摘要： PURPOSE: To eliminate danger of damaging a drive train by predicting generation of an overspeed condition as a function of speed signals, and adjusting the displacement of a hydraulic motor in accordance with prediction of the overspeed condition. CONSTITUTION: The control means 116 of an overspeed control device 102 reads a mode switch 118, and adjusts the displacement of a hydraulic motor 108 accordingly. When the mode switch 118 is at a low speed position, the control means 116 actuates in a low speed mode, and sets the displacement of the hydraulic motor 108 at the maximum. When the mode switch 118 is at a high speed position, the control means 116 actuates in a high speed mode, and adjusts the displacement of the hydraulic motor 108 both for the low speed and the high speed of the hydraulic motor 108. When a motor speed is increased to a specified value, an overspeed condition is detected. As the overspeed condition is detected, the control means 116 adjusts the motor displacement from the minimum to a specified ratio of the maximum.

摘要： PURPOSE:To improve running feeling during shifting from a running condition to a cargo handling condition by offsetting target vehicle speed for correcting based on an offset amount obtained from difference between vehicle speed and target vehicle speed during cargo handling and running. CONSTITUTION:An engine 1 drives a hydraulic pump 92 for cargo handling which supplies operation oil to a hydraulic cylinder 91 for driving a cargo handling member 90, and a variable pump/motor 2 which variably drives a driving wheel 7. By varying a discharge volume of the pump/motor 2 by means of transmission ratio adjusting members 14, 32, speed of vehicle is controlled to be a target value. In this case, vehicle speed and target vehicle speed are calculated by means of a calculation means 62 based on the detection results of a vehicle speed detection means 56 and an accelerator opening detection means 42. During cargo handling and running, difference between the vehicle speed and the target vehicle speed is obtained, and the resultant difference is set as an offset amount. The target vehicle speed is offset based on the offset amount, and the corrected target vehicle speed is calculated.

摘要： PURPOSE:To hold down pitching to the minimum by obtaining a correction factor of a speed change ratio of a continuously variable transmission according to the operating condition of a brake device special for a driven wheel to correct the target speed change ratio in a motor cycle. CONSTITUTION:Calculating means 201 for the target speed change ratio of a speed change ratio control device 200 obtain a basic target speed change ratio of a continuously variable transmission T from information of detection means for detecting the normal running condition. A detection signal of the first brake sensor Sg is input to calculating means 202, the calculating means obtains a corresponding correction factor according to the operating condition of a brake device special for a driven wheel, and the target speed change ratio is corrected by correction means 203. A detection signal of the second brake sensor Sd is input to correction factor calculating means 202 to obtain a correction factor considering control input of a brake device special for a driving wheel as well as that of the brake device special for a driven wheel. Thus, pitching can be held down to the minimum.

摘要： PURPOSE:To prevent hunting during automatic constant speed running by correcting the target engine revolving speed or target gear ratio on a continuous transmission in accordance with the result from comparison of the actual car speed with the set car speed in automatic constant speed running, and controlling the continuous transmission with the value after correction. CONSTITUTION:An auto cruise control means 304 controls a throttle valve 303 through a drive means 302 so that auto cruise is made when an auto cruise setting with 301 is turned on. A DELTAv calculating means 312 subtracts the actual car speed v given by a car speed sensor Se from the car speed when the auto cruise is set, and the DELTAv is calculated. The correction term Ncauto corresponding to DELTAv is read out of an Ncauto table 313. An Neset calculating means 314 calculates the target revolving speed Neset on the basis of the revolving speed Nemap read out of an Memap map 311, and a feedback control means 315 controls a motor 86, which is to alter the gear ratio of the continuous transmission so that the actual revolving speed Nc becomes identical to the revolving speed Ncsct.

摘要： PURPOSE:To have the car control responded immediately according to a driver's will by correcting either value of an aimed speed change ratio or of an aimed engine speed set from an engine parameter, according to an estimated engine output. CONSTITUTION:An aimed speed change ratio R being read from a storage means 304, based on engine speed, the negative pressure in an inlet pipe, throttle opening obtained at sensors 204, 206, 207, along with a feed-back signal of a speed change ratio detecting sensor 128, a feed-back control means 306 executes control so as to materialize the aimed speed change ratio R by having a swash plate tilt angle of a hydraulic motor altered via a motor 86. At this time, engine output is estimated from data of detected air pressure, or from the increased amount of acceleration, change in setting of running mode, and so on by an engine output estimating means 601, and the additive amount of speed change ratio corresponding to this is read from a storage means 602, and the aimed speed range ratio R is corrected at an addition means 305. In this way, the running of a car can be properly carried out based on the will of a driver.

摘要： PURPOSE:To prevent the occurrence of a speed-change shock in a static hydraulic speed change gear in which a variable displacement hydraulic pump is combined with a variable displacement hydraulic motor by continuously varying the inclinedly rotating angle of the hydraulic motor by taking some time. CONSTITUTION:The driving force of an engine 1 is transmitted to right and left sprockets 10, 11 via hydraulic pumps 3, 4 and hydraulic motors 6, 7. A control circuit 16 duty-ratio controls magnetic proportional control valves 12, 13 based on the step-in quantity of an accelerator pedal 31 and the rotating angle of a steering wheel 32 which are detected by potentiometers 14, 15 and an input engine speed from a rotary pickup 5, to change the inclinedly rotating angle of the hydraulic pumps 3, 4. Also, as a speed range H/L changeover switch 17 is set to the a side, a control current to magnetic proportional valves 18, 19 is gradually increased causing hydraulic motors 6, 7 to be on a high vehicle speed side with the minimum inclinedly rotating angle, whereas, as the switch 17 is set to the L side, the control current is gradually reduced causing the motors 6, 7 to be on a low vehicle speed side with the maximum inclinedly rotating angle. Thereby, the occurrence of a speed-change shock can be avoided.
