Vehicle speed control

Abstract

Aspects and embodiments of the invention relate to a speed control system (5) for a vehicle (1), the speed control system (5) comprising one or more processors (15) collectively configured to: receive a signal indicative of a vehicle speed (27); receive a 5 signal indicative of a driving surface gradient (31); receive a signal indicative of at least one vehicle body acceleration component (23); determine a score (59) in dependence on the at least one vehicle body acceleration component (23); determine a score difference (101) between the score (59) and a predefined score target (97); determine a target value for vehicle acceleration using a predefined relationship between (i) the 10 score difference (101), (ii) the vehicle speed (27) and / or the driving surface gradient (31), and (iii) vehicle acceleration; and generate a vehicle acceleration request (37) based on the determined target value for vehicle acceleration. Further aspects and embodiments of the invention relate to a system (3) and a vehicle (1) comprising the speed control system (5). Further aspects and embodiments of the invention relate to 15 a corresponding method (400) of controlling a speed of a vehicle (1) and computer- readable instructions (19) arranged to perform the method (400).
