A working fluid supply system is provided with: a first oil pump and a second oil pump driven by an engine; a switching valve configured to cause a discharge passage of the second oil pump to communicate with at least one of a supply passage and a first drain passage; and a controller configured to switch the switching valve. The controller is configured to switch the switching valve by spending a switching time that is set in accordance with a degree of pressure variation predicted to be caused in the supply passage when the switching valve is switched instantaneously.

A bracket for a hose of a vehicle system. The bracket having a hook and a mounting segment. The hook allows free movement of the hose while cradling the hose to prevent the hose from rubbing against abrasive or high temperature surfaces. The mounting segment includes an anti-rotation segment which abuts a mounting point to prevent rotation of the bracket. The bracket also includes gussets which reinforce the bending resistance of the bracket.

A multiply-redundant system that prevents a driver from starting and/or moving a vehicle if a compressed natural gas fill system is not correctly and completely disconnected from the vehicle. One or more sensors in combination with one or more optional microswitches combine to lock-out the vehicle's ignition or otherwise prevent it from starting and/or moving. For different levels of safety, different combinations of sensors can be used with the lowest level having a single proximity sensor sensing the presence or absence of a high-pressure fill hose. The highest level of safety being achieved by having separate proximity sensors on the fuel fill hose fitting, the gas cap cover and a manual safety valve along with a redundant microswitch. An optional override that may be restricted as to the number of times it can be used can allow starting with a faulty sensor in order to allow maintenance.

A fluid-distribution system for use with one or more vehicle sub-systems in a vehicle includes a first transfer conduit, a second transfer conduit, and a valve unit. The first transfer conduit defines a first interior space and is coupled to a fluid source to receive and direct a fluid through the first interior space. The second transfer conduit defines a second interior space and is spaced apart downstream from the first transfer conduit. The valve unit extends between and interconnects the first transfer conduit and the second transfer conduit.

In one embodiment, a method includes, by a computing system of a vehicle, determining a first temperature of a control unit of the vehicle, wherein the control unit and one or more components of the vehicle are interconnected through a thermal network, determining a thermal objective for the control unit based on the first temperature of the control unit, selecting, based on the thermal objective for the control unit, at least a first component from the one or more components, and sending one or more signals to one or more actuators within the thermal network to enable a heat-transfer fluid to flow between (1) a first portion of the thermal network thermally coupled to the control unit and (2) a second portion of the thermal network thermally coupled to the selected first component.
