    摘要: Disclosed are an apparatus and a method for the adjustment time for IQ offset of a quadrature modulator of a transmission circuit. In adjusting the I-offset and the Q-offset of a quadrature modulator, supplied with an I-signal and a Q-signal output from an analog baseband unit to modulate a carrier. Set-up values of the I-offset and the Q-offset, associated with at least three different points on an IQ offset correction plane having an I-component and a Q-component as X- and Y-coordinates, are set for the analog baseband unit at respective different set-up timings. The values of the carrier leak level, associated with three-point offset set-up values of the output signal of the quadrature modulator, are acquired by a sole measurement operation. From the measured values of the three-point carrier leak levels, the values of the carrier suppression ratio for the three points are found from the measured values of the three points of the carrier leak level to find the optimum set-up values of the I-offset and the Q-offset.

    摘要: An apparatus is provided for controlling acceleration of a vehicle to a target acceleration. In the apparatus, a target acceleration calculator calculates the target acceleration. A provisional acceleration setting unit sets a provisional target acceleration such that a change rate of the provisional target acceleration is limited to a target limitation value. The provisional target acceleration is used during a step during which the acceleration of the vehicle is changed to the target acceleration. A drive power calculator calculates a drive power to obtain the provisional target acceleration. In the provisional acceleration setting unit, an initial value of the provisional target acceleration depends on a running state of the vehicle.

    摘要: A control apparatus controlling anteroposterior acceleration of a vehicle by controlling a motive power generation apparatus mounted on the vehicle, which is also provided with a staged transmission apparatus that operates on gear ratios. The motive power generation apparatus has an output shaft producing a rotation force in response to a command to be requested. The rotation force is transmitted to the drive wheels via the staged transmission apparatus. A feedback manipulated variable is calculated to control the production of the rotation force of the motive power generation apparatus so that an actual value of anteroposterior acceleration of the vehicle is controlled at a target value thereof. The calculated feedback manipulated variable is used as the command. When the staged transmission apparatus is in the switchover control of the gear ratios, the manipulated variable is is limited from being calculated (for example, stopped from being calculated).

    摘要: A running control apparatus calculates a target driving or braking torque in a calculating block to control the vehicle driven or braked by this torque at a target speed against a running resistance changed with running circumstances of the vehicle. In a control block, when a driver-required braking torque based on the braking operation of the driver is smaller than the target braking torque, the running control for the vehicle is performed to brake the vehicle by the target braking torque. When the driver-required braking torque becomes higher than the target braking torque, the running control is stopped, and the driver manually brakes the vehicle by the driver-required braking torque. When the driver-required braking torque is decreased to be lower than the target braking torque or a predetermined braking torque corresponding to the release of the braking operation, the running control is restarted.
