The present disclosure discloses a sensing system for sensing a position of a gear shaft. In the present disclosure, a magnet apparatus is provided on the gear shaft, where the magnet apparatus includes, along a rectilinear motion direction, a first length region magnet and a second length region magnet, the second length region magnet including a first portion and a second portion, a magnetic field of the second portion of the second length region magnet corresponding to a reverse gear position being different from that of the first length region magnet and that of the first portion of the second length region magnet. An actually induced electrical signal generated by sensing the motion of the magnet apparatus is different from a reference inductive electrical signal of a corresponding position of a reference magnet. The processing unit compares the inductive electrical signal generated by sensing the motion of the magnet apparatus against a simulated inductive electrical signal and determines whether the gear shaft is at a reverse gear position or a forward gear position based on a difference from the comparison.

The present disclosure discloses a sensing system for sensing a position of a gear shaft. The present disclosure may implement determination of whether the gear shaft is at a reverse gear position, a forward gear position or a neutral gear position by: partitioning a magnet into a first length region magnet and a second length region magnet, wherein the first length region magnet and the second length region magnet have different magnetic field directions, sensing and generating an inductive electrical signal reflecting motions of the first length region magnet and the second length region magnet; storing, by a memory unit, a first type reference signal for the first length region magnet and a second type reference signal for the second length region magnet, which are sensed by simulation; and comparing, by a processing unit, the inductive electric signal against the first type reference signal and the second type reference signal, which reflect different gear positions, respectively. By arranging only one magnet and one set of circuitry mechanical elements to sense a position of the gear shaft, the sensing apparatus according to the present disclosure effectively implements detection of the neutral gear position and the reverse gear position of the gear shaft, which reduces the manufacturing cost and lowers the failure rate.

[Object] To provide a shift control device that, in a shift control device of a vehicle equipped with an idling-stop mechanism and a shift-by-wire mechanism, is capable of preventing setting off at a timing that the driver does not expect when returning from an idling-stop state. [Solution] The SBW-CU (40) that constitutes the shift control device (1), in the case of selection information for selecting the R range being output during an idling stop, switches the shift range of the automatic transmission (10) to the R range when the vehicle is braked, and switches the shift range to the N range or the P range when the vehicle is not braked and the shift range of the automatic transmission (10) is the D range. Also, the SBW-CU (40), in the case of selection information for selecting the R range being output during an idling stop, maintains the shift range without switching it when the vehicle is braked and the shift range of the automatic transmission (10) is other than the D range.

A range determination device is applied to an automatic transmission provided with an input portion, an output portion, and a range switching mechanism which transmits rotation of the input portion to the output portion, and which is operative to switch the range of the automatic transmission between a forward range and a reverse range, in which directions of transmitting rotation from the input portion to the output portion are different from each other. The range determination device includes a rotational state detection unit which detects a rotational state of a predetermined rotary member included in the range switching mechanism, and a determination unit which determines that the forward range or the reverse range is attained on the basis of the rotational state of the rotary member detected by the rotational state detection unit.

A control device for a vehicle that includes a switching device for switching a power transmission device between a parking state and a non-parking state. The control device includes: (a) an opening/closing determination portion for determining whether a vehicle door is open or closed; (b) a switching control portion for executing an automatic parking control for switching the power transmission device to the parking state, in a case in which it is determined that the door is open, when a vehicle running speed is not higher than a predetermined speed, with the power transmission device being in the non-parking state, and (c) a reverse-parking determination portion for determining whether or not a vehicle driver is performing a reverse parking. The switching control portion does not execute the automatic parking control, in a case in which it is determined that the driver is performing the reverse parking.
