20140114574 | NAVIGATION METHODS AND APPARATUS - A method of operating a navigation apparatus is provided. A calculated route is shown on a map display of the apparatus together with a current position indication. In one embodiment, a maximum map scale is determined which will result in a representation of the entire remainder of the route being shown within a visible map display area during travel along the route. In another embodiment, a map scale is set, and the map display is then controlled to maximise the amount of the remainder of the route which is shown within a visible map display area for the given map scale during travel along the route. | 04-24-2014 |

20090167224 | Motor Control Device and Motor-Driven Power Steering System Using the Same - An object of the present invention is to provide a motor control device capable of suppressing voltage composite vector fluctuation to increase the output of a brushless motor, and a motor-driven power steering system using this device. The present control device calculates motor phase current command values based on a target current and a rotor rotational position detection value, calculates voltage command values based on the motor phase current command values and phase current detection values, and supplies phase currents to a three-phase brushless motor based on the voltage command values. The present control device outputs the phase current command values so that the absolute value of a composite vector of respective phase drive voltages is substantially a value √3/2 times the power supply voltage. | 07-02-2009 |
