摘要:
A control apparatus is provided to control the stopping of a vehicle. The control apparatus comprises a speed detector that detects a speed of a vehicle, speed acquiring means, target setting means, and control means. The speed acquiring means acquires an actual speed of the vehicle from detected results of the speed detector. The target setting means sets a target acceleration of the vehicle depending on the actual speed when the vehicle is stopped automatically. The control means controls an actual acceleration of the vehicle at the target acceleration.

A vehicle speed control device calculates a desired axle torque for maintaining a speed of a vehicle to a set speed, and conducts cruise control. Specifically, the vehicle speed control device calculates a drive force including a feedforward component corresponding to the set speed and a travel resistance against the travel of the vehicle, and a feedback component corresponding to a deviation of the set speed from the actual speed of the vehicle as a desired axle torque. The vehicle speed control device interrupts the cruise control when a requested drive axle torque requested by an accelerator operation during the cruise control exceeds the desired axle torque, and restarts the cruise control when the requested drive axle torque becomes lower than the desired axle torque.

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.

An estimated gradient value of a road is calculated based on a vehicle acceleration “A” and a time varying portion “A′” of a wheel speed. In a case that an acceleration corresponding value “Ggrad0” for the estimated gradient value is not regarded as indicating an exact figure, due to influences of disturbances, the acceleration corresponding value “Ggrad0” is corrected by a limiting value for rate-of-change with regard to the road gradient depending on respective vehicle speed, and by a limiting value for the road gradient. As a result, the acceleration corresponding value “Ggrad” for the estimated gradient value can be more exactly obtained.

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.

In a cruise control system for a vehicle, a cruise ECU calculates a cornering resistance applied to the vehicle based upon a steering angle, when a vehicle turns. The cruise ECU calculates a speed reduction amount as a correction vehicle speed based upon the cornering resistance. The cruise ECU subtracts the correction vehicle speed from a set vehicle speed to set a target vehicle speed so that the vehicle speed becomes lower as the cornering resistance is larger. The cruise ECU controls the vehicle speed to be within a permissible speed range of the target vehicle speed.

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).

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.
