Patent number: 10647320Abstract: A device and a method for controlling vehicle speed in a vehicle equipped with cruise control while traveling downhill. The method involves driving a vehicle downhill with the cruise control set to a brake speed; detecting a current vehicle speed; applying the auxiliary brake to maintain the brake speed; detecting a request for a downshift from a current gear to a lower gear; and determining if a downshift is permissible at the current speed. If a downshift is not permissible, then a control unit automatically applies the service brakes to retard the vehicle speed; retarding the vehicle from a current speed to a lower speed at which a downshift to a lower gear is permissible; and performing a downshift to a lower gear when the second vehicle speed is reached. The cruise control is set to a second brake speed lower than the first brake speed.Type: GrantFiled: August 28, 2015Date of Patent: May 12, 2020Assignee: VOLVO TRUCK CORPORATIONInventors: Tobias Carlsson, Anders Eriksson, Lars Karlsson, Henrik Andersson

Patent number: 10569775Abstract: A cruise control arrangement is provided with a cruise control speed function and where the cruise control arrangement is provided with a set cruise speed value and a set brake cruise speed value, and where the cruise control brake function is active when the vehicle travels downhill, where the cruise control arrangement is adapted to activate at least one auxiliary brake when the vehicle speed reaches the set brake cruise speed, to apply a service brake of the vehicle in order to reduce the speed of the vehicle to a predefined first speed if the vehicle speed exceeds the set brake cruise speed when the least one auxiliary brake is delivering full brake power, where the predefined first speed is lower than the set brake cruise speed. Undesired acceleration during downhill travel can be avoided when the brake power of the auxiliary brake is not sufficient. Further, a required downshift can be delayed, which will improve the fuel consumption of the vehicle.Type: GrantFiled: June 27, 2014Date of Patent: February 25, 2020Assignee: VOLVO TRUCK CORPORATIONInventors: Lars Karlsson, Anders Eriksson
