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 at least one vehicle body acceleration component (23); determine a sampling window having a window length (43) dependent on the vehicle speed (27); calculate a running average magnitude (45) of the at least one vehicle body acceleration component (23) over the determined sampling window; and generate a vehicle acceleration request (37) which depends on the running average magnitude 10 (45) of the at least one vehicle body acceleration component (23). 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 a corresponding method (200) of controlling a speed of a vehicle (1) and computer- readable instructions (19) arranged to perform the method (200). 15 FIG 3 VEHICLE SPEED CONTROL 5 10 15 FIG 3 20 26 20 12 66 19 F eb 2 02 6V E H I C L E S P E E D C O N T R O L 5 2 0 2 6 2 0 1 2 6 6 1 0 2 / 6 49 51 39 43 23 45’ 45 FIG 4 39 41 47 23 27 45 37 43 FIG 3 FIG 5 43 27 55 53 FIG 6 39C 41 57 23C 27 45C 43 39B 23B 45B 39A 23A 45A 47 37 59 61 59’ 9 DIE 41 27 43 068 23C 476139B 37 ,6S6S45B23B 23A FIG 5 5355 27 FIG 4 45' 43 45 49 6841 4327 43 4768 37 4523 20 26 20 12 66 19 F eb 2 02 6 4 1 2 7 4 3 0 6 8 4 5 C 2 3 C 4 7 6 1 5 7 3 9 B 3 7 5 9 4 5 B 2 3 B 4 5 A 2 3 A 5 3 5 5 4 5 ' 2 7 4 7 6 8 3 7 4 5 2 3
