A method for controlling brake pressure during a shift of a vehicle out of park may include determining that a first status condition is met when the vehicle is in park with an electric parking brake applied, determining that a second status condition is met when the vehicle is not moving, responsive to detecting a shift of the vehicle out of park when the first and second status conditions are both met, directing a build-up of brake pressure until a brake pressure target is reached, and holding the brake pressure at the brake pressure target until a release condition is met.

Methods for controlling vacuum within a brake booster by modifying powertrain operation include determining an intake manifold vacuum in response to actuation of a brake pedal. Increasing the intake manifold vacuum if the brake booster vacuum is less than a desired brake booster vacuum. In some embodiments, the transmission is downshifted to increase engine speed and intake manifold vacuum.

Systems and methods provide accurate determinations of relevant vehicle mass that can take into account any load being carried and/or towed by a vehicle, such as an electric vehicle or hybrid vehicle. Systems and methods also provide accurate road load measurements that can take into account road gradient(s) and the impact of gravity. Accordingly, the dynamic nature of relevant vehicle mass and road load can be captured. Efforts to optimize operation and/or take preemptive action to provide more efficient performance, enhance the drive experience, etc. can be better achieved through the more accurate determinations of relevant vehicle mass and road load achieved by these systems and methods.

A method of controlling a powertrain of a vehicle includes opening and/or closing one or more of a first switching device, a second switching device, a third switching device, and engaging and/or disengaging at least one of a pair of actuators for a starter mechanism or a motor/generator clutch. Many different control modes are provided for the powertrain by changing the operation of a motor-generator between a motor or a generator, and changing the electrical connections between a first energy storage device, a second energy storage device, an auxiliary electric system, the starter mechanism, and the motor-generator.

A system, apparatus and method for controlling operation of a vehicle. Driver assistance system (DAS) data may be used for controlling one or more function of the vehicle via a driver assistance system. Driver profile data (DPD) is generated and/or received that includes training data from sensor monitoring of a driver's usage characteristics for at least one feature of a vehicle type during a driver-controlled mode of vehicle driving. The DPD is processed with the DAS data to determine if the DPD conform to one or more safety metrics. A driver profile data file may be created by weighing the portions of the DAS data with the DPD that do not conform with the safety metrics. One or more functions on the vehicle may be controlled via the driver profile data file using the driver assistance system during one of a semi-autonomous and fully autonomous mode of operation.

A method for operating a speed control system of a vehicle is provided. The method comprises receiving one or more electrical signals representative of vehicle-related information. The method further comprises determining, based on the signals representative of vehicle-related information, whether one or more predetermined conditions are met. The method still further comprises automatically determining a baseline set-speed for the speed control system when it is determined that at least certain of the one or more predetermined conditions are met. The method yet still further comprises adjusting the baseline set-speed to determine an instantaneous set-speed of the speed control system based on a signal indicative of a desired comfort level. A speed control system comprising an electronic control unit configured to perform the above-described methodology is also provided.

Automatically regulating vehicle longitudinal dynamics in accordance with a preceding vehicle includes determining a first state variable dependent on vehicle acceleration, a second state variable dependent on engine drive torque, a third state variable dependent on the operating state of at least one permanent brake, and information about the preceding vehicle, and adjusting at least one regulating parameter of a regulation function and regulating the longitudinal dynamics depending on the at least one regulating parameter. A first sensor determines the vehicle speed, a second determines the drive torque, a third determines the operating state of the at least one permanent brake, a fourth determines information about the preceding vehicle and an analysis/adjustment/regulating unit analyzes the speed, the drive torque, the operating state of the at least one permanent brake and the information about the preceding vehicle, adjusting the at least one regulating parameter and regulating the vehicle longitudinal dynamics depending on the at least one regulating parameter.

A method of controlling the deceleration of a vehicle to account for an increase in friction in the vehicle brake system as the vehicle decelerates. The method comprises receiving a signal indicative of a value of the speed of the vehicle and a signal indicative of a value of a brake pressure in the vehicle brake system. The method further comprises comparing the vehicle speed value and the brake pressure value to respective thresholds. The method still further comprises increasing the drive torque applied to one or more wheels of the vehicle when the vehicle speed value falls below the threshold to which it was compared and the brake pressure value exceeds the threshold to which it was compared, such that the increased drive torque acts against the braking of the vehicle as the vehicle is decelerated to a stop.

Methods and systems for reducing vehicle and animal collisions. One system includes an electronic processor configured to receive vehicle data. The electronic processor is also configured to determine a collision risk of the vehicle based on the vehicle data, the collision risk representing a probability of a collision between the vehicle and an animal.
