A parking assist apparatus (13) has: a learning device (131) configured to perform a learning operation for learning, as a target parking position, a position in which a vehicle is parked when the vehicle is parked by a driver's operation; and an assisting device (132) configured to perform a parking assist operation for automatically parking the vehicle in the target parking position on the basis of a learning result of the learning device, if a predetermined condition that there is a predetermined difference between a position of an occupant during an assist period and a position of an occupant during a learning period is satisfied, the assisting device adjusts the target parking position on the basis of the difference so that it is easier to get out of the vehicle after the parking assist operation is finished, compared to a case where the predetermined condition is not satisfied.

The present invention proposes a transmission control device capable of shortening a switching time between forward control and reverse control of a transmission. The present invention relates to a transmission control device that controls a transmission, including: a forward power transmission mechanism configured to move a vehicle forward; and a reverse power transmission mechanism configured to reverse the vehicle. Each of the forward power transmission mechanism and the reverse power transmission mechanism includes a driving-side connector and a driven-side connector. The forward power transmission mechanism and the reverse power transmission mechanism are configured to be capable of changing a contact state where the driving-side connector and the driven-side connector are pushed to contact each other, a retracted state where pushing forces are released to retract the driving-side connector and the driven-side connector, and an intermediate state formed as the intermediate state between the contact state and the retracted state. When the vehicle is controlled based on a previously-generated control content including switching between forward control and reverse control, one of the forward control and the reverse control is performed by controlling one power transmission mechanism between the forward power transmission mechanism and the reverse power transmission mechanism to the contact state while controlling the other power transmission mechanism to the intermediate state.

There is provided a parking assist system. A motor drives a front wheel. A motor control device controls an output of the motor. A changeover switch changes over a control mode for the motor to an assist mode different from a normal traveling mode. The motor control device is configured to control the output of the motor depending on operation of the changeover switch at the assist mode.

A parking system includes a parking lot having a plurality of parking spaces for parking motor vehicles. In the parking system, a motor vehicle is able to be controlled in an autonomous manner on a route between a parking area and one of the parking spaces. A verification method for the parking system includes steps of the autonomous travel of the route by a test vehicle, determining whether the travel of the route is taking place correctly, and clearing the parking system for use by vehicles that correspond to the vehicle type of the test vehicle.

A method for producing sensor information depends on a rotational speed, using a rotational speed sensor which is adapted to output rotational speed pulses in predetermined angular positions of a physical sensor field that rotates at the rotational speed. In order to increase resolution, a digital angle signal each is determined between the pulses. A defined number of most significant bits of said angle information is output to determine the rotational speed so that the interval between two pulses is subdivided into a defined number of subintervals. An angle value which can be unambiguously interpreted by means of the sinusoidal signal can be determined from the cosine signal by using two phase shift sinusoidal signals and an arccos function. The device optionally outputs the angle signal below a threshold value and an impulse signal above the threshold value to determine speed.
