Vehicle propulsion torque control systems and methods

A vehicle propulsion system configured to generate wheel torque includes an engine arranged to output a first propulsion torque to a transmission and an electric motor arranged to output a second propulsion torque downstream of the transmission. The vehicle propulsion system also includes a controller programmed to, in response to detecting a lash crossing associated with one of the electric motor and the transmission, set a torque slew rate of the other one of the electric motor and transmission such that each of the electric motor and transmission undergoes lash crossings at different points in time.

Method of controlling gear shift for hybrid vehicle including dual clutch transmission

A method of controlling gear shift for a hybrid vehicle with a dual clutch transmission (DCT) may include making a request for reduction in transmission input torque at a time point of entrance into down shift to a first stage from a second stage, determining whether the vehicle is accelerated via manipulation of an accelerator pedal during the down shift, and controlling to begin to gradually reduce an transmission input torque reduction request amount in a torque phase period in which clutch torque is exchanged after a first-stage gear is engaged upon determining that the vehicle is accelerated during the gear shift.

Vehicle driving-torque control device

A vehicular driving torque control apparatus, comprising: a limitation variation rate setting section included in a driving torque control section and configured to set, in a form of a limitation variation rate, a low torque side limitation variation rate used in a low torque side until the target driving torque reaches to a torque variation rate switching threshold value and a high torque side limitation variation rate used in a high torque side exceeding the torque variation rate switching threshold value and to execute a limitation suppression variation rate setting process in which the low torque side limitation variation rate is set to be larger than the high torque side limitation variation rate until the target driving torque reaches to the torque variation rate switching threshold value.
