The object lowering device comprises a pedestal and a swing. The swing includes a seat plate on which an object is placed, and is disposed on the pedestal. The pedestal is tilted with the lower corner of one side in the swinging direction of the pedestal as an axis, and the seat plate of the swing moves down to the ground, whereby the object is lowered to the ground.

Object lowering device and object raising and lowering device

The jack includes an upper support portion (upper plate) fixed to the lower portion of the vehicle body, and an airbag provided below the upper support portion (upper plate) and inflated and deployed by the supply of gas. According to the jack, the airbag is inflated and deployed under the vehicle body by the supply of the gas. When the gas is further supplied to the airbag in contact with the ground, the vehicle body fixed to the upper support portion (upper plate) is lifted. When the vehicle body is lifted in this manner, the state of contact between the wheels and the ground is changed, and the vehicle can escape from the stacked state.

Jack, vehicle, and jack-up system

A vehicle includes a main motor for traveling and an electronic control unit that controls the main motor. The electronic control unit is configured to: extract, from time series data of a rotation speed of the main motor, vibration data in a predetermined frequency band that includes resonance frequency of a drive system that includes the main motor; lower an upper limit value of output torque of the main motor from a normal upper limit value to a first upper limit value lower than the normal upper limit value when magnitude of vibration obtained from the extracted vibration data exceeds a first threshold value; and lower the upper limit value of output torque of the main motor to a second upper limit value lower than the first upper limit value when the magnitude of the vibration exceeds a second threshold value larger than the first threshold value.

Vehicle

There is provided a driving control device of an opening and closing body, which drives the opening and closing body in a closed state by a motor through an idling section thereof. The device includes a calculation section for calculating a rotation speed difference between a rotation speed of the motor in the idling section and a current rotation speed of the motor; and an insertion detection section for detecting insertion of a foreign member based on the calculated rotation speed difference and a predetermined threshold value. The threshold value monotonously decreases according to an increase in the rotation amount of the motor to coincide with a fully-closed state threshold value at a predetermined rotation amount of the motor within an error range of the rotation amount corresponding to the fully-closed state, and to maintain the fully-closed state threshold value to a maximum rotation amount in the error range.

Driving control device of opening and closing body for vehicle

A computing device computes at least one index value for an execution history of opening/closing movement of an openable and closable member. A sensing device outputs signals one after another in response to a change in a rotational state of the electric motor, which is sensed by the sensing device. A setting device sets a masking range for at least one of the signals based on the at least one index value. A determination device determines whether an object is pinched by the openable and closable member based on at least another one of the signals, which is outputted in a range other than the masking range, without referring to the at least one of the signals in the masking range during execution of the opening/closing movement of the openable and closable member.

Openable and closable member control apparatus and vehicle having the same

An opening-and-closing member drive control apparatus for a vehicle for driving the opening-and-closing member so as to be opened or closed by means of a driving force of a motor after an idling period or an idling section of the motor includes a moving speed detecting member, calculating means for calculating a moving speed changing value, a determining means for determining a sandwiching of an object on the basis of a relationship between the calculated moving speed changing value and a threshold value, a temperature estimating means for estimating a temperature of the motor on the basis of a rotational speed of the motor, detected in the idling period or the idling section, and correcting means for correcting the threshold value so that a determination sensitivity of the sandwiching of the object becomes greater when the estimated temperature of the motor is low than when the estimated temperature of the motor is high.
