Control system and method of controlling a driveline

A controller configured to control a driveline of a motor vehicle to operate in a first configuration in which the driveline is configured such that a first group of one or more wheels and in addition a second group of one or more wheels are arranged to be driven or a second configuration in which the first group of one or more wheels and not the second group of one or more wheels are arranged to be driven,

• the controller being configured to:
• determine whether a first set of one or more conditions have been met,
• determine whether a second set of one or more conditions have been met,
• cause the driveline to operate in the first configuration and not the second configuration when one of the first set of one or more conditions are met, and
• override operation in the first configuration and cause the driveline to operate in the second configuration and not the first configuration if the second set of one or more conditions have been met,
• wherein the second set of one or more conditions comprises that the vehicle is undertaking a parking maneuver on a surface having a surface coefficient of friction exceeding a predetermined value.

A method of controlling a driveline of a motor vehicle to operate in a selected one of a first configuration in which the driveline is configured such that a first group of one or more wheels and in addition a second group of one or more wheels are arranged to be driven or a second configuration in which the first group of one or more wheels and not the second group of one or more wheels are arranged to be driven,

• the method comprising:
• determining whether a first set of one or more conditions have been met;
• determining whether a second set of one or more conditions have been met;
• causing the driveline to operate in the first configuration and not the second configuration when one of the first set of one or more conditions are met;
• and
• overriding operation in the first configuration to cause the driveline to operate in the second configuration and not the first configuration if the second set of one or more conditions have been met,
• wherein the second set of one or more conditions comprises that the vehicle is undertaking a parking maneuver on a surface having a surface coefficient of friction exceeding a predetermined value.
