Embodiment Construction

[0014] Referring to the drawings, wherein like numerals represent like or corresponding parts throughout the several views, figure 1 is for electric / hybrid vehicles (in figure 1 Not shown in ), a functional block diagram of a vehicle system 110 and a vehicle controller 100 including embodiments of the method and system of the present invention. A vehicle controller 100 , such as a vehicle control module, electronic control module, or other control module, receives inputs (such as passenger inputs) and provides commands and communications between many vehicle systems. Vehicle controller 100 communicates with vehicle systems 110 , such as for a propulsion system, emissions system, air management system, or other vehicle systems. The vehicle system 110 may include various controllers, modules, actuators, and devices as necessary to provide a particular system. The vehicle system 110 includes a power module 120 for connecting and providing power to system components 150, includi...

Abstract

Systems and methods are provided for providing fault mitigation in a vehicle system having a high side driver (HSD) and a low side driver (LSD). The system includes a first HSD and multiple first LSDs. The system also includes a selected plurality of first actuators, wherein each actuator is connected to the first HSD and to a corresponding one of the first LSDs to operate in the first mode of operation. The system further includes a second HSD and a plurality of second LSDs. The system also includes a selected plurality of second actuators, wherein each actuator is connected to the second HSD and to a corresponding one of the second LSDs to operate in the second mode of operation. When a failed component sets a fault, the corresponding HSD is switched off and the other HSDs are switched on, enabling the vehicle system to operate in a fault-free operating mode.

Description

technical field [0001] The present invention provides a system and method for providing fault mitigation for electric / hybrid vehicles with high-side and low-side drivers. Background technique [0002] Actuators such as solenoids, pumps, valve assemblies, servo motors, or relays can be used in various vehicle systems such as propulsion systems, exhaust systems, air management systems, or other vehicle systems to operate such as clutches, brakes or valve device. In propulsion systems, solenoids engage or disengage gears or clutches. In emissions systems, solenoids regulate the flow of exhaust gas into the intake manifold. In air management systems, valve assemblies divert airflow and / or vacuum. In the control of such vehicle systems, electrical power may be provided to the actuators through a power module having high and low side drivers. The high- and low-side drivers can be solid-state switches, such as metal-oxide-semiconductor field-effect transistors. Regardless of t...
