A hybrid drive system for a vehicle 3, includes an engine 2, a drive motor 3, an energy storage device 7 for powering the motor, a driver operable accelerator control 10 moveable from a zero to a maximum position to control the drive system and an arrangement 11 for increasing movement resistance at a position or positions to divide control travel, such as pedal travel, into two or more parts. A controller 8 controls the engine 2 and motor 3 in dependence on the position of the driver's control 10. A respective different mode of drive operation is provided when the accelerator control is in each part of its travel. Different modes of operation for acceleration from rest may be provided, including a drive motor only eco mode, a max mode where both the engine and motor are employed to obtain maximum acceleration and an intermediate standard mode where output of the internal combustion engine is limited in order to reduce fuel consumption. A driver can select a desired mode of operation by feeling resistance in movement of the accelerator control 10. |
