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 apparatus for controlling a continuously variable transmission for use with an automotive vehicle. The transmission is operable at a variable speed ratio for transmitting a drive from its input shaft to its output shaft. A target value for the speed of rotation of the input shaft of the transmission is calculated based on the sensed vehicle operating conditions including vehicle acceleration. A correction factor per predetermined unit time is calculated based on the sensed vehicle acceleration when the sensed vehicle acceleration exceeds a threshold value with the accelerator pedal released. The correction factor is added to the target input shaft speed value to correct the target input shaft speed value in an increasing direction at intervals of the predetermined unit time. The threshold value is decreased as the vehicle speed increases. The speed ratio is controlled to bring the input shaft speed into coincidence with the corrected target value.

摘要： An apparatus for controlling a continuously variable transmission for use with an automotive vehicle. The transmission is operable at a variable speed ratio for transmitting a drive from its input shaft to its output shaft. A target value for the speed of rotation of the input shaft of the transmission is calculated based on the sensed vehicle operating conditions including vehicle acceleration and vehicle speed. The target input shaft speed value is corrected to bring the vehicle acceleration into a predetermined range in the presence of the released accelerator pedal indicative signal. The speed ratio is controlled to bring the input shaft speed into coincidence with the corrected target input shaft speed value. The corrected target input shaft speed value is restricted below an upper limit set based on the vehicle speed.

摘要： A timing is detected according to which a vehicle accelerates from a fuel cut state, and a cylinder is detected in which combustion takes place immediately after this timing. A cylinder corresponding to a predetermined combustion order from the detected cylinder is then specified. By reducing the torque produced in the specified cylinder, forward/backward vibration of the vehicle due to variation of engine output torque during acceleration from coasting is suppressed.

摘要： A control unit (41) controls an opening of an exhaust recirculation valve (6) according to a running condition of a diesel engine (1). The control unit (41) calculates an equivalence ratio of the gas mixture supplied to the engine (1) and a target intake fresh air amount taking account of the air amount in the exhaust gas recirculated by the exhaust gas circulation valve (6), based on the opening of the valve (6) and a target excess air factor of the engine (1) set according to the running condition.
