A vehicle control unit and a vehicle equipped with the vehicle control unit are provided, the vehicle control unit being capable of preventing a shift change from being permitted in a direction opposite to a vehicle traveling direction caused by an erroneous operation of a shift lever during a traveling mode. In the vehicle control unit for controlling the vehicle on the basis of a shift range detecting unit configured to detect a shift range selected by a shift operation and a vehicle speed detecting unit configured to detect a vehicle speed, when the shift range detecting unit detects the shift range in a direction opposite to the vehicle traveling direction in a state where the vehicle speed detecting unit detects a vehicle speed not less than a first speed V, the vehicle control is carried out so that a compulsory deceleration is carried out by means of a deceleration unit provided in the vehicle instead of permitting the shift change corresponding to the shift range, the shift change being desirably permitted when the vehicle speed detecting unit detects that the vehicle speed decreases down to a vehicle speed not more than the first speed V.

Vehicle control unit and vehicle equipped with the same

A control deviceof an industrial vehicle which performs the control of actuating a parking brakeduring operator's absence in an industrial vehicle includes a seat switch, a vehicle speed sensor, and the parking brakecontrolled by a parking brake solenoid, and a counterwhich counts the elapsed time after the seat switchdetects the operator's absence. The control device sets the time corresponding to the time until the operator leaves the vehicle after the operator leaves the seat as a preset absence time. When the seat switchhas detected absence, a control signal which validates the parking brakeis output to the parking brake solenoid, thereby actuating the parking brakeif the vehicle speed shows a vehicle stopped state, and the elapsed time becomes equal to or more than the set absence time.

Control device of industrial vehicle, and industrial vehicle loaded with the device

In a vehicle control unit for controlling a vehicle based on a detection signal obtained from a shift range detecting unit that detects a shift range selected by a shift operating unit, a vehicle speed detecting unit that detects a vehicle speed, and an engine rpm detecting unit that detects an engine rpm, when the detected vehicle speed is less than a reference vehicle speed, the shift range detecting unit detects that a shift switching operation is carried out from a neutral to a forward range or a reverse range, and the engine rpm detecting unit detects that the engine rpm is not less than a predetermined value until a time not less than a predetermined time is elapsed from when the shift switching operation is detected, a control for prohibiting a shift change of a transmission in accordance with the shift switching operation is carried out.

A vehicle control device has a control devicemounted on a vehicle including an accelerator opening detecting sensor, a vehicle speed sensor, and braking meanscapable of adjusting deceleration of the vehicle. The control device stores a plurality of deceleration tablesin which the deceleration is set according to a predetermined parameter. If the detected vehicle speed is equal to or less than a preset vehicle speed Vand the detected accelerator opening is equal to or less than a preset accelerator opening when a target deceleration is selected by the deceleration selecting meansand, the selection of the deceleration is validated, a deceleration tablecorresponding to the deceleration selected by the deceleration selecting means is read, and the braking means is actuated on the basis of braking parameters specified in the table, thereby executing deceleration control to provide the selected deceleration.

Vehicle control device and vehicle mounted with the device

A control system of an industrial truck includes a first switch, a second switch and a hydraulic circuit. The first switch detects whether an operator sits on a seat, and carries out a first operation based on the result. The second switch detects whether a device for operating an actuator is operated, and carries out a second operation based on the result. The hydraulic circuit is used for operating the actuator. It a control valve, a first circulating line, a hydraulic line and a drive lock valve. The control valve includes a spool whose position is changed by the device. The first circulating line includes the control valve, through which the hydraulic fluid circulates. The hydraulic line connects the spool with the actuator. The drive lock valve is provided for the hydraulic line and blocks the hydraulic line, based on the first operation and/or the second operation.

Control system of industrial truck and controlling method of the same

A self propelled industrial machine includes a self propelled vehicle body, a transmission installed in the self propelled vehicle body, an operator presence detection switch and a control unit. The operator presence detection switch is provided to generate an operator presence or absence signal relating to an operator on a seat arranged on the self propelled vehicle body. The control unit is provided to set the transmission to a neutral state in response to the operator absence signal.
