Original Abstract Submitted
An automotive vehicle braking system comprising an electronic control unit (ECU) for the vehicle electrically connected to a vehicle controller area network (CAN) bus, an electro-hydraulic power steering (EHPS) system electrically connected to the ECU via the vehicle CAN bus, the EHPS system configured to generate a signal including the state of the EHPS system, an electrically driven power steering pump connected to the EHPS system, and an electronic stability controller configured to receive the signal from the EHPS system, evaluate the signal to determine if the EHPS system is in a fault state, receive supplemental signals, evaluate the supplemental signals for supplemental pressure requests, arbitrate the supplemental pressure requests and the EHPS system fault state to determine a pressure actuation, and in response to the determination of the pressure actuation, control the electrically driven power steering pump to increase hydraulic pressure within the EHPS system.
