A flood sensing device includes: an acquiring section that acquires plural types of traveling state data relating to traveling of a vehicle; and a sensing section that senses flooding of a road on which the vehicle travels by using (a) a physical quantity that is estimated on the basis of (i) a vehicle behavior model, which is configured by driving force of the vehicle and traveling resistance that includes air resistance applied to the vehicle, slope resistance applied to the vehicle and rolling resistance applied to the vehicle, and which determines the physical quantity that varies due to the vehicle traveling, and (ii) the plural types of traveling state data of the present time that are acquired by the acquiring section, and (b) the physical quantity that is obtained from the traveling state data of the present time that is acquired by the acquiring section.

Flood sensing device, flood sensing system, and non-transitory computer readable medium

A flood detection device and method that acquires meteorological data; acquires traffic volume data representing vehicle traffic volume; and determines that an area, in which a vehicle traffic volume during or after rain is less than or equal to a predetermined number of vehicles, is flooded based on the meteorological data and the traffic volume data, when a probability, that the vehicle traffic volume in a normal time is less than or equal to the predetermined number of vehicles, is less than a predetermined value, the normal time being a state in which a rainfall amount is less than a predetermined value.

When imbalance diagnosis is not executed, target fuel pressure is set based on a rotation speed and volumetric efficiency of an engine, and when the imbalance diagnosis is executed, fuel pressure smaller than the target fuel pressure settable when the imbalance diagnosis is not executed is set as the target fuel pressure, and a high-pressure fuel pump that supplies fuel to a delivery pipe connected to the in-cylinder injection valve, is driven and controlled such that detected fuel pressure becomes the target fuel pressure. With this, it is possible to execute the imbalance diagnosis with higher accuracy.

Control device for internal combustion engine using imbalance diagnosis and abnormality determination

A motor control device includes a master-shaft drive device to drive a master-shaft motor, and a slave-shaft drive device to drive a slave-shaft motor, the motor control device including a correction-amount calculation unit to use a detection result of a position of the master-shaft motor and a detection result of a position of the slave-shaft motor to calculate a correction amount for correcting a speed command that is to be used for controlling the master-shaft motor, a correction unit to use the correction amount to correct the speed command that is to be used for controlling the master-shaft motor, and a position control unit to execute position control on the slave-shaft motor by using the detection result of the position of the master-shaft motor as a position command.

Motor control device

A damper structure for a gear device, which includes a first gear mounted to turn with respect to a shaft in a circumferential direction, a second gear mounted on the shaft to rotate integrally, a stopper rubber mounted on the second gear to face the first gear, and a pressing protrusion at the first gear to face the second gear. The stopper rubber is configured to be elastically deformed by pressing the pressing protrusion in a circumferential direction of the second gear during rotation of the first gear and be restored to the initial shape by separating the pressing protrusion during stop of the first gear. A recess for accumulating lubricating oil in the first gear is formed to face the stopper rubber.

Gear device

In the case where DC power from a DC power supply is converted to AC power by an inverter and supplied to an AC motor, a power compensator is connected in parallel with a DC power input portion of the inverter, and a control device of the power compensator charges/discharges a power storage device to perform a power compensation process A when power demand for the AC motor exceeds a predetermined value, and takes into account power allowance which can be inputted and outputted from the DC power supply to the power storage device and performs a power storage adjustment process B of performing auxiliary charge of the power storage device within the range of the power allowance when the power compensation process A is unnecessary.
