Systems and methods for monitoring a state of charge of a battery are disclosed. An updated state of charge of the battery may be determined based on a measured terminal voltage of the battery, a measured current of the battery, and a value of at least one battery parameter selected from a plurality of values based on a prior state of charge of the battery.

Monitoring battery state of charge

Systems and methods for monitoring a state of health of a battery are disclosed. The state of health of the battery may be determined based on an internal resistance of the battery. The state of health of the battery may be determined based on a measured terminal voltage of the battery, a measured current of the battery, a temperature of the battery, and a state-of-charge of the battery.

System and method for monitoring a state of health of a battery system

A method of indirect tire pressure monitoring for indicating when a pneumatic tire on a wheel at one end of a motor vehicle axle is underpressurized relative to a pneumatic tire on a wheel at an opposite end of the axle while the vehicle is being driven on a road surface. ABS wheel sensors are used as inputs to a devoted processor for indirect tire pressure monitoring.

System and method for indirect indication of tire pressure loss

Redundant power supplies and redundant channels of communication maximize the probability that a controller will trigger a battery disconnect switch to open when commanded to do so.

Methods and circuits for controlling a battery disconnect switch

Systems and methods for monitoring catalyst presence, reverse and damage in an aftertreatment device. The disclosed systems and methods involve calculating the heat capacity of the catalyst device based on information received from sensors for measuring temperatures at the inlet and outlet of the SCR device and the exhaust mass flow.

Systems and methods for monitoring catalyst device integrity

A geofence system which locates a position as within or without the complex polygon type geofence using a simplified algorithm. The algorithm obtains a position and compares it to the polygon by establishing a ray from the position constructed in a cardinal direction of the coordinate system. The 'polarity' of the count of intersections between the ray and geofence indicates whether the position is inside the geofence or not.
