摘要： A bus door/service brake interlock system having a warning system is provided. The interlock system includes a foot valve assembly to effect a service brake application when warning lights are activated, a vehicle door is open, and minimum speed conditions are met. An auxiliary line is positioned between a source of pressure and the foot valve assembly and includes a valve and a low pressure indicator. Should the operator leave the driver seat with the interlock system engaged, the parking brake is automatically applied.
