A condition-based maintenance method is provided for a primary electrical system of a vehicle. The method includes obtaining a plurality of expected parametric values representing a state-of-health (SOH) of the primary electrical system of the vehicle; starting a series of operations to exercise a plurality of operating modes of the vehicle; continuously reading a plurality of voltage values from a battery voltage output of a diagnostic connector of the vehicle, performing analysis on the plurality of voltages values to generate current parametric values of SOH of the primary electrical system; based on comparison between the expected parametric values and the current parametric values, determining whether a condition-based maintenance is required; and, after determining that a condition-based maintenance is required, present a maintenance alert to an operator of the vehicle.

Condition based maintenance (CBM) of a vehicle primary electrical system

The present invention is an electronically controlled battery contactor that opens (disconnects) or closes (connects) the battery circuit from the other parts of a motor vehicle electrical system based on measured or sensed data derived from monitoring the electrical system, communicating with other on-board control units, and pre-programmed requirements specific to the vehicle operation. The primary functions are to protect the battery from excessive current drain when the vehicle is parked, protect against short circuits across the main electrical feed, and provide emergency disconnect for vehicle impact, rollover or sensed thermal events. A programmed delay function controls the opening of the contactor in conjunction with other electronic control units that may require electrical power for a period of time after vehicle shutdown. A master electrical disconnect switch is provided for manual override for servicing the vehicle or during an emergency.

Intelligent battery disconnect

An engine-powered vehicle includes an engine, a battery corresponding to a battery voltage, a starter, an alternator, a plurality of switchable electrical loads, a key switch configured to control the switchable electrical loads and corresponding to a key voltage, and an electrical system health monitor (ESHM) controller. The ESHM controller is configured to monitor a plurality of voltages, to determine an operating state based on the plurality of voltages, and to determine whether an operating state is a valid operating state or a fault state. The ESHM controller is configured to set a fault alert for vehicle maintenance when the operating state is a fault state and, when the operating state is a valid operating state, to monitor a predetermined set of input parameters corresponding to the operating state, to detect certain anomalies based voltage waveforms of the plurality of voltages, and to perform a corrective action based on the anomalies.

Electrical system health monitor (ESHM) system and method

This invention provides fire prevention and detection for heavy-duty and medium-duty commercial and military vehicles by ensuring the engine is automatically and immediately shut down upon the occurrence of a catastrophic event that may lead to a fire. The shutdown is achieved through the isolation of the vehicle batteries and alternator and the disconnecting of those devices from all electrical circuits. Anomalies that cause the shutdown and disconnect include battery and vehicle load currents that are outside a preset range, excessive temperatures, detection of smoke in the drive compartment or sleeper, or detection of a frontal impact accident or vehicle rollover. Once disconnected, the battery contactor must be manually reset in order to restore electrical power to the vehicle.

Vehicle fire prevention and detection system

A hybrid braking system that operates in conjunction with a foundation braking system, whether an air, hydraulic, electric, mechanical or electric braking system. Recovered energy is returned to the axle wheels in a controlled manner while the vehicle is in motion and certain criteria are met so as to compensate for aerodynamic drag and rolling resistance for instance but not at a rate to accelerate or launch a vehicle.
