VEHICLE SPEED CONTROL SYSTEM
First Claim
1. A speed control system operable to control a motor vehicle to operate in accordance with a set-speed value, the control system being operable to allow a user to reduce the set-speed value by actuation of a vehicle brake control member and/or to allow a user to increase the set-speed value by actuation of a vehicle accelerator control member, the system being further operable to compensate for an increase in brake torque applied when the user actuates the brake control member to reduce the value of vehicle set-speed by causing application of increased drive torque to one or more wheels of the vehicle and/or to compensate for an increase in powertrain torque applied when the user actuates the accelerator control member to increase the value of vehicle set-speed by causing application of increased brake torque to one or more wheels of the vehicle in proportion to the increase in powertrain torque.

28. A vehicle comprising a speed control system operable to control said motor vehicle to operate in accordance with a set-speed value, the control system being operable to allow a user to reduce the set-speed value by actuation of a vehicle brake control member and/or to allow a user to increase the set-speed value by actuation of a vehicle accelerator control member, the system being further operable to compensate for an increase in brake torque applied when the user actuates the brake control member to reduce the value of vehicle set-speed by causing application of increased drive torque to one or more wheels of the vehicle and/or to compensate for an increase in powertrain torque applied when the user actuates the accelerator control member to increase the value of vehicle set-speed by causing application of increased brake torque to one or more wheels of the vehicle in proportion to the increase in powertrain torque.

29. A method of controlling speed of a motor vehicle comprising causing the vehicle to operate in accordance with a set-speed value, the method comprising allowing a user to reduce the set-speed value by actuation of a vehicle brake control member and/or allowing a user to increase in the set-speed value by actuation of a vehicle accelerator control member, the method further comprising compensating for an increase in brake torque applied when the user actuates the brake control member to reduce the value of vehicle set-speed by causing application of increased drive torque to one or more wheels of the vehicle and/or compensating for an increase in powertrain torque applied when the user actuates the accelerator control member to increase the value of vehicle set-speed by causing application of increased brake torque to one or more wheels of the vehicle in proportion to the increase in powertrain torque.
