Abstract
A method for operation of a reference-speed-regulating cruise control and a reference-speed-regulating cruise control which demands from a vehicle engine system a reference speed vref which may differ from a chosen set speed vset. Adjustment of at least the set speed vset is allowed if the reference speed vref differs from the set speed vset, which adjustment is based at least partly on a current speed vpres of the vehicle and on input from a user of the reference-speed-regulating cruise control. Quick and simple user-controlled adjustment of the set speed vset is thus achieved.
Claims11
A method for a reference-speed-regulating cruise control which outputs a reference speed vref to an engine of a vehicle to control said engine of said vehicle, said reference speed vref being such that it will not always be equal to a set speed vset input to said reference-speed-regulating cruise control, said reference speed vref being such it may be set by the reference-speed-regulating cruise control without any input from a user of said reference-speed-regulating cruise control, the method comprising adjusting at least said set speed vset when said reference speed vref differs from said set speed vset, and basing said adjustment at least partly on a current speed vpres of said vehicle and on input from a user of said reference-speed-regulating cruise control, said input from said user of said reference-speed-regulating cruise control causing said adjustment of said set speed vset to occur, without switching off said reference-speed-regulating cruise control, said input from said user of said reference-speed-regulating cruise control causing a first adjustment of said set speed vset when said reference speed vref is lower than said set speed vset, said first adjustment of said set speed vset being different than a second adjustment of said set speed vset, said input from said user of said reference-speed-regulating cruise control causing said second adjustment of said set speed vset when said reference speed vref is higher than said set speed vset.
A reference-speed-regulating cruise control configured to output a reference speed vref to an engine of a vehicle to control said engine of said vehicle, said reference speed vref being such that it will not always be equal to a set speed vset input to said reference-speed-regulating cruise control, said reference speed vref being such that it may be set by the reference-speed-regulating cruise control without any input from a user of said reference-speed-regulating cruise control, said reference-speed-regulating cruise control comprising an adjusting unit configured to adjust at least said set speed vset when said reference speed Vref differs from said set speed vset, and to base said adjustment at least partly on a current speed vpres of said vehicle and on input from a user of said reference-speed-regulating cruise control, said input from said user of said reference-speed-regulating cruise control causing said adjustment of said set speed vset to occur, without switching off said reference-speed-regulating cruise control, said input from said user of said reference-speed-regulating cruise control causing a first adjustment of said set speed vset when said reference speed vref is lower than said set speed vset, said first adjustment of said set speed vset being different than a second adjustment of said set speed vset, said input from said user of said reference-speed-regulating cruise control causing said second adjustment of said set speed vset when said reference speed vref is higher than said set speed vset.
