Abstract

Systems and methods are described for determining whether a platooning system is safe. In various aspects, a platooning system may collect information from various sensors included on one or more vehicles, and use the gathered information to determine whether the system achieves a threshold amount of safeness is achieved. In response to determining that a vehicle is unsafe, a system may prohibit vehicles from platooning or cause platooning vehicles to end their current platooning session.

First claim

What is claimed is:

1 . A method for determining whether to perform an adverse action, comprising:
establishing a wireless link between a first vehicle and a second vehicle, wherein information about the engine torque of the first vehicle and braking system of the first vehicle are transmitted to the second vehicle via the wireless link; determining a threshold safety level, wherein the threshold safety level is based at least in part on a gap size and determined by:
generating a first simulation scenario modeling vehicle behavior under a first set of assumptions,
generating a second simulation scenario modeling vehicle behavior under a second set of assumptions different from the first set of assumptions, and
analyzing outcomes of the first simulation scenario and the second simulation scenario to establish the threshold safety level; and
in response to the first vehicle or the second vehicle determining that a current safety level of the first vehicle and the second vehicle do not exceed the threshold safety level, performing the adverse action, wherein the threshold safety level comprises sufficient deceleration necessary to avoid a collision, at the first vehicle, as detected by both a platoon electronic control unit (PECU) and a brake electronic control unit (BECU) on the first vehicle.

2 . The method of claim 1 , wherein performing the adverse action comprises:
determining whether the first and second vehicle are engaged in a platoon; in response to the first vehicle and the second vehicle being engaged in the platoon, dissolving the platoon; and in response to the first and second vehicle not being engaged in the platoon, prohibiting the first vehicle and the second vehicle from platooning.

3 . The method of claim 2 , wherein the safety level is determined based at least in part on whether the first and second vehicles include ABS brakes, and the versions of the ABS brakes.

4 . The method of claim 2 , wherein the threshold safety level is determined by the platooning electronic controller (PECU), and wherein the PECU is configured to send commands to a braking ECU (BECU) and an engine ECU (EECU).

5 . The method of claim 4 , wherein the PECU is further configured to send commands to a transmission electronic controller (TECU).

6 . The method of claim 2 , wherein the threshold safety level is determined by the platooning electronic controller (PECU), and wherein the PECU is configured to at least in part control a braking ECU (BECU) and an engine ECU (EECU).
