In a vehicle including a shift-by-wire (SBW) transmission which may be parked in the neutral gear position of the transmission, method for controlling parking thereof includes determining whether the vehicle is in a situation in which neutral parking is required according to sensor information, when the vehicle is stopped, outputting first information configured to get a confirmation on whether a driver intends to perform the neutral parking from the driver, when the controller concludes that the vehicle is in the situation in which the neutral parking is required and when a park (P) gear position is input or an ignition of the vehicle is turned off, and controlling the SBW transmission to shift to a neutral (N) gear position, when there is an agreement input as a response to the first information.

The invention relates to a hydraulic system for a vehicle transmission, comprising: a hydraulic circuit arranged for generating a pressure, a hydraulic actuator arranged for engaging a park lock system, wherein the hydraulic actuator is hydraulically connected to the hydraulic circuit for actuation of the hydraulic actuator using the pressure, and a back-up system configured to keep he pressure above a predetermined pressure threshold for maintaining an actuation of the hydraulic actuator for a predetermined period of time in case of an operational interruption of a transmission control unit of the vehicle.

A commercial vehicle with at least one driven axle, at least one service brake, at least one propulsion engine, and wheels characterized in that the parking brake function of the vehicle is solved by a bistable locking means acting on both wheels. At least one multi-speed gearbox is provided to concurrently activate a first gear stage and a second gear stage having different ratios.

A vehicle park lock control method is presented with range positions including a P-range position and an N-range position in each of which a driving force is prevented from being transmitted to a driving wheel of a vehicle. A park lock mechanism is activated when in the P-range position. An operator is allowed to select whether or not to cause the park lock mechanism to be activated in response to key-off operation when in the N-range position. In response to continuous shifting of a range selector to one or more specific ones of the range positions, the park lock mechanism is prevented from being activated in response to key-off operation when in the N-range position.

An actuation mechanism for use in a vehicle. The actuation mechanism includes one or more motors having an output shaft with a sun gear. At least a portion of the sun gear is drivingly connected to at least a portion of one or more planetary gears. The one or more planetary gears are drivingly connected to at least a portion of a carrier, a fixed non-rotating ring gear and an output gear. The disclosure further relates to a method of operating an actuation mechanism that is drivingly connected to at least a portion of a vehicle parking mechanism. The method includes providing an actuation mechanism, providing a parking mechanism and one or more sensors that are operably configured to collect an amount of data to be analyzed. Based on the data analyzed, one or more failures within the parking mechanism may be determined and an alert may be sent.

A drive device for a PTO shaft includes a parking switch to detect a parking state of a vehicle body, a permission switch constituted of a self-returning switch and connected to the parking switch, the permission switch being configured to be switched to permit driving a PTO shaft, the PTO shaft being configured to be driven by a power of a prime mover disposed on the vehicle body, and a first switch device to be switched to enable the PTO shaft to be driven when the permission switch is switched to permit driving the PTO shaft under a state where the parking switch detects the parking state of the vehicle body.

A control device (10) for a parking brake device has an electronic device (12) by means of which, in the event of failure of a power supply system of a vehicle equipped with the control device (10) and the parking brake device during a procedure for parking the vehicle, at least one activation signal (14) can be output to a triggering device (16) of the parking brake device, so that the triggering device (16) can be activated by means of the at least one activation signal (14) and the parking brake device can be transferred to a locking mode by means of the activated triggering device (16), such that the vehicle is locked in its current parking position by means of the parking brake device present in its locking mode.

A park lock assembly for a vehicle transmission includes a toothed park lock gear and a moveable locking pawl that is moveable between an engaged state, in which the locking pawl is in locking engagement with the park lock gear, and a disengaged state, in which the park lock gear is freely rotatable relative to the locking pawl. The park lock assembly also includes an inductive angular position sensor located on an axial side of the park lock gear and configured for detecting angular position of the park lock gear.
