VEHICLE INCLUDING MULTIPLE ANALOG SWITCH MONITORING SYSTEM WITH SIMULTANEOUS SWITCH-STATE DETECTION
First Claim
1. An automotive vehicle including a switch detection system, comprising:
- a hardware controller including a power supply that generates a supply voltage;
a first switch assembly including an input terminal that receives the supply voltage, the first switch assembly including a first switch that operates in a first plurality of switch states;
a second switch assembly connected in series with the first switch assembly and including an output terminal connected to a voltage reference point, the second switch assembly including a second switch that operates in a second plurality of switch states,wherein based on a voltage potential across the input terminal and the output terminal, the hardware controller determines the first plurality of switch states independently from the second plurality of switch states, and determines the second plurality of switch states independently from the first plurality of switch states.

Abstract
An automotive vehicle includes a switch detection system with a hardware controller having a power supply configured to generate a supply voltage. A first switch assembly includes an input terminal configured to receive the supply voltage. The first switch assembly includes a first switch configured to operate in a first plurality of switch states. A second switch assembly is connected in series with the first switch assembly and includes an output terminal connected to a voltage reference point. The second switch assembly includes a second switch configured to operate in a second plurality of switch states. Based on a voltage potential across the input terminal and the output terminal, the hardware controller determines the first plurality of switch states independently from the second plurality of switch states, and determines the second plurality of switch states independently from the first plurality of switch states.
