Abstract
Embodiments of the present invention provide a vehicle having different operating modes, and for each such mode a different characteristic of output torque and accelerator pedal position. The rise of output torque in response to a propulsion request is more or less delayed according to the instant operating mode. The invention provides for blending of the response to a propulsion request so that the delay is progressively varied between a source and target operating mode.
Claims19
A method of blending between different filters of a propulsion request associated with the motor of a vehicle whereby a propulsion request is more delayed or less delayed according to the operating mode of the vehicle, the method comprising:
- detecting a current operating mode of the vehicle and applying a source filter appropriate to the current operating mode to a propulsion request,
- detecting a change of operating mode of the vehicle and selecting a target filter appropriate to the changed operating mode for a propulsion request, and
- blending from the source filter to the target filter over time so as to progressively change the delay applied to a propulsion request.
A control system for defining the propulsion applied to a vehicle by controlling blending between different filters of a propulsion request associated with a motor of a vehicle whereby a propulsion request is more delayed or less delayed according to the operating mode of the vehicle, said system being arranged to detect a current operating mode of the vehicle and apply a source filter appropriate to the current operating mode to a propulsion request, to detect a changed operating mode of the vehicle and select a target filter appropriate to the changed operating mode for a propulsion request, and to blend from the source filter to the target filter over time so as to progressively change the delay applied to a propulsion request.
