Abstract: A wireless remote control radio-transmits a vehicle height adjusting signal tagged with a remote control identification code in order to improve vehicle height adjustment operability in a vehicle such as a truck. The remote control identification code is pre-registered in a receiver, which, upon receipt of the vehicle height adjusting signal tagged with the remote control identification code, takes in the vehicle height adjusting signal. According to information contained in the received vehicle height adjusting signal, an air suspension ECU controls the supply and discharge of compressed air for air springs to adjust the vehicle height. When an emergency operation switch is operated, the vehicle height adjusting signal from the wireless remote control is disabled, and vehicle height adjustment is preferentially made based on a switching signal from the emergency operation switch.

The second arm has a drive plane. The third arm has a shaft member formed with a driven surface contacting with the drive plane. The displacement of the second arm is transmitted to the third arm with sliding between the driven surface and the drive plane.

Abstract: During a period in which a clutch is in a partially engaged state at the time of start of a vehicle, a transmission ECU calculates load acting on the clutch (clutch-absorbed energy). When this load is large, generation of a shift signal based on a gear shift map is prohibited, and the initial gear position is held. The clutch-absorbed energy is obtained through integration of the product of clutch transmission torque and the difference between rotational speed of an engine and rotational speed of the clutch. The clutch transmission torque is determined with reference to a clutch transmission torque map provided in the transmission ECU.

Abstract: A hand pattern switch device recognizes a hand pattern from an image of a hand in an image pickup zone and detects a hand motion. One of controlled objects is selected based on the recognized hand pattern and/or hand motion. In accordance with the selected object, a mode of detection of operation information based on hand motion is changed. In a moved distance detecting mode, a moved distance of the hand in the zone is detected as operation information, and in a stop time detecting mode, a stop time of the hand at a stop position to which the hand has been moved in the zone is detected as operation information. The image pickup zone is at a location which is located laterally to a steering wheel and to which a driver can extend his/her arm without changing a driving posture.

Abstract: An enlargement button that instruct enlargement of first to fourth buttons to is displayed on a display. The first to fourth buttons to are used to instruct the operation of a control device to be controlled by an electronic control unit to which a trouble diagnosing device is connected. When the enlargement button is manipulated, the first to fourth buttons to are enlarged in the display respectively in corners sections created by dividing the display screen substantially equally into four. With this arrangement, the operator no longer needs to monitor the first to the fourth button by eyes for manipulating these buttons, thereby improving the operability.

Abstract: A voltage converting circuit for electric vehicles that is capable of stably performing precharge control from a high voltage battery to an inverter. The voltage converting circuit includes a high voltage battery for supplying electric power to a vehicle drive motor; and an inverter, which is interposed between the high voltage battery and the vehicle drive motor and has a capacitor, for converting a direct current, supplied from the high voltage battery, to an alternating current and supplying to the vehicle drive motor.

Abstract: Immediately before fuel pressure is increased by a pressure-increase mechanism, a pressure-increase control valve of each cylinder is opened in timing that does not overlap the timing of opening of an injection control valve, and the period of time for which the pressure-increase control valves is opened is gradually increased. As a result, it is possible to prevent the quantity of fuel consumed by the pressure-increase mechanism from rapidly increasing when the increase of fuel pressure is started.
