Claims (9)

1. Автомобиль, содержащий коробку передач, устройство для управления автоматическим сцеплением в цепи привода, исполнительный узел для регулирования передаваемого сцеплением крутящего момента, управляемый блоком управления, который находится в сигнальной связи с датчиками и, при необходимости, другими электронными устройствами, например через сигнальные провода и/или шину данных, причем блок 13 управления вычисляет или определяет пробуксовывание сцепления в зоне фрикционных накладок и посредством пробуксовывания сцепления и с помощью передаваемого сцеплением 3 крутящего момента определяет ввод энергии в зону фрикционных накладок сцепления и/или определяет повышение температуры фрикционных накладок относительно задаваемого предельного значения и/или определяет повышенный износ фрикционных накладок, отличающийся тем, что при повышенном по сравнению с предельным значением вводе энергии или при повышенной по сравнению с предельным значением температуре и/или при повышенном по сравнению с предельным значением износе блок управления на первой временной фазе с продолжительностью t1 управляет передаваемым моментом сцепления независимо от влияния имеющегося ввода энергии, затем на второй временной фазе с продолжительностью t2 управляет передаваемым сцеплением крутящим моментом с изменением по времени, например в виде импульсов, а на третьей временной фазе с продолжительностью t3 повышает передаваемый сцеплением крутящий момент до тех пор, пока частота вращения двигателя не будет ниже порогового значения nMOT_SCH или пока не истечет продолжительность t3.1. An automobile comprising a gearbox, an automatic clutch control device in the drive circuit, an actuating unit for adjusting the clutch torque transmitted by the control unit, which is in signal communication with sensors and, if necessary, other electronic devices, for example, via signal wires and / or a data bus, the control unit 13 calculating or determining slipping of the clutch in the area of the friction linings and by slipping the clutch and using the torque transmitted by the clutch 3 determines the energy input into the area of the friction clutch plates and / or determines the temperature increase of the friction linings relative to the set limit value and / or determines the increased wear of the friction linings, characterized in that when the energy input is increased compared to the limit value or when compared to the temperature limit value and / or when the wear is increased compared to the limit value, the control unit in the first time phase with with falseness t 1 controls the transmitted clutch moment regardless of the influence of the available energy input, then in the second time phase with duration t 2 controls the transmitted clutch torque with time variation, for example in the form of pulses, and at the third time phase with duration t 3 increases the transmitted clutch torque until the engine speed is below the threshold value n MOT_SCH or until the duration t 3 expires. 2. Автомобиль по п. 1, отличающийся тем, что по истечении третьей временной фазы с продолжительностью t3 или в течение нее при достижении порогового значения nMOT_SCH частоты вращения двигателя снова начинают первую временную фазу с продолжительностью t1.2.

The car according to claim 1, characterized in that at least the individual durations t 1 , t 2 and / or t 3 can be set by the control unit 13 with the possibility of change or constant. 5. Автомобиль по п. 1, отличающийся тем, что, по меньшей мере, отдельные продолжительности t1, t2 и/или t3 могут быть выбраны блоком 13 управления в зависимости от передачи.5. The vehicle according to claim 1, characterized in that at least the individual durations t 1 , t 2 and / or t 3 can be selected by the control unit 13 depending on the transmission. 6. Автомобиль по п. 1, отличающийся тем, что в течение второй временной фазы до истечения продолжительности t2 преждевременно заканчивают вторую временную фазу, когда предварительно выбранная частота вращения на входе коробки передач достигает задаваемого порогового значения nGET_SCH или превышает его.6. The vehicle according to claim 1, characterized in that during the second time phase before the duration t 2 expires, the second time phase ends prematurely when the preselected speed at the gearbox input reaches or exceeds a predetermined threshold value n GET_SCH . 7. Автомобиль по п. 1, отличающийся тем, что пороговое значение nMOT_SCH равно пороговому значению nGET_SCH.7. The vehicle according to claim 1, characterized in that the threshold value n MOT_SCH is equal to the threshold value n GET_SCH . 8. Автомобиль по п. 1 и/или 7, отличающийся тем, что пороговое значение nMOT_SCH отличается от порогового значения nGET_SCH.8. The vehicle according to claim 1 and / or 7, characterized in that the threshold value n MOT_SCH is different from the threshold value n GET_SCH . 9. Автомобиль по одному из пп. 1 и/или 6-8, отличающийся тем, что, по меньшей мере, пороговое значение nMOT_SCH и/или пороговое значение nGET_SCH выбирают с помощью блока управления в зависимости от передачи.9. The car according to one of paragraphs. 1 and / or 6-8, characterized in that at least a threshold value n MOT_SCH and / or a threshold value n GET_SCH is selected using the control unit depending on the transmission.
