Method and control arrangement for controlling a vehicle during a downhill start

A control arrangement for controlling a vehicle during a downhill start, the vehicle comprising an electric machine configured to propel and/or brake the vehicle and a brake system configured to apply a brake force to the vehicle, the control arrangement being configured to, following a detection of a downhill start indication, when the vehicle is maintained stationary on an inclined road section by means of a brake force applied by a brake system:

• control the electric machine to apply a brake torque while controlling the brake system to release the applied force;
• and
• control the electric machine to gradually decrease the applied brake torque so as to control the acceleration of the vehicle when set in motion in a downhill direction on the inclined road section.

A computer program product comprising computer program code stored on a non-transitory computer-readable medium, said computer program product used for a control arrangement for controlling a vehicle during a downhill start, the vehicle comprising an electric machine configured to propel and/or brake the vehicle and a brake system configured to apply a brake force to the vehicle, said computer program code comprising computer instructions to cause one or more control units to perform the following operations, following a detection of a downhill start indication, when the vehicle is maintained stationary on an inclined road section by means of a brake force applied by a brake system:

• control the electric machine to apply a brake torque while controlling the brake system to release the applied force;
• and
• control the electric machine to gradually decrease the applied brake torque so as to control the acceleration of the vehicle when set in motion in a downhill direction on the inclined road section.
