A slip control device, a slip control method, and a vehicle provided with such a slip control device are provided, with which the vehicle can travel stably even on a slippery road surface while maintaining good road holding. The device has torque directive control means () for calculating torque directives for the motors respectively based on accelerator pedal depressions () and steering angles () and outputting them to each of motor control sections () of the motors, first reference speed calculation means () for calculating a first reference speed of one of the pair of left and right motors to be controlled based on rotation speed of the other motor, and restriction applying means () for applying restriction to each of the torque directives based on a permissible speed range determined for each of the motors by applying prescribed permissible speed deviation to each of the calculated reference speeds.

Electric vehicle, and device and method of controlling slip thereof

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.

A body structure of a forklift truck is provided, with which no dead space is formed in a cross member while securing the constructional strength of the cross member, an increase in length of the truck body due to the space needed in the prior art to locate the exhaust muffler can be evaded resulting in a compact forklift truck, and winding-up of dust on the ground caused when the radiator cooling air flows to the underside of the truck body is prevented without an increase in manufacturing cost. The structure of the vehicle body having a cross member fixed to the inside faces of a pair of left and right side frames is characterized in that the cross member is composed of a vertical plate and a horizontal plate fixed to the vertical plate at a substantially right angle to form a crooked member having the general shape of an inversed letter 'L' with an axle support member fixed the lower end of the vertical plate.

The temperatures of exhaust gas streams into a black smoke eliminating device are uniformly raised to assuredly burn and eliminate the black smoke at the black smoke eliminating device. Accordingly, the restoration of the black smoke eliminating device is uniformly carried out while avoiding melt damage of the filter. Further, the exit temperature of the black smoke eliminating device is descended by a simple device of lower cost. For accomplishment of the present objects, the heating device and black smoke eliminating device are provided in a plural and divided manner and there are provided a baffle member and a space portion, to thereby equalize the volume quantities and temperatures of exhaust gas flows flowing into these devices. Further, the fuel is atomized into fine particles by injection into pressurized air and the obtained mixture is uniformly mixed into the exhaust gas, so that there are uniformly raised the temperatures of exhaust gas streams into the black smoke eliminating device. The temperature of exhaust gas is descended by a simple structure of porous body disposed downstream of the black smoke eliminating device.
