Abstract

Cooling control systems described herein detect decreased operation of a cooling system of a vehicle, restrict movement of the vehicle without stopping movement responsive to decreased operation of the cooling system, and restrict movement of the vehicle by preventing the vehicle from traveling at a speed and/or power output for a non-zero designated period of time. This can allow for the vehicle to continue moving for a temporary period of time to avoid blocking traffic. Other control systems determine predicted distances and/or times that the vehicle can continue moving before coolant in the cooling system decreases below a designated threshold. Movement of the vehicle can be changed responsive to an upcoming distance and/or time that the vehicle is to travel exceeding the predicted distance and/or time. Other control systems modify a coolant flow rate based on differences between designated and ambient conditions.

Claims20

Dependent claims

A system comprising:

one or more processors configured to detect decreased operation of a cooling system of a vehicle while a propulsion system of the vehicle moves the vehicle, the one or more processors also configured to restrict movement of the vehicle without stopping the movement of the vehicle responsive to detecting the decreased operation of the cooling system,
wherein the one or more processors are configured to restrict the movement of the vehicle by preventing the vehicle from traveling at one or more of a speed or a power output for a non-zero designated period of time, wherein the one or more processors are configured to, following expiration of the designated period of time, determine during operation of the propulsion system whether the movement of the vehicle has stopped and, responsive to determining that the movement of the vehicle has stopped, the one or more processors are configured to determine whether one or more operational temperatures of the vehicle exceed one or more corresponding designated thresholds,
wherein the one or more processors are configured to prevent the vehicle from moving after the movement of the vehicle has stopped responsive to determining that the one or more operational temperatures exceed the one or more corresponding designated thresholds.

Dependencies are inferred from the claim text.
