Abstract

Described herein are various systems and processes for predictive operating assistance of vehicles. The systems and techniques described herein may be applicable to vehicles such as vehicles operated by a driver, semi-autonomous vehicles, and/or autonomous vehicles. The assistance techniques described herein may be predictive. That is, the techniques allow for the prediction of non-optimal or dangerous operating conditions before the vehicle control is compromised. Accordingly, a warning may be provided and/or operation of the vehicle may be changed based on the predictive assistance determinations. In certain embodiments, the techniques described herein may provide warnings to a driver, may detect faults within the vehicle, may aid in route planning, may detect obstacles proximate to the vehicle, and/or may aid in the operation of the vehicle.

Claims7

Dependent claims

An autonomous vehicle comprising:

a body;
a first wheel assembly, comprising a first wheel and a first tire coupled to the first wheel;
a first electric motor, configured to power the first wheel assembly;
a second wheel assembly, comprising a second wheel and a second tire coupled to the second wheel;
a second electric motor, configured to power the second wheel assembly;
a wheel slip sensor, configured to determine a slip angle of the first tire and provide slip angle data;
and
a controller configured to:
determine, from the slip angle data, a baseline slip angle of the first tire;
determine that the baseline slip angle is greater than a threshold slip angle;
determine, based on the determining that the baseline slip angle is greater than the threshold slip angle, that an alignment of the first wheel assembly is misaligned;
change, based on the determination that the alignment of the first wheel assembly is misaligned, a first power output of the first electric motor relative to a second power output of the second electric motor;
and
output a warning that the alignment of the wheel assembly is misaligned.
