Failure warning for a vehicle information processing system
First Claim
1. A failure warning means for a vehicle wheel rotation control system including:
- a wheel rotation control section for processing wheel rotation information signals and providing wheel rotation control signals;
a speedometer;
a speedometer power line for supplying a driving voltage to the speedometer to give a speedometer reading;
wherein the speedometer power line connects the speedometer and a point in the wheel rotation control section such that the speedometer driving voltage derives from signals in the wheel rotation control section so that failure of the control section produces a null speedometer reading.

Abstract
A failure warning system for a wheeled vehicle which has an information processor for processing wheel rotation information. The system is applicable to a vehicle having an anti-skid or brake anti-lock device and which also has a bar light speedometer display. The power supply for the display derives from a point in the processor which is live at all times when the processor is functioning normally. Malfunction in the processor which causes loss of processor signal results in a null speedometer reading. A failure warning is thereby provided with a minimum of additional hardware which permits a minimum of difficulty in failure detection in the processor.
