Abstract
Abstract In a battery powered vehicle such as an forklift truck, control data is stored in a memory (39) by an operation of the keys (11a, 11b, 11c, 11d, 11e) on a control panel (10) mounted at the operation seat, and a part of the control data is selected by a control circuit (30) and transmitted to a travelling control circuit. The travelling control circuit controls a travelling motor (101) with the characteristics decided by the selected data and the selected control data is indicated on a display panel (12). A plurality of data used for maintenance administration, such as a cumulative travelling distance or cumulative operating hours, are stored in a memory and one of the data for maintenance administration is arbitrarily indicated on the display panel (12) and converted to meet the specified indication specification through the control circuit (30) by operation of the keys (11e) on said control panel (10). The control and display system according to the present invention allows an operator to change the operating characteristic of the vehicle, to indicate the control data, to select the data for maintenance administration, to convert the data in the specified indication specification, and to indicate the data on the display panel (12), by an operation of the control panel (10).
