摘要： A system for controlling engine speed for a vehicle such as a fork-lift. The system has an accelerator pedal for controlling an engine speed, and a control lever for controlling the direction of movement of the vehicle, or the system is provided with a seesaw type accelerator pedal for controlling the engine speed and the direction of movement of the vehicle.An EXNOR gate is provided for detecting deceleration of the engine while the accelerator pedal is depressed. When deceleration is detected, the throttle valve is returned to an engine idling position or the supply of fuel is cut. Thus, an effective engine braking can be obtained when the direction of movement of the vehicle is changed while the accelerator pedal is depressed.A window comparator is provided for detecting the area near the end of deceleration, so that the engine speed is increased prior to the commencement of acceleration.

摘要： This invention relates to a cargo-handling vehicle equipped with a cargo-handling apparatus and having a single power plant adapted to commonly drive a hydraulic pump for driving and a hydraulic pump for cargo-handling. A driving command signal in the form of an analog or digital electric signal output from a driving operation device in response to the operated amount thereof is output to first conversion means. The first conversion means converts the driving command signal or the operated amount of the driving operation device to power plant revolution data for driving which is determined by the preset function, and then outputs the data to selection means. A cargo-handling command signal in the form of an analog or digital electric signal output from a cargo-handling operation device in response to the operated amount thereof is output to second conversion means. The second conversion means converts the cargo-handling command signal or the operated amount of the cargo-handling operation device to power plant revolution data for cargo-handling which is determined by the preset function, and then outputs the data to the selection means. The selection means selects at least one of the data and then outputs the selected data to control means for regulating the speed of the power plant. The control means regulates the power plant speed in accordance with the input data.

摘要： A control device for use in a cargo handling vehicle in which a single power plant provides both the vehicle drive and the power to the cargo handling device has a continuously variable transmission. The cargo handling device is actuated by means of a hydraulic pump. Whether or not the cargo handling device is in operation the operator need not adjust the degree of depression of a drive pedal to maintain constant vehicle speed because automatic compensation means are provided for that purpose. The demands upon the vehicle operator are accordingly reduced.

摘要： A forward/reverse drive controller for controlling a vehicle, in which the output of an engine is transmitted through a clutch to an automatic transmission, in which the running direction of the vehicle is changed rapidly and alternately in opposite directions. The controller utilizes a clutch controlling actuator for the variable control of the working condition of the clutch between an engaged state and a disengaged state; a speed change actuator provided in the automatic transmission to shift the automatic transmission; a running speed sensor for detecting the running speed of the vehicle; a forward/reverse shift control lever which is shifted manually to three drive positions, a forward/reverse gear position detector; a braking control unit which applies a braking force when a forward/reverse gear position detector detects the shift of the forward/reverse shift control lever; a decision unit which decides, on the basis of the result of detection of the running speed of the vehicle, whether or not the running speed of the vehicle has been reduced to a predetermined running speed; and a shifting operation control unit which provides a command for shifting the automatic transmission to the predetermined running speed.
