<p>The output of an engine (1) is transmitted via a clutch to an automatic transmission (3) to drive the driving wheels (5) forward or backward via a differential gear mechanism (4). Based upon a direction point detected by a forward/backward sensor (19), brake controllers (38, 39) apply the braking force when the direction point of a forward/backward operation lever (20) is switched to a direction point opposite to the direction in which the vehicle is travelling. Based upon a discriminated result of discriminating means (31-34) which discriminate whether the travelling speed of the vehicle detected by a speed sensor (11) is decreased to a predetermined value, a command is given to drive the automatic transmission (3) for changing over when the speed of the vehicle is decreased to the predetermined value, and the forward or backward direction is changd by change control means (31-34).</p> |
