Description
Изобретение относится к безрельсовым транспортным средствам и может быть использовано в алгоритмах автоматического управления движением сочлененных автобусов и других, в том 5 числе грузовых, автопоездов.The invention relates to roadless vehicles and can be used in the algorithms for the automatic control of the movement of articulated buses and others, including 5 trucks, road trains.
Цель изобретения - предотвращение нарушения устойчивости траектории движения автопоезда при торможении.The purpose of the invention is to prevent violations of the stability of the trajectory of the trailer when braking.
Способ предотвращения чрезмерного *θ складывания автопоезда заключается в следующем.The way to prevent excessive folding of an autotrain is as follows.
В процессе торможения наблюдают за соответствием процесса изменения угла между звеньями автопоезда мате- 15 матическому предсказанию, заложенному в электронную память для данного изменения положения рулевого колеса. Несоответствие может заключаться в том, что мгновенные значения угла 20 между звеньями выше предсказанных,In the process of braking, one observes the correspondence of the process of changing the angle between the links of the autotrain to the mathematical prediction embedded in the electronic memory for a given change in the position of the steering wheel. The discrepancy may be that the instantaneous values of the angle 20 between the links are higher than those predicted,
При таком несоответствии экстренно снижают приводные усилия в тормозной системе, предпочтительно, сначала в тягаче,идущем вкачестве первогозвена автопоезда. Далее отслеживают изменение разницы между предсказанным и действительным углом до тех пор, пока разница перестанет увеличиваться и станет сокращаться. После этого начинают подтормаживать вращающийся элемент в сцепном устройстве между звеньями автопоезда и,прекратив растормаживание колесных тормозов, фиксируют достигнутое приводное усилие для этих тормозов.With this discrepancy, the drive forces in the braking system are urgently reduced, preferably, first in the towing vehicle as the first link of the train. Next, monitor the change in the difference between the predicted and actual angle until the difference ceases to increase and begins to shrink. After that, the rotating element in the coupling between the links of the train is started to brake and, stopping the release of the wheel brakes, fix the achieved driving force for these brakes.
Б результате, ресурс по боковому сцеплению колес автопоезда будет увеличен так, что угловые движения звеньев и автопоезда в целом по отношению к их номинальным положениям на заданной траектории погашаются сопротивлением уводу шин и торможение сцепки не приводит к потере устойчивости автопоезда в целом. Увеличение ресурса по боковому сцеплению, достигаемое с риском снижения тормозной эффективности, имеет место по фактической надобности, а не при всяком экстренном торможении, как это имеет место с регуляторами тормозных сил или антиблокировочными системами.As a result, the resource for lateral coupling of the wheels of the articulated train will be increased so that the angular movements of the links and the autotrain as a whole with respect to their nominal positions on a given trajectory are redeemed by the tire-drag resistance and the braking of the coupling does not lead to loss of stability of the autotrain as a whole. An increase in the lateral adhesion resource, achieved with the risk of a decrease in braking efficiency, takes place according to actual need, and not with any emergency braking, as is the case with brake force regulators or anti-lock systems.
