Abstract
A cruise control arrangement for a vehicle includes a cruise control speed function, a cruise control brake function and at least one selectable economy level, having a set maximum speed value corresponding to a maximum allowed vehicle speed, a set brake speed value corresponding to a brake cruise speed and a set cruise speed value corresponding to a cruise speed, where a temporary brake speed value replaces the set brake speed value as the actually used brake speed value, and where the temporary brake speed value is dependent on the selected economy level. The behaviour of the cruise control of a vehicle can be adapted to take account of economy, which makes it possible to optimize the fuel consumption of the vehicle.
Claims16
A cruise control arrangement for a vehicle, where the cruise control arrangement is provided with a cruise control speed function, a cruise control brake function and at least one selectable economy level, where the arrangement has a set maximum speed value corresponding to a maximum allowed vehicle speed, a set brake speed value corresponding to a brake cruise speed and a set cruise speed value corresponding to a cruise speed, wherein a temporary brake speed value replaces the set brake speed value as the actually used brake speed value when an economy level is selected, where the temporary brake speed value is dependent on the selected economy level.
A method for changing the temporary brake speed value in a cruise control arrangement for a vehicle comprising a cruise control speed function, a cruise control brake function and at least one selectable economy level, having a set maximum speed value, a set brake speed value and a set cruise speed value, comprising:
- adding an offset speed value corresponding to a selected economy level to the set brake speed value,
- using the sum of the offset speed value and the set brake speed value as a temporary brake speed value.
