A method of automatically controlling vehicle auto-hold includes: collecting information on a vehicle traveling condition that applies when a driver operates a brake pedal while a vehicle is traveling; selecting learning data for learning on a pattern of a driver's operation from among pieces of the information collected in the collecting of the information on the vehicle traveling condition and storing the selected learning data; performing the learning on the pattern of the driver's operation based on the learning data and generating a categorization model for the pattern of the driver's operation according to a result of the learning; and determining whether or not to cause the auto-hold switch to enter an automatic operation mode while the vehicle is traveling, using the categorization model, and selectively causing the auto-hold switch to enter the automatic operation mode according to a result of the determining.

A method for operating a dual clutch transmission of a motor vehicle having a first partial transmission, a second partial transmission, and a transmission output shaft common to the partial transmissions and drivable both by the first partial transmission and by the second partial transmission, in which the dual clutch transmission is in a parking lock state in which two gears of one of the partial transmissions are engaged simultaneously. The following steps are carried out to exit the parking lock state: Introducing a torque caused by a drive element of the motor vehicle via the transmission output shaft common to the one partial transmissions into the one and/or other partial transmission while the gears of the partial transmission are engaged; and disengaging at least one of the gears of the one partial transmission engaged simultaneously in step a).

A park brake system for adjusting a tension in a brake cable that is coupled to a park brake. The park brake system can include a driver that is communicatively coupled to a microcontroller, and an actuator that is rotatably displaceable by operation of the driver. An equalizer assembly can be linearly displaced along the rotating actuator to adjust a tension in the brake cable. The microcontroller can monitor a current being drawn by the driver as the driver is operated, and generate instructions to cease operation of the driver upon the current reaching a predetermined current threshold that corresponds a maximum force that is to be applied by the park brake. The microcontroller can also, when the park brake is being released from a set position, count pulses outputted by an encoder in connection with determining whether the park brake has reached a running clearance position.

A method for reinforcing safety of a vehicle on a ramp applied to a vehicle is performed by a first priority anti-skid countermeasure control in which a brake is operated together with displaying an occurrence of the skid of a vehicle/vehicle stop message on a ramp by a controller when the vehicle starts, a second priority anti-skid countermeasure control in which compensating an idle torque is performed together with displaying a guidance of anti-skid function operation/vehicle stop message is performed, a third priority anti-skid countermeasure control in which displaying a turn-off/vehicle stop message is performed, and a fourth priority anti-skid countermeasure control in which forcibly shifting to a N (neutral) stage or permitting the shift together with displaying a forcibly switching to the shift stage N stage/vehicle stop message is performed.

A method for maintaining idle noise refinement in a vehicle is provided. The method may include performing a D-range neutral control, wherein a controller is configured to apply auto hold threshold values to conditions for entering an auto hold control in a neutral control state, and wherein the auto hold threshold values are determinant of an entry into the D-range neutral control such that the auto hold threshold values limit the conditions for entering the auto hold control.

A vehicle includes a powertrain and an electric parking brake. A controller activates the electric parking brake in response to the powertrain transitioning to an off state that inhibits production of propulsive torque during an ignition cycle when a vehicle speed is less than a predetermined speed and in a presence of conditions that inhibit the powertrain from transitioning to an on state that permits production of propulsive torque.

Methods and systems for monitoring a switch included in a vehicle. One method includes a method of monitoring a switch included in a vehicle. The method includes obtaining a current vehicle speed, and dynamically, by a controller, generating a duration for detecting a stuck state of the switch based on at least the current vehicle speed, detecting, by the controller, a duration of a high signal received from the switch. The method also includes comparing, by the controller, the duration of the high signal to the generated duration, and detecting, by the controller a stuck state of the switch when the duration of the high signal satisfies the generated duration.
