Abstract: A vehicle battery charge management system includes multiple vehicle components each configured to implement a different operational feature of a vehicle, a battery system, and a vehicle control module. The vehicle control module is configured to obtain a state of charge of the battery system, receive a time period specified by user input, the time period indicative of a window of time where the vehicle will be in a parked state, disable at least one of the multiple vehicle components during the time period, and determine an estimated remaining mileage value according to the state of charge of the battery system, a remaining time in the time period, and a predicted energy consumption of each of the multiple vehicle components that are not disabled during the time period, the estimated remaining mileage value indicative of a driving mileage capacity of the vehicle at an expiration of the time period.

Abstract: A method that compensates for fluid pressure variations in a vehicle brake system so that the fluid pressure, brake torque and/or brake force at the wheel more accurately reflects that requested by the driver. In an exemplary embodiment, the method determines the braking intent of the driver, determines a current stage of the braking event (e.g., an apply stage, release stage, etc.), uses the braking event stage and the driver braking intent to select a pressure compensation, and uses the pressure compensation to generate compensated brake command signals for operating the vehicle brake system. This method is well suited for use with brake-by-wire systems, such as an electrohydraulic braking (EHB) system.

Abstract: An electrical system includes a battery for providing electrical power to a starter mechanism and an auxiliary load of a hybrid-electric vehicle. An electric double-layer capacitor (“EDLC”) is electrically connectable to the battery and the auxiliary load. A separation switch is electrically connected between the battery and the EDLC for electrically separating the battery from the EDLC and the auxiliary load. The separation switch is opened in response to the voltage across the battery being less than the voltage across the EDLC.

Abstract: A method for controlling braking of a vehicle includes the steps of calculating a first pressure based on a driver request, and providing pressure that does not exceed a predetermined pressure threshold if the vehicle is stationary and the first pressure is less than the predetermined pressure threshold.

Abstract: A method for calibrating a braking system of a vehicle having a brake pedal includes the steps of measuring, via a sensor, a speed of the vehicle, generating, via a processor, an optimized mapping relating a movement of the brake pedal and a deceleration of the vehicle based at least in part upon the speed of the vehicle, and calibrating, via the processor, a relationship between an engagement of the brake pedal and the deceleration of the vehicle using the optimized mapping.

Abstract: A method that compensates for temperature-related effects in a vehicle brake system. According to one embodiment, the method determines the temperature of a brake pad, calculates a temperature-based modifier, and then uses the temperature-based modifier to adjust one or more brake command signals provided to the vehicle brake system so that they are compensated for temperature-related changes in the coefficient of friction (?) of the brake pad and rotor. The method may be used with brake-by-wire systems such as electrohydraulic braking (EHB) systems and electromechanical braking (EMB) systems.
