent Publication No. 62-26930), but even with microcomputer control, the engine rotation was unstable. Since it is very difficult to precisely control the number of rotations of the mixer drum, it is necessary to apply the same amount once for all types of use of concrete mixer trucks.When finely adjusting the rotation speed of the mixer drum, such as when adding, mixing, and discharging fresh concrete, This simplifies the adjustment of engine speed and deceleration depending on the person, and in cases where the mixer drum rotational speed does not need to be adjusted much, such as during cleaning work after discharging fresh concrete.

Further, in detail, when the drum rotation speed set by the external operation device is low speed range NL + 3rd or higher, the accelerator drive unit 14 selects the information processing device according to the operation signal.
A low speed control signal is sent from I12, and the engine speed is set to idling rotation (400 to 500 rpm).The actual engine speed is detected by the speed sensor I5 and fed back to the information processing device 12 as a rotation signal.This feedback The engine speed is maintained at idling speed by the control, and a control signal is sent from the information processing device ff 12 to the servo valve SV in the low speed range N, according to the operating amount of the operating knob 10 to the external operating device 4. , mixer drum 2 is also feedback controlled,
Regardless of the size of the zero hydraulic load, the desired drum rotation speed can be obtained and the drum rotates at a constant rate.

(1) A driven body rotatably mounted on a vehicle, a drive device for rotating the driven body forward, reverse, increasing, and decelerating, and a driving engine for increasing and decelerating the driven body. A drive device is provided, and an information processing device is provided which receives an operation signal from the operation section and outputs a control signal for the drive device or the drive device for the driving engine. The drive device and the driving device of the driving engine are feedback-controlled by the control signal of the information processing device and the feedback operation signal, and the driven body is rotated at a constant speed at medium and low speeds.On the other hand, when the high speed mode is operated by the operation unit, the driving device is rotated at a constant speed. The driving engine is rotated at high speed by the engine drive device, and the drive device is controlled in response to operation signals for forward, reverse, increase, and deceleration rotation, and the driven body is arbitrarily rotated up to high speed. A drive control operation device for a driven body mounted on a vehicle.
