TLDR
In this paper, a process and arrangement designed, through braking, to keep constant the speed of a motor-vehicle when travelling on downhill slopes is described, with the aim of producing simple actuation and deactivation of the constant speedkeeping function.Abstract:
The invention relates to a process and arrangement designed, through
braking, to keep constant the speed of a motor-vehicle when travelling on
downhill slopes. With the aim of producing simple actuation and
deactuation of the constant speedkeeping function, the invention is
characterized principally in that the constant speedkeeping function
commences upon actuation of a driver-activated brake control (17). In
connection with this, the lowest vehicle speed is stored as a target value
within the memory of a control unit (1). The actual vehicle speed is then
regulated towards the target value through activation of the vehicle brakes
(4). Only once an ordinary driver-activated control (19) is activated, is the
specified regulation towards the target value suspended.read more

Heiko Claussen,Jurgen Eickhoff +1 more
TL;DR: In this paper, a process for controlling the speed of a vehicle travelling on a slope is described, where the vehicle is equipped with an electronic system which, through active brake intervention, adjusts the vehicle to a predetermined constant hill descent speed upon actuation of a hill descent control mode.
Patent
Adjustment of operating conditions of retarder braking stage on vehicle
TL;DR: In this article, a process for regulating the states of operation of a retarder (25) in a vehicle having a gas pedal and a brake pedal was described. But this process was restricted to a single vehicle and at least one gas pedal signal was recorded.
Patent
Method for controlling vehicle speed
TL;DR: In this paper, the authors propose a dynamic approach for controlling and regulating the vehicle speed in combination with a Bremsomat and/or a cruise control device, where the cruise control set speed is changed dynamically.
