Vehicles, systems, and methods for shifting a manual transmission into neutral during autonomous braking are provided. An exemplary system for shifting a vehicle into neutral during autonomous braking includes a manual transmission for transferring power from an engine to a differential using gears manually selected by a gear selector. Also, the system includes an actuator mounted to the vehicle and to the gear selector. Further, the system includes a controller coupled to the actuator and configured to direct the actuator to force the gear selector into neutral during an autonomous braking event.

A control method for a vehicle with a DCT may include: a sensing step in which a controller senses a currently engaged gear of the vehicle, an inclination of a road, and a vehicle speed; a comparing step in which the controller compares a temperature of an odd-numbered clutch of the transmission with a set temperature when the currently engaged gear is a first gear, the inclination of the road is within a set range, and the vehicle speed is a set vehicle speed or less, after the sensing step; and an adjusting step in which the controller adjusts a shifting pattern to shift into a second gear when the temperature of the odd-numbered clutch is the set temperature or more, as the result of the comparing step.

A vehicle power transmission system includes: a transmission; a shift actuator; a clutch; a clutch actuator for mutually switching between the transmission and the shutting off of a driving force at the clutch; and a control device being configured to, when having detected that the vehicle is in the travelling state and that the clutch actuator is abnormal by use of the travelling state detection sensor and the CA abnormality detection sensor, control the operation of the shift actuator and cause the selected gear stage in the transmission to be shifted into neutral before the vehicle comes to a stop while shifting the selected gear stage in the transmission into a gear stage having a lower gear ratio.

A shifting control method for a vehicle with a dual clutch transmission is provided to achieve quick shifting and direct engaging through quick synchronous control of the rotational speed of an engine and cooperative control of engine torque when a driver intends to rapidly accelerate the vehicle while shifting. The method includes: a rapid acceleration determining step in which a controller determines whether the vehicle is rapidly accelerated based on an output value according to a driving state of the vehicle until a torque handover period is entered, when shifting is started; and an interlocking step of controlling the engagement clutch torque over a predetermined desired engagement clutch torque to cause interlocking based on a torque value determined in accordance with a rapid acceleration level determined in the torque handover period, when the controller determines that the vehicle is rapidly accelerated.

A shift control method for a vehicle with a Dual Clutch Transmission (DCT) includes comparing, by a controller, a current clutch temperature with a first predetermined reference value and a second predetermined reference value, the second predetermined reference value being greater than the first reference value, preventing, by the controller, coaxial power-on downshifting when the clutch temperature is greater than the first reference value, and reducing, by the controller, a shift time by preventing coaxial power-on downshifting when the clutch temperature is greater than the second reference value and then increasing a shift speed when biaxial full skip shifting is required.

A vehicle includes a transmission having a first neutral with a first combination of engaged clutches and a second neutral with a second combination of engaged clutches. The second neutral has more engaged clutches than the first neutral. A vehicle controller is programmed to, in response to a request to shift from the first to the second neutral and a failed-on clutch being detected, inhibit the shift to remain in the first neutral.

A vehicle includes a transmission having a first neutral with a first combination of engaged clutches and a second neutral with a second combination of engaged clutches. The first neutral has more engaged clutches than the second. A controller is programmed to, in response to a request to shift from a drive gear to the first neutral and a clutch of the drive gear being failed-on, shift to the second neutral.
