    摘要： A control system controls the output of a power source of a vehicle having a continuously variable transmission and a gear ratio to be set by the continuously variable transmission. The control system determines a target driving force (F) on the basis of an output demand and a vehicle speed, and determines a target output of the power source (P) for achieving the target driving force. The control system determines a target output speed preset for the target output, and controls the gear ratio of the continuously variable transmission (Step S4) so that the actual output speed of the power source may become the target output speed. The control system further determines the target output torque (To) of the power source on the basis of the target output and the actual output speed of the power source, and controls the power source to achieve the target output torque. When the gear ratio is to be changed, its changing rate is made different in at least two quick and slow states. Moreover, the target output speed is provided with an upper limit, which is changed.

    摘要： An integrated control system for both an electronically-controlled engine and a steplessly variable automatic transmission, comprises a speed-change ratio arithmetic processing section for calculating the speed-change ratio (Roi) as a ratio (Ni/No) of the transmission input speed (No) to the transmission output speed (No), a target driving torque arithmetic processing section (A) for retrieving a target driving torque (tTd), based on both the accelerator operating amount (APS) and the vehicle speed (VSP), from a first predetermined characteristic map, and a target speed-change ratio arithmetic processing section (B) for retrieving a target speed-change ratio (tRoi), based on both the accelerator operating amount (APS) and the vehicle speed (VSP), from a second predetermined characteristic map. Also provided is a target engine output torque arithmetic processing section (C) for calculating a target engine output torque (tTe), based on all of the target driving torque (tTd), the speed-change ratio (Roi), and a speed ratio (e) of the transmission input speed (Ni) to the engine speed (Ne). Depending on the engine speed (Ne) and the target engine output torque (tTe), the throttle opening (TPS) and the transmission input speed (Ni) are both feedback-controlled.

    摘要： An automatic transmission such as a continuously varia­ble transmission or an automatic transmission with a plurali­ty of gear positions is controlled using a target accelera­tion (Go) map which contains target accelerations correspon­ding to first indications (e.g., the amount (ϑ AP ) of depre­ssion of an accelerator pedal or the engine throttle opening) representative of the driver's intention for acceleration or deceleration and second indications representative of speeds of the motor vehicle. The target acceleration map is arran­ged such that when each of the second indications is constant, each of the target accelerations increases as the first indica­tion increases, at a rate which is greater if the first indica­tion is smaller. From such a target acceleration map, a target acceleration is determined on the basis of the actual values of the first and second indications at the time, and the speed reduction ratio of the automatic transmission is con­trolled so that the target acceleration is achieved. In the target acceleration map, cruising speeds of the motor vehicle vary linearly as the first indications vary.
