A vehicle has an electric motor arranged to provide a driving torque, and a throttle or accelerator which can be set to a throttle angle θ or accelerator position, for example by the driver pressing on a pedal, wherein the electric motor is arranged to vary the driving torque according to the throttle position θ, such that at a particular angle or position, θ = θ0, the driving torque is set to zero, and wherein the zero torque point θ0 varies with the speed of the vehicle. The torque may approach a maximum torque at a maximum throttle position, and may approach a minimum torque, which may be negative, at a minimum throttle position. The system may be used with regenerative braking to provide negative torque, and to imitate in an electric or hybrid vehicle the driving experience of an internal combustion engine vehicle, in that lifting the accelerator pedal causes braking, but starting from rest the accelerator responds instantly. |
