  • Manual transmission neutral switch diagnostic and movement prevention method and system
    Patent number: 8386132
    Abstract: A method and system for preventing vehicle movement during start-up arising from a false-neutral indication. Using signals from one or more wheel speed sensors of the vehicle, a vehicle processor determines if the vehicle is moving during start-up, and if so, outputs a termination signal to shut-down the vehicle before any additional movement occurs.
    Type: Grant
    Filed: January 11, 2010
    Date of Patent: February 26, 2013
    Assignee: Chrysler Group LLC
    Inventors: Chad E. Marlett, Adam C. Chiappetta
  • Vehicle descent control
    Patent number: 8121769
    Abstract: Vehicle descent is controlled in at least one implementation by comparing an engine braking torque to a target engine braking torque, and controlling one or more vehicle brakes to maintain the engine braking torque substantially at the target engine braking torque. The target engine braking torque may be varied as a function of one or more factors or conditions, such as accelerator position or brake application pressure.
