Abstract
A method of controlling one or more vehicles of a platoon of vehicles includes determining in response to information of forward route conditions of the platoon an opportunity to mitigate braking losses, performing regenerative braking in response to a deceleration output of an cooperative adaptive cruise control (CACC) system, adjusting an inter-vehicle distance of the CACC system, and performing at least one of the regenerative braking and the adjusting the inter-vehicle distance.
Claims26
A method of controlling one or more vehicles of a platoon of vehicles, the method comprising:
- determining in response to information of forward route conditions of the platoon an opportunity to mitigate braking losses of at least one vehicle of the platoon by performing regenerative braking in response to a deceleration output of a cruise control system, and adjusting an inter-vehicle distance of the cruise control system;
- and
- performing the regenerative braking and the adjusting the inter-vehicle distance;
- wherein the determining the opportunity to mitigate braking losses includes iteratively evaluating a braking loss mitigation from the performing regenerative braking and the adjusting the inter-vehicle distance.
A system for controlling one or more vehicles of a platoon of vehicles, the system comprising:
- a communicative adaptive cruise control system including one or more processors configured to execute instructions stored on one or more non-transitory computer readable memory media to:
- receive information of forward route conditions of the platoon,
- determine in response to the information of forward route conditions an opportunity to mitigate braking losses of at least one vehicle of the platoon by regenerative braking and adjustment of an inter-vehicle distance of the platoon of vehicles, and
- perform the regenerative braking and the adjusting the inter-vehicle distance, and
- iteratively evaluate a braking loss mitigation from the performing the regenerative braking and the adjustment of the inter-vehicle distance.
An apparatus for controlling one or more vehicles of a platoon of vehicles, the apparatus comprising:
- one or more non-transitory computer readable memory media configured with instructions executable by one or more processors to perform a plurality of acts, including:
- receiving information of forward route conditions of the platoon,
- determining in response to the information of forward route conditions an opportunity to mitigate braking losses of at least one vehicle of the platoon by regenerative braking and adjustment an inter-vehicle distance of the platoon of vehicles,
- performing the regenerative braking and the adjusting the inter-vehicle distance, and
- iteratively evaluating a braking loss mitigation from the performing regenerative braking and the adjustment of the inter-vehicle distance.
