Abstract
A method of parking a vehicle includes calibrating a wheel speed count of the vehicle based on a measured length that is external to the vehicle, and parking the vehicle based on the calibrated wheel speed count.
Claims14
A method of parking a vehicle, comprising:
- acquiring a measured length representing a distance travelled by the vehicle;
- in response to an indication that a calibrative disruptive condition, including acceleration or deceleration exceeding a predetermined threshold, occurred while the measured length was acquired, discarding the measured length;
- in response to an absence of the indication, correlating the distance traveled to a vehicle wheel parameter;
- and
- parking the vehicle based on the correlation.
2 more elements
A non-transitory computer-readable medium tangibly embodying computer-executable instructions that, when executed by a processor, cause the processor to
- acquire a measured length representing a distance travelled by a vehicle;
- in response to an indication that a calibrative disruptive condition, including road grade exceeding a predetermined threshold, occurred while the measured length was acquired, discard the measured length;
- in response to an absence of the indication, correlate the distance traveled to a vehicle wheel parameter;
- and
- execute a vehicle parking algorithm based on the correlation.
2 more elements
A vehicle, comprising:
- a controller programmed to
- acquire a measured length representing a distance travelled by the vehicle,
- in response to an indication that a calibrative disruptive condition, including a vehicle skid, occurred while the measured length was acquired, discarding the measured length,
- in response to an absence of the indication, correlating the distance traveled to a vehicle wheel parameter, and
- park the vehicle based on the correlation.
