摘要:
A system and method for testing operation of that portion of a transportation vehicle's electrical system that has switches accessible for selective actuation by an occupant of an interior of the vehicle to control exterior lamps through an ESC (12). During a learn mode (56) of a test, processor apparatus executes a learn algorithm stored in the ESC and as the learn algorithm executes, a person inside the vehicle operates the switches in a desired sequence to cause the ESC to store data related to the sequence. During a playback mode (58) of the test, the processor apparatus executes a playback algorithm stored in the ESC to cause the ESC to actuate the lamps in accordance with the stored data. A defect in any portion of a lamp circuit is observed by failure of a lamp to illuminate in the stored sequence.
摘要:
A system and method for the automated sequencing of certain operations when a vehicle, such as a school bus, (10) approaches a railroad crossing where it is required to stop before proceeding across the crossing. A devoted switch (28) is actuated by the driver to initiate the sequence. After stopping, vehicle speed or distance traveled is used to restore conditions of various devices whose operation was affected by the initial switch actuation.
