  • System and method for controlling a brake system in a vehicle
    Patent number: 9981649
    Abstract: A method for controlling a brake system in a vehicle includes providing a first non-friction braking torque for an axle of the vehicle when the vehicle has a first load. A second non-friction braking torque lower than the first non-friction braking torque is provided for the axle when the vehicle has a second load lower than the first load. Non-friction braking at the axle is limited by the first and second non-friction braking torques when the vehicle has the first and second loads, respectively.

  • Steering and braking control system
    Patent number: 9925988
    Abstract: A control system for a vehicle includes a computer. The computer is programmed to command application of one of up to a predetermined steering torque value and up to a predetermined net asymmetric braking force value. Each predetermined force is selected to achieve a predetermined vehicle yaw torque that is at most the lesser of a first maximum yaw torque resulting from actuating a steering system and a second maximum yaw torque resulting from actuating a brake system.

  • Hands-off steering wheel governed by pedestrian detection
    Patent number: 9612596
    Abstract: A vehicle may be steered without a driver's hands being on a vehicle steering control mechanism. A presence of an object within a predetermined distance of the vehicle may be detected using data from at least one object detection sensor that provides data to at least one of a passive safety system, a lane control system, a speed control system, and a brake control system. A steering control mechanism hands-on mode can then be enabled based at least in part on the presence of the object.

  • SYSTEM AND METHOD FOR CONTROLLING A BRAKE SYSTEM IN A VEHICLE
    Publication number: 20130297164
    Abstract: A method for controlling a brake system in a vehicle includes using a first brake pedal map when the vehicle has a first load; the first brake pedal map allows a first predetermined non-friction braking torque to be reached. The method further includes using a second brake pedal map allowing a second predetermined non-friction braking torque, lower than the first predetermined non-friction braking torque, to be reached. The second brake pedal map is used when the vehicle has a second load lower than the first load.
