Description

Automotive transmission and control method thereof}

The present invention relates to a vehicle transmission device and a control method thereof, and more specifically, to a vehicle transmission device and control method that allows a driver to select a gear shift.

The transmission can vary the gear ratio to keep the engine rotation constant depending on the vehicle speed, and the driver operates the shift lever to change the gear ratio of the transmission.

Shift modes of such a transmission device include a manual shift mode in which the driver can switch gears, and an automatic shift mode in which the gears are automatically switched according to the vehicle speed when the driver selects a drive range (D).

In addition, a sport mode type transmission device that can perform manual shifting and automatic shifting in one transmission device is being used. The sport mode type transmission basically performs automatic shifting, but can be equipped with a manual shifting gear next to the automatic shifting gear so that the driver can shift manually by increasing or lowering the gear. there is.

The shift lever is exposed inside the vehicle for the driver to operate, and most shift levers are installed between the vehicle's center fascia and console box.

Generally, the shift lever can be divided into joystick mode or rotary mode or stow position mode (hidden knob mode). For example, in the case of joystick mode, the shift lever is protruded to the outside of the vehicle and moves forward and backward to select the shift range, so space is needed according to the movement trajectory of the shift lever, so it is necessary to design it to prevent interference with the surroundings. do.

The rotary mode protrudes to the outside of the vehicle, but its height is insignificant compared to the joystick mode, and it allows shifting by rotation, reducing the space required and increasing space utilization of the vehicle.

In addition, the stow position mode is used when the vehicle's shifting device is not used with the knob of the vehicle's shifting device not protruding to the outside of the vehicle but retracted into the interior of the vehicle to form the same plane as the surrounding area, for example, when the vehicle's shifting device is parked. It can be used in a stationary or stationary state.

However, since each driver's preferred mode is different depending on the vehicle driving situation, there is a need for a method that can provide various modes so that the driver can select a preferred mode according to the vehicle driving situation.

In addition, it can be utilized as a cover area arranged around the lever according to each driving mode of the vehicle transmission system. In particular, there is a need for a method that can utilize the upper surface of the knob and the cover area around the knob in various ways during the stow position mode.
