DRIVING FORCE CONTROLLER FOR VEHICLE

摘要

PURPOSE:To always and surely realize operatability such as acceleration intended by a driver by correcting a slipping standard value of driving wheels to which drivig torque of an engine is transmitted via a transmission, by a larger correction value as a shift position detected by the transmission moves closer to the low-speed stage side. CONSTITUTION:Rotational speeds of respective driving wheels 2(L, R) in a vehicle are detected by respective wheel rotational speed sensors 6, 7, and these respective detection signals are inputted to the CPU 11 of a driving force control unit 8, and slipping conditions of the respective driving wheels 2L, 2R are detected. A slipping standard value of driving torque control of driving wheels 2 is set based on the detection signal of an accelerator opening sensor 14 by means of CPU 11. The driving torque of the engine is controlled via a fuel supply control unit 12 of respective cylinders 13-1-13-6, in response to the detection value and the standard value of the slipping, by utilizing the accelerator operation quantity and speed change shift position as parameters which display acceleration intention of a driver. In this case, the shift position of the transmission for transmitting the driving torque of the engine to the driving wheels 2L, 2R is detected. As a result, the standard value of the slipping is corrected by a larger correction quantity as the speed change ratio at the detected shift position is shifted closer to the low speed stage side.
