Module and method pertaining to mode choice when determining reference values
First Claim
1. A vehicle speed regulator module configured to control a speed of a vehicle based on at least one reference value, such that such the at least one reference value differs from a value corresponding to the speed indicated by a driver of the vehicle, the module comprising:
- a mode selection input unit configured to receive a mode choice from at least two selectable driving modes, each driving mode comprising a setting that influences a calculation of the at least one reference value;
a reference value calculation unit configured;
to make a first prediction and a second prediction of the speed along an itinerary, said first prediction based on an engine torque which retards the vehicle as compared with the speed regulator in which the reference value equals the speed indicated by the driver, and said second prediction based on an engine torque which accelerates the vehicle as compared with the speed regulator in which the reference value equals the speed indicated by the driver;
to compare said first prediction and the second prediction, respectively, with a lower limit value and/or an upper limit value, wherein the lower and upper limit values delineate a speed range within which the speed is maintained; and
to determine the at least one reference value based on the mode choice received and based on at least one of said comparisons and said first prediction and second prediction so that the at least one reference value is within the speed range bounded by the lower and upper limit values; and
the vehicle speed regulator module configured to regulate the speed of the vehicle based on the at least one reference value determined.

Abstract
A reference value for controlling a vehicle'"'"'s speed is obtained by: receiving a choice from two selectable driving modes, each driving mode having a unique set of settings that influence the calculation of the reference value; making a first prediction, based on an engine torque Tret that retards the vehicle as compared with conventional cruise control, and a second prediction based on an engine torque Tacc that accelerates the vehicle as compared with conventional cruise control; comparing the first and second predictions with a lower limit value and/or an upper limit value, which delineate a speed range within which the speed should be; and determining the reference value based on the mode choice and on at least one of the comparisons and said first prediction and second prediction of the speed along the horizon, such that the reference value is within the speed range.

11. A method of determining at least one reference value for a speed regulator that controls a speed of a vehicle such that said reference value that differs from a value corresponding to the speed indicated by a driver of the vehicle, the method comprising:
-
receiving a mode choice from at least two selectable driving modes, each mode choice comprising a setting that influences calculation of the at least one reference value; making a first prediction and a second prediction of the speed along an itinerary, said first prediction based on an engine torque which retards the vehicle as compared with speed regulator in which the reference value equals the speed indicated by the driver, and said second prediction based on an engine torque which accelerates the vehicle as compared with the speed regulator in which the reference value equals the speed indicated by the driver; comparing said first prediction and second prediction, respectively, with a lower limit value and/or an upper limit value, wherein the lower limit value and the upper limit value delineate a speed range within which the speed of the vehicle is maintained; determining, by an automated digital processor circuit, the at least one reference value based on said mode choice and on at least one of said comparisons and said first prediction and second prediction so that the at least one reference value is within the speed range bounded by the lower and upper limit values; and outputting the at least one reference value determined to a vehicle control system for controlling the speed of the vehicle. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A non-transitory computer-readable medium incorporating instructions configured, when the instructions are run on a computer, to regulate a speed of a vehicle based on at least one reference value that differs from a value corresponding to the speed indicated by a driver of the vehicle, by performing steps including:
-
receiving a mode choice from at least two selectable driving modes, each mode choice comprising a setting that influences calculation of the at least one reference value; making a first prediction and a second prediction of the speed along an itinerary, said first prediction based on an engine torque which retards the vehicle as compared with speed regulator in which the reference value equals the speed indicated by the driver, and said second prediction based on an engine torque which accelerates the vehicle as compared with the speed regulator in which the reference value equals the speed indicated by the driver; comparing said first prediction and second prediction, respectively, with a lower limit value and/or an upper limit value, wherein the lower limit value and the upper limit value delineate a speed range within which the speed of the vehicle is maintained; determining, by an automated digital processor circuit, the at least one reference value based on said mode choice and on at least one of said comparisons and said first prediction and second prediction so that the at least one reference value is within the speed range bounded by the lower and upper limit values; and regulating the speed of the vehicle based on the at least one reference value determined.
