In one aspect of the invention there is provided a motor vehicle comprising drive means operable to provide motive power to the vehicle, the vehicle operable automatically to switch off and subsequently to restart the drive means during a drivecycle thereby to reduce a value of one or more prescribed operating parameters, wherein the vehicle may be placed in an eco-stop condition by driver-operated brake means in which the vehicle is held stationary and the drive means is off, the vehicle being operable automatically to restart the drive means when the driver signals release of the brake means, the vehicle comprising means for detecting departure of the driver from the vehicle, in the event that departure of the driver is detected when the vehicle is in the eco-stop condition the vehicle being arranged not to restart the drive means when the driver signals release of the brake means.

Vehicle and method of control thereof in start and stop condition

Embodiments of the invention provide a vehicle comprising actuator operable to provide motive power to the vehicle, the vehicle being operable automatically to switch off and subsequently to restart the actuator thereby to reduce an amount of time the actuator is on, wherein the vehicle may be placed in an eco-stop condition by a driver-operated brake in which the vehicle is held stationary and the actuator is off, the vehicle being operable automatically to perform an eco-start operation in which the actuator is restarted when the driver releases the brake, wherein when an eco-start is performed the vehicle is arranged automatically to be held stationary by the brake whilst the actuator is restarted, if the actuator fails to restart the vehicle being further arranged automatically to assume a failed start condition in which the vehicle continues to be held stationary.

Motor vehicle and method of control thereof

The present invention relates to a powertrain control system () for a motor vehicle. The vehicle comprises an internal combustion engine () and an adjustable suspension system () operable in accordance with first and second ride height settings, said settings being associated with respective first and second vehicle ride heights. The powertrain control system () comprises a stop/start controller () for issuing an engine stop request signal and an inhibitor () for inhibiting operation of the stop/start controller () in dependence on a selected ride height setting.

Powertrain control system

The present application relates to a powertrain control system () for a motor vehicle. The vehicle has an internal combustion engine () coupled to a transmission (). The transmission () is operable in a high range and a low range. The powertrain control system () has a stop/start controller () for issuing an engine stop request signal when one or more conditions have been met. An inhibitor () is also provided for inhibiting operation of the stop/start controller () when the low range is selected. The application also relates to a method of operating a motor vehicle power-train.
