A vehicle drive device includes: a casing within which lubricating oil is received; a rotating electrical machine provided within the casing, and including a stator with a coil; a temperature sensor provided within the casing; and a control device that functions as: a coil temperature estimation device executing a first temperature estimation in which correlation with a detected temperature is relatively high, and a second temperature estimation in which the correlation is relatively low; a determination device determining whether or not positional relationship between the temperature sensor and oil level is in a permitted state that permits the first temperature estimation; and a limitation device limiting load factor of the rotating electrical machine based on a result of the first temperature estimation when being in the permitted state, and limiting the load factor based on a result of the second temperature estimation when not being in the permitted state.

Methods and systems are provided for aging a new plastic fuel tank in a vehicle. In one example, during a plug-in event to recharge a battery of the vehicle, the fuel tank is isolated and the fuel pump is actuated to agitate fuel within the tank and increase fuel vapors until the plastic fuel tank becomes aged to a predetermined degree by fuel vapors generated therein. In this manner, the fuel tank is aged more rapidly, resulting in more accurate fuel level readings and less noise and vibration.

A control apparatus of an automatic transmission connected to an internal combustion engine of a vehicle includes a determination unit configured to determine an operation state of a hydraulic oil temperature sensor based on comparison between a threshold and a difference between a hydraulic oil temperature of the automatic transmission and a cooling water temperature of the internal combustion engine. When the operation state of the hydraulic oil temperature sensor is determined as normal by the comparison with the threshold, the determination unit further determines the operation state of the hydraulic oil temperature sensor based on an operation state of an oil pressure sensor determined using the hydraulic oil temperature, an oil pressure of hydraulic oil, and a rotation speed.

To provide a battery device including a battery; a first cooling system having a first cooling fan and a first temperature sensor; a second cooling system having a second cooling fan and a second temperature sensor; and a controller, wherein the controller carries out abnormality determination with respect to a temperature sensor when a difference between the first cooling air temperature and the second cooling air temperature, detected by the first temperature sensor and the second temperature sensor, respectively, after elapse of a predetermined set period after a start switch of the vehicle is turned off while the first cooling fan and the second cooling fan remain stopped, is equal to or greater than a predetermined amount.

A vehicle with deployable pliable fairing skirts and a controller for controlling deployment of the skirts are provided. The pliable fairing skirts are deployable over openings of wheel wells for the vehicle to provide additional streamlining for the vehicle. The pliable fairing skirts are stowable when the brakes of the vehicle may benefit from additional cooling airflow. The skirts are also stowable when environmental conditions may result in damage to the skirts or when steerable wheels of the vehicle would protrude from the opening.

A method of determining the temperature of a motor winding of an electric motor, in particular of an electric door drive motor includes determining the electric resistance of the motor winding as a measure for the temperature. The method also includes the steps of providing the electric motor with at least one current sensing resistor and applying an electric voltage to the motor winding.

An engine device including a post-treatment device 20, provided in an exhaust passage of an engine 1, for purifying an exhaust gas from the engine 1. As the post-treatment device 20, a three-way catalyst 22 is used. The engine device further includes a filter case 31 including a filter body 32 for catching deposits in the exhaust gas. The filter case 31 is disposed, in a replaceable manner, upstream of the post-treatment device 20 in the exhaust passage.

A system to improve cold air flow to an area of a vehicle is disclosed. The system includes an air induction plenum, an air inlet passage fluidicly connected to the air induction plenum, and an air outlet passage fluidicly connected to the air induction plenum, and a fan. The fan creates a fan pressure to pull air into the air induction plenum.

A hydraulic park brake system for an aircraft may include a hydraulic park brake controller having a processor and a tangible, non-transitory memory configured to communicate with the processor. The tangible, non-transitory memory may have instructions stored thereon that, in response to execution by the processor, cause the hydraulic park brake system to perform various operations. Such operations may include receiving, by the processor, a hydraulic park brake condition, comparing, by the processor, the hydraulic park brake condition with a predetermined condition to yield comparison data, and determining, by the processor and based on the comparison data, a hydraulic park brake adjustment status. Such operations may further include generating, by the processor and based on the hydraulic park brake adjustment status, an adjustment command and transmitting, by the processor, the adjustment command to a hydraulic park brake of the aircraft.

A control apparatus of an automatic transmission connected to an internal combustion engine of a vehicle includes a determination unit configured to determine an operation state of a hydraulic oil temperature sensor based on comparison between a threshold and a difference between a hydraulic oil temperature of the automatic transmission and a cooling water temperature of the internal combustion engine.
