PCT No. PCT/DK88/00165 Sec. 371 Date Apr. 11, 1990 Sec. 102(e) Date Apr. 11, 1990 PCT Filed Oct. 10, 1988 PCT Pub. No. WO89/03343 PCT Pub. Date Apr. 20, 1989.When towing large aircraft with a tractor damage may at high speeds inadvertently be done to the nose wheel gears of the aircraft if the pilots of the aircraft apply the brakes. This can be avoided by automatic control whereby the transmitted force is sensed and the power and braking of the tractor is controlled on the basis of said sensing. By tractors of that kind it is difficult to sense the transmitted power directly. Instead, according to the invention, the acceleration of the tractor and the supplied power of the tractor are sensed. On the basis thereof it is possible to calculate the transmitted force and to drive accordingly. |
