Patent number: 9828225Abstract: An apparatus for controlling a load handling device of an industrial vehicle is provided. The load handling device includes a mast assembly and a load handling attachment attached to the mast assembly. The apparatus includes a tilt angle detector that detects a tilt angle of the mast assembly, a controller that regulates a lifting speed of the load handling attachment, and a determination device that determines whether or not the load handling attachment is being lifted off the ground. When the determination device determines that the load handling attachment is being lifted off the ground, the controller permits the load handling attachment to be lifted at a speed faster than the regulated lifting speed.Type: GrantFiled: October 6, 2015Date of Patent: November 28, 2017Assignee: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Yasuhiro Taki, Tadashi Yamada, Takashi Nishiwaki, Junichi Kuwayama, Hidenori Oka, Kimihide Hasegawa, Hiroshi Murata

Patent number: 9731950Abstract: An apparatus for controlling a load handling device of an industrial vehicle includes a lifted height detector that detects a lifted height of the load handling device, a tilt angle detector that detects a tilt angle of the load handling device, a loading pump that pumps hydraulic oil from a hydraulic tank in the industrial vehicle and supplies the hydraulic oil to a lift cylinder and a tilt cylinder, a drive that drives the loading pump, and a controller that controls the flow rate of hydraulic oil supplied to the lift cylinder and the tilt cylinder. When the forward tilt angle of the load handling device is greater than a first regulation tilt angle and a lifted height of the load handling device is higher than a predetermined reference height, the controller regulates the flow rate of hydraulic oil supplied to the lift cylinder.Type: GrantFiled: September 21, 2015Date of Patent: August 15, 2017Assignee: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Tadashi Yamada, Takashi Nishiwaki, Junichi Kuwayama, Hidenori Oka, Kimihide Hasegawa, Hiroshi Murata

Patent number: 7568547Abstract: A drive control apparatus for a forklift. Based on the load state, it is determined whether to limit a maximum vehicle speed and an acceleration/deceleration during traveling of the forklift. Limitation contents regarding the maximum vehicle speed and the acceleration/deceleration is determined based on a determination result of whether to put the limitations. A speed of the engine is adjusted based on the determined limitation contents, thereby controlling driving of the forklift. When the determined limitation contents are changed, an acceleration/deceleration limitation value is selected from a plurality of acceleration/deceleration limitation values according to the pattern of the change of the limitation contents, and drive control related to the acceleration/deceleration is executed to limit the acceleration/deceleration of the forklift by using the selected acceleration/deceleration limitation value.Type: GrantFiled: September 29, 2006Date of Patent: August 4, 2009Assignee: Kabushiki Kaisha Toyota JidoshokkiInventors: Tadashi Yamada, Hidenori Oka, Toshikazu Kamiya, Kimihide Hasegawa, Michihiro Miura, Masayuki Takahashi, Hirokazu Kobayashi

Patent number: 7524268Abstract: A load determining section of a drive control apparatus for forklift determines a load state related to a loading attachment. In a case where a connection determining section determines switching to a connection state, if the load state determined by the load determining section requires that driving of a vehicle body be limited, a disconnection control section forcibly disconnects a transmission of a driving force to a drive wheel. Thus, the forklift is prevented from being started in a state that is likely to make the driving of the forklift unstable.Type: GrantFiled: September 29, 2006Date of Patent: April 28, 2009Assignee: Kabushiki Kaisha Toyota JidoshokkiInventors: Hidenori Oka, Tadashi Yamada, Toshikazu Kamiya, Masayuki Takahashi, Kimihide Hasegawa, Hirokazu Kobayashi
