Abstract
Method and system may be configured to determine a stationary time period during which a vehicle has remained stationary. The method and system may be further configured to enable a parked function of the vehicle in response to determining that the stationary time period exceeds a designated threshold. While the parked function is enabled, the vehicle applies a braking effort to the vehicle in response to detecting movement of the vehicle.
Claims17
A system comprising:
- a controller configured to determine whether a vehicle system formed from a first vehicle and one or more additional vehicles has remained stationary for at least a stationary time period, the controller configured to determine whether the first vehicle is a lead vehicle of the vehicle system that sends commands to the one or more additional vehicles so that the lead vehicle and the one or more additional vehicles coordinate efforts in moving the vehicle system, the controller configured to enable a parked function of the vehicle system in response to determining that the vehicle system has remained stationary for at least the stationary time period and that the first vehicle is the lead vehicle, the controller configured to direct the vehicle system to apply a braking effort in response to detecting movement of the vehicle system while the parked function is enabled, wherein the controller is configured to disable the parked function of the vehicle system responsive to the first vehicle being switched from being the lead vehicle to at least one of the one or more additional vehicles being the lead vehicle.
A method comprising:
- determining whether a vehicle system formed from a first vehicle and one or more additional vehicles has remained stationary for at least a stationary time period;
- determining whether the first vehicle is a lead vehicle of the vehicle system that sends commands to the one or more additional vehicles so that the lead vehicle and the one or more additional vehicles coordinate efforts in moving the vehicle system;
- enabling a parked function of the vehicle system in response to determining that the vehicle system has remained stationary for at least the stationary time period and the first vehicle is the lead vehicle;
- applying a braking effort to the vehicle system in response to detecting movement of the vehicle system and while the parked function is enabled;
- and
- disabling the parked function of the vehicle system in response to the first vehicle being switched from being the lead vehicle to at least one of the one or more additional vehicles being the lead vehicle.
3 more elements
A system comprising:
- a controller configured to determine whether a first vehicle of a vehicle system is designated as a lead vehicle or a remote vehicle of the vehicle system, the vehicle system including the first vehicle and at least a second vehicle, the lead vehicle configured to dictate movements of the at least the second vehicle, the controller configured to determine whether the first vehicle is stopped and that an engine of the vehicle system is shut down, the controller configured to determine whether the first vehicle is stopped for at least a stationary time period, the controller configured to determine whether a position of a reverser device is in a designated position, and
- the controller is configured to enable a parked function of the first vehicle in response to determining that the first vehicle is designated as the lead vehicle, the first vehicle has been stopped for at least the stationary time period, and that the position of the reverser device is in the designated position, wherein the controller is configured to disable the parked function responsive to determining that the first vehicle is no longer designated as the lead vehicle.
