An apparatus and a method for controlling an automotive vehicle are disclosed, in which a control amount for securing safety of the vehicle and the control amount for achieving a state intended for by the driver of the vehicle are switched in such a manner as to reduce the shock due to the change in the torque generated from the power train, thereby accomplishing both safety and maneuverability at the same time. A first target value is set for controlling at least selected one of the driving torque, the driving force and the acceleration/deceleration rate. A second target value is calculated in accordance with the drive mode intended for by the driver or the driving environment ahead of the vehicle. In the case where a deviation exceeding a predetermined value develops between the first target value and the second target value, the fluctuations of at least one of the driving torque, the driving force and the acceleration/deceleration rate are suppressed.

Automotive control apparatus and method

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.

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.

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).
