Abstract
Methods and systems are provided for operating a vehicle with a transmission. In one example approach, a method for a vehicle comprises, during a transmission shift having a first engine speed profile, adjusting a transmission shift indication provided to a vehicle operator based on a desired perceived shift time and a desired engine deceleration rate.
Claims18
A method for a vehicle comprising:
- shifting a transmission of the vehicle and during the transmission shift having a first engine speed profile, displaying a second engine speed profile to a vehicle operator, the second profile indicating a smaller inertia phase than the first engine speed profile;
- and
- before and after the transmission shift, applying a first filter to the first engine speed profile and during the transmission shift, applying a second filter to the second engine speed profile, where an amount of filtering of the second filter is less than an amount of filtering of the first filter;
- wherein the second engine speed profile is based on a desired perceived shift time and a desired engine deceleration rate and the first profile is an actual engine speed profile, where a duration of the inertia phase of the second engine speed profile is based on the desired perceived shift time and the desired perceived shift time is based on a driver selection.

A method for a vehicle, comprising:
- shifting a transmission of the vehicle;
- displaying an actual engine speed profile before and after the transmission shift, where a first filter is applied to the actual engine speed profile;
- and
- during the transmission shift having a first engine speed profile, displaying a second modified engine speed profile to a vehicle operator, wherein the second modified engine speed profile shows a faster rate of change of engine speed than the first engine speed profile, where a second filter is applied to the second modified engine speed profile and an amount of filtering of the second filter is less than an amount of filtering of the first filter;
- wherein the second modified engine speed profile shows a shorter duration of an inertia phase than the first engine speed profile wherein the duration of the inertia phase of the second modified engine speed profile is based on a desired perceived shift time determined based on a driver input and wherein the rate of change of the second modified engine speed profile is based on a desired engine deceleration rate.

A method for a vehicle, comprising:
- shifting a transmission of the vehicle;
- before and after the transmission shift, displaying an actual engine speed profile to a vehicle operator, where the displayed actual engine speed profile is filtered with a first filter;
- and
- during the transmission shift having a first engine speed profile, adjusting a transmission shift indication provided to the vehicle operator based on a desired perceived shift time and a desired engine deceleration rate, where the transmission shift indication includes a display of a modified engine speed profile, where the modified engine speed profile is modified from the first engine speed profile and filtered with a second filter, where an amount of filtering of the second filter is less than an amount of filtering of the first filter;
- wherein adjusting the transmission shift indication provided to the vehicle operator includes adjusting a duration of an inertia phase and a rate of change of the transmission shift indication, where the duration of the inertia phase is based on the desired perceived shift time which is based on a driver selection including one or more of a shift level position, a current pedal position, and vehicle speed, and further includes adjusting a transmission shift noise profile provided to the vehicle operator.
