  • Publication number: 20110303497
    Abstract: Methods and systems for controlling braking in a vehicle are provided, for example in a vehicle in which regenerative braking is provided using a motor capable of providing regenerative braking on one axle or wheel that does not have a friction brake component. If it is determined that the energy storage system of the vehicle cannot accept additional electrical energy created by the regenerative braking, the electrical energy is transferred to another location such as a motor on another axle or wheel, resulting in a propulsion torque on that axle. In order to maintain the total desired braking consistent with the driver command, friction braking is provided on the axle the regenerative braking energy is transferred to using a friction braking component, based in part upon the amount of propulsion torque, when the energy storage system cannot accept additional electrical energy.

  • Publication number: 20100204897
    Abstract: A method of operating a vehicle comprising an adaptive cruise control system and an engine control module is provided. The engine control module is coupled to the adaptive cruise control system. The method comprises issuing a speed reduction signal from the adaptive cruise control system, verifying a speed reduction with a first sensor using the adaptive cruise control system, verifying the speed reduction with a second sensor using the engine control module, thereafter, receiving a resume signal from an operator input device, and executing a speed increase of the vehicle with the engine control module in response to receiving the resume signal with the engine control module.
