A parking assist apparatus includes a CPU for obtaining image data from a camera mounted on a vehicle, an image memory for storing the obtained image data as recorded image data, and an image processor for recognizing an object based on the image data. The image processor determines when to display a parking assist image to reveal an area hidden as a blind spot of the camera when the recognized object is in the blind spot of the camera and displays the parking assist image combining both current image data and the recorded image data for the area currently hidden as the blind spot of the camera, together with an indicator indicating the current position of the vehicle superimposed on the display.

Parking assist method and a parking assist apparatus

A battery box housing a battery is mounted between left and right side frames extending in a longitudinal direction of a vehicle body so that the battery box is offset to a left side of the vehicle body, and an intake duct and an exhaust duct for cooling air for cooling the battery are connected to an end of the battery box on a right side of the vehicle body. Therefore, it is possible not only to protect the battery between the left and right frames from a shock caused upon a side collision, but also to ensure a space for disposition of the intake duct and the exhaust duct while ensuring a volume of the battery box to the maximum. Moreover, the battery box is connected at its left and right ends to the left and right side frames.

Provided is a mounting structure for a battery in an electric vehicle capable of increasing a driving distance of the electric vehicle by mounting a plurality of battery modules in an existing vehicle body of en electric vehicle. The mounting structure for a battery in an electric vehicle according to an exemplary embodiment of the present invention includes a main relay box electrically connected with an inverter, a plurality of first battery modules mounted beneath the rear seats of the electric vehicle, and a main housing positioned between a pair of front seats in the electric vehicle and below the rear seat. More specifically, the main housing is configured to house the main relay box and first battery modules therein, and is fixed to the vehicle body of the electric vehicle.

Mounting structure for battery in electric vehicle

A cooling system for a battery in a vehicle does not use air from the vehicle passenger compartment, but rather, takes in ambient air from outside the vehicle. When the temperature of the ambient air outside the vehicle is low enough, the air is moved through a duct system by a pair of fans and blown across a battery assembly. When the temperature of the ambient air outside the vehicle is too warm to cool the battery directly, it is first passed through an evaporator coil where it exchanges heat with a refrigerant, prior to being blown across the battery assembly. The cooling air may be recirculated across the battery assembly, or exhausted from the vehicle through an air extractor.

Cooling system for a vehicle battery

A vehicular electrical equipment unit heating and cooling system includes a vehicular electrical equipment unit 10 including a battery 21 and an inverter YBU5 22 which are accommodated in a primary air passageway 14, an air inlet 44 through which air in a passenger compartment 6 is admitted to the primary air passageway 14, an air outlet 46 through which air flowing in the primary air passageway 14 is discharged to the outside of the electrical equipment unit 10, a subsidiary air passageway 30 connected to and cut off from the primary air passageway 14 to make a closed circuit 60 when connected to the primary air passageway 14, and a fan 40 for generating a flow of air in the primary air passageway 14.

Vehicular electrical equipment unit heating and cooling system and hybrid vehicle

An electric power unit is composed of a secondary battery, a cooling fan, a fan motor and a case for the secondary battery, the cooling fan and the fan motor. The case has a partition for isolating the fan motor from the secondary battery and cooling fan. A magnetic joint is disposed between the motor and the cooling fan.

In determining a starting point of a motor of an electric actuator during its initialization procedure, when a rotation angle sensor detects pulse signals in a certain initialization pattern, power supply to the motor is stopped by the control of a motor drive circuit. This electrical control of motor rotation enables the initialization procedure of the actuator to be carried out without using mechanical restriction means for locking purposes, and the influence of variations in the deflection amount of any stoppers is eliminated. The precision in determining the starting point in the initialization procedure is thus improved.

Electric actuator system

There are provided an air mixing door, a plurality of outlets for blowing air into respective portions in a vehicle compartment, outlet mode doors for switching a outlet mode by closing and opening the plurality of outlets, and one motor actuator for driving the air mixing door and the outlet mode doors. The outlet mode doors and the air-mixing door are alternately driven through a change of an operation angle of the motor actuator.

Air conditioner for vehicle and air conditioning unit driving apparatus

An actuator control device includes an electrical control unit for detecting the present positions of output shafts of servo motors, and communicating with control circuits for driving the output shafts of the servo motors to target stop positions on the basis of the present positions thus detected. When it is judged that a present position of one of the output shafts thus receives is abnormal, the electrical control unit corrects the present position and transmits the corrected present position to the appropriate control circuit.

Actuator control unit

An actuator, operated by being supplied with electric power, needs an initial setting for performing a desired operation by recognizing its starting position. The initial setting is conducted when an abnormality occurs in a signal which represents an operation of the actuator. The initial setting is also conducted when a system for the actuator recognizes a fact that a battery is electrically disconnected in association with information denoting a condition of the battery in a memory.
