SECONDARY BRAKE SYSTEM FUNCTIONALITY

A computer-implemented method is disclosed, which is suitable for a vehicle comprising a primary brake system and a secondary brake system, wherein each of the primary and secondary brake systems is configured to control one or more brake actuators of the vehicle.The method comprises enabling the secondary brake system, triggering braking control by the secondary brake system, and obtaining measurements of an output of the secondary brake system, wherein the output is for control of the one or more brake actuators, and wherein the measurements are indicative of a response of the secondary brake system to the triggered braking control. The method also comprises determining a functionality of the secondary brake system by comparing the measurements of the output of the secondary brake system to a corresponding output of the primary brake system.Corresponding computer system, vehicle, computer program product, and non-transitory computer-readable storage medium are also disclosed.
