摘要： An input torque limiting device for an infinitely variable transmission connected to an engine, wherein the transmission can vary a speed ratio up to infinity. In the input torque limiting device, the maximum torque which can be input is computed according to the output/input speed ratio which is an inverse of the speed ratio, without adversely affecting the durability and performance of the infinitely variable transmission, and the engine torque is controlled not to exceed the maximum torque. In this way, in the infinitely variable transmission, input of an excessive torque when the speed ratio is in the vicinity of infinity is prevented.

摘要： A driving force control system for an automotive vehicle comprises a vehicle speed sensor detecting an operating parameter indicative of a speed of the vehicle and generating a vehicle speed signal indicative of said detected operating parameter. An ordinary target driving force generator determines an ordinary target driving force in response to operator manipulation of the accelerator pedal and the vehicle speed. The ordinary target driving force is a predetermined target value of driving force required to keep the vehicle rolling over the surface of a flat road that has 0% gradient. A running resistance increment generator determines an increment in running resistance from a standard resistance that is indicated by the ordinary target driving force. A corrected target driving force generator receives the ordinary target driving force, the vehicle speed and the running resistance increment. It determines corrected target driving force. The corrected target driving force generator keeps setting the ordinary target driving force as the corrected target driving force when the vehicle speed signal is low.

摘要： An IVT controller determines whether the operation mode of an infinitely variable transmission (IVT) is a power recirculation mode or a CVT direct mode, and selects an inertial torque computing equation corresponding to the operation mode. The inertia torque accompanying a speed change of the IVT is computed using the computing equation. An engine controller adjusts the opening of an electronic control throttle, and adjusts the torque of the engine so that computed inertia torque is eliminated.

摘要： In a vehicle equipped with a continuously variable transmission, sensors detect a vehicle speed, an accelerator depression degree and an output rotation speed of the transmission. The minimum required drive shaft drive torque is calculated from the vehicle speed and the accelerator depression degree. A target input rotation speed of the transmission for achieving the minimum required drive shaft drive torque with the least engine fuel consumption is calculated according to the vehicle speed. The input rotation speed is controlled to this target input rotation speed. The target engine output torque to generate the minimum required drive shaft drive torque is calculated, and an engine throttle opening is controlled to obtain this torque. As a result, the required vehicle drive force is obtained with the minimum engine fuel consumption.

摘要： An ordinary target driving force is generated against a detected value of the vehicle operator depression of an accelerator pedal and a detected value of the vehicle speed. The ordinary target driving force is a driving force required to keep the vehicle rolling on a flat horizontal road at the detected value of vehicle speed with the detected value of the vehicle operator depression of the accelerator pedal. A running resistance increment, i.e., an increase of running resistance from a standard running resistance, is calculated. A preliminary driving force correction is determined in response to the running resistance increment. The preliminary driving force correction is subjected to variation. The preceding old value of a driving force correction is subtracted from a current value of the preliminary driving force to give a variation in driving force correction. This variation is limited to fall in a range between an upper and a lower limit to give a limited driving force correction variation. The preceding old value of the driving force correction is added to the limited driving force correction variation to give the driving force correction. This driving force correction is added to the ordinary target driving force to give a corrected target driving force. To realize the corrected target driving force, engine torque and CVT ratio are adjusted.

摘要： A driving force control system for an automotive vehicle comprises a controller. The controller determines standard resistance (RLDTRQ) in response to vehicle speed (VSP), and it also determines an increment in running resistance (RESTRQ) from the standard resistance (RLDTRQ). The controller determines driving force correction (ADDFD) in response to the increment in running resistance (RESTRQ). The controller adds the driving force correction (ADDFD) to ordinary target driving force (tTd#n) to provide corrected target driving force (tTd). The controller converts the increment in running resistance (RESTRQ) into the driving force correction (ADDFD) at a rate that is variable in response to the increment in running resistance (RESTRQ).

摘要： An engine control system for an internal combustion engine of a type having a stratified combustion mode and a homogeneous combustion mode comprises a controller for controlling an EGR flow in the engine with an EGR control valve. The controller effects a changeover of an EGR control mode of the EGR control valve from a first EGR mode to a second EGR mode immediately in response to a changeover request signal before an actual changeover of a combustion control mode from the stratified combustion mode to the homogeneous combustion mode. In the case of a changeover from the homogeneous mode to the stratified mode, the controller effects a changeover of the EGR control mode from the second EGR mode to the first EGR mode in response to an actual changeover of the combustion control mode, with a delay after the changeover request signal.
