20100235065 | METHOD FOR OPERATING A VEHICLE BRAKE SYSTEM - 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 (μ) 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. | 09-16-2010 |
20100280724 | METHODS AND SYSTEMS FOR CALIBRATING BRAKING SYSTEMS AND CONTROLLING BRAKING IN VEHICLES - A method for controlling braking in a vehicle having a brake pedal includes the steps of obtaining a first measure of braking intent based on movement of the brake pedal, obtaining a second measure of braking intent based on a force applied to the brake pedal, controlling the braking based on the first measure provided that a transition parameter is less than a first predetermined value, controlling the braking based on the second measure provided that the transition parameter is greater than a second predetermined value, and controlling the braking based on the first measure and the second measure provided that the transition parameter is greater than the first predetermined value and less than the second predetermined value. | 11-04-2010 |
20110015845 | METHODS AND SYSTEMS FOR CONTROLLING BRAKING OF A VEHICLE WHEN THE VEHICLE IS STATIONARY - 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. | 01-20-2011 |
20110049974 | METHODS AND SYSTEMS FOR BRAKING DIFFERENT AXLES OF A VEHICLE USING A DECELERATION VALUE - A method for controlling braking of a vehicle having a first axle and a second axle includes the steps of obtaining a deceleration value pertaining to an input from a driver of the vehicle, braking the first axle with a first pressure, braking the second axle with a second pressure that is substantially equal to the first pressure if the deceleration value has not exceeded a predetermined threshold, and braking the second axle with a third pressure that is greater than the first pressure if the deceleration value has exceeded the predetermined threshold. | 03-03-2011 |
20110130935 | METHODS AND SYSTEMS FOR BRAKE PEDAL TUNING AND BRAKING CONTROL IN VEHICLES - 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. | 06-02-2011 |
20120133202 | DYNAMIC REGENERATIVE BRAKING TORQUE CONTROL - Methods, systems, and program products for adjusting regenerative braking torque in a vehicle having wheels and a regenerative braking system providing the regenerative braking torque are provided. A deceleration of the vehicle is determined. A wheel slip of the wheels is determined. The regenerative braking torque is adjusted for the regenerative braking system using the deceleration and the wheel slip. | 05-31-2012 |
20140081545 | METHODS AND SYSTEMS FOR CONTROLLING BRAKING OF A VEHICLE WHEN THE VEHICLE IS STATIONARY - 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. | 03-20-2014 |
20140103722 | ELECTRICAL SYSTEM AND METHOD FOR A HYBRID-ELECTRIC VEHICLE - 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. | 04-17-2014 |
