Abstract
A system and method of maintaining a vehicle on a driver intended path is disclosed. The method includes steps of detecting a failure in a power steering system and controlling a braking system to maintain the motor vehicle approximately on a driver intended path. The driver intended path can be a straight path or a curved path.
Claims20
A method of operating a motor vehicle, comprising the steps of:
- receiving information related to a failure of a power steering system;
- receiving information from a plurality of sensors related to an operating condition of the motor vehicle;
- calculating a driver intended path for the motor vehicle;
- operating an electronic stability control system to maintain the motor vehicle along a corrected path for a predetermined time, wherein the corrected path is substantially closer to the driver intended path than an uncorrected path;
- and
- stopping the operation of the electronic stability control system after the predetermined time has passed.

A method of operating a motor vehicle, comprising the steps of:
- receiving information related to a failure of a power steering system;
- receiving information from a plurality of sensors related to an operating condition of the motor vehicle;
- calculating a driver intended path for the motor vehicle;
- and
- operating an electronic stability control system to maintain the motor vehicle along a corrected path for a predetermined time, wherein the corrected path is substantially closer to the driver intended path than an uncorrected path;
- wherein the step of operating the electronic stability control system includes a step of controlling braking pressure of at least one brake of the motor vehicle.
3 more elements
A system for use in a motor vehicle, comprising:
- a braking system;
- an electronic control unit configured to receive information related to a failure of a power steering system;
- the electronic control unit also configured to receive information from a plurality of sensors related to an operating condition of the motor vehicle and to calculate a driver intended path for the motor vehicle;
- and
- an electronic stability control system that, upon receiving notification that there was a failure of the power steering system:
- receives information related to the driver intended path;
- and
- maintains the motor vehicle along a corrected path for a predetermined time by controlling the braking system, wherein the corrected path is substantially closer to the driver intended path than an uncorrected path.
