Abstract: A vehicle cruise control apparatus is provided. The vehicle has an engine 2 mounted thereon, a function of implementing constant-speed-cruise control and transmission control. The apparatus includes demand value computation section 14, engine control section 16, expected value computation section 12, compensation section 18 and AI-shift control section 20. The section 14 computes a demand value required for realizing a target speed. The section 16 adjusts an output of the engine 2 based on the demand value. The section 12 computes an expectation value based on the vehicle driving state and the driver's driving operation state. Based on a vehicle operating state including a comparison result of the demand value and the expectation value, the section 18 selects one of the demand value and the expectation value, and changes gears based on the selected value. As a result, driver's driving operation is prevented from becoming complicated during constant-speed-cruise control.

Abstract: A control target value calculation portion (42) calculates a control target value for an engine (32) based on a control instruction amount requested by a driver, which is calculated by a driver's instruction amount calculation portion (14), and control instruction amounts requested by control units such as a driver support amount calculation portion (16) and a wheel stability control amount calculation portion (18). A horsepower conversion portion (44) converts the control target value into a control target horsepower. Meanwhile, an allowable horsepower range calculation portion (40) calculates a target instruction horsepower and an allowable horsepower range based on the information from the driver's instruction amount calculation portion (14). Even when an integrated-control involving multiple control units is performed, a monitor portion (46) determines whether the control target derived through conversion is within the allowable horsepower range.

Abstract: A control device of a vehicle which switches a lockup clutch to an operating state depending upon vehicle conditions determines switching of the lockup clutch from lockup-ON switching lines established when the lockup clutch is in an engaged state, or from lockup-OFF switching lines established when the lockup clutch is in a released state. When switching of the lockup clutch is determined based on one of the lockup-ON switching lines and the lockup-OFF switching lines, a determination based on the other switching lines is selected as an effective determination about switching once the same switching of the operating state as that determined based on the above-indicated one of the switching lines is determined based on the other switching lines.
