Vehicle with a dual-clutch transmission

A vehicle with a dual-clutch transmission, the vehicle comprising:

• a first subtransmission and a second subtransmission, wherein each of the first subtransmission and the second subtransmission are activated by actuating a respective associated first separating clutch and a respective associated second separating clutch, and wherein each of the first subtransmission and the second subtransmission has at least one gearshift element, the at least one gearshift element being a synchronizing clutch with which a gear can be engaged;
• an evaluation module configured to control a shift control unit and a clutch control unit;
• the shift control unit configured to cause a gear shift from a current gear into a target gear of the first subtransmission;
• in preparation for the gear shift, the evaluation module is configured to control the clutch control unit to open, from a closed position, the first separating clutch of the first subtransmission in a separating clutch opening process so that a torque-free disengagement of the current gear is ensured;
• the evaluation module is further configured to control the shift control unit in order to disengage the current gear in the first subtransmission without torque in the gear disengagement process, the evaluation module being further configured to control the shift control unit so that the gear disengagement process starts before an expiration of the separating clutch opening process, thereby causing the separating clutch opening process and the gear disengagement process to temporally overlap in an overlap time interval,
• wherein the gear shift takes a time period, the time period including a first time period for the opening and a second time period for the disengaging, and wherein the first time period overlaps with the second time period.

A method for operating a dual-clutch transmission of a motor vehicle comprising:

• controlling, by an evaluation module, a shift control unit and a clutch control unit;
• shifting, by the shift control unit, a current gear into a target gear of a first subtransmission;
• opening, by the clutch control unit, the first separating clutch coupled to the first subtransmission to ensure a torque free disengagement of the current gear, wherein the first subtransmission comprises a synchronizing clutch that engages a gear;
• and
• disengaging, by the shift control unit, the current gear of the first subtransmission based on the opening the first separating clutch, the evaluation module controlling the shift control unit so that the disengaging starts before an expiration of the opening, wherein the shifting takes a time period, the time period including a first time period for the opening and a second time period for the disengaging, wherein the first time period overlaps with the second time period.
